VS1-24 indoor high-voltage vacuum circuit breaker|Hongtuo Transformer Co., Ltd

summary:

VS1-24 indoor high-voltage vacuum circuit breaker │ fixed/sealed/handcart type is the indoor switchgear of three-phase AC 50Hz rated voltage 24kV power system, as the protection and control unit of power grid equipment and power equipment of industrial and mining enterprises. It is applicable to places requiring frequent operation or multiple breaking of short circuit current under rated working current.

The circuit breaker adopts the integrated design of operating mechanism and circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcart unit.

Normal use environment:

◇ Ambient air temperature: upper limit+40 ° C, lower limit - 15 ° C;

◇ Altitude: ≤ 1000m (if it is necessary to increase the altitude, the rated insulation level will be increased accordingly);

◇ Amplitude: the seismic intensity shall not exceed 8 degrees;

◇ The daily average value of the relative humidity of the air is not more than 95%, and the monthly average value is not more than 90% ◇ There is no fire, explosion hazard, serious pollution, chemical corrosion and violent vibration in the place.
