ZN63A(VS1)-12 indoor high voltage vacuum circuit breaker
1.vacuum circuit breaker
2.Reliable and maintenance free
3.Long service life,non exploration
4.Short delivery time
ZN63A(VS1)-12 vacuum circuit breaker is a type of indoor power distribution equipment. It ‘s developed by bring in technical of ABB cooperation combining our domestic situation. It can be used in double deck cabinet, fixed cabinet for protecting and controlling in transformer substation and power system of industrial and mining enterprises. They are especially appropriate to oil forbidden, maintenance free, and frequent operation places, strictly stick to the stander of GB-1984,DL403and IEC No.56,No.694.
Main characters:
Operation mechanism and circuit breaker are combined together, making the layout reasonable, concision and beauty. Stereoscopic isolate cylinder can protect circuit breaker from influence outside. Thus it can be applied to every special condition.Handcart and fixed type meet the need of different mounting requirement.Maintenance free. Only a little cleaning or lubrication would be enough.Ambient condition
1 Ambient temperature: max +40°C min -15°C(conveyance under -30°C is allowed)
2 Altitude: ≤1000m
3 Relative humidity: daily average relative humidity: ≤95%; monthly average relative humidity≤90%; daily average saturated vapor pressure ≤2.2*10-3 MPa; monthly average value ≤1.8*10-3 MPa
4 Earthquake intensity: ≤8 degree
5 The installation should be free from fire, explosion, severe vibration, chemical corrosion and serious pollution
