The study of lightning-protection grounding for power dispatchingand communication equipment

摘要

Because of irrational grounding, the normal work of dispatchingand communication equipment is affected heavily, equipment can even bedestroyed. The grounding problem for power dispatching and communicationequipment in microwave buildings is analyzed in the paper. A comparisonbetween separated and common grounding in different cases is made. Anoptimal grounding scheme is proposed according to the actual situation.This is of practical significance and theoretical study value forlightning-protection and anti-interference for specially sensitiveautomation equipment to the outside interference
