Product Description

1. ZN85 type 3 phase 40.5KV 33kv hardcart type draw out vacuum circuit breaker

 

Zn85-40.5 / t2000-31.5 indoor high voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker), suitable for three-phase ac 50Hz, rated voltage 40.5kv power system, for industrial and mining enterprises, power plants and substations as load current, overload current, fault current.

 

The circuit breaker and operating mechanism adopt upper and lower arrangement structure, which effectively reduces the depth of the circuit breaker.

 

The spring operating mechanism specially designed for this new type of circuit breaker is installed in the framework of the circuit breaker. Its structural characteristics are more suitable for the upper and lower layout of the circuit breaker and become an integral part of the overall structure of the circuit breaker.The mechanism design is simple, the output curve and its performance are more suitable for the characteristics and requirements of 40.5kv vacuum circuit breaker.

 

The circuit breaker is suitable for frequent operation and a variety of occasions and operating conditions are harsh places.

 

2. Environmental conditions:

 

1. Ambient temperature: no higher than +40℃, not lower than -25℃;

2. Altitude: the altitude does not exceed 2000m;

3. Relative humidity: the daily average does not exceed 95%, and the monthly average does not exceed 90%;

4. Earthquake intensity: no more than 8 degrees;
