9. Fishing, theft prevention and hunting in private power grids are prohibited.
10. It is forbidden to use lead wire and copper wire instead of fuse as fuse. Wait a minute.
2. What safety matters should be paid special attention to when using electricity in rural households?
Pay special attention to the following safety matters when using electricity in rural households: 1. When building a new house or rebuilding an old house, people who don't know electricity should not lay wires casually. They should ask an electrician to help with the design and construction, which is cost-effective.
Because whether the electrical wiring is reasonable or not and how the installation quality is, it has a great relationship with the safety of electricity use in the future. When building a new house, be sure to pay attention to whether the house is too close to the power line or substation.
If the distance is not enough, find the power department, and don't rush to build it, otherwise it will cause electric shock casualties. 3. In some areas, the economic conditions are good, and many household appliances are laid by hidden wires.
The hidden wire is beautifully laid, but it is not easy to repair if something goes wrong, so it must be constructed in strict accordance with the regulations. At present, the common practice is to use plastic sheath line or even plastic wire to lay in the paint layer; Also, some wires or rubber cables on it are directly buried in brick walls or cement layers.
These practices are all wrong. Especially when wires or rubber cables are burnt out due to mechanical damage or large electricity consumption, the walls of the whole house may be charged, and it is almost impossible to find out the fault point because they are buried underground.
Improper handling of short circuit or leakage fault may lead to electric shock or fire accident. 4. Don't use nuts, because the screws of nuts are used as electrodes. At present, in some rural areas, the management of electricity consumption is not strict, and the screw of the screw cap is likely to be connected to the phase line (although it was connected to the zero line at that time, the phase line and the zero line may be exchanged when the external inspection modifies the bending line). When changing the light bulb or cleaning, it is easy to touch the screw, causing electric shock casualties.
Therefore, in rural areas, bayonet bulbs should be used instead of spiral bulbs. In recent years, household appliances have become popular in rural areas. Because rural residents often work in the fields, barefoot and wet hands are more common. At the same time, rural houses are mostly made of mud, cement and bricks, which are widely used, so the possibility and severity of electric shock are greater.
Therefore, when using household appliances, we should not be careless and avoid touching household appliances with bare feet and wet hands. Don't play around without knowing the performance and usage requirements of a household appliance.
6. Electric shock casualties caused by electric fan leakage are particularly prominent in rural areas. You should consult people who know how to use it and use it carefully. 7. It is very common to use waste or damaged wires as power lines in rural areas, especially for temporary electricity use.
When it is used, it is not carefully checked, and the wires of * * * are not wrapped properly, so once the human body touches them, it will get an electric shock. Improper handling of wire connectors used in outdoor venues. In the past, wire connectors have been wrapped in black tape. Because the black tape loses its insulation effect after being wet or raining, or deteriorates or falls off due to time, people often touch this kind of wire connector and get an electric shock.
At the same time, if there are haystacks and firewood under the conductor, it will cause a fire in case of short circuit of the conductor. Therefore, it is suggested that the joints of temporary power cables hanging low or mopping the floor outdoors and in the yard should be wrapped with plastic tape with good viscosity and flexibility.
8. Motor is a common electrical equipment for rural residents. Common unsafe factors are: the lead wire at the entrance and exit of switch box and junction box, and the lead wire at the box mouth is twisted or broken, which leads to charging or short circuit of the shell. Therefore, the import and export ends of wires should be padded with elastic buffer layers; Sheath rubber must be embedded in the box mouth to prevent the port from leaking.
9. Threshers and submersible pumps used in the yard or field are also electrical equipment that cause more electric shock and fire accidents. Try to understand the safe use points of two kinds of electrical equipment, and don't move.
10。 When TV sets are used in rural areas, outdoor antennas are often set up because they are far away from TV stations and receive weak signals.
However, rural houses are scattered, mostly built in the wild, and TV antennas stand out from the ground in isolation, which is easy to be struck by lightning in thunderstorm season. Therefore, families with conditions should install lightning protection devices according to the specifications; Families without conditions should unplug the antenna feeder and throw it outside the thunderstorm, unplug the power supply and stop watching.
1 1。 The accident of electrocution caused by step voltage has been more prominent in rural areas. Most of the causes of electric shock accidents caused by step voltage are the disconnection. People who get electric shock lack safety knowledge and want to pick them up with their hands or fish duckweed in the paddy field near the disconnection.
3. What should we pay attention to when using electricity safely in rural areas?
1. Apply for electricity first and find an electrician for installation and maintenance. Illegal operation and unlicensed operation are prohibited.
2. Every user should consciously abide by the rules and regulations for safe use of electricity;
3. It is forbidden to build houses, drill wells, plant trees and pile firewood under power lines;
4. No quarrying or blasting near the power line;
5. Don't dig a hole near the pole for earth, and don't destroy the stay wire to prevent the pole from falling and breaking;
6. Power lines, communication lines and broadcasting lines should be clearly set separately. The iron wire and iron wire for drying clothes should be kept at a sufficient distance, and they should not be entangled together, let alone dry clothes on the iron wire;
7. Educate children not to play with electrical appliances, not to climb poles, not to climb substations and not to shake cables;
8. Don't fly kites or shoot birds near the wires;
9. Don't throw things on wires, porcelain bottles and transformers;
10. Stay away from the broken wire, assign personnel to guard it, and notify the electrician in time;
1 1. In household appliances, don't touch the metal shell of household appliances such as lamp holders and sockets with your hands. If there is any damage, aging or leakage, please find an electrician to repair or replace it quickly. The metal shell of household equipment should be reliably grounded;
12. If you find someone getting an electric shock, don't pull it by hand. You should quickly pull down the switch, disconnect the power supply, or open the wire with a dry bamboo pole, and immediately give first aid on the spot with correct artificial respiration or chest compressions instead of a shot in the arm.
4. What are the common household electrical safety knowledge?
L, know the master switch, learn to turn off the master switch in an emergency.
2. Don't touch and test the inside of the power socket with your hands or conductive objects (such as wire, nails, pins and other metal products).
3. Don't touch the appliance with wet hands or wipe it with wet cloth.
4, electrical appliances should be unplugged after use; Don't pull the wire when plugging and unplugging the power plug to prevent the insulation of the wire from being damaged and causing electric shock; The insulation layer of the wire is peeling off, so it is necessary to replace the wire in time or wrap it with insulating tape.
5, found someone get an electric shock to try to turn off the power in time; Or use dry wooden sticks and other things to separate the electric shock victim from the charged electrical appliances, and don't save people directly by hand; Younger students should ask adults for help in this situation, and don't handle it by themselves to prevent electric shock.
6. Don't remove or install the power cord, socket and plug at will. Even if it is as simple as installing a light bulb, it should be turned off first and carried out under the guidance of parents.
Don't think such a question is meaningless.
A lot of trouble is my own fault.

6. Common sense of household electricity use
1. Why does the lighting switch have to be connected to the live wire? If the lighting switch is installed on the zero line, although the light is not on when it is turned off, the phase line of the lamp holder is still on, and people will think that the light is not on and will mistakenly think that it is in a power-off state.
In fact, the ground voltage of each point on the lamp is still a dangerous voltage of 220 volts. If people touch these actually charged parts when turning off the lights, it will cause an electric shock accident.
Therefore, all kinds of lighting switches or switches of single-phase small-capacity electrical equipment can only be connected in series on the live line to ensure safety. 2. How to correctly install the single-phase three hole socket? Why? Usually, single-phase electrical equipment, especially mobile electrical equipment, should use three-core plug and its supporting three hole socket.
There is a special protective zero (grounding) jack in three hole socket. When using zero protection, it is very dangerous for someone to directly connect the wiring pile head of this hole with the zero line that only leads into the socket at the bottom of the socket. Because in case the zero line of the power supply is disconnected, or the fire (phase) line and the zero line of the power supply are connected reversely, its shell and other metal parts will also bring the same voltage as the power supply, resulting in electric shock.
Therefore, when wiring, the special grounding jack should be connected with the special protective grounding wire. When zero protection is adopted, the zero line should be led out from the power supply side, and the zero line introduced into the socket should not be used nearby.
3. Why is it forbidden to bury plastic insulated wires directly in the wall? (1) Plastic insulated conductor will age and crack after long-term use, and the insulation level will be greatly reduced. When the line is overloaded or short-circuited, it is easier to accelerate the insulation damage. (2) Once the wall is damp, it will cause a large area of leakage and endanger personal safety.
(3) Plastic insulated wires are directly buried, which is not conducive to line maintenance and repair. 4. Why should I use a leakage protector? Leakage protector, also known as leakage protection switch, is a new type of electrical safety device. Its main purpose is: (1) to prevent electric shock accidents caused by leakage of electrical equipment and electrical lines.
(2) To prevent single-phase electric shock accidents in the process of electricity utilization. (3) Cut off the single-phase grounding fault in the operation of electrical equipment in time to prevent electrical fire accidents caused by leakage.
(4) With the improvement of people's living standards, the number of household appliances is increasing. In the process of using electricity, personal electric shock and fire accidents caused by defects in electrical equipment, improper use and unfavorable safety technical measures have brought undue losses to people's lives and property. The appearance of leakage protector provides a reliable and effective technical means for preventing all kinds of accidents, cutting off power supply in time and protecting equipment and personal safety. 5. What is the main cause of electric shock accident? Statistics show that the main causes of electric shock accidents are: (1) lack of knowledge about electricity safety, flying kites near high-voltage lines and climbing high-voltage poles to dig nests; After the low-voltage overhead line is disconnected, connect the fire line by hand without power failure; Touch the charged body by hand for live wiring at night; Touch the broken rubber knife switch with your hand.
(two) in violation of the operating rules, without taking necessary safety measures, unauthorized connection of lines or electrical equipment; Touch damaged equipment or wires; Wrong installation of live equipment; Electrified lighting; Online maintenance of power tools; Live mobile electrical equipment; Twist a light bulb, etc with wet hands. (3) The equipment is unqualified and the safety distance is not enough; The grounding resistance of two-wire and one-ground system is too large; The grounding wire is unqualified or disconnected; Insulation damage to wires, etc.
(4) The equipment is in disrepair, the line is blown off by strong wind or the pole is not repaired in time; Rubber breaker bakelite is damaged and not replaced in time; The damage of the motor lead makes the shell charged for a long time; The porcelain bottle is damaged, which makes the phase wire and the pull wire short-circuited, and the equipment shell is charged. (5) Due to other accidental reasons, I walked at night and ran into a broken live wire on the ground.
6. What rescue measures should be taken in case of electric shock? When an electric shock accident occurs, while ensuring the rescuer's own safety, we must first try to make the electric shock victim quickly get rid of the power supply, and then carry out the following emergency repair work. (1) Untie the tight clothes that hinder the breathing of the electrocuted person.
(2) Check the mouth of the person who gets an electric shock and clean up the mucus in the mouth. If there are any dentures, remove them. (3) immediately on-site rescue. If breathing stops, rescue with mouth-to-mouth artificial respiration. If the heart stops beating or vibrates irregularly, use artificial chest compression to rescue it.
Never interrupt for no reason. If there is a second person besides the rescuer at the scene, the following work should be done immediately: 1) Provide first aid tools and equipment.
2) convince others at the scene. 3) Keep sufficient lighting and air circulation at the site.
4) Report to the leader and ask the doctor to come to the rescue. Experimental research and statistics show that 90% patients can be saved if treatment is started from 1 min after electric shock. Only 10% chance can save lives if rescue is started 6 minutes after electric shock; But from 12 minutes after electric shock, the possibility of saving lives is extremely small.
So if you find someone getting an electric shock, you should race against time and take all possible measures. 7. What measures are there to use electricity safely at home? With the popularization and application of household appliances, it is very important to correctly master the knowledge of safe electricity use and ensure the safety of electricity use.
(1) Don't buy fake and shoddy "three noes" household products. (2) When using household appliances, there should be a complete and reliable power cord plug.
Household appliances with metal shell should be protected by grounding. (3) Switches and fuses cannot be installed on the ground wire and zero wire.
It is forbidden to connect the ground wire to the tap water and gas pipeline. (4) Don't touch the live equipment with wet hands, and don't wipe the live equipment with wet cloth.
(5) Don't connect wires privately, and don't move live equipment casually. (6) When repairing household appliances, you must first disconnect the power supply.
(7) When the power cord of household appliances is damaged, it should be replaced immediately or wrapped with insulating cloth. (8) When household appliances or wires catch fire, disconnect the power supply first, and then put out the fire.
8. How to prevent burning household appliances? The rated voltage of common household appliances is 220 volts, and the normal power supply voltage is around 220 volts. If the power supply voltage in the power supply line rises instantly due to natural disasters such as lightning strike, the zero line of the three-phase unbalanced household line is broken due to years of disrepair, or the phase voltage rises due to human misconnection, the current will increase, and household appliances will burn out due to overheating.
To prevent the burning of household appliances, we should start from the following aspects: First, try to disconnect the power supply when the electrical equipment is not in use; The second is to transform the old and disrepair connecting lines; The third is to install with overvoltage.
7. What is the common sense of home safety electricity use?
Common sense of home safe electricity use: 1. If you want to install high-power household appliances (such as cabinet air conditioners, etc.). At home, you need to apply to the power supply department for installation and expansion first, and don't add appliances to the original line without permission.
Choose qualified electrical appliances, and don't use unqualified electrical appliances for the sake of cheapness. 3, in strict accordance with the capacity of electrical appliances to choose the appropriate conductor section, do not blindly increase electrical appliances, so that the conductor overload operation.
4. Select the fuse suitable for the conductor. Never replace the fuse with copper wire, aluminum wire or iron wire when it is blown. Instead, use fuses of the same specification and material. If it is still blown, then either there is something wrong with the electrical appliance, or there is something wrong with the line, or the load is too large. Solution: Don't use electrical appliances with high power consumption at the same time. 5. Control the incoming switch of phase line (also called live line), and "one line at a time" is not allowed.
6. The shell of household appliances that need to be grounded according to regulations should be well grounded. 7. Before replacing the fuse or repairing the electrical appliance, be sure to turn on the power switch, take safety protection measures, and don't risk live working.
8. The outdoor antenna of the TV set shall be installed firmly, and shall not be higher than the nearby lightning conductor or close to the high-voltage line. 9, electric iron, hair dryer, electric stove and other household appliances should be disconnected in time after use.
8. What are the common sense of rural electricity safety?
Common sense of rural electricity safety: don't build houses, pile firewood, drill fields, drill wells and plant trees under telephone poles, and don't perform or show movies near telephone poles and other live equipment to prevent electric shock and fire.
1. Measures should be taken when erecting derrick, repairing houses or cutting down trees near power lines. For the line equipment that may be encountered, find the power supply department after the power failure. 2. Don't whip the carriage when it passes through the power line; Don't touch the telephone poles and cables when the motor vehicle is driving or working in the wild.
3. Don't quarry or shoot near the electric wire, don't dig holes or borrow soil near the electric pole, don't dig fish ponds near the electric pole, don't tie animals to the electric pole, and don't destroy the stay wire to prevent the electric pole from falling down and the electric wire from being pulled off. 4. Power lines, communication lines and broadcasting lines should be clearly separated.
When the wire is found to be connected with other wires, it should be handled by the power supply department immediately. Keep enough distance between the iron wire and the line for drying clothes.
