Details of Product:
Indoor high voltage vacuum circuit breaker (circuit breaker) is suitable for indoor switchgear of 12kv power system. As a protection and control unit for power grid equipment and industrial and mining enterprise power design, it is suitable for switching various loads of different nature, frequent operations, and multiple interruption of short-circuit current.
The product adopts a new type of circuit breaker operating mechanism
1. The primary part of VSC can use solid-sealed pole poles of international brands, and the vacuum interrupter and main conductive circuit parts can be solid-sealed into a whole
2. Protect the interrupter from impact, dust and condensation
3. Strong environmental adaptability, greatly reducing operation and maintenance costs
4. The operating mechanism is integrated with the circuit breaker body, which has been verified by type tests
5. With E2 electrical life, M12 mechanical life
Environmental requirements:
1. Ambient temperature: highest temperature + 4O℃, lowest temperature -15℃
2. Environmental humidity: daily average relative humidity ≤95%, monthly average relative humidity: ≤90%, daily average vapor pressure ≤22×10-3MPa, monthly average vapor pressure ≤1.8×10-3MPa.
3. Altitude: not more than 1000m;
4. The earthquake intensity does not exceed 8 degrees;
5. The surrounding air is not significantly polluted by dust, smoke, corrosive and/or flammable gas, steam or salt spray.
Note: If it exceeds the requirements of the above normal use environmental conditions, it is necessary to negotiate with the manufacturer.
