摘要： PROBLEM TO BE SOLVED: To provide a superconducting coil improved to maintain a predetermined insulation performance by preventing deterioration of a dielectric strength due to air bubbles even during energizing an excessive current by restraining the air bubbles on an outer peripheral side of the superconducting coil as much as possible while securing high heat removal and cooling performances by liquid nitrogen.SOLUTION: In a superconducting coil immersed and cooled in liquid nitrogen, a spiral coil groove 4a is formed on an outer periphery of a cylindrical reel 4, and a tape-like high temperature superconducting wire 5 is wound in the groove. Cooling ducts 4b crossing with the coil groove 4a and extending in a vertical axis direction of the reel 4 are dispersed on a periphery of the reel 4 on an outside diameter side of the reel 4, and an insulation tape 15 impregnated with resin is wound to tightly cover an entire outer periphery of the reel 4 including the superconducting wire 5. Heat generated by the superconducting wire 5 is removed and cooled by the liquid nitrogen circulating in the cooling ducts 4b, so as to restrain air bubbles on the outer periphery side covered with the insulation tape 15 and maintain a predetermined insulation performance.

摘要： PROBLEM TO BE SOLVED: To improve a superconducting coil and a superconducting transformer which are cooled by being immersed in liquid nitrogen so as to retain predetermined insulation properties by suppressing bubble generation of the liquid nitrogen as much as possible when a superconducting wire rod is shifted from a superconduction state to a normal conduction state due to excessive current conduction.SOLUTION: In a vertical type superconducting coil which has a configuration where a tape-like high temperature superconducting wire rod 5 is wound around an outer peripheral surface of a cylindrical spool 4 and is cooled by being immersed in liquid nitrogen used as a coolant, a tape surface on a coil inner diameter side of the superconducting wire rod 5 is overlapped and wound around a peripheral surface of the spool 4 and an insulation tape 14 is wound so as to cover the tape surface of the superconducting wire rod 5 from the outside on a coil outer diameter side to perform such isolation that the tape surface of the superconducting wire rod 5 is not brought into direct contact with the coolant. Bubble generation in the liquid nitrogen due to excessive current conduction is suppressed as much as possible to prevent deterioration of insulation properties of the superconducting coil.
