12KV Vacuum Circuit Breakers
(VS1)
VS1 series indoor high voltage
AC vacuum circuit
breakers are indoor switching equipment with rated
voltage of 12kV. It can be used for the control and protection of
electrical facilities in industry and mining, buildings and
substations, as well as in places with frequent operation. The
products have high reliability and
stability.
The vacuum circuit
breaker is equipped with low power consumption modular
spring operating mechanism to meet the requirements of electric
and manual operation. After the mechanism stored energy, the
closing operation is completed after receiving the closing signal
or pressing the closing button by hand; After the closing action
is completed, after receiving the opening signal or press the
opening button by hand to complete the opening
operation.
Ambient air temperature range: -5° C to 40 ° C,
in addition, average temperature measured in 24 hours does not
exceed 35° C.
Altitude <=1000m.
Daily average relative humidity should not
exceed 95%. Daily average water vapor pressure should not exceed
2.2kpa;
Monthly average relative humidity should not
exceed 90%. Monthly average vapor pressure should not exceed
1.8kPa.
Keep away from fire, explosion, serious
pollution, chemical corrosion and violent
vibration.
Vacuum
interrupter
Vacuum interrupter adopts the world's advanced
manufacturing technology of miniaturized and high-performance
interrupter;
