摘要

第二代高温超导带材制备的超导磁体可以工作在15~77 K热力学温度下，相比于工作在4.2 K温度以下（液氦温区）的低温超导磁体，制冷成本更低，可以摆脱我国对液氦稀缺资源的依赖。文章对标山梨磁浮测试线车载低温磁体的公开数据，进行了高温超导磁体总体结构的初步设计，并基于有限元仿真，对磁体的电磁、力学传递结构和漏热情况进行分析，得到一种适用于全尺寸高速电动磁浮的车载高温超导磁体的综合设计方案。

Abstract

The superconducting magnet based on the second-generation high-temperature superconducting (HTS) tape can work at 15 K to 77 K. Compared with the low-temperature superconducting (LTS) magnet working below 4.2 K (the liquid helium temperature zone), the refrigeration cost of HTS magnets is lower, which can get rid of the scarce resources of liquid helium in China.In this paper, the primary design of the overall structure of high temperature superconducting magnet was carried out based on the open data of the vehicle mounted low temperature magnet of the standard Yamanashi maglev test line. Based on the finite element simulation, the electromagnetic and mechanical transfer structure and heat leakage of the magnet were analyzed, and a comprehensive design scheme of the vehicle mounted high temperature superconducting magnet suitable for full-scale and high-speed electric maglev was obtained.
