变压器本体及套管色谱异常分析及处理

Analysis and treatment of abnormal chromatograph of transformer body and bushing

油色谱分析是充油电气设备故障诊断的主要手段之一。结合几起变压器及套管色谱数据异常,通过数据分析初步判断其内部故障类型。采用排除法依次检查各部位,找出故障原因,并对其进行分析,提出相应反事故措施。

The chromatographic analysis of oil is one of the main methods for fault diagnosis of oil-filled electrical equipment.Combined with several cases of abnormal chromatographic data of transformer and bushing,the internal fault types are preliminarily judged by data analysis,and the exclusion method is used to check each part in turn to find out the causes of the faults.The fault causes are analyzed and corresponding anti-accident measures are proposed.
