How to install the anti-static grounding device
For good grounding, several larger copper plates should be buried in the large pit outside, and then use copper bars or copper meshes to connect indoors to achieve good results (other metals are also OK but are susceptible to corrosion)
The grounding system of the computer room is an important means to prevent the interference of parasitic capacitive coupling, protect the safety of equipment and people, and ensure the stable and reliable operation of the computer system.
The grounding system of the electronic computer is *simple and *economical in anti-interference design, and it is also a way of *significant effect. If the grounding can be combined with the shielding correctly, the noise problem can be better solved.
Therefore, in order to ensure the safe, reliable, and stable operation of the computer system, and to ensure the safety of equipment and people, appropriate grounding systems should be designed for the different requirements of different types of computers.
According to the requirements of the computer grounding system in the national standard "Computer Technical Requirements", computing stations generally have the following types of grounds:
The DC ground of the computer system; the resistance value is not more than 1Ω.
AC working ground; the resistance value is not more than 4Ω.
Safety protection ground; resistance value is not more than 4Ω.
Anti-static grounding; resistance value is not more than 4Ω.
Lightning protection ground; the resistance value is not more than 10Ω.
The so-called grounding refers to connecting a certain point in the circuit or a certain metal shell with the ground with a wire. The goal is to facilitate the flow of ground current. Therefore, the lower the ground resistance, the easier the ground current flows. In addition, for the grounding of electronic computer systems, it is also desirable to minimize potential fluctuations that cause noise. So the ground resistance is also as low as possible.
