Abstract

La présente invention concerne un changeur de prise pourvu d'un présélecteur, servant à réaliser une commutation sans interruption entre les différentes prises d'enroulement d'un transformateur à prises. L'idée inventive générale réside dans le fait d'utiliser, au lieu des lamelles individuelles articulées au moyen de ressorts séparés, deux tôles de contact agencées de manière sensiblement parallèle l'une à l'autre, qui sont guidées parallèlement au moyen de tôles en étrier et peuvent être comprimées au moyen de ressorts à branches, de sorte que des contacts de présélection adjacents fixes d'une phase peuvent être logés entre les faces des tôles de contact se trouvant en regard.
