| Abstract: | In order to effectively diagnose interior operation of SF6 electrical equipment, the paper introduces a new detection method for fault gas of SF6 electric equipment. The method uses PDHI chromatography and the primary sample injection can detect such components as SF6,O2, N2, H2S,SO2, SOF2,S02F2, S2OF10, CF4, C3F8, CO2 and CO, overcoming the inaccuracy, nonlinear response and insufficiency of components; it is a more promising fault gas detection method of SF, electric equipment. |
