摘要 介绍了电弧故障检测的基本原理。分析了电弧故障检测技术的现状、难点及其技术应用。通过对串联电弧故障波形和并联电弧故障波形特征的研究,提出了电弧频谱分析方法,既有助于电弧特征的研究,又有助于提高电弧故障检测的可靠性,是电弧故障检测的有力手段。 This paper introduced the basic principle of arc fault detection(AFD). The current situation and the difficulty of AFD technology and its application were analyzed. Wave characteristic of series-arc fault and parallelarc fault were discussed respectively. The frequency spectrum analysis was proposed to improve the reliability of AFD. It is an effective means of arc AFD ,which is helpfull to the research of arc characteristics.
