Title (EN) VACUUM CIRCUIT BREAKER WITH IMPROVED CONFIGURATION
(FR) DISJONCTEUR À VIDE À CONFIGURATION AMÉLIORÉE
Abstract:
(EN) A vacuum circuit breaker comprising a vacuum interrupter (12) coupled between upper (18) and lower (20) terminals and being operable to make or break an electrical connection between the upper and lower terminals. The circuit breaker has a body 22 formed from electrically insulating material, the vacuum interrupter being located in an internal chamber of the body. The circuit breaker body is arranged to provide an isosceles triangle between the upper (C) and lower (A) terminal connection interfaces. This allows the same design of both upper and lower external connectors 80, 82. A pulling rod (16) coupled to the vacuum interrupter comprises a core (70) of heat-resistant plastic co-moulded with a shell (72) formed from impact resistant plastic.
(FR) L'invention concerne un disjoncteur à vide comprenant un interrupteur à vide (12) couplé entre des bornes supérieure (18) et inférieure (20) et pouvant fonctionner pour faire ou interrompre une connexion électrique entre les bornes supérieure et inférieure. Le disjoncteur possède un corps 22 formé à partir d'un matériau électroisolant, l'interrupteur à vide étant situé dans une chambre interne du corps. Le corps de disjoncteur est agencé pour fournir un triangle isocèle entre les interfaces de connexion de borne supérieure (C) et inférieure (A). Ceci permet la même conception des connecteurs externes supérieur et inférieur 80, 82. Une tige de traction (16) couplée à l'interrupteur à vide comprend un noyau (70) de plastique résistant à la chaleur co-moulé avec une coque (72) formée à partir de plastique résistant aux chocs.
