摘要
介绍一种电磁悬浮式高温超导磁悬浮技术。它的基本结构是,铁质参照系在悬浮装置的上面,高温超导磁悬浮装置悬挂在铁质参照系的下面,用悬浮装置上高温超导绕组磁体或高温超导永磁体实现磁悬浮。与其他悬磁浮技术比较,有以下优点:沿地面轨道无磁场,能静止悬浮,悬浮高度较高(30- 100m m )。悬浮装置上的磁场较低(0.5- 2.0T),且因磁路闭合,环境磁场很低。工作在液氮温度(77K),制造和运行成本较低。该技术适用于所有需要磁悬浮的地方。文中提出了几种可能实现的薄壁液氮低温容器方案。
A high temperature superconducting electromagnetic levitation is described. The essential frame of the scheme of the electromagnetic levitation (EML) Maglev using high T c superconducting permanent magnets and high T c superconducting magnet wind are discussed. This high temperature superconducting EML technology is suitable for all places using Maglev. In the paper, several feasible liquid nitrogen vessels with thin wall used in the EML Maglev are presented, and the configuration scheme diagram is also given.
