Influence of Oxygen on the Thermal Decomposition Properties of C₄F₇N-N₂-O₂ as an Eco-Friendly Gas Insulating Medium.

ABSTRACT: The C₄F₇N (fluorinated nitrile) gas mixture has been recognized as the most potential substitute gas to SF₆ used in gas-insulated equipment. In this paper, we explored the thermal stability and decomposition properties of the C₄F₇N-N₂-O₂ gas mixture. The influence mechanism of oxygen content and temperature on the byproduct generation was obtained and analyzed. It was found that thermal decomposition of the C₄F₇N-N₂-O₂ gas mixture mainly produces CO, C₃F₆, C₃F₈, CF₃CN, (CN)₂, and COF₂. The addition of oxygen could accelerate the decomposition of C₄F₇N. The content of C
