PROBLEM TO BE SOLVED: To provide a current lead which simultaneously uniformly cools three or more conductors connected to a plurality of superconductive coils irrespective of the presence or absence of an energization, and which can further reduce the installing space of the current lead. SOLUTION: A cooling gas 6 flows from a cutout 5 of a refrigerant tank side of a plurality of stages of insulating plates 4 formed in a cylindrical member 3 into the cylindrical member 3. The cooling gas 6 flowing into the cylindrical member 3 passes through the cutouts 5 of each insulating plate 4 while the conductors 2 are cooled and flows in a zigzag manner from the refrigerant tank side toward a power supply side in the cylindrical member 3. In this current lead 1, the one cylindrical member 3 contains the plurality of the conductors 2 connected to the plurality of the superconductive coils and simultaneously uniformly cools the plurality of the conductors 2 by the cooling gas 6. Further, the installing space of the current lead 1 is reduced. COPYRIGHT: (C)2004,JPO&NCIPI |
