SUPER-CONDUCTIVE MAGNET FOR MAGNETIC LEVITATION RAIL VEHICLE |
摘要 |
PROBLEM TO BE SOLVED: To provide a lightweight, reliable super-conductive magnet for a magnetic levitation rail vehicle. SOLUTION: The super-conductive magnet for a magnetic levitation rail vehicle includes a superconducting coil 5 made of rare earth element-based high-temperature superconductor and a radiation heat shield plate 2 for preventing increase of temperatures. Only at the first time, the superconducting coil 5 is cooled actively, and after that, the superconducting coil 5 is cooled indirectly by the large heat capacity of the superconducting coil 5 and cooling of the radiation heat shield plate 2 so that it may not become more than a temperature causing the superconducting coil 5 to be in super-conductive state.
