Abstract: 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.
Key words: high altitude; medium voltage gas insulated metal enclosed switchgear; enhanced design; capacity reduction; selection and application
