摘要：

Current lead is an important part of the superconducting cable termination. When a short circuit fault occurs, a large amount of heat generated in a short period of time will affect the temperature distribution of current leads. In this paper, a temperature field simulation model of current leads is built on the basis of theoretical calculation. Based on the optimized parameters of the HTS cable, the influence of magnitude and time of short circuit current on the temperature distribution of the current lead is studied, and the effect of the short circuit fault on temperature rise in different positions is also analyzed. The obtained results show that the magnitude and time of short circuit current have great effects on temperature distribution of current lead. Effect of short circuit current on the temperature distribution at the hot end is larger than that at the cold end.
