SUPERCONDUCTING DEVICE FOR MAGNETIC LEVITATION TRAIN

摘要

PURPOSE:To acquire a superconducting device for a magnetic levitation train having good reliability and simple structure by constituting it of a superconducting coil which is hard to generate an eddy current caused by variable magnetic field from an outside and hard to be quenched. CONSTITUTION:A plurality of high temperature superconducting coils 30 provided inside a vacuum container 10 are cooled at a temperature of a liquid helium temperature or higher and half a critical temperature of a high temperature superconducting coil or lower and a conductive cooling device 50 consisting of a metallic member is provided on a surface of the high temperature superconducting coil 30. The metallic member is cut at a position far from a refrigerator 40 not to generate an eddy current.
