ABSTRACT:
An oxide superconductor current lead in which generation of Joule heat at joint portions with a system side conductor and a power supply side conductor is reduced with use of an oxide superconductor with less heat penetration into a super conducting equipment system is provided. A columnar oxide superconductor molten bodies (interelectrode superconductor260, in-electrode superconductors280aand280b) are produced, the in-electrode superconductor280aand a left end portion of the interelectrode superconductor260are placed into a power supply side metallic electrode210, and the in-electrode superconductor280band a right end portion of the interelectrode superconductor260are similarly placed in a system side metallic electrode211, then degassed joining metal is used to join them to form an oxide superconductor current lead201, a power supply side conductor5from a power supply is joined to the power supply side metallic electrode210, and a system side conductor202from a superconducting system side is joined to the system side metallic electrode211with use of respective clamps203aand203b.
