Abstract
Disclosed is an insulation treatment method for a helium inlet pipe of a superconducting magnet. The superconducting magnet has a structure with varying T-shaped cross section. The irregular parts of the magnet are filled with G10 to reduce the difficulty in the insulation treatment caused by the irregular shape. Moreover, a skirt-shaped insulating material is provided around the metal conduit to overcome the reduction in the insulation electrical performance caused by the defects in the insulation treatment for such irregular parts. The application designs a sample structure for insulation treatment, and can wrap the superconducting magnet having the T-shaped varying cross-section with insulating materials before vacuum pressure impregnation, meeting special requirements of high-voltage insulation treatment for the superconducting magnet with a complex structure under low temperature and vacuum environment.
