Vacuum Circuit Breaker for Vqc in Substation

1, General Description:

The bank of capacitors vacuum switch ZN12-12/630-12.5J is mainly used in VQC device of substation 10Kv(6Kv) system or in breaking

capacitive loading site (where working actions happen frequently) of power filter. It adopts a modular construction, using flexible busbar

to connect between switches so its volume is small and it is convenient to install inside the cabinet.

2,plication Environment:

1),Air Temperature Around:-40ºC~+40ºC;

2),Altitude should not exceed 2000m. Please negotiate with factory when it is over 2000m.

3),Humidity: relative humidity: daily average value should not exceed 95%, month average value should not exceed 90%.

4),No corrosive, flammable or conductive dust or gas in surrounding medium.

5),Not allowed to install in serious dirtiness or strenuous vibration place.
