1. Work grounding:

The working grounding is to bury the metal conductor copper block in the soil, and then lead its point out of the ground with a wire, and use it to complete the circuit to make the equipment meet the performance requirements of the grounding wire. The ground wire requires a ground resistance of 4. For example, in the sixties and seventies, every household in the countryside used a ground wire for broadcasting, and the grounding place had to be often wet with water.

2. Safety grounding

The electrical regulations stipulate that the protective grounding resistance should be 4, and the resistance of the human body is generally greater than 2000, according to Ohm's law, the current through the human body when the insulation is damaged is only 1 500 of the total current, and then play a protective role.

The metal shell of household appliances and office equipment is equipped with a grounding wire, if its insulation is damaged and the shell is electrified, the current will leak into the ground along the installed grounding wire to achieve the purpose of safety, otherwise it will cause harm to personal safety.

Do anti-theft barbed wire fences need to be fitted with grounding wires? I don't think it's necessary, because if the anti-theft barbed wire is electrified, the grounding wire needs to be installed, and if it is not electrified, there is no need to install the grounding wire.

This doesn't need it, it's just that it's energized on it, so you need to install a grounding wire.

Hello, friends anti-theft barbed wire is not required to install the ground wire there, because it is not electrified. It is better not to do such a thing, if it is dangerous in the case of electricity, you will be held legally responsible.

Under normal circumstances, the anti-theft barbed wire does not need to be installed with a ground wire, and if there is a condition, you can install it.

I think the anti-theft barbed wire probably needs to be installed with a grounding wire, because this thing may leak electricity if it is not grounded for safety reasons.

As far as I know, there should be no need to install a ground wire, and the installation of anti-theft barbed wire is actually relatively simple, and what we see is what it is.

If the anti-theft barbed wire fence is installed, but the installation base does not need to be grounded, it is useless, and the installation machine is useless.

Anti-theft barbed wire is not in a class. In general, a ground wire can be installed.

Anti-theft barbed wire does not need to be installed with a ground wire, because there is no electricity.

No, anti-theft barbed wire, he has no electricity, does not need to be installed offline.

Anti-theft barbed wire should also need to be installed with ground wires to avoid lightning.

If it is a power grid, it must be connected to a ground wire, and if it is not a power grid, it is not used.

Do anti-theft barbed wire fences need to be fitted with grounding wires? If you have an anti-theft barbed wire, it will be safer to connect to a ground wire.

: Requirements for the installation of the ground wire: the connection of the grounding device should be reliable, the place of unconditional welding, the welding of the grounding wire should be lap welded and the bolt crimping should be used when the grounding wire is connected with the electrical equipment. Correlation.

If you're not a team shop, you shouldn't need it.

You'd better find a professional to help you arrange it, so it's safe.

Do anti-theft barbed wire fences need to be fitted with grounding wires? I think it's supposed to be installed, right?,If you don't install it.,People who touch it will be electrocuted, right?

Do I need to install a ground wire when I first arrive at the barbed wire? I don't think it's better, why does he make a 3D line?

3. All in general, the selection of the protective grounding wire diameter of the actual equipment should be greater than or equal to the cross-sectional area corresponding to the rated current in the table.

The grounding wire used on the equipment is generally best to use copper core wire, preferably not less than 6 square meters, it is also iron wire, but it is very troublesome to use, you must do a good job of anti-rust treatment of iron wire, especially the connection points.

Indoor terrazzo floor, in the crack of the nail connected by the wire into the ground, can not be used as grounding, because its grounding resistance can not meet the requirements of the national standard, can not play a protective role.

It's not that there is a leakage, it's that your home's outlet doesn't have a grounding wire, and you can put your home's outlet grounded. Or you can attach a wire to the chassis, and then throw the other end of the iron on the ground.

Use a wire to connect one end to the chassis, and then connect the other end to the iron water pipe or connect to the iron anti-theft net, or you can nail a nail on the ground, connect the wire to the nail, the nail should be nailed a little deeper, and you can choose to nail it in the corner of the wall.

This mainly depends on whether there is a ground wire in the three wires of the power strip of your host's power supply, if there is, you don't need it.

Computer leakage is mainly induction, or static electricity, which is relatively common, do you know that there is a leakage protection switch installed at home? If you have, just connect your computer shell to the water pipe with a thicker wire, of course, it is best to check it first, the host plug should be three pins, and the socket should also be three pins, (the one above the three pins is dedicated to grounding), yes, but also leakage, that is, you do not install the ground wire when wiring at home, so you have to use the above method, the host can not be plugged in when the grounding wire, if the leakage switch at home trips, then you have to hand over a special person to check your computer, usually will not jump, after connecting, you are touching it, Your hands won't be numb. Hit into the wall, that's not called the ground wire, basically useless, the wire is connected to the screws on the host shell, to add,,The situation you said is not a real leakage,So it won't waste electricity.。

The real leakage will trip, of course, it can't be put on the ground, it's useless, and it's dangerous. Anti-theft nets are not reliable, and it is better to use a dedicated ground wire. (Electrician's opinion).

Cow man, dare to use the chassis leakage?

Let's change the chassis, hurry up!

What you said is directly connected to the floor, is it connected to the ** yo? The flooring of your house? Or the downstairs floor?

1.The line distance between the architectural lightning protection barrier used in the field and the sensor or transmitter to be protected must not exceed 1 meter. Generally, the lightning protection fence should be placed as close as possible to the device to be protected and installed in the box.

It is suitable for use in flame-proof and explosion-proof environments such as flammable gases, liquid storage tanks, sewage treatment plants, petrochemical plants, and distillation columns on natural gas pipelines.

2.Hexagonal stainless steel shell lightning protection grid, namely KNF48-N (P, I), etc., is specially designed for two-wire transmitters, the thread at one end of the lightning protection grid (see figure) is directly installed on the cable entrance screw hole of the transmitter, the three lead red lines of the lightning protection grid are connected with the positive signal line of the transmitter, the green wire is connected with the negative signal line of the transmitter, and the black wire is connected with the chassis and the earth, and the wiring diagram is shown on the right. The grounding wire of the lightning protection grid should be grounded with a cable with a cross-section of not less than 4mm2, and the wiring resistance should not be greater than 4.

3.Requirements for ground wire: if it is an independent ground wire, its grounding resistance is required to be no more than 4; If it is a unified ground wire of a computer information system, its grounding resistance is required to be no more than 1

4.The lightning protection barrier and the safety barrier are in a cabinet, and their installation arrangement is shown in the figure below.

The grounding wire of the household appliance can be directly connected with the water pipe or heating pipe with an insulated wire. Do not connect with ceramic tiles, which are insulators. It also cannot be connected to the wall, and the insulation resistance is too large.

Iron wire emergency is OK, commonly used can not, wire resistance is high, conductivity is not good, try to use copper wire as well.

Yes, but the conductivity of iron wire is much worse than that of copper and aluminum, so it is recommended to use aluminum wire.

Yes, but it is better to have a regular grounding wire, otherwise the contact will be poor and overheated.

Answer: Kiss, hello [heart]" The grounding wire can be replaced by aluminum wire, but the cross-section is thicker than the copper core wire. However, the aluminum grounding wire should be oxidized, and the flexibility is not as good as the copper core wire, and it is easy to break after repeated bending, so it is best not to use the aluminum core wire as the grounding wire. ”

It can be replaced with a fully grounded steel wire with good contact.

Electric gondola? I used to rent this too...

The wire rope grounding wire is really unsafe... You can't stare at them every day on the construction site, do you know what moths are coming out?

It is best to buy a three-phase five-wire cable honestly, even if they are connected randomly, at least in case something happens, we can pick ourselves out... You connect the ground wire to the wire rope, as long as something happens, complaining about you and not complaining about you, you can't run away if you lose money.

According to the requirements of the national standard, the resistance of the grounding wire should not be greater than 4 ohms, the galvanized iron wire is estimated to be not, and the galvanized flat iron is OK.

Of course. It just needs to be enough area and strength.

No, because iron does not conduct electricity.

As long as it's thick enough, it's fine.
