Abstract

L'invention concerne un changeur de prise du type sélecteur de charge pour la commutation sans interruption entre des prises d'enroulements d'un transformateur à prises. Des contacts à prises (8) fixes, respectivement dans un plan séparé, sont disposés dans la paroi d'un cylindre en matériau isolant (7) pour chaque phase à commuter, lesdits contacts fixes pouvant être connectés par l'intermédiaire de contacts mobiles (3, 4, 5) agencés sur un porte-contact (2) et faisant office de contact de résistance (3, 4) ou de contact de commutation (5). Les contacts de résistance (3, 4) comme le contact de commutation (5) se présentent sous la forme de galets de contact de résistance (3, 4) et sous la forme d'un galet de contact de commutation (5), les galets de contact de résistance (3, 4) étant placés dans un premier plan horizontal et le galet de contact de commutation (5) étant placé dans un autre plan horizontal sur le porte-contact. Les contacts à prises (8) présentent une forme allongée verticalement de façon à pouvoir être connectés respectivement au moyen des galets de contact (3, 4, 5) dans les deux plans.
