摘要:
使用SF6/N2混合氣體代替純SF6氣體作爲GIS母線氣室的絕緣介質,是一種大幅降低SF6氣體使用量的新型技術。文中對該混合氣體的溫度和壓力特性開展了研究,利用道爾頓分壓定律、貝蒂—布裏奇曼方程、理想氣體狀態方程對SF6/N2混合氣體狀態方程進行了推導,開展了混合氣體溫度壓力試驗,對SF6占體積比30%±2%的SF6/N2混合氣體的試驗測量數據和理論計算數據進行了對比分析,確定了該方程在工程應用上的有效性。根據研究繪制了混合氣體溫度壓力特性曲線,爲相關GIS設備以及氣體監測儀表儀器的設計研發提供了依據。
Abstract:
It is a new technology to significantly reduce the use of SF6 gas that using SF6 /N2 gas mixtures as the insulating medium of GIS bus air chamber instead of pure SF6 gas. In this paper, the temperature and pressure characteristics of the gas mixtures are studied. The state equation of SF6 /N2 gas mixtures is derived by using Dalton’s law, Beattie?Bridgeman equation and ideal gas equation. The temperature and pressure test is done. The measured data and theoretical calculation data are compared while the volume ratio of SF6 is 30%±2% in the SF6 /N2 gas mixtures, and the validity of the equation in engineering applications is determined. According to the study, the temperature and pressure characteristic curves of the gas mixtures are plotted, which provides the basis for the design and development of the relevant GIS equipment and gas monitoring instruments.
