VSG/C-24 side-mounted indoor high-voltage vacuum circuit breaker is suitable for three-phase AC 50 (60) Hz, 24kV power system, for industrial and mining enterprises, power plants and substations as a switch between load current, overload current and fault current. It is suitable for frequent operation occasions. Widely used in power plants, power grids, petrochemicals, metallurgy, subways, airports, buildings and other projects.
Structural features
1. The circuit breaker adopts a modular operating mechanism and an integrated energy storage handle. The overall layout is reasonable, beautiful and simple;
2. The electrical components adopt a modular design, which is easy to disassemble and replace damaged electrical components;
3. The circuit breaker adopts solid-sealed poles, which improves the insulation performance of the circuit breaker;
4. High service life, the circuit breaker meets the M2 level of mechanical life and E2 of electrical life;
5. With excellent breaking performance, it can ideally fit inductive and capacitive loads;
Environmental conditions
1. Ambient temperature: upper limit +40°C, and the average value measured within 24 hours does not exceed 35°C; lower limit -15°C.
2. Altitude: no more than 1000m.
3. Relative humidity: the daily average value does not exceed 95%; the monthly average value does not exceed 90%;
4. Water vapor pressure: the daily average value does not exceed 2.2kPa, and the monthly average value does not exceed 1.8kPa;
5. The surrounding air is not obviously polluted by dust, smoke, corrosive or flammable gas, steam and salt spray
