Abstract
A switch unit for switching over an onload tap changer. The switch unit has an on-load tap changer with an actuating shaft that actuates a switch; and a drive system with a motor. The drive system is mechanically coupled to and configured to actuate the on-load tap changer. The drive system is configured such that, when the on-load tap changer is actuated, the drive system uses the actuating shaft as a store for kinetic energy in such a way that the actuating shaft is accelerated and the switch is actuated by the kinetic energy from the actuating shaft and additional energy provided by the motor.
