Abstract

In order to increase current capacity of a mechanical persistent current switch (PCS) which realizes zero contact resistance, parallel connection is suitable for no reduction in the total OFF resistance due to infinite OFF resistance of each PCS. In this study, a mechanism of the sequential quench in the parallel circuit of two mechanical PCS's was clarified by numerical analysis of changes in the currents before and after the quench as well as by considering the quench time lag property investigated with the pulsed current. Additionally, it was discussed whether a quenched PCS in the parallel circuit could recover its superconducting state by making it open and then close again.
