Abstract: The circuit breaking safety lock includes a slider, a first locking piece, a first locking shaft, a first pressure spring and a first lifting mechanism, wherein the first locking piece is fixedly connected with the slider, the first locking shaft is locked with the first locking piece, the first pressure spring is used for moving the first locking shaft along a direction towards the slider, and the first lifting mechanism is used for moving the first locking shaft along a direction away from the slider. The double-power switch includes a housing, a first position electrode, a second position electrode, a movable electrode, a bi-position lock and the circuit breaking safety lock, wherein the movable electrode is fixedly connected with the slider and moves between the first position electrode and the second position electrode with the slider.

Abstract: The invention discloses a quick arc-breaking circuit-breaker, comprising two electrode contacts for switching on and switching off a circuit, and a plurality of partition plates arranged between the two electrode contacts and configured in such a way that, when the two electrode contacts are separated, the partition plates are inserted at the fastest speed between the two electrode contacts, to quickly break the arc and stop burning. As the partition plates of the quick arc-breaking circuit-breaker are inserted between the two electrode contacts from different directions, the breaking and insulating speed is accelerated, the isolation and sealing effects between the two electrode contacts are enhanced, and the insulation and arc extinguishing effects of the circuit-breaker are thus improved. The circuit-breaker of the invention has a simple structure and a low manufacturing cost.

Abstract: A circuit breaker with quick response and separation and a quick response and separation method for the circuit breaker. The circuit breaker comprises a breaking contact group and a joint contact group. The breaking contact group comprises a movable breaking contact. The joint contact group comprises a movable joint contact. A movable contact limiting device used for limiting moving positions of the breaking contact and/or the joint contact is arranged between the breaking contact group and the joint contact group. The quick response and separation method for the circuit breaker comprises a breaking and opening step, wherein the breaking contact moves in a reverse direction and is separated independently ahead of the joint contact, or the breaking contact and the joint contact both move in a reverse direction and are separated at the same time.
