Product name:
EVS1P-12 series two-phase indoor high-voltage AC vacuum circuit breaker
Product introduction:
This series of vacuum circuit breakers is a two-phase AC system with a rated voltage of 12kV indoor high-voltage switchgear, which can be used for control and protection of electrical facilities in factories, mines, enterprises, power plants and substations.
Product features:
The EVS1P-12 series two-phase indoor high-voltage AC vacuum circuit breaker arranges the arc extinguishing chamber and the operating mechanism on a special-shaped frame, that is, an integral layout. The circuit breaker can be installed in both a trolley-type switch cabinet and a fixed switch cabinet. The main circuit adopts a composite insulation pole structure. The vacuum arc extinguishing chamber is longitudinally sealed in a tubular insulating cylinder, which is cast by epoxy resin using APG process;
The operating mechanism is an independent spring energy storage type with manual and electric energy storage functions. The operating mechanism is placed in the chassis in front of the arc extinguishing chamber and is a splint-type structure.
