Beschreibung
Zusammenfassung:	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 close
