All electrical equipment sharing the same ground wire is not acceptable

All electrical equipment can share a grounding device, just like a large basement with the entire commercial and residential community, the basic grounding device of this basement is not only for all low-voltage electrical equipment, substation and distribution room.

of grounding and repeated grounding.

It is also connected to the lightning protection and grounding of the building. Called joint grounding or shared grounding, this form of grounding, grounding resistance.

The value must be no more than 1 ohm.

From this grounding device, many grounding trunks can be drawn for protective grounding and equipotential bonding everywhere.

or repeat grounding.

What you said about sharing a ground wire should be a small range of grounding, otherwise it is impossible to rely on a single grounding trunk line to complete a large range of grounding as mentioned above. So it's okay for all the electrical devices you said to share a ground wire (like a ground wire with a grounding wire.

The key is that this ground wire should be able to meet the function of the grounding trunk line, (that is, the grounding resistance value and the grounding wire cross-section). Of course, it is better to sub-system grounding.

In addition, the specification requires that the grounding requirements of each electrical appliance are directly connected to the grounding trunk and shall not be connected in series. Let's say: you have a few motors, a few devices, a few sockets.

The grounding wire of the motor of different power cords should be directly drawn out from the grounding bar, and the grounding wire of the motor (or equipment, socket) of the same power line is directly led out from the grounding bar, and the grounding wire from the first motor (equipment, socket) to the next motor (equipment, socket) needs to be connected with the "head", that is, when the first grounding is grounded, the three grounding soft wires are put together and tinned, and then connected to the first one (only), and the other grounding wire is connected to the latter one (only), and so on. If the grounding wire is connected at the first place, and then the grounding wire is drawn from the grounding pile of this equipment to the back, it is a series connection, which is absolutely not allowed. Because if the front grounding pile is in poor contact or loose, the back is equal to no grounding.

In the case of steel grounding wires (galvanized flat bars, round bars.

On the direct welding connection (the lap length of the flat steel is more than twice the width of the flat steel, trilateral prism welding; The lap length of the round bar is more than 6 times the diameter, and it is welded on both sides).

Electrical equipment can be powered by a power supply and can share a common ground, not the same power supply is connected to the ground separately.

Without voltage level, the power supply cannot be co-grounded.

Ground wires can be shared.

Strictly no.

Can the grounding wires of several devices be connected to a single grounding point? If not, why?

This problem is divided into two situations: 1. Several devices are connected in series to the same grounding network. 2. Each device is separately grounded to the same grounding stool network.

In both cases, it is possible to share a single ground grid. In the first case, if all the equipment is connected in series and then grounded, the grounding of the equipment needs to be reliably grounded, and one of the devices is unreliable, and the shell of the other equipment will be electrified. It is better not to connect in series to ground.

I hope it helps, give a thumbs up if it helps, thank you.

Can the grounding wires of several devices be connected to a single grounding point? If not, why?

Can the grounding wires of several devices be connected to a single grounding point? If not, why? Hello dear, multiple devices can share a ground wire.

Note that the common grounding point, the indirect location of the electrical appliance must not be connected in series, if the use of series, the current end of the grounding electrode is disconnected, the back of the file teasing Chang electrical appliances will not have grounding protection, there will be a safety accident of electric shock. The correct connection method is that all electrical appliances can be connected in parallel. Because we use electrical appliances in the process, in order to ensure the safety of electrical appliances, especially when some shells are made of metal, in order to prevent leakage from causing harm to people, we have specially assumed the wire protection function, these boundaries will leakage, and the current will be directly conducted to the earth, and each family uses a ground wire, that is to say, all the luck can be used together to refer to the ground wire to ensure the safety of electricity.

Summary. Dear, no, a grounding wire connected to multiple electrical units is called a serial connection to the ground. After the grounding wire can be grounded at multiple points, the grounding of each equipment is connected separately from the grounding wire.

Dear, no, a grounding wire connected to multiple electrical lead Huisong is called a string of rotten connection to Huai Zheng. After the grounding wire can be grounded at multiple points, the grounding of each equipment is connected separately from the grounding wire.

What is multi-point grounding.

It is that several electrical appliances are connected to the ground wire.

However, they are all separately connected from the grounding wire.

Oh, you know, the ground wire is usually connected to the machine somewhere.

Is it that the greater the power, the greater the static electricity.

The ground wire is attached to a special binding post grip or to a metal casing for electrical equipment. Generally speaking, the ground wire is the wire connected to the earth, which can introduce leakage current into the ground to avoid the occurrence of contact accidents, so it is also called a safety loop.

It is the greater the power, the greater the static electricity.

Grounding wire, whatever wire you want, copper wire and aluminum wire are fine.

Dear, the regulations do not clearly stipulate what material must be used for the grounding wire, and we mainly consider what material to choose from the cost performance of the project.

Okay, thank you.

Hello, I also want to ask if there will be leakage after the ground wire is connected.

Pro, the grounding wire is to prevent leakage from hurting people and provide safety guarantees. You have connected the ground wire, and there is leakage in the skin, which means that there is a problem with the line connection and needs to be checked, and the cause of the leakage is found in the Tuanqi key.

Summary. No. Multiple devices cannot share a single ground wire. Because of this, if the common ground wire is disconnected, the leakage of one of the device shells will cause the other device shells to be electrified, which is dangerous. It also does not symbolize the relevant provisions.

Those who don't celebrate can do it. Multiple devices cannot share a ground wire. Because of this, if the common ground wire is disconnected, the leakage of one of the equipment shells will cause the other equipment shells to be electrified, which is very dangerous. It also does not symbolize the relevant provisions.

How many ground wires do you need to use for those devices?

Try not to reconnect if possible.

If there is no condition for Tomono: but a reminder. Share a grounding point, electrical indirect location must not use the series connection method, if the use of series, the current end of the grounding electrode disconnection in the case of shouting, the back of the electrical appliances will not have grounding protection, there will be a safety accident of electric shock.

The correct connection method is to use the parallel connection method for all electrical appliances.

Oh, what you mean is that the grounding wire can not come out of one of the wires, but it is allowed to come out of the subway.

Right, right. That's what it means.

The machine grounding wire is generally connected to the equipment somewhere.

Then there is the logo of the ground wire, if there is no can be connected to the shell screw.

The power of 3 kilowatts requires how many meters of grounding.

Is it that the greater the power, the greater the static electricity.

50 cm. 1.The effects of materials and impurities.

In general, impurities have a tendency to increase static electricity; However, if the impurities can reduce the resistivity of the original material, the addition of impurities is conducive to the leakage of static electricity. When a liquid contains water, additional static electricity is generated during liquid flow, agitation, or jetting. Static electricity is also generated during the settling of water droplets in the liquid.

If water accumulates at the bottom of the tubing or oil tank, it is easy to cause static electricity accidents after agitation. 2 Influence of process equipment and process parameters The larger the contact area, the more positive and negative charges of the electric double layer, and the more static electricity is generated. The rougher the inner wall of the pipe, the larger the contact area, the more opportunities for impact and separation, and the greater the flow current.

For powders, the smaller the particles, the larger the surface area of a certain amount of powder, and the more static electricity is generated. The greater the contact pressure or the stronger the friction, the more charge separation will be increased, resulting in more static electricity. 3 .

Influence of environmental conditions and time of air humidity. In many cases, conductive ground orange surface can enhance the leakage of static electricity and reduce the accumulation of static electricity. Surrounding conductor arrangement.

For example, the voltage is not high when the transmission belt just leaves the pulley, but when it is turned to the middle position of the two pulleys, the capacitance is greatly reduced and the voltage is greatly increased due to the increased distance.

16 square copper wire can be used as a grounding wire.

Can a machine connect two ground wires, and is it useful to put the wire in salt water as it is said on the Internet?

You don't need one.

No, it doesn't. The earth needs to be introduced.

In principle, the electrostatic grounding wire and the equipment grounding wire should be separated, mainly for the safety and hazard issues on the electrostatic wire. Although the requirements on the electrostatic wire are not particularly high, and the equipment on the grounding line can not be connected to the equipment, the grounding is to prevent the equipment from leaking and hurting people. But in order to prevent electrostatic hazards, you must find a suitable place to make an electrostatic grounding pile.

It cannot be shared, and the equipment uses alternating current (high current, low voltage) and static electricity (high voltage, low current).

Although both wires are used for grounding, it is the wrong thing to do if they are connected together. The correct thing to do is to ground the two separately and not share them. If they are shared, when the ground wire fails, the equipment connected to one end of the ground wire will carry a certain voltage, and the equipment will not necessarily be damaged, but it may cause electric shock to the human body.

Theoretically, both electrostatic wires and ground wires have zero potential and are both functions that protect the equipment. But the two are not shared. This is because these two types of wires are different from the objects that make up the working loop with the earth in the working process. Yuna.

The electrostatic hole is a working circuit formed between man and the earth, which mainly has a protective effect on the product; The ground wire is a working circuit formed by equipment and the earth, which can protect people in addition to protecting equipment.

OK. The grounding part of the power distribution system.

1) Phase line (L). The conductor that carries electrical energy is not grounded under normal circumstances.

2) Neutral (n). A conductor that is connected to a neutral point in the system and can act as a conductor for transporting electrical energy.

3) Protect the neutral line (PEN). A conductor that acts as both a protective wire and a neutral wire.

4) Power grounding point. Ground the point where the power supply can be grounded, usually a neutral point.

A plurality of electrical appliances can share a grounding wire, the role of the ground wire is to reliably connect the shell of the equipment or electrical appliances to the line of the earth, the purpose is to prevent electrical leakage, the chassis is electrified, all the grounding is eventually connected to the underground, for safety, we must ensure that the ground wire is well grounded in order to work.

In order to achieve the purpose of connecting with the ground, the grounding body is a conductor or a group of conductors that are in close contact with the soil sheet (earth) and provide an electrical connection with the soil (earth). A grounding wire is a wire that forms the ground that connects a device, device, wiring system, or neutral wire to a grounding body.

A grounding grid consists of a group of interconnected bare conductors buried in the ground to provide a common ground for electrical and electronic equipment and metal structures. A grounding device is used to form a connection to the ground. It consists of a grounding wire, a grounding body, and the earth (soil) surrounding the grounding body.

In fact, all the ground is one, the earth, our earth, how do you connect, in fact, it is one, I don't know if you understand, that is to say, you can connect it like this, it is used in many ground wires, in fact, it is still one, but it is recommended that your ground wire is not too thin, and it must be reliably grounded, it is best to plug it into the wet soil!

It's parallel, yes, within the rated voltage.

It seems that there is only one home grounding wire, and you can't connect it if you want to connect more.
