摘要： PROBLEM TO BE SOLVED: To provide an intermediate connection structure of a superconducting cable which is excellent in workability in connection and is capable of reducing loss due to energization. SOLUTION: The intermediate connection structure 1A connects a pair of superconducting cables equipped with an electric insulating layer 203, a superconducting shielding layer 204, and a normal conducting layer 205 sequentially formed on the outer circumference of a superconductor 202. The intermediate connection structure 1A includes a superconducting connection portion 20 made of a superconducting wire material and connecting the superconducting shielding layers 204, a copper-made supporting member 21A connected to the superconducting connection portion 20 but not connected to the normal conducting layer 205, and a normal conducting connection portion 3 made of copper and connecting the normal conducting layers 205. Since the connection member of the superconducting shielding layers 204 and the connection member of the normal conducting layers 205 are provided separately, connection work can be readily executed. Since the superconducting connection portion 20 is provided on the inner circumferential side of the supporting member 21A, even if a large current is applied, a branch flow hardly occurs on the supporting member 21A made of copper.

摘要： PROBLEM TO BE SOLVED: To provide a method for measuring a critical current in a super conductive cable, the method being capable of measuring a critical current in a superconductive cable with high accuracy using a small capacity electric power source.SOLUTION: In a superconductive cable 1A in which cable cores 10a, 10b, and 10c having superconductive conductor layers 11 and superconductive shield layers 12 are housed in a heat insulating tube 13 A, ends of two cores, 10a and 10 b, are electrically connected with a lead member 2 and a DC power supply 3 is connected to the other ends so that current passes through both cores 10a and 10b reciprocally. A critical current is measured by providing a direct current to the superconductive conductor layers 11 at a fixed change speed. Then is calculated the reduction amount of the critical current decreased by a leakage magnetic field based on the difference between a current applied to the superconductive conductor layer 11 fixed to the core 10a and an induction current passing through the superconductive shield layer 12 fixed to the core 10a. A critical current can be accurately measured by correcting the reduction amount due to the leakage magnetic field for a measured critical current even when a small capacity electric power source is used.
