& Overview of indoor high-voltage vacuum circuit breaker:
outdoor high-voltage vacuum circuit breaker is an indoor switching device with three-phase AC rated voltage for power systems. It is used as a protection and control unit for power grid equipment and power equipment of industrial and mining enterprises. It is suitable for places requiring frequent operation under rated operating current or multiple short-circuit currents.
The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcart unit.
Environmental conditions for use:
Ambient air temperature: maximum ℃, minimum ℃
Altitude: no more than
Air humidity: maximum daily average relative humidity no more than %, monthly average The value is not greater than %
, the amplitude: the seismic intensity does not exceed excessive
, and there is no risk of fire, explosion, serious pollution, chemical corrosion and violent vibration.
