Abstract

La présente invention concerne un mécanisme d'actionnement du contact mobile d'une chambre de coupure (1) de protection installée sur une ligne électrique haute ou moyenne tension et devant être ouverte à l'apparition d'un seuil de surintensité sur la ligne, ce mécanisme comportant un organe moteur entraînant un dispositif de déplacement (5) du contact. L'organe moteur est un ressort hélicoïdal (6) conducteur en alliage à mémoire de forme lié
électriquement à la ligne et dont l'échauffement, lorsqu'il est traversé par ledit seuil de surintensité, est tel que ledit alliage passe de sa phase martensitique à sa phase austénitique et il permet la refermeture de la chambre de coupure (1) grâce à un dispositif séquenceur (8) associé au dispositif de déplacement (5) et assurant un cycle réglable et temporisé d'ouvertures et de fermetures.
