Question:

Do you have a grounding grid for your own anti-static floor?

Do you have a grounding grid for your own anti-static floor?

Answer:

As long as the grounding network can do a good job without another grounding
The use of the floor of the machine floor of the ground floor of the use of the floor below the trace of grams of Yao Yao long-chiun super-magic copper plate on the line, the room lightning protection grounding, anti-static grounding, equipment, metal shell grounding and so on the use of the bus, the formation of the engine room Local equipotential, and then the bus with the machine room of the local equipotential bonding terminal can be connected.
According to the national elevator inspection regulations and GB7588-2003 requirements, the elevator power supply system requirements are TN-C or TN-CS system, and your own grounding network, is generally connected with the earth directly, the ground wire is not in the total air (TN-CS) or directly connected to the power supply neutral point of the transformer (that is, the TT system is not in compliance with the relevant regulations.
The so-called anti-static floor is actually the conductive floor, people walking on the floor above, the friction generated electrons, the ground is conductive, the electrons through the floor into the bottom of the floor of the conductive glue and copper foil, copper into the underground conductor into the earth , So that the surface of the floor there is no charged electrons, there will be no adsorption of dust in the air. If not grounded, the electronic can not enter the earth, the floor will not play the role of conduction. Antistatic flooring, also known as a dissipated electrostatic floor, is a floor that, when grounded or connected to any lower potential, allows the charge to dissipate, with a resistance of 10 in the order of 10 to 10 Between the characteristics. "GB-2008 electronic information system room design specifications" provides: anti-static floor or floor surface resistance or volume resistance should be 2.5 × l04 ~ 1.0 × 109Ω.
