以几个典型的故障录波图为实例,介绍故障电流电压、相位和故障时间序列的计算,判断故障性质,揭示保护及开关设备在故障过程中动作的方法。指出正确解读故障录波图是准确处理事故,迅速恢复送电的有效手段,供继保及变电运行人员参考。
이궤개전형적고장록파도위실례,개소고장전류전압、상위화고장시간서렬적계산,판단고장성질,게시보호급개관설비재고장과정중동작적방법。지출정학해독고장록파도시준학처리사고,신속회복송전적유효수단,공계보급변전운행인원삼고。
With several typical fault waveform recorded as example,calculation of fault current,voltage,phase and time series of fault,the identification of fault,discovering the behaviors of protection and circuit breaker during the fault are introduced.It is point out that correct interpretation of fault waveform recorded is the necessary measure to accurate fault treatment,power supply rapid restoration.It would be reference for the colleagues of both substation and relay protection.
