An electric power feed structure for a superconducting apparatus, which is used to input or output electric power between the cryogenic-temperature side and the room-temperature side, comprises a coolant vessel containing a superconducting section provided in the superconducting apparatus, a vacuum thermal insulation vessel arranged to surround the outer periphery of the coolant vessel, and a feed conductor part having one end arranged in the room temperature side and having the other end connected to the superconducting section. The feed conductor part is divided into a cryogenic-temperature side conductor connected to the superconducting section and a room-temperature side conductor arranged in the room temperature side such that the cryogenic-temperature side conductor and the room-temperature side conductor can be detachably attached to each other. Thus, provided are the electric power feed structure for a superconducting apparatus and a superconducting cable line equipped with the electric power feed structure in which the electric power fed between the cryogenic-temperature side and the room-temperature side can be easily varied by changing an effective conductor cross-sectional area. |
