ABSTRACT:
A compensating device, especially for railway car transformers, has a compensation receptacle including a fluid-carrying connection with the interior of the housing of the transformer. In the compensation receptacle, a compensating plate is movable along an adjusting axis under the influence of an accumulator, and is in engagement with the transformer oil carried in the compensation receptacle. A guide arrangement for controlling the movement of the compensating plate includes two sheathings slidable counter to one another. One sheathing is connected with the compensating plate. The other sheathing is connected with the stationary parts of the compensation receptacle. At least one of the sheathings cooperates with a detent surface on the compensating plate or on the compensation receptacle. The compensating device can be arranged in a railway car in the underfloor compartment. Even with high lateral or cross forces, the compensating device produces a continuously working fluid connection between the compensation receptacle and the transformer housing.
