Gaseous rwb thaiv tsev cov ntaub ntawv
- Huab cua: Tus nqi qis heev nrog cov khoom siv hluav taws xob ruaj khov; dav siv rau rwb thaiv tsev qhov sib txawv nyob rau hauv overhead kis kab thiab cov pa switchgear.
- Sulfur Hexafluoride (SF₆): Muaj lub zog rwb thaiv tsev 2-3 npaug ntawm huab cua thiab muaj peev xwm tua tau arc-; Feem ntau siv hauv high-voltage gas-insulated switchgear (GIS), gas-insulated transformers, thiab cov cuab yeej zoo sib xws.
- Lwm cov pa roj: Nitrogen, sulfur dioxide, thiab lwm yam.; siv nyob rau hauv tshwj xeeb kaw cov khoom siv hluav taws xob los muab rwb thaiv tsev thiab tiv thaiv oxidation.
Cov khoom siv hluav taws xob ua kua
- Mineral Insulating Roj: Ua piv txwv los ntawm cov roj transformer; muaj cov rwb thaiv tsev zoo tshaj plaws thiab cov khoom cua kub dissipation, ua tus thawj rwb thaiv tsev thiab cua txias nruab nrab rau transformers, fais fab cables, thiab capacitors.
- Synthetic Insulating Oil: Xws li cov roj silicone; characterized los ntawm cov tshuaj lom neeg ruaj khov thiab kev ua haujlwm kub ntau, ua rau nws tsim nyog rau cov khoom siv hluav taws xob tshwj xeeb nrog kev xav tau kev ua haujlwm.
- Ntuj Zaub Roj: xws li roj castor; environmentally friendly thiab biodegradable, nce siv nyob rau hauv eco-phooj ywg transformers.
