摘　　要：提出了一种基于网格分形理论的故障电弧诊断方法。根据任意时刻正常工作电流和故障电弧电流斜率的不同变化特征,通过计算相邻电流斜率之间的关系,判断电流的突变点或电流波形的畸变点,由此对线路中可能出现的故障电弧作出诊断。This paper presented an arc-fault diagnosis based on fractal theory Grid fractal. According to the different variation of the normal operating current at any time and the slope of the arc-fauh current, the method then determines the mutation point of the current or current waveform distortion point by calculating the relationship between the adjacent current slope, thus makes a diagnosis to the possible arc-fauh in line.

关 键 词：故障电弧 网格分形 电流斜率 波形畸变诊断
