Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un appareil électrique interrupteur triphasé présentant une architecture modulaire, en particulier un appareil interrupteur opérant sous moyenne ou haute tension, c'est-à-dire opérant à une tension supérieure à 1000V. L'invention concerne également un module central d'un tel appareil interrupteur.The present invention relates to a three-phase electrical switch device having a modular architecture, in particular a switch device operating at medium or high voltage, that is to say operating at a voltage greater than 1000V. The invention also relates to a central module of such a switch device.

Dans le présent document, le terme «appareil interrupteur» regroupe indifféremment plusieurs types d'appareils électriques comme un interrupteur, un disjoncteur, un contacteur, un interrupteur fusible, un recloser, un sectionneur, etc.In this document, the term "switch device" interchangeably includes several types of electrical devices such as a switch, a circuit breaker, a contactor, a fuse switch, a recloser, a disconnector, etc.

Etat de la techniqueState of the art

Les appareils interrupteurs triphasés existent généralement soit avec une architecture dite frontale dans laquelle les trois pôles de l'appareil sont placés les uns à côté des autres selon une direction sensiblement parallèle à la face avant de l'appareil interrupteur, soit avec une architecture dite longitudinale dans laquelle les trois pôles de l'appareil sont placés les uns derrière les autres dans une direction sensiblement perpendiculaire à la face avant de l'appareil interrupteur.Three-phase switching devices generally exist either with a so-called frontal architecture in which the three poles of the device are placed next to each other in a direction substantially parallel to the front face of the switching device, or with a so-called longitudinal architecture. in which the three poles of the device are placed one behind the other in a direction substantially perpendicular to the front face of the switching device.

Une architecture frontale est par exemple bien adaptée aux contraintes des appareils destinés à être placés dans des cellules haute tension dites primaires, alors qu'une architecture longitudinale est par exemple bien adaptée aux contraintes des appareils placés dans des cellules haute tension dites secondaires dont les dimensions sont souvent plus réduites.A front-end architecture is for example well suited to the constraints of devices intended to be placed in so-called primary high-voltage cells, while a longitudinal architecture is for example well-suited to the constraints of devices placed in so-called secondary high-voltage cells whose dimensions are often smaller.

D'autre part, il est connu que les distances à respecter entre chaque phase d'un appareil interrupteur peuvent être différentes en fonction de la tension nominale et du courant nominal d'utilisation de l'appareil, pour des raisons évidentes de contraintes diélectriques liées à la tension et des contraintes d'échauffement dues au courant.On the other hand, it is known that the distances to be observed between each phase of a switching device may be different depending on the nominal voltage and the nominal operating current of the device, for obvious reasons of dielectric constraints associated with voltage and heating constraints due to current.

Le document EP2437277 décrit un agencement pour un disjoncteur haute tension multiphases en architecture frontale et dont les pôles sont montés de telle sorte que la distance entre pôles peut être facilement réglée, par exemple grâce à différents types d'organes de raccordement intermédiaires entre les pôles. Ce document décrit également un module central selon le préambule de la revendication 1.The document EP2437277 describes an arrangement for a multi-phase high voltage circuit breaker in frontal architecture and whose poles are mounted such that the distance between poles can be easily adjusted, for example by means of different types of intermediate connecting members between the poles. This document also describes a central module according to the preamble of claim 1.

Un des buts de l'invention est de pouvoir rationaliser la fabrication et la gestion industrielle des appareils interrupteurs, c'est-à-dire d'être capable de fabriquer très facilement des appareils selon l'une ou l'autre des architectures et selon différents calibres et tensions en utilisant le minimum de pièces différentes, de façon à diminuer les coûts et à simplifier le processus de fabrication.One of the aims of the invention is to be able to rationalize the manufacture and industrial management of switch devices, that is to say to be able to very easily manufacture devices according to one or the other of the architectures and according to different gauges and voltages using the minimum number of different parts, in order to reduce costs and simplify the manufacturing process.

Pour cela, l'appareil interrupteur selon l'invention est conçu selon une structure modulaire en utilisant au maximum des modules standardisés en fonction de l'utilisation prévue par les clients, ce qui permet donc de réaliser, le plus tard possible dans la chaîne de fabrication et de montage de l'appareil, une personnalisation de l'architecture et le choix du courant et de la tension de l'appareil interrupteur.For this, the switch device according to the invention is designed according to a modular structure by using standardized modules as much as possible according to the use foreseen by the customers, which therefore makes it possible to carry out, as late as possible in the chain of manufacture and assembly of the device, customization of the architecture and the choice of current and voltage of the switch device.

Un appareil interrupteur électrique de construction modulaire dispose d'un module interrupteur pour chaque phase d'un réseau d'alimentation électrique. Dans le cas d'un appareil triphasé, il y a donc trois modules interrupteurs. De façon classique, chaque module interrupteur est capable de couper une phase du réseau d'alimentation électrique grâce à un (ou éventuellement plusieurs) contact mobile qui coopère avec un (ou plusieurs) contact fixe. En position dite ouverte le contact mobile est séparé du contact fixe, et en position dite fermée le contact mobile est connecté au contact fixe. L'actionnement des contacts mobiles des différents modules interrupteurs d'un appareil interrupteur doit être effectué de façon mécaniquement synchronisée pour assurer par exemple la commutation simultanée de toutes les phases du réseau d'alimentation électrique, à l'ouverture comme à la fermeture.An electrical switch device of modular construction has a switch module for each phase of an electrical supply network. In the case of a three-phase device, there are therefore three switch modules. Conventionally, each switch module is capable of cutting a phase of the electrical supply network by virtue of one (or possibly more) mobile contact which cooperates with one (or more) fixed contact. In the so-called open position the movable contact is separated from the fixed contact, and in the so-called closed position the movable contact is connected to the fixed contact. The actuation of the movable contacts of the various switch modules of a switch device must be carried out in a mechanically synchronized manner to ensure, for example, the simultaneous switching of all the phases of the electrical supply network, both on opening and on closing.

La figure 1 montre un module central 10 qui est destiné à un appareil interrupteur de conception modulaire. Ce module central 10 comporte un socle central 11 de base qui est surmonté par une face avant 18. La face avant 18 comprend notamment divers organes de contrôle/commande 19 qui permettent par exemple à un opérateur de piloter et surveiller l'appareil interrupteur. Le socle central 11 est destiné à porter un premier module interrupteur, appelé module interrupteur central 15 (voir figures 2 et 3).The figure 1 shows a central module 10 which is intended for a switch device of modular design. This central module 10 comprises a central base 11 which is surmounted by a front face 18. The front face 18 comprises in particular various control / command members 19 which, for example, allow an operator to control and monitor the switching device. The central base 11 is intended to carry a first switch module, called the central switch module 15 (see figures 2 and 3 ).

Le socle central 11 comporte également un mécanisme d'actionnement central qui est destiné à actionner le module interrupteur central 15 de l'appareil interrupteur, c'est-à-dire à déplacer le contact mobile du module interrupteur central 15 de la position fermée à la position ouverte. Le socle central 11 comporte pour cela une fenêtre centrale 12 de sorte que le mécanisme d'actionnement puisse accéder et commander mécaniquement le contact mobile du module interrupteur central 15 à l'aide de moyens mécaniques classiques, tels que tringles, bielles, pivots et/ou engrenages non représentés sur les figures, mais dont un exemple est décrit notamment dans le document EP1968088 .The central base 11 also comprises a central actuating mechanism which is intended to actuate the central switch module 15 of the switching device, that is to say to move the movable contact of the central switch module 15 from the closed position to the open position. The central base 11 comprises for this a central window 12 so that the actuating mechanism can access and mechanically control the movable contact of the central switch module 15 using conventional mechanical means, such as rods, connecting rods, pivots and / or gears not shown in the figures, but an example of which is described in particular in the document EP1968088 .

Le module central 10 peut également comporter une unité de commande qui, en liaison notamment avec les organes de contrôle/commande 19 de la face avant 18 et/ou avec des organes de contrôle/commande à distance, est en charge de piloter le mécanisme d'actionnement central et de surveiller le fonctionnement de l'appareil interrupteur.The central module 10 can also include a control unit which, in conjunction in particular with the control / command members 19 of the front face 18 and / or with the remote control / command members, is responsible for controlling the mechanism. central actuation and monitor the operation of the switch device.

En référence aux figures 2 et 3, le socle central 11 comporte des moyens de fixation arrière qui sont placés à l'arrière du socle central 11 et qui sont avantageusement aptes à fixer de manière amovible un socle arrière 41 au module central 10, ainsi que des moyens de fixation latéraux placés de chaque côté du socle central 11 et qui sont aptes à fixer de manière amovible deux socles latéraux 21, 31 au module central. Ces moyens de fixation ne sont pas détaillés dans le présent document et peuvent comprendre notamment des vis et écrous. Pour que le mécanisme d'actionnement puisse accéder aux socles latéraux 21, 31 et au socle arrière 41 en vue de commander les contacts mobiles, les moyens de fixation arrière comprennent une trappe arrière 14 placée à l'arrière du socle central 11 et les moyens de fixation latéraux comprennent deux trappes latérales 13 placées de chaque côté du socle central 11.With reference to figures 2 and 3 , the central base 11 comprises rear fixing means which are placed at the rear of the central base 11 and which are advantageously capable of removably fixing a rear base 41 to the central module 10, as well as lateral fixing means placed from each side of the central base 11 and which are capable of removably fixing two side bases 21, 31 to the central module. These fixing means are not detailed in this document and may in particular include screws and nuts. So that the actuating mechanism can access the side bases 21, 31 and the rear base 41 in order to control the movable contacts, the rear fixing means comprise a rear hatch 14 placed at the rear of the central base 11 and the means side mounting brackets include two side hatches 13 placed on each side of the central base 11.

Grâce à l'invention, un même module central 10 est avantageusement utilisable quelle que soit l'architecture de l'appareil interrupteur, c'est-à-dire aussi bien dans une architecture frontale représentée en figure 2, que dans une architecture longitudinale représentée en figure 3. De plus, le mécanisme d'actionnement de ce module central 10 est capable de commander les contacts mobiles de l'ensemble des modules interrupteurs de l'appareil.Thanks to the invention, the same central module 10 can advantageously be used regardless of the architecture of the switch device, that is to say also in a front architecture shown in figure 2 , than in a longitudinal architecture represented in figure 3 . In addition, the actuating mechanism of this central module 10 is capable of controlling the movable contacts of all of the switch modules of the apparatus.

Ainsi, la figure 2 montre un appareil interrupteur ayant une architecture frontale. Il comporte deux socles latéraux 21, 31 qui sont fixés latéralement de chaque côté du socle central 11 du module central 10. Le socle central 11 porte un module interrupteur central 15 et chaque socle latéral 21, 31 porte un module interrupteur latéral 25, 35. Le module interrupteur central 15 et les modules interrupteurs latéraux 25, 35 sont identiques et actionnables par le mécanisme d'actionnement du module central. Les deux trappes latérales 13 présentes de chaque côté du socle central 11 sont placées en vis-à-vis d'une trappe correspondante 23 (voir figures 4a, 4b) sur chaque socle latéral. Chaque socle latéral 21, 31 comporte également une fenêtre 22 (voir figures 4a, 4b) pour que le mécanisme d'actionnement puisse accéder au module interrupteur latéral 25, 35. Les modules latéraux 21 et 31 sont symétriques par rapport à un plan vertical longitudinal de l'appareil.So the figure 2 shows a switch device having a front architecture. It comprises two side bases 21, 31 which are fixed laterally on each side of the central base 11 of the central module 10. The central base 11 carries a central switch module 15 and each side base 21, 31 carries a side switch module 25, 35. The central switch module 15 and the side switch modules 25, 35 are identical and can be actuated by the actuating mechanism of the central module. The two side hatches 13 present on each side of the central base 11 are placed opposite a corresponding hatch 23 (see figures 4a, 4b ) on each side plinth. Each side base 21, 31 also has a window 22 (see figures 4a, 4b ) so that the actuating mechanism can access the side switch module 25, 35. The side modules 21 and 31 are symmetrical with respect to a longitudinal vertical plane of the device.

De même, la figure 3 montre un appareil interrupteur ayant une architecture longitudinale. Il comporte un socle arrière 41 qui est fixé à l'arrière du socle central 11. Le socle central 11 porte un module interrupteur central 15 et le socle arrière 41 porte deux modules interrupteurs arrières 45, 55. Le module interrupteur central 15 et les modules interrupteurs arrières 45, 55 sont identiques et actionnables par le mécanisme d'actionnement du module central. La trappe arrière 14 présente à l'arrière du socle central 11 est placée en vis-à-vis d'une trappe correspondante 44 (voir figures 5a, 5b) sur le socle arrière 41. Le socle arrière 41 comporte également deux fenêtres 42, 52 (voir figures 5a, 5b) pour accéder aux deux modules interrupteurs arrières 45, 55.Likewise, the figure 3 shows a switch device having a longitudinal architecture. It comprises a rear base 41 which is fixed to the rear of the central base 11. The central base 11 carries a central switch module 15 and the rear base 41 carries two rear switch modules 45, 55. The central switch module 15 and the modules rear switches 45, 55 are identical and can be actuated by the actuating mechanism of the central module. The rear hatch 14 present at the rear of the central base 11 is placed opposite a corresponding hatch 44 (see figures 5a , 5b ) on the rear base 41. The rear base 41 also has two windows 42, 52 (see figures 5a , 5b ) to access the two rear switch modules 45, 55.

En résumé, les trappes 13, 14, 23, 44 du socle central et des socles latéraux/arrière puis les fenêtres 12, 22, 42, 52 présentent des ouvertures suffisantes pour transmettre les mouvements du mécanisme d'actionnement central vers les socles latéraux/arrière, puis vers les contacts mobiles des différents modules interrupteurs. Aucune liaison électrique n'est nécessaire entre le socle central 11 et les socles latéraux/arrière 21, 31, 41, ce qui rend la solution très simple à mettre en œuvre. Le socle central 11 doit juste comporter des moyens de transmission des mouvements du mécanisme d'actionnement vers le socle arrière 41 et les socles latéraux 21, 31, lorsque un socle arrière 41 ou deux socles latéraux 21, 31 sont fixés au module central 10, pour pouvoir actionner les autres modules interrupteurs 25, 35, 45, de l'appareil interrupteur à l'aide d'organes mécaniques classiques tels que par exemple tringles, bielles, pivots et/ou engrenages.In summary, the hatches 13, 14, 23, 44 of the central base and the side / rear bases and then the windows 12, 22, 42, 52 have sufficient openings to transmit the movements of the central actuating mechanism to the side bases / rear, then to the moving contacts of the various switch modules. No electrical connection is necessary between the central base 11 and the side / rear bases 21, 31, 41, which makes the solution very simple to implement. The central base 11 must just include means for transmitting the movements of the actuating mechanism to the rear base 41 and the side bases 21, 31, when a rear base 41 or two side bases 21, 31 are fixed to the central module 10, in order to be able to actuate the other switch modules 25, 35, 45, of the switch device using conventional mechanical members such as, for example, rods, connecting rods, pivots and / or gears.

Par ailleurs, tous les modules interrupteurs de l'appareil interrupteur sont fixés de manière amovible sur leur socle respectif. Ainsi, le module interrupteur central 15 est fixé de manière amovible sur le socle central 11 du module central 10, les modules interrupteurs arrières 45, 55 sont fixés de manière amovible sur le socle arrière 41 et les modules interrupteurs latéraux 25, 35 sont fixés de manière amovible sur leur socle latéral 21, 31 respectif, ce qui notamment permet de remplacer facilement un module interrupteur.Furthermore, all the switch modules of the switch device are removably fixed on their respective bases. Thus, the central switch module 15 is removably fixed on the central base 11 of the central module 10, the rear switch modules 45, 55 are removably fixed on the rear base 41 and the side switch modules 25, 35 are fixedly fixed. removable manner on their respective lateral base 21, 31, which in particular makes it possible to easily replace a switch module.

Dans l'architecture de la figure 3, on note que les trappes latérales 13 de chaque côté du socle central 11 sont présentes mais ne sont pas utilisées car il n'y a pas de socle latéral 21, 31 fixé au socle central 11. De même, dans l'architecture de la figure 2, la trappe arrière 14 du socle central 11 est présente mais n'est pas utilisée car il n'y a pas de socle arrière 41 fixé au socle central 11. Pour les masquer, un cache étanche peut alors bien sûr être placé sur les différentes trappes non utilisées.In the architecture of the figure 3 , we note that the side hatches 13 on each side of the central base 11 are present but are not used because there is no side base 21, 31 fixed to the central base 11. Likewise, in the architecture of the figure 2 , the rear hatch 14 of the central base 11 is present but is not used because there is no rear base 41 fixed to the central base 11. To hide them, a waterproof cover can then of course be placed on the different hatches not used.

Selon un mode de réalisation préféré, l'invention prévoit plusieurs types de socles latéraux et socle arrière qui sont utilisables avec un même socle central 10 invariant, de façon à pouvoir construire des appareils interrupteurs de calibres différents (c'est-à-dire travaillant à des intensités nominales différentes) par exemple de 630A à 3150A.According to a preferred embodiment, the invention provides several types of side bases and rear base which can be used with the same invariant central base 10, so as to be able to construct switch devices of different ratings (that is to say working at different nominal currents) for example from 630A to 3150A.

On voit ainsi sur les figures 5a, respectivement 5b, que les deux socles arrière 41, respectivement 41', présentent des distances différentes d1, respectivement d1', entre les axes des deux fenêtres 42, 52. De même, les socles arrière 41, respectivement 41', présentent des distances différentes d2, respectivement d2', entre l'axe de leur première fenêtre 42 et le rebord du côté ayant la trappe 44.We can see on the figures 5a , respectively 5b, that the two rear bases 41, respectively 41 ', have different distances d1, respectively d1', between the axes of the two windows 42, 52. Likewise, the rear bases 41, respectively 41 ', have distances different d2, respectively d2 ', between the axis of their first window 42 and the edge of the side having the hatch 44.

Donc, suivant qu'un module central 10 est utilisé avec un socle arrière 41 ou un socle arrière 41', l'appareil interrupteur aura une distance entre phases différente. Grâce à cela, un même socle central 10 peut servir de base à la construction de plusieurs calibres d'appareils interrupteurs, par exemple un socle arrière de type 41 pour les calibres 630A et 1250A, ou un socle arrière de type 41' pour le calibre allant jusqu'à 3150A, associés à des modules interrupteurs 15, 45, 55 de calibres différents.Therefore, depending on whether a central module 10 is used with a rear base 41 or a rear base 41 ', the switching device will have a different distance between phases. Thanks to this, the same central base 10 can be used as a base for the construction of several calibers of switching devices, for example a rear base of type 41 for calibers 630A and 1250A, or a rear base of type 41 'for caliber. up to 3150A, associated with switch modules 15, 45, 55 of different ratings.

Les distances d1, d2 et d1', d2' sont bien sûr agencées pour que les distances entre phases d'un appareil soient identiques, c'est-à-dire que les distances entre d'une part les modules interrupteurs 45 et 55 et d'autre part les modules interrupteurs 45 et 15 soient identiques.The distances d1, d2 and d1 ', d2' are of course arranged so that the distances between phases of a device are identical, that is to say that the distances between on the one hand the switch modules 45 and 55 and on the other hand, the switch modules 45 and 15 are identical.

Cette caractéristique se retrouve également dans le cas d'une architecture frontale avec la possibilité d'adjoindre différentes tailles de modules latéraux 21, 31 au module central 10. Les figures 4a, 4b montrent ainsi des modules latéraux 21, respectivement 21', qui diffèrent par la distance entre leur fenêtre 22 et le rebord du côté ayant la trappe 23. Ceci permet d'avoir une distance entre phases plus importante dans le cas des modules latéraux 21'. Grâce à cela, un même socle central 10 peut servir de base à la construction de plusieurs calibres d'appareils interrupteurs, par exemple des socles latéraux de type 21 pour les calibres 630A et 1250A, et des socles latéraux de type 21' pour les calibres jusqu'à 3150A, associés à des modules interrupteurs 15, 25, 35 de calibres différents.This characteristic is also found in the case of a front architecture with the possibility of adding different sizes of side modules 21, 31 to the central module 10. figures 4a, 4b thus show side modules 21, respectively 21 ′, which differ in the distance between their window 22 and the rim on the side having the hatch 23. This makes it possible to have a greater distance between phases in the case of side modules 21 ′. Thanks to this, a single central base 10 can be used as a base for the construction of several ratings of switching devices, for example side bases of type 21 for ratings 630A and 1250A, and side bases of type 21 'for ratings up to 3150A, associated with switch modules 15, 25, 35 of different ratings.

Selon une autre caractéristique préférée, l'invention prévoit également de pouvoir facilement ajouter un rehausseur 17 entre chaque socle et son module interrupteur associé. Le fait de surmonter un module interrupteur par rapport à son socle permet avantageusement de supporter des tensions nominales plus importantes, tout en n'augmentant pas les contraintes diélectriques. La figure 6 montre ainsi l'appareil interrupteur de la figure 3 dans lequel un rehausseur 17 a été ajouté pour chaque module interrupteur 15, 35, 45. Bien sûr, un rehausseur similaire aurait pu être ajouté dans l'exemple de la figure 2.According to another preferred characteristic, the invention also provides for being able to easily add a booster 17 between each base and its associated switch module. The fact of overcoming a switch module with respect to its base advantageously makes it possible to withstand higher nominal voltages, while not increasing the dielectric stresses. The figure 6 thus shows the device switch of the figure 3 in which a booster 17 has been added for each switch module 15, 35, 45. Of course, a similar booster could have been added in the example of figure 2 .

Un tel rehausseur peut par exemple avoir une hauteur d'environ 80 à 100 mm avec une partie en élastomère pour assurer l'étanchéité des pôles. Il est utilisé par exemple pour pouvoir passer d'une tension nominale de 17,5kV à 24kV.Such a booster can for example have a height of approximately 80 to 100 mm with an elastomer part to ensure the sealing of the poles. It is used for example to be able to go from a nominal voltage of 17.5kV to 24kV.

Avantageusement, ces deux caractéristiques peuvent être utilisées indépendamment l'une de l'autre, à savoir utiliser un rehausseur pour supporter une tension nominale plus importante et/ou utiliser des socles latéraux/arrière avec des distances entre phases plus importantes pour supporter une plus forte intensité nominale.Advantageously, these two characteristics can be used independently of one another, namely to use a booster to support a higher nominal voltage and / or to use side / rear bases with greater distances between phases to support a greater nominal current.

Les figures 7 et 8 montrent une version débrochable de l'invention dans l'une et l'autre des architectures présentées. Un module central est en effet destiné à être placé sur un chariot mobile (truck en anglais) de façon à pouvoir approcher puis raccorder électriquement l'appareil interrupteur à l'intérieur d'une cellule haute tension. Le chariot mobile est mobile en translation pour pouvoir approcher l'appareil interrupteur et comporte en plus un moyen d'entrainement classique, par exemple une vis sans fin qui est motorisable ou actionnable par manivelle pour le raccordement de l'appareil interrupteur. D'habitude, un chariot mobile comporte un plateau sur lequel l'appareil interrupteur est fixé et dont les dimensions sont donc adaptées à cet appareil interrupteur. Le plateau comporte par exemple des roues pour pouvoir déplacer le chariot facilement.The figures 7 and 8 show a withdrawable version of the invention in one and the other of the architectures presented. A central module is in fact intended to be placed on a mobile truck so as to be able to approach and then electrically connect the switch device inside a high voltage cell. The mobile carriage is movable in translation so as to be able to approach the switching device and further comprises a conventional drive means, for example an endless screw which can be motorized or actuated by a crank for connecting the switching device. Usually, a mobile trolley comprises a plate on which the switching device is fixed and the dimensions of which are therefore adapted to this switching device. The plate comprises, for example, wheels in order to be able to move the trolley easily.

Or, dans le cas de l'architecture modulaire de l'invention, il est plus difficile de prévoir et d'adapter les dimensions d'un tel plateau vu les différents encombrements de l'appareil interrupteur en fonction de l'architecture choisie lors du montage. C'est pourquoi un chariot mobile 16 est directement fixé sous le module central 10 de l'appareil interrupteur mais vu que soit deux socles latéraux 21, 31, soit un socle arrière 41, sont assemblés au socle central 11 du module central, il convient d'assurer la stabilité et le bon déplacement de l'appareil interrupteur. Pour cela, l'invention prévoit, dans le cadre de l'architecture longitudinale de la figure 8, de pouvoir ajouter deux roulettes 46 qui sont placées sur chacun des côtés latéraux du socle arrière 41. De même, dans le cadre de l'architecture frontale de la figure 7, l'invention prévoit de pouvoir ajouter deux roulettes 26 qui sont placées sur le côté extérieur du socle latéral 21 (c'est-à-dire sur le côté latéral non fixé au socle central 11) et deux roulettes sur le côté extérieur du socle latéral 31 (non représentées). Ainsi, dans les deux architectures, il y a quatre roulettes qui facilitent le déplacement du chariot 16 et de l'appareil interrupteur et assurent la stabilité de l'ensemble. Elles peuvent par exemple être guidées dans des rails présents dans la cellule haute tension. Ces différentes roulettes sont facilement montées sur les socles lors du montage de l'appareil interrupteur.However, in the case of the modular architecture of the invention, it is more difficult to plan and adapt the dimensions of such a plate given the different dimensions of the switch device according to the architecture chosen during the installation. mounting. This is why a mobile trolley 16 is directly fixed under the central module 10 of the switching device but given that either two side bases 21, 31, or a rear base 41, are assembled to the central base 11 of the central module, it is necessary ensure the stability and the correct movement of the switching device. For this, the invention provides, within the framework of the longitudinal architecture of the figure 8 , to be able to add two casters 46 which are placed on each of the lateral sides of the rear base 41. Likewise, as part of the front architecture of the figure 7 , the invention provides for being able to add two casters 26 which are placed on the outer side of the lateral base 21 (that is to say on the lateral side not fixed to the central base 11) and two castors on the outer side of the base lateral 31 (not shown). Thus, in both architectures, there are four casters which facilitate the movement of the carriage 16 and of the switching device and ensure the stability of the assembly. They can for example be guided in rails present in the high voltage cell. These different castors are easily mounted on the bases during the assembly of the switch device.
