The switchgear consists of a cabinet, main switch (SF6 load switch or combination electrical appliances), grounding switch, meterl room, busbars, and other electrical and auxiliary components.
The cabinet is assembled from aluminum-zinc steel plates through modularization. A pressure relief channel is provided behind the cabinet to protect operators in case of internal faults.
The busbar room's busbar is covered with insulation and directly connected to the wiring terminals of the load switch. The three-
phase busbars are arranged vertically, allowing the switchgear to be easily expanded on both sides and facilitating layout changes.
The meter room is located at the top of the switchgear and can accommodate ammeters, voltmeters, indicators, and electricl operating mechanisms.
