ZN12-12 Series of Indoor HV Vacuum Circuit Breaker

General Description
ZN12-12 series of indoor high voltage vacuum circuit breaker is three phase A.C.50(60) Hz indoor high voltage distribution equipment with 12kV rated voltage and below.This is characterized by simple construction,stroing breaking capability,long life with complete operating functions and convenient maintenance.It is suitable for controlling and protecting transmission and distribution system such as power generation plant and substation,especially used in the filed where it is frequently operated.
This kind of vacuum circuit breaker can be used for fixed switchgears(XGN2 and GGIA),it also can be equipment with truck used for varies panels like JYN2,KYN1 and kny49 as well as used for reconstruction for old-fashioned oil switchgear.
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.
