Abstract

L'invention concerne un commutateur à gradins pour la commutation sans interruption entre deux points de raccordement du bobinage d'un transformateur à gradins. Ledit commutateur comporte deux branches de charge, la première branche étant reliée au premier point de raccordement du bobinage, et la deuxième branche, au deuxième point de raccordement du bobinage. Chacune des branches de charge comprend au moins un élément de commutation jouant le rôle de contact principal et est reliée à une ligne de charge commune. Selon l'invention, il est disposé, sur la première branche de charge un premier contact mécanique de commutation grâce auquel le côté du premier élément de commutation jouant le rôle de contact principal qui est à l'opposé de la ligne de charge peut être relié au choix au premier point de raccordement ou au deuxième point de raccordement du bobinage, et il est disposé, sur la deuxième branche de charge, un deuxième contact mécanique de commutation grâce auquel le côté du deuxième élément de commutation jouant le rôle de contact principal qui est à l'opposé de la ligne de charge peut également être relié au choix au premier point de raccordement ou au deuxième point de raccordement du bobinage. De cette manière, le courant permanent qui s'écoule en régime permanent est avantageusement partagé entre les éléments de commutation des deux branches de charge.
