ZN85-40.5 series indoor high-voltage vacuum circuit breaker
Short Description:
The ZN85-40.5 series indoor high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is suitable for use in three-phase AC 50Hz, rated voltage 40.5kV power systems, and can be used for load current, overload current, and fault current in industrial and mining enterprises, power plants, and substations. The circuit breaker and operating mechanism are arranged vertically, effectively reducing the depth of the circuit breaker. The three-phase arc extinguishing chamber and associated charged body are isolated by three independent epoxy resin insulation cylinders, forming a composite insulation structure. The circuit breaker meets the requirements of air distance and creepage distance under normal operating conditions, and effectively reduces the volume of the circuit breaker. The main electrical circuit vacuum arc extinguishing chamber and the dynamic and static conductive connection are installed inside an insulating cylinder, with a phase spacing of only 300mm
