XGN68-12 Box type fixed indoor AC metal enclosed ring switchgear
Xgn68-12 (f), xgn68-12 (F.R) and xgn68-12 (z) box type (indoor) AC metal enclosed switchgear (hereinafter referred to as switch cabinet) meet the national standard GB3906 "3 ~ 35kV AC metal enclosed switchgear" and GB 16926 "AC high voltage load switch ---- In addition, it has the "five prevention" locking function proposed by the two departments.
Product features
1. The vacuum load switch in the high-voltage room does not need to be repaired, and its operating mechanism rarely needs to be repaired;
2. Simple and reliable mechanical interlock, prevent misoperation, and the operation is simple and convenient;
3. Each functional unit is separated from each other, and an independent pressure relief channel is provided to prevent the expansion and spread of the fault;
4. The isolation fracture and cable terminal connection point can be easily observed through the observation window;
5. The secondary element room has plenty of space, easy wiring and plenty of space in the cable room, which is suitable for all kinds of conventional cable connection;
6. The fuse of combined apparatus can be taken out and replaced, which is simple and convenient.
7. It is small, only 50% of the volume of ordinary switchgear
