TERMINAL STRUCTURE OF SUPERCONDUCTING CABLE

摘要

PROBLEM TO BE SOLVED: To provide a terminal structure of a superconducting cable capable of alleviating resistance of a connection site of a superconducting thin film of a superconducting conductor layer and normally conducting conductor part.

SOLUTION: The terminal structure is provided with a superconducting conductor layer 113 of the superconducting cable, and a normally conducting conductor part 353 connected with the superconducting conductor layer for exchanging power with an equipment of normal temperature side. The superconducting conductor layer 113 is structured by spirally winding superconducting wire rods 2 having a superconducting thin film 26 formed on the substrate 22 so as the superconducting thin film 26 to be at an inner periphery side and the substrate 22 at an outer periphery side. The terminal structure is provided with a normally conducting connection member 4 having a jointing face 42 adjacent to the superconducting thin film 26, a connecting-use superconducting sheet 5 equipped with a superconducting layer 56 facing the superconducting thin film 26 so as to be astride the jointing face 42, and a conductive jointing material 6 jointing to superconducting layer 56 with both the superconducting thin film 26 and the jointing face 42. The normally conducting connection member 4 is provided with a through-hole 44 for guiding the conductive jointing material 6 to the jointing face 42 from its outer periphery face.
