摘　　要：为了解决SF_6气体绝缘设备故障识别和状态评价问题,阐述了局放下的SF_6气体分解机理,建立了126 kV GIS装置的SF_6气体分解产物试验平台,提出了SF_6气体分解物检测方法,在GIS模拟试验装置内进行了局部放电试验。试验结果表明,SF_6气体分解物检测方法能够准确检测、分析绝缘电气设备中SF_6气体分解产物的种类和含量变化情况,解决了SF_6气体绝缘设备故障诊断不准确、状态评价缺乏试验依据等问题,为运行设备突发故障提供了快速有效的故障定位方法。In order to solve the problem of SF6 gas insulated equipment in fault identification and status evaluation, the SF6 gas decomposition mechanism in partial discharge is expounded, test platform of SF6 gas decomposition product for 126 kV GIS device is set up, method of detecting SF6 gas decomposition is proposed and partial discharge test is taken in the GIS modeling experimental equipment SF6 gas decomposition can accurately detect and analyze changes The test results show that the method of detecting of species and quantity of SF6 gas decomposition product in insulated electrical equipment solves the problems of which fault diagnosis is not accurate and state evaluation is lack of experimental basis for SF6 gas insulated equipment, providing a rapid and effective method of fault location for emergency equipment failure when in operating.
