摘要

根据某水电厂500 kV充油电缆的运行方式

提出了500 kV充油电缆局部放电在线监测系统的整体方案

研制了整个在线监测系统的硬件和软件

开发了500 kV充油电缆局部放电在线监测系统

已投运于该水电厂A厂AB联络线500 kV充油电缆出线端终端的在线监测。监测结果表明

该系统不但可以准确计算、显示7个放电参量

并且可以显示4种放电谱图

能有效地判断绝缘的放电状态。

Abstract

According to operating characters of 500 kV oil-filled cable of a storage power station

the integrated scheme of on-line partial discharge monitoring system for 500 kV oil-filled cable is presented in this paper.Moreover

the all hardware and software of system are developed.The system had been applied on the AB link line terminal of a station of the storage power station.The monitoring results indicate that the system not only can calculate and display seven discharge parameters exactly

but also can display four charts

furthermore

can estimate discharge states of insulation effectively.
