ZN85-40.5 indoor MV vacuum circuit breaker (hereinafter referred to as circuit breaker), suitable for three-phase AC 50Hz, rated voltage 40.5kV power system, can be used for industrial and mining enterprises, power plant and substation as opening and closing load current, overload current, fault current use. Circuit breaker and operating mechanism adapt the upper and lower arrangement of institutions, effectively reducing the circuit breaker depth.
Three-phase arc extinguishing chamber and associative charged body is isolated by three independent epoxy resin insulating cylinder, composite insulating structure, The circuit breaker meets the air distance and creepage distance requirements under normal operating conditions,and effectively reduces the volume of circuit breaker. The vacuum interrupter of the main current ring and the dynamic and static conductive connections are installed in the insulating cylinder with a distance of only 300mm.The electrical connection of the main circuit is fixed connection, which has high reliabilityhas the very high reliability. Insulating cylinder is arranged on the upper side of the circuit breaker frame.
The overall layout is reasonable, beautiful appearance, simple. It has the characters of small volume, flexible operation, with reliable electrical performance, long service life, convenient maintenance, maintenance free.
The circuit breaker is suitable for frequent operation, various occasions and places with harsh operating conditions.
