摘要

SF₆ is currently the most widely used insulating gas, but the global warming potential of SF₆ gas is very high and not easy to degrade, the use of gas mixtures containing SF₆ such as SF₆/N₂ can effectively reduce the use of SF₆ and thus reduce the impact of the greenhouse effect. Therefore, this paper carries out the corona discharge decomposition test of SF₆/N₂ under different contents of micro water and micro oxygen, detects the products and analyzes the contents of the products by chromatography, and derives the influence of micro water and micro oxygen on the decomposition products according to the decomposition products under different micro water and micro oxygen to provide support for the identification of the GIS discharge faults with SF₆/N₂ as the insulating gas by chemical diagnosis method. The experimental results show that the volume fractions of SOF₂ and SO₂F₂ are obviously increased with the participation of micro-oxygen in water.
