Abstract

La présente invention concerne un appareillage de commutation métallique de type fermé présentant deux lignes d'alimentation empilées dans un boîtier ayant la même dimension qu'un boîtier classique, et ayant des moyens de commande formés séparément au niveau de chaque disjoncteur et incorporés dans un compartiment séparé, de façon à permettre à un circuit de commande d'être entretenu et réparé dans un état où un circuit haute tension est un fil sous tension. En outre, la présente invention concerne un appareillage de commutation métallique de type fermé qui permet à des passages de décompression d'être séparément fournis à des espaces de disjoncteur supérieur et inférieur, un espace de barre omnibus, et des espaces de câbles supérieur et inférieur, de façon à empêcher des effets résiduels d'un accident d'être transférés à une carte de distribution voisine et ainsi permettre la réduction des coûts de maintenance et des coûts de fabrication.
