Description

L'invention se rapporte à un appareillage électrique de coupure multipolaire, et en particulier à un appareillage de coupure multipolaire comportant des ampoules à vide.The invention relates to an electrical switchgear device multipole, and in particular to a multipole breaking apparatus comprising vacuum ampoules.

Le document EP 0 346 603 décrit un appareillage électrique de coupure tripolaire comportant trois modules polaires de coupure identiques disposés côte à côte sur un châssis. Chaque module comporte une ampoule à vide munie d'une tige de commande mobile en translation. Un mécanisme d'entraînement à ressort de type connu comportant un arbre des pôles, permet l'entraînement des tiges de commande des trois ampoules à vide. Chaque tige de commande est reliée à l'arbre des pôles par l'intermédiaire d'une tringlerie indépendante, propre au module de coupure correspondant. Cette tringlerie est composée d'un levier de transmission, disposé entre deux bielles, l'une des bielles reliant le levier à une manivelle de l'arbre des pôles et l'autre reliant le levier à la tige de commande de l'ampoule à vide. En pratique, les ampoules à vide des différents pôles sont susceptibles d'être soumises, lors de l'ouverture comme de la fermeture, à des efforts différents. Lors de l'ouverture, il peut arriver que les contacts d'une ampoule soient légèrement soudés, ou bien au contraire que les efforts électromagnétiques induits par les courants sur les contacts tendent à séparer plus violemment les contacts de l'une des ampoules. Lors de la fermeture, notamment si celle-ci a lieu sur un court-circuit pour l'un des pôles, l'un des contacts peut être soumis à des efforts de répulsion très importants. Du fait de ces sollicitations différentes sur les tiges des ampoules à vide des différents pôles, l'arbre des pôles se trouve soumis à des contraintes de torsion importantes, directement transmises par les tringleries indépendantes des différents pôles. Il existe alors un risque de déformation dynamique en torsion importante de l'arbre des pôles, qui a pour conséquence une fermeture ou une ouverture non simultanée des différentes ampoules. Pour pallier ce risque, il est alors nécessaire de surdimensionner l'arbre des pôles, de manière à lui conférer une rigidité supplémentaire en torsion. Par ailleurs, l'appareillage ne permet pas de faire varier facilement l'espacement entre les ampoules à vide des différents pôles. Il est vrai que la construction en modules de coupure identiques et indépendants permettrait théoriquement toute disposition arbitraire. Toutefois, à chaque distance entre pôles correspond un arbre des pôles différent, puisque les manivelles de l'arbre des pôles doivent être espacées de la même distance les unes des autres que les ampoules. Or, l'arbre des pôles est une pièce particulièrement onéreuse, d'autant plus que sa rigidité en torsion est critique. De plus, la nécessité de prévoir des arbres des pôles différents pour chaque entraxe interdit de concevoir le mécanisme comme une unité fonctionnelle prémontée en usine indépendamment des modules de coupure. L'architecture ne favorise guère la différenciation retardée des différents modèles d'une gamme d'appareillages de coupure.The document EP 0 346 603 discloses a three-pole switchgear with three identical polar break modules arranged side by side on a chassis. Each module comprises a vacuum bulb provided with a movable control rod in translation. A spring drive mechanism of known type having a pole shaft, allows the driving of the control rods of the three vacuum bulbs. Each control rod is connected to the pole shaft via an independent linkage, specific to the corresponding cut-off module. This linkage consists of a transmission lever, arranged between two connecting rods, one of the connecting rods connecting the lever to a crank of the pole shaft and the other connecting the lever to the control rod of the bulb to empty. In practice, the vacuum bulbs of the different poles are likely to be subjected, during opening and closing, to different forces. When opening, it may happen that the contacts of a bulb are slightly welded, or on the contrary that the electromagnetic forces induced by the currents on the contacts tend to separate more violently the contacts of one of the bulbs. When closing, especially if it occurs on a short circuit for one of the poles, one of the contacts may be subjected to very large repulsion efforts. Because of these different stresses on the rods of the vacuum bulbs of the various poles, the pole shaft is subjected to significant torsional stresses, directly transmitted by the independent linkages of the different poles. There is then a risk of dynamic deformation in significant torsion of the pole shaft, which results in closure or non-simultaneous opening of different bulbs. To overcome this risk, it is then necessary to oversize the pole shaft, so as to give it additional torsional stiffness. Furthermore, the apparatus does not allow to easily vary the spacing between the vacuum bulbs of the different poles. It is true that the construction of identical and independent clipping modules theoretically allows any arbitrary provision. However, at each distance between poles corresponds to a different pole shaft, since the cranks of the pole shaft must be spaced the same distance from each other as the bulbs. However, the pole shaft is a particularly expensive part, especially since its torsional rigidity is critical. In addition, the need to provide shafts of different poles for each center distance prohibits to design the mechanism as a functional unit pre-assembled at the factory independently of the cutoff modules. The architecture does not favor the delayed differentiation of the different models of a range of switchgear.

Un autre objectif est de réaliser un appareillage dans lequel les modules de coupure peuvent être prémontés et essayés en usine, avant leur montage avec le mécanisme et la bielle de manière à améliorer la différenciation retardée.
Un autre objectif est d'accroître la modularité d'un appareillage de coupure multipolaire à modules de coupure polaires indépendants, en permettant à faible coût de changer la distance entre pôles.An object of the invention is to provide a multipole electrical switchgear of simple design comprising a rigid support for the various parts of the apparatus.

En référence aux figures 1 et 2, un appareillage de coupure tripolaire 10 est composé d'un mécanisme d'entraînement 12 et de trois modules de coupure identiques 14, 16, 18, disposés côte à côte d'un même côté d'une cloison 20 les séparant du mécanisme d'entraînement 12. La cloison 20 est constituée par une tôle comportant trois fenêtres 22, 24, 26 et repose sur une deuxième tôle 28 disposée en équerre et faisant office de socle. La cloison 20 est au potentiel de la terre et assure la protection électrique des personnes.With reference to figures 1 and 2 , a tripolar switchgear 10 is composed of a drive mechanism 12 and three identical cutoff modules 14, 16, 18, arranged side by side on the same side of a partition 20 separating them from the drive mechanism. 12. The partition 20 is constituted by a sheet having three windows 22, 24, 26 and rests on a second plate 28 arranged at right angles and acting as a base. The partition 20 is at ground potential and provides electrical protection to people.

Le mécanisme d'entraînement 12 peut être de tout type connu comportant un arbre des pôles. Il peut s'agir par exemple d'un mécanisme du type décrit dans le document EP-A- 0 222 645 , muni d'un sous-ensemble d'armement et de fermeture comportant un ressort de fermeture, et d'un sous-ensemble d'ouverture comportant un ressort d'ouverture. L'essentiel dans le cadre la présente invention est que le mécanisme comporte un arbre de sortie, dit encore arbre des pôles. Dans l'exemple de réalisation, le mécanisme 12 est fixé sur un châssis de support 30 et muni d'un arbre des pôles 32 supporté par des paliers 34 fixés au châssis 30. Le châssis est lui-même fixé à la cloison 20.The drive mechanism 12 may be of any known type having a pole shaft.

In the exemplary embodiment, the mechanism 12 is fixed on a support frame 30 and provided with a pole shaft 32 supported by bearings 34 fixed to the frame 30. The frame is itself fixed to the partition 20.

Comme l'illustre la figure 3, l'arbre des pôles 32 comporte deux manivelles doubles 36, 38 qui traversent la paroi du châssis par des lumières et permettent l'articulation entre l'arbre des pôles 32 et une bielle de transmission 40.

Chaque bras en vé 42, 44 supporte, à son extrémité convergente, une paire de pattes 50, 52 munies d'alésages coaxiaux, formant des paliers. Les manivelles 36, 38 comportent également des alésages coaxiaux formant paliers, de sorte qu'une liaison pivotante de type charnière est obtenue entre les manivelles doubles 36, 38 de l'arbre des pôles 32 et la bielle 40 par insertion d'axes 54 dans les alésages correspondants des manivelles doubles 36, 38 et des pattes doubles 50, 52.

Ces pattes permettent, par insertion d'axes 66, une liaison type charnière avec trois leviers doubles 70, 72, 74 appartenant aux trois modules polaires 14, 16, 18 de l'appareillage, qui traversent les fenêtres 22, 24, 26 de la cloison 20.As illustrated by figure 3 , the pole shaft 32 comprises two double cranks 36, 38 which pass through the wall of the chassis through slots and allow the articulation between the shaft of the poles 32 and a transmission rod 40. The transmission rod 40 is constituted by a flat part forming two double vee arms 42, 44, spaced from one another, and connected on the diverging end side by a base 46. Each vee arm 42, 44 supports, at its convergent end, a pair of lugs 50, 52 provided with coaxial bores, forming bearings. The cranks 36, 38 also comprise coaxial bores forming bearings, so that a hinge-type pivot connection is obtained between the double cranks 36, 38 of the pole shaft 32 and the rod 40 by insertion of pins 54 into each other. the corresponding bores of the double cranks 36, 38 and double tabs 50, 52. The base 46 supports three pairs of tabs 60, 62, 64 provided with coaxial bores, forming bearings. These tabs allow, by insertion of axes 66, a hinge type connection with three double levers 70, 72, 74 belonging to the three polar modules 14, 16, 18 of the apparatus, which pass through the windows 22, 24, 26 of the partition 20.

Les trois modules de coupure étant identiques, seul le module 18 sera décrit. Comme l'illustre la figure 2, le module 18 comporte une ampoule à vide 80 supportée par un bâti 82. Le bâti 82 est fixé à la paroi 20 et au socle 28, de sorte que le châssis 30, les tôles 20, 28 et les bâtis 82 des trois pôles forment ensemble un support 83 pour les autres pièces de l'appareillage. Deux plages de raccordement 84, 86, fixées au bâti 82, sont destinées à raccorder électriquement l'ampoule 80 à un jeu de barres (non représenté). On désigne ici par l'expression générique d'ampoule à vide un sous-ensemble de type connu, comportant un corps cylindrique 88 formant une enceinte où règne un vide relatif et qui renferme une paire de contacts séparables 90, 92 reliés aux plages de raccordement 84, 86. Le corps 88 est lui-même divisé en un tronçon isolateur médian 94 en matériau isolant, un premier tronçon d'extrémité métallique constituant un premier flasque de fermeture 96, et un deuxième tronçon d'extrémité métallique constituant un deuxième flasque de fermeture 98. Le contact 92 est fixe et relié au deuxième flasque 98. L'autre contact 90 constitue une extrémité axiale d'une tige 100 mobile en translation le long de son axe et traversant le corps 88 de l'ampoule par un orifice du flasque 96. Un soufflet d'étanchéité 102 brasé sur la tige 100 et sur la paroi interne du premier flasque 96, permet un mouvement axial de translation de la tige 100 et du contact mobile 90 par rapport au contact fixe 92, tout en préservant le vide régnant dans l'enceinte. Le raccordement électrique de la tige 100 au jeu de barres est assuré au moyen d'une liaison électrique flexible 104 dont une extrémité constitue également la plage de raccordement 84.The three cutoff modules being identical, only the module 18 will be described. As illustrated by figure 2 , the module 18 comprises a vacuum interrupter 80 supported by a frame 82. The frame 82 is fixed to the wall 20 and the base 28, so that the frame 30, the plates 20, 28 and the frames 82 of the three poles form together a support 83 for the other parts of the apparatus. Two connection pads 84, 86, fixed to the frame 82, are intended to electrically connect the lamp 80 to a busbar (not shown). Here, the generic expression of a vacuum bulb designates a subset of known type, comprising a cylindrical body 88 forming a chamber in which there is a relative vacuum and which encloses a pair of separable contacts 90, 92 connected to the connection pads. 84, 86. The body 88 is itself divided into a medial insulating section 94 of insulating material, a first metal end section constituting a first closure flange 96, and a second metal end section constituting a second flange of closing 98. The contact 92 is fixed and connected to the second flange 98. The other contact 90 constitutes an axial end of a rod 100 movable in translation along its axis and through the body 88 of the bulb through an orifice of the flange 96. A sealing bellows 102 brazed on the rod 100 and on the inner wall of the first flange 96, allows an axial translational movement of the rod 100 and the movable contact 90 relative to the con fixed tact 92, while preserving the vacuum prevailing in the enclosure. The electrical connection of the rod 100 to the busbar is ensured by means of a flexible electrical connection 104, one end of which also constitutes the connection pad 84.

A l'extérieur de l'enceinte, la tige 100 est reliée au levier double 74, par l'intermédiaire d'un bras isolant 110. Le bras isolant comporte un corps en matière plastique 112 surmoulant d'une part la tête d'une première tige filetée 114, et d'autre part la tête d'une deuxième tige filetée 116 située dans le prolongement axial de la première. La première tige filetée 114 est vissée dans un trou borgne taraudé situé à l'extrémité de la tige 100 de l'ampoule 80. Sur la deuxième tige filetée 116 est vissé un écrou tubulaire 118 de réglage. L'écrou 118 supporte à une extrémité une assiette de support 120 pour une extrémité d'un ressort de pression de contact 122. L'autre extrémité du ressort 122 porte sur une deuxième assiette 124, qui repose sur un barreau 126. Le barreau comporte un alésage 128 formant un fourreau de guidage traversé par l'écrou tubulaire 118. Le barreau 126 tourillonne librement dans des axes latéraux 130 supportés par les bras du levier 74. Le fourreau de guidage 128 autorise à la fois la translation de l'écrou 118 parallèlement à son axe et sa libre rotation. L'écrou 118 comporte un épaulement qui vient reposer sur la partie barreau 126 opposée à la deuxième assiette 124. Les deux bras du levier double 74 pivotent autour d'un axe 132 supporté par le bâti 82. Les trois modules de coupure 14, 16, 18 de l'appareillage 10 étant disposés côte à côte, les axes de pivotement 132 des leviers 70, 72, 74 sont alignés, et parallèles à l'arbre des pôles 32. Les leviers 70, 72, 74 sont parallèles.Outside the enclosure, the rod 100 is connected to the double lever 74, via an insulating arm 110. The insulating arm comprises a plastic body 112 overmolding on the one hand the head of a first threaded rod 114, and secondly the head of a second threaded rod 116 located in the axial extension of the first. The first threaded rod 114 is screwed into a threaded blind hole located at the end of the rod 100 of the bulb 80. On the second threaded rod 116 is screwed a tubular adjusting nut 118. The nut 118 supports at one end a support plate 120 for one end of a contact pressure spring 122. The other end of the spring 122 bears on a second plate 124, which rests on a bar 126. The bar comprises a bore 128 forming a guide sleeve traversed by the tubular nut 118. The bar 126 freely journalled in lateral axes 130 supported by the arms of the lever 74. The sheath guide 128 allows both the translation of the nut 118 parallel to its axis and its free rotation. The nut 118 has a shoulder that rests on the bar portion 126 opposite to the second plate 124. The two arms of the double lever 74 pivot about an axis 132 supported by the frame 82. The three breaking modules 14, 16 , 18 of the apparatus 10 being arranged side by side, the pivot axes 132 of the levers 70, 72, 74 are aligned, and parallel to the pole shaft 32. The levers 70, 72, 74 are parallel.

Ainsi, la chaîne cinématique reliant l'arbre des pôles 32 aux tiges 100 des trois modules de coupure 14, 16, 18 comporte une bielle unique 40 de liaison entre l'arbre de pôles 32 et les trois leviers doubles 70, 72, 74 des modules de coupure, et est prolongé dans chaque module par un isolant 112, dont une extrémité coulisse dans un fourreau 128 tourillonnant par rapport au levier double 70, 72, 74, et l'autre extrémité est solidaire de la tige 100 de l'ampoule 80. Cette chaîne cinématique permet de définir cinq axes géométriques de rotation parallèle : un premier axe géométrique 140 de pivotement de l'arbre des pôles, un deuxième axe géométrique 142 de pivotement des leviers 70, 72, 74, un troisième axe géométrique 144 de pivotement de la bielle par rapport aux manivelles de l'arbre des pôles, un quatrième axe géométrique 146 de pivotement de la bielle par rapport aux leviers, et un cinquième axe géométrique 148 de pivotement des barreaux 126 par rapport aux leviers 70, 72, 74. Le premier axe 140 et le deuxième axe 142 sont tout deux fixes par rapport au support 83, les autres axes étant mobile pendant les séquences d'ouverture et de fermeture.Thus, the kinematic chain connecting the shaft of the poles 32 to the rods 100 of the three breaking modules 14, 16, 18 comprises a single connecting rod 40 connecting the pole shaft 32 and the three double levers 70, 72, 74 of the cutoff modules, and is extended in each module by an insulator 112, one end slides in a sheath 128 pivoting relative to the double lever 70, 72, 74, and the other end is integral with the rod 100 of the bulb 80. This kinematic chain makes it possible to define five geometrical axes of parallel rotation: a first geometric axis 140 of pivoting of the pole shaft, a second geometric axis 142 of pivoting of the levers 70, 72, 74, a third geometric axis 144 of pivoting of the connecting rod relative to the cranks of the pole shaft, a fourth geometric axis 146 pivoting the rod relative to the levers, and a fifth geometric axis 148 of pivoting bars 126 relative to the levers 70, 72, 74. The first axis 140 and the second axis 142 are both fixed relative to the support 83, the other axes being movable during the opening and closing sequences.

En toute rigueur, le mouvement imprimé à la tige 100 de l'ampoule 80 par ce mécanisme en l'absence de jeu entre les pièces mobiles ne serait pas parfaitement rectiligne par rapport au bâti 82. Toutefois, l'angle entre le levier 70, 72, 74 et la tige 100 est toujours très proche de l'angle droit, et la course de la tige 100 de l'ampoule entre sa position d'ouverture et sa position de fermeture ne dépasse pas quelques millimètres, ce qui correspond à un angle de rotation du levier ne dépassant pas quelques degrés, de sorte qu'en l'absence de jeu, le débattement radial de la tige 100 serait de l'ordre du centième de sa course axiale. Dans le mode de réalisation décrit, ce débattement est absorbé par les jeux existants entre les divers éléments de la chaîne cinématique, notamment au niveau des axes 130, 132. Toutefois, si l'on souhaitait une course plus importante, il serait possible de guider le barreau 126 dans un oblong du levier 90, 92, 94.Strictly speaking, the movement printed on the rod 100 of the bulb 80 by this mechanism in the absence of play between the moving parts would not be perfectly rectilinear with respect to the frame 82. However, the angle between the lever 70, 72, 74 and the rod 100 is always very close to the right angle, and the stroke of the rod 100 of the bulb between its open position and its closed position does not exceed a few millimeters, which corresponds to a rotation angle of the lever not exceeding a few degrees, so that in the absence of play, the radial movement of the rod 100 would be of the order of one hundredth of its axial stroke. In the embodiment described, this clearance is absorbed by the existing gaps between the various elements of the driveline, in particular at the axes 130, 132. However, if one wanted a larger race, it would be possible to guide the bar 126 in an oblong of the lever 90, 92, 94.

La chaîne cinématique fonctionne de la manière suivante. Lorsque les contacts sont séparés et le mécanisme ouvert, la chaîne cinématique se trouve initialement dans la position représentée sur la figure 2. A la fermeture, le ressort de fermeture du mécanisme 12 entraîne l'arbre des pôles 32 dans le sens inverse des aiguilles d'une montre, sur une course de plus de 50°. La bielle 40 transmet ce mouvement de manière uniforme aux trois leviers doubles 70, 72, 74. Dans chacun des modules de coupure, le levier double pivote dans le sens des aiguilles d'une montre autour de l'axe 132, entraînant le barreau 126 qui comprime le ressort 122 par l'intermédiaire de l'assiette 124. L'effort de fermeture est ensuite transmis par le ressort 122 au contact mobile 90, par l'intermédiaire de l'assiette 120, de l'écrou 118 et du bras isolant 110. La chaîne cinématique se retrouve dans la position fermée de la figure 4, les contacts étant fermés.The driveline operates in the following manner. When the contacts are separated and the mechanism is open, the kinematic chain is initially in the position shown in FIG. figure 2 . On closing, the closing spring of the mechanism 12 drives the pole shaft 32 in the opposite direction of the clockwise, over a stroke of more than 50 °. The connecting rod 40 transmits this movement uniformly to the three double levers 70, 72, 74. In each of the breaking modules, the double lever pivots clockwise about the axis 132, driving the bar 126 which compresses the spring 122 through the plate 124. The closing force is then transmitted by the spring 122 to the movable contact 90, via the plate 120, the nut 118 and the arm 110. The kinematic chain is in the closed position of the figure 4 , the contacts being closed.

A l'ouverture, le ressort d'ouverture du mécanisme 12 entraîne l'arbre des pôles dans le sens des aiguilles d'une montre, sur une course de plus de 50°. La bielle 40 transmet ce mouvement de manière uniforme aux trois leviers doubles 70, 72, 74. Dans chacun des modules de coupure, le levier double pivote dans le sens contraire des aiguilles d'une montre autour de l'axe 132 sur la figure 4, entraînant directement le barreau 126, l'écrou 118, le bras isolant 110 et la tige 100 du contact mobile, jusqu'à atteindre la position ouverte de la figure 2.On opening, the opening spring of the mechanism 12 drives the pole shaft clockwise over a travel of more than 50 °. The connecting rod 40 transmits this movement uniformly to the three double levers 70, 72, 74. In each of the breaking modules, the double lever pivots counterclockwise about the axis 132 on the figure 4 , directly driving the bar 126, the nut 118, the insulating arm 110 and the rod 100 of the movable contact, until reaching the open position of the figure 2 .

La bielle unique 40 possède un moment quadratique élevé par rapport à un axe perpendiculaire au plan géométrique contenant les axes de pivotement de la bielle par rapport à l'arbre des pôles et aux leviers doubles. Bien que la structure de la bielle ait été allégée pour diminuer sa masse, la base 46 préserve la rigidité recherchée. En d'autres termes, les efforts appliqués à la bielle dans son plan ne sont pas susceptibles d'induire une flexion notable de la bielle. Par conséquent, la bielle 40 confère à la chaîne cinématique une grande rigidité, de sorte que même si les efforts à appliquer aux différentes ampoules sont différents, leur mouvement sera néanmoins simultané. Par construction, l'arbre des pôles 32 est lui-même très rigide en torsion, de sorte qu'il est possible d'espacer les deux charnières joignant la bielle 40 à l'arbre des pôles 32 ce qui contribue à renforcer encore la rigidité de la chaîne cinématique.The single rod 40 has a high quadratic moment with respect to an axis perpendicular to the geometric plane containing the axes of pivoting of the connecting rod with respect to the pole shaft and the double levers. Although the structure of the connecting rod has been lightened to reduce its mass, the base 46 preserves the desired rigidity. In other words, the forces applied to the rod in its plane are not likely to induce a significant bending of the connecting rod. Therefore, the link 40 gives the kinematic chain a high rigidity, so that even if the forces to be applied to different bulbs are different, their movement will nevertheless be simultaneous. By construction, the pole shaft 32 itself is very torsionally rigid, so that it is possible to space the two hinges connecting the connecting rod 40 to the pole shaft 32 which contributes to further reinforce the rigidity of the kinematic chain.

La bielle est fabriquée par découpe d'une tôle. Les leviers sont également réalisés en tôle. L'isolation électrique est réalisée dans chaque module de coupure grâce aux bras isolants. Il est à noter que la partie isolante 112 du bras est conformée en jupe de manière à assurer une isolation optimale.The connecting rod is manufactured by cutting a sheet. The levers are also made of sheet metal. The electrical insulation is carried out in each breaking module thanks to the insulating arms. It should be noted that the insulating portion 112 of the arm is skirted so as to provide optimum insulation.

Pour modifier l'entraxe des modules polaires, il suffit de changer la bielle et, le cas échéant, la paroi 20, qui sont des pièces à très faible coût. Chaque bielle spécifique a une base de longueur différente et surtout des pattes 60, 62, 64 en nombre et emplacements variables. Par contre, la distance entre les pattes 50, 52 assurant la liaison charnière avec les manivelles de l'arbre des pôles reste constante. Ainsi, l'arbre des pôles 32 reste identique quel que soit l'entraxe des modules polaires, ce qui signifie que le mécanisme 12 peut être prémonté en usine et forme une unité fonctionnelle pour l'ensemble de la gamme. De même, les modules de coupure 14, 16, 18 sont identiques, quel que soit l'entraxe choisi. Ceci permet de différer le montage de l'appareillage jusqu'à ce que le choix du client soit arrêté.To change the spacing of the polar modules, simply change the connecting rod and, if necessary, the wall 20, which are very low cost parts. Each specific link has a base of different length and especially legs 60, 62, 64 in number and variable locations. By against the distance between the tabs 50, 52 ensuring the hinge connection with the cranks of the pole shaft remains constant. Thus, the pole shaft 32 remains identical regardless of the spacing between the polar modules, which means that the mechanism 12 can be pre-assembled at the factory and forms a functional unit for the entire range. Similarly, the cutoff modules 14, 16, 18 are identical, regardless of the chosen spacing. This makes it possible to defer fitting of the equipment until the choice of the customer is stopped.

Naturellement, diverses modifications sont possibles. Le nombre de modules n'est pas limité à trois : l'invention s'applique également à des appareillages dipolaires, quadripolaires, voire hexapolaires ou octopolaires. Les leviers 70, 72, 74 peuvent être simples. Le mécanisme d'entraînement peut être de tout type : à ressorts de fermeture et d'ouverture distincts, pour permettre une séquence fermeture, armement, ouverture, fermeture, ouverture ; à un seul ressort permettant la fermeture et l'ouverture.Naturally, various modifications are possible. The number of modules is not limited to three: the invention also applies to dipole devices, quadrupole, or hexapole or octopole. The levers 70, 72, 74 may be simple. The drive mechanism can be of any type: with closing springs and distinct opening, to allow a sequence closing, arming, opening, closing, opening; single spring for closing and opening.
