摘　　要：近年来发电机定子底脚载荷试验已成为火电招标中的一项关键技术要求,能确诊发电机振动故障是否因底脚载荷分配不合理导致。文章基于某百万电厂发电机10W振动大故障案例,重点介绍发电机定子机座四角载荷分配试验方法并通过底载试验数据分析,精确调整底角载荷分配,有效减震。In recent years,the load test of generator stator foot has become a key technical requirement in thermal power bidding,which can determine whether the vibration failure of generator is caused by the unreasonable load distribution of the foot.Based on the 10W vibration fault case of a generator in a million power plant,this paper focuses on the test method of load distribution at four corners of the stator frame of the generator,and through the analysis of the bottom load test data,it can accurately adjust the load distribution at the bottom Angle and effectively reduce the vibration.
