摘要
汽轮发电机组定子线棒冷却水的堵塞是水冷发电机定子常见的问题。通过测水流量法,对发电机定子线棒和出线套管引水管冷却水的流量进行测量,并通过热水流试验法,对发电机定子冷却水进行热水流试验。试验数据表明,各管束水流量偏差均小于标准要求,定子线圈出水温度随时间的变化趋势具有良好的一致性,说明发电机定子线棒冷却水具有良好的流通情况。汽轮发电机定子线棒冷却水流通性的试验研究,对于发电机定子线棒内部堵塞的分析和处理,发电机的安全运行具有十分重要的意义。
The frequent problem occurring to turbine generator’s stator with water cooling system is stator bar’s clogging.The cooling water flow rate of the generator stator bar and the outlet bushing is measured by the water flow measurement method,and the hot water flow test is performed on the generator stator cooling water by the hot water flow test method.The test data shows that the water flow deviation value of pipes is less than the standard requirement value,and the variation trend of the stator coil outlet water temperature with time has good consistency,indicating that the generator stator bar cooling water has good circulation property.The experimental study on the flow circulation property of stator bar cooling water of generator is of great significance for the analysis and treatment of internal clogging of generator stator bars,and the safety of the turbine generator operation.
