Why lightning grounding? For the lightning protection of the instrument, we can use the lightning protection module, the lightning protection module is grounded to provide a discharge channel, and the lightning discharge current can be quickly conducted and discharged when the lightning strikes. The lightning protection module has the effect of lightning protection only after being grounded. Cable pipes, metal trays, armor layers, shielding layers, etc. have a good shielding effect after grounding, which can greatly reduce the current and voltage generated by lightning induction of cable wires, so as to protect instrumentation equipment from lightning damage. How to lightning protection and grounding of instrumentation? When the signal line of the instrumentation control system enters the indoor from the outside, the lightning protection grounding connection should be carried out when the power protector or other occasions that need to be set up to set up the lightning protection grounding connection. The lightning protection grounding of the control system of the instrument should be shared with the lightning protection and grounding system of the electrical system. However, grounding equipment should not be shared with stand-alone lightning protection devices. The cable trough and cable protection pipe of the instrument enter the control room and should be connected with the lightning protection induction grounding device of the electrical profession. The lightning protection device in the control room should be connected to the lightning protection induction grounding device of the electrical profession. In the lightning protection grounding place where the instrument cable protection pipe and the instrument cable armor layer are required for lightning protection, it should be connected to the lightning protection induction grounding device of the electrical profession. The spare core of the unshielded multi-core cable outside the lightning strike area should be connected to the shield ground. For shielded cables whose shielding has been grounded or cables that are laid through steel pipes or in metal cable troughs, the spare core may not be grounded.
