Abstract

The heater-triggered switching system for charging of a high temperature superconductor(HTS) is prepared by simulation and investigated its characteristic by experiment. heater-triggered switching system consists of two nickel-chrome alloy heater, an electromagnet and YBCO bulk HTS. There are three important parameters to generate the pumping-current in this system. The timing sequential control of two heters and electromagnet is an important factor to generate pumping-current in the YBCO bulk HTS. Thermal analysis of the switching part in YBCO bulk HTS according to the heater input current was carried out. Electromagnet of 0.6[T] and DC heater input current of 2.3[A] were optimally derived. In this experiment, the maximum pumping current is reaches about 12[A].
