机房接地规范(Machine room grounding code)
The grounding system is an important part of the environment of the computer room. attribute.
Electrostatic grounding: mobile devices or mobile objects in the pipeline, generating static electricity due to friction, it gathered in the pipe to the container, and storage or processing equipment, forming a high potential for personal safety and equipment and buildings are dangerous.
Electrostatic grounding is made. Once static electricity is produced, it is introduced into the ground to eliminate the possibility of aggregation.
DC grounding (also known as logical grounding, signal grounding) : computer and all micro electric equipment, the CMOS integrated circuit in DC voltage is lower, in order to make the circuit work computer, microelectronic devices of the same system with the same reference point "potential”, all the equipment zero potential point connected to a grounding device, it can stabilize the potential of the circuit, to prevent outside interference, it is called the DC grounding.
Lightning protection and grounding for lightning surge current: leak into the earth, so that the object to be protected from lightning or lightning hazards such as surge voltage and over current, all buildings, electrical equipment, network lines, uncharged metal parts, metal sheath, lightning arrester and all water and gas pipes shall be connected wi
