摘要
描述了故障电弧的危害、定义及检测方法分类。提出了一种基于Daubechies 4阶小波变换的故障电弧检测方法。通过试验分析证明,其具有计算简单、实时性强等特点,能有效检测线路中是否有故障电弧产生。
This paper described the harm and the definition of the arc fault, and illustrated the classification of arc fault detection. Then it proposed a kind of arcfault detection based on Daubechies 4 orders wavelet transformation. The analysis of experiments shows that the detection method is simple and real-time and can detect the arc-fauh in the lines effectively.
