Abstract (en)
The device has a disengageable transmission drive train (54) which can be moved between an engaged state and a disengaged state. Movement transmission between a bistable sub-arrangement (22) and a movable contact (10) is ensured when the drive train is in the engaged state, so that when the sub- arrangement is in the open position, the contact is in the separation position, whilst when the sub-arrangement is in the closed position, the contact is in the contact position. The contact becomes independent from the sub-arrangement when the drive train is in the disengaged state. The disconnection mechanism comprises a support (21), a contact which is movable relative to the support between separation and contact positions and a bistable sub-arrangement cooperating with a spring accumulator (20) so that the sub-arrangement is pivoted between open and closed positions. The spring is tensioned as the sub-arrangement approaches an intermediate dead point between its open and closed positions and then relaxes as it moves away from this dead point, causing the sub-arrangement to become spring-loaded.
Abstract (fr)
Le porte contact 10 d'un appareil électrique de coupure est relié à un sous-ensemble bistable 22 coopérant avec un ressort d'accumulation 20 par l'intermédiaire d'une chaîne cinématique de transmission débrayable 54, ce qui permet d'ouvrir l'appareil rapidement et avec une faible énergie sans avoir à déplacer le sous-ensemble bistable 22 de la position stable de fermeture à la position stable d'ouverture. Une fois la chaîne cinématique 54 débrayée, le ressort d'accumulation 20 et/ou un ressort additionnel 88 entraînent le porte contact 10 vers la position de séparation. Le système comporte un verrou de déclenchement 82 libérant le ressort utilisé dans la séquence de déclenchement, le mouvement du ressort permettant de déverrouiller un verrou de débrayage 80 de la chaîne cinématique débrayable. <IMAGE>
