摘要:
定子线棒换位技术是1 000MW水轮发电机设计中的关键技术之一,合适的换位方式有利于更好的减小定子股线间的环流损耗,提高电机效率。对水轮发电机常用的360°全换位、0°/360°/0°加槽部空换位段换位、不足360°换位、0°/360°/0°延长换位等4种换位方式进行讨论,采用漏感电势法分别计算4种换位方式下1 000MW水轮发电机定子股线环流损耗,对计算结果进行对比分析。结果表明,不同换位方式对环流损耗分布有较大影响,水轮发电机定子股线采用0°/360°/0°延长换位时环流损耗最小,约占360°全换位环流损耗的15.3%,不足360°换位次之,约占360°全换位环流损耗的25.9%。
Abstract:
The transposition technique of stator bar is one of the key techniques in 1000MW hydro-generator design,and the suitable transposition method can reduce the circulating current losses of stator winding better,and improve the efficiency.Four common transposition methods for hydro-generator were analyzed in this paper,including 360° bar transposition,0°/360°/0°bar transposition with void,deficient 360° void bar transposition and 0°/360°/0° extended bar transposition.The circulating current losses ...
