| 摘 要： | 本文用有限元法计算了大型水轮发电机定子最热段的三维温度场，给出了不同电压等级，不同槽形尺寸，不同定子电流密度和不同定子轭部磁密时检温计的温度修正曲线。利用这些曲线，即可从检温计的批示温度推算出定子最热段绕组铜线最高温度值和平均温度值。

| Abstract: | In this paper,3D temperature field of the hottest region in the stator of hydroelectric generator is calculated by means of finite element method.Temperature correc tion curves of thermodetector with different voltages,different sizes of slot,different current densities and different magnetic-flux densities of stator yoke are given.Using these curves,the highest and average temperatures of stator winding can be calculated from the thermodetector indication. |
