Metal-Clad Closed Drawer Switchgear (XGN2-12)

XGN-12 high voltage alternating current metal-cased closed drawer switch device is suitable for 12KV three-phase AC power network of 50Hz. The device is extensive used for industry. Civil cable looped network and terminal power supply, especially for power receipt and distribution for urban residential community, secondary mini-power substation, switching station, industrial and mining enterprises, shopping mall, airport, subway, small and medium power station, hospital, stadium, railway, tunnel etc...The equipment is the newest metal closed switchgear use air insulation, and it has many advantages such as: Simple structure, flexible operation, easy installation, reliable interlocking and so on.

Performance features:
1. The device internally installed vacuum circuit breaker and use vacuum interrupter, which is maintenance-free with long operation life and the operation attempt can reach 10000 times. The enclosed load switch or fuse can be added according to the requirement of customer.
2. Adopt advanced and scientific design with small size.
3. An intelligent controller is provided, and it can set multiple functions such as the over current protection, quick-break protection, automatic trip with no-voltage, delayed automatic enclosure when power transmission, automatic reset when instantaneous fault take place and automatic lock when permanent fault take place etc. As well as upload every data at time.
4. An interlocking device is provided and it has the functions of preventing disoperation of circuit breakers, preventing pushing or pulling truck with load, preventing closing earth switch under voltage, preventing supplying power when earth switch is at the earth position and preventing entering the electrical separation zone by accident.
5. The top and underneath isolating switch both adopt GN30-10(D)rotary isolating switch series which with dual fracture (the underneath isolator of switchgear, which rated current is 3150A, adopts GN22-10 non-rotating isolating switch series).

Working conditions:
