Title (EN) DIVERTER SWITCH AND LINK SYSTEM FOR LOAD TAP CHANGER
(FR) COMMUTATEUR ET SYSTEME D'ARTICULATION DESTINES A UN CHANGEUR DE PRISES
Abstract:
(EN) A load tap changer comprising in part a diverter switch is disclosed. The diverter switch includes a movable main contact (38), first and second fixed main contacts (40a, 40b), a pantograph system (30) for translating a rotational motion of a shaft (22) to a substantially linear motion of the movable main contact. The load tap changer further comprises a link system (10) comprising a gear adapted to be rotated by a motor, a spring battery for storing energy of the motor and a link assembly for coupling the gear to the spring battery. The shaft is coupled to the link assembly to enable the spring battery to rotate the shaft and effect movement of the movable main contact. A predetermined amount of rotation of the shaft effects a movement of the main contact from a contacting position with the first fixed main contact to a contacting position with the second fixed main contact.
(FR) Changeur de prises constitué pour une part d'un commutateur lui-même formé d'un contact principal mobile (38), d'un premier et d'un deuxième contact fixes principaux (40a, 40b), d'un système (30) de pantographe qui permet de transformer le mouvement rotatif d'un axe (22) en mouvement sensiblement linéaire du contact principal mobile. Le changeur de prises comprend un système (10) d'articulation comportant un engrenage conçu pour être mis en rotation par un moteur, un accumulateur à ressort (26) servant à stocker l'énergie du moteur et un ensemble d'articulation prévu pour coupler l'engrenage à l'accumulateur à ressort. L'axe est couplé à l'ensemble d'articulation pour permettre à l'accumulateur à ressort de faire tourner l'axe et de faire bouger le contact principal mobile. Un degré de rotation prédéterminé de l'axe entraîne un mouvement du contact principal qui passe d'une position de contact avec le premier contact principal fixe à une position de contact avec le deuxième contact principal fixe.
