Abstract

The invention discloses a superconducting CICC solenoid magnet coil vacuum pressure impregnation die and an impregnation process. The impregnation die comprises a cylindrical outer die; the outer dieis internally and concentrically provided with an inner die; both the outer die and the inner die are formed by assembly of multiple arc segmented dies; the bottom of the outer die and the inner die is positioned and erected on a bottom die; and the bottom of the bottom die is uniformly provided with a plurality of glue injection nozzles communicated with a coil glue injection and molding cavity along a circumferential direction. The impregnation process comprises the step of heating and degassing the coil in the impregnation die. Starting from the particularity of a conductor material in thesuperconducting CICC solenoid magnet coil, the superconducting coil impregnation die and the process are optimized and designed, and the technical problems of large brittleness, easy breaking and large coil size after a Nb3Sn superconducting wire and an S-glass insulating glass ribbon are wound to a coil and are subjected to thermal treatment can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of vacuum pressure impregnation, in particular to a superconducting CICC solenoid magnet coil vacuum pressure impregnation mold and an impregnation process. Background technique [0002] At present, the superconducting coil impregnation process mostly adopts vacuum pressure impregnation. The basic steps are: put the superconducting coil in a container, then put the container with the coil in the impregnation tank, vacuum the impregnation tank, and then put the epoxy resin Input it into the container in the vacuum impregnation tank, immerse the coil, hold the pressure for a certain period of time, fill the impregnation tank with air or inert gas to pressurize, and press the epoxy resin into the coil. After the coil impregnation is completed, take out the container from the dipping tank. At this time, the coil is immersed in the container and the surrounding is filled with epoxy resin. It is necessary to take ...
