252kV三相共箱GIS母线壳体温度场分布特性研究
Research on Temperature Field Distribution Characteristics of 252 kV Three-phase Enclosed GIS Bus Bar Shell
摘要
Abstract
Gas insulated switchgear (GIS) is widely used in power system,the overheating of the internal contact will cause serious accidents,therefore the study of its temperature field distribution is particularly important.In this paper,the 252 kV GIS temperature-rise test platform is designed,and the temperature field distribution characteristics of conductor,SF6 gas and the shell are obtained.Specific to the above-mentioned GIS platform,the three-dimensional physical model and mathematical model are established.The finite element analysis method is used to simulate the temperature field distribution.The results show that the temperature of SF6 gas in the top of the GIS shell is not quite different,while there are obvious differences of the SF6 gas temperature in the area below the GIS shell.The SF6 gas temperature close to the shell is approximately identical with the shell.For the shell,the temperature difference between the top and side is small.The temperature at the bottom is the lowest and the temperature gradually drops along the circumferential direction from the top to the bottom.The above research can provide certain directive significance for revealing the temperature field distribution and determining the most sensitive temperature perception position in the GIS bus bar shell.关键词
