Abstract

La présente invention a pour objet une chambre de détente (1) d'arc électrique pour appareillage de coupure électrique de type disjoncteur électrique à boîtier en matériau isolant moulé, ladite chambre de détente (1) étant délimitée transversalement par des parois latérales (3) dudit boîtier et contenant un système de contacts mobiles (4, 5) séparables, caractérisée en ce que la chambre de détente (1) d'arc comprend une paire de joues isolantes (7, 7') rapportées dont au moins une partie de leurs extrémités (8, 8') forment, au moins au niveau desdits contacts mobiles (4, 5) assemblés et avec lesdites parois latérales (3) dudit boîtier, des poches (9) latérales destinées à recueillir et à immobiliser les particules de matières polluantes générées lors de la formation de l'arc électrique. Elle a également pour objet un disjoncteur équipé d'une telle chambre de détente (1).The subject of the present invention is an arc flash chamber (1) for electrical switchgear apparatus of the electric circuit-breaker type with a casing of molded insulating material, said expansion chamber (1) being delimited transversely by lateral walls (3). of said housing and containing a system of separable movable contacts (4, 5), characterized in that the arc expansion chamber (1) comprises a pair of insulating flanges (7, 7 '), of which at least a portion of their ends (8, 8 ') form, at least at the level of said assembled movable contacts (4, 5) and with said lateral walls (3) of said housing, lateral pockets (9) intended to collect and immobilize the particles of pollutants generated during the formation of the electric arc. It also relates to a circuit breaker equipped with such a relaxation chamber (1).
