摘要
高压XLPE电缆是电力系统的重要组成部分,通过监测电缆绝缘的局部放电,可以有效地判断电缆的电树枝老化状况,实现状态维修,这对电力系统的长期稳定运行具有重要意义。为此,文中设计了一种基于ARM9的嵌入式便携电力电缆局部放电监测系统,具有便携、易于接入网络、低成本的特点,适合于野外作业。
The high voltage XLPE power cable is a very important part of the power system. The degree of electric-tree aging in the cable can be estimated effectually by measuring partial discharge and state maintenance can therefore be realized, which is of great significance to the long term stable operation of the power system. An embedded partial discharge monitor system of XLPE power cable is developed based on the ARM9. This system has the ad- vantages of portability, easy access to the ethernet and low cost and is therefore suitable for the outdoor environment.
