VSG-12 Indoor High Voltage Vacuum Circuit Breaker (Modular mechanism)
VSG-12 vacuum circuit breaker is an indoor power distribution device in a three-phase AC system with arated voltage of 12kV and 50Hz. As a protection and control unit for power equipment,industrial and miningenterprises, it is suitable for various natures switching loads and frequent operation,multiple breaking short-circuit currents. The vacuum circuit breaker use a new operating mechanism and embedded pole ( the vacuuminterrupter and main electric circuit parts enclosed into a whole ) , to protect the vacuum interrupter from theeffects of colision, dust and condensation, environment adaptable, greatly reduces the operation maintenancecost, realize the product free maintenance, operation mechanism less maintenance;Unibody design, operatingmechanism and circuit breaker ontology through the type test, with E2 level electrical ife, 2 level mechanical lifecan be used as the fixed unit installation, also can match feed mechanism, form a handcart unit, fixed type circuitbreaker can increase the corresponding interlocking, to meet the reguirements of match XGN2, GG1A fixedswitchgear.
