According to the high-temperature superconducting magnet rapid off-line device and the high-temperature superconducting electric magnetic levitation vehicle, the cut-off deflation device is additionally arranged between the cold head of the high-temperature superconducting magnet and the refrigerating machine, and under the normal condition, the hard pipeline, the first self-sealing connector, the cut-off valve and the second self-sealing connector are in the conducting state; refrigerating gas circulation between the refrigerating machine and the cold head is achieved. When a high-temperature superconducting magnet line test needs to be carried out, the stop valve is firstly closed to ensure that the pressure of the refrigeration gas in the pipeline between the stop valve and the refrigerator is unchanged, then the vent valve is opened to reduce the pressure of the refrigeration gas in the pipeline between the stop valve and the cold head to be within a preset pressure range, and then the vent valve is closed; and then the male head and the female head of the first self-sealing joint are disconnected. By means of the arrangement, the self-sealing connector does not need to be dismantled before pressure reduction, but is disconnected after pressure reduction, so that the operation time for disconnecting a refrigeration pipeline is shortened, and the service life of the self-sealing connector can be greatly prolonged.

    本发明提供的一种高温超导磁体快速脱机装置及高温超导电动磁浮车辆,在高温超导磁体的冷头和制冷机之间增设截止放气装置,正常情况下,硬管路、第一自密封接头、截止阀和第二自密封接头呈导通状态,实现制冷机和冷头之间的制冷气体循环。当需要进行高温超导磁体线路试验时,首先关闭截止阀,保证截止阀到制冷机之间管路内制冷气体的压力不变,然后打开放气阀,将截止阀到冷头之间管路内制冷气体的压力减小到预设压力范围内,再关闭放气阀,随后断开第一自密封接头的公头和母头之间的连接。上述设置,可以实现自密封接头在减压前无需拆除、而是待降低压力后再断开连接,从而缩短了断开制冷管路的操作时间,可极大提高自密封接头的使用寿命。
