ZN39-405C Indoor High Voltage Vacuum Circuit Breaker

Description:

ZN39-40.5C indoor high voltage vacuum circuit breaker mainly serves in mineral enterprise,power plant,substation for control and protection of electric equipment.

  • Product Description

Summary
1.Circuit breaker with composite insulation, circuit breaker under the condition of meet the normal operation of the air distance and the creepage distance requirements,and effectively laughed the volume of circuit breaker, the overall layout is reasonable, beautiful and concise.
2.Operating mechanism used specifically for this new type of circuit breaker design of spring operating mechanism, the output curves to the demands of the arcing chamber cooperate good, its performance is more suitable for the characteristics and requirement of 40.5 KV vacuum circuit breaker,it has the very high reliability, long service life, convenient maintenance and maintenance free.
3.Handcart adopt four cylinder nut mechanism, propulsion can easily move the handcart, use force mechanical locking mode, meet the “five prevention” function.
Applicable to a variety of occasions and is quite harsh operating conditions of the workplace.

Ambient condition
1.The environment temperature:It is not higher than 40 °C ,Not less than -10 °C.
2.Relative humidity:Daily average no greater than 95%, on average no greater than 90%
Earthquake intensity:No more than 8 degrees.
3.Vapor pressure: daily average no more than 2.2 Pa, monthly average no more than 1.8 Pa
4.Altitude: not more than 1000 m.
5.No fire and explosion danger, serious pollution, chemical corrosion and the site of violent vibration.
