摘要
在带电状态下展开局部放电检测是分析和判断开关柜绝缘状况的有效手段.分析了用户在实际巡检过程中存在的问题,阐述了侵入式局部放电监测系统的分布式构架,介绍了系统构成及基本功能.系统的应用实现了开关柜局部放电全寿命周期监测自动化,解决了开关柜绝缘状态分析对数据“量”的需求问题,为用户开关柜检修决策提供支持.
Abstract
Live detection of partial discharge (PD) is an effective way to analyze and judge the insulation state of switchgear.This paper analyzes the existing problems during PD inspection,expounds the distributed framework of invasive PD monitoring system,and introduces the system structure and basic functions.System application realized the full life-cycle monitoring automation for switchgear PD,solved the demand for data "quantity" by the switchgear insulation state analysis,providing support for user's decision-making in switchgear maintenance.
