| 摘 要： | 在对原故障电弧检测方法进行研究和总结的基础上，根据故障电弧发生时电流波形呈现的随机性特点，提出了一种基于差值一均方根法的故障电弧检测方法。经过不同负载、不同功率条件下的大量试验，结果验证了该方法能有效区分故障电弧和正常电弧，以及扰乱负荷，简单可靠，具有重要的理论价值和实际意义。

| Abstract: | Based on the research and summary of the previous method of arc-fauh detection, an arc-fauh detection method based on difference-root mean square method was put forward to deal with the randomicity of current waveform when the arc-fauh has happened. After a number of experiments verification under different load and power conditions, this method can distinguish normal arc from arc-fault and disturbing load effectively, and it is easy and reliable, also has the important theoretical and practical value. |
