摘要

气体绝缘金属封闭开关（gas insulated switchgear

GIS）在电力系统中应用广泛

其内部触头过热会引发重大事故

因此研究其温度场分布特性具有重要意义。文中设计了252 kV GIS温升实验平台

通过实验获得了GIS母线导体、SF6气体和外壳部位的温度分布情况。针对上述实验平台建立了GIS三维物理模型和数学模型

基于有限元分析法对上述实验获得的GIS母线壳体温度场分布规律进行了仿真佐证。研究结果表明

在GIS壳体内部靠上区域

SF6气体温差较小

梯度不明显

而在GIS壳体内部下方区域

SF6气体温度呈明显的梯度分布;靠近壳体的SF6气体温度和壳体温度趋于一致;对于外壳

其顶部和侧面温差不大

底部温度最低

沿着圆周方向从顶部到底部温度逐渐降低。上述研究可为揭示GIS内部温度场分布特性和确定温度感知最灵敏位置提供一定的指导意义。

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

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 distr

ibution.The results show that the temperature of SF

gas in the top of the GIS shell is not quite different

while there are obvious differences of the SF

gas temperature in the area below the GIS shell.The SF

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.
