摘要
以1000MW级大型汽轮发电机定子线圈为例,采用漏感电势法对股线的漏磁感应电势和股间电压分布情况进行了研究,为胶化线圈绝缘结构设计、制造过程工艺改进及股间短路试验方法的优化等提供一定的理论帮助。
Taking stator coils in the 1000 MW largesize turbine generator as an example,the leakage potential method is applied to study the induction penitential of magnetic flux leakage and voltage distribution among coil strands,to provide theoretical assist in the fields of insulating system design for gel coils,technological improvement of manufacturing process and optimization of short-circuit test method in the strands.
