Medium voltage vacuum circuit breaker for indoor 10kV 12kV MV high voltage withdrawable switchgear

VSG vacuum circuit breaker for indoor switchgear is suitable for 12kv power system, as a protection and control unit for power equipment, industrial and mining enterprises, and can be used for breaking various loads and occasions where frequent operations and repeated breaking short-circuit current. . This product adopts a new type of circuit breaker, the VSG part can adopt the pre-embedded pole of the international brand, the vacuum interrupter and the main circuit part are fixed and sealed as a whole, and the interrupter is protected from collision, dust and gel images, and the ability is strong Adapt to the environment and greatly reduce operation and maintenance costs. It has truly realized the operation mechanism of part maintenance-free and low-maintenance of the product; the design of the operating mechanism and the circuit breaker body has passed the type test, and the mechanical and electrical life of E2 level and M2 level.
