摘　　要：超导核聚变实验装置(EAST)的极向场超导磁体常常运行在空载、变电流条件下;;将这种电流引线设计成过载电流引线可以进一步降低低温系统的热负荷。本文计算了不同材料制作的电流引线在额定电流和过载情况下的漏热、温度分布等参数;;在分析计算的基础上给出了制造电流引线时的选材原则以及过载运行的条件。Superconducting magnets of EAST(Experimental advanced superconducting tokamak)’s poloidal field have usually worked in zero load and variable load. It is economical that the current leads are designed as an overload lead. Some important parameters of poloidal field, such as heat load and temperature distribution, are calculated for current leads made of deferent materials at rated current and overload current in this paper. The principle of selecting material for manufacturing current lead is given. At the same time, the condition that the current lead can work at overload current is discussed.
