摘要
基于直流故障电弧较交流故障电弧所存在的独特特征,强调了直流故障电弧研究的差异性,阐述了目前工程实践工况下导致不同类别直流故障电弧的原因。以时域、频域、时频域的视角讨论了现有的直流故障电弧检测方法,指出了直流故障电弧建模、产生、定位等多个延拓研究层面,更进一步地强调了直流故障电弧检测多信息融合的趋势及其多类型甄别、精确定位等问题。
Comparing with the AC arc fault, the characteristics of the DC arc fault were presented, and the reasons for different types of DC arc fault under various actual working conditions were analyzed. Then the current detection techniques for DC arc fault were discussed based on the time domain, frequency domain and time-frequency domain methods. Finally, the development trend of the DC arc fault was pointed out, including its modeling, occurrence mechanism, location, and the applications of the multi-information fusion detection and multi-type recognition.
