Novel direct push type first-phase single-open phase selection magnetic control circuit breaker

The invention relates to a novel direct-push type first-phase single-open phase-selection magnetic control circuit breaker, which belongs to the technical field of operating mechanisms of high-voltage switches and comprises three pole columns, a first open pole mechanism, three connecting movable joints, a second open pole mechanism, a parallel plate, a fixing screw, a reinforcing connecting plate, an insulator and an arc extinguish chamber, a reinforcing connecting plate is arranged on the pole re-opening mechanism, a parallel plate is fixed on the reinforcing connecting plate through a fixing screw, one end of the parallel plate is connected with the insulator of the second pole column through a second connecting movable joint, and the other end of the parallel plate is connected with the insulator of the third pole column through a third connecting movable joint. By arranging single-phase and double-phase on-off, ideal type selection on-off can be achieved, the cost can be reduced, on the other hand, time
