摘要： An operating mechanism for a dual power supply changeover switch and a dual power supply changeover switch are provided. The operating mechanism includes: a first supporting plate and a second supporting plate which are parallel to each other and spaced apart from each other; a plurality of first supporting members configured to fix the first supporting plate and the second supporting plate together; a first electromagnet assembly and a second electromagnet assembly which are symmetrically mounted on the first supporting plate and the second supporting plate about a symmetry plane; and an output assembly mounted on the first supporting plate and the second supporting plate along a rotation axis in the symmetry plane, the output assembly is capable of rotating around the rotation axis and has a first driving rod, the first driving rod protrudes from the second supporting plate and is connected to a movable contact carrier. The first electromagnet assembly and the second electromagnet assembly are configured to drive the output assembly to rotate in a first direction and a second direction which are opposite to each other, respectively, and hence to drive the movable contact carrier of the dual power supply changeover switch to rotate by the first driving rod.

摘要： 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.

摘要： Disclosed are an electromagnet driving mechanism 100, an electromagnet driving assembly and a dual power automatic transfer switch. The electromagnet driving mechanism comprises: a mechanism frame 140; a stationary core 130; a movable core 120, including a moving stroke between a first position away from the stationary core and a second position in contact with the stationary core, the moving stroke including an approaching stroke section; a coil, configured to generate a magnetic attraction force between the stationary core and the movable core upon being energized to drive the movable core to move towards the second position; a reset spring member 112; and a reset auxiliary assembly 150, including a push member 152 and a reset auxiliary spring 154. The reset auxiliary assembly applies a reset auxiliary spring force to the movable core in the approaching stroke section through the push member. The dual power automatic transfer switch includes: an electromagnet driving mechanism assembly; a first stationary contact and a second stationary contact; a movable contact; the electromagnet driving mechanism assembly drives the movable contact to move among a first contact position, a double-separation position and a second contact position.
