基于局部放电频谱分析的XLPE电力电缆在线监测技术
On line detection in XLPE power cables based on spectrum of partial discharge
【摘要】 基于局部放电频谱特性分析 ,本文提出在甚高频 (VHF)检测XLPE电力电缆的局部放电量 ,并研制出可应用于XLPE电力电缆运行状态现场在线检测新技术。试验结果表明 :该技术在10kHz 2 8MHz频率范围内可检测XLPE电力电缆本体或附件中小于 1pC的局部放电信号
【Abstract】 Technique of partial discharge detecting at VHF in XLPE power cables based on spectrum analysis of partial discharge was put forward and applied to on\|line cables monitor in this paper. Test results proved that 1pC partial discharge signal may be detected at 10kHz\|28MHz frequency range by this technique.
