초전도 자기부상열차용 극저온 축열체 냉각 시스템의 열적 특성

초록

Superconducting Maglev trains are attracting attention in future high-speed train research as they are characterized high current density by superconductors. Cryogenic cooling is required as a critical conditions of superconductivity, and weight, space, and power supply problems occur when a cooling system is mounted on a Maglev train. To overcome this problem, the research on the cryogenic thermal battery for a detachable cooling system are conducted. In this study, a solid nitrogen thermal battery cooling system was designed two-pole superconducting module with magneto-motive force of 150 kA-turn. Subsequently, experimental verification was performed on a driving scenario of superconducting Maglev train, including initial cooling of the mover through the cryogenic cooling system of the station, separation of the cooling system and driving of the mover.
