Abrégé
(EN)
The invention relates to a plug current lead structure and a superconducting magnet. The plug current lead structure comprises a fixed joint, a movable joint and a functional container with a functional cavity, the functional container is arranged between a superconducting magnet shell and a cold shield, one end of the fixed joint extends into the functional cavity, the functional cavity is used as a cooling cavity when the movable joint is inserted into the functional cavity and communicated with the fixed joint, and the functional cavity is used as a vacuum cavity when the movable joint is pulled out of the functional cavity and disconnected from the fixed joint. According to the plug current lead structure, the fixed joint is arranged on the cold shield, so that the problems of loose contact of junctions and resistance higher than safety values of the junctions are reduced when the structure enters a 4K environment from a 300K environment. Besides, as the heat capacity of the cold shield is higher than that of an internal structure of the cold shield, the risk of quenching in excitation and field reduction processes is reduced. In addition, the functional cavity has different functions when the movable joint and the fixed joint are in different states, heat conduction is reduced, and good heat-insulating properties are achieved.

本申请涉及一种插拔式电流引线结构及超导磁体,插拔式电流引线结构包括、固定接头、移动接头以及具有作用腔的作用容器,作用容器配置于超导磁体外壳与冷屏之间;固定接头构造为一端伸入作用腔内,移动接头插入作用腔内与固定接头连通时,作用腔用作冷却腔;移动接头拔出作用腔后与固定接头断开时,作用腔用作真空腔。本申请提供的插拔式电流引线结构,固定接头设置于冷屏上,从而降低从300K环境进入4K环境而导致结合处接触不紧密、结合处电阻大于安全值的问题;同时由于冷屏的热容大于冷屏内部结构的热容,从而降低励磁和降场过程中失超的风险。此外,作用腔在移动接头与固定接头不同状态时用作具有不同功能的腔,降低热传导并达到良好绝热性能。
