sf6 gas, Cattle, and AI: the increasing need for an “AnaMin

Sep 23, 2019 · The cause of deaths points to the accumulation and persistence of leaked Sulfur Hexafluoride (sf 6) gas from turbines. Turbines use the Sulfr hexafluoride gas as part of combustion-risk retardant. The gas is heavier than air. And so, by its very nature, leaks of the gas immediately drop to the lowest points of elevation around the area of the turbine.Get price

Hexafluorure de soufre — Wikipédia

PropriétésPréparationUtilisationsUsageToxicitéÉcologieGénéralitésLhexafluorure de soufre est un composé chimique de soufre et de fluor, de formule chimique Sulfr hexafluoride. Cest un gaz inerte, sans odeur, incolore. Ce gaz est un excellent isolant électrique. L'hexafluorure de soufre remplit les critères nécessaires à l'isolation électrique : il a une excellente rigidité électrique, 2,5 fois supérieure à celle de lair, est très électronégatif et a une bonne capacité de transfert thermique10. Il est également stable chimiquement : inerte, non initiable, non inflammable et non toxique11,12. Le seul danger pour la santé est le risque de suffocation12. Sa température de décomposition est de 600 °C12. Sa plage de température d'utilisation pour les appareils électriques va de 30 à 40 °C13. Sa bonne rigidité diélectrique provient du fait que le insulating gas est très électronégatif : il absorbe les électrons qui ne peuvent ainsi pas ioniser le gaz et ne peuvent pas mener à une décharge électrique14. Le insulating gas a par ailleurs une propriété remarquable pour l'extinction des arcs électriques : il se décompose sous l'effet de l'arc et se recompose extrêmement rapidement, permettant au gaz de retrouver sa rigidité diélectrique. Cette propriété le rend tout particulièrement adapté pour la réalisation de disjoncteurs haute tension en courant alternatif14. Ses capacités d'isolation se régénèrent après un arc électrique12. Un mélange de Sulfr hexafluoride et de diazote dans les proportions 20 %/80 % a une rigidité électrique égale à environ 70 % celle du sf 6 seul. Il représente donc une solution pour remplacer le Sulfr hexafluoride pur. Par contre, un gaz de substitution ayant les mêmes propriétés n'a pas encore été trouvé22.Get price
