Tips on using electricity

1. Common sense and application of electricity

1. Why must the lighting switch be connected to the live wire? If the lighting switch is installed on the neutral line, although the light does not light up when it is turned off, the phase line of the lamp head is still connected, and people think that the light does not light up, and they mistakenly think that it is in a power outage state.

In fact, the voltage to ground at each point on the lamp is still a dangerous voltage of 220 volts. If people touch these actually live parts when the lights are off, it will cause an electric shock accident.

Therefore, the safety of various lighting switches or switches of single-phase small-capacity electrical equipment can only be ensured if they are connected in series on the live wire. 2. How to install a single-phase three-hole socket correctly? Why? Generally, single-phase electrical equipment, especially mobile electrical equipment, should use three-core plugs and matching three-hole sockets.

There is a dedicated protective zero (ground) jack on the three-hole socket. When using zero protection, some people often only connect the plug head of this hole in the bottom of the socket with the one introduced into the socket. The neutral wire is directly connected, which is extremely dangerous. Because if the neutral wire of the power supply is disconnected, or the live (phase) wire and neutral wire of the power supply are connected reversely, the metal parts such as the casing will also carry the same voltage as the power supply, which will cause electric shock.

Therefore, the dedicated grounding jack should be connected to the dedicated protective grounding wire when wiring. When using zero connection protection, the neutral wire should be specially led from the power supply end instead of using the neutral wire introduced into the nearby socket.

3. Why is it strictly forbidden to bury plastic insulated wires directly in the wall? (1) After long-term use of plastic insulated wires, the plastic will age and crack, and the insulation level will be greatly reduced. When the line is overloaded or short-circuited for a short time, it is easier to accelerate the damage of the insulation. (2) Once the wall gets damp, it will cause large-area leakage and endanger personal safety.

(3) Plastic insulated wires are directly buried, which is not conducive to line inspection and maintenance. 4. Why use leakage protector? The leakage protector, also known as the leakage protection switch, is a new type of electrical safety device. Its main uses are: (1) Preventing electric shock accidents caused by leakage of electrical equipment and electrical lines.

(2) Prevent single-phase electric shock accidents during electricity use. (3) Timely cut off single-phase ground faults during the operation of electrical equipment to prevent electrical fire accidents caused by leakage.

(4) With the improvement of people’s living standards and the continuous increase of household appliances, in the process of using electricity, personal electric shock and accidents are caused due to defects in the electrical equipment itself, improper use and unfavorable safety technical measures. Fire accidents have brought undue losses to people's lives and property, and the emergence of leakage protectors has provided reliable and effective technology to prevent the occurrence of various accidents, cut off the power supply in time, and protect equipment and personal safety. means. 5. What are the main causes of electric shock accidents? Statistics show that the main reasons for electric shock accidents are as follows: (1) Lack of electrical safety knowledge, flying kites near high-voltage lines, climbing high-voltage poles to dig out bird's nests; and picking up low-voltage overhead lines by hand without power outage after they are disconnected. Live wire; touch the live parts with your hands during live wiring at night; touch the damaged rubber cover of the knife switch with your hands.

(2) Violating operating procedures, connecting lines or electrical equipment while live without taking necessary safety measures; touching damaged equipment or wires; mistakenly boarding live equipment; connecting lighting fixtures while live; repairing power tools while live ; Live mobile electrical equipment; Use wet hands to twist light bulbs, etc. (3) The equipment is unqualified and the safety distance is not enough; the grounding resistance of the two-wire-one-ground system is too large; the grounding wire is unqualified or disconnected; the insulation-damaged conductor is left outside etc.

(4) The equipment is in disrepair, and strong winds cut off the lines or knocked down the poles and they were not repaired in time; the bakelite of the rubber cover knife gate was damaged and was not changed in time; the wires of the motor were damaged, leaving the casing charged for a long time; the porcelain bottle was damaged, causing the The phase wire and the pull wire are short-circuited, and the equipment shell is charged. (5) Other accidental reasons, such as walking at night and touching live wires that fell to the ground.

6. What rescue measures should be taken in case of electric shock? When an electric shock accident occurs, while ensuring the safety of the rescuer himself, he must first try to quickly remove the electric shock victim from the power supply, and then carry out the following emergency repair work. (1) Remove tight clothing that hinders the electrocuted person’s breathing.

(2) Check the mouth of the person who received an electric shock, clean the mucus in the mouth, and remove dentures if there are any. (3) Immediately carry out rescue on the spot. If breathing stops, use mouth-to-mouth artificial respiration. If the heart stops beating or trembles irregularly, artificial chest compression can be used.

Never interrupt without reason. If there is a second person present at the scene in addition to the rescuer, the following work should be carried out immediately: 1) Provide first aid tools and equipment.

2) Dissuade idle personnel from the scene. 3) Keep the site with adequate lighting and air circulation.

4) Report to the leader and ask a doctor to come for rescue. Experimental research and statistics show that if the rescue begins 1 minute after the electric shock, 90% of the people can be saved; if the rescue starts 6 minutes after the electric shock, there is only a 10% chance of survival; and if the rescue starts 12 minutes after the electric shock, 90% of the people can be saved. The possibility of survival is extremely small.

Therefore, when you find someone getting electrocuted, you should race against time and use all possible methods. 7. What measures can be taken to safely use electricity at home? With the popularization of household appliances, it is crucial to correctly grasp the knowledge of safe electricity use and ensure the safety of electricity use.

(1) Do not buy fake and shoddy household products with "three noes". (2) When using home appliances, there should be a complete and reliable power cord plug.

Household appliances with metal casings must be grounded for protection. (3) Switches and fuses cannot be installed on the ground wire and neutral wire.

It is prohibited to connect the ground wire to tap water or gas pipes. (4) Do not touch live equipment with wet hands, and do not wipe live equipment with wet cloth.

(5) Do not connect wires indiscriminately and do not move live equipment casually. (6) When inspecting and repairing household appliances, the power supply must be disconnected first.

(7) When the power cord of a household appliance is damaged, it must be replaced immediately or wrapped with insulating cloth. (8) When a fire breaks out in household appliances or wires, disconnect the power supply first and then put out the fire.

8. How to prevent household appliances from burning? The rated voltage of commonly used household appliances is 220 volts, and the normal power supply voltage is around 220 volts. The voltage rise occurs when the power supply voltage in the power supply line rises instantaneously due to natural disasters such as lightning strikes, the three-phase load is unbalanced and the household line is in disrepair for a long time and the neutral line is broken, or the phase voltage rises due to human miswiring, etc. , which will increase the current and cause household appliances to burn out due to overheating.

To prevent burning of household appliances, we must start from the following aspects: First, when the electrical equipment is not in use.

2. What are the common sense about safe use of electricity in life?

Common sense about safe use of electricity in life 1. Instructions for safe use of electricity: 1. Do not overload electricity.

Large-capacity electrical equipment such as air conditioners and ovens should use dedicated lines. 2. Choose qualified electrical appliances, and do not buy or use fake and inferior electrical appliances, wires, trunking (troughs), switches, plugs, sockets, etc. for cheap.

3. Do not lay wires and connect electrical equipment privately or hire unqualified decoration teams and personnel. Only qualified units and personnel are required to install and repair electrical appliances. 4. The metal casing of electrical appliances that are required to be grounded must be protected from grounding. Don't forget to install a grounding wire for the three-pin socket, and do not change the three-pin plug into a two-pin plug at will.

5. Choose a fuse that is suitable for the load of the wire. Do not make the fuse arbitrarily thick. It is strictly forbidden to use copper wire instead of the fuse. 6. Do not wipe live lamp holders, switches and sockets with wet hands or wet cloth.

7. Conduct sensitivity tests on leakage protection switches regularly. 8. Keep a safe distance between the clothes drying rack and power lines, and do not place the clothes drying pole on the power lines.

2. How to prevent common electrical accidents 1. Do not pull or connect wires randomly.

2. When replacing fuses, dismantling or repairing electrical appliances or moving electrical equipment, the power supply must be cut off, and do not risk operating with power on.

3. Do not leave when using household electric heaters such as electric irons, hair dryers, and electric stoves. 4. When no one is in the room, the water dispenser should be turned off.

5. When you find smoke or smell from electrical equipment, quickly cut off the power supply for inspection. 6. Clothes cannot be baked on electric heating equipment.

7. Take care of electrical facilities and do not fly kites near overhead wires and distribution transformers. 3. How to deal with electric shock accidents in an emergency 1. Get the person who gets an electric shock out of the power supply quickly.

Immediately pull down the power switch or unplug the power plug. If the power cannot be found or disconnected in time, dry bamboo poles, wooden sticks and other insulating materials can be used to open the wires.

2. Move the person who is out of power and get an electric shock quickly to a ventilated and dry place, lie on his back, and loosen his shirt and trousers. 3. Perform first aid, call an ambulance in time, and send the patient to the hospital for rescue as soon as possible.

3. Tips for saving electricity

1. TV When you use a TV, whether it is a color TV or a black and white TV, without affecting the audio and visual, Don’t turn the brightness too bright and keep the volume as low as possible.

In addition, do not switch on and off frequently. For some remote control color TVs without AC shutdown function, the remote control receiving part is still charged after shutting down, and the indicator light is on. This will consume some power. You should unplug the power plug after shutting down. . 2. Power amplifier The main way to save power is to reduce the volume. The impedance of the external speaker should not be too small.

Avoid using multiple speakers in open connection and reduce the load on the power amplifier as much as possible to save power and protect the machine. 3. Refrigerator: Be careful not to push the food in the refrigerator too full or too densely, otherwise it will hinder the circulation of cold air and cause the refrigerator to not cool.

It is not advisable to store too little food in the refrigerator. If there is too little food in the refrigerator, air conditioning will be lost and electricity will be wasted. Refrigerators should try to reduce the number of times and the time they open the door. Except for frost-free refrigerators, they should be defrosted in time.

Pay special attention to regularly dusting the condenser to avoid affecting the cooling effect and wasting electricity. 4. Washing machine Clothes should be washed as concentratedly as possible.

The amount of laundry in the washing tub should be close to the maximum washing capacity to reduce the number of times of washing and improve work efficiency. If the washing machine has been used for more than 3 years and finds that washing is ineffective, the motor belt of the washing machine should be replaced or adjusted to make it appropriately tight.

Every once in a while, lubricating oil should be added to the place where the washing machine needs to be refueled to ensure good operation and achieve the purpose of saving energy. 5. Electric rice cooker: The electric rice cooker is an electric cooking appliance that consumes a lot of power.

Due to its excellent heat preservation performance, when cooking food with a rice cooker, when the water in the pot boils, the power can be cut off and the residual heat can be used to heat the food for a period of time. If the rice is not cooked through, you can turn on the power again.

In this way, intermittent power supply can save about 20 to 30 yuan of electricity. 6. Electric iron: When using an electric iron, you should iron the clothes as much as possible and select the corresponding temperature control point according to different clothing materials.

If you are using an ordinary electric iron that cannot adjust the temperature, you must also control the temperature and cut off the power immediately when it reaches the temperature required for the fabric. If heat preservation is required, a 3A, 400V rectifier diode can be connected in parallel to the switch. When the switch is turned on, normal heating occurs; when the switch is turned off, the rectifier diode is connected in series to the circuit and enters the heat preservation state.

The electric iron can save about 40% of electricity when kept warm. 7. Electric fan The power consumption of the electric fan motor is approximately proportional to the load size (that is, the size of the electric fan blades) and the voltage applied to the motor. The voltage applied to the motor is approximately proportional to the speed.

In other words, the larger the blade diameter, the higher the rotation speed, and the greater the power consumption. Under the condition that the air volume is basically met, an electric fan with a smaller blade diameter should be used as much as possible.

The electric fan should be started at a high speed, and then switched to a medium or low speed after reaching the rated speed. This will help the motor start at a faster speed, thus achieving the purpose of saving power and protecting the motor.

8. Lighting fixtures Lighting fixtures used in homes should be as high-brightness, low-power, and energy-saving as possible.

The energy-saving lamps currently promoted can generally save about 20 to 70 yuan of electricity. However, you must use qualified high-quality energy-saving lamps produced by regular manufacturers, and do not be greedy for cheap, so as not to cause unnecessary losses to yourself.

Existing incandescent lamps in the home (including chandeliers, wall lamps, continuous lamps, etc.). If high brightness is not required, a rectifier diode can be connected in series to the circuit (for 100 watts or less, 1 A, 400 volts is optional; for 100 watts or 300 watts, 2 amps, 400 volts is optional), which can save about 40% of electricity.

4. What is the knowledge about safe use of electricity?

With the continuous improvement of living standards, more and more places use electricity in life. Therefore, it is necessary to master the following The most basic common sense of safe electricity use: 1. Understand the main power switch and learn to turn off the main power supply in an emergency. 2. Do not touch or test the power supply with hands or conductive objects (such as wire, nails, pins and other metal products) Inside the socket. 3. Do not touch electrical appliances with wet hands or wipe them with wet cloth. 4. Unplug electrical appliances after use; do not pull the wires hard when plugging or unplugging the power plug to prevent damage to the insulation layer of the wires and cause electric shock; If the insulation of a wire peels off, replace it with a new one in time or wrap it with insulating tape. 5. If you find someone getting an electric shock, try to turn off the power supply immediately; or use dry wooden sticks or other objects to separate the person who got the electric shock from the live electrical appliance. Do not use your hands. Go and rescue people directly; when younger students encounter this kind of situation, they should call for help from adults and do not handle it by themselves to prevent electric shock. 6. Do not disassemble or install power lines, sockets, plugs, etc. at will. Even if it is simple to install light bulbs, etc. When doing any work, you should also turn off the power first and do it under the guidance of parents. Nowadays, more and more household appliances such as televisions, refrigerators, washing machines, electric irons, hair dryers, and electric fans have entered the family. Use household appliances In addition to paying attention to the safe use of electricity, you should also pay attention to the following points: 1. Various household appliances have different uses and different methods of use, and some are more complicated. General household appliances should be learned and used under the guidance of parents. Do not use electrical appliances that are more dangerous by yourself. 2. If you find that the electrical appliance is emitting smoke, sparks, or a burnt smell during use, you should turn off the power switch immediately and stop using it. 3. Hair dryers, rice cookers, etc. Electrical appliances such as pots, electric irons, and electric heaters will emit high heat during use. Care should be taken to keep them away from flammable items such as paper and cotton to prevent fires. At the same time, pay attention to avoid burns when using them. 4. Avoid using them in humid places When using electrical appliances in an environment (such as the bathroom), do not let the appliances get wet or damp. This will not only damage the appliances, but also cause the risk of electric shock. 5. The blades of electric fans and the dehydration drum of washing machines rotate at high speed when working. , do not touch it with hands or other objects to prevent injury. 6. When encountering thunderstorms, stop using the TV and unplug the outdoor antenna to prevent lightning strikes. 7. Electrical appliances are left unused for a long time and are susceptible to moisture and corrosion. If it is damaged, it needs to be carefully inspected before reuse. 8. When purchasing household appliances, choose qualified products with reliable quality.
