The invention discloses a medium-low-speed magnetic levitation vehicle and a superconducting electromagnet for medium-low-speed magnetic levitation. The medium-low speed magnetic levitation vehicle comprises an electromagnet assembly, an inner polar plate and an outer polar plate, the electromagnet assembly is arranged between the inner polar plate and the outer polar plate, and the electromagnetassembly comprises a Dewar outer barrel and a Dewar inner barrel which are sleeved to form a closed cavity for containing liquid nitrogen; a hollow through hole for mounting an iron core is formed inthe Dewar inner barrel; and a superconducting coil is arranged on the inner wall, which is positioned in the closed cavity, of the Dewar inner cylinder. According to the superconducting electromagnetfor medium-low-speed magnetic levitation, the Dewar outer barrel and the Dewar inner barrel form the closed cavity, and the closed cavity contains the liquid nitrogen; and the hollow through hole forinstalling the iron core is formed in the Dewar inner barrel, and the superconducting coil is arranged on the inner wall, which is positioned in the closed cavity, of the Dewar inner cylinder. Compared with the prior art, the superconducting coil is large in current-carrying capacity, the number of turns and the weight of the coil are reduced, loss heating does not exist in the superconducting coil, a whole vehicle suspension capacity is prevented from being affected by coil temperature rise, and the whole vehicle efficiency is improved.

    本发明公开了一种中低速磁悬浮车辆及中低速磁悬浮用超导电磁铁,包括电磁铁组件、内极板和外极板,电磁铁组件设于内极板和外极板间,电磁铁组件包括:套装以形成承装液氮的密闭腔体的杜瓦外筒和杜瓦内筒,杜瓦内筒形成用以安装铁芯的中空通孔;杜瓦内筒处于密闭腔体的内壁上套设有超导线圈。应用本发明提供的中低速磁悬浮用超导电磁铁,杜瓦外筒和杜瓦内筒形成密闭腔体,密闭腔体承装液氮;杜瓦内筒形成安装铁芯的中空通孔,杜瓦内筒处于密闭腔体的内壁上套设超导线圈。相较于现有技术,超导线圈载流能力大,降低线圈匝数及重量,且超导线圈不存在损耗发热,避免线圈温升高影响整车悬浮能力,提高整车效率。
