First, how to do the socket ground wire?
Most rural users choose to live directly in a room without a ground wire, because they don't know the function of the ground wire, and they don't know that the ground wire is actually a lifeline. The following materials we need for grounding wire: 40x40x4 (side width x side width x side thickness) 3 hot-dip galvanized angle steel (hot-dip galvanized is required, cold galvanized is not accepted), each1.5m; 40x4 (width x thickness) hot-dip galvanized flat steel 6m 1+ 1m 1, * * * 2; Raw salt10 ~ 20kg; /kloc-a number of copper armored wires over 0/.5 square mm (as ground wires, they should be pulled indoors, and the length should be measured according to the actual distance). The following tools are also needed: digging tools (shovel, hoe, etc. ); Electric welding tools (electric welding machine, solder, etc. ); Wiring tools (wire stripper, etc.). ). The specific methods are as follows:
1, dig a hole. Dig a hole at least 2.5 meters away from the wall. The depth of the pit is 2.3~2.5 meters, and the width is not required. You can put an angle steel in it (dig wider, otherwise there will be trouble during construction). The pit length is not less than 6 meters.
2. Put the angle steel. Sprinkle salt in the pit. The purpose of spreading salt is to reduce the resistivity of soil. If there is no salt, use charcoal or pure water. After that, put the angle steel vertically in the into the pit (it must be vertical), and the distance between each angle steel is 3m, and fix it. After placing angle steel, the upper end of angle steel should be 0.8~ 1 m from the ground.
3. welding. Put the flat steel on the angle steel and weld it with each angle steel. Is it a mouth down after welding is completed? Mountain? Words. After the welding is completed, our grounding body is basically completed.
4. wiring. Give me the wire. Where is it? Mountain? The flat steel corresponding to the vertical line in the middle of the Chinese character is perforated and connected, or directly welded on the flat steel.
5. lead wire. The wire at this time is the ground wire. Lead this wire into the distribution box and connect it to the floor of the distribution box. In this way, the ground wire can be led out from the floor panel and connected to all the sockets in the home. Remind that the wire used at this time is armored wire, not the wire we usually use for decoration, and can be directly buried underground.
Second, what is the role of the ground wire?
1, protect personal safety
Because electrostatic discharge is easy to produce a lot of charge, if the electrical equipment is improperly isolated, it will easily cause great harm to electricity itself and human body. The function of grounding wire is only to become a high-voltage device, and the wire is grounded to prevent us from being damaged by charging.
2. Lightning protection law
In the past, in thunderstorm weather, telephone poles and other equipment were often damaged by lightning, and sometimes they could not be used for several days. Therefore, the role of grounding wire in lightning protection can be well protected and the service life of electrical equipment can be effectively prolonged.
3. Ensure normal operation.
For some work that must be electrified, such as medical work, the role of grounding wire is to avoid sudden power failure, so that it can still work normally without being affected.
Third, how to connect the ground wire?
1, standard operation
Buy high-quality flat iron (above 1M, above 30MM thick, corrosion-resistant steel) or similar materials as grounding piles to better play the role of grounding wire. In addition, pay attention to the selection of pile area. There are people and animals moving around to build, so it is recommended to use welding to operate. After welding, carefully check whether there is looseness or poor contact, and repair it immediately if there is any. Otherwise, once a leak occurs, the consequences will be unimaginable.
Step 2 add a shell
The shell plays an important role in grounding the ground wire, so if you want to use electricity more safely, you may wish to consider adding shell appliances through high-quality and compact plastic pipes and then grounding, but don't use gas pipes or materials that others can touch as grounding piles.
3. Qualified plugs and sockets
If you want to achieve the function of strong power protection, you can install qualified high-quality plug and socket cables at home and establish a complete grounding protection system.
The above is an introduction about how to make socket ground wire. If you want to make your own ground wire, you must pay attention to preparing the required related materials and follow the above steps. If you don't understand, you can also consult a professional. Pay attention to standard operation when carrying grounding wire to ensure no leakage in the future.
