Abstract
For obtaining a compact superconductive power switch for rapid switching speeds and with high dielectric strength, several winding layers ( ) with several windings each are lined up adjacent each other in axial direction. Between individual layers ( ), there are provided cooling/heating elements ( to ) in order to transfer the high-current switch unit ( ) to the superconducting state and the normally conducting state, respectively, by cooling/heating, i.e. for closing and opening said unit, respectively. Mutually adjacent current conductors have the switching current flowing therethrough in opposite directions, so that the high-current switch unit ( ) is of low induction, which permits fast switching times in particular when the switch is opened by an additional current pulse. Due to the numerous windings of the current conductor sections in each layer and the plurality of layers in axial directions, only a low voltage differential results between the adjacent current conductors, and an assembly with high dielectric strength is obtained in total.
