VS1-12 indoor high voltage vacuum circuit breaker
product information
Product name: VS1-12 indoor high voltage vacuum circuit breaker
Category: high voltage components
Product introduction: VS1-12 indoor high-voltage vacuum circuit breaker is an indoor switchgear with a three-phase AC 50Hz rated voltage of 12KV power system. It is used as a protection and control unit for power grid equipment and industrial and mining enterprise power equipment. It is suitable for places requiring frequent operation under the rated working current, or where there is more switching and breaking short-circuit current.
The main purpose of VS1-12 indoor high voltage vacuum circuit breaker
VS1-12 indoor high-voltage vacuum circuit breaker is an indoor switchgear with a three-phase AC 50Hz rated voltage of 12KV power system. It serves as a protection and control unit for power grid equipment and industrial and mining enterprise power equipment. It is suitable for places requiring frequent operation under the rated working current, or where there is more switching and breaking short-circuit current.
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 it can be equipped with a dedicated propulsion mechanism to form a handcart unit.
Applicable environment of VS1-12 indoor high voltage vacuum circuit breaker
a Ambient air temperature: upper limit +40℃. Lower limit -15℃;
b Altitude: ≤1000m (if the altitude needs to be increased, the rated insulation level shall be increased accordingly);
c Amplitude: the seismic intensity does not exceed 8 degrees;
d The daily average value of air relative humidity is not more than 95%, and the monthly average value is not more than 90%
e Places with fire, explosion hazard, severe pollution, chemical corrosion and severe vibration.
