As preferably, described pole comprises vacuum interrupter and housing, and one end of stationary contact bar and movable feeler lever is positioned at vacuum extinction indoor.
As preferably, the top of described stationary contact bar is provided with radiator, and during vacuum interrupter work in pole, caloric value is large, if dispelled the heat not in time, can affect the service behaviour of vacuum circuit-breaker.
As preferably, be provided with several full skirts outside described insulated column, full skirt can increase the creepage ability of vacuum circuit-breaker.
As preferably, outside described insulated column, be uniformly distributed four full skirts.
As preferably, described insulated column inwall is provided with several boss, when after circuit breaker Long-Time Service, all not easily pile up large-area dirty at insulated column inner surface and outer surface, and when there is condensation, because the effect of boss and full skirt considerably increases creepage distance, improve the insulating properties of mechanism.
Beneficial effect: a kind of permanent-magnetic small-size vacuum circuit breaker of modularized ring main unit of the present utility model, drive movable feeler lever to move up and down thus separating brake and combined floodgate by connecting lever, structure is simple; The top of pole is provided with radiator, the heat of the vacuum interrupter that can leave timely, and due to the effect of full skirt and boss, enhances the creepage ability of insulated column greatly, improve the insulation property of insulated column.
Accompanying drawing explanation
