ABSTRACT:
A cooling device for current lines of a superconducting rotating machine, which is capable of removing heat generated from the current lines of the superconducting rotating machine, thereby effectively preventing a superconducting coil from being deformed due to the heat generated from the current lines, is disclosed. The cooling device includes heat conduction members respectively mounted to outer surfaces of the current lines. Each heat conduction member is in contact with an inner peripheral surface of the stator such that the heat conduction member transfers, to the stator, heat generated from a corresponding one of the current lines. The heat conduction member further includes insulators each surrounding a corresponding one of the current lines between a corresponding one of the heat conduction members and a power slip ring arranged in the stator, to thermally insulate the heat generated from the corresponding current line.
