摘要
总结了现有低压串联直流电弧检测方法中检测参量如电压电流变化、弧声信号、电磁与光辐射信号的特征,深入分析了阈值法和基于单一检测参量的模式识别方法的特征及其局限性,展望了基于多参量综合的信息融合法的研究前景。
The features of detection parameters such as voltage and current variation, arc sound signal, and electromagnetic and light radiation signal in present low voltage series DC arc detection methods were summarized. The characteristic and limitation of threshold methods and pattern recognition methods based on single parameter were analyzed, and the research prospect of information fusion method based on multiple parameters was proposed.
