The invention relates to a power storage switch contacts lost. A special subordination for diverter switches of transformers. Part of this arrangement, however, lies in the fact that in the case of a crawler spring / wiping a tilting base that is empty during the emptying of the storage tank on one side and on the other hand no post-pressure movable bolts are arranged and can be provided for a drive element nodding on a circular path,
The invention is therefore based on the object of providing a hydraulic device. A simple, operationally reliable Kraftspeicheranord-Lme such Kraftspeicheraiv.rdnung is to create for diverter switches, which is a play from the Swiss l'alenise'vift solution of the load limit switch known at the time 287 () S6, as explained below 3 ° causes the older energy storage system to have its greatest potential energy, and which ensures a reliable off-the drive or the triggering of I.astumsciial- solution of the switch even if the switching process takes place large mechanical tern for transformers with step windings as is well known, with the help of energy storage devices that have to be overcome by one force.
