摘　　要：综述了目前故障电弧检测的研究内容、成果及发展方向。指出低压配电柜和家庭供配电系统各自产生故障电弧时所表现的物理特征不同,使得各自的故障电弧检测方法有所差异。分别讨论了了基于电弧数学模型、电弧物理现象和电流电压波形的电弧检测方法。The present research, achievement and developing trend of fault arc detection were overviewed. That difference existed in fault arc delection because of the different physical characteristics of low voltage power distribution cabinet and home power supply and distribution system when fault arc occurred was indicated. Arc detection ways were discussed respectively based on arc mathematic model, are physical phenomena and current/voltage waveforms.
