ZN85-40.5 33kV Indoor Vacuum Circuit Breaker 33KV Draw Out VCB
ZN85-40.5 series indoor high-voltage vacuum circuit breaker is a kind of three-phase indoor high-voltage switchgear of rated voltage 40.5kV and AC 50Hz, equipped with a special 3AV3 spring structure. It can be configured in JYN1-40(Z) moving-off metal-enclosed switchgear, also can be configured in KYN61-40.5(Z) assembly type metal-closed switchgear to use. It is the best ideal circuit breaker of 40.5 kV device.
The series of products have the characteristic high technology parameters, strong breaking ability, reliable operation, stable performance, long service life, convenient maintenance, and no explosion danger and pollution. It is used for control and protection of electric facilities, such as industrial and mining enterprises, power plant and substation for single generatrix system. It is also suitable for occasions where require frequent operation and other special occasions of suit capacitors, etc.
Circuit breaker is of integration and modular design. Its overall structure is simple and reasonable, using up and down decoration, arcing chamber part up in it and operating mechanism down. It uses the special 3 AV3 spring operation mechanism which need no adjustment, and whose movement is stable and reliable. Vacuum arcing chamber decorates in closed insulation cylinder which improves the insulation performance and reduce the overall size.
