What is the cause of chassis leakage?

Chassis leakage refers to the leakage of current from the computer chassis during normal use. This may cause current to be conducted to the ground or other parts through the metal shell of the chassis, posing safety risks to users. Case leakage may cause equipment damage, short circuit, or even electric shock.

There are many possible reasons for chassis leakage. The following are some common reasons:

1. Power supply failure: The power supply of the chassis is an important part of the computer system. If the power supply itself fails , such as power overload, short circuit, etc., may cause chassis leakage. In addition, poor wiring of the power supply may also cause leakage problems.

2. Wire aging and wear: As the use time increases, the wires in the chassis may become aging, and the protective ability of the insulation layer decreases, resulting in leakage. Especially for computers used in high-temperature environments, the risk of wire aging is higher.

3. Ground wire connection problem: The metal shell of the chassis is usually connected to the ground through a ground wire to ensure the safe conduction of current. If the ground wire is poorly connected or disconnected, the chassis may have leakage problems.

4. Non-original power supply: In order to pursue low prices, some users may purchase some power supplies that are of poor quality or have no certification. Various quality problems may occur with these power supplies during use, including leakage.

5. Static electricity problem: Static electricity is one of the common problems in electronic equipment. If the metal shell of the chassis does not have effective electrostatic protection measures, static electricity may cause the chassis to leak.

In order to avoid the problem of chassis leakage, we can take the following measures:

1. Purchase a reliable power supply: Choose a reliable brand and certified power supply to ensure that the power supply can work properly and provide stable current. output to reduce the risk of chassis leakage.

2. Check the status of the wires: Regularly check the wires inside the chassis, especially the aging or severely worn wires, replace them in time to ensure the integrity of the insulation layer.

3. Strengthen the ground wire connection: Make sure the ground wire of the chassis is well connected, using a solid connector and a suitable ground wire.

4. Anti-static protection: Use carpets, cushions and other tools with electrostatic protection measures to avoid static electricity accumulation and discharge, and reduce the possibility of chassis leakage.

In general, chassis leakage is a serious problem that requires us to have a certain understanding and maintenance of computer hardware. By choosing a reliable power supply, regularly checking wires, strengthening ground wire connections, and anti-static protection, we can effectively reduce the risk of chassis leakage and ensure the safe operation of the computer.
