Product Description
The ZN85-40.5 series indoor high-voltage vacuum circuit breaker (hereinafter refered 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 curent, overload current, and fault curent in industrial and mining enterprises, power plants, and substations. The circult breaker and operating mechanism are arranged vertically,effectively reducing the depth of the circuit breaker.
The three-phase arc extinguishing chamber and assoclated charged body are isolated by three independent epoxy resin insulation cylinders, forming a composite insulaion 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 the insulation cylinder, with a phase spacing of only 300mm. The main circuit electrical connections are all fixed connections, which have high reliability. The insulation cylinder is installed above the circuit breaker frame.
The spring operated mechanism specially designed for this new type of circuit breaker is installed inside the circuit breaker frame.and its structural characteristics are more suitable for the upper and lower layout of the circult breaker, and become an integral part of the overall structure of the circuit breaker.The mechanism design is simple, and the output curve and its performance are more suitable for the characteristics and requirements of 40.5kV vacuum clrcuit breakers. The overall layout is reasonable, beautiful, and concise Smal size., fexible operation, reliable electrical performance, long service life, easy maintenance, and maintenance free mechanism This circuit breaker is suitable for frequent operation, various occasions, and places with harsh operating conditions.
