ZN85-40.5 Series indoor vacuum circuit breakers
Using the upper and lower circuit breaker and operating mechanism layout structure. 1 eff ectively reducing the circuit breaker depth.
Three-phase interrupter and associated live parts by the three independent isolated I epoxy insulating tube to form Composite insulation, circuit breakers under normal operating! conditions to meet the air distance and creepage distance requirements, and Eff ectively] reduces the size of the circuit breaker. Led and electric circuit interrupter installed in the static ] conductive connection Insulation barrel, magnitude and angle pitch of only 300mm. All main I circuit electrical connection fi xed connection, With high reliability. Insulation installed in the! circuit breaker frame above the cylinder.
The new circuit breaker designed for the spring actuator, installed in the circuit breaker I within the framework of Its structural features more suitable arrangement of vacuum circuit I breakers up and down, turn off a circuit breaker in the overall structure Inseparable part of the cut. Mechanical design is simple, the output curve is more suitable for vacuum circuit 40.5KV Device characteristics and requirements.
Overall layout is reasonable, beautiful, simple. Compact, fl exible operation, with electrica1 properties Reliable, long life, easy maintenance, institutional maintenance features.
Frequent operation of the circuit breaker and apply a variety of occasions and running conditions are harsh places.;
