What is electrical switchgear?

The switchgear consists of one or more low-voltage switchgear and related control, measurement, signal, protection, adjustment and other equipment. The manufacturer is responsible for the completion of all internal electrical and mechanical connections and the complete assembly of structural components.

The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and electrical energy conversion in the power system. The structure of the switchgear is roughly similar, mainly divided into busbar room, circuit breaker room, secondary control room (instrument room), feeder room, each room is generally separated by steel plates. Internal components include: bus (busbar), circuit breaker, conventional relay, integrated relay protection device, measuring instrument, isolating knife, indicator light, grounding knife, etc.
