The live problem of the chassis, urgent

One reason is that the power supply is not grounded, or the live wire 0 is reversed. The single-phase socket should generally be three-phase, the left is the 0 wire, the right is the live wire, and the top is grounded. Use 50 cm steel bars to drive into the ground, and then use a leather wire to connect one end to the back of the chassis, and the first end of the wire is connected to the steel bar, and if it cannot be grounded upstairs, it can be connected to the water pipe.

Another reason is that there is a problem with the power supply of the chassis, contact the chassis shell with a pen, if the electric pen continues to glow red, it can be preliminarily concluded that the chassis power supply is leaking, and focus on checking several ground filter capacitors in the high-voltage part of the power supply.

The third reason is that there is a lot of dust in the computer case, which causes static electricity in the case.

Leakage can cause damage to the motherboard's components. Because according to the safe use of computers, it is necessary to use three-phase electricity. If you are using two-phase electricity at home and there is no grounding wire, the EMI circuit of the computer power supply (its function is to filter out the cluttered part of the grid voltage and ensure the stability of the output voltage, this function is only available for the power supply that has passed the national electrical power safety certification) will make the metal part of the chassis with a voltage of 110V, which has far exceeded the safe voltage of 36V, which is a very dangerous thing.

Therefore, in order for you to use the computer safely, you must connect the ground wire, and ensure that the ground wire is well grounded, at the same time, you should pay attention to the quality of the power strip and power cord, and do not use products with poor quality.

That's the case now! Ask the service staff at the time! I said it's not a leak in the case! Say my total power supply is not grounded! It's static electricity! It is said that the voltage is relatively high, but the current is small! Electricity doesn't die! But as soon as I touch the back of the case, my hand hurts!

I couldn't help it, I led a grounding wire to the installation screw of the case power supply! Looks better now!

If you want to ground a wire, be sure to find a good grounding! Such as a water pipe or something! The main thing is that the contact with the ground should be deep and large!

According to the person who served the after-sales service, it was not leakage! Yes, if you want to think about it, the leakage protection switch I installed will jump! Do you have a leakage protection switch?

Is there a jump? If you are still afraid of problems, find a small current leakage protection switch to install at the upper end of your tow board, if it jumps, it will definitely be power leakage! If it doesn't jump, it's because the power supply doesn't have a ground terminal, resulting in static electricity!

It seems that only a ground wire can solve the problem relatively quickly!!

Kindness. It's a leakage fault. But I wonder if the socket is connected to the bottom line? This is generally not the case. There is a good chance that the socket does not have a ground wire. Look at it.

My camera sometimes has electricity.

I don't know if you're talking about static electricity, if it's static electricity, it doesn't matter much, now the chassis on the market are very rubbish, and it's normal to have static electricity.

Grounding wire: You just have to connect the hole in the triangle plug with a wire and bury it in the wall.

110v isn't that exaggerated. If it really is, you have to take a closer look at whether it is the motherboard, ** short circuit directly touched the chassis.

Desktops, with static electricity is normal. Because the general power plug is not grounded.

Normal static electricity, no effect on the computer.

110v Then hurry up and take a look, it's a **short circuit. o(∩_o~

The old house has radiators, and connecting the chassis to the heating is equivalent to grounding.

I'm a god

Your machine is blistered, right? Let's take it out and dry it first, everywhere is electrified, I'm dizzy.

Don't look for faults, it must be a problem with the power supply, and it is impossible to leak anywhere in the computer to 110V

Just kidding, it's going to be a hitter right away, the child touches it and cries the electricity, check the power supply of each line, maybe the ribs are broken, a short circuit occurred, turn on the lines that are put together, and then look at it, if the line is not wrong, the old power supply is inside, don't think about other places, only the power supply, go to a friend to disassemble and replace it, and then move your computer to a friend's house to try, it really doesn't work to repair the flower, 110V is very dangerous for children.

Take a look at what the post bar says about your power supply, the reference below.

1.Causes of computer chassis electrification: Computer chassis is electrified, which is a very common phenomenon.

Because the computer power supply of Hewu is a new type of switching power supply, it cancels the traditional transformer step-down, and adjusts the output voltage by changing the on-on and off-time of the switch, which is a new, high-efficiency, low-volume, light-weight power supply. However, since there is no conventional power transformer to separate the mains power from the load, the internal input part of the power supply is "thermoelectric". The output part is isolated by a switching transformer, so it is "cold ground", but because the power supply is in the working state of high voltage, high flat frequency and high power, it will inevitably produce strong static electricity, and the electric tester is used to test the liveness.

However, because the current carried in the chassis is very small, it is generally not dangerous.

2.Solutions for live computer cases: The following are used flexibly.

1. First of all, see whether the three-wire socket and the three-wire plug are connected correctly, and whether the common ground wire, the live wire (i.e. phase wire) of the power supply, and the neutral wire of the electrical return source are correctly connected. (The power supply usually has an imaginary ground terminal, and the voltage at this point is considered to be zero, and most power supplies are negative as the reference ground, so the switch is connected to the positive end of the power supply.)

If the positive terminal of the power supply is set to ground, the switch may be connected to the negative terminal of the power supply. Household electricity 220V AC bar, this is not divided into positive and negative poles, only zero, live wire, generally connected to the live wire. )

2.Open your own case lid. Look at it should be so dirty.

Use a brush (gently sweeping) or a pump (one person to pump, one person to blow) to remove the dust from the computer. (Be careful not to damage the components of the motherboard with too much force) The most important thing is to clear the power box and the vicinity. (You can use a pump and a brush together).

3.If the above method. Still not working, it's a problem with your motherboard and power supply. In your case, it's 220V. It's mostly a problem with your power supply. If you are a DIY expert, you can add a few insulating pads to the motherboard.

It can't be solved anymore. You're going to have to dismantle the power supply. Take the power supply apart and clean it up. It can't be solved anymore. It's going to cost money......Find a new power box and try it.

4. Some users use ordinary lighting electricity at home, only live wire and neutral wire, and no grounding wire, then the three-head socket does not work, it is recommended to use metal wires, the chassis metal outsiders are connected to the earth, some people connect the chassis with water pipes, etc., it is not recommended to use this method, if the power leakage phenomenon really occurs, it is more dangerous.

5. Find a wire, connect one end to your chassis, and the other end to a metal pipe, and bury it in the ground (the safest).

What my friend said earlier is both right and incorrect.

It is normal for the host to be electrified, because the host shell and the circuit motherboard ground wire are connected by a wire, which is designed to improve the safety of electrical appliances.

The metal shell of any electrical appliance will be electrified, and the size of the charge depends on the voltage of the appliance, and small electrical appliances will not react at all if they use direct current below 36V.

Like color TV and computer use of alternating current belongs to high voltage, it will naturally be electrified, people who are allergic to electricity feel very numb, people who are not allergic to electricity do not feel anything, but do not turn on electrical appliances when it rains and thunders, lightning causes the voltage of electrical appliances to rise sharply, and even hurt people. The live voltage can be tested with an electric pen, the light is on to indicate that it is too high to hurt people, and the light is not on means that it is too low to hurt people.

The solution is to find an insulated wire that is fixed at one end to the computer case and the other end is connected to the ground (preferably underground).

The best way is to use three-wire power supply, so that point A has a good grounding, and the shell and chassis of the power supply will not be "electrified". (This method is recommended).

For users who cannot use the three-wire power supply for various reasons, users can make a ground wire, insert a one-foot-long iron wire into the relatively wet ground, and use the wire to connect the iron wire with the metal steel plate of the computer case.

If the previous two methods can not do the user, do not need to pay attention to this leakage current, because it will not cause danger to the human body, some users use a wire to connect the computer chassis with the water pipe at home, although this method can solve the problem of leakage current, but it is more unsafe, because the grounding effect of the water pipe is unstable, in case the computer really leaks, it will be very dangerous, this practice is not recommended.

Because a certain cable in the chassis is tied to the chassis, this problem is very troublesome, and it is necessary to disassemble all the things in the chassis and reinstall it to troubleshoot. Or it's a case power cord quality issue. I've tried removing the original power cord from the case and attaching the power cord to the monitor.

The test was electrical, and the light did not turn on.

The reasons for the electrification of the desktop computer chassis are as follows: (1) Due to the large filter capacitor of the host power supply, in the process of charging and discharging, when the power is shut down, it forms a loop with the ground wire through the isolation balance resistor to release the storage charge of the large capacitor, and the ground wire is directly adjacent to the power supply shell, and the shell is connected with the chassis of the host.

Normally, the case is not electrified, and the reason for the live is that the power supply line in your home does not have a good grounding wire.

The power cord of the main unit is a three-pin plug, which should be plugged into a three-pin socket. Your socket may not have a well-connected ground wire. A good grounding wire is very important!

In addition, the three holes of the socket, the wiring position of the ground wire, the neutral wire, and the phase wire can not be mistaken, E ground wire, N neutral wire, L live wire, do not connect the reverse. It can also be charged if it is wrong.

Also, there may be a quality issue with your power supply, check it out.

The first solution is to connect a good ground wire to ensure safety! Radiators, alloy windows, and gas pipes do not replace the ground wire, and if a live chassis is connected to it, it may make them electrified too! You can bury a piece of metal in the ground, connect it to the e-pin of the power outlet with a wire, and do not connect it directly to the chassis to avoid inconvenience.

The Jinhetian chassis is okay, but it's a lot worse than Cooler Master, SilverPlus, Weixun, and TT. TT v3 around 300, and the Great Shadow Winger is better.

This is also the case with the power supply of the Great Wall, which is first-class in China, and the performance and ** are not advantageous compared with the Taiwan system. Therefore, we recommend Antek's BP430, with a rated power of 430W, and Delta OEM 80PLUS white label, the actual efficiency is higher than that of the bronze medal, ** only 299.

Don't buy a case with a power supply, because the power supply with it is very bad. Be sure to buy them separately.

Any one of the chassis will do. The power supply should be rated at more than 300W. As long as you don't buy miscellaneous cards, you're fine. Recommend Antec's VP450 (rated 400W) $299....This is the most popular power supply recently.

All computers actually have this problem, but many people don't notice it.

If you wear a pair of dry shoes to touch the case, you won't feel it, which is why many people don't notice.

It is a kind of induction electricity measured by the voltage tester, which is leaked out of the computer's switching power supply, not only the main machine will be like this, but the CRT monitor will also be like this, but also because the noisy ruler is not noticed by you.

This has nothing to do with zero fire connection, and the switching power supply is basically indistinguishable from positive and negative.

The electricity leaked from the switching power supply is safe and basically will not cause any harm to people (in fact, it should be grounded, but it is generally not treated at home).

If you always feel that this is not good, then you can find a wire, connect it to the main chassis, and connect the other end of the wire to the ground treatment, or connect it to the anti-theft net of your home, or connect it to the civil electricity.

Ground (is the ground wire.)

Not the zero line, remember)
