ZN63A(VS1)-12 Series of Indoor High Voltage Vacuum Circuit Breaker
General Description:
ZN63A(VS1)-12 Model indoor high voltage vacuum circuit breaker applies to power system of rated voltage 12kv as a protective and control unit for power grid equipment and industrial power equipment It can equip with KYN28(GZS1), XGN, GG-1A and other types of switchgear panels. Related products: isolated handcart, fuse handcart and voltage transformer handcart
Structural Features：
1.This series of VCB is used Integrated design for operating mechanism and VCB body with reasonable, beautiful and compact arrangement.2.This series of VCB adapted vertical insulation house against Impact due to different weather, it can effectively prevent VIS against damage by exterior factors.3.The two different installation unit of Fixed type and withdrawable type can meet the different requirements for different switchgear.
Applying Ambient Conditions:
Ambient temperature:-10℃-+40℃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％.Earthquake intensity: not exceed 8 degrees.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 moreThan1.8Kpa;The height above sea level:≤1000 m (Except special requirements)It should be installed in the places without fire, explosion, serious filth, and chemical erosion and violent vibration.
