一起220kV主变跳闸事故分析与探讨

Analysis and Discussion on a 220 kV Transformer Tripping Accident by Oil Chromatography

针对江苏220 k V某变电站1号、2号主变故障情况进行了分析,结合根据设备现场运行的具体情况,利用色谱判据分析故障性质,为正确诊断和处理故障提供依据,结合高压试验检查情况确定现场检修方案,并针对变压器的改造提出了建议。

Based on the accident occurred on NO.1 and NO.2 main transformer of 220kV substation in Jiangsu province, based on the practical situation of the equipment, this paper analyzes the fault property by chromatography, and further provides an important basis for the fault diagnosis and treatment. In addition, according to the High-voltage test examination situation, the field overhaul plan is determined, and the advice for the reform of transformer is also proposed.
