摘要
分析了SF6和N2气体的状态参量关系,按照GIS母线工程应用和高精度计算要求分别给出了SF6-N2混合气体分压状态方程和SRK状态方程,研究了SF6-N2混合气体液化和高落差时混合均匀性的情况,提供了一种工程应用的SF6-N2混合气体饱和蒸汽压拟合公式,说明了GIS设备应用SF6-N2混合气体时是否存在气体分层的问题.
The state parameters of SF 6 gas and N 2 gas are analyzed,and the states equations for split pressure and SRK of SF 6一N 2 gas mixtures are given according to engineering application and high precision calculation for busbar.In this paper,the liquefaction and mixing uniformity at high drop difference of SF 6一N 2 gas mixtures are studied,the formula for fitting the saturated vapour pressure of SF 6一N 2 gas mixtures for engineering applications is provided and the gas stratification in GIS equipment using SF 6一N 2 gas mixtures is explained.
