Document Type and Number:
Japanese Patent JP2603002
Kind Code:
B2
Abstract:
PURPOSE:To get the rotor of a superconductive dynamo-electric machine which is equipped with a current lead capable of preventing the beak of an insulating inner tube by the difference in thermal elongation occurring in said insulating tube, a conductive pipe, etc., in, operation of the rotor, concerning the structure of the current lead which supplies a current to the superconductive coil in the rotor of the superconductive dynamo-electric machine. CONSTITUTION:A normal temperature part conductive terminal 21 and an ultralow temperature part conductive terminal 22 are arranged in opposition. A conductive pipe 23 is arranged between the normal temperature part conductive terminal 21 and the ultralow temperature conductive terminal 22, and connects both conductive terminals 21 and 22 electrically with each other. An insulating inner tube 32 is split by a split part 33. Each of the split insulating inner tube 32 is fixed to the normal temperature part conductive terminal 21 or the ultralow temperature part conductive terminal 22 at a fixing part 25 or 26. The ultralow temperature part conductive terminal 22 is connected to a superconductive field coil 5 through a second lead 31.
