OPERATION MECHANISM FOR DUAL-POWER AUTOMATIC TRANSFER SWITCH AND DUAL-POWER AUTOMATIC TRANSFER SWITCH

An operation mechanism for a dual-power automatic transfer switch and a dual-power automatic transfer switch. The operation mechanism includes: a frame; a rotating disk, rotatably mounted to the frame; a first elastic member, wherein one end of the first elastic member is configured to abut against the rotating disk, and the other end of the first elastic member is mounted to the frame; a driving disk, configured to rotate in cooperation with the rotating disk when the rotating disk rotates; a driving rod, mounted on the driving disk and configured to rotate together with the driving disk and connected with a movable contact bracket, wherein at the dual-off position of the dual-power automatic transfer switch, when the rotating disk rotates in a first direction, the first elastic member deforms to store energy, and after the rotating disk rotates by a predetermined angle, the rotating disk abuts against the driving disk so that the driving disk also rotates in the first direction, then the first elastic member passes through a "dead point", and the rotating disk and the driving disk continue to rotate in the first direction under an action of the first elastic member, so that the driving rod rotates in the first direction and drive the movable contact bracket to rotate, so as to realize a switching of the dual-power automatic transfer switch from the dual-off position to the first power-on position.
