避雷器运行状态的在线监测及专家诊断系统

On-line Monitoring of Arrester Running State and Expert Diagnostic System

描述避雷器在线监测的发展现状以及目前采用的主要测量方法,然后提出避雷器在线监测专家诊断系统的概念,利用避雷器在线监测仪实时采集避雷器泄漏电流、温度和母线电压等数据,建立避雷器泄漏电流与温度影响因素的数学模型,给出相关的诊断算法,最后利用C语言实现了专家诊断系统,从而为避雷器运行状态提供了一种行之有效的在线监测方法。

Describes the development status of arrester on-line monitoring and the main measurement methods currently,then the concept of arrester line monitoring expert diagnostic system,the use of arrester on-line monitor that real-time collects leakage current,temperature and bus voltage and other data,the establishment mathematical model of arrester leakage current and temperature affecting factors,the related diagnosis algorithms are given,and finally the expert diagnostic system is implementation which uses C language,then provides an effective on-line monitoring method for arrester running state.
