Abstract
The utility model discloses a power driving mechanism used for a vacuum on-load tap-changer. The mechanism comprises a driving source, an accumulator and a gear transmission mechanism. The gear transmission mechanism comprises three groups of gear transmission assemblies. The accumulator comprises an eccentric mechanism and an energy storage spring. The driving source is connected with the eccentric mechanism through a first group of gear transmission assemblies. Through driving rotation of the eccentric mechanism, the energy storage spring is compressed. At a certain position, the energy storage spring is released so as to drive an external slide plate to carry out horizontal step motion. The driving source makes a driving shaft from top to bottom carry out rotation motion through a second group of gear transmission assemblies. The driving source makes an external pointer driving mechanism carry out rotation through a third group of gear transmission assemblies. The mechanism of the utility model combines the driving source and an energy storage mechanism into one body. A long shaft connection structure used in the prior art is eliminated.
