FORCE ACCUMULATOR FOR AN ON-LOAD TAP CHANGER

摘要

The invention relates to a force accumulator for an on-load tap changer. The force accumulator has a first gear arranged on a rotatable drive shaft. The first gear drives a crank by means of at least one additional gear. The crank is mechanically connected to an elastic element, which can be tensioned when a drive element is heated up. An output element can be triggered after the elastic element has been tensioned and swivels abruptly. The drive element is a rocker. The rocker has a first rocker roller and a second rocker roller, which alternately actuate a first pawl and a second pawl. A first detent position and a second detent position are associated with the first pawl on the output element and likewise a first detent position and a second detent position are associated with the second pawl on the output element, such that the first pawl and the second pawl are alternately in the first detent position and in the second detent position, in dependence on the position of the rocker.

1. A force accumulator for an on-load tap changer, with a first gear that is provided on a rotatable drive shaft and that drives a crank by way of at least one further gear, wherein the crank is mechanically connected with a resilient element that can be loaded when the drive element is drawn up and wherein a drive output element after loading of the resilient element can be triggered and abruptly pivots,
wherein the drive element is a rocker that comprises a first rocker roller and a second rocker roller respectively actuating in alternation a first latch and a second latch, a first detent position and a second detent position are associated with the first latch at the drive output element, and a first detent position and a second detent position are associated with the second latch at the drive output element so that the first latch and the second latch are disposed in alternation in the first detent position and the second detent position in dependence on the setting of the rocker.
