PURPOSE:To form a superconductive coil device in a coil construction having small friction, and to hold stably the superconductive condition thereof by a method wherein the coil is wound in an edgewise solenoid winding, insulating sheets are arranged between the respective layers, and side plate bodies are fixed to a cylindrical body as to apply pressure to the axial direction of a bobbin. CONSTITUTION:A superconductive coil 20 is wound in an edgewise solenoid winding for the plural number of layers around a spool 10, and insulating sheets 40 are wound between the respective layers of the coil 20. Moreover, a second side plate body 13 is fixed to a cylindrical body 11 as to apply pressure in the winding axial direction of the coil 20 at a point in time when winding of the whole layers of the superconductive coil 20 is completed. Accordingly, friction of the superconductive coil in the winding axial direction can be lightened remarkably, and because the superconductive conductors move being unified in one body in regard to electromagnetic force in the diametrical direction being disabled to move independently one piece by one piece, friction to the direction thereof can be lightened sufficiently. Therefore, the superconductive condition can be held stably. |
