Patent

CA 2242096

The invention concerns an open air high-voltage circuit breaker comprising a circuit breaker unit (13) and a control capacitor connected electrically in parallel to it and surrounded by a common composite isolation housing (7, 8) made essentially of plastic, resting a terminal column (1) fixed to one of its ends. The use of a composite isolation housing saves cost and weight at the upper end of the terminal column and also improves earthquake security.

Disjoncteur haute tension pour l'extérieur, comprenant une unité d'interruption (13) et un condensateur de commande, monté électriquement en parallèle par rapport à celle-ci et entouré par une carcasse d'isolateur composite (7, 8) essentiellement en matière plastique, prenant appui de manière fixe, par l'une de ses extrémités, sur une colonne polaire (1). L'utilisation d'une carcasse d'isolateur composite permet une économie en termes de coût et de poids, à l'extrémité supérieure de la colonne polaire, tout en améliorant en même temps la sécurité sismique.
