Power accumulator for on-load tap changer, has lift and leaping carriages with three linear bearings, and cam follower coinciding with actuator such that leaping carriage is pushed into new final position by rotation of eccentric plate

摘要

The accumulator has longitudinally movable lift and leaping carriages (3, 16) fixed in connection with a drive shaft, where the carriages are guided through three parallel guide rods extending in the direction of motion of the carriages. Two of the three rods are surrounded by a power accumulator spring, and each of the carriages has three linear bearings, where each of the bearings surrounds the other rod. A cam follower (29) is arranged to coincide with an actuator such that the leaping carriage is pushed into a new final position by rotation of an eccentric plate.
