摘要
本文主要阐述气体绝缘组合电器(GIS)外壳几种典型振动的频率特性,尤其是在交变电场下自由导电粒子的运动和局部放电所引起的外壳振动的频率特性,研究GIS的内部气压、电极形状、电场强度等的变化对振动频谱的影响,初步建立一个利用振动频谱来预报GIS内部潜伏性故障类型及严重程度的监测系统。
, This paper presents several typical frequency characteristics of vibration on the metallic enclosure of GIS, especially the characteristies of vibration caused by free conducting particles and partial discharge under alternative voltage. The paper also presents investigation results with contaminants under different SF6 gas pressure, shapes of the electrodes and electrical strength. An inspective system which can predict internal latent faults of GIS by frequency spectrum has been built.
