Dans cette m\u00e9thode, l'air chaud ayant une temp\u00e9rature allant de 105 \u00e0 130\u00b0C est introduit dans une cuve sous vide pour chauffer l'appareil, s'assurer un chauffage uniforme de son int\u00e9rieur et \u00e9lever la temp\u00e9rature pour atteindre l'\u00e9vaporation de l'humidit\u00e9.<\/p>\n<p>Pour la grande capacit\u00e9 des transformateurs, le chauffage et l'extraction sous vide doivent \u00eatre altern\u00e9es. Par exemple, au d\u00e9part, 40 heures de chauffage \u00e0 air chaud est suivi par 10 \u00e0 15 heures de l'extraction sous vide; puis, de 10 \u00e0 20 heures de chauffage est remplac\u00e9 par un autre 10 \u00e0 15 heures de l'extraction sous vide. Le nombre de cycles d\u00e9pend du niveau de tension, avec une augmentation des niveaux de tension n\u00e9cessitant plus de cycles. Cela est d\u00fb \u00e0 l'augmentation du nombre de composants d'isolement et de fil plus \u00e9pais regroupement dans l'ultra-haute tension transformateurs, r\u00e9sultant en un petit passage d'huile d'habilitations.<\/p>\n<p>Lorsque la temp\u00e9rature interne atteint un certain niveau, une quantit\u00e9 importante d'humidit\u00e9 s'\u00e9vapore, ce qui entra\u00eene une hausse de l'humidit\u00e9 dans l'huile d'\u00e9cart. Continue \u00e0 introduire de l'air chaud devient difficile, provoquant une chute dans l'isolation de la temp\u00e9rature minimale et de l'efficacit\u00e9 de la circulation d'air chaud de chauffage. Dans ces circonstances, l'ex\u00e9cution de l'extraction sous vide r\u00e9duit la pression, conduisant \u00e0 une \u00e9vaporation rapide de l'humidit\u00e9 dans l'isolation des composants et de l'huile de lacunes. Ceci, \u00e0 son tour, diminue la vapeur d'eau de la concentration dans l'isolation. Apr\u00e8s avoir atteint un certain niveau, la reprise de chauffage \u00e0 air chaud permet de maintenir une temp\u00e9rature mod\u00e9r\u00e9e de chute \u00e0 l'int\u00e9rieur du transformateur, qui r\u00e9cup\u00e8re rapidement. Ce proc\u00e9d\u00e9 permet d'obtenir efficace de s\u00e9chage.<\/p>\n<p>Le sch\u00e9ma de principe du vide pipeline syst\u00e8me est illustr\u00e9 \u00e0 la Figure 41-1. En raison de la forte aspiration requise (10-133Pa) pour le r\u00e9servoir vide, deux \u00e9tapes de la pompe \u00e0 vide doit \u00eatre \u00e9quip\u00e9 dans le vide pipeline. Cela garantit le niveau de vide souhait\u00e9 est atteint, tout en minimisant le temps n\u00e9cessaire pour l'extraction sous vide. En r\u00e8gle g\u00e9n\u00e9rale, un H-9 vanne de la pompe \u00e0 vide est adapt\u00e9 pour la pompe primaire, et un ZJ-1200 m\u00e9canique d'appoint de la pompe est recommand\u00e9e pour le secondaire de la pompe. Pour garantir l'\u00e9tanch\u00e9it\u00e9 de l'ensemble vide syst\u00e8me de pipeline, les diverses caract\u00e9ristiques de haute soupapes de d\u00e9pression (comme la GI et de la GIQ types) doit \u00eatre s\u00e9lectionn\u00e9. Pour emp\u00eacher l'humidit\u00e9 de l'air de p\u00e9n\u00e9trer dans la pompe \u00e0 vide et de la condensation dans l'eau, un condensateur est sp\u00e9cialement con\u00e7us, et de l'eau-de s\u00e9parateurs d'huile sont plac\u00e9s avant et apr\u00e8s la pompe lors de l'extraction sous vide.<\/p>\n<p>Pour s'assurer que l'air chaud introduit dans le r\u00e9servoir est propre, un filtre \u00e0 air doit \u00eatre install\u00e9 \u00e0 l'avant de la pompe.<\/p>\n<h2 style=\"font-weight: bold;\">Contact<\/h2>\n<p>LuShan, heure de l'est. 1975, est un fabricant professionnel Chinois sp\u00e9cialis\u00e9 dans les transformateurs de puissance et des r\u00e9acteurs de plus de 50 ans.
