摘要
发电机定子绕组汇流排是连接定子线圈的重要电气部件,汇流排损伤会导致发电机故障,威胁人员与设备安全.以某水电站 500 kV发电机定子绕组汇流排损伤问题为例,分析了汇流排绝缘磨损形成的原因,针对损伤问题提出现场处理措施.处理后的汇流排各项绝缘试验满足标准,此次原因分析及处理措施为类似汇流排损伤问题的解决提供经验.
Abstract
Generator stator winding busbar is an important electrical component connected to stator coil. Damage of bus-bars can lead to generator failure and threaten safety of personnel and equipment. In this paper,the causes of sink insula-tion damage in an actual 500 kV generator stator winding is analyzed,and treatment and pre-control measures for the damage problem were proposed.The repaired busbar meets insulation tests and the analysis provides experience for solu-tion of similar busbar damage problems.
