摘　　要：文章分析了大型汽轮发电机定子线棒端部受力情况 ,指出当发电机线棒产生二倍频振动时 ,定子绝缘所受到的各种危害。为了消除危害发电机安全运行的隐患 。Based on analyzing the forces on the end winding of large turbo-generator stator, the authors points out that the double frequency vibration produced by the stator winding bars is very harmful to the stator insulation. To eliminate this potential unsafely factor of the generator, a double frequency measurement of stator end winding and its integrated model test are introduced.
