中文摘要: 分析了当今交联聚乙烯(cross-linked polyethylene,XLPE)电力电缆局部放电信号识别的几种主要方法的优缺点及其适用条件,以及相位分辨数据统计法的局限性.并对基于等效带宽-等效时间长度的簇分离方法的应用有效性的关键技术进行了剖析,对该方法的进一步研究及局部放电在线测量的应用提出了建议.
Abstract:Several present signal identification techniques for partial discharge signal ( PDs) ofXLPE cables are analyzed,namely,their advantages and disadvantages and their application range.Moreover,limitations of the phase-based statistic technique are interpreted in detail. Clusterclassification technique based on the equivalent bandwidth-equivalent time length( W-T) is likely todevelop in a desirable manner for PDs identification. The important aspects of this technique areanalyzed,which may offer reference for further study of this technique and for the on-line PDmeasurement.
