摘要
故障电弧是造成电气火灾的重要原因。通过电气火灾故障电弧的成因分析,对故障电弧探测技术进行了系统阐述和技术研究,结合故障电弧电流波形的时域和频域特征,提出了一种基于随机森林算法的故障电弧探测技术的设计方法。
Fault arc is an important cause of electric fire. In this paper, the fault arc detection technology is systematically expounded and studied by analyzing the causes of electric fire fault arc. Based on the characteristics of time domain and frequency domain of fault arc current waveform, a design method of fault arc detection technology based on random forest algorithm is proposed.
