| 摘 要： | 电流引线是连接超导低温装置室温电源与超导单元的桥梁,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,提出了气冷变截面电流引线优化设计方法.应用此方法为一个YBCO高温超导带材临界电流特性测试装置设计了变截面电流引线.通过对电流引线的温度场分布进行实验测量,并与设计值进行比较,结果吻合较好,证明了气冷变截面电流引线设计方法的有效性和实际优化效果.本文的设计方法及相关实验研究为变截面电流引线在超导低温装置中的实际应用提供了一定的参考.

| Abstract: | 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 segment 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 loss.Finally the experimental m... |
