Description
技术领域
本发明涉及控制棒驱动机构用电磁线圈领域，具体是一种耐辐射耐高温的控制棒驱动机构保持线圈组件及其制法。

发明内容
本发明的目的在于提供一种耐辐射耐高温保持线圈组件及其制法。
本发明是这样实现的：一种耐辐射耐高温保持线圈组件，包括磁轭、骨架、线圈、骨架挡板、引线管、法兰，磁轭内设有绕线骨架，骨架外侧间隔设置若干圈骨架挡板，磁轭两端焊接法兰，引线管焊接在一侧法兰上，线圈绕在骨架上，线圈骨架外侧、线圈挡板两侧及磁轭内侧有绝缘层，每层线圈之间填充绝缘层。
进一步地，所述线圈的采用镀银抗氧化铜导体，线圈外径≤2mm。
进一步地，所述绝缘层为云母包覆材料绕缠而成。
另外，耐辐射耐高温保持线圈组件的制法：1）绕线前的绝缘处理：线圈骨架外侧和骨架挡板两侧，使用云母包覆材料包覆处理；2）绕线：使用自动绕线机，配用0.6～2.0张力器绕线；3）层间处理：每层线圈层间用绝缘包覆材料缠扰隔开；4）绕线后绝缘处理：线圈绕制完成后，线圈最外层与磁轭之间间隙使用云母包覆材料包覆至填充无空隙；5）焊接封装：引线管焊接在一侧法兰上，然后磁轭两端用法兰焊接封装。
进一步地，法兰与磁轭、法兰与引线管处均采用氩弧焊焊接。
与现有技术相比，本发明的有益效果是：采用线径小的镀银抗氧化铜导体，降低绝缘层厚度，解决控制棒驱动机构保持线圈因骨架空间限制，而无法按照设计要求的线圈匝数绕制的问题，同时能降低线圈发热量，性能明显提升，本发明使线圈之间充分被绝缘层填充固定，解决控制棒驱动机构保持线圈使用时，因交替产生的电磁力，导致的线圈松动现象，提高装置可靠性。
