CURRENT LEAD OF SUPERCONDUCTIVE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a simple means which is capable of restraining heat from penetrating into the cooling system of a superconductive apparatus as much as possible so as to enable a superconductive apparatus product-related industry to promote the production of energy-saving products more. SOLUTION: Superconductive apparatus current leads are, at least, partially formed of high-temperature superconductor of low thermal conductivity and equipped with, as shown in Figure 1, 'a current lead cooling control means' such as a current lead-dedicated refrigerator 7 or the like which forcibly cools down the above high-temperature superconductor 6 below its superconductive transition temperature when a current is applied to it or releases at least the high-temperature end side (power supply side) of the high-temperature superconductor 6 from forced cooling when a current is stopped.
