Based On Oil And Gas Chromatographic Analysis Of Transformer Internal Fault Diagnosis

Transformer as a commonly used equipment in the power system, its safety performance and work performance a significant role in the system.However, as the transformer operation will appear all sorts of failure for a long time, so we need to constantly test of transformer to judge the existence of abnormal and failure, usually judge the transformer fault types with electrical test and chemical test, electrical test methods alone it is often difficult to find some defects partial failure and fever, and through the gas in transformer oil chromatographic analysis of the chemical detection method, to find some transformer internal latent fault and its development level of early diagnosis is very sensitive and effective.This paper, from the perspective of the transformer fault types and principles of gas, to analyze and judge the fault, the principle of using chromatography was analyzed, and how to use the gas phase chromatography to judge transformer faults are expounded, and presents some practical use chromatography to judge transformer faults, thus to ensure the safe and stable operation of the grid system.
