Abstract

The temperature characteristics of the persistent current switch (PCS) were analyzed by using the heat transfer equations. The optimal conditions for the design of the PCS were derived in this paper. The maximum operating current in a persistent mode was 100A(at 1.5T). The PCS was opened after several tens msec by heater currents. The heater current which could minimize thermal losses was 150mA. The experimental results of the designed PCS agreed well with the calculated results.
