摘　　要：主要研究68 kA高温超导电流引线的关键参数,首先,对盒式超导接头直流电阻、换热器优化和整体安全分析的方法进行研究,随后对引线进行低温性能实验,结果表明,接头直流电阻、换热器流量消耗、LOFA及Burnout时间等关键参数的计算结果与实验结果基本相符,本研究验证了关键参数计算及分析方法的准确性。Key parameters of 68 kA high temperature superconducting(HTS)current lead were mainly studied.Firstly,the DC resistance calculation of the superconducting joint box was carried out,the optimization analysis of the heat exchanger and the safety analysis of HTS current lead were done.Moreover,the low-temperature experimental tests were then conducted for further verification.It indicates that the calculated key parameters such as the DC resistance of the superconducting joint box,flow consumption of heat exchanger,the LOFA time(the safety working time under the loss of flow accident)and Burnout time are in good agreement with the experimental results.This study verifies the accuracy of the calculation and analysis method of key parameters.
