[0002] The center-mounted high-voltage switchgear, full name is metal armored center-mounted removable switchgear, belongs to high-voltage power distribution equipment. Based on online monitoring of 10KV, the structure of the center-mounted cabinet is divided into three layers: the upper layer is the busbar and instrument room (isolated from each other), the middle layer is the circuit breaker room, and the lower layer is the cable room.
