摘 要: 基于高温超导磁悬浮技术的非接触式密封输运系统,具有载重能力高、悬浮间距大等特点,非常适合特殊物质悬浮密封运输应用。常规的高温超导磁悬浮系统在液氮温区的悬浮效率尚未充分发挥,因此,本文提出了采用预磁化磁体提升密封输运系统悬浮间距的方法,并进行了相关实验测试及理论分析。通过高温超导块材内部电流构型分析,以及磁化后高温超导块材悬浮特性的变化趋势对比,揭示了采用磁化高温超导块材提升悬浮系统性能的可行性与有效性。本文相关实验数据、分析及结论可为高温超导磁浮密封输运系统工程应用提供参考。

Abstract: The contact-less sealed transportation system based on high temperature superconductive (HTS) maglev system has the advantages in large levitation force and levitation gap, which is very suitable for the contact-less sealed transportation of special materials. Because the working efficiency of HTS maglev is not very high at liquid nitrogen temperature zone, this paper purposes a method to improve the levitation gap of HTS maglev system, based on pre-magnetized bulk high temperature superconductor, with experiments and theory analyses. The effectiveness of magnetized bulks high temperature superconductor (HTSC) to improve the levitation performance of HTS maglev system is proved by the analyses of supercurrents configuration within the magnetized bulk HTSC and the comparison of levitation variation trend of magnetized bulk HTSC.The tested data, analysis and conclusions in this paper can supply useful references for the engineering application of HTS maglev sealed transportation system.
