摘要
对故障电弧的产生原因进行了分析,列出了故障电弧探测装置的相关标准。分析了不同负载下电弧故障时电流和电压的特性,比较了几种常用检测故障电弧的应用算法,阐述了与电弧故障断路器的不同之处并按安装位置进行设计分类。最后对故障电弧探测装置的发展进行了分析。
The cause of arc fault was analyzed. The relevant standards of arc fault detection device （AFDD） were listed. The current and voltage characteristics in arc fault under different load were described. Several common arc fault detection algorithms were compared. The difference of AFDD with are fault circuit interrupter was descibed and AFDD was designed and categorized according to the installation location. The development trend of AFDD was analyzed.
