摘要
通过油中溶解气体在线监测装置发现变压器内部故障,利用色谱分析试验结合高压电气试验对故障性质及故障点进行分析判断,并对故障进行了及时的处理,避免了一起主设备重大事故的发生。
Internal faul of the transformer is detected out by the on-line monitoring device of dissolved gas in oil,and then the fault features and points are analyzed and diagnosed through the chromatographic analysis test and high-pressue electrical test.Then,the fault can be treated in time,to avoid the occurrence of a grave accident of main equipment.
