Abstract

Cet appareil comporte un premier circuit dit principal P comportant un sectionneur (2), et un second circuit dit de dérivation D monté en parallèle par rapport au premier, ce second circuit D comportant une ampoule à vide A destinée à assurer la coupure du courant, ledit circuit de dérivation étant inactif en régime permanent, et parcouru par l'électricité seulement quand le sectionneur a commencé son mouvement d'ouverture, par un transfert progressif du courant de la ligne principale à la ligne de dérivation, cet appareil comportant un ressort dit de pression de contact (10) et un ressort dit d'ouverture (11). Cet appareil est caractérisé en ce qu'il comporte un dispositif d'accrochage O dit premier apte à être activé par le mécanisme de commande du sectionneur (2) après une certaine course de celui-ci dans le sens de sa fermeture ayant entraîné la compression des ressorts de fermeture (10) et d'ouverture (11) précités, de manière à réaliser un maintien en position fermée des contacts de l'ampoule A en conservant l'effort de contact précité, ce dispositif étant apte à être désactivé par le mécanisme de commande du sectionneur (2) après une certaine course de celui-ci dans le sens de son ouverture de manière à permettre la décompression du ressort d'ouverture précité (10) et l'ouverture des contacts de l'ampoule A grâce à l'action combinée des deux ressorts (10,11) respectivement d'ouverture et de fermeture.This apparatus comprises a first so-called main circuit P comprising a disconnector (2), and a second so-called bypass circuit D connected in parallel with the first, this second circuit D comprising a vacuum interrupter A intended to ensure the current cut-off, said branch circuit being inactive in steady state, and traversed by electricity only when the disconnector has begun its opening movement, by a progressive transfer of the current from the main line to the branch line, this apparatus comprising a spring called contact pressure (10) and a so-called opening spring (11). This device is characterized in that it comprises a so-called first hooking device O capable of being activated by the control mechanism of the disconnector (2) after a certain stroke of the latter in the direction of its closing having caused the compression aforementioned closing (10) and opening (11) springs, so as to hold the contacts of bulb A in the closed position while maintaining the aforementioned contact force, this device being capable of being deactivated by the disconnector control mechanism (2) after a certain travel of the latter in the direction of its opening so as to allow the decompression of the aforementioned opening spring (10) and the opening of the contacts of the bulb A thanks to the combined action of the two springs (10,11) opening and closing respectively.
