摘　　要：某大型电站1号机组发电机站内开机试运行时,发电机集电环室内出现金属撞击异音的异常现象,针对异音产生后声响分布的位置进行分析、检查及排除,由简入繁、由易入难,并最终确定异音产生的部位为发电机上导油槽接触式油挡碳精块在机组运行过程中无法随轴领径向跟随所导致。在分析、排除异音过程中针对发电机各部位的检查流程、原因锁定也为其他电站发电机相类似异音产生后的分析、处理提供了详实的指导及借鉴。During the commissioning of generator station of the#1 unit of a large hydropower station,the abnormal phenomenon of metal impinging on the abnormal sound in the generator collector ring was found.The distribution position of the abnormal sound was analyzed,checked and eliminated,which was from simple to complex and from easy to difficult.And it was ultimately determined that the cause of the abnormal was that the oil guide groove contact oil baffle carbon block in the process of unit operation cannot follow the radial direction of the shaft collar.In the process of analysis and elimination of abnormal sound,the inspection process and cause lock for each part of the generator also provide detailed guidance and reference for the analysis and treatment of similar abnormal sound caused by the generator of other hydropower stations.
