摘　　要：目前,水轮发电机组的容量发展到了1 000 MW量级,其几何尺寸和工艺难度越来越大,因而对水轮发电机部件的布置及其工艺质量也随之提出了更高的要求。为了减少发电机部件布置和工艺方面的难度,着重探讨了水轮发电机定子线棒的并头方案对定子尺寸的影响以及对工艺方面的要求。通过实际工程案例,对定子线棒的2种典型并头结构进行了对比分析,根据分析结果,提出了相应的建议和措施,以供技术人员在设计、制造和安装时作出相应的选择。At present,the capacity of hydro- generator unit reaches 1 000 MW level,the geometrical size and technical difficulty of hydro- generator increases,resulting in higher requirements for the arrangement of hydro- generator components and its technical quality. In order to reduce the difficulty of arrangement and techniques,we discuss the influence of different connection schemes of stator bar on the size of stator and related technical requirements. In a practical project,we compared and analyzed two typical connection schemes. Based on the results of comparison,we put forward suggestions and measures for connection structure to provide reference for technical personnel in design,manufacture and installation of stator bar.
