摘要
结合在线监测试点(220kV沙田变、500kV邕州变)的主变压器油中气体在线监测应用情况,对试点变压器运行工况及故障诊断和实测数据进行分析,并对安装试点变电站的主变油中气体在线监测系统检测到的数据与常规检测法得到的数据进行比较,分析常规色谱和在线监测方法的利弊,总结了通过在线监测数据评估变压器绝缘状态的经验。经过1年多的运行表明,MGA2000-6系列在线监测系统运行较为可靠,测量数据较准确,能较正确地反映变压器的绝缘水平和运行状况,可作为主变状态维修的依据。
According to the application of oil gas online monitor of main transiormer at testing points （220kV shatian substation, 500kV Yongzhou substation）, the operation state and fault diagnose real data of tested transformers are analyzed. Advantages and disadvantages between traditional oil chromatogram method and online monitor method are analyzed based on the comparison between online monitor data and traditional measure data. Experiences obtained from the transformer insulator state estimation based on online monitor data are summarized. The over one year operation shows that MGA2000-6 series online monitor system had good operation reliability and accurate measured data, which can reveal the actual insulator level and operation state of transformer, and thus can become the basis of transformer state maintenance.
