摘　　要：向家坝电站单机额定功率800MW是世界上最大的水轮发电机组,设计、生产者根据分析选定额定电压23kV,也是水轮发电机最高的电压等级,目前尚没有其绝缘系统及定子线棒设计制造和运行经验,属于全新开发设计。根据对定子线棒结构设计的论证和发电机定子线棒相关的各项试验等验证,23kV发电机出口电压选择是合理的。The 800 MW hydro-turbine generator unit in Xiangjiaba Hydropower Station is the largest hydro-turbine generator unit in the world. The rated output voltage designed by Tianjin Alstom Company is 23 kV,which is also the highest. The design,manufacture and operation of the stator bar and the insulation system are new and challenging topics,in which no experience is available. With the analysis of the structural design of the stator bar and relevant tests,the stator bar insulation and the designed output voltage are proved to be appropriate.
