摘要
本文介绍一种基于分、合闸线圈电流波形分析的断路器机械缺陷判断方法,阐述该方法的基本原理,并根据某变电站的实际应用情况验证该方法的有效性,最后针对该方法提出不足之处及后续研究方向。
The method of judging breakers mechanical defects based on opening /closing coil current waveform analysis is introduced and the basic principle is explained in this paper. The effectivity of this method has been verified by the practical application in a transformer substation. Finally,the deficiency of this method and future research directions are pointed out.
