Description

La présente invention se rapporte à un sélecteur de prises en charge pour transformateur à échelons. Dans ce type d'appareil, les différentes prises constituant les contacts fixes sont reliés électriquement aux sorties des échelons du transformateur. Ces différentes prises sont disposées, à distance diélectrique suffisante l'une de l'autre, sur la paroi interne d'un cylindre isolant, faisant office de récipient d'huile, à l'intérieur duquel se déplacent des contacts mobiles. Selon la tension d'échellon, correspond une distance diélectrique entre contacts fixes voisins. En conséquence, pour un type d'appareil, le nombre de contacts fixes disposés sur le cylindre isolant est proportionnel au diamètre de ce cylindre. Dans ces appareils, l'augmentation de nombre de contacts fixes conduit nécessairement à l'accroissement du diamètre du tube isolant. Généralement, ces variations de diamètre entraînent des modifications importantes des éléments constitutifs de l'appareil et augmentent le nombre de pièces différentes à maintenir en magasin.The present invention relates to a tap selector for stepped transformers. In this type of device, the different sockets constituting the fixed contacts are electrically connected to the outputs of the steps of the transformer. These different sockets are arranged, at a sufficient dielectric distance from each other, on the internal wall of an insulating cylinder, acting as an oil container, inside of which move movable contacts. Depending on the step voltage, there is a dielectric distance between neighboring fixed contacts. Consequently, for a type of device, the number of fixed contacts arranged on the insulating cylinder is proportional to the diameter of this cylinder. In these devices, the increase in the number of fixed contacts necessarily leads to an increase in the diameter of the insulating tube. Generally, these variations in diameter cause significant modifications to the components of the device and increase the number of different parts to be kept in store.

Le but de la présente invention est d'utiliser un nombre maximum d'éléments identiques pour couvrir différentes classes d'appareil et ainsi réduire les frais de fabrication et de gestion des stocks. Ce but est atteint en modifiant judicieusement la géométrie d'un nombre restreint d'éléments.The object of the present invention is to use a maximum number of identical elements to cover different classes of device and thus reduce manufacturing costs and inventory management. This goal is achieved by judiciously modifying the geometry of a limited number of elements.

L'invention consiste essentiellement à utiliser, au niveau du sélecteur, d'une part un arbre coudé permettant de conserver les mêmes modules de commutation d'autre part des couronnes d'adaptation pour raccorder la cuvette et le carter du mécanisme de commande à un cylindre isolant de plus grand diamètre.The invention essentially consists in using, at the level of the selector, on the one hand a bent shaft making it possible to keep the same switching modules on the other hand adaptation rings for connecting the bowl and the housing of the control mechanism to a larger diameter insulating cylinder.

L'invention est exposée, ci-après, plus en détail à l'aide d'un dessin représentant seulement un mode d'exécution.The invention is set out below in more detail with the aid of a drawing representing only one embodiment.

La figure 1 est une vue en coupe de l'ensemble d'un sélecteur de charge.Figure 1 is a sectional view of the assembly of a charge selector.

Dans cette figure, le sélecteur de charge comprend un cylindre isolant 1 portant à la périphérie de la paroi intérieure des contacts fixes de sélecteur 2 et des couronnes de point commun 3 qui se raccordent aux échelons des trois phases du transformateur. Des 12.30/1923 contacts fixes d'inverseur 4 sont montés dans la partie supérieure du cylindre isolant 1.In this figure, the load selector comprises an insulating cylinder 1 carrying, at the periphery of the inner wall, fixed selector contacts 2 and common point rings 3 which are connected to the steps of the three phases of the transformer. From 12.30 / 1923 fixed changeover contacts 4 are mounted in the upper part of the insulating cylinder 1.

Les contacts fixes de sélecteur 2 et les couronnes de point commun 3 collaborent pour chaque phase avec un module de commutation de sélecteur 5.The fixed selector 2 contacts and the common point crowns 3 collaborate for each phase with a selector switching module 5.

Les modules de commutation de sélecteur 5 sont addosés à un tube isolant 6 constituant la partie décentrée d'un arbre de commande coudé 7.The selector switching modules 5 are added to an insulating tube 6 constituting the off-center part of a bent control shaft 7.

Cet arbre de commande coudé 7 se compose d'un élément d'accouplement mâle 8, d'un élément d'accouplement femelle 9 associé à un coude supérieur 10, du tube isolant 6, appelé par la suite tube isolant décentré 6, d'un coude inférieur 11 réuni à une extrémité conique 12 par l'intermédiaire d'un roulement 13 appelé palier inférieur 13.This bent control shaft 7 consists of a male coupling element 8, a female coupling element 9 associated with an upper elbow 10, of the insulating tube 6, hereinafter called off-center insulating tube 6, a lower bend 11 joined at a conical end 12 by means of a bearing 13 called the lower bearing 13.

L'arbre de commande 7 est centré et entraîné à sa partie supérieure par l'élément d'accouplement mâle 8 tournant dans un roulement 14, appelé palier supérieur 14, et supporté par un flasque 15 d'un carter 16 renfermant un mécanisme de commande 17 qui actionne l'élément d'accouplement mâle 8. La section transversale de l'élément d'accouplement mâle 8 est de forme non circulaire et s'engage dans une empreinte de même configuration de d'élément d'accouplement femelle 9. L'extrémité conique 12 est centrée par l'interposition d'une douille 18 sur un support de palier 19 solidaire d'une cuvette 20 servant de fond au récipient d'huile. Cette'cuvette 20, conçue pour un tube isolant de plus petit diamètre, est raccordée au cylindre isolant 1 par une couronne inférieure de raccordement 21.The control shaft 7 is centered and driven at its upper part by the male coupling element 8 rotating in a bearing 14, called the upper bearing 14, and supported by a flange 15 of a casing 16 containing a control mechanism 17 which actuates the male coupling element 8. The cross section of the male coupling element 8 is of non-circular shape and engages in an imprint of the same configuration of the female coupling element 9. L 'conical end 12 is centered by the interposition of a socket 18 on a bearing support 19 secured to a bowl 20 serving as the bottom of the oil container. Ce'uvuv 20, designed for an insulating tube of smaller diameter, is connected to the insulating cylinder 1 by a lower connection ring 21.

Un conduit de siphonage peut être prévu traversant l'arbre de commande coudé 7 et permettant d'aspirer l'huile du récipient. Ce conduit est accessible de l'extérieur par un tube de raccordement 22 qui se prolonge à travers le mécanisme de commande 17 pour se terminer par un tube de vidange 23 disposé verticalement dans un alésage axial, de plus grand diamètre, de l'élément d'accouplement même 8 et maintenu centré par un joint d'étanchéité 24 placé dans l'élément d'accouplement femelle 9. A l'exception du frottement exercé par le joint d'étanchéité 24, le tube de vidange 23 ne supporte aucun effort mécanique. Le tube de vidange 23 aboutit à un conduit coudé 25, interne à l'élément d'accouplement femelle 9 et au coude supérieur 10. Le conduit coudé 25 peut ensuite être relié à un tube de siphonage 26 maintenu dans l'axe, repéré 27, du tube isolant décentré 6 par le coude supérieure 10 et le coude inférieur 11. L'extrémité inférieure du tube de siphonage 26 débouche dans un trou 28 fait dans le coude inférieur 11 suivant l'axe 27 pour servir d'ajutage 28.A siphoning pipe can be provided passing through the bent control shaft 7 and making it possible to draw the oil from the container. This duct is accessible from the outside by a connection tube 22 which extends through the control mechanism 17 to end in a drain tube 23 arranged vertically in an axial bore, of larger diameter, of the element d coupling 8 and kept centered by a seal 24 placed in the female coupling element 9. With the exception of the friction exerted by the seal 24, the drain tube 23 does not support any mechanical force . The tube drain 23 leads to a bent pipe 25, internal to the female coupling element 9 and to the upper elbow 10. The bent pipe 25 can then be connected to a siphoning tube 26 held in the axis, marked 27, of the insulating tube off-center 6 by the upper elbow 10 and the lower elbow 11. The lower end of the siphoning tube 26 opens into a hole 28 made in the lower elbow 11 along the axis 27 to serve as a nozzle 28.

Des joints d'étanchéité 29 sont prévus aux deux extrémités de tube de siphonage 26.Seals 29 are provided at the two ends of the siphoning tube 26.

Ce carter 16, conçu pour un tube isolant de plus petit diamètre est raccordé au cylindre isolant 1 par une couronne spérieure de raccordement 30. Le carter 16 porte sur toute sa périphérie un épaulement 31 qui se raccorde à la cuve du transformateur.This casing 16, designed for an insulating tube of smaller diameter is connected to the insulating cylinder 1 by a spherical connection ring 30. The casing 16 carries over its entire periphery a shoulder 31 which is connected to the transformer tank.

L'accouplement femelle 9 soutient à sa base un roulement 32 qui équipe un plateau 33 solidarisé à un tube isolant d'inverseur 34 sur lequel sont montés des contacts mobiles d'inverseur 35. Le plateau 33 porte une boutonnière 36 dans laquelle s'engage un ergot d'entraînement 37 actionné par le mécanisme de commande 17. Ce mécanisme de commande 17 actionne, de manière indépendante, l'inverseur par l'intermédiaire de l'ergot d'entraînement 37 et le sélecteur par l'intermédiaire de l'accouplement mâle 8.The female coupling 9 supports at its base a bearing 32 which equips a plate 33 secured to an inverter insulating tube 34 on which are movable inverter contacts 35. The plate 33 carries a buttonhole 36 in which engages a drive lug 37 actuated by the control mechanism 17. This control mechanism 17 independently actuates the reverser via the drive lug 37 and the selector via the male coupling 8.

Le cylindre isolant 1 en collaboration avec la cuvette 20, la couronne inférieure de raccordement 21, le carter 16 muni d'un couvercle 38 et la couronne supérieure de raccordement 30 fait office de récipient d'huile pour l'ensemble de l'appareil.The insulating cylinder 1 in collaboration with the bowl 20, the lower connection ring 21, the casing 16 provided with a cover 38 and the upper connection ring 30 acts as an oil container for the entire appliance.

L'étanchéité de ce récipient d'huile est assurée par des joints 39, 40, 41, 42, 43 disposés dans des rainures faites respectivement dans la couronne inférieure de raccordement 21, dans la couronne supérieure de raccordement 30 et dans le couvercle 38.This oil container is sealed by seals 39, 40, 41, 42, 43 arranged in grooves made respectively in the lower connection ring 21, in the upper connection ring 30 and in the cover 38.

Le tube isolant 1, portant les contacts fixes de l'inverseur 4, les contacts fixes du sélecteur 2 et les couronnes de point commun 3, sont concentriques autour d'un même axe 44 appelé axe de l'appareil 44.The insulating tube 1, carrying the fixed contacts of the reverser 4, the fixed contacts of the selector 2 and the crowns of common point 3, are concentric around a same axis 44 called the axis of the device 44.

Le tube isolant décentré 6, portant les modules de commutation de sélecteur 5 a un axe de symétrie de révolution appelé axe de la partie coudée 27. Ce tube isolant décentré 6 constitue la partie coudée de l'arbre de commande 7 qui prend appui sur le palier inférieur 13 et sur le palier supérieur tous deux concentriques à l'axe de l'appareil 44.The off-center insulating tube 6, carrying the selector switching modules 5 has an axis of symmetry of revolution called the axis of the bent part 27. This off-center insulating tube 6 constitutes the bent part of the control shaft 7 which bears on the lower bearing 13 and on the upper bearing, both concentric with the axis of the apparatus 44.

La partie supérieure du tube isolant décentré 6 se déplace à l'intérieur du tube isolant d'inverseur 34. Selon la classe de l'appareil, la partie de recouvrement du tube isolant décentré 6 et du tube isolant de l'inverseur 34 est plus ou moins importante selon la distance à ménager entre les contacts fixes de l'inverseur 4 et le plateau 33.The upper part of the off-center insulating tube 6 moves inside the inverter insulating tube 34. Depending on the class of the device, the covering part of the off-center insulating tube 6 and the insulating tube of the inverter 34 is more or less depending on the distance to be left between the fixed contacts of the reverser 4 and the plate 33.

Les modules de commutation de sélecteur 5 sont normalement montés sur le tube isolant décentré 6 selon la génératrice contenue dans le plan formé par l'axe de l'appareil 44 et l'axe de la partie coudée 27 au droit des contacts fixes de sélecteur 2. Toutefois, pour adapter les mêmes modules de commutation de sélecteur 5 à une plus large gamme de diamètres du tube isolant 1, ces modules peuvent être montés dans une position s'écartant plus ou moins fortement de la position normale précédemment définie. Un même résultat pourrait d'ailleurs être obtenu par la forme circulaire de la section de ce cylindre isolant décentré 6 par une forme elliptique et en disposant des semelles ajustables en rotation sur le coude inférieur 11 et le coude supérieur 10. La couronne inférieure de raccordement 21 et la couronne supérieure de raccordement 30 sont de préférence identiques entre elles et d'une forme appropriée pour être facilement mise au diamètre extérieur désiré.The selector switching modules 5 are normally mounted on the off-center insulating tube 6 according to the generator contained in the plane formed by the axis of the device 44 and the axis of the bent part 27 in line with the fixed selector 2 contacts However, to adapt the same selector switching modules 5 to a wider range of diameters of the insulating tube 1, these modules can be mounted in a position deviating more or less strongly from the normal position previously defined. The same result could also be obtained by the circular shape of the section of this off-center insulating cylinder 6 by an elliptical shape and by having soles adjustable in rotation on the lower elbow 11 and the upper elbow 10. The lower connection crown 21 and the upper connection ring 30 are preferably identical to each other and of a suitable shape so as to be easily set to the desired external diameter.

Dans cet exemple de réalisation, les résistances de passage, non représentées, sont disposées'autour du tube isolant décentré 6 dans une gaine moulée, se prolongeant dans l'espace libre situé à la partie inférieure de chaque module de commutation de sélecteur 5, et conformée pour soutenir le contact mobile se déplaçant en face de chaque couronne de point commun 3.In this exemplary embodiment, the passage resistors, not shown, are arranged around the off-center insulating tube 6 in a molded sheath, extending into the free space located at the bottom of each selector switching module 5, and shaped to support the moving contact moving in front of each common point crown 3.

Lorsque les modules de commutation de sélecteur 5 sont au potentiel du point neutre, le tube isolant décentré 6 peut être remplacé sur une partie de sa longueur par un tube métallique.When the selector switch modules 5 are at the neutral point potential, the off-center insulating tube 6 can be replaced over a part of its length by a metal tube.
