ABSTRACT:
A force-storing unit for a tap changer has an output shaft journaled in a support and a pair of parallel guide rods fixed on the support, defining a longitudinal direction, and spaced parallel to the shaft. A force-storing slide and an output part are displaceable longitudinally along the rods between respective end positions. Teeth on the output part mesh with a gear carried on the output shaft. Mechanism between a drive shaft and the slide displaces the slide longitudinally on the rods in a direction dependent on a rotation direction of the drive shaft and loads a spring between the slide and the output part as the slide is moved longitudinally relative to the output part. A latch connected between the slide and the output part retains the output part in each of its end positions until the slide moves into the respective end position.
