Zusammenfassung

Die Begrenzung von Kurzschlussströmen mittels supraleitenden Strombegrenzern ist Gegenstand intensiver internationaler langjähriger Forschungstätigkeit. Supraleitende Strombegrenzer nutzen den Übergang des Supraleiters vom supraleitenden in den normalleitenden Zustand und funktionieren somit wie ein nichtlinearer Widerstand. Durch diese intrinsischen physikalischen Eigenschaften kommt der supraleitende Strombegrenzer dem Idealbild eines Begrenzers, spannungsabfalloser Normalbetrieb und ultraschnelle Begrenzung im Kurzschlussfall, nahe.

Abstract

Limiting fault currents by means of superconducting current limiters has been topic of intensive international research for many years. Superconducting current limiters make use of the super-conducter’s transition from superconducting to normal conducting state, and therefore it works like a nonlinear resistance. Due to its intrinsic physical proterties the superconducting current limiter comes close to an ideal limiter.
