Product name:
EVS1P-12 series indoor high-voltage AC vacuum circuit breaker
Product introduction:
This series of vacuum circuit breakers is a three-phase AC 50Hz, rated voltage 12-24kV indoor high-voltage switchgear, which can be used for industrial and mining, enterprises, power plants and substations for the control and protection of electrical facilities.
Product features:
1. Long life, simple maintenance, no pollution, no explosion hazard, low noise, frequent operation;
2. EVS1P-12/T1250-31.5 vacuum circuit breaker arranges the arc extinguishing chamber and the operating mechanism on a special-shaped frame, that is, an integral layout. This structural design can make the operating performance of the operating mechanism more consistent with the required performance of the arc extinguishing chamber opening and closing, reduce unnecessary intermediate transmission links, reduce energy consumption and noise, make the circuit breaker's operating performance more reliable, and users can directly put it into operation without adjustment.
3. The main circuit of the circuit breaker adopts a sealed pole structure. The vacuum interrupter is longitudinally sealed in a tubular insulating tube, which is cast from epoxy resin using the APG process. This structural design not only prevents the vacuum interrupter from being damaged by external factors, but also ensures that it can present a high resistance state to the voltage effect even in a hot and humid environment and a severely dirty environment.
4. The new high-reliability lightweight spring mechanism, the secondary part is modularly designed and a secondary wiring board is added, making the wiring more beautiful and neat.
