Gas Chromatography-based Detection Technology of Decomposition Products of SF6 Electrical Equipment
Detecting SF6 gas decomposition products is the main means to determine the operational status of SF6 electrical equipment.In this paper,advantages and disadvantages of different detection methods for SF6 decomposition products are summarized,and the current status of SF6 electrical equipment decomposition product detection technology based on gas chromatography is analyzed.With respect to the problem of insufficient detection sensitivity of SF6 electrical equipment decomposition products based on gas chromatography,methodologies of improving detection sensitivity is proposed.
