Abstract
The utility model discloses a novel vacuum circuit breaker which comprises an operating mechanism box, a three-phase vacuum circuit breaker, an insulating partition. The three-phase vacuum circuit breaker comprises a vacuum arc extinguish chamber, an inlet terminal, an outlet terminal and an insulating support rod. The novel vacuum circuit breaker further comprises a hollow insulating porcelain sleeve. One end of the insulating porcelain sleeve is connected with the operating mechanism box, and the other end is provided with a first inlet/outlet hole. The middle part of the insulating porcelain sleeve is provided with a second inlet/outlet hole. The three-phase vacuum circuit breaker is arranged in the insulating porcelain sleeve. The inlet terminal and the outlet terminal are respectively arranged in the first inlet/outlet hole and the second inlet/outlet hole. The insulating porcelain sleeve is further provided with an insulating pull rod. One end of the insulating pull rod is connected with the operating mechanism box, and the other end is connected with the insulating porcelain sleeve. According to the utility model, the structure is simple; the insulating partition is arranged between the three-phase vacuum circuit breaker; the novel vacuum circuit breaker further comprises the insulating porcelain sleeve; the three-phase vacuum circuit breaker is arranged in the insulating porcelain sleeve; the insulating performance of the circuit breaker is improved; and the use safety performance and the stability are improved.
