GIS局放特高频在线监测系统的应用

摘要

气体绝缘组合电器GIS在城市电网中得到广泛应用，建立GIS局部放电在线监测系统，对准确掌握设备内部绝缘运行状态和指导检修具有重要意义。本文主要讨论了GIS局部放电产生的原因、GIS局部放电监测的方法、基于特高频检测原理的局放在线监测系统的结构和软件功能以及在工程设计中应该注意的问题。%Developing of GIS Partial Discharge UHF On-line Monitoring System is important for pinpoint holding of insulated run-state in GIS and coach-overhaul,As broad application of gas insulated switchgear in city electric wird.This paper introduces cause of prtial dscharge and measurement of prtial dscharge in GIS ,and instruct of GIS Partial Discharge UHF On-line Monitoring System,and attendant problems in egineering design.
