XLPE电力电缆附件局部放电测量与分析
为研究XLPE电力电缆附件现场常见典型缺陷的放电特征,在3根电缆实体上分别设计制作了中间接头尖刺、主绝缘划伤和终端头应力锥错位3种放电模型,建立了基于PDBase的局部放电测量分析系统。对比研究了3种典型缺陷的局部放电特征,分析了放电次数相位分布谱图Hn（φ）、放电最大幅值相位分布谱图Hqmax（φ）和放电幅值分布谱图H（q）3种统计特征。试验结果表明,不同缺陷类型其放电发展过程不尽相同,呈现的PRPD谱图、单个脉冲波形、相位分布趋势及统计特征区别明显;而同一缺陷在相同条件下其放电特征呈现出相似规律且重复性好;这些特征为进一步开展电缆附件放电机理研究及放电类型的模式识别提供了有力的试验依据。...

| Abstract_FL | In order to study the partial discharge ( PD) characteristics of the typical defects in XLPE pow-er cable accessories ,three PD models as tip defect of middle joint ,void defect in main insulation and dis-location of stress cone were designed on the cable entities ,and then the PD measurement and analysis sys-tem based on the PDBase was established .The PD characteristics of three typical defects were detected and compared,and the statistical features of Hn(φ),Hqmax(φ) and H(q) were investigated.The experi-mental results indicate that it has the high stability and repeatability of the discharge on the identical de -fect model under the same condition .The discharge development process ,PRPD patterns,time domain waveforms,central phase changing of PD signals and statistical features have very similar distribution characteristics and those of different defect has different ones .So it provides a test basis for the recogni-tion of PD types and a deeper study of the PD mechanism of cable accessories . |
