摘要
介绍了某电厂350MW汽轮发电机转子绕组不稳定高阻多点接地故障的查找方法,接地故障的原因分析,为保证修复质量,除了按预试规程要求进行试验外,结合现场实际提出了"测量转子两极阻抗电压"对比的方法。
The search method and the analysis of causes of rotor windings unstable high resistance multi - point ground fault of a 350 MW turbo - generator in a power plant was describd. To ensure the repairment quality, in addition to regular tests conducted as required by pre - voltages of two poles of rotor windings is proposed on trial procedures,the way of measuring the impedance the basis of the actual situation.
