摘要
高温超导电流引线作为减少漏热的有效途径,在超导磁体系统中得到了广泛的应用。本文介绍了大型超导磁体用高温超导电流引线的结构和材料。此外,还描述了高温超导电流引线的热特性。为了研究高温超导电流引线在正常运行和故障运行条件下绝缘结构对其电强度的影响,采用有限元法对16 kV高温超导电流引线进行了电分析。仿真结果表明,高温超导电流引线具有足够的介电强度。
As an effective way to reduce the heat leakage,High Temperature Superconducting(HTS)current leads were widely used in the superconducting magnets system.In this paper,the structure and materials of HTS current leads for large scale superconducting magnets were presented.Furthermore,the thermal characteristics of HTS current leads were described.To reveal the influence of insulating structure on the electrical strength of HTS current lead under normal operating condition and fault operating condition,the electrical analysis of a 16 kV HTS current lead were performed based on finite element technology.The simulating results indicate the dielectric strength of the HTS current lead is enough.
