| 摘 要： | 提出了一种基于高频信号的电弧故障识别方法。通过天线接收电弧故障的高频信号,利用电弧故障发生时产生的高频信号的三阶累积量和四阶累积量发生的变化进行电弧故障识别。试验表明,电弧故障发生时辐射的高频信号的三阶累积量呈现明显的负偏态,四阶累积量呈现明显的正偏态,通过该方法可以很好地对电弧故障进行识别。

| Abstract: | The arc fault identification method was proposed based on the high frequency signals. The high frequency signal from the arc fault were received by the antenna,the variation for its third-order cumulants and fourth-order cumulants can be used to identify the arc fault. Experiments show that the third-order cumulants of the high frequency signals are taken on approximately negative skewed distribution and with approximately positive skewed distribution for its fourth-order cumulants when the arc fault happens,this method is effective for arc fault identification. |
