Inductive current limiter when using ceramic high temperature superconductors; Induktiver Strombegrenzer unter Verwendung von keramischen Hochtemperatur Supraleitern

Abstract

As an inherently safe component, the current limiter in high temperature superconductors is intended to prevent and limit damage in the case of short circuits in electrical networks. It achieves both an increase in the safety of the installations and thus ensures the availability of the energy supply, as well as reducing costs, as switches and installations no longer need to be dimensioned for loads caused by short circuits. In addition to this, current limiters represent an early implementation of the high temperature superconductor which can be applied in energy technology and thus act as a valuable pacesetter for further applications of these materials. During the period covered by the reports a limiter of average output (20 kVA) was built and tested as an important development step. Producing the switch winding in superconductive rings with 20 cm diameter and 100 A current carrying capacity respectively has led to the largest application of high temperature superconductors to-date. The dynamic tests have, however, revealed an unexpected problem, namely the formation of hot spots during the switching process. Structural measures to solve this are currently undergoing tests. It is planned, to start immediately after completion of this work to build a prototype with  More>>
