Title:
超電導テープ線、超電導テープを用いた超電導電流リード、永久電流スイッチおよび超電導コイル
Document Type and Number:
Japanese Patent JP6678509
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a superconductive tape wire in which a protective layer is not eliminated at the time of soldering work by combining two types of high temperature superconductive tape wires constituted by using a high strength material as a metal substrate and constituting the superconductive tape wire, and further to provide a superconductive current lead which is constituted by using the superconductive tape wire and improves safety, a permanent current switch, and a superconducting coil.SOLUTION: A second high temperature superconductive tape wire 2 is connected to an intermediate layer constituting a first high temperature superconductive tape wire 1 by using first solder 4a having a low melting point, and a metal electrode 3 for supplying an external current is connected to a stabilizing layer being further formed on the intermediate layer constituting a second high temperature superconductive tape wire 2 by using second solder 4b having a low melting point having a melting point temperature higher than that of the first solder 4a. By these connection, at the time of soldering work, the protective layer is not eliminated, and connection strength to the metal electrode 3 can be enhanced.SELECTED DRAWING: Figure 1
