Vacuum circuit breaker HVD1 12KV 1250A 25KA VCB with copper parts 210 mm phase distance
HVD1-12 (VS1-12) Type Indoor AC HV vacuum circuit breaker (hereinafter referred to as circuit breaker) is suitable for 12kV air-insulated indoor switches, used as a protection and control unit for power equipment of industrial and mining enterprises. Thanks to super perfection, this is especially for locations where frequent operation of the rated operating current or multi current short circuit breaking is required.
The circuit breaker adopts the integrated design of the working mechanism and the body of the circuit breaker, servers as not only a fixed installation, but also a cart block through equipping with a special breakout mechanism.
2. Operating conditions
3.1 ambient temperature: -15 ℃ ~ + 40 ℃;
3.2 Environmental humidity: daily average Relative humidity: 95%, monthly average Relative humidity: 90%; daily average saturated vapor pressure: 2. 2 × 10-3 MPa, monthly average saturated vapor pressure: 1. 8 × 10-3Mpa;
Height 3.3: no more than 1000 m;
3.4 earthquake intensity: does not exceed & degree;
3.5 duty station: lack of water, flammable or explosive substances, chemical corrosive gas or sudden vibration.
