ELECTROMAGNET DRIVING MECHANISM, ASSEMBLY AND DUAL POWER AUTOMATIC TRANSFER SWITCH

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.
