摘　　要：TF线圈为大型“D”形轮廓,由高、中、低场线圈通过套装和堆叠而成.需要分别对高中低场线圈进行绝缘处理,套装后填充高中低场之间的间隙(10 mm~120 mm),包绕对地绝缘后,再对间隙填充层进行绝缘处理.为了充分验证绕组制造的工艺,采用一个以中场绕组尺寸的Dummy绕组进行真空压力浸渍(Vacuum Pressure Impregnation, VPI)完成线圈绝缘.针对VPI过程中真空环境、外部压力、固化温度、时间控制等方面的技术难点,完成TF Dummy线圈VPI系统设计.采用CATIA软件对Dummy线圈VPI系统进行建模,合理设计子系统,有效缩短VPI过程的时间,保证绝缘质量.通过每个子系统的理论分析计算,更精确地选择VPI系统配备的设备型号,CFETR TF Dummy线圈VPI系统的设计和相关工艺的验证对后续TF线圈制造至关重要.TF coil is gigantic"D"shaped,composed by high,medium and low filed coil,via embedding and stacking.It is necessary to insulate the high,medium and low field coils respectively,fill the gap between high,medium and low fields(10mm~120mm)after embedding,wrap the ground insulation,and then insulate the gap filling layer.In order to fully validate the manufacturing process of the winding,a Dummy winding with a mid field winding size was used for vacuum pressure impregnation(VPI)to complete the coil insulation.To address technical difficulties such as vacuum environment,external pressure,curing temperature,and time control in the VPI process,a TF Dummy coil VPI system design has been completed.Using CATIA software to model the Dummy coil VPI system,designing subsystems reasonably,effectively improving the VPI process time and ensuring insulation quality.Through theoretical analysis and calculation of each subsystem,it is crucial to more accurately select the equipment model equipped with the VPI system.The design of the CFETR TF Dummy coil VPI system and the verification of related processes are crucial for subsequent TF coil manufacturing.
