摘要
针对启备变在受电过程中发生的故障,从故障录波图形着手,采用频谱分析的方法,判断出了故障发生的原因,准确而及时地定位了故障点,为事故抢修和及时送电争取了时间,提高了电厂厂用电系统供电的可靠性。
Aiming at the fault occurred in the charging process of the standby transformer,starting from the fault recorder graphics,and by the method of frequency spectrum analysis,this paper found the reason for the failure, timely and accurately located the fault point. This saves time for emergency repair and timely transmission,and im-proves the reliability of power system of power plant.
