MANUFACTURE OF SUPERCONDUCTING MAGNET AND IMPREGNATING APPARATUS FOR SUPERCONDUCTING MAGNET WITH IMPREGNANT

摘要

PURPOSE: To restrain the movement of a superconducting conductor for wirings by a method wherein a turning effort is exerted on a superconducting coil around a bobbin and the superconducting coil is impregnated with an impregnant while it is being turned. ;CONSTITUTION: A vacuum container 41 and a resin container 51 are evacuated by using a vacuum pump 42; the air and air bobbies of a resin 44 inside the resin container 51 are removed; air between windings for a superconducting magnet 45 is evacuated. In succession, a motor 4 is turned. In a state that an impregnation container 43b and the superconducting magnet 45 are being turned, the air between the windings is evacuated additionally. In a state that the superconducting magnet 45 has been set to a stationary rotation, a valve 52 is opened and the resin 44 is fed to the superconducting magnet 45. When the magnet has been impregnated with the resin 44, the vacuum pump 42 is stopped, a valve 54 is opened and compressed air is fed to the vacuum container 42. While the inside of the vacuum container 41 is kept at a definite pressure, the resin 44 between the windings is heated and hardened. Thereby, the windings can be impregnated with the impregnant up to every corner.;COPYRIGHT: (C)1993,JPO&Japio
