摘　　要：全路对HXD3型机车运行中主变压器油质量进行5项理化、电气性能指标的检测,未对介质损耗因数进行检测。由此,不易提前发现变压器油受潮、被污染、劣化、变质、老化等不合格情况,存在较大的潜伏性故障隐患。通过探究变压器油介质损耗因数的变化规律,得出介损检测的技术措施和介损不合格的处理方法,满足了机车主变压器油的安全稳定运行。Five physicochemical and electrical performance indexes of the main transformer oil quality in the opera⁃tion of HXD3 electric locomotive were detected by the entire railway,and the dielectric loss factor was not detected.Therefore,it is not easy to find out in advance the transformer oil moisture,pollution,deterioration,aging and other un⁃qualified conditions,that is concerned as a great potential trouble.By exploring the variation rule of dielectric loss of transformer oil,the technical measures of dielectric loss detection and the disposal method of disqualification are ob⁃tained,which can satisfy the safe and stable operation of locomotive main transformer oil.
