Product Description
ZN12-40.5 Series of Indoor HV Vacuum Circuit Breaker

General Description

ZN12-12 series of indoor high voltage vacuum circuit breaker is with rated voltage of 40.5kV,three-three phase A.C.50(60) Hz indoor high voltage switch equipment.T he structure of this kind of circuit breaker is simple but with strong breaking capability;it is suitable for application in the mining industry,substations and power transmission and distribution systems for controlling and protecting the switch.Especially suitable foe the industry which requires frequently operations like metallurgy fields,electric arc steel plant to control and protect the equipment.This kind of vacuum circuit breaker can be assembled with truck which can be suitable for many kinds of switchgear such as JYN1,GBC etc

Structural characteristics:

1.The operating mechanism is introduced the technique of operating mechanism from Siemens 3AF vacuum circuit breaker,the operating mechanism is integrated with vacuum circuit breaker,with characteristics of short transmission routes,less chains and high transmission efficiency.
2.This operating mechanism adopts spring type,it can be operated by AC or DC,also can be operated by manual.

Applying ambient conditions

1.Ambient temperature:-15~+40ºC.
2.The height above sea level:≤1000m(besides the special requirements).
3.Relative humidity:the average humidity of a day should be no more than 95%;the average humidity of a month should be no more than 90%.
4.Saturated vapor pressure:the average pressure of a day should be no more than 2.2kPa:the  average pressure of a month should be no more than 1.8kPa.
5.Earthquake intensity:not exceed 8 degrees.
6.It should be installed in the places without fire,explosion,serious filth, chemical erosion and violent vibration.
