摘　　要：针对某110 kV变压器在运行过程中油中溶解乙炔和氢气含量超标报警情况,根据已知变压器绝缘油色谱数据变化趋势、变压器的检修状况和试验数据,采用三比值法分析变压器绝缘油中溶解的乙炔和氢气等气体含量超标的原因。找到潜在故障,并提出解决方法,从而保证变压器的稳定运行。During the operation of a 110 kV transformer,the content of dissolved gas acetylene(C 2H 2)and hydrogen(H 2)in the oil exceeded the standard.According to the known trend of chromatographic data of transformer insulating oil,the maintenance status and test data of transformer,the three-ratio method is used to analyze the reasons for the excessive content of dissolved acetylene and hydrogen in transformer insulating oil.Potential faults are found and solutions are proposed to ensure the stable operation of the transformer.
