PURPOSE:To prevent quenching due to the slip of a superconducting wire rod, and to obtain a superconducting coil having high reliability by installing an elastic deforming member between the superconducting coil and the bobbin on which the superconducting coil is wound, and applying tension to the superconducting coil at all times. CONSTITUTION:Bisected semicylindrical members 3 are mounted on the outer circumference of a bobbin 2 by belleville springs 4. When a superconducting coil wire rod is wound on the outer circumferences of the semicylindrical members 3 mounted, the belleville springs 4 are compressed and deformed because the semicylindrical members 3 are pushed. When the superconducting wire rod is moved expansively in the outward direction by an electromagnetic force, the semicylindrical members 3 are expanded to the outside by the restoring force of the belleville springs 4 applied at all times from the inside to the outside, thus checking the movement of the superconducting wire rod. |
