Abstract

Un changeur de prises pour transformateurs électriques remplis d'huile, comprenant: un élément de guidage (2) pourvu d'une pluralité de contacts électriques (3) et un coulisseau (4) pouvant coulisser le long de l'élément de guidage (2) pour changer la connexion électrique entre deux ou plusieurs contacts électriques (3); des moyens de déplacement (5) du coulisseau (4) comprenant un groupe d'entraînement (6) comportant au moins une partie rotative (8) et définissant une pluralité de positions discrètes du chariot (4) par rapport à l'élément de guidage (2), chacun correspondant à une liaison électrique entre les différents contacts électriques (3). Les moyens de déplacement (5) comprenant: une bague-écrou (20) susceptible d'être mis en rotation par le groupe d'entraînement (6) et dont la surface latérale comporte deux ou plusieurs surfaces planes (21); un noyau (23) contre-déplacé avec la surface latérale de la bague-écrou (20), la partie (24) du noyau (23) face à la bague-écrou (20) ayant une surface plane (25) sensible à la être disposés un à un avec les surfaces planes (21) de la surface latérale de la bague-écrou (20) lorsque le coulisseau (4) et l'élément de guidage (2) sont placés en correspondance avec l'une des positions discrètes.A tap changer for oil-filled electrical transformers, comprising: a guide member (2) provided with a plurality of electrical contacts (3) and a slide (4) slidable along the guide member (2) ) to change the electrical connection between two or more electrical contacts (3); moving means (5) of the slide (4) comprising a drive unit (6) comprising at least one rotating part (8) and defining a plurality of discrete positions of the carriage (4) with respect to the guide element (2), each corresponding to an electrical connection between the various electrical contacts (3). The displacement means (5) comprising: a ring-nut (20) capable of being rotated by the drive unit (6) and the lateral surface of which comprises two or more flat surfaces (21); a core (23) counter-displaced with the lateral surface of the ring nut (20), the part (24) of the core (23) facing the ring nut (20) having a flat surface (25) sensitive to be arranged one by one with the flat surfaces (21) of the side surface of the nut ring (20) when the slider (4) and the guide member (2) are placed in correspondence with one of the discrete positions .
