Abstract

La présente invention réduit une surface pour installer un appareillage de connexion isolé par gaz utilisé en tant qu'équipement de réception de puissance. Cet appareillage de connexion isolé par un gaz est construit par installation de multiples panneaux (1) côte-à-côte sur une ligne, chacun desdits panneaux ayant les fonctions d'un panneau entrant (R), d'un panneau de transformateur (F) et d'un VCT (V). L'appareillage de connexion comporte des barres omnibus triphasées horizontales (12-15), qui sont utilisées pour connecter les panneaux (1) ensemble, pour un maximum de quatre circuits. L'espace pour installer l'équivalent des quatre circuits de barres omnibus triphasées horizontales (12-15) est divisé en deux rangées dans la direction avant-arrière et deux étages dans la direction verticale dans la section supérieure ou la section inférieure d'un boîtier pour les panneaux (1) afin de loger le maximum des quatre circuits, et les barres omnibus triphasées horizontales (12-15) pour connecter les panneaux (1) ensemble sont agencées de telle sorte que les conducteurs de phases respectives soient positionnés horizontalement dans la direction avant-arrière des panneaux (1) à des intervalles prédéterminés. Les barres omnibus triphasées horizontales (12-15) comportent des bagues (18-21) sur les deux extrémités et agencées pour s'étendre à travers l'espace d'installation, lesdites bagues pénétrant à travers un réservoir de connexion de barres omnibus (8) à partir du dessus ou de dessous du réservoir de connexion des barres omnibus (8).
