Application scenarios	Used in 3.6, 7.2, 12kV three-phase AC 50Hz system to receive and distribute electric energy

Overview

XGN7-12 box fixed type metal-enclosed switchgear (switch cabinet for short)is used to receive and distribute electrical energy in 3. 6, 7. 2, 12kV three phase AC 50Hz system, specially in the frequent operation occasion, its busbar system is single busbar (it can derive single busbar with branch and double busbar structure).
This switch cabinet conforms to the requirement of national standard GB 3906-91“3-35kV AC Metal-enclosed switchgear” and the international standard IEC 298, and has the function of “five prevention”.
This switch cabinet’s main switch adopts ZN28A-12 or the ZN22-12 series vacuum circuit breaker, equipped with CD17A electromagnetic operating mechanism and CT19B spring operating mechanism. Disconnecting switch adopts GN30-12 rotary type and GN22-10 heavy current series products.
