Abstract

Dans les transformateurs, des gaz peuvent se former par surchauffe de l'huile isolante. Le changeur de prises en charge est monté dans un boîtier (9) composé d'un couvercle (9D), d'un fond (9B) et d'une enveloppe (9M) et le boîtier fait saillie dans la cuve (7) de transformateur et est rempli de liquide isolant (6). Le changeur de prises en charge est entouré de liquide isolant (6) et le couvercle du boîtier comprend au moins une région (20) perméable au gaz par laquelle le gaz peut s'échapper de l'intérieur du changeur de prises en charge. Le fond et/ou l'enveloppe du boîtier peuvent être conçus avec des ouvertures (10) par lesquelles une communication fluidique est fournie entre le liquide isolant dans la cuve (7) du transformateur et le liquide isolant dans le boîtier (9). Un composant électronique au moyen duquel la capacité de fonctionnement de la région perméable au gaz peut être surveillée peut être intégré dans la région (20) perméable au gaz.
