摘要
分析大型水电站发电机、电压互感器、高压厂用变压器、厂用电母线及异步电机等电气设备常见典型电气故障的录波波形特征,为现场运行和检修人员定位故障点、隔离故障间隔及设备检修提供决策依据。
Analysis is conducted on the fault wave characteristics of common and typical electrical faults occurred in electrical equipment such as generators,voltage transformers,high-voltage auxiliary transformers,auxiliary buses and asynchronous motors,which offers a decision-making basis for on-site operation and maintenance personnel to locate fault points,isolate fault intervals and perform equipment maintenance.
