Comment Scientifiquement lutter contre la Corrosion de jet de Sel de l'\u00c9olien en mer des Transformateurs de Puissance?<\/b><\/h1>\n

\u2014L'Analyse en Profondeur des techniques de Protection et des Normes Internationales<\/b><\/h4>\n

Le mondial de l'\u00e9olien offshore capacit\u00e9 devrait d\u00e9passer les 380GW d'ici \u00e0 2030. Cependant, dans des environnements marins, le taux d'\u00e9chec des transformateurs en raison de la corrosion de jet de sel est de 3 \u00e0 5 fois plus \u00e9lev\u00e9 qu'\u00e0 terre de l'\u00e9quipement. Les ions chlorure (Cl\u207b) dans les embruns sal\u00e9s combinent avec l'humidit\u00e9 pour former un \u00e9lectrolyte, le d\u00e9clenchement de la corrosion \u00e9lectrochimique des cycles dans les m\u00e9taux. Ce n'est pas seulement causes annuel de g\u00e9n\u00e9ration d'\u00e9nergie perte de 0,8% \u00e0 1,5%, mais pose \u00e9galement des risques importants pour la s\u00e9curit\u00e9. Cet article propose une analyse syst\u00e9matique de jet de sel de la corrosion des solutions de protection, align\u00e9e avec les trois principales normes internationales: CEI, de l'ISO et de l'IEEE.<\/p>\n

Jet de sel \u00e9lectrochimique de la corrosion est un ph\u00e9nom\u00e8ne caus\u00e9 par le chlorure de sodium (NaCl) des particules transport\u00e9es par les vents de la mer et de l'humidit\u00e9. Son impact sur les transformateurs comprend:<\/p>\n

(1)Les Composants M\u00e9talliques De La Corrosion:<\/strong><\/h6>\n

Transformateur de bo\u00eetiers, les dissipateurs de chaleur, les attaches, et d'autres pi\u00e8ces m\u00e9talliques sont sujettes \u00e0 l'oxydation, la corrosion par piq\u00fbres et \u00e0 la corrosion caverneuse en brouillard salin environnements, conduisant \u00e0 une diminution de la r\u00e9sistance m\u00e9canique et le potentiel de risques de fuites.<\/p>\n
