Evaluation of the Feasibility of Replacing SF6 With C5F10O for Gas-Insulated Switchgear From Insulation Properties

Abstract

Perfluoropentanone (C₅F₁₀O) gas mixtures are expected to be used in gas-insulated switchgear due to their excellent environmental and insulating properties. Nevertheless, the study of the insulating properties and influencing factors of C₅F₁₀O gas mixtures under the internal conditions of gas-insulated switchgear is not yet comprehensive. This paper comprehensively investigates the insulating properties of C₅F₁₀O/dry air gas mixtures. The findings demonstrate that adding C₅F₁₀O significantly enhances the insulating properties of the gas mixture. The findings of this research serve as a valuable reference for the engineering application, operation, and maintenance of C₅F₁₀O/dry air gas mixtures.
