摘　　要：电流引线是连接室温端电源和低温端超导装置的重要部件,也是超导装置热损耗的主要热源之一。选择合适的电流引线形式,并进行引线结构优化设计,可以提高超导装置的可靠性和经济性。概述了电流引线的优化设计目标和分类形式,介绍了全金属电流引线、高温超导电流引线和珀尔帖电流引线的研究进展,分析比较了三类电流引线的工作特点和适用场景,可为超导装置的电流引线选型和优化设计提供参考。Current lead is an important component connecting the power supply at room temperature and the superconducting device at low temperature, as well as one of the main heat sources of heat loss in superconducting devices. The reliability and economy of superconducting devices can be improved by selecting appropriate current leads and optimizing the lead structure. In this paper, the optimal design objectives and classification forms of current leads were summarized, and the research progress of all-metal current leads, high temperature superconducting current leads and Peltier current leads were introduced. The working characteristics and applicable scenarios of the three types of current leads were analyzed and compared, which can provide reference for the selection and optimal design of current leads in superconducting devices.
