高温超导限流器是一种新型的故障短路电流限制装置,具有良好的应用前景,其中电流引线漏热是高温超导限流器的主要漏热源之一,它的漏热量直接影响了高温超导限流器的总体性能,因此,引线的设计与优化一直备受关注。本文设计了用于400V/200A高温超导限流器的电流引线,采用Ansys软件计算了其温度场分布,并对引线进行了优化分析,分析计算结果能为后续高温超导限流器的设计提供技术支持。

The High Temperature Superconducting Fault Current Limiter （HTSFCL） is a new type of fault current limiter with wide application. The current lead of HTFSCL is a part that leads to leak out heat, and its thermal leakage loss greatly influents the performance of cryogenic system. So it is importance to design and optimize the current lead. This paper introduces the design methods of the current lead of 400 V/200 A HTSFCL. Depended on the calculated conclusion of temperature field with Ansys soft, the optimization of the design of current lead is carried out. The result can provide technological support for the future work.
