Application of Medium Pressure Gas Insulated Metal Enclosed Switchgear in High Altitude Area

分析了中压气体绝缘金属封闭开关设备(GIS)在高海拔地区应用的优势和高海拔气候条件对中压GIS的影响。结合中压GIS的设计与制造经验,通过仿真和理论分析提出了高海拔地区中压GIS设备的设计要求。结果表明:中压气体绝缘金属封闭开关设备采用气室加强型设计、元器件材料合理选择、低压元器件降容使用、选择通过环境试验的元器件等多项措施后,可满足在高海拔环境的要求。

This paper analyzed the advantages of application of medium pressure gas insulated metal enclosed switchgear(GIS)in high altitude area and the influence of high altitude climate on the medium voltage GIS.Combining with the medium voltage GIS design and manufacture experience,via simulation and theoretical analysis,this paper proposed the design requirements of the medium voltage GIS in high altitude area.The results show that the medium voltage GIS adopted the design of gas chamber reinforcement design,rational selection of component materials,low voltage components reduction use and selection of components through environmental test so as to meet the requirements of high altitude environment.
