The invention provides a fixing and sealing process method suitable for a high-temperature superconducting magnet coil, which comprises the following steps: paraffin fixing and sealing: placing a superconducting coil in a paraffin fixing and sealing mold of paraffin vacuum fixing and sealing equipment, and pouring paraffin into a paraffin pouring port of the paraffin fixing and sealing mold in a vacuum environment for fixing and sealing; demolding: after the paraffin in the molten state in the paraffin solid sealing mold is cooled and solidified, demolding the superconducting coil; and epoxy resin solid sealing: the demolded superconducting coil is placed in a coil box, the topmost cover plate of the superconducting coil is used for sealing the coil box, epoxy resin is poured into an epoxy resin pouring opening in the coil box, and all gaps between the superconducting coil and the coil box are filled with epoxy resin. According to the scheme, the superconducting coil is subjected to composite fixing and sealing of two materials by adopting a mode of combining paraffin inner fixing and sealing with epoxy resin outer fixing and sealing, so that the superconducting coil is protected by utilizing mechanical measures, the superconducting coil is unlikely to be subjected to vibration impact caused by operation of a maglev train, and thus the superconducting coil is protected.

    本发明提供的一种适用于高温超导磁体线圈的固封工艺方法,包括:石蜡固封:将超导线圈置于石蜡真空固封设备的石蜡固封模具中,在真空环境下向石蜡固封模具的石蜡浇注口内灌入石蜡进行固封;脱模:待石蜡固封模具内熔化状态的石蜡冷却固化后,对超导线圈进行脱模;环氧树脂固封:将脱模后的超导线圈放置到线圈盒中,超导线圈的最上层盖板用于封盖线圈盒,向线圈盒上的环氧树脂浇注口内灌入环氧树脂,使得灌入超导线圈与线圈盒之间的所有空隙填充满。本案采用石蜡内固封结合环氧树脂外固封的形式,对超导线圈进行两种材料的复合固封,从而利用机械措施实现超导线圈的保护,不易受到磁浮列车运行带来的振动冲击,从而实现对超导线圈的保护。
