Abstract

L’invention concerne un mécanisme (100) de commande pour l’ouverture et la fermeture de dispositif de coupure de courant. En particulier, le mécanisme comprend deux ressorts qui sont destinés à mettre en rotation, respectivement, une roue de fermeture et d’ouverture lorsqu’ils se relâchent à partir d’un état de compression. Le mécanisme implique donc l’armement des deux ressorts lors d’une phase d’armement via un levier d’armement, qui se désengage automatiquement lors d’une phase de fermeture exécutée par une mise en rotation de la roue de fermeture, et avec la seule énergie mécanique accumulée par le ressort couplé à ladite roue. Figure pour l’abrégé : figure 8.The invention relates to a control mechanism (100) for opening and closing a power cut-off device. In particular, the mechanism comprises two springs which are intended to rotate, respectively, a closing and opening wheel when they release from a state of compression. The mechanism therefore involves the arming of the two springs during an arming phase via an arming lever, which automatically disengages during a closing phase performed by rotating the closing wheel, and with the only mechanical energy accumulated by the spring coupled to said wheel. Figure for the abstract: Figure 8.
