High temperature superconductor arrangement has superconductor with weak points with reduced critical current density distributed along current flow direction

The arrangement has a superconductor (1) with weak points (A,B) distributed along the current flow direction (I) with reduced critical current density compared to the rest of the superconductor. At least one weak point has a reduced cross-section of a current-carrying cross-section of the superconductor. Independent claims are also included for the following: the use of a high temperature superconductor in a superconducting current limiter.

Die vorliegende Erfindung hat eine Hochtemperatursupraleiteranordnung zum Gegenstand, welche insbesondere zur Verwendung in Strombegrenzern geeignet ist. Über die gesamte Länge des Supraleiters (1) verteilte Schwachstellen (A, B) agieren als potentielle Hot-Spots und ermöglichen im Fehlerfall ein homogenes Quenchen des Supraleiters. Die Schwachstellen sind durch eine reduzierte kritische Stromdichte oder eine Verringerung des Leiterquerschnitts charakterisiert.
