XGN2-12 series of box type fixed metal closed switch cabinet is used in the power system of 3.6~12kV three-phase AC 50Hz as the occasion between power receiving and distribution, especially for frequent operation. Its bus system is a single bus system, and it can derive a single busbar with bypass structure.
The main switch of this switch cabinet adopts ZN28A-12, ZN28-12, and VS1, VS4, VSM permanent magnetic mechanism series vacuum circuit breaker, and the isolation switch uses GN30-12 series.
The switchgear is a metal enclosed box structure. The cabinet body is made of steel plate by numerical control equipment. Finally, it is assembled by bolted connection. It can also be assembled by standard profile. The cabinet has high accuracy and beautiful appearance. The cabinet structure is divided into the circuit breaker room, the busbar room, the cable room and the relay room, and the plate is separated by the plate between the room and the room. The circuit breaker chamber, the bus room and the cable room have a pressure release channel. If the internal fault occurs, the gas can be released through the exhaust passage. The busbar is in the upper part of the cabinet, and the busbar is arranged in shape. Switch cabinet for double maintenance, maintenance of the two front components, maintenance operation mechanism, mechanism of linkage and transmission part and a circuit breaker; behind the maintenance bus and cable terminal. The circuit breaker room and the cable room are equipped with light. The switchgear meets the standard requirements such as GB3906, IEC298 and so on.
