摘要
低压故障电弧产生持续燃弧是诱发电气火灾的最重要原因之一.因此,减少低压电器故障电孤产生的危害性,最有效的方式是通过故障电弧保护装置减少切断电源前故障电弧持续存在时间.在简要介绍了低压电孤故障断路器(AFCI)的基本工作原理与应用的基础上,提出了对故障电孤的检测、控制精度与效率是影响低压电弧故障断路器性能的关键与核心.随后重点阐述了故障电弧检测的方法与技术手段,以及智能化检测与控制的研究进展.最后对智能化低压电孤故障断路器应用进一步智能化发展方向进行了展望.
Abstract
As one of the most important factors,it generates the continued arcing induced by the low voltage fault arc.Thus,the most efficient method to decrease the hazard of the fault arc with low voltage electric device is to minimize the duration time of the fault arc before shutting down the power by the protecting equipment of fault arc.Based on an investigation into the basic working principle and the application with low voltage AFCI,this paper proposes the detection of the fault arc as the core influence on the performance of low voltage AFCI,the control accuracy and efficiency as well.Furthermore,it introduces the technology of detection method with fault arc,the research development of the intelligenized detection and control on the key point.Finally,it offers the further intelligenized advance with the intelligenized low voltage AFCI.
