Summary of power inspection work

Example of summary of power inspection work

Power inspection work is a major event related to social stability. The following is a summary of power inspection work that I have collected and compiled. Welcome to read.

Summary of Electric Power Inspection Work 1

In 20xx, our team always adhered to the policy of "safety first, prevention first, comprehensive management" and thoroughly implemented the "Emergency Response and Investigation of Electric Power Safety Accidents" "Regulations on Handling" and implemented the spirit of the State Grid Corporation's "Emergency Notice on Earnestly Doing Current Safety Production Work". Compared with last year, great progress has been made in the prevention and control of external damage and anti-violation work. The safety work in 20xx is now The summary is as follows:

Anti-violation work:

In 20xx, the team *** self-examined 16 violations, including 13 general behavior violations; 3 general management violations; and 0 general device violations. times, 8 violations were investigated and dealt with in the workshop, including 5 violations for general behavior, 3 violations for general management, and 0 violations for general equipment, and no violations of a serious or above nature occurred.

Prevention and control of external force damage:

In the prevention and control of external force damage in 20xx, we persisted in dealing with the government and relevant departments, and combined with the mass line protectors to timely grasp the on-site conditions of hidden danger points caused by external force, Arrange personnel to be on-site for important external force damage. In the case of external damage caused by external forces during the construction of public rental housing in the university town of the 500kV Banchen Line and the construction of the 500kV Hongban Line high-speed railway, the line inspection team increased manpower and material resources and arranged personnel to be on duty 24 hours a day during the construction period. During the monthly inspections The number of special inspections was increased, and team leaders and workshop leaders actively negotiated with the local government, effectively curbing the expansion of hidden dangers.

Safety education and training:

Four important safety education trainings were conducted *** this year. Other trainings were carried out in combination with technical training. The training items are 1. Work ticket management regulations, fill in Regulations; 2. Training on heatstroke prevention and cooling, snake and insect prevention knowledge; 3. Learning of emergency plans for preventing wildfires, icing, thunderstorms, and typhoons; 4. First aid training for electric shock. During the training process, everyone brainstormed and proposed their own good ways to learn safety knowledge and various emergency plans.

Safety Day activities are carried out:

This year, we carefully completed the study of monthly documents and accident cases, videotaped and recorded safety meetings throughout the year, and retained them according to the company's prescribed time. Repeatedly study and understand the spirit of important issued documents such as the "Regulations on Emergency Response, Investigation and Handling of Electric Power Safety Accidents" (State Council Order No. 599); "Emergency Notice on Earnestly Doing Current Safety Production Work". At each safety learning meeting, each team member expressed his opinions based on his understanding of the safety documents, the spirit of the accident cases and the focus of his own inspection work.

The overall idea of ????safety work in 20xx:

Strengthen the examination study of safety knowledge, improve the safety awareness of team members through safety study meetings; carry out anti-violation work as scheduled, and eliminate serious and above violations occurrence; strengthen the prevention and control of external damage to ensure safe and economical operation of the line.

The actual progress of safety work in 20xx:

At the safety meeting, individual team members did not have a clear understanding of safety learning and made hasty speeches. There were certain deficiencies in the quality of the video recordings of the safety meeting. , there is a certain deviation between the meeting time and the company's requirements; anti-violation investigation and punishment are limited to the collection of team information and violations discovered by leaders on-site special inspections; safety training focuses on the study of relevant materials, and less actual safety precautions are learned; external forces Individual points of damage are still under construction, and important mass line protectors are not in place.

Reflection on the development of safety work in 20xx:

Due to work tasks, safety learning meetings are only held at the end or beginning of each month, and the time is relatively hasty, thus making safety learning The quality is not very good; safety education and training are mostly conducted indoors, there are no special training locations outdoors, and the operating lines are live, so training is generally not conducted on them; external sabotage is not strong enough when negotiating with the government, and the government ignores us. ; Individual employees habitually commit some violations at work.

Overall measures for the safety work in 20xx:

The safety work in 20xx achieved good results but also exposed many problems. In the "reflection after action" of the safety work in 20xx On this basis, the safety work in 20xx cannot fall behind. In order to ensure the smooth progress of safety work throughout the year 20xx, the preliminary rectification measures and plans are as follows:

1. The safety learning meeting is "strictly organized", that is, Make sure that the time for each safety study is not very different from the company's regulations, and that personal speeches are actually recorded without adding unnecessary rhetoric. Points management will be carried out for team members who speak in safety learning. Those who fail to speak many times will be included in the violation assessment. Safety officers should collect more relevant safety information before learning, and are not limited to issuing safety learning materials every month.

2. Collect vehicle inspection photos on a regular basis every month to ensure the safety of each vehicle trip, and conduct planned safety learning for drivers in the group.

3. Pay attention to the key points in anti-violation work, and exclude fabricating violations in order to realize the number of violations investigated. Dozens of typical serious violations and particularly serious violations of the company must be strengthened in the group's violation analysis meeting. , in the violation analysis meeting, the violator should give a more detailed explanation of his or her violation process and the violator's thoughts at the time, and how the violator should prevent similar violations in the future. The violation analysis meeting can be conducted in conjunction with the safety study meeting.

4. External damage must be dealt with "for people and things". Prevent and control external damage in strict accordance with the company's hidden danger investigation and management work manual. Failure to conscientiously do a good job in the prevention and control of external damage in the responsible section will affect line safety. will be assessed as appropriate.

5. Safety education and training are conducted once a month. Technical lectures and practical safety protection training should be carried out intermittently. Due to the special work, 4 outdoor trainings and 8 indoor trainings are carried out throughout the year. Special training Study according to the regulations during the month.

Under the good safety prospects of the company, I will deeply remember that "safety is the foundation of an enterprise's survival, development, and image." Always remember the important position of safety in the enterprise, work hard to do the job of the safety officer, and work hard to ensure safety every day in 20xx. Summary of power inspection work 2

1. Basic situation

(1) Overhead transmission line professional work organization structure and main personnel status

As of December 18, 20xx, there were ***26 Nanchong central line professionals, including the deputy director in charge of the central line 1, 1 line operation and maintenance technical supervisor, and 24 line operation and maintenance personnel. The center currently has two professional teams, Line Operation Inspection Class 1 and Line Operation Inspection Class 2, with 5 people capable of tower climbing and maintenance operations and 6 new personnel.

(2) Basic situation of the lines under its jurisdiction

At present, the center has 10 lines under its jurisdiction, with a total length of 539.983 kilometers and 1,144 poles and towers. The line corridor passes through Gaoping District, Shunqing District, Jialing District, and Xichong County in Nanchong City; Qu County and Da County in Dazhou City; Guang'an District and Yuechi County in Guang'an City. Among them, four lines, 500kV Nantan Line 1 and 2, and 500kV Nanhuang Line 1 and 2, are assets of Huazhong Network Company and are currently maintained by Sichuan Provincial Company.

(3) Basic situation of newly put into operation

None

2. Main work situation of operation management

(1) Line professional The main situation of management work

In 20xx, the center focused on and consolidated basic management work, and successively introduced or improved the Nanchong Center's "Inspection Management Measures (Trial)", "Special Inspection Implementation Rules (Trial)", "Defect Management System (Trial)", "Mass Line Protection Implementation Rules (Trial)", "Line Operation Inspection Team Construction Standards (Trial)" and other rules and regulations promote the improvement of management level by grasping the grassroots, grasping the basics and grasping basic skills.

The center analyzes and summarizes the line work every month and quarter, holds a solid line operation analysis meeting, sorts out the line work situation of the previous month, analyzes the nature of line defects, implements the defect handling methods and responsible persons, and arranges the next In addition, the center strictly implements pre- and post-shift maintenance meetings, and conducts careful analysis and summary after each power outage maintenance, laying a solid foundation for the safe and smooth completion of 10 line maintenance throughout the year.

(2) Line operation and maintenance

(1) Periodic inspection work

First, adhere to periodic standardized inspection work. During the inspection, it is required to inspect the equipment itself, ancillary facilities and the external environment. Inspections must be carried out in strict accordance with the inspection contents and items in the "Line Standardization Inspection Card", and the problems discovered shall be classified and recorded according to the standards.

The second is to adhere to the inspection responsibility system, and implement fixed routes, fixed posts, and fixed personnel for line inspections. Each line has clear personnel for regular inspections, and the inspection effectiveness rate is linked to economic benefits. If the line inspections are not in place, Strict performance penalties will be imposed accordingly. At the same time, line exchange inspections were carried out at the end of the year, and people and lines were changed, which effectively made up for the shortcomings of long-term line setting and personnel inspections.

The third is to adhere to the combination of inspections and rectification of deficiencies, and give full play to the advantages of integrated transportation and inspection. For defects that do not require power outage, the inspection personnel are arranged to handle them together during the periodic inspection, which not only saves operation and maintenance costs, but also improves the efficiency of line defect elimination.

The fourth is to strengthen the quality of periodic inspections, perform hierarchical supervision and inspection work by squad leaders, dedicated directors, and directors in charge, strictly implement the inspection and assessment system, and use digital photography, GPS data positioning collection and other means to strengthen operations during inspections. manage.

(2) Special inspection work

Special line inspection work is carried out in a targeted manner based on seasonal characteristics. During peak summer and winter peak periods, special inspections were carried out on the 500kV Guanghuang First and Second Lines of the power plant’s transmission lines, and the 500kV Huangwan First and Second Lines of the Sichuan-Chongqing section lines. Infrared temperature measurement and other technical means were widely used in special inspections, focusing on observing the heating conditions of main stress-bearing components; actual measurements of important crossings, clearance distances of structures, ground distances, and wind deflection distances were carried out; emphasis was placed on the discovery of external hazards, and timely Hidden dangers such as external construction were dealt with.

Based on the special work of the line, special inspections were carried out. During the flood control period, a special inspection team was arranged to conduct special inspections of the important crossings of the central line, the river crossing tower base, and the Lamen Tower; in order to prevent the line threats caused by geological disasters, a special geological disaster cleanup project was carried out on the lines within the line's jurisdiction. Inspected and subdivided geological disaster sections such as cliffs, cliffs, dangerous rocks, passes, river valleys, paddy fields, and mining areas, and further improved the central geological disaster section ledger; in order to prevent the possible impact of freezing rain and snow, A special anti-icing inspection was organized on the designed ice areas and high-altitude towers of the 500kV Huangda Line and 500kV Bada Line. In order to ensure the quality of maintenance and strict closed-loop management of defects, the center combines diagnostic inspections before maintenance with inspection work. Before the power outage maintenance work, a diagnostic inspection of the line was carefully organized to fully understand, control and judge the line operating conditions and hidden dangers and defects, which effectively ensured the implementation of the maintenance work.

The center is responsible for insisting on participating in line inspections at least once a month, conducting thorough inspections and spot checks on periodic line inspections, and organizing diagnostic inspections before large-scale maintenance, so as to gain an in-depth understanding of the operating status and performance of each line. The work status of the inspection personnel can be better guided by the actual line inspection work from point to area. The leaders of the center conduct inspections and inspections from time to time, inspect the effectiveness and quality of inspections, and provide guiding opinions on line inspections.

　(3) Channel management work

This year, the center vigorously carried out line channel renovation work, combined with the company's special channel renovation work, eliminated all serious and critical defects in the channel, and carried out inspections on the trees and bamboos in the line channel. More than 5,300 branches were cut and pruned, effectively preventing accidents such as line grounding and wire burn due to discharge from super-high trees in the channel.

(4) Protection of electric power facilities

The center always regards the protection of electric facilities as one of the basic tasks of the central line management and pays close attention to it, and strengthens the technical support of electric power facilities. intensity of protection. Combining technical defense, civil defense, and physical defense according to local conditions, establish a long-term mechanism for the protection of power facilities, and create a good environment for the safe operation of the power grid. First, in response to behaviors endangering power lines, the center has issued written "Notifications of Potential Safety Hazards" and "Notices of Rectification" to relevant responsible units and responsible persons many times, and has also issued notifications to the "Three Electricity Offices", the Economic Bureau, and the Work Safety Supervision Bureau. The bureau and other government functional departments issued safety hazard letters and actively sought government support and intervention, effectively preventing and stopping many cases of building houses in line protection areas, especially the construction of large pig farms in the 57#-58# section of the 500kV Nantan Second Line. and other events. The second is to strengthen communication with local governments by convening symposiums on the protection of electric power facilities, and establish a "three-level network" mechanism of the center, the government, and the masses to effectively combat crimes against electric facilities and prevent units or individuals from violating regulations in line protection areas. Actions such as building buildings have important meanings. Third, in conjunction with the Safety Production Month activities, the center further increased the publicity of power facility protection, produced various promotional materials, and went deep into towns and villages to carry out power facility protection publicity, achieving good results and greater influence.

(5) Mass line protection work

The center steadily promotes and improves the mass line protection system, and always adheres to the concept of "mass line protection is a necessary supplement to line operation and maintenance", relying on Instead of relying on the power of mass line protectors, we can stimulate the work enthusiasm of mass line protectors through reasonable compensation for lost work and appropriate rewards. Give full play to geographical advantages, mobilize and use the power of the people to publicize and protect power facilities along the lines and within the wider scope of influence, and promptly grasp on-site direct and intuitive first-hand information on abnormal conditions of the lines to make up for the periodicity During the time gap between inspections and special inspections; relevant training work has been carried out to further give full play to the role of on-site supervisors, intelligence officers, maintainers, propagandists, coordinators, and investigators for mass line protection, and improve the efficiency and effectiveness of line operations. At the same time, a series of assessment systems such as the "Mass Line Protection Management System" and "Transmission Line Inspection Assessment Methods" were formulated to standardize line protection work and ensure the stability of the line protection team and the steady improvement of line protection quality. This year, the mass line protection work of Nanchong Center has been praised by superiors many times. The effect of mass line protection has been fully demonstrated especially in the "7.18" flood and the fault finding of the 500kV Nantan Second Line due to wildfire tripping.

(3) Line overhaul and technical transformation work

In 20xx, the Nanchong Central Line Professional Commission issued 8 overhaul plans, including the overhaul of the 500kV Banan Line and the 500kV Nantan Line. Comprehensive lightning protection system installation, 500kV Nantan Second Line overhaul, 500kV Huangda Line overhaul, 500kV Bada Line overhaul, 500kV Bada Line standard project overhaul, 500kV Banan Line standard project overhaul and 500kV line intelligent bird repellent device installation. According to the actual situation of the project, the method of outsourcing operations and central personnel participating in full quality supervision was adopted to ensure the progress and quality of the overhaul work. As of December 20, the center has completed final accounts for all major repair projects this year.

(4) Line status maintenance work

1. As of the end of 20xx, Nanchong Center had carried out a total of 10 rounds of transmission line status maintenance, with a total length of 539.983km. Among them, there were 2 times in the normal state, 6.523km, accounting for 1.2; 5 times in the attention state, 328.326km, accounting for 60.8; 2 times in the abnormal state, 164.469km, accounting for 30.5; 1 time in the severe state, 40.2km, accounting for 7.5.

2. The central line major conducted a preliminary status inspection of the 10 lines under its jurisdiction in accordance with the arrangements of the ultra-high voltage company. During the entire process, the five major systems of condition maintenance were strictly implemented, relevant information and documents were collected and sorted one by one, basic condition maintenance data such as line operation, maintenance and testing were established, and the lines were scored according to the "Implementation Rules for Condition Maintenance of Overhead Transmission Lines", and the results were obtained Received preliminary evaluation reports and maintenance suggestions for teams and centers. In this regard, the provincial company's condition maintenance acceptance team fully affirmed, especially the basic data management of the line and the layout of the tool room. However, during the process of condition maintenance, we also discovered some serious problems, such as the unreasonable evaluation scores of some units, and the overall evaluation of the line is often judged to be in a caution or abnormal state due to individual general defects.

(5) Special technical work

1. Lightning protection work

Nanchong Center always insists on taking lightning protection work on transmission lines as a way to reduce line tripping rates and improve line Reliability is one of the core professional tasks to ensure the safety and stability of the 500kV power grid. Pay attention to the comprehensive implementation of line comprehensive lightning protection at the levels of operation, maintenance, management methods, and technical application. The main manifestations are:

(1) During the daily inspection of lines, strengthen inspections and inspections of lightning protection equipment and grounding devices, promptly deal with and eliminate defects found, and ensure that lightning protection facilities are intact. The center has promptly eliminated defects in 12 grounding wires that were damaged by external forces and exposed.

(2) During power outage maintenance work, ensuring the insulation level outside the line will be one of the key tasks. In 20xx, 167 pieces of self-exploding insulators were replaced by power outage maintenance opportunities to fully ensure that the external insulation of the lines was good.

(3) This year, the center completed the general survey of the grounding network of the lines under its jurisdiction. Based on the shaking survey, it has successively carried out the 54-base grounding network rectification work of the 500kV Nantan Second Line and the 60-base grounding network of the Banan Line. According to the form of the grounding body of the tower, and with full consideration of the inductance effect of the impulse current on the extended grounding body, Φ12 hot-dip galvanized round steel is used to increase the grounding body, the laying position of the grounding body is reasonably selected, and the welding process and burial depth of the grounding body are strictly controlled. , ensuring that the grounding network renovation work is effectively carried out, and has a good effect on reducing the line grounding resistance.

(4) Through statistics on lightning towers along slopes, mountain tops, across ditches (rivers), etc. that are vulnerable to shielding, and combined with data from the lightning positioning system, the center has successively carried out statistics on the 500kV Nantan Line 1 and 2, Bada Line Lines, Huang Wanyi, Second Line, Banan Line, etc. are equipped with 940 lightning protection rods and 80 tower lateral protection pins. In July 20xx, during the handover of the Huangwan Line, the circuit breaker tripped twice during thunderstorms. The substation fault recording and ranging and fault tower inspection results showed that the fault points were all in the Chongqing section where anti-blade lightning rods were not installed. , it can be seen that the installation of anti-blitz and lightning protection devices has obvious lightning protection effect on 500kV lines.

Next year, the center will continue to transform the grounding grid of some lines and install lightning rods, and adopt comprehensive lightning protection measures to further improve the lightning protection capabilities of the lines.

2. Prevention of external sabotage

The center has taken the following measures in response to external sabotage incidents: First, increase publicity and establish a mass joint prevention mechanism. In areas prone to external damage such as areas prone to theft, rock blasting areas, and soil borrowing areas, fixed-point publicity and mass line protection will be adopted to ensure power supply. The second is to strengthen the investigation of hidden dangers before the flood season, increase the intensity and frequency of patrols during special periods, understand the geological hazards of the lines under its jurisdiction, and carry out the overhaul of slope protection and sill protection facilities.

The third is to strengthen close contact with governments and public security agencies along the line to avoid damage to engineering operations, eliminate operational hazards such as illegal tree planting and building construction in the line protection zone, and cooperate with the public security agencies to severely crack down on theft and vandalism. Fourth, safety notification and coordination of construction operations along the lines have been done in advance. Facing the construction of Nandaliang Expressway and Lanzhou-Chongqing Railway crossing lines, the center actively contacted the public (rail) road construction and management units and communicated and negotiated with their responsible persons many times. Verify the impact of engineering design and construction on lines, and urge construction units to take effective safety measures to ensure the safety of construction operations.

3. Anti-pollution flashover work

First, the pollution sources, pollution area distribution, and external insulation configuration of the 1144-base towers of 10 lines were improved.

The second is to use the opportunity of power outage maintenance to conduct salt density sampling of 81 insulators of 27 bases, and conduct salt density sampling on the 500kV Banan Line, Guanghuang Line 1 and 2, Nanhuang Line 1 and 2, and Huangwan Line 1 and 2. Insulator anti-fouling cleaning was carried out on the entire line and some sections of the 500kV Bada Line and Nantan Line 1 and Line 2.

Third, in accordance with the requirements of the State Grid Corporation of China, a total of four strings of composite insulators on the 500kV Banan Line were replaced and inspected.

4. Anti-icing, dancing and other work

In order to prevent possible disasters caused by low-temperature rain, snow and freezing weather, and improve the ability of lines to resist severe natural disasters in micro-meteorological areas, we must do Take good emergency precautions, fully ensure the safety of the power grid and equipment during the peak winter period, improve the timeliness and effectiveness of emergency response and emergency handling, and ensure that emergency response is timely, effective, complete, safe and efficient, and Nanchong Center will do a good job Ten measures to prevent icing and dancing. First, before the arrival of ice and snow weather, special anti-icing inspections and diagnostic inspections of 500kV lines within the area under the jurisdiction of the center are carried out to promptly discover and investigate hidden defects and hazards, and deal with defects in accordance with the principles of light, heavy, slow and urgent. Complete closed-loop defect management to fully ensure the health of transmission lines. The second is to deepen the investigation of hidden dangers on the lines, carry out "look back" work on channel improvements, and improve tree and bamboo felling standards for sections that may be covered with ice. The third is to further sort out and identify the special sections and key towers of the line, focusing on understanding the operating conditions of poles and towers in geological disaster areas, areas damaged by external forces, areas prone to theft, heavily polluted areas, and ice-covered areas, and for important crossing towers and river crossings. Key inspections and inspections will be conducted on towers, sliding door towers, large span towers, and double-circuit towers. The fourth is to carry out key inspections and extended inspections on the 500kV Huangda Line 118#-154# in the high-altitude section and the tower section on the river island of the 500kV Bada Line. Fifth, make full use of the opportunity for line power outage maintenance and carry out electrical defect elimination work. Sixth, carry out infrared temperature measurement of heavy-duty and heavy-load lines, strengthen infrared temperature measurement of wire connection fittings and tension-resistant fittings, and arrange follow-up inspection or maintenance work based on temperature measurement conditions. The seventh is to closely track weather changes, sign meteorological service agreements with local meteorological departments, make full use of information means such as China Weather Online, grasp weather changes in advance, and do a good job in temperature prediction. Eighth, ensure special inspections under severe weather conditions. The ninth is to train line protectors on ice covering knowledge to improve the timeliness of information feedback under severe weather conditions. Ten is to make preparations for emergency rescue equipment and materials. Before the arrival of low temperature weather, preparations for anti-icing protective equipment, snow removal tools, maintenance tools, spare parts and lighting equipment were completed.

5. Wind deflection prevention work

In conjunction with special channel renovation activities, the center carried out intensive felling of super-high and windward bamboo trees in the line protection zone. At the same time, the center organized wind deflection measures on the line. The knowledge training lectures enabled the inspectors to deepen their understanding of wind deflection, avoid misunderstandings about wind deflection by individual personnel, and laid the foundation for correctly judging the hidden dangers of trees and bamboos in the process of channel improvement.

6. Bird prevention work

According to the characteristics of the geographical distribution of the line, focus on collecting the range and areas of bird activity along the line, observing their activity patterns, and establishing recorded observations. Sections with intensive bird activity were recorded.

During the inspection and maintenance process, emphasis was placed on the removal of bird nests along the lines, especially the bird nests above the tower insulators, which were promptly removed to prevent insulator flashover caused by bird droppings. At the same time, overhaul funds were used to carry out bird damage prevention work. Intelligent bird repelling devices have been installed on the 500kV Huangda Line, Hongnan Line and Bada Line.

7. Preventing wildfires

This year, a line tripping incident caused by a wildfire occurred in the center, which caused the company and the center to attach great importance to the prevention of wildfires. The center gives full play to the role of mass line protectors on transmission lines by grasping the situation of mountain fire burning and fire use by governments and farmers along the transmission lines, as well as statistics on mountain fire-prone areas along the lines, and establishes a local network with line protectors as the mainstay and the general public as active members. Participate in the early warning mechanism to prevent wildfires. Establish a wildfire linkage mechanism with local governments, firefighting, etc. Strengthen communication with governments along the line, distribute power facility protection books and print almanacs, strengthen publicity to farmers along the line, and prevent illegal mountain burning and use of fire that may cause harm to the line. ;
