Abstract (en)

[origin: WO9852236A1] In order to obtain a voltage-stable compact superconducting power switch with high operating speed, several layers (10a...10h) of windings with several windings in each layer are arranged next to each other in an axial direction. Cooling and heating elements (8a-8d) are arranged in between the individual layers (10a...10h) so that the heavy-current disconnector unit (1) can be switched into a superconducting or normal conducting mode, i.e. closed or opened, by means of cooling/heating. Each adjacent conductor is cross-flown in an opposite direction by the heavy current so that the heavy current disconnector unit (1) exhibits low induction, thereby enabling especially high operating speeds when the disconnector is opened by an additional current pulse. The many windings of the conductor segment in each layer and the several layers in an axial direction result in a low current differential between the adjacent conductors. A high voltage-stable component is thus obtained.
