Summary of lightning protection work

Summary of lightning protection work (select 6 articles)

Time flies and hard work has come to an end. During this time, I believe that everyone is facing many challenges and has gained a lot of growth. Let's sum up our past achievements into a work summary. So how is the general work summary written? The following is my summary of lightning protection work (selected 6 articles), welcome to share.

Summary of lightning protection work 1 I. Analysis of basic situation of the line

By the end of 20xx65438+February, there were 7 500kV transmission lines in operation and maintenance in northeast Chongqing, with a total length of 728. 1km and Taki 1543.

The 500 kV line under the jurisdiction of northeast Chongqing has complex terrain and frequent lightning strikes in mountainous areas, which has brought adverse effects on the safe operation of the line: hilly terrain lines account for 4 1.2% of the total length, mountainous areas account for 3 1.5% and mountainous areas account for 27.3%; Topographically, the terrain conditions of the lines under the jurisdiction of northeast Chongqing are relatively bad, and the terrain above the mountainous area accounts for more than half of the total length, and the mountainous area is a lightning-prone area; Therefore, due to the limitation of terrain conditions, the situation of lightning damage in northeast Chongqing is grim and the task of lightning protection is extremely arduous.

The lightning protection design margin of 500kV transmission line in northeast Chongqing is low, which leads to poor lightning protection ability after the line is put into operation: the average weight of the whole tower is 16.6 t, the average call height is 34. 1m, and the overall height is 43.4m m. Because the tower is high, it is easy to cause lightning strikes in mountainous terrain; The average protection angle of the vertical tower is 1 1.4, and the average design value of grounding resistance is 15ω. Because the lightning protection level considered in the original design is already very low, the lightning protection ability of 500kV line itself is very low.

Second, the lightning loss statistics

In 20XX, the lines under the jurisdiction of Northeast Chongqing were struck by lightning twice, and the lightning trip rate was 0.27 times100 km/year, which was lower than the target value of 0. 14 times100 km/year of State Grid Corporation. Lightning strikes on the line are as follows:

(1) On April 9,1:49,500 500kV Bandung Line B tripped and reclosed successfully. The inspectors found that there were obvious discharge marks on the surface of B-phase porcelain insulators of #92 tower 1, 3, 5 and 8 pieces of 500kV Bandung First Line, and there were also discharge marks on the equalizing ring, but there were no discharge marks on the grounding connection point. It is confirmed that this is the B-phase fault point of Bandung first line. From the analysis of fault trip location, combined with traveling wave location, fault recording and lightning location system data, the continuous thunderstorm weather in the area involved conforms to the characteristics of lightning strike fault.

(2) At 7: 40 on September 7th 17, phase C of 500kV Huangwan Second Line tripped and reclosed successfully. During the inspection, it was found that the C-phase composite insulator string of #320 tower of 500 kV Huangwan Second Line had obvious typical lightning arc burn marks, and the equalizing ring had a melting point with a diameter of 0.5CM, and there were many arc burn marks. According to the field measurement, the grounding resistances of the feet A, B, C and D of the tower are 1.4, 1.5 and 65438 respectively. When the line trips, it is thunderstorm weather. Combined with the inspection of the faulty tower, the results of lightning information inquiry and the situation reflected by residents along the line, it is very likely that the trip of the line is a lightning trip. On-site inspection shows that there are no abnormal conditions such as crossing, tree barrier and strong wind, and the insulator surface is very clean, which can eliminate other types of faults except lightning strike.

Three. Lightning Protection Analysis of Northeast Chongqing University

1) The 500kV overhead transmission line in northeast Chongqing has achieved remarkable results by detecting and rectifying the grounding device.

The average design grounding resistance of lightning strike towers in northeast Chongqing is15Ω, which can only meet the requirements of general lightning withstand level (125ka ~ 175ka). Preventing lightning strike back can be achieved by reducing grounding resistance and improving lightning withstand level of lines. Through the grounding resistance test every year before the peak summer in Tohokuin, Chongqing, the towers with unqualified grounding resistance are treated, which better controls the lightning withstand level of 500kV transmission lines and effectively prevents lightning strikes on the lines.

2) The high lightning trip rate is related to the height of the tower, the number of protection angles and the topographic factors of the tower. Due to design reasons and topographic factors, the tower of 500kV line in northeast Chongqing lacks effective lightning protection measures;

There are two ways to reduce shielding failure trip, one is to improve the lightning withstand level by 50%, and the other is to reduce shielding failure probability by changing the number of protection angles. Once the line is completed, there are basically two measures to improve the lightning withstand level. One is to reduce the impulse grounding resistance of tower grounding body, and the other is to appropriately increase the number of insulators to increase the U50% discharge voltage. The maximum shielding failure current of a typical 500kV tower is 50kA. Increasing the 50% discharge voltage of 10% insulator string can reduce the lightning flashover times of this part by about 13.2%. Reducing the number of line protection angles has the most obvious effect on reducing the shielding failure trip rate: from the statistical data, the average protection angle of the straight tower at the lightning strike point of the line is 10.5, and the average designed climbing distance is 2.56 cm/kV, which cannot meet the requirements of the lightning strike trip rate of the line; It can be seen from the calculation that the protection angle of 500kV line starts from 10.5, and the calculated lightning trip rate will be doubled for every 5 steps.

Before the peak summer every year, the planned grounding resistance test rate of 500kV lines completed by Chongqing Northeast Institute is 100%, and the unqualified rate of grounding resistance is rectified 100%. The rectification of grounding grid has been carried out smoothly, and some achievements have been made in reducing impulse grounding resistance. By installing controllable lightning rod and shielding lightning rod, some achievements have been made in line lightning protection and shielding failure.

Chongqing Tohokuin is mainly responsible for the operation and maintenance of 500 kV lines that have been put into operation in Chongqing. After the line is put into operation, it is difficult to improve the lightning withstand level of the line or reduce the protection angle of the line by increasing the number of insulators and changing the layout position of the tower head ground wire, thus reducing the lightning shielding trip rate of 500kV lines. Therefore, the lightning protection work of 500kV lines should be fully considered and demonstrated at the beginning of design, so as to avoid all kinds of passivity of line lightning protection in the process of operation and maintenance in northeast Chongqing.

Summary of lightning protection work 3 Under the correct leadership of the superior competent department, we will conscientiously implement the spirit of instructions on lightning protection and electricity prevention work, constantly improve and perfect working methods, improve safety prevention ability, reduce hidden dangers of accidents to the lowest index, and provide safety guarantee as much as possible to ensure that the development of the school will not be affected.

First, attach great importance to and actively do a good job in lightning protection safety publicity.

We mainly implement this work from the following aspects.

1, set up a lightning protection and safety leading group to lead, coordinate and organize schools to carry out lightning protection and safety education. Conduct lightning protection safety publicity through meetings. The school insists on holding a regular meeting on lightning protection safety, analyzing problems and discussing measures and arrangements. In this paper, the safety problems including lightning protection in schools are analyzed in detail, and many problems that need attention are put forward.

2, organize lightning protection and electricity safety knowledge education activities. The school organizes special lectures and columns on lightning protection knowledge to deepen students' impression. Students have mastered the basic knowledge of lightning protection safety and enhanced their awareness of lightning protection safety. The school also conducted lightning protection training for all staff and students, and conducted actual combat drills, which enabled all staff to master the correct methods and skills of lightning protection and self-rescue, comprehensively improved the awareness of lightning protection safety and the practical ability of preventing drowning and lightning rain, and further promoted the lightning protection education in the school.

3. A systematic and comprehensive lightning protection safety inspection was conducted for the teachers, students and employees of the whole school. A comprehensive inspection was made of the facilities in all important parts of the school.

4. Teachers insist on publicizing lightning protection knowledge and strengthening students' safety education.

Two, promote the lightning protection safety responsibility system, fully implement the management responsibility and specific measures.

1, determine the key parts, define the key parts and the person in charge.

2. Strengthen inspection.

Swimming must be accompanied by parents.

4. Students stay away from deep water sources such as ditches and lakes during holidays.

Third, formulate emergency plans for lightning protection safety

Safety responsibility is more important than Mount Tai, and fire prevention and lightning protection are no small matter. In order to enable students to effectively prevent lightning and floods, lightning protection and self-help drills were held. In order to effectively control students' hidden dangers in the first time, ensure students to avoid risks scientifically, and reduce the accidents of blindness, panic, mutual injury and self-injury, the school organized lightning protection and drowning prevention safety drills.

Fourth, the alarm bell is ringing and the work is done seriously.

In order to avoid all kinds of unsafe factors, teachers must give a safety education one minute before school every day, stipulating that students are not allowed to bathe in the water and play in ditches and lakes. The teachers on duty in the school patrol the campus every day to see if there are any potential safety hazards and eliminate all unsafe factors in the bud.

Due to clear understanding and proper measures, there has never been a drowning accident in our school in the past year. Safety is above all else, and lightning protection and electricity prevention work has a long way to go, not once and for all. While strengthening the daily work management and summarizing the situation at the stage, we have established a safety awareness of nip in the bud. Every teacher can care about lightning protection and safety. With the joint efforts of all teachers, students and staff, the lightning protection safety of the central primary school will be better.

Summary of Lightning Protection Work 4 In order to conscientiously implement the spirit of the Notice of the Municipal Education Bureau on Doing a Good Job in Lightning Protection for Primary and Secondary Schools in the City, avoid or reduce the loss of school property caused by lightning strikes, and ensure the safety of teachers and students, our park has carried out a major inspection on lightning disaster safety prevention throughout the school since September 12. Inspection, education and self-examination are summarized as follows:

First, attach great importance to and raise awareness of the importance of doing a good job in lightning protection.

In recent years, lightning has been increasing in our city, and injury accidents will happen at any time. In addition, with the increasing number of electronic facilities in our park in recent years, the task of lightning protection is even more arduous. At present, staff and students' awareness of lightning protection and lightning protection facilities are relatively weak, and there are great security risks. In this regard, our park attaches great importance to this work, firmly establishes the consciousness of "cherishing life and putting safety first", adheres to the people-oriented attitude and is highly responsible for the safety work of our park, puts safety education on the agenda, carefully organizes and arranges, and strives to achieve tangible results in lightning protection safety. And set up a lightning protection safety working group, with the director as the leader and the deputy director as the deputy leader, to carry out the work according to the lightning protection requirements, and the members of the organization are responsible for organizing the lightning protection safety work within their respective scope. After receiving the documents issued by the superior, immediately organize the whole school staff to study hard, fully understand the importance and urgency of doing a good job in lightning protection and disaster reduction, actively study preventive measures according to the actual situation and seasonal characteristics of the school, and conscientiously implement lightning protection work.

Two, a clear responsibility for lightning protection, and earnestly implement the lightning protection safety work.

Our school is equipped with more than 20 desktop computers for teaching and office, a multimedia classroom, a campus broadcast system and an in-school monitoring system. The application of these advanced electronic information equipment has a positive effect in daily work, but at the same time, the lightning protection work of these electronic information equipment has also become the top priority of lightning protection work. In view of this situation, our park puts the responsibility of these devices on people, and requires the responsible teachers to unplug all devices after work and in thunderstorm weather to minimize and prevent the devices from being damaged by lightning. At the same time, the wires and telephone lines were overhauled to ensure the implementation of lightning protection.

Third, strengthen safety education and raise awareness of lightning protection.

During the inspection, our park widely publicized lightning protection laws and regulations and lightning disaster prevention knowledge to improve the awareness of lightning protection and disaster reduction of all teachers and students. Especially in view of the high degree of lightning disaster and great social impact, combined with the actual situation of the school, through campus radio, meetings and other ways, we vigorously promoted the common sense of lightning protection emergency avoidance, so that all teachers and students know the propaganda of lightning protection and disaster reduction, effectively reducing the impact of lightning disaster and prompting teachers and students to actively participate in lightning protection work.

Fourth, carry out lightning protection inspection to ensure that lightning protection work is in place safely.

Our park has also seriously carried out a safety inspection of lightning protection work. Check the key areas of power distribution introduction places such as teaching buildings, special equipment lines and distribution boxes. The teaching room in our park is equipped with a voltage regulator, and many offices with computers are equipped with UPS power supply. The power inlet line adopts power protector, which has a certain effect on lightning protection. While carrying out major inspections, our park actively carried out lightning protection safety inspections, gradually improved various lightning protection measures, and avoided all kinds of lightning strikes.

Problems with verbs (abbreviation of verb)

Although our park has carried out various lightning protection and safety work in depth and solidly, there are still some problems in the work.

1. Lightning protection facilities are not in place. Due to the lack of funds on the one hand and professional technical guidance on the other, for example, the lightning rod installed on the roof was installed by the original builder when building a teaching building, and the lightning protection coefficient is limited, so it is necessary to reinstall more advanced or effective lightning protection devices.

2. The lightning protection work lacks professional technical guidance. Lightning protection requires high technical level. With the continuous development of modern electronic technology, a large number of precision electronic devices are used and networked, but lightning rods are unable to protect these electronic devices. In view of this problem, relevant professional departments are needed to provide technical support for the lightning protection work in our park.

Summary of lightning protection work 5 First of all, I would like to extend a warm welcome to the leaders who came to our county to inspect and guide the work. Our county has always attached great importance to lightning protection safety, arranged and deployed according to the unified lightning protection safety work of the municipal party committee and the municipal government, strengthened organizational leadership, implemented management responsibilities, solidly carried out all lightning protection safety work, comprehensively promoted the construction of lightning protection standardization, and ensured the lightning protection safety of the people. Below, make a brief report on the lightning protection safety work in 20xx.

First, earnestly strengthen the organization and leadership of lightning protection and safety work.

In order to effectively implement the lightning protection work, our county brought the lightning protection and disaster reduction work into the scope of safety production supervision and management, and held several meetings to analyze the lightning protection safety situation. In view of the existing problems and deficiencies, the lightning protection safety management work is scientifically and reasonably deployed to ensure that the lightning protection safety work is always under the effective management of the county party Committee and the government. At the same time, the responsibilities of meteorological, safety supervision, quality supervision, housing and construction departments, industry and commerce and other relevant departments were clarified, and a lightning protection safety management mechanism was formed, which effectively promoted the smooth development of lightning protection safety management. In the case of very difficult county finance, 30,000 yuan of lightning protection funds were still implemented, and lightning protection and disaster reduction funds were included in the fiscal budget at the corresponding level.

Two, standardize and improve the meteorological administrative examination and approval process.

Lightning protection device drawing review and completion acceptance are included in the administrative licensing approval process, and lightning protection device drawing review and completion acceptance of real estate projects, county fixed assets investment projects are included in the administrative licensing liaison office process. The catalogue and flow chart of administrative licensing authority are published to the public on the Lixian government information website. Administrative licensing matters have all been incorporated into the administrative service hall. Up to now, * * * has participated in 10 joint reconnaissance project and 2 1 joint scheme review project, and accepted 2 1 lightning protection device design review project.

The third is to carry out a special inspection of lightning protection safety.

20xx in late March, organized meteorological, safety supervision, public security, fire protection and other departments to carry out a lightning protection safety inspection, conducted a safety inspection of lightning protection facilities in inflammable and explosive places, communication power supply and crowded places in the county, and all of them formed written inspection reports, issued certificates of lightning protection facilities to qualified units, and issued rectification opinions to units with potential safety hazards, requiring them to rectify and re-test within a time limit. 20xx 10 to 1 10, the second lightning detection was carried out for dangerous enterprises such as gas stations, and more than 50 inflammable and explosive enterprises such as liquid ammonia, chemical industry, liquefied gas stations and gas stations were inspected, and the lightning detection coverage rate reached 100%. Issue a notice of rectification within a time limit for enterprises with lightning protection safety hazards, and urge relevant enterprises to carry out rectification as required. At the same time, strictly implement the monthly inspection system of key hazard sources, and establish and improve the county's lightning protection safety production management ledger. There was no serious lightning disaster in the supervision enterprise of Lixian county at 20xx degree.

Fourth, increase the propaganda of lightning protection science.

In combination with activities such as "323 Meteorological Day", "5 12 Disaster Prevention and Mitigation Day", "Safe Production Month" and "124 Legal Publicity Day", various forms such as radio, television, SMS, plain paper, banners, etc. were used to widely publicize laws and regulations on lightning protection and mitigation, common sense of disaster handling, and investigation and management of hidden dangers. Organize meteorological departments to go deep into rural areas, carry out lightning protection science knowledge activities in rural areas, explain the common sense of lightning protection and risk avoidance to the public, and distribute more than 0/000 copies of lightning protection and disaster reduction science materials. Through extensive publicity, the awareness of lightning protection and disaster reduction in society has been improved and the public's lightning protection and disaster reduction ability has been enhanced.

Five, strengthen the lightning disaster emergency capacity building.

According to the Management Measures for Lightning Protection and Disaster Reduction in Hebei Province, combined with the actual situation of our county, the emergency plan for lightning disaster was revised and improved. Emergency drills for lightning disasters were organized, which improved the level of disaster response. Give full play to the role of township meteorological information service stations and meteorological information officers, and investigate and count lightning disasters in various places through multiple channels. According to the severity of the disaster, organize relevant departments to quickly start the lightning disaster emergency plan to minimize the lightning disaster. In 20xx years, although our county has made some achievements in lightning protection safety production and the public's awareness of lightning protection safety has been greatly improved, there is still a gap with the requirements of superiors. In the future work, we will take this assessment as an opportunity to further intensify our work, improve our work measures, and constantly push the lightning protection work to a new level.

Summary of lightning protection work: In June and July, there was continuous heavy rainfall and lightning and windy weather in our city. In order to ensure the safe broadcasting of our radio and television in disastrous weather, the whole station cooperated with each other, and established a radio and television safety leading organization under the command of the director and deputy director, implemented strict and meticulous preventive measures and emergency plans, and the production and broadcasting departments actively responded, and quickly formulated specific safe broadcasting countermeasures in combination with the actual work, and strictly controlled the safe broadcasting.

First, strictly implement the emergency plan

In order to cope with the bad weather, our station issued the Emergency Plan and Emergency Handling Process for Safe Broadcasting of Radio and Television in Severe Weather such as Heavy Rainfall, Thunderstorm and Strong Wind. The production and broadcasting department immediately organized all the staff to study deeply, demanding to keep a clear head at all times, tighten the string of safety, and strictly follow the emergency plan and emergency handling process to ensure safe broadcasting.

Second, prepare in advance to ensure safety.

It is an important task for us to broadcast the strong lightning storm safely in advance and eliminate all possible safety hazards in the bud. Before entering the flood season, the production and broadcasting department, under the leadership of the director in charge, assisted the technical department to complete the installation and debugging of lightning protection devices for all the equipment and circuits of the production and broadcasting network as early as early as June, putting on a layer of "safety armor" for all the equipment, making it planned and implemented in advance, effectively ensuring that the equipment of our station is not damaged by strong lightning and heavy rain, and laying a solid foundation for our station to realize safe broadcasting in bad weather.

Third, rapid response and rapid disposal.

In the daily patrol, weekly inspection and daily broadcast control of the equipment, when hidden dangers and problems are found, the staff of the production and broadcast department will report to the relevant person in charge as soon as possible according to the plan and process, and deal with them quickly to ensure the broadcast safety.

Jin Yang, an employee of the production and broadcasting department, found UPS feeding during the broadcast control inspection and reported to the department head and the competent leader immediately. The competent leader led the heads of the production and broadcasting department and the technical department to the scene immediately for detailed investigation and emergency repair, and then the normal power supply was quickly restored, avoiding the possibility of a major failure of the whole station caused by UPS power failure.

Fourth, pay attention to dedication and stick to your post.

In July, the production and broadcasting department, especially the broadcasting control station, was temporarily understaffed due to the reorganization of the department and office. In this case, the staff overcame difficulties, emphasized unity and the overall situation, gave up normal rest time and took care of their families, and insisted on double posts. Especially in the continuous bad weather, comrades with women and children can't take care of their own safety, and new mothers can't breastfeed their children. They take the wind and rain as their home, and guarantee the broadcast safety of our station with the dedication of pure radio and television people.
