In order to reduce the influence of static electricity on computer equipment, in addition to anti-static floors and partitions, grounding shielding is generally adopted. The grounding of the equipment shell is the most basic anti-static measure, which requires the computer itself to have a reasonable grounding and shielding system, so that when the electrostatic charged body contacts the computer shell to discharge, static electricity can leak into the ground through the grounding wire without causing system operation failure. Usually, the instantaneous electrostatic potential is too high, which is easy to cause ground potential fluctuation. Secondly, it is necessary to cut off the intrusion of electrostatic noise into audio channels as much as possible, and try to use shielded wires when jumping audio and digital wires. The outer insulation of the shielded wire should be well grounded, so as to leak the charges accumulated around it.
In view of the fact that grounding system is an important means to improve the reliability of computer network, suppress noise and ensure the safety of computer room equipment, the grounding of computer equipment should be taken seriously. If we don't pay enough attention to it or the grounding system is not handled properly, it will affect the stable work of the computer and even cause failures, and even burn the interfaces and equipment, which will seriously endanger personal safety.
The requirements of computer application technology for "ground wire" are getting higher and higher, which requires us to constantly explore and sum up experience in our work.
