Title
(EN) SPLITTER PLATE, ARC EXTINGUISHING CHAMBER AND SWITCHING DEVICE
(FR) PLAQUE DE SÉPARATION, CHAMBRE D'EXTINCTION D'ARC ET DISPOSITIF DE COMMUTATION
Abstract
(EN)
A splitter plate (14) for an arc extinguishing chamber (12) in a switching device (10), the splitter plate (14) comprising a base portion (40); a pair of arms (30) extending from the base portion (40); a recess (34) for a movable contact (18) defined between the arms (30); and a slot (32) in each arm (30); wherein the recess (34) is arranged between the slots (32). An arc extinguishing chamber (12) for a switching device (10) is also provided. A switching device (10) for breaking an electric current, the switching device (10) comprising a plurality of splitter plates (14) or an arc extinguishing chamber (12) is also provided.
(FR)
L'invention concerne une plaque de séparation (14) destinée à une chambre d'extinction d'arc (12) dans un dispositif de commutation (10), la plaque de séparation (14) comprenant une partie de base (40) ; une paire de bras (30) s'étendant à partir de la partie de base (40) ; un évidement (34) pour un contact mobile (18) défini entre les bras (30) ; et une fente (32) dans chaque bras (30, l'évidement (34) étant disposé entre les fentes (32). L'invention concerne également une chambre d'extinction d'arc (12) destinée à un dispositif de commutation (10). L'invention porte en outre sur un dispositif de commutation (10) pour la coupure d'un courant électrique, le dispositif de commutation (10) comprenant une pluralité de plaques de séparation (14) ou une chambre d'extinction d'arc (12).
