Gas-insulated substation (GIS) yog ib qho hluav taws xob hluav taws xob uas muaj cov khoom siv loj uas muaj nyob rau hauv ib puag ncig kaw nrog cov roj dielectric hu ua SF6, lossis sulfur hexafluoride gas ua qhov nruab nrab insulating. Nyob rau hauv kev sib piv, ib tug pa (AIS) los yog Cua-Insulated Substation, siv atmospheric huab cua raws li dielectric gas nruab nrab, raws li cov hom ntawm substations feem ntau muaj nyob rau sab nraum zoov.
Gas insulated substation (GIS) muaj cov khoom siv uas cov khoom siv hluav taws xob muaj peev xwm nyob hauv nruab nrab ntawm cov kav dej aluminium alloy thiab tuav hauv qhov chaw no los ntawm epoxide resin insulators. Cov kav dej tau sau nrog cov roj insulating thiab muaj lub peev xwm hauv ntiaj teb. GIS muaj xws li HV cov khoom xws li disconnectors, CBs, busbars, thiab voltage thiab tam sim no transducers. GIS tuaj yeem txuag tau txog li 90% ntawm qhov chaw piv nrog cov cua-insulated substations. Nws yog tshwj xeeb tshaj yog haum rau kev siv sab hauv tsev thiab sab nraum zoov.
