Take you to understand the cause of the leakage of the chassis

Some users use the computer process, accidentally touch the chassis, found that there is a feeling of electric shock, that is, the computer chassis leakage, this is how it?

Computer chassis leakage How to do, the chassis leakage reasons for many of the host, touch will have a sense of shock, this is called leakage. The cause of leakage and the quality of the chassis has a certain relationship, but the main internal accessories are problematic.

　　1. Improper disassembly of power supply

Improper installation of power will lead to leakage. There are a large number of components inside the power supply, and the space is small, disassembly is slightly improper, the component may touch the power shell. such as inductance coil, almost bare, once touched the shell, the direct result is leakage. If it is a power supply leakage, the hands of the electric shock is very strong, serious even can directly open the hand. Therefore, the installed power must be selected to ensure that the power supply itself does not leak, the installation of their own power to ensure that the insulation plastic to maintain the original position.

2. Internal cable breakage leakage

A lot of power use of the wire quality is not good, these wire once used a little longer, it may be external damage. If the damaged point is just next to the chassis, the man will feel the shock when he touches the chassis. However, the internal voltage of the computer is low, the maximum is 12V, so the shock feeling is very weak. Users can try to clean the cables centrally and avoid contact with the chassis, but it is best to replace the new power supply.

　　3. Motherboard will also leakage

The motherboard leakage, the hand feels the electric shock feeling is strong, almost and the power leakage is almost, has the obvious thorn pain. Motherboard leakage will cause all components are charged, including the motherboard on the heatsink, graphics and so on. Leakage is mainly due to capacitor damage or motherboard components to contact the chassis caused by the user can first observe all the capacitors on the motherboard is complete, and then check whether there are other cables encountered on the motherboard components. Try to minimize the system running, if the motherboard is still charged, that is the motherboard internal alignment has been distorted, need to replace the motherboard.

　　4. Computer Electrostatic release

Host Power will produce a lot of static electricity, but its internal "y capacitor" can eliminate this part of static electricity. If the power of the y capacitor damage, static electricity is nowhere to be released, leakage may occur. And this process is continuous, as long as the hands feel, there is a sense of shock. The various high-frequency circuits on the motherboard also emit radiation, resulting in static electricity in the chassis. Personal also with static electricity, touch the chassis static electricity one-time release, and then touch it.

Solve the static electricity, must use the power strip with the ground wire. Not really, you can ground the chassis. However, it is not advisable to use gas pipelines and water pipelines as grounding is not desirable, the former will be caused by the electric spark pipe explosion, while the latter appears to be reliable, but in fact, the electrical conductivity is excellent, in the case of short-circuit, its leakage current enough to make people reach a fatal degree.
