Abstract
PURPOSE:To decrease heat loss when a current is not conducted and is conducted, by forming the low temperature side of a current lead, whose temperature is lower than a liquid nitrogen temperature, of a superconductive part, which is composed of an oxide superconductive member. CONSTITUTION:An oxide superconductive material 32, which has a critical superconductive temperature higher than a liquid nitrogen temperature, is used as a member of a superconductive part 22 on the low temperature side of a current lead. Namely, the oxide superconductor 32 is used for the superconductive part 22 on the low temperature side of the current lead for superconducting equipment. Therefore, Joule's heat is not yielded when a current is conducted. It is not required to cool the superconductive part 22 when the current is conducted. The superconductor is kept at the level of the liquid nitrogen temperature at the time when the current is not conducted. Special cooling is not required when the current is conducted. Therefore, the amount of heat loss is the same when the current is conducted or is not conducted, and the amount can be further decreased.
