Title
(EN) A SWITCHGEAR EQUIPMENT WITH A SHUTTER ASSEMBLY
(FR) ÉQUIPEMENT DE COMMUTATION DOTÉ D'UN ENSEMBLE OBTURATEUR
Abstract
(EN)
A switchgear equipment having a bus bar connection with a vacuum circuit breaker (V CB) through a bushing having an opening to receive a terminal of the VCB for electrical connection with a current collector that is partially embedded within the bushing, the opening of the bushing gets covered with a shutter plate of a shutter assembly, and the shutter assembly comprises an operating link associated with a frame of the VCB to operate the shutter plate on movement of the VCB; the current collector comprises a first metallic portion for receiving the terminal of the VCB and a second metallic portion perpendicular to the first metallic portion. The second metallic portion having surface area larger than the surface area of the first metallic portion for reducing non- uniform electric field between the current collector and shutter plate when the shutter plate is closing the opening of the bushing.
(FR)
La présente invention concerne un équipement de commutation ayant une connexion de barre omnibus avec un disjoncteur sous vide (VCB) à travers une douille ayant une ouverture pour recevoir une borne du VCB pour une connexion électrique avec un collecteur de courant qui est partiellement intégré à l'intérieur de la douille, l'ouverture de la douille étant recouverte d'une plaque d'obturateur d'un ensemble obturateur, et l'ensemble obturateur comprenant une liaison de fonctionnement associée à un cadre du VCB pour faire fonctionner la plaque d'obturateur lors du mouvement du VCB; le collecteur de courant comprend une première partie métallique pour recevoir la borne du VCB et une seconde partie métallique perpendiculaire à la première partie métallique. La seconde partie métallique a une surface supérieure à la surface de la première partie métallique pour réduire le champ électrique non uniforme entre le collecteur de courant et la plaque d'obturateur lorsque la plaque d'obturateur ferme l'ouverture de la douille.
