Title (EN) ELECTRIC SWITCH PROVIDED WITH AN ARC-BLASTING UNIT
(FR) INTERRUPTEUR ÉLECTRIQUE COMPRENANT UNE UNITÉ DE SOUFFLAGE D'ARC
Abstract:
(EN) This electric switch comprises an arc-blasting unit with a compression cylinder (25) enclosing a compression chamber (27) mobile together with the mobile contacts (2), and a stationary piston (13) at an end of the compression chamber, provided with a support rod made up as a blowpipe (9) which channels the gas compressed in the chamber when the contacts separate to a nozzle (10) that directs the flow to a separation place (12) of the contacts so as to efficiently blast electric arcs. The arrangement is lightweight and occupies little space.
(FR) L'invention concerne un commutateur électrique comprenant une unité de soufflage d'arc avec un cylindre de compression (25) renfermant une chambre de compression (27) mobile avec les contacts mobiles (2), et un piston stationnaire (13) à une extrémité de la chambre de compression, comprenant une tige de support constituée sous la forme d'un tuyau de soufflage (9) qui canalise le gaz comprimé dans la chambre lorsque les contacts se séparent d'une buse (10) qui dirige l'écoulement vers un emplacement de séparation (12) des contacts de façon à souffler efficacement des arcs électriques. L'agencement est léger et occupe peu d'espace.
