摘要
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 SFs 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.关键词
