中文摘要: 在建立发电机定子线棒横断面温度场数学模型的基础上,以某台600 MW发电机的定子下层线棒为研究对象,分析了发电机空心股线堵塞与否时的温度场分布.结果表明,空心股线堵塞会不同程度地影响定子线棒的温度分布.
Abstract:Based on the heat transfer model of the generator stator bars，the temperature field distribution of the generator stator bar on cross section is analyzed. As the object of study，the lower bar of one 600 MW generator stator is analyzed to obtain the temperature distribution on the stator's cross section at the two states，namely，when the hollow strands are blocked and when they are not.The results show that when the hollow strands are blocked，the block will affect the stator bar's temperature distribution to different extents.
keywords: generator stator temperature field block hollow strand
