TERMINAL STRUCTURE OF SUPERCONDUCTIVE CABLE AND SUPER CONDUCTIVE CABLE LINE

摘要

PROBLEM TO BE SOLVED: To provide a small-sized terminal structure of a superconductive cable that can further reduce a Joule loss and heat intrusion, and the superconductive cable conduit equipped with the terminal structure.

SOLUTION: The small-sized terminal structure comprises: a conductor 20 electrically connected to the end of the superconductive cable 100 (cable core 102); a bushing 21 containing the conductor 20; and a low-temperature tank 22 into which the connection side of the cable of the conductor 10 is accommodated. The terminal structure further comprises a power changer 25 that changes the magnitude of a voltage applied to the superconductive cable 100 or a voltage applied to the conductor 20 between the end of a lead 114 and the conductor 20.
