Title:
OXIDE SUPERCONDUCTIVE CURRENT LEAD
Document Type and Number:
Japanese Patent JP2009230912
Kind Code:
A
Abstract:

To provide a single current lead with low thermal conductivity and compactness which can supply power to a superconductive equipment.

An oxide superconductive current lead 20 is formed by winding ReBaxCu3Oy system oxide superconductive wire rods A and B of tape shape having a superconductive layer and a stabilizing layer laminated through an intermediate layer on a substrate on the outer circumference of a current lead support 10 through an insulating tape with the substrate face outside so that they may be non-inductive wound in same direction, and by connecting by solder the both terminals of the superconductive wire rod A to a semicircular plate portion of the current terminals 11a, 11b, and by connecting by solder the both terminals of the superconductive wire rod B to a semicircular plate portion of the current terminals 11c, 11d. Thereby, electric power can be supplied by a single current lead and the thermal conductivity amount can be reduced with compactness, and deterioration of superconductive characteristics due to self-magnetic field can be suppressed.
