The utility model relates to a colliery distribution device especially relates to a vacuum circuit breaker is directly driven in colliery flame proof solid -sealed type phase separating. Including vacuum interrupter and permanent magnetic mechanism, vacuum interrupter is solid -sealed type utmost point post, solid -sealed type utmost point post is every to be equipped with a permanent magnetic mechanism mutually, promptly vacuum circuit breaker with three permanent magnetic mechanism respectively with solid -sealed type support connnection extremely, permanent magnetic mechanism and solid -sealed type extremely are connected through insulating pull rod and actuating lever between the post. The utility model discloses the core material magnetic conductivity is good, installs smallly, and simple structure, transmission link are few, and it is little that the tolerance is moved to accumulative total, and interaction time dispersibility is little, can be according to the locating information of three -phase branch, close a floodgate constantly voltage or electric current phase angle, and the operation is closed to the synchronization pass of realizing high voltage circuit breaker, establishes the basis for the intellectuality of colliery flame proof equipment, simultaneously, permanent magnetic mechanism adopts the hybrid power supply mode, and it provides sufficient energy, the equipment of having guaranteed reliable operation when power system fault to operate for the circuit breaker.
