【摘要】 通过进行发电机有功负荷、转子电流(无功)、发电机转子冷却水温试验以及瞬态试验,诊断出励磁机振动故障的根本原因为发电机-励磁机联轴器不对中。采取现场重新铰孔找中的方法,成功消除了励磁机的振动故障。更多还原

【Abstract】 Analysis of vibration data measured in generator load test, generator current test, cooling water temperature test and coast-down test reveals that the root cause of exciter rotor vibration is the generator-to-exciter coupling misalignment. Field re-alignment of the coupling eliminate the vibration problem.更多还原
