Abstract

L'invention concerne une installation d'isolation électrique qui comporte un premier boîtier (1, 2, 3) et un second boîtier (12, 13, 14, 15). Le premier boîtier (1, 2, 3) ainsi que le second boîtier (12, 13, 4, 15) délimitent une chambre de fluide (10a, 10b, 10c) à l'intérieur de laquelle un fluide isolant électrique est disposé. Le second boîtier (12, 13, 14, 15) fait partie d'un dispositif de filtre qui est relié au premier boîtier (1, 2, 3) par un canal de fluide (11a, 11b, 11c, 11d).
