There is static electricity on the computer case, how to eliminate it? My room doesn t ground proper

This is all available, especially when it is dry, it is recommended that the room maintain a certain humidity.

It can only be recommended that you install an ionizing fan, which is very effective in eliminating static electricity! And it's cheap, just over 300.

The cause of static electricity: It is caused by the non-standard wiring of your power outlet.

Static electricity in computer cases is not only uncomfortable for the human body, but more importantly, unsafe for computer hardware. According to the requirements of the specification, the computer wiring power socket should use a single-phase socket with a safety grounding wire, that is, the socket with three holes that you usually see, the top hole of the socket is connected to the safety grounding wire (if there is no safety grounding wire, you can lead a wire to the ground), the lower two holes, the hole on the left is connected to the power zero line, and the hole on the right is connected to the power live wire. In this way, there will be no static electricity in parts such as the computer case, which is also good for protecting the computer hardware.

The chassis is wired to the metal pipe that supplies the radiator water.

With a pen, ** there are sales

The reason why the chassis is quiet:

1) There are detailed instructions in the computer's manual, "In order to ensure the normal use of your computer, please ensure that the computer is well grounded." "The root cause of a computer enclosure being electrified is because there is no ground wire installed in the home or there is poor grounding.

2), because the current market sales of computers are CCC certification, the CCC certified power supply must use EMI filter circuit, because the filter circuit has capacitance and live wire and ground wire communication, if there is no installation of ground wire at home, more or less on the surface of the case will appear "live" phenomenon, which is a normal phenomenon.

Solution: The way to release static electricity is to unplug all the external wiring on the main chassis (notebook, you need to remove the battery), and then empty press the host switch about 5 times, it will consume the static electricity inside, and then turn on the machine is normal.

Connect the host to a real ground cable. Use a regular plug-in board with grounding, the premise is to ensure that the indoor wall electricity has a real ground wire. On the computer case, connect a ground wire with insulating skin to the heating pipe or metal water pipe, generally the current heating pipe has equipotential, even if there is no equipotential can effectively remove static electricity.

1.The most important and decisive factor is also the decisive factor. Problems with the power supply itself.

The power supply you plugged in itself has strong static electricity, and there is no ground wire, so it causes serious static electricity on your computer. If you don't believe it, switch to a different place to connect to the computer to ensure that there is no static electricity. Static electricity is not just about electricity, it will burn out the hardware.

I burned two 9600 graphics cards just like that.

2.The air is humid, and this is a supporting factor.

3.It may be that there is a slight short circuit in the chassis that is causing leakage.

Solution. 1.Replace your power supply. Plug in the computer from another location. It's a good idea to change the computer at the same time. The problem is usually absolutely solved.

2.Connecting to the ground wire, connected to the concrete floor, is definitely a good way, for the sake of hardware. You don't want to burn out your graphics card too.

Electricity may be caused by humid air, or it may be caused by power supply. Static electricity can damage computers. Usually you can put down static electricity for a while.

The specific method of discharging static electricity: unplug the power cord behind the case, and then press the computer start switch, which can release static electricity. Press a few more times.

Tie a wire to the screw at the back of the case, and then ground the other end, so that the electricity can be channeled to the ground.

Generally, it is caused by excessive dust accumulation in the chassis without a grounding wire on the power plug.

Method 1Use a hair dryer to remove dust, mainly inside the power supply. General problems can be solved2

In the place where there is electrostatic inductance, connect a wire (can transmit electricity) to connect the ground wire or heating pipe, the purpose is to guide the static electricity, as long as it is close to the computer and has the ground can guide the current of the object.

3.The cost-effective way is to directly replace the source of the problem, generally no grounding wire may be the power socket is not grounded, so only by replacing the chassis power supply, the general problem can be solved.

Do not plug in the power socket of the host, plug in the three holes on the wall, and there is a grounding wire inside.

1. Static electricity will not only bring people pain in flesh and skin, but the most important thing is that it will break through the chips on the board and memory, which will inadvertently cause a lot of losses, so it is necessary to prevent static electricity for the chassis.

2. Static electricity is sometimes brought to the chassis by the user himself before contacting the chassis, and it is a high-risk area for generating electric charge in a high-temperature and dry room, due to the low air humidity, chemical fiber clothes, carpets, cushions, etc. are rubbed, which will produce static electricity. When static electricity accumulates to a certain voltage, it is released, which is the phenomenon of "electric shock". When the user's hand is in direct contact with the board card and memory chip in the case, static electricity will instantly enter the internal circuit from a pin of the chip, burning the transistors and metal wires in it, causing invisible damage.

3. Therefore, before opening the chassis, you need to first release the static electricity on your hands, such as touching metal objects such as door handles and water pipes, or touching the wall or wet towel with your hands to "release" the static electricity in your body. The best thing to do is to wash your hands so that static electricity runs away with the water, and then dry your hands before opening the case.

4. Inside the chassis, the power supply will also produce a large amount of static electricity, especially the capacitors of some inferior power supplies are cut corners, and the static electricity will be released nowhere to release, and it will run into the chassis outside the power supply, so the chassis must be grounded. In this case, a power strip with a ground cable is required. At the time of installation, many users are accustomed to asking the merchant for a power strip gift, and the merchant will naturally not give any high-quality products, so many cheap and inferior power strips are used at the power inlet end of the computer.

If the ground wire is omitted in these inferior strips, then static electricity cannot be released through the ground wire.

5. Then you can build this grounding wire for the chassis by yourself, first find a wire. Peel off both ends to expose the copper wire, and tighten the screws by wrapping one end around the metal screws of the case. Tie the other end to the water pipe, heating pipe or aluminum window (make sure they are connected to the ground) to prevent static electricity.

It should be noted that do not tie the grounding wire to the gas pipe, as the electric spark of static electricity will cause the gas**, which will be very dangerous.

6. Create a real grounding strip.

Even if you change the power strip with a ground wire, it may not be able to prevent static electricity. Whether you live in a building or a bungalow, the electrical wiring in your home has already been formed, and if the power socket on the wall has only two phases and is not grounded, then all the electronic products plugged into the socket will not have a grounding effect. As a result, it is possible to create a "real" ground strip with the help of the previous method.

The power plug of the chassis is generally three-phase, one phase live wire, one phase neutral wire, and the one phase at the top of the middle is the ground wire. The same is true for the sockets on the strip plugs, and the ground jacks of all sockets are connected in parallel. Remove the end of the ground wire in front that was originally tied to the chassis screws, tie a small piece of metal, and insert it into any ground wire jack in the power strip, so that all the sockets on the socket are grounded, and then the power supply of the chassis is also grounded.

In general, the plugs of these devices are three-way plugs, and one of the plugs is a grounding wire, which can channel static electricity into the ground. The most likely thing in your case is that your drag strip uses two plugs or the grounding wires of the three sockets on the wall are not grounded, and the best solution is to replace the drag strip with three plugs to ground the machine; The easiest way is to find a few wires to connect one end to the surface of the case or speaker, and then drag the other end to the ground, which can solve the problem of static electricity.

If it is a building, the top jack of your three-prong power socket is the ground wire, from the power socket to the computer (PC) are used with three wires, if it is a bungalow, nail an iron rod or iron pipe of more than one meter outside the window and then connect the wire to the computer (PC) case, or connect to the iron water pipe, but from the place where you are wired to the pipe before the pipe into the ground can not have a plastic pipe.

It is estimated that there is a problem with your computer's power supply, and it is recommended that you check whether the power supply is leaking, and in a situation like yours, it must not be a simple static electricity, it should be a leakage phenomenon.

Generally, it is 220V in series, and after the EMI filter inside the power supply, the chassis has about 110V electricity, and the current is a few milliamperes.

1。The computer chassis cable is generally a three-core wire, a three-core plug, and the middle is the 2 of the ground wire. If it's inconvenient, buy a transformer with 220V isolation, and you'll be fine3. If it's inconvenient, try to swap the neutral line and the live wire position.

1. Ground the chassis.

Although the power plugs are all three-phase, if the main unit is grounded with a wire, it is more conducive to eliminating electrostatic interference.

2. Wipe the chassis with a damp rag.

It also helps to eliminate static interference.

Check whether there is a leakage short circuit in the connection. If you don't have one, find a thin wire to connect to the ground.

The degree of static electricity in the computer case makes the leakage switch in the home can also play a protective role and will be safe.

If there is no leakage switch, it is necessary to install the leakage switch to ensure safe electricity use.

It is recommended to replace the three-core plug socket, wiring board, and wall socket in time to replace the three-core plug socket in time and complete the safety grounding. Safety is more important, and you can't ignore it for the sake of saving trouble.

If the static electricity in the computer case is serious, you can replace it with a new computer power supply, and the leakage is caused by the computer power supply.

The chassis is connected to the wire screws and connected to the molten iron pipe, if not, hit 1 nail and connect it to the wall.

Upstairs, they all said that there is no ground wire at home, what is the use of putting the plug bar?

It is recommended to connect it to the water pipe, or to the heating pipe, or to the geothermal water separator, if it is a bungalow, just outside the corner of the wall, nail a steel bar into the ground, and connect it to the chassis shell with a wire.

I had a brick floor, so I solved the problem right in the house, and I remember to weld a 6 bolt to it before I nailed it in to make it easier to connect the wires.

You have to modify it in the socket row! Put the grounding wire on the top of the triple plug and you're OK!

Chassis static electricity: Connect the other end of the wire to the metal water pipe to eliminate static electricity.

Since the root cause of live electricity is that there is no easiest way to install a ground wire, the easiest way is to connect a wire directly from the chassis and connect the other end of the wire to the metal water pipe. When connecting, you need to scrape off the anti-rust layer on the water pipe, and tighten it several times.

As long as we connect the ground wire, the chassis of the host will not turn red when we test it with a voltage tester. However, this connection method is a temporary emergency use, and the home must ask a professional electrician to install the ground wire correctly to prevent the water pipe from being energized due to the "formal leakage" of other household appliances, and the injury accident occurs.

Chassis Static Precautions:

For the safety of computer equipment, for schools or other qualified units, when using computers collectively, anti-static floors must be set up in the computer classroom, and ordinary chemical fiber carpets must not be used.

The ground wire of the power supply used by computer equipment must be well grounded.

It is recommended to use a three-pin power socket, and of course, the power cord must also be three-pin. Some people use a wire to connect the surface of the chassis to the ground or water pipes, but this method does not achieve good results. <>

The power plug board is a little better, and it really has a ground wire.

There is also a soil method, connect a metal wire to a random place behind the chassis, connect the chassis at one end, and put a water cup at the other end, put some salt water in it, soak it in the water, and then electrolyze.
