交流架空输电线路复合绝缘子故障诊断研究

摘要

交流复合绝缘子是架空输电线路上常见的元件,其内绝缘导通性缺陷难以检测而成为造成事故的主要因素。本文主要通过梳理分析国内外带电检测合成绝缘子技术现状和优缺点,并在充分解析分布电场法和红外测温法原理的基础上,建立了对应的交流复合绝缘子故障诊断数学模型,该模型在研制相关的带电检测装置的项目中得到了实施与验证。%AC composite insulator is common component on the overhead transmission line.The main factor causing accidents is that in insulators continuity and isolation defects are hardly detected.This paper mainly analyses the present status,merits and drawbacks of charged detection synthetic insulator technology at home and abroad.On the basis of fully developing the theory of distribution electric field method and infrared measuring system,fault diagnosis mathematical model is established for the corresponding AC composite insulator.This model is implemented and verified in the project of developing related charged detection device.
