【Abstract】 As the main protection for transformers,the gas protection can effectively reflect the internal faults of a power transformer. Taking a power main transformer A-phase tripping and gas protection operating as an example,this paper introduces the accident process, using chromatography analysis method to analyze and judge the fault characteristic gases,and find out the accident causes,and finally puts forward the corresponding treatment measures and suggestions for prevention of the similar accidents from occurring in the field.更多还原
