Abstract
The utility model relates to a high-pressure vacuum circuit breaker. The structure of the utility model is that a mono-coil permanent magnetic device is connected with a principal axis of a vacuum arc distinguishing chamber with a medium lever member. The principal axis of the permanent magnetic device is connected with the principal axis of the vacuum arc distinguishing chamber with a medium drawplate. Two sides and middle of the drawplate are provided with rotating shafts. The principal axis of the vacuum arc distinguishing chamber, at a location that is corresponding to an insulating tie bar, is respectively provided with connecting levers. Two sides are connected with the principals and the insulating tie bar through the rotating shafts. The permanent magnetic device operating the vacuum circuit breaker is connected with a moving contact of the 3-phase vacuum arc distinguishing chamber with the drawplate and the connecting lever, realizing the turning on/off. The utility model has the advantages that the structure is simple, the installment is convenient; the friction force of the members of the vacuum circuit breaker is reduced, the structure is impact, the lever can be operated flexibly and moved stably because the permanent magnetic device is connected with the principal axis of the arc distinguishing chamber through the drawplate by using the lever structure.
