Why are there no grounding wires in rural areas? Why is there no grounding wire for electricity in r

Reasons for not grounding wires in rural areas:

In rural areas, single-phase lighting electricity is generally used. Basically, there is no grounding wire. The wiring is not very standardized. You can make your own one. Choose the first flat iron as the grounding pile, and weld a grounding body by yourself.

The grounding body is very important, when choosing the piling area, it is necessary to choose a place where few people and animals move around, and carefully check whether there is looseness or poor contact after welding, if there is, it needs to be repaired immediately, otherwise once it causes leakage, the consequences are unimaginable.

After the grounding body is made, a steel bar is welded to the grounding body and buried on the ground. Finally, a wire is soldered on the steel bar protruding from the ground and connected to the room, which is the ground wire of the self-built house in the countryside.

Generally speaking, rural self-built houses should also be grounded, and because rural self-built houses are built by themselves and have not undergone formal acceptance, many times people directly omit the grounding wire. The installation of ground wires in the city's houses is mandatory, otherwise it cannot pass the acceptance.

This is because the rural electrical installation is not standardized, and the buildings in the city generally have drawings after verification, and there is supervision and supervision in the construction, and there are all aspects of acceptance after the completion of the house, so these buildings have grounding wires.

On the other hand, the concept of safety is weak, and some do not understand the safety of electricity.

The function of the ground wire: a wire that can introduce an electric current into the ground. When electrical equipment leaks or the voltage is too high, the current can enter the ground through the ground wire. Avoid the occurrence of leakage accidents.

Rural areas are mainly not concentrated, the cost of grounding connection is too high, rural areas are generally ordinary lighting, household appliances rarely use grounding electrodes. If it is really necessary, it is recommended that a single household make a grounding device on the spot.

If there is no leakage protector at the transformer, you can make a grounding drill at the entrance to the house, connect the power neutral wire to the drill, and lead out a ground wire. If there is a leakage protector at the transformer, the neutral wire cannot be connected to the grounding drill.

Grounding method composition.

1) Grounding body: a conductor or group of conductors that are in close contact with the earth and form an electrical connection with the earth.

2) Exposed conductive part: the conductive part that can be reached by electrical equipment. It is not energized during normal times, but may be energized when it fails, and it is usually a metal casing for electrical equipment.

3) Main grounding terminal board: a combination of terminals of various grounding (such as working grounding, protective grounding) and terminals of equipotential connection wires in a building or part of a building. If arranged in rows, it is called a main ground terminal strip.

4) Protection wire (PE): the conductor that electrically connects the above-mentioned exposed conductive part, the main grounding terminal board, the grounding body and any part of the power grounding point (or artificial grounding point). For conductors that connect multiple exposed conductive sections, they are called protective trunks.

Most of the electricity used in rural households is not grounded, and the grounding wire is not arranged when the house is built, in fact, the household power supply is not necessary to install the grounding wire.

As long as the main switch into the house has a leakage protection function, even if there is leakage or personal shock, the leakage switch will trip in time.

The power grid should pull a ground wire, and the cost should be borne by the power grid company.

Rural areas do not have a good sense of safety, coupled with the grounding wire and invest a sum of money, many rural families feel that 220V wires do not need to be grounded, be careful and have nothing to wait for luck, are not willing to spend another amount of money.

1. It is definitely wrong to say that there is no grounding wire for rural wires. It's just that there was no grounding wire for the entrance line before, and the main circuit such as transformer still exists.

The grounding wire can be buried 1 meter deep in the ground with a meter-long hot-dip galvanized angle steel, and then a wire is drawn from this angle steel, which is the ground wire. It is best not to share the grounding point with the electrical grounding, but to set the grounding point separately.

You can insert a ground wire into the ground on a metal skin appliance and you're good to go.

Of course, it is necessary to install a ground wire, and this installation of a ground wire is very good for thunder and rainy days, so this is actually a guarantee of safety, and I think it should be installed no matter when the ground wire should be installed.

In the Hubei chapter of the 2021 city rankings, Xiangyang and Jingzhou are both third-tier, why Jingmen is only.

In rural areas, due to historical reasons or hardware constraints, there are indeed some cases where there is no grounding wire holder. In this case, if you need a grounding wire, you can do so by creating a "fake" grounding wire. Hitting an iron into the ground is a common method, but there are a few things to keep in mind:

1.The length and depth of the striking iron should be sufficient: In order to ensure that the "fake" grounding wire can be effectively grounded, the length and depth of the striking iron need to be sufficient. As a rule, it is advisable to beat the iron above the depth of meters below the ground, with a length of between 2-3 meters.

2.Iron needs to be connected to the power supply equipment: Iron needs to be connected to the power supply equipment that needs to be grounded, so that the leakage current of the electrical appliance can be effectively channeled into the ground.

3.Check the grounding effect: Once the iron is laid and connected to the power supply equipment, you need to check whether the grounding effect is good. Testing can be performed using tools such as a multimeter to ensure that the ground resistance value meets the specifications.

It should be noted that this "fake" grounding wire is not as effective as the formal grounding wire, so it is recommended to install the formal grounding wire as much as possible to ensure the safe use of electrical appliances when conditions permit.

Here's the correct grounding wire method, I hope it will be useful to you:

1. First of all, you must choose the best flat iron as the grounding pile and weld it yourself'm next to a grounding body, it is very important to pay attention to the grounding body, when choosing the piling area, to choose a place where few people and animals walk around.

2. After welding, carefully check whether there is loose or poor contact, if there is, it needs to be repaired immediately, otherwise once it causes leakage, the consequences are unimaginable.

3. After the grounding body is made, weld a steel bar on the grounding body, and stick out of the ground for about 1 meter, and bury it.

4. Soldering a 4 square millimeter wire on the steel bar protruding from the ground and connecting it to the room, which is the ground wire of the self-built house.
