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-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。
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.
