Structural Features
1.Xgn2-12 switchgear is a metal-enclosed box structure, and the cabinet frame is welded by angle steel and copper plate.
2.The cabinet is divided into a circuit breaker room. bus room. cable room and relax room. and each room is separated by a steel plate.
3. The front and rear doors of the switchgear are installed off the wall and maintained on both sides
4. There is a pressure relief channel on the ton of the switch cabinet. In case of an internal arc fault. the pressure and gas can be released from the pressure relief channel to ensure the safety of operators.
5. The switchgear has perfect and mature "mechanical five prevention" and simple and clear operation procedures
6.ZN28A-12 ZN63A-12. VS1 and other series vacuum circuit breakers are used as the main circuit breaker of the switch cabinet. Other types of circuit breakers can also be equipped as required Ct19 spring operating mechanism
7. The disconnector adopts gn30-10 rotary disconnector and gn22-10 high current disconnector.
XGN2-12 Fixed AC metal-enclosed switchgear
XGN2-12 Fixed AC metal-enclosed switchgear, used as indoor complete distribution equipment for receiving and distributing electric energy in a three-phase AC 50/60Hz system with rated voltage 3.6-12kV. It has the function of circuit protection and detection. Its bus system is a single bus and single bus with bypass bus and can be derived from, double bus structure.
The switchgear conforms to the requirements of national standards GB3906 and DL/T404 and has a complete set of reliable performance, complete. functions, simple structure, convenient operation of the mechanical anti-error locking device, simple and effective to meet the "five" locking function requirements proposed by the two.
