摘要(Abstract)：

通过对变压器绝缘油的气体含量检测,结合电气试验结果,综合分析一起变压器内部过热故障,及时发现了绕组绝缘损坏的隐患,可为变压器运行中此类故障的诊断和处理提供借鉴。
By testing gas content in insulating oil of transformer,the paper,in combination with an electrical test,comprehensively analyzes an internal overheating failure of transformer and expounds the analysis steps,fault causes and treatment scheme,providing reference to diagnosis and handling of such faults during transformer operation.
