Title (EN) HIGH SPEED ACTUATING MECHANISM
(FR) MECANISME A ACTION RAPIDE
Abstract: front page image
(EN)A high speed actuating mechanism for operating the contacts of a circuit interrupter has an operating shaft (73) connected to the contacts and to an operating piston (90). The operating piston (90) has a short-circuited conductive ring or repulsion disc (160) which is closely coupled to a lenz coil operator (151) in one position of the actuating mechanism. The operating piston (90) also has an enlarged diameter sealing protrusion (92) which seals against an annular seal (130) which is concentric with the lenz coil operator (151). Both the lenz coil (151) and the sealing ring (130) are spring-mounted to have several degrees of resiliency to enable proper relative location of the repulsion disc (160) and the lenz coil (151) and proper relative location of the annular seal (130) and contact protrusion (92) to control seal penetration and to enable compensation for contact erosion when butt-type contacts are used.
(FR)Une mecanisme a action rapide de fonctionnement des contacts d"un disjoncteur de circuit possede un arbre de fonctionnement (73) relie aux contacts et a un piston de fonctionnement (70). Le piston de fonctionnement (70) possede un anneau conducteur court-circuite ou disque de repulsion (160) qui est couple a un operateur a bobine d"induction (151) dans une position du mecanisme d"actionnement. Le piston de fonctionnement (90) possede egalement une protuberance d"etancheite de diametre elargi (92) qui appuie sur un anneau d"etancheite (130) concentrique a l"operateur a bobine d"induction (151), La bobine d"induction (151) et l"anneau d"etancheite (130) sont montes sur un ressort pour avoir plusieurs degres d"elasticite et permettre une bonne position relative du disque de repulsion (160) et de la bobine d"induction (151) ainsi qu"une bonne position relative de l"anneau d"etancheite (130) et de la protuberance de contact (92) pour commander la penetration du joint et permettre de rattraper l"usure par contact lorsqu"on utilise des contacts du type a pointe.
