Title (EN) KINEMATIC SYSTEM FOR ACTUATING THE MOVABLE CONTACT OF AUTOMATIC ELECTRIC BREAKERS
(FR) SYSTEME CINEMATIQUE PERMETTANT D'ACTIONNER LE CONTACT MOBILE DE DISJONCTEURS ELECTRIQUES AUTOMATIQUES
Abstract:
(EN) A kinematic system for actuating the movable contact of automatic electric breakers includes an actuation mechanism (5) which includes an external handle (9) which is pivoted to the body (3) of a breaker and is connected to the cross-member (13), which is in turn connected to an actuation lever (15) which is operatively associated with a reset spring (17) and with an actuation spring (19), both of which are coupled to a common pivot (21); a mushroom-shaped member (23) of a relay of the breaker acts on a reset lever (25) which is in turn kinematically associated with a hook (27) supported by a second common pivot (29); an engagement lever (31), retained by the hook, is suitable to act on the rear part of a traction lever (33).
(FR) L'invention concerne un système cinématique permettant d'actionner le contact mobile de disjoncteurs électriques automatiques, ledit système comprenant un mécanisme (5) d'actionnement comprenant une poignée externe (9) qui pivote sur le corps (3) du disjoncteur et est reliée à la traverse (13), qui est à son tour reliée à un levier (15) d'actionnement associé de manière opérationnelle à un ressort (17) de rétablissement et à un ressort (19) d'actionnement, tous deux accouplés à un pivot (21) commun; un élément (23) en forme de champignon d'un relais du disjoncteur agit sur un levier (25) de rétablissement, qui est à son tour associé de manière cinématique à un crochet (27) supporté par un second pivot (29) commun; un levier (31) de prise, retenu par le crochet, est adapté pour agir sur la partie arrière d'un levier (33) de traction.
