摘　　要：针对上海发电机厂自主开发的百万千瓦级四极核电发电机的定子相线圈与并联环球形接头连接结构,结合具体冷却条件,采用顺序式耦合计算方法进行了"电-热"耦合场有限元计算分析,计算结果可为定子线圈与并联环连接结构的设计提供计算依据,也可为结构的进一步优化设计提供参考。Against the stator phase coils of the 1 100 MW 4-pole nuclear turbine generator and connected par-allel ring with it developed by Shanghai Electric Power Generator Equipment Co., Ltd Generator plant, a sequential electromagnetic-thermal field coupling calculation method was employed to carry on the analysis on ″Electric-thermal″ coupling field by means of finite element method, combined with the practical cooling condition. The calculation could offer the calculated evidence for designing the parallel ring construction connected to the stator phase coil as well as a basic analysis to optimize the generator design.
