The invention relates to a driving mechanism of a dual-power automatic
transfer switch. The driving mechanism mainly comprises a driving
electromagnet assembly, a mounting bracket, a connecting plate, a push rod, a lever, an oscillating
deck, a
crank, a main switch rotating shaft, a connecting rod, a pin shaft, a rotating shaft, a first hinged shaft, a second hinged shaft, a connecting block, a shaft, a third hinged shaft and a fourth hinged shaft; the driving
electromagnet assembly is composed of a
magnet exciting coil, a dynamic iron core, a spring and a static iron core. The driving mechanism is characterized in that in the driving
electromagnet assembly,
linear motion in the horizontal direction of the dynamic iron core and the push rod is converted into
linear motion of the pin shaft in the vertical direction through the oscillating
deck, the lever, the connecting plate and the like, and
linear motion of the pin shaft is converted into swing of the main switch rotating shaft around the axis through the connecting rod and the
crank. Reciprocating swing of the main switch rotating shaft completes switching on and switching off actions of the whole switch. The oscillating
deck plays a role in changing the
motion direction. The lever plays a role in increasing thrust. A connecting rod
crank mechanism plays a role in self-locking and preventing reversion.
