摘要

二氧化碳和 C5F10O 的混合气体作为 SF6 的替代气体之一已被广泛研究。由于氧分子 O2 具有更好的电子附着能力，人们普遍认为加入 O2 气体可提高熄弧和电力设备绝缘气体的介电强度。因此，本文对热 CO2/O2/C5F10O 混合气体的介电击穿特性进行了数值估算。计算结果表明，CO2/C5F10O 混合气体的临界电场强度会随着 O2 气体的加入而降低，尤其是在 3000 K 至 1000 K 的温度范围内。© 2024 日本电气工程师学会和 Wiley Periodicals LLC。

A Study on Dielectric Breakdown Properties of Hot CO2/O2/C5F10O Gas Mixture: Focus on Concentration Rate of O2 Gas

A gaseous mixture of CO₂ and C₅F₁₀O has been widely investigated as one of the alternative gases for SF₆. Due to the better electron attachment ability of oxygen molecule O₂, it is generally expected that adding of O₂ gas would improve the dielectric strength of arc quenching and insulating gas for electric power equipment. Therefore, in this paper, the dielectric breakdown properties of hot CO₂/O₂/C₅F₁₀O gas mixture were numerically estimated. The calculation results revealed that the critical electric field strength of the CO₂/C₅F₁₀O gas mixture is disappointingly decreased by the addition of O₂ gas, especially in the temperature range of 3000 K to 1000 K. This is brought about by the increase of ionization reaction of CO₂ molecules with an increase in the O₂ concentration in the arc-quenching gas of CO₂/O₂/C₅F₁₀O. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
