摘要
局部放电检测是XLPE电力电缆绝缘状态检测的主要方法之一.提出了一种基于馈路终端单元的XLPE电缆局部放电在线检测的新方法.利用改进型罗戈夫斯基线圈传感器解决频带窄的不足,同时基于馈路终端单元通过WAN进行信号传送.经实验检验,该系统具有频带宽、体积小、实时信号传送方便等优点.
Partial discharge monitoring is one of the main methods to inspect An online monitoring and diagnostic new method to inspect XLPE cables＇ partial the cables＇ status. discharge based on Feedback Terminal Unit （FTU） is established. The improved Rogowski coil sensor is used to overcome the disadvantage of low bandwidth, and WAN is used to send the signal based on FTU. The experiment done in this paper proves that this system has wide bandwidth, small size and convenient real-time signal transmission advantages.
