摘要
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。
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.
