摘　　要：基于传热学理论,设计制作了12T高温超导导体测试装置的电流引线,它主要由铜换热器和高温超导段组成,铜换热器设计成换热面积大的叠片式结构,高温超导段采用Bi-2223/Ag-Au和YBCO超导材料共同实现载流。利用有限元分析软件对高温超导段冷端热负荷及载流能力进行了分析,比较了全Bi系材料、Bi系和Y系材料混合来制作高温超导段的载流效果。结果表明,采用Bi系和Y系材料共同载流的效果较好,该电流引线可满足测试装置载流能力大于12kA、20K冷端漏热小于4W的运行需求。According to the heat transfer theory,the current leads for 12T high-temperature superconducting(HTS)conductor test facility are designed and manufactured,which are mainly composed of copper heat exchanger and HTS module.The copper heat exchanger is designed as a stacked structure with large heat exchange area.Bi-2223/Ag-Au and YBCO superconducting materials are used for current-carrying in the HTS module.The thermal load and current-carrying capacity of the HTS module are analyzed by the finite element analysis software.The current-carrying capacity of the HTS module made by Bi tapes alone and its combination with Y tapes is compared.The results show that the combination of Bi and Y tapes have a better capacity on current carrying,and the leads meet the operation requirements of the test facility with current-carrying capacity greater than 12kA and the heat leakage less than 4W at 20K.
