L'invention concerne en particulier des appareils de ce type dans lesquels un des interrupteurs est un sectionneur de barre et l'autre des interrupteurs est un sectionneur de terre.In particular, the invention relates to apparatus of this type in which one of the switches is a bar switch and the other of the switches is an earthing switch.
Plus spécifiquement, l'invention se rapporte à ce type d'appareils de commutation dans lesquels chaque interrupteur, tel qu'un sectionneur comprend une paire de contacts constituée d'un contact fixe et d'un contact mobile en translation de sorte à se séparer mutuellement lors d'une commutation.More specifically, the invention relates to this type of switching apparatus in which each switch, such as a disconnector comprises a pair of contacts consisting of a fixed contact and a movable contact in translation so as to separate mutually when switching.
L'application principale est la moyenne ou haute tension électrique selon laquelle le sectionneur de barre et le sectionneur de terre sont disposés dans des enveloppes isolantes remplies chacune d'un gaz diélectrique sous atmosphère contrôlée, tel que du SF6.The main application is the medium or high electrical voltage in which the bar disconnector and the earthing switch are arranged in insulating envelopes each filled with a dielectric gas under a controlled atmosphere, such as SF6.
Habituellement, les manoeuvres mécaniques de ce type d'appareils sont indépendantes, assurées par deux commandes mécaniques distinctes et contrôlées par des dispositifs mécaniques ou électriques d'inter verrouillage.Usually, the mechanical maneuvers of this type of apparatus are independent, provided by two separate mechanical controls and controlled by mechanical or electrical interlocking devices.
Ces dispositifs d'interverrouillage, dont le but est d'assurer la sécurité des personnes et du matériel, ont pour fonction de permettre un maintien de la position du sectionneur de barre en position ouverte lorsque le sectionneur de terre est en position de fermeture, cette dernière ne devant pas avoir lieu en présence d'une tension électrique sur le circuit électrique principal.These interlocking devices, the purpose of which is to ensure the safety of persons and equipment, have the function of allowing the position of the bar switch to be kept in the open position when the earthing switch is in the closed position. last not to take place in the presence of an electrical voltage on the main electrical circuit.

Les structures des appareils de commutation divulgués dans les documents mentionnés ci-dessus présentent toutes l'inconvénient majeur d'avoir un encombrement important pour les deux fonctions sectionnement de terre et du sectionneur.The structures of the switching devices disclosed in the documents mentioned above all have the major disadvantage of having a large footprint for both earth breaking functions and the disconnector.
En outre, les structures des appareils divulgués ne sont pas optimales pour une utilisation en très haute tension car le capotage diélectrique des éléments de transmission (arbre, levier(s), biellette d'accouplement) est difficile à réaliser.In addition, the structures of the disclosed devices are not optimal for use in very high voltage because the dielectric cover of the transmission elements (shaft, lever (s), connecting rod) is difficult to achieve.
Enfin, le coût des appareils de commutation divulgués est important.Finally, the cost of disclosed switching devices is important.
L'encombrement, le coût et l'assemblage des appareils de commutation électrique comprenant deux interrupteurs, tels qu'ils sont actuellement proposés peuvent être encore améliorés.The size, cost and assembly of the electrical switching apparatus comprising two switches, as currently proposed, can be further improved.
Le but de l'invention est ainsi de proposer une amélioration des appareils de commutation dans ce sens.The object of the invention is thus to propose an improvement of the switching apparatus in this sense.
Pour ce faire, l'invention concerne un mécanisme de commande d'un appareil de commutation électrique comprenant deux interrupteurs, tels qu'un sectionneur de barre et un sectionneur de terre, dont chacun comprend une paire de contacts comprenant un contact fixe et un contact mobile en translation de sorte à se séparer mutuellement lors d'une commutation, dans lequel le mécanisme de commande comprend des moyens communs d'entraînement des contacts mobiles qui permettent l'ouverture d'un des interrupteurs tout en maintenant la fermeture de l'autre des interrupteurs et vice-versa, mécanisme dans lequel la forme géométrique, les dimensions ainsi que l'agencement des contacts mobiles et de leurs moyens d'entrainement permettent de croiser les courses de translation des contacts mobiles.To do this, the invention relates to a control mechanism of an electrical switching apparatus comprising two switches, such as a bar disconnector and an earthing switch, each of which comprises a pair of contacts comprising a fixed contact and a contact movable in translation so as to separate each other during a switch, wherein the control mechanism comprises common means for driving the movable contacts which allow the opening of one of the switches while now closing the other switches and vice versa, a mechanism in which the geometric shape, the dimensions and the arrangement of the movable contacts and their drive means allow to cross the translation travel of the movable contacts.
Par « croiser les courses de translation », il faut comprendre ici et dans le cadre de l'invention que, vu selon une direction correspondant à celle de l'axe de rotation, les contacts mobiles ont des courses de translation qui s'imbriquent ou, autrement dit, se chevauchent.By "crossing the translation races", it should be understood here and in the context of the invention that, seen in a direction corresponding to that of the axis of rotation, the movable contacts have translational strokes which interlock or in other words, overlap.
Ainsi, grâce à l'imbrication des courses de translation des contacts mobiles il est possible de réduire les distances allant de l'amenée du courant, jusqu'aux contacts fixes de chacun des deux interrupteurs, tels que le sectionneur de barre ou le sectionneur de terre. L'encombrement d'un appareil de commutation électrique dans le plan de translation des deux interrupteurs selon l'invention, est donc réduit par rapport aux appareils selon l'art antérieur.Thus, thanks to the interlocking of the translation races of the movable contacts it is possible to reduce the distances going from the supply of the current, to the fixed contacts of each of the two switches, such as the bar disconnector or the disconnector. Earth. The size of an electrical switching device in the plane of translation of the two switches according to the invention is reduced compared to the apparatus according to the prior art.
En outre, en réduisant l'encombrement, on réduit le coût d'un tel appareil. En effet, les dimensions de la cuve métallique dans laquelle est logé un appareil de commutation selon l'invention sont réduites, ce qui réduit en conséquence ses coûts matière, de transport...In addition, by reducing the size, it reduces the cost of such a device. Indeed, the dimensions of the metal vessel in which is housed a switching device according to the invention are reduced, which consequently reduces its material costs, transport ...
Selon un mode de réalisation avantageux de l'invention,
- les moyens d'entraînement communs comprennent :
- ■ un axe de rotation,
- ■ une pièce solidaire de l'axe de rotation et comprenant deux leviers distincts avec l'un ayant la forme d'un étrier,
- ■ le mécanisme comprend deux paires de leviers articulés entre eux, l'un des leviers de chaque paire étant l'un des leviers distincts de la pièce solidaire de l'axe de rotation, et l'autre des leviers de chaque paire étant articulé à l'un des contacts mobiles ; les dimensions des leviers ainsi que leur agencement et celui de l'axe de rotation étant tels que l'étrier entoure le contact mobile auquel il est relié sur au moins une partie de sa course de translation.
- common training means include:

Selon ce mode de réalisation et une variante de réalisation préférée,
- le contact mobile, tel que le contact mobile du sectionneur de barre, relié au levier en étrier a une forme de tube creux,
- l'autre des leviers articulé au tube creux et au levier en étrier a une forme allongée, l'articulation du levier allongé au tube creux étant agencé à l'intérieur du tube creux à une hauteur suffisante pour permettre à une partie de la longueur du levier allongé d'y être logée sur la course de translation du tube creux.
- the movable contact, such as the movable contact of the bar switch, connected to the stirrup lever has a hollow tube shape,
- the other of the levers hinged to the hollow tube and the stirrup lever has an elongated shape, the articulation of the elongated lever to the hollow tube being arranged inside the hollow tube at a height sufficient to allow a part of the length of the elongated lever to be housed therein on the travel path of the hollow tube.
Selon une variante avantageuse, le tube creux présente une fente réalisée sur une partie de sa hauteur depuis son extrémité opposée à celle en regard du contact fixe associé, cette fente étant agencée pour permettre au levier allongé de s'y insérer lors de la translation du tube creux et d'augmenter sa course de translation de sa position d'ouverture à sa position de fermeture.According to an advantageous variant, the hollow tube has a slot made over part of its height from its opposite end to that facing the associated fixed contact, this slot being arranged to allow the elongate lever to be inserted during the translation of the hollow tube and increase its stroke of translation of its open position to its closed position.

Selon une variante préférée :
- l'autre des leviers de la pièce solidaire de l'axe de rotation a une forme droite ;
- le contact mobile, tel que le contact mobile du sectionneur de terre, relié au levier de forme droite a une forme de tige pleine.
- the other levers of the integral part of the axis of rotation has a straight form;
- the movable contact, such as the movable contact of the earthing switch, connected to the straight form lever has a solid rod shape.
Ainsi, en superposant en quelque sorte un tube creux avec une tige pleine de dimensions réduites on réduit l'encombrement de l'appareil selon l'axe de rotation par rapport à un appareil à deux contacts mobiles sous la forme de tube creux.Thus, by somehow superimposing a hollow tube with a solid rod of reduced dimensions reduces the size of the device along the axis of rotation relative to a device with two movable contacts in the form of hollow tube.
Selon cette dernière variante préférée, le levier articulé entre le levier droit solidaire de l'axe de rotation et la tige pleine a une forme incurvée permettant de réduire les efforts radiaux sur la tige à proximité de sa position de fermeture.According to this last preferred variant, the lever articulated between the right lever secured to the axis of rotation and the solid rod has a curved shape to reduce the radial forces on the rod near its closed position.
Selon cette variante préférée, la tige pleine présente une fente réalisée sur une partie de sa hauteur depuis son extrémité opposée à celle en regard du contact fixe associé, cette fente étant agencée pour permettre au levier incurvé de s'y insérer lors de la translation de la tige et, d'augmenter à la fois sa course de translation de sa position d'ouverture à sa position de fermeture et la course de translation du tube creux.According to this preferred variant, the solid rod has a slot made over part of its height from its opposite end to that opposite the associated fixed contact, this slot being arranged to allow the curved lever to be inserted during the translation of the rod and to increase both its translational stroke from its open position to its closed position and the translational travel of the hollow tube.

- one of the movable contacts, such as the movable contact of the bar disconnector, has a hollow tube shape,
- the other movable contact, such as the movable contact of the earthing switch, has a solid rod shape,
- the common drive means comprise an axis of rotation,
- the mechanism comprises two drive assemblies for each transforming the rotational movement of the axis to the translational movement to one of the movable contacts, each of the assemblies comprising a driving part integral with the axis of rotation, the two driving assemblies being arranged in parallel with each other so that when the solid rod and the movable hollow tube are in an intermediate position between their closed and open position, they are immediately adjacent to each other. the other at a distance e sufficient to allow their translation without friction between them.
En laissant une distance suffisante entre les deux ensembles d'entrainement uniquement pour permettre la translation de la tige pleine et du tube creux sans friction entre eux, on conserve un encombrement réduit dans le plan orthogonal aux interrupteurs et selon l'axe de rotation.By leaving a sufficient distance between the two drive assemblies only to allow the translation of the solid rod and the hollow tube without friction between them, one retains a reduced space in the plane orthogonal to the switches and along the axis of rotation.
Selon une variante, au moins un des deux ensembles d'entraînement est constitué d'une paire de leviers dont celui d'entraînement solidaire de l'axe de rotation et l'autre articulé à l'un des contacts mobiles et au levier d'entraînement.According to one variant, at least one of the two drive assemblies consists of a pair of levers, one of which is integral with the axis of rotation and the other articulated with one of the movable contacts and with the lever of training.
Selon une autre variante, un des deux ensembles d'entraînement, tels que celui du contact mobile de sectionneur de barre, est constitué d'une came à disque solidaire de l'axe de rotation et d'une paire de leviers, un des leviers comprenant une extrémité est fixée à un point d'articulation fixe et l'autre est articulée à l'autre des leviers lui-même articulé à l'un des contacts mobiles, le levier à un point d'articulation fixe comprenant un ergot agencé entre ses deux extrémités et logé dans une rainure pratiquée dans la came en formant un suiveur, mécanisme dans lequel la forme géométrique, la longueur et l'agencement de la paire de leviers, et le profil de la rainure de came permette d'avoir un rapport d'entraînement supplémentaire entre la came à disque et le contact mobile associé. Par l'expression « rapport d'entraînement supplémentaire entre la(es) came(s) à disque et chaque contact mobile associé », il faut comprendre ici et dans le cadre de l'invention un rapport d'entrainement supplémentaire à un entrainement selon lequel le contact mobile est directement articulé à une rainure de came à disque, comme par exemple montré dans le document
L'invention concerne également un appareil de commutation électrique comprenant une enveloppe dans laquelle sont logés au moins partiellement les contacts mobiles de deux interrupteurs, tels qu'un sectionneur de barre et un sectionneur de terre et un mécanisme de commande décrit précédemment.The invention also relates to an electrical switching apparatus comprising a casing in which are housed at least partially the movable contacts of two switches, such as a bar switch and an earthing switch and a control mechanism described above.
Cet appareil peut comprendre un tube de guidage pour guider un des contacts mobiles sur une partie de sa course de translation.This apparatus may comprise a guide tube for guiding one of the movable contacts on a part of its translation travel.
Le contact mobile guidé par le tube de guidage est avantageusement la tige de mise à la terre.The movable contact guided by the guide tube is advantageously the grounding rod.
L'invention concerne enfin un poste de moyenne et haute tension sous cuve métallique, comportant, au moins pour une phase, un appareil de commutation électrique mentionné ci-dessus.Finally, the invention relates to a medium and high voltage sub-tank, comprising, at least for one phase, an electrical switching apparatus mentioned above.
De préférence, un poste de moyenne et haute tension sous cuve métallique selon l'invention a, pour chaque phase, l'enveloppe de l'appareil de commutation électrique décrit ci-dessus qui est logée dans une cuve métallique donnée.Preferably, a medium and high voltage sub-tank according to the invention has, for each phase, the envelope of the electrical switching apparatus described above which is housed in a given metal tank.
Le poste selon l'invention peut ainsi avoir les trois cuves métalliques reliées entre elles par un système de tringlerie déplacé en translation par un actionneur et adapté pour mettre en rotation simultanément les mécanismes de commande des appareils.The station according to the invention can thus have the three metal tanks interconnected by a linkage system moved in translation by an actuator and adapted to simultaneously rotate the control mechanisms of the apparatus.
