| 摘 要： | 变压器过热故障在变压器运行故障中占很大比例，它促使绝缘材料老化分解甚至烧坏金属部件，因此，过热故障如果不能及时发现，将会造成设备损坏酿成事故。文章针对古城变电站1—4#整流变压器内部过热故障，通过常规试验和油中溶解色谱分析查明了故障原因，并详细介绍了这起事故的处理过程。

| Abstract: | The overheat fault of transformer takes large portion on transformer's operation fault,it forces insulation material's aging,resolution,even destroyed metal part.Therefore,if the overheat fault can not be found in time,it will make device destroyed.According to the internal overheat fault of 1-4# rectifier transformer on Gucheng substation,the paper founds out the fault reason by common test and chromatographic analysis,and introduces the fault's treatment process in detail. |
