Description
L'invention est relative à un dispositif de commande d'un disjoncteur électrique multipolaire à haute tension, ayant une pluralité de pôles séparés, disposés en ligne sur un châssis métallique avec un écartement prédéterminé, chaque pôle ayant une enceinte en forme de colonne, remplie d'un gaz à rigidité diélectrique élevée, notamment de l'hexaflorure de soufre, et renfermant un système de contacts séparables ayant un contact fixe et un contact mobile accouplé à une tige d'actionnement, et un dispositif d'extinction de l'arc, ledit dispositif de commande comportant :
- un mécanisme de commande, logé dans un coffret solidaire du châssis;
- un dispositif de transmission agencé à l'intérieur d'une poutre horizontale conformée en caisson creux, et comprenant un arbre intermédiaire rotatif s'étendant selon la direction longitudinale de la poutre pour transmettre l'énergie d'ouverture ou de fermeture du mécanisme aux tiges d'actionnement des pôles;
- une première manivelle de transmission logée à l'intérieur d'un carter individuel et étanche, prévu à la base de chaque pôle, dont l'enceinte communique avec le volume interne dudit carter;
- et une liaison mécanique pour relier cinématiquement la première manivelle à la tige d'actionnement du contact mobile correspondant.The invention relates to a device for controlling a high-voltage multipolar electrical circuit breaker, having a plurality of separate poles, arranged in line on a metal frame with a predetermined spacing, each pole having a column-shaped enclosure, filled a gas with high dielectric strength, in particular sulfur hexafloride, and containing a separable contact system having a fixed contact and a movable contact coupled to an actuating rod, and a device for extinguishing the arc , said control device comprising:
- a control mechanism, housed in a box secured to the chassis;
- A transmission device arranged inside a horizontal beam shaped as a hollow box, and comprising a rotary intermediate shaft extending in the longitudinal direction of the beam to transmit the opening or closing energy of the mechanism to pole actuation rods;

Un dispositif de commande comme du genre mentionné est décrit dans le document EP 94.858. L'arbre rotatif de transmission est subdivisé en plusieurs tronçons alignés s'étendant dans l'entraxe des pôles, en étant solidarisés au tronçon suivant par le moyeu de la manivelle dans lequel s'emboîtent les extrémités cannelées aboutées des tronçons successifs. Les trois enceintes des pôles communiquent entre elles par des éléments cylindriques intermédiaires de carter, autorisant une seule étanchéité dynamique. Un tel dispositif de commande convient parfaitement pour un disjoncteur ayant une tension d'utilisation spécifique, par exemple 72 kV. Pour réaliser une gamme de disjoncteurs couvrant une plage de tensions, il est par contre nécessaire de modifier la longueur des tronçons d'arbre et de carter, en fonction de l'écartement entre pôles imposé par la rigidité diélectrique du milieu environnant, ce qui pose des problèmes de standardisation et de stockage lors de la fabrication.A control device such as the one mentioned is described in document EP 94,858. The rotary drive shaft is subdivided into several aligned sections extending in the center distance of the poles, being secured to the next section by the hub of the crank in which fit the splined ends abutted successive sections. The three enclosures of the poles communicate with each other by intermediate cylindrical casing elements, allowing a single dynamic seal. Such a control device is perfectly suitable for a circuit breaker having a specific operating voltage, for example 72 kV. To produce a range of circuit breakers covering a range of voltages, it is however necessary to modify the length of the shaft and casing sections, as a function of the spacing between poles imposed by the dielectric strength of the surrounding medium, which poses standardization and storage problems during manufacturing.
L'objet de l'invention consiste à améliorer un dispositif de commande de disjoncteur à pôles séparés pour faciliter la modification de l'écartement des pôles en fonction de la tension d'utilisation.The object of the invention is to improve a circuit breaker control device with separate poles to facilitate the modification of the spacing of the poles as a function of the operating voltage.
Le dispositif de commande selon l'invention la première manivelle est portée par un demi-arbre rotatif traversant à étanchéité le carter selon la direction longitudinale de la poutre, et que le demi-arbre est accouplé à l'arbre intermédiaire par un système de transmission à bielle-manivelles.The control device according to the invention the first crank is carried by a rotary half-shaft sealingly passing through the casing in the longitudinal direction of the beam, and that the half-shaft is coupled to the intermediate shaft by a transmission system with crank rods.
Les demi-arbres de tous les pôles sont alignés selon une direction parallèle à l'arbre intermédiaire. Chaque carter comporte une plaque d'appui positionnée en un endroit prédéterminé de la poutre pour le montage du pôle correspondant, ou de sa colonne support.The half-shafts of all the poles are aligned in a direction parallel to the intermediate shaft. Each casing has a support plate positioned at a predetermined location on the beam for mounting the corresponding pole, or its support column.
Le système de transmission entre l'arbre intermédiaire et chaque demi-arbre comporte une deuxième manivelle portée par le demi-arbre à l'extérieur du carter, et reliée par une bielle de liaison à une troisième manivelle associée à l'arbre intermédiaire commun, le débattement dudit système s'effectuant au niveau de chaque carter dans un plan perpendiculaire à la direction longitudinale de la poutre.The transmission system between the intermediate shaft and each half-shaft comprises a second crank carried by the half-shaft outside the casing, and connected by a connecting rod to a third crank associated with the common intermediate shaft, the deflection of said system taking place at each casing in a plane perpendicular to the longitudinal direction of the beam.
L'arbre intermédiaire est monté à rotation dans trois paliers agencés dans des flasques solidaires des carters.The intermediate shaft is rotatably mounted in three bearings arranged in flanges integral with the casings.
L'écartement des pôles peut être facilement ajusté en fonction de la tension d'utilisation, par le positionnement de la zone de fixation du carter individuel de chaque pôle ou de sa colonne support sur la poutre horizontale. Toutes les pièces du dispositif de commande restent standard, à l'exception de l'arbre intermédiaire dont la longueur doit être adaptée à celle de la poutre.The pole spacing can be easily adjusted depending on the operating voltage, by positioning the attachment area of the individual casing of each pole or its support column on the horizontal beam. All parts of the control device remain standard, with the exception of the intermediate shaft, the length of which must be adapted to that of the beam.
Le caisson ouvert de la poutre est en liaison avec le milieu extérieur, et la communication interne des pôles s'opère au moyen d'un système de tuyauterie reliant les différents carters pour assurer une répartition uniforme de la pression de gaz isolant.The open box of the beam is in connection with the external environment, and the internal communication of the poles takes place by means of a piping system connecting the various casings to ensure a uniform distribution of the pressure of insulating gas.

Sur les figures, un disjoncteur 10 triphasé à haute tension comporte trois pôles 12, 14, 16 espacés, disposés en ligne sur un châssis 18 métallique, lequel est constitué par une poutre 20 horizontale creuse en forme de caisson, prenant appui sur un pied 22 central avec interposition du coffret 24 renfermant le mécanisme de commande 26. La base du pied 22 est scellée au sol 28 par des moyens de fixation 30 (fig.1 et 2).In the figures, a three-phase high-voltage circuit breaker 10 has three spaced-
Les pôles 12,14,16 sont portés par des colonnes supports 13, 15, 17 qui reposent directement sur la poutre 20. Chaque pôle comporte une enceinte étanche remplie de gaz isolant, notamment de l'hexaflorure de soufre. L'enceinte renferme un système de contacts séparables, et un dispositif de soufflage de l'arc, notamment à autoexpansion avec ou sans arc tournant, ou à autocompression par pistonnage. Le contact mobile du système de contacts est solidaire d'une tige d'actionnement 32 (fig. 3), laquelle est accouplée axialement au mécanisme 26 par une liaison mécanique 34 démontable, notamment du type à vis.The
La base de chaque colonne support 13, 15, 17 est fixée à étanchéité sur une plaque d'appui 36 d'un carter 38 fixe de logement d'une première manivelle 40 de transmission, sur laquelle est articulée la tige filetée 42 de la liaison mécanique 34. A l'intérieur de la poutre 20, les trois carters 38 identiques sont répartis à intervalles prédéterminés correspondant à l'écartement des pôles 12, 14, 16, et les trois manivelles 40 se débattent dans un plan perpendiculaire à la direction longitudinale de la poutre 20. Le volume interne de chaque carter 38 communique avec le pôle correspondant, et est rempli par du gaz SF6. A l'opposé de la plaque d'appui 36 de chaque carter 38, est agencé un tuyau 44 de répartition connecté à un réservoir 46 commun, lequel est relié à un manostat 48. Les volumes des trois pôles 12, 14, 16 communiquent entre eux par l'intermédiaire des trois tuyaux 44 et du réservoir 46 commun. Il en résulte une pression uniforme de SF6 dans les pôles. Toute baisse anormale de pression est signalée par le manostat 48.The base of each
Le mécanisme 26 est une commande mécanique du type décrit dans le brevet français No 1.586.097, et comporte un ressort de fermeture (non représenté) capable d'armer une paire de ressorts de déclenchement 50 au cours de la manoeuvre de fermeture des pôles 12, 14, 16. Le mécanisme 26 comporte des verrous d'accrochage en position d'ouverture et de fermeture permettant une commande d'enclenchement et de déclenchement, notamment à distance.The
Le mécanisme 26 peut également être, à commande hydraulique, pneumatique ou électrique.The
A l'intérieur du caisson de la poutre 20 se trouve également un dispositif de transmission 52 agencé entre le mécanisme de commande 26, et les trois tiges d'actionnement 32 des pôles 12, 14, 16. Le dispositif de transmission 52 comporte un arbre intermédiaire 54 portant dans la zone médiane une paire de manivelles de commande d'ouverture 56, et une paire de manivelles de commande de fermeture 58 actionnées respectivement par des bielles 60, 62 coopérant avec les ressorts de déclenchement 50 et d'enclenchement du mécanisme 26. L'arbre intermédaire 54 s'étend dans la direction longitudinale de la poutre 20, et est monté à rotation dans trois paliers 64 alignés, ménagés dans des flasques 66 fixés aux trois carters 38.Inside the box of the
La disposition symétrique des deux ressorts de déclenchement 50 permet de diminuer les contraintes mécaniques de l'arbre 54.The symmetrical arrangement of the two
La première manivelle 40 de transmission à l'intérieur de chaque carter 38 est portée par un demi-arbre 68 rotatif traversant le carter 38 avec interposition d'un joint 70 dynamique d'étanchéité tournante, du type décrit dans le brevet français No 2 267 498. A l'extérieur du carter 38, chaque demi-arbre 68 individuel porte une deuxième manivelle 72 de transmission reliée par une bielle 74 à une troisième manivelle 76 de transmission associée à l'arbre intermédiaire 54 commun. Les manivelles 72, 76 et la bielle 74 forment un système de transmission 71 individuel pour chaque pôle.The
Le fonctionnement de la commande des trois pôles 12, 14 16 ressort de la description précédente. Une commande d'ouverture ou de fermeture par le mécanisme 26 provoque la rotation de l'arbre intermédiaire 54 dans un sens ou dans l'autre, ce mouvement de rotation étant transmis aux tiges d'actionnement 32 individuelles des trois pôles 12, 14, 16, par l'intermédiaire de la troisième manivelle 76, la bielle de liaison 74, la deuxième manivelle 72, le demi-arbre 68, la première manivelle 40 et la tige filetée 42. Un tel agencement du dispositif de transmission 52 permet une adaptation aisée de l'écartement des pôles en fonction de la distance d'isolement dans l'air, qui dépend de la valeur de tension entre phase. Il suffit de modifier l'emplacement des plaques d'appui 36 des carters 38 sur la poutre 20, et d'adapter la longueur de l'arbre intermédiaire 54 à l'écartement longitudinal entre les pôles d'extrémités 12, 16. Toutes les pièces du dispositif de transmission 52 sont standard, indépendamment de la tension inter-phase, à l'exception de la poutre 20 et de l'arbre intermédiaire 54. Le caisson de la poutre 20 est ouvert, et communique avec le milieu extérieur. La communication gazeuse interne des pôles 12, 14, 16 s'opère pour les tuyaux 44 et le réservoir 46 de répartition de la pression interne de SF6, laquelle est contrôlée en permanence par le manostat 48.The operation of the control of the three
