Title
(EN) FOUR-WAY AUTOMATIC TRANSFER SWITCH
(FR) COMMUTATEUR DE TRANSFERT AUTOMATIQUE À QUATRE VOIES
Abstract
(EN)
A system includes a first group of cassettes, each cassette including a first stationary bar, a first plurality of fixed contact members, and a first plurality of movable contact members, each of which is electrically coupled and rotatably connected to the first stationary bar and configured to contact one of the first plurality of fixed contact members. The system includes a second group of cassettes each including a second stationary bar, a second plurality of fixed contact members, and a second plurality of movable contact members, each of which is electrically coupled and rotatably connected to the second stationary bar and configured to contact one of the second plurality of fixed contact members. The system includes at least one operating mechanism to control opening and closing of the movable contact members. The first stationary bar is coupled to the second stationary bar.

L'invention concerne un système comprenant un premier groupe de cassettes, chaque cassette comprenant une première barre fixe, une première pluralité d'éléments de contact fixes, et une première pluralité d'éléments de contact mobiles, chacun d'eux étant couplé électriquement et relié rotatif à la première barre fixe et configuré pour venir en contact avec l'un de la première pluralité d'éléments de contact fixes. Le système comprend un second groupe de cassettes comprenant chacune une seconde barre fixe, une seconde pluralité d'éléments de contact fixes, et une seconde pluralité d'éléments de contact mobiles, chacun d'eux étant couplé électriquement et relié rotatif à la seconde barre fixe et configuré pour venir en contact avec l'un de la seconde pluralité d'éléments de contact fixes. Le système comprend au moins un mécanisme d'actionnement pour commander l'ouverture et la fermeture des éléments de contact mobiles. La première barre fixe est couplée à la seconde barre fixe.
