110kV及以上电流互感器损坏事故分析及对策

Strategy and Accident Analysis on Current Transformer Damage of 110 kV and Above

通过对1991年以来江西省110kV及以上电流互感器事故情况的分析,对电流互感器的绝缘结构特点、常见故障,以及电流互感器油中溶解气体色谱分析方法的特点、预防性试验本身存在的不足及对策等进行了论述,扼要说明了对电流互感器绝缘状况进行正确分析判断的方法。

Through analyzing the cunvnt transformer accident situation of 110 kV and above form 1991 in Jiangxi,make discussion on structure character and common fault of current transformer,character,shortage and strategy of dissolved gas chromatogram analysis method in oil of current transformer,explain the method of correctly analysis and diagnosis on insulation condition of current transformer.
