摘　　要：超导低温装置中的电流引线连接室温中的电源与超导单元,其漏热直接关系到低温系统的运行稳定与运行成本.本文对传统的气冷电流引线分段计算方法做了一定的改进,形成了气冷变截面电流引线优化设计方法.使用此方法为一个YBCOHTS带材临界电流测试装置设计了变截面电流引线.本文的设计方法为变截面电流引线的实际应用提供了一定的参考.The heat leakage of the current leads which connect the power and superconducting equipment is very important for the stable and economical operation of critical superconducting devices. Improved seg- ment algorithm is used to obtain the optimal length and cross-section of a gas cooled current lead with varying cross-section. Based on the improved method, we have designed a current lead with varying cross- section for critical current test of HTS YBCO tape with less conductive heat toss. The optimal design results contribute to the utility of HTS current lead.
