CA 2511645

Improved switchgear is disclosed that includes a bus bar system that can be assembled from modular parts. The bus bar system includes modules such as high- voltage cables, connectors coupled to the cables and a third cable-less bus bar that is assembled using mechanical and/or push-on connections. By using these types of bus bars, various configurations, orientations of phase planes, and sizes of bus bar systems may be assembled. The connectors and cable-less bus bar may include either push-on. connection points, mechanical connections points or a combination of both. The bus bars may themselves include insulation and semiconductive shields. The improved switchgear may also include solid insulation, such as EPDM rubber, to insulate the bus bar system from the exterior surfaces of the switchgear.

La présente invention a trait à un appareil de commutation amélioré comportant un système de barre omnibus pouvant être assemblé à partir de pièces modulaires. Le système de barre omnibus comporte des modules, tels que des câbles haute tension, des connecteurs reliés aux câbles et une troisième barre omnibus sans câble qui est assemblée au moyen de connexions mécaniques et/ou à simple pression. Grâce à l'utilisation de ces types de barres omnibus, il est possible d'assembler diverses configurations, d'orientations de plan de phases, et de dimensions de systèmes de barre omnibus. Les connecteurs et la barre omnibus sans câble peuvent comporter soit des points de connexion à pression, des points de connexion mécaniques soit une combinaison des deux. Les barres omnibus peuvent elles-mêmes comporter des écrans d'isolation et semi-conducteurs. L'appareil de commutation amélioré peut également inclure un isolant solide, tel que du caoutchouc ethylène-propylène-diène, pour l'isolation du système de barre de bus des surfaces extérieures de l'appareil de commutation.
