VSG indoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an indoor switchgear for 12kV power system. It is used as a protection and control unit for power grid equipment and industrial and mining enterprises. And occasions of frequent operation and multiple interruption of short-circuit current. The product adopts a new type of circuit breaker operating mechanism. The primary part of the VSG can use international brand solid sealing poles to seal the vacuum interrupter and the main circuit parts into a whole, protecting the arc quenching chamber from collision, dust and condensation. Strong environmental adaptability, greatly reducing the cost of operation and maintenance, truly realizing the product is partly maintenance-free, and the operating mechanism is less maintenance; the integrated design of the operating mechanism and the circuit breaker body, after type test verification, has E2 level electrical life, M2 class mechanical life can be used as a fixed installation unit, or can be equipped with a special propulsion mechanism to form a handcart unit. Among them, fixed circuit breakers can be added with corresponding interlocks to meet the requirements of XGN2, GG1A, GGX and other fixed cabinets need.
