Description

La présente invention se rapporte à un appareil électrique interrupteur basse tension, en particulier du type contacteur, disjoncteur ou contacteur-disjoncteur, comportant un boîtier de coupure composé de deux parties, chaque partie formant un caisson entourant des blocs ailettes d'extinction d'arc pour une meilleure rigidité et une meilleure résistance à la pression des gaz. L'invention concerne aussi une méthode d'assemblage d'un tel appareil interrupteur.The present invention relates to a low-voltage switchgear electrical apparatus, in particular of the contactor, circuit breaker or contactor-breaker type, comprising a breaking box composed of two parts, each part forming a box surrounding arc-extinguishing fan units. for better rigidity and better resistance to gas pressure. The invention also relates to a method of assembling such a switch device.

Il existe des appareils électriques interrupteurs qui comportent des chambres de coupure dans lesquelles des ailettes d'extinction d'arc permettent de dissiper et d'évacuer le plus rapidement possible l'arc électrique survenant au moment d'une ouverture entre deux contacts. En particulier dans un appareil destiné à la protection contre les courants de court-circuit, ces chambre de coupure doivent pouvoir supporter les arcs électriques importants ainsi que les fortes surpressions des gaz apparaissant en aval des arcs électriques. Les chambres de coupure sont incorporées dans un boîtier de l'appareil interrupteur dont les parois doivent donc être capables de résister à ces surpressions générées au moment de la séparation des contacts de pôles.There are electrical switchgear devices which have breaking chambers in which arc extinguishing vanes make it possible to dissipate and evacuate as quickly as possible the electric arc occurring at the time of an opening between two contacts. In particular in an apparatus for protection against short-circuit currents, these interrupting chambers must be able to withstand the large electric arcs as well as the high overpressures of the gases appearing downstream of the electric arcs. The breaking chambers are incorporated in a housing of the switch device whose walls must therefore be able to withstand these overpressures generated at the time of separation of the pole contacts.

Habituellement, l'appareil interrupteur comporte un boîtier en matériau isolant avec un socle en forme de cuve dont le fond constitue une face arrière de l'appareil interrupteur. La cuve est ouverte sur le devant de telle sorte que les constituants des ensembles polaires de coupure (c'est-à-dire par exemple : pont de contact mobile, poussoir d'actionnement du pont, ressort de pression de contact, cage de maintien du pont, blocs ailettes d'extinction d'arc, déflecteurs, etc...) peuvent être introduits à l'intérieur de la cuve par l'avant.Usually, the switch device comprises a housing made of insulating material with a tank-shaped base whose bottom constitutes a rear face of the switch device. The tank is open on the front so that the constituents of polar cutoff assemblies (that is to say for example: movable contact bridge, bridge actuator, contact pressure spring, holding cage the bridge, arc extinction fins, baffles, etc ...) can be introduced inside the tank from the front.

D'ordinaire, pour faciliter le montage de l'appareil, les ensembles polaires de coupure sont complètement ou partiellement assemblés préalablement à leur introduction dans la cuve. La cuve est ensuite recouverte par un couvercle ou capot assurant notamment l'étanchéité et formant ainsi un boîtier de coupure divisé en plusieurs chambres de coupure pour les différents pôles de puissance de l'appareil interrupteur. Le couvercle porte en outre le système de déclenchement qui est susceptible d'actionner les contacts mobiles de l'appareil. Ce système de déclenchement peut être constitué par exemple d'un bloc serrure mécanique, d'un bloc coupure magnétique et/ou d'un bloc coupure thermique.Usually, to facilitate assembly of the apparatus, the polar cutoff assemblies are completely or partially assembled prior to their introduction into the tank. The tank is then covered by a cover or cover ensuring in particular the sealing and thus forming a breaking box divided into several breaking chambers for the various power poles of the apparatus light switch. The cover also carries the trigger system which is capable of actuating the movable contacts of the apparatus. This trigger system may consist for example of a mechanical lock block, a magnetic break block and / or a thermal cut-off block.

La jonction entre la cuve et le couvercle doit être étudiée avec soin car elle est soumise à de fortes contraintes liées à la surpression des gaz en particulier au voisinage de l'extrémité externe des blocs ailettes, correspondant à la zone où la surpression des gaz est importante. Or, dans une configuration habituelle, l'ouverture de la cuve du boîtier de coupure, et donc la zone de jonction entre la cuve et le couvercle, s'étend sur pratiquement toute la face avant de la cuve, sinon il serait difficile d'insérer dans le boîtier de coupure les différents constituants des ensembles polaires de coupure, surtout lorsqu'ils sont préalablement assemblés. En conséquence, La surface occupée par cette zone de jonction est importante et s'étend y compris au voisinage de l'extrémité des blocs ailettes. Cela entraîne des efforts importants dus à la pression qui occasionnent une fragilité mécanique du boîtier de coupure laquelle doit être compensée notamment par des dispositifs de fixation conséquents pour maintenir une bonne étanchéité entre cuve et couvercle.The junction between the tank and the lid must be studied carefully because it is subjected to high stresses related to the gas overpressure, particularly in the vicinity of the outer end of the fin blocks, corresponding to the zone where the overpressure of the gases is important. However, in a usual configuration, the opening of the bowl of the cutoff box, and therefore the junction area between the tank and the lid, extends over substantially the entire front face of the tank, otherwise it would be difficult to Insert the different components of the polar cutoff assemblies into the cutoff box, especially when they are assembled beforehand. As a result, the area occupied by this junction zone is large and extends even in the vicinity of the end of the fin blocks. This results in significant forces due to the pressure which cause a mechanical fragility of the cutoff housing, which must be compensated in particular by substantial fastening devices to maintain a good seal between tank and lid.

Le document DE-A-19630471 décrit un appareil selon le préamble la revendication 1.The document DE-A-19630471 describes an apparatus according to claim 1.

Il serait donc avantageux, en particulier dans des appareils interrupteurs de fort calibre ayant à supporter des courants électriques importants, de concevoir un agencement simple du boîtier de coupure permettant de diminuer les contraintes de surpression à l'intérieur des chambres de coupure mais permettant néanmoins de conserver un assemblage facile et rapide du ou des ensembles polaires de coupure ainsi que du système de déclenchement.It would therefore be advantageous, in particular in large-capacity switchgear devices having to withstand large electrical currents, to design a simple arrangement of the cut-off box making it possible to reduce the overpressure stresses inside the breaking chambers but nevertheless making it possible to maintain an easy and fast assembly of the polar cutoff assembly (s) as well as the triggering system.

Un des buts de la présente invention est donc d'offrir une meilleure résistance mécanique et une meilleure étanchéité à la surpression des gaz au niveau de cette zone de jonction du boîtier de coupure en diminuant la surface occupée par la zone de jonction et en rigidifiant les différentes pièces formant le boîtier de coupure.One of the aims of the present invention is thus to offer a better mechanical strength and a better seal against the overpressure of the gases at this junction zone of the cutoff box by reducing the area occupied by the junction zone and by stiffening the different parts forming the breaking box.

Pour cela, l'invention décrit un appareil électrique interrupteur selon la revendication 1.For this purpose, the invention describes an electrical switch device according to claim 1.

Selon la revendication 1, chaque élément du boîtier de coupure de l'appareil interrupteur multipolaire comporte en outre une cloison de séparation entre chaque pôle adjacent, fixée aux parois arrière et avant et au fond dudit élément. Selon une autre caractéristique, chaque élément du boîtier de coupure est préférentiellement constitué d'une seule pièce moulée.According to claim 1, each element of the switch case of the multipole switch device further comprises a partition wall between each adjacent pole, fixed to the rear walls and front and bottom of said element. According to another characteristic, each element of the clipping box is preferably made of a single molded part.

Ainsi, la zone de jonction entre le premier et le second élément du boîtier de coupure se situe dans un plan qui est approximativement parallèle aux première et seconde faces horizontales du boîtier de coupure, alors que dans les solutions connues, cette zone de jonction de situe dans un plan sensiblement vertical, perpendiculaire à l'axe de déplacement horizontal du pont de contacts. Comme la hauteur du boîtier de coupure d'un tel appareil interrupteur est supérieure à sa profondeur en raison de l'agencement des ensembles de coupure, il s'ensuit que la zone de jonction occupe avantageusement une surface nettement plus petite offrant une meilleure résistance mécanique.Thus, the junction zone between the first and the second element of the junction box lies in a plane that is approximately parallel to the first and second horizontal faces of the junction box, whereas in the known solutions, this junction zone is in a substantially vertical plane perpendicular to the axis of horizontal displacement of the contact bridge. Since the height of the breaking box of such a switch apparatus is greater than its depth due to the arrangement of the breaking assemblies, it follows that the junction zone advantageously occupies a much smaller surface area with better mechanical strength. .

Un autre but de l'invention est de proposer une méthode d'assemblage simple et rapide d'un tel appareil électrique interrupteur.Another object of the invention is to provide a simple and fast method of assembling such an electrical switch device.

Pour cela, la méthode d'assemblage comprend successivement une étape d'insertion des ensemble polaires de coupure à l'intérieur du premier élément du boîtier de coupure, une étape d'accrochage d'un système de déclenchement contre le premier élément, puis une étape de fixation du second élément du boîtier de coupure au premier élément de façon à simultanément fermer le boîtier de coupure et permettre le verrouillage du système de déclenchement.For this, the assembly method comprises successively a step of inserting the polar cutoff assemblies inside the first element of the cutoff box, a step of hooking a trigger system against the first element, then a a step of fixing the second element of the breaking box to the first element so as simultaneously to close the breaking box and to allow the locking of the triggering system.

Selon une caractéristique, l'étape d'accrochage du système de déclenchement comprend une étape d'accrochage d'un bloc serrure mécanique au premier élément puis une étape d'accrochage d'un bloc magnéto/thermique au bloc serrure mécanique.According to one characteristic, the latching step of the triggering system comprises a step of attaching a mechanical lock block to the first element and then a step of attaching a magneto / thermal block to the mechanical lock block.

Généralement, ces lignes de courant amont 75, respectivement aval 59, sont raccordées à un circuit d'alimentation électrique amont, respectivement à un circuit de charge aval, par l'intermédiaire de borniers amont, respectivement aval, de l'appareil interrupteur 10 qui en sont pas représentés dans les figures.With reference to the various figures, an electrical switch device 10, for example of the type circuit breaker, contactor or contactor-circuit breaker monopolar or multipole, is responsible for performing the control and / or protection of a downstream electrical circuit, by switching lines The upstream current poles 75 to downstream polar lines 59. Generally, these upstream current lines 75, respectively downstream 59, are connected to an upstream power supply circuit, respectively to a downstream load circuit, via terminal upstream respectively downstream of the switch device 10 which are not shown in the figures.

Chaque pôle de puissance de l'appareil interrupteur possède un ensemble polaire de coupure 80, tel que celui schématisé en figure 4, qui comporte un pont conducteur mobile 83 supportant deux contacts mobiles 84,85 positionnés de part et d'autre d'un axe horizontal médian X. Le pont 83 est mobile en translation selon l'axe de déplacement X dans une direction avant / arrière, de manière à pouvoir séparer ou coller les contacts mobiles 84,85 du pont 83 avec des contacts fixes 76,56 amont et aval de l'appareil interrupteur. L'appareil est dit en position fermée lorsque les contacts mobiles sont collés contre les contacts fixes, permettant de relier les lignes de courant amont 75 et aval 59, et en position ouverte ou déclenchée lorsque les contacts sont séparés.Each power pole of the switch device has a polar cutoff assembly 80, such as that schematized in FIG. figure 4 , which comprises a movable conductive bridge 83 supporting two movable contacts 84, 85 positioned on either side of a median horizontal axis X. The bridge 83 is movable in translation along the axis of X displacement in a forward / backward direction, so as to separate or stick the movable contacts 84,85 of the bridge 83 with fixed contacts 76,56 upstream and downstream of the switch device. The apparatus is said in the closed position when the movable contacts are glued against the fixed contacts, making it possible to connect the upstream current 75 and downstream lines 59, and in the open or triggered position when the contacts are separated.

Dans l'exemple représenté, l'ensemble polaire de coupure 80 comporte également un poussoir 78 capable d'actionner le pont mobile 83 dans le sens ouverture et un ressort de pression de contact, non schématisé, chargé d'actionner le pont mobile 83 dans le sens fermeture. D'autres dispositifs de déplacement du pont mobile 83 sont évidemment envisageables.In the example shown, the polar cutoff assembly 80 also comprises a pusher 78 capable of actuating the movable bridge 83 in the opening direction and a non-schematized contact pressure spring responsible for actuating the movable bridge 83 in the closing direction. Other devices for moving the movable bridge 83 are obviously conceivable.

De part et d'autre de l'axe X du pont mobile 83, l'ensemble polaire de coupure 80 comprend un premier 81 et un second 82 bloc ailettes d'extinction d'arc dont le but est de canaliser vers l'extérieur et de faciliter l'extinction des arcs électriques survenant lors de l'ouverture entre les contacts mobiles 84, respectivement 85, et les contacts fixes correspondants 76, respectivement 56. Divers organes connus, tel qu'un déflecteur 89, peuvent également servir à faciliter la dissipation des arcs électriques. Un déclenchement survenant à la suite à l'apparition d'un fort courant, tel qu'un courant de court-circuit, provoque lors de l'ouverture des contacts une surpression importante des gaz, ces gaz étant alors guidés vers les extrémités externes 81',82' des blocs ailettes 81,82.On either side of the X axis of the movable bridge 83, the polar cutoff assembly 80 comprises a first 81 and a second 82 arc extinguishing blades block whose purpose is to channel outward and to facilitate the extinction of electric arcs occurring during the opening between the movable contacts 84, 85 respectively, and the corresponding fixed contacts 76, 56 respectively. Various known members, such as a deflector 89, can also serve to facilitate the dissipation of electric arcs. A trip occurring as a result of the appearance of a strong current, such as a short-circuit current, causes the opening of the contacts a significant overpressure of the gases, these gases then being guided to the outer ends 81 ', 82' of the fin blocks 81,82.

De préférence, chaque ensemble polaire de coupure 80 est préalablement assemblé pour des raisons de commodité de montage des différentes pièces qui le constituent avant d'être installé dans un boîtier de coupure de l'appareil interrupteur 10. Il faut donc que ce boîtier de coupure d'une part comporte une ouverture suffisante pour permettre l'introduction aisée du ou des ensembles de coupure 80 et d'autre part soit capable d'assurer une bonne résistance aux surpressions des gaz, une fois l'appareil interrupteur assemblé.Preferably, each polar cutoff assembly 80 is previously assembled for reasons of convenience of mounting the various parts that constitute it before being installed in a switchgear housing of the switchgear 10. It is therefore necessary that this breakout box on the one hand has an opening sufficient to allow easy introduction of the cutoff assembly or 80 and on the other hand is able to ensure good resistance to overpressure of the gas, once the switch device assembled.

C'est pourquoi, selon l'invention, le boîtier de coupure de l'appareil interrupteur 10 comprend deux éléments distincts 20,30. Comme indiqué dans les figures 2 et 7, le premier élément 20 du boîtier de coupure possède deux parois latérales 24,25 sensiblement parallèles, comprises entre une paroi arrière 23 et une paroi avant 22, ainsi qu'un fond 21 reliant les parois verticales 22,23,24,25. Le premier élément 20 forme ainsi une première cuve approximativement parallélépipédique, ouverte sur le côté qui est opposé au fond 21. La cavité 29 de la première cuve est susceptible d'accueillir totalement ou partiellement le premier bloc ailettes 81 du ou des ensembles polaires de coupure 80. Le fond 21 du premier élément 20 forme une première face horizontale du boîtier de l'appareil interrupteur 10, par exemple une face supérieure.This is why, according to the invention, the switching unit of the switch device 10 comprises two distinct elements 20,30. As indicated in figures 2 and 7 , the first element 20 of the clipping housing has two substantially parallel side walls 24, 25, between a rear wall 23 and a front wall 22, and a bottom 21 connecting the vertical walls 22, 23, 24, 25. The first element 20 thus forms a first approximately parallelepipedal vessel, open on the the side which is opposite the bottom 21. The cavity 29 of the first tank is able to fully or partially accommodate the first fin block 81 or cut polar assemblies 80. The bottom 21 of the first element 20 forms a first horizontal face of the housing of the switch device 10, for example an upper face.

En référence aux figures 5 et 7, le second élément 30 du boîtier de coupure possède deux parois latérales 34,35 sensiblement parallèles, comprises entre une paroi arrière 33 et une paroi avant 32, ainsi qu'un fond 31 reliant les parois verticales 32,33,34,35. Le second élément 30 forme ainsi une deuxième cuve approximativement parallélépipédique, ouverte sur le côté qui est opposé au fond 31. La cavité 39 de la deuxième cuve est susceptible d'accueillir totalement ou partiellement le second bloc ailettes 82 du ou des ensembles polaires de coupure 80. Le fond 31 du second élément 30 forme une seconde face horizontale du boîtier de l'appareil interrupteur 10, par exemple une face inférieure, opposée à la face supérieure 21.With reference to Figures 5 and 7 , the second element 30 of the cutoff housing has two substantially parallel side walls 34, 35, between a rear wall 33 and a front wall 32, and a bottom 31 connecting the vertical walls 32, 33, 34, 35. The second element 30 thus forms a second approximately parallelepipedic tank, open on the side which is opposite the bottom 31. The cavity 39 of the second tank is able to fully or partially accommodate the second fin block 82 or polar cleavage assemblies 80. The bottom 31 of the second element 30 forms a second horizontal face of the housing of the switch device 10, for example a lower face, opposite to the upper face 21.

Les deux éléments 20 et 30 sont donc conçus comme deux demi-boîtiers rigides de sorte que, lors de l'assemblage de l'appareil 10, ils s'emboîtent entre eux de façon à former un boîtier de coupure fermé créant des chambres de coupure dans les cavités 29,39. En raison de la forme en cuve ouverte d'un côté, il est très facile d'introduire le ou les ensembles polaires de coupure 80 dans chaque demi-boîtier 20,30 du boîtier de coupure. Une fois assemblés, les deux éléments 20,30 sont maintenus entre eux par des moyens de fixation, tels que des moyens d'encliquetage 28,38, composés par exemple d'un organe élastique 28 de l'élément 20 dont l'extrémité peut s'encliqueter dans une ouverture 38 prévue de l'élément 30. D'autres moyens de fixation, tels que des vis de fixation sont aussi envisageables pour maintenir les deux éléments 20,30 entre eux.The two elements 20 and 30 are therefore designed as two rigid half-housings so that, during the assembly of the device 10, they fit together to form a closed cut-off box creating cut-off chambers in cavities 29,39. Due to the open tank shape on one side, it is very easy to introduce the polar cut-off unit (s) 80 into each half-housing 20, 30 of the cut-off housing. Once assembled, the two elements 20,30 are held together by fixing means, such as latching means 28,38, composed for example of an elastic member 28 of the element 20 whose end can snap into an opening 38 provided of the element 30. Other fastening means, such as fixing screws are also conceivable to maintain the two elements 20,30 between them.

Dans le cas d'un appareil interrupteur multipolaire, comme dans la figure 7, chaque élément 20,30 comporte de plus une cloison de séparation 26,36 entre chaque pôle adjacent, de façon à isoler les pôles entre eux. Chacune des cloisons 26, respectivement 36, est fixée aux parois arrière 23, respectivement 33, et avant 22, respectivement 32, ainsi qu'au fond 21, respectivement 31, de l'élément 20, respectivement 30. Ces cloisons 26, respectivement 36, sont sensiblement parallèles aux parois latérales 24,25, respectivement 34,35 et forment un caissonnage permettant de définir des cavités 29 séparées, respectivement 39, créant ainsi des chambres de coupure distinctes pour chaque pôle.In the case of a multipole switch device, as in the figure 7 each element 20,30 further comprises a partition wall 26,36 between each adjacent pole, so as to isolate the poles between them. Each of the partitions 26, respectively 36, is fixed to the rear walls 23, respectively 33, and before 22, respectively 32, and the bottom 21, respectively 31, of the element 20, respectively 30. These partitions 26, respectively 36 , are substantially parallel to the side walls 24,25, respectively 34,35 and form a box for defining separate cavities 29, respectively 39, thus creating separate breaking chambers for each pole.

La figure 7 montre un appareil interrupteur tripolaire, dont chaque élément 20,30 comporte donc deux cloisons de séparation 26,36. Dans le mode de réalisation présenté, chaque cloison de séparation 36 comporte de plus un évidement intérieur dans lequel vient s'insérer la cloison de séparation correspondante 26. On crée ainsi un chevauchement entre les cloisons de séparation 26,36. Cette solution présente l'avantage de garantir une bonne étanchéité entre les différentes chambres de coupure 29;39 des pôles, de respecter les lignes de fuite entre pôles et de rigidifier la zone de jonction entre les cloisons 26 et 36.The figure 7 shows a three-pole switch device, each element 20,30 thus comprises two partition walls 26,36. In the embodiment shown, each partition wall 36 further comprises an inner recess in which is inserted the corresponding partition wall 26. This creates an overlap between the partition walls 26,36. This solution has the advantage of guaranteeing a good seal between the different breaking chambers 29, 39 of the poles, of respecting the lines of leakage between poles and of stiffening the junction zone between the partitions 26 and 36.

Un chevauchement est également facilement envisageable pour la jonction entre les parois arrières 23 et 33 et entre les parois latérales 24 et 34, 25 et 35. Par contre, les parois avant 22,32 sont agencées pour laisser un espace suffisant entre elles permettant notamment le coulissement du poussoir 78 de chaque pôle d'avant en arrière.An overlap is also easily conceivable for the junction between the rear walls 23 and 33 and between the side walls 24 and 34, 25 and 35. By cons, the front walls 22, 32 are arranged to allow sufficient space between them allowing in particular the sliding of the pusher 78 of each pole from front to back.

De préférence, chaque élément 20,30 du boîtier de coupure est constitué d'une seule pièce moulée en matériau plastique isolant, ce qui simplifie la fabrication de l'appareil interrupteur et ce qui assure en plus une bonne étanchéité entre les différentes cavités 29,39 de chaque pôle et une meilleure rigidité des éléments 20,30. Par ailleurs, les dimensions intérieures des deux éléments 20,30 sont étudiées pour que, lorsqu'ils sont fixés l'un contre l'autre, ils puissent maintenir en position les ensembles de coupure 80 des différents pôles placés à l'intérieur. De plus, les fonds 21,31 des deux éléments 20,30 comportent plusieurs ouies d'ouvertures 27,37 de façon à permettre l'évacuation vers l'extérieur des gaz des différentes chambres de coupure 29,39, en haut et en bas de l'appareil interrupteur 10.Preferably, each element 20, 30 of the breaking box consists of a single molded part made of insulating plastic material, which simplifies the manufacture of the switch device and which also ensures a good seal between the various cavities 29, 39 of each pole and a better stiffness of the elements 20,30. Furthermore, the internal dimensions of the two elements 20,30 are designed so that, when they are fixed against each other, they can hold in position the clipping assemblies 80 of the different poles placed inside. In addition, the bottoms 21,31 of the two elements 20,30 comprise several openings 27,37 openings so as to allow the evacuation to the outside of the gases of the different chambers of cutoff 29,39, up and down of the switch device 10.

La zone de jonction entre les deux éléments 20,30, correspondant à la jointure entre les deux éléments assemblés, se situe dans un plan approximativement horizontal (voir figures 1 et 6), sensiblement parallèle aux fonds 21,31 du boîtier de coupure. Or dans une solution classique, la zone de jonction ente cuve et couvercle se situe à l'avant du boîtier de coupure dans un plan sensiblement vertical, orthogonal à l'axe de déplacement horizontal X. Par ailleurs, dans un tel appareil interrupteur, la hauteur du boîtier de coupure est inférieure à sa profondeur, étant donné la structure et l'agencement des ensembles polaires de coupure 80.The junction zone between the two elements 20,30, corresponding to the joint between the two assembled elements, lies in an approximately horizontal plane (see Figures 1 and 6 ), substantially parallel to the bottoms 21,31 of the breaking box. However, in a conventional solution, the junction zone between the tank and the cover is located at the front of the breakout box in a substantially vertical plane, orthogonal to the horizontal axis of displacement X. Furthermore, in such a switch device, the The height of the cutoff housing is less than its depth, given the structure and arrangement of the cutoff polar assemblies 80.

Ainsi, grâce à l'invention, la surface occupée par la zone de jonction.est donc nettement plus petite que dans une solution classique. En conséquence, pour une pression des gaz donnée, les efforts de pression exercés sur la zone de jonction entre les deux éléments 20,30 sont nettement moindres ce qui permet d'obtenir une meilleure résistance mécanique. Cette disposition permet également de mieux rigidifier les différentes parties des éléments 20,30, notamment au niveau des cloisons de séparation 26,36. De plus, la zone de jonction entre les deux éléments 20,30 peut être avantageusement éloignée des extrémités externes 81',82' des blocs ailettes 81,82, pour éviter d'avoir à supporter une trop forte surpression. Grâce à cet agencement du boîtier de coupure en deux éléments 20,30 distincts, on obtient avantageusement d'une part une introduction facile des ensembles polaires de coupure pré-assemblés, d'autre part une meilleure tenue des chambres de coupure des pôles aux surpressions des gaz.Thus, thanks to the invention, the area occupied by the junction zone is therefore much smaller than in a conventional solution. As a result, for given gas pressure, the pressure forces exerted on the junction zone between the two elements 20,30 are significantly lower which allows to obtain a better mechanical strength. This arrangement also makes it possible to better stiffen the different parts of the elements 20, 30, especially at the level of the partition walls 26, 36. In addition, the junction zone between the two elements 20,30 may advantageously be remote from the outer ends 81 ', 82' of the fin blocks 81, 82, to avoid having to withstand excessive overpressure. Thanks to this arrangement of the breaking unit in two separate elements 20,30, one advantageously obtains on the one hand an easy introduction of pre-assembled polar cutoff assemblies, on the other hand a better holding of the poles breaking chambers overpressures gases.

Une fois assemblées, les parois latérales 24,25 et 34,35 des éléments 20 et 30 forment des faces latérales du boîtier de l'appareil interrupteur 10. Le boîtier de coupure constitue alors un socle de l'appareil interrupteur 10 sur lequel pourra être notamment fixé un système de déclenchement. Par ailleurs, sur l'une ou l'autre des parois arrières 23,33 du boîtier de coupure, on peut disposer des moyens permettant d'accrocher l'appareil interrupteur 10 sur un support quelconque de montage tel qu'un rail DIN ou autre. Dans les figures jointes, ces moyens d'accrochage sont disposés sur la paroi arrière 23 de l'élément 20.Once assembled, the side walls 24,25 and 34,35 of the elements 20 and 30 form side faces of the housing of the switch device 10. The switch box then constitutes a base of the switch device 10 on which it can be in particular fixed a trigger system. Moreover, on one or the other of the rear walls 23, 23 of the cut-off housing, it is possible to have means making it possible to hang the switch device 10 on any mounting support such as a DIN rail or the like . In the accompanying figures, these attachment means are arranged on the rear wall 23 of the element 20.

L'appareil interrupteur 10 comporte un système de déclenchement constitué d'un ou plusieurs blocs fonctions dans le but d'assurer la commande et/ou la protection du circuit électrique aval. Dans l'exemple présenté, le système de déclenchement comporte un bloc de coupure magnéto/thermique 50 électromécanique pour chaque pôle et un bloc serrure mécanique 40. On pourrait envisager de façon équivalente l'utilisation d'autres blocs fonctions tel qu'un bloc de coupure magnétique et/ou thermique à détection électronique.The switch device 10 comprises a trigger system consisting of one or more function blocks for the purpose of providing control and / or protection of the downstream electrical circuit. In the example presented, the triggering system comprises an electromechanical magneto / thermal cut-off block 50 for each pole and a mechanical lock block 40. Equally, the use of other function blocks such as a block of magnetic and / or thermal cutoff with electronic detection.

De façon connue, le bloc serrure mécanique 40 est muni d'une serrure 41 qui agit sur chaque poussoir 78 de pôle, dans le sens ouverture, par exemple par l'intermédiaire d'un palonnier non schématisé pour des raisons de simplification. De même, il est connu qu'un bloc de coupure magnéto/thermique 50 électromécanique est parcouru par le courant de puissance circulant dans le pôle correspondant et peut comporter en série un déclencheur thermique 51, tel qu'un bilame actionné par une chaufferette, et un déclencheur magnétique 52, composé d'une bobine magnétique et d'un percuteur, lequel agit sur le pont mobile 83 du pôle dans le sens ouverture par exemple par l'intermédiaire d'une tige de percussion traversant le poussoir 78, non schématisée pour des raisons de simplification.In known manner, the mechanical lock block 40 is provided with a lock 41 which acts on each push rod 78, in the opening direction, for example by means of a non-schematized lifter for reasons of simplification. Likewise, it is known that an electromechanical magneto / thermal cutoff unit 50 is traversed by the power current flowing in the corresponding pole and may comprise in series a thermal trip device 51, such as a bimetallic strip actuated by a heater, and a magnetic trigger 52, composed of a magnetic coil and a striker, which acts on the movable bridge 83 of the pole in the opening direction, for example via a percussion rod passing through the pusher 78, not schematized for reasons of simplification.

Pour chaque pôle, l'appareil interrupteur 10 comporte, de façon courante, un conducteur fixe amont 75 formant la ligne polaire de courant amont et dont une extrémité possède sensiblement une forme de U matérialisé par deux branches 73 et 74 (voir figure 4). Une branche 74 du U porte le contact fixe amont 76 qui coopère avec le contact mobile 84. Selon l'invention, le conducteur amont 75 est introduit dans l'appareil interrupteur 10 en insérant la paroi avant 22 du premier élément 20 du boîtier de coupure dans l'espace intérieur situé entre les deux branches 73,74 du U. L'écartement des branches 73,74 peut être conçu pour que, une fois inséré, le conducteur amont 75 soit maintenu par coincement des branches 73,74 autour de la paroi avant 22.For each pole, the switch apparatus 10 comprises, in a current manner, an upstream fixed conductor 75 forming the polar line of upstream current and one end of which has substantially a U-shaped materialized by two branches 73 and 74 (see FIG. figure 4 ). A branch 74 of the U carries the upstream fixed contact 76 which cooperates with the movable contact 84. According to the invention, the upstream conductor 75 is introduced into the switch apparatus 10 by inserting the front wall 22 of the first element 20 of the breaking housing in the interior space between the two branches 73,74 of the U. The spacing of the branches 73,74 may be designed so that, once inserted, the upstream conductor 75 is maintained by jamming the branches 73,74 around the front wall 22.

De même, l'appareil interrupteur 10 comporte également pour chaque pôle un conducteur fixe aval 55 dont une extrémité possède sensiblement une forme de U matérialisé par deux branches 53 et 54 (voir figure 3). Une branche 54 du U porte le contact fixe aval 56 qui coopère avec le contact mobile 85. Dans l'exemple de la figure 3, le conducteur aval 55 est connecté en série au déclencheur thermique 51, au déclencheur magnétique 52 puis à la ligne polaire de courant aval 59. Le conducteur aval 55 est donc fixé au bloc de coupure magnéto/thermique 50 du pôle. Lorsque le ou les blocs 50 sont assemblés dans l'appareil interrupteur 10 (voir figure 5), la paroi avant 32 du second élément 30 du boîtier de coupure est introduite dans l'espace intérieur situé entre les deux branches 53,54 du U de chaque conducteur aval 55, permettant ainsi d'assurer le maintien et le verrouillage du système de déclenchement en même temps que la fermeture du boîtier de coupure. L'écartement des branches 53,54 peut être conçu pour que le conducteur aval 55 soit maintenu par coincement des branches 53,54 autour de la paroi avant 32.Similarly, the switch device 10 also comprises for each pole a downstream fixed conductor 55 whose end has substantially a U-shaped materialized by two branches 53 and 54 (see figure 3 ). A branch 54 of the U carries the downstream fixed contact 56 which cooperates with the movable contact 85. In the example of FIG. figure 3 the downstream conductor 55 is connected in series with the thermal trip unit 51, with the magnetic trip unit 52 and then with the downstream pole line 59. The downstream conductor 55 is thus fixed to the magneto / thermal cut-off block 50 of the pole. When the block or blocks 50 are assembled in the switch device 10 (see figure 5 ), the front wall 32 of the second element 30 of the breaking box is introduced into the interior space between the two branches 53,54 of the U of each downstream conductor 55, thus ensuring the maintenance and locking of the system of triggering at the same time as the closing of the breaking box. The spacing of the branches 53,54 may be designed so that the downstream conductor 55 is held by wedging the branches 53,54 around the front wall 32.

L'invention se rapporte également à une méthode simple et rapide d'assemblage d'un appareil électrique interrupteur tel que décrit précédemment. Selon l'invention, la méthode comprend successivement :

  • Une première étape d'insertion A de chaque ensemble polaire de coupure 80, préalablement monté, dans une chambre de coupure créée par chaque cavité 29 du premier élément 20 du boîtier de coupure. La forme de cuve ouverte du premier élément 20 permet une insertion très facile par l'ouverture de la cuve. Cette étape est schématisée par la flèche A de bas en haut entre la figure 2, représentant le premier élément 20, et la figure 4, représentant un ensemble de coupure 80. Le ou les conducteurs polaires amont 75 sont eux soit insérés dans une étape préliminaire d'insertion, soit insérés durant l'étape A, en particulier s'ils sont préalablement assemblés avec le ou les ensembles polaires de coupure 80. Les branches 74, 73 du U sont positionnées de part et d'autre de la paroi avant 22 du premier élément 20 de manière à maintenir, par exemple par coincement, en position fixe le conducteur amont 75.
  • Une deuxième étape d'accrochage B du système de déclenchement 40,50 de l'appareil interrupteur 10 contre le premier élément 20. Cette étape est schématisée par la flèche B entre la figure 2 et la figure 3, représentant un système de déclenchement 40,50. Suivant le nombre de blocs fonctions constituant le système de déclenchement, l'étape B peut être décomposée en plusieurs phases. Dans un appareil 10 dont le système de déclenchement inclut un bloc serrure mécanique 40 et un ou plusieurs blocs de coupure magnéto/thermique 50, l'étape B comprend une première étape d'accrochage du bloc serrure 40 contre la paroi avant 22 du premier élément 20. Le bloc serrure 40 est par exemple introduit dans un mouvement vertical de haut en bas et est maintenu au premier élément 20 par un dispositif de glissière, de queue d'aronde ou autres, verrouillant tout mouvement horizontal du bloc 40. L'étape B comprend ensuite une deuxième étape d'accrochage permettant de solidariser chaque bloc magnéto/thermique 50 à l'ensemble constitué du premier élément 20 et du bloc 40. Le bloc magnéto/thermique 50 est par exemple introduit dans un mouvement horizontal, et est maintenu au bloc serrure 40 par un dispositif de glissière, de queue d'aronde ou autres, jusqu'en butée contre le premier élément 20. Une fois que chaque bloc magnéto/thermique 50 est solidarisé au bloc serrure 40, le système de déclenchement complet peut être ainsi bloqué contre tout mouvement vertical. On obtient alors l'ensemble schématisé dans le haut de la figure 5. Durant cette étape, on met en place également les organes agissant sur les poussoirs 78.
  • Une troisième étape de fixation C du second élément 30 au premier élément 20 de façon à fermer le boîtier de coupure et à permettre en plus le verrouillage final du système de déclenchement contre le boîtier de coupure. La forme de cuve ouverte du second élément 30 permet d'introduire facilement le second bloc ailettes 82 de chaque ensemble polaire de coupure 80, préalablement introduit dans le premier élément 20, dans une chambre de coupure créée par chaque cavité 39. Cette étape est schématisée par la flèche C de bas en haut de la figure 5. Durant cette étape C, la paroi avant 32 du second élément 30 est insérée et maintenue, par exemple par coincement, entre les deux branches 53 et 54 du U de chaque conducteur aval 55 fixé à chaque bloc magnéto/thermique 50, ce qui permet de verrouiller complètement le système de déclenchement.
The invention also relates to a simple and quick method of assembling an electrical switch device as described above. According to the invention, the method comprises successively:
  • A first insertion step A of each polar cutoff assembly 80, previously mounted, in an interrupting chamber created by each cavity 29 of the first element 20 of the breaking unit. The open vessel shape of the first element 20 allows very easy insertion through the opening of the vessel. This step is schematized by the arrow A from bottom to top between the figure 2 , representing the first element 20, and the figure 4 , representing a cutoff assembly 80. The upstream polar conductor (s) 75 are either inserted in a preliminary insertion step or inserted during step A, in particular if they are previously assembled with the polar assembly (s) of 80. The branches 74, 73 of the U are positioned on either side of the front wall 22 of the first element 20 so as to hold, for example by wedging, in a fixed position the upstream conductor 75.
  • A second hooking step B of the triggering system 40,50 of the switch device 10 against the first element 20. This step is shown schematically by the arrow B between the figure 2 and the figure 3 , representing a trigger system 40,50. Depending on the number of function blocks constituting the triggering system, step B can be decomposed into several phases. In an apparatus 10 whose trigger system includes a mechanical lock block 40 and one or more magneto / thermal cutoff blocks 50, step B comprises a first step of hooking the lock block 40 against the front wall 22 of the first element 20. The lock block 40 is for example introduced in a vertical movement from top to bottom and is held at the first element 20 by a slide, dovetail or other device, locking any horizontal movement of the block 40. The step B then comprises a second hooking step enabling each magneto / heat block 50 to be secured to the assembly consisting of the first element 20 and the block 40. The magneto / thermal block 50 is for example introduced in a horizontal movement, and is maintained the lock block 40 by a slide device, dovetail or the like, as far as the stop against the first element 20. Once each magneto / thermal block 50 is secured to the blo c lock 40, the complete trigger system can thus be blocked against any vertical movement. We then obtain the whole schematized at the top of the figure 5 . During this step, the organs acting on the pushers 78 are also put in place.
  • A third fixing step C of the second element 30 to the first element 20 so as to close the breaking box and to allow in addition the final locking of the trigger system against the breakout box. The open tank shape of the second element 30 makes it possible to easily introduce the second fin block 82 of each polar cutoff assembly 80, previously introduced into the first element 20, in an interrupting chamber created by each cavity 39. This step is schematized by the arrow C from bottom to top of the figure 5 . During this step C, the front wall 32 of the second element 30 is inserted and held, for example by wedging, between the two branches 53 and 54 of the U of each downstream conductor 55 attached to each magneto / thermal block 50, which makes it possible to completely lock the trigger system.

La fixation du second élément 30 contre le premier élément 20 est réalisée préférentiellement par les moyens d'encliquetage 28,38 ou par d'autres moyens tels que des vis. Cette étape C permet donc avantageusement, en une seule opération, à la fois de verrouiller complètement le système de déclenchement, grâce à la paroi avant 32, et de fermer le boîtier de coupure, en fixant le second élément 30 sur le premier élément 20. On obtient ainsi une méthode simple, rapide et efficace d'assemblage de l'appareil interrupteur.Fixing the second element 30 against the first element 20 is preferably performed by the latching means 28,38 or by other means such as screws. This step C thus advantageously makes it possible, in a single operation, both to completely lock the triggering system, thanks to the front wall 32, and to close the breaking box, by fixing the second element 30 on the first element 20. This provides a simple, fast and efficient method of assembling the switch device.

Une étape supplémentaire de fixation permet ensuite de positionner un bloc face avant 60 comprenant des organes de commande et/ou de visualisation de l'appareil interrupteur 10, à l'avant du système de déclenchement 40,50, pour finalement obtenir l'appareil 10 assemblé tel que représenté dans les figures 1 et 6.An additional fixing step then makes it possible to position a front face block 60 comprising control and / or display members of the switch device 10, at the front of the trigger system 40, 50, to finally obtain the apparatus 10. assembled as shown in Figures 1 and 6 .

En plus des avantages déjà cités, une telle conception apporte une grande modularité: en effet chaque module de l'appareil interrupteur 10 peut être conçu et assemblé séparément l'un avec l'autre (ensemble de coupure polaire, bloc serrure, bloc magnéto/thermique, bloc face avant, etc...), ce qui facilite non seulement le remplacement d'un module par un autre durant les opérations de maintenance mais ce qui facilite également la conception à partir d'une même base d'appareils électriques interrupteurs comportant des fonctions différentes ou la conception d'une large gamme d'appareils interrupteurs utilisant certains modules communs.In addition to the advantages already mentioned, such a design provides a great modularity: indeed each module of the switch device 10 can be designed and assembled separately with each other (polar cut assembly, lock block, magneto block / thermal, front panel block, etc ...), which facilitates not only the replacement of one module by another during maintenance but also facilitates the design from a single base of electrical devices switches with different functions or the design of a wide range of switchgear using certain common modules.
