摘要(Abstract)：

在对某发电厂660 MW汽轮发电机的检查中发现定子铁芯背部有多处灼伤,经现场查看发现发电机铁芯背部存留毛刺,由于毛刺的存在,在运行中会使边段硅钢片间产生微小电压而发生跳火,进而导致局部过热灼伤。经模拟论证及现场处理后消除了缺陷,为后续发电机检修以及发电机定子灼伤问题的处理提供了参考。
Several burns were detected on the back of stator core during 660 MW steam turbine generator examination in a power plant. It is found that there are burrs on the back of stator core, due to which there comes small voltage between silicon steel sheet, and flashover thereby occurs and the stator core burn comes with partial overheat. Through simulation demonstration and field treatment, the defects are eliminated, which provides reference to generator maintenance and treatment on stator core burn of generator.
