XGN2-12KV Inlet and outlet equipment of metal closed box combined switchgear

Introduction of metal closed box combined switchgear

XGN2-12 box-type fixed metal closed box combined switchgear (referred to as switchgear) is used for receiving and distributing electric energy in 3.6, 7.2, 12kv three-phase AC 50Hz systems, suitable for frequent operation occasions, and its busbar system is a single busbar (and can be derived single bus with bypass and double bus structure).

The switchgear meets the requirements of the national standard GB3906-91 (3-35kv AC metal-enclosed switchgear) and the national standard IEC298, and has two proposed “five-proof” locking functions.

The main switch of the switch cabinet adopts ZN28-12 series vacuum circuit breaker, equipped with CDI7 series electromagnetic operating mechanism or CT19 series spring operating mechanism, and the isolating switch adopts GN30-12 rotary isolating switch or GN22-12 high current isolating switch series.
