Description

La présente invention concerne un dispositif de coupure comprenant un boítier de chambre de coupure d'arc électrique muni d'ailettes d'extinction d'arc, ce dispositif étant destiné à être utilisé dans chaque pôle d'appareils interrupteurs, notamment des disjoncteurs ou des contacteur-disjoncteurs basse tension multipolaires.The present invention relates to a switching device comprising a arc breaking chamber box provided with arc extinguishing fins, this device being intended to be used in each pole of switchgear, in particular low-voltage circuit breakers or contactor-circuit breakers multipolar.

Il existe différentes solutions pour la mise en place des ailettes d'extinction d'arc dans un boítier de chambre de coupure de tels appareils interrupteurs. Le brevet DE19757332 décrit par exemple un dispositif dans lequel la cage du pont de contacts mobiles, située à l'intérieur du boítier de la chambre de coupure, présente une forme de peigne dont les rainures sont aptes à loger les extrémités des ailettes d'extinction d'arc, assurant ainsi leur maintien. Dans le brevet EP0556109, les ailettes d'extinction d'arc sont isolées des contacts mobiles grâce également à des parois latérales situées de chaque côté de la cage du pont de contacts mobiles.There are different solutions for the installation of fire extinguisher fins of arc in a case of breaking chamber of such switching devices. The patent DE19757332 describes for example a device in which the cage of the contact bridge mobile, located inside the box of the breaking chamber, has a shape comb whose grooves are able to accommodate the ends of the extinguishing fins arc, thus ensuring their maintenance. In patent EP0556109, the extinguishing fins are isolated from the movable contacts thanks also to the side walls located on each side of the cage of the mobile contact bridge.

Cependant, il est également nécessaire d'assurer une bonne rigidité mécanique des parois latérales du boítier de la chambre de coupure notamment à cause du souffle survenant lors d'un déclenchement du disjoncteur ou du contacteur-disjoncteur, provoqué en cas de court-circuit par exemple. Pour cela, il peut être nécessaire de renforcer la structure de ces parois latérales du boítier.However, it is also necessary to ensure good rigidity mechanics of the side walls of the enclosure of the breaking chamber, in particular at cause of the blast occurring during tripping of the circuit breaker or of the contactor-circuit breaker, caused in the event of a short circuit, for example. For this, it can be necessary to strengthen the structure of these side walls of the housing.

L'invention a donc pour but de proposer un dispositif unique permettant à la fois de guider les ailettes d'extinction d'arc dans le boítier de la chambre de coupure, de les isoler des contacts mobiles et de rigidifier en même temps les parois latérales du boítier de la chambre de coupure.The invention therefore aims to provide a unique device allowing the time to guide the arc extinguishing fins in the casing of the breaking chamber, to isolate them from the moving contacts and at the same time stiffen the side walls the enclosure of the breaking chamber.

Selon l'invention, le dispositif de coupure d'appareil interrupteur multipolaire est constitué, pour chaque pôle, d'un boítier de coupure comprenant deux parois latérales entre lesquelles est disposée une cage supportant un pont de contacts mobiles associés à des contacts fixes, et comprenant deux ensembles de plusieurs ailettes d'extinction d'arc en forme de U. Ce dispositif est caractérisé par le fait que les parois latérales du boítier de coupure comportent des moyens de guidage pour les extrémités des ailettes d'extinction d'arc, ces moyens de guidage étant de plus aptes à assurer une isolation électrique entre les contacts mobiles et les extrémités des ailettes d'extinction d'arc. Selon une caractéristique de l'invention, ces moyens de guidage sont moulés avec chaque paroi latérale vers l'intérieur du boítier de coupure et sont constitués d'un corps prolongé d'une nervure latérale formant, avec la paroi latérale, un logement pour recevoir les extrémités des d'ailettes d'extinction d'arc. De plus, le corps des moyens de guidage contribue également à renforcer la rigidité mécanique des parois latérales du boítier de coupure.According to the invention, the switch-off device multipolar consists of, for each pole, a breaking box comprising two side walls between which is disposed a cage supporting a contact bridge mobiles associated with fixed contacts, and comprising two sets of several U-shaped arc extinguishing fins. This device is characterized in that the side walls of the switch box include guide means for the ends of the arc extinguishing fins, these guide means being moreover capable of provide electrical insulation between the movable contacts and the ends of the arc extinguishing fins. According to a characteristic of the invention, these means of guides are molded with each side wall towards the inside of the switch box and consist of a body extended by a lateral rib forming, with the wall lateral, a housing for receiving the ends of the arc extinguishing fins. Of more, the body of the guide means also contributes to strengthening the rigidity mechanical side walls of the switch box.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation donné à titre d'exemple et représenté par les dessins annexés sur lesquels :

  • - la figure 1 montre une vue partielle des chambres de coupure d'un appareil interrupteur tripolaire dans laquelle ne figurent que les ensembles d'ailettes d'extinction d'arc,
  • la figure 2 représente une vue en coupe longitudinale d'une chambre de coupure selon l'invention.
    • The invention will now be described in more detail with reference to an embodiment given by way of example and represented by the appended drawings in which:
  • FIG. 1 shows a partial view of the breaking chambers of a three-pole switching device in which only the arcing-extinguishing fin assemblies appear,
  • FIG. 2 represents a view in longitudinal section of a breaking chamber according to the invention.

    • Le dispositif de coupure décrit dans l'invention est situé dans une chambre de coupure 19 formée par un boítier de coupure isolant 20 pour chaque pôle d'un appareil interrupteur, par exemple de type contacteur-disjoncteur. Ce boítier de coupure 20 a une forme sensiblement parallélépipédique et comporte deux parois latérales 24 et une paroi de fond 25. Dans un appareil interrupteur multipolaire, les boítiers de coupure 20 des différents pôles sont adjacents les uns aux autres et les parois latérales 24 adjacentes sont communes, comme représenté sur la figure 1.The switching device described in the invention is located in a room break 19 formed by an insulating break box 20 for each pole of a switch device, for example of the contactor-circuit breaker type. This case of cut 20 has a substantially parallelepiped shape and has two walls side 24 and a bottom wall 25. In a multi-pole switching device, the break boxes 20 of the different poles are adjacent to each other and the adjacent side walls 24 are common, as shown in FIG. 1.

    La figure 2 montre une chambre de coupure dans laquelle se trouve un pont de contacts mobiles 11, monté à l'intérieur d'une cage 10 et muni d'un poussoir isolant 14 et de deux contacts mobiles 12. Chaque contact mobile 12 de ce pont 11 coopère avec un contact fixe non représenté sur les figures jointes. Le poussoir 14 et le pont de contacts 11 sont guidés en translation dans la cage 10 selon un axe repéré X. Lors d'un déclenchement de l'appareil interrupteur, le mécanisme de déclenchement agit sur le poussoir 14 pour séparer les contacts mobiles 12 des contacts fixes. Un ressort de compression 18 prenant appui d'une part sur le fond 25 du boítier de coupure grâce à une forme adaptée 13 de la cage 10 et d'autre part sous le pont de contacts 11, tend à appuyer les contacts fixes 12 contre les contacts fixes.Figure 2 shows a switching chamber in which there is a movable contact bridge 11, mounted inside a cage 10 and provided with a pusher insulator 14 and two movable contacts 12. Each movable contact 12 of this bridge 11 cooperates with a fixed contact not shown in the attached figures. Pusher 14 and the contact bridge 11 are guided in translation in the cage 10 along an identified axis X. When the switching device trips, the trigger acts on pusher 14 to separate movable contacts 12 from fixed contacts. A compression spring 18 bearing on the one hand on the bottom 25 of the breaking box thanks to a suitable shape 13 of the cage 10 and on the other hand under the contact bridge 11 tends to press the fixed contacts 12 against the fixed contacts.

    Pour dissiper l'arc électrique pouvant survenir lors d'un déclenchement de l'appareil, deux ensembles d'ailettes 17 sont disposés dans le boítier de coupure de part et d'autre de la cage 10, de façon à pouvoir agir sur les arcs électriques émanant des deux contacts mobiles 12. Chaque ensemble d'ailettes 17 est constitué d'une pluralité d'ailettes d'extinction d'arc 16 métalliques, parallèles les unes aux autres, en forme de U, chacune dotée d'une base 16b et de deux extrémités 16a dirigées vers la cage 10 ; chaque ensemble d'ailettes 17 comporte aussi une pièce d'assemblage 15 isolante, perpendiculaire aux ailettes 16, entourant la base 16b des ailettes 16 et destinée à fixer et à maintenir celles-ci entre elles à une distance fixe.To dissipate the electric arc that can occur during a trip of the device, two sets of fins 17 are arranged in the cut-off box of on either side of the cage 10, so as to be able to act on the electric arcs emanating two movable contacts 12. Each set of fins 17 consists of a plurality of metal arc extinguishing fins 16, parallel to each other, in U-shaped, each with a base 16b and two ends 16a facing the cage 10; each set of fins 17 also includes an assembly part 15 insulating, perpendicular to the fins 16, surrounding the base 16b of the fins 16 and intended to fix and maintain them between them at a fixed distance.

    Les extrémités 16a des ailettes sont disposées à proximité de chaque contact mobile 12, suivant une direction parallèle à l'axe X correspondant au mouvement effectué par le pont de contacts mobiles 11 lors d'un déclenchement, de façon à agir le plus efficacement possible contre un arc électrique survenant entre un contact fixe et un contact mobile.The ends 16a of the fins are arranged close to each movable contact 12, in a direction parallel to the X axis corresponding to the movement made by the movable contact bridge 11 during a tripping, in order to act as effectively as possible against an electric arc occurring between a fixed contact and a mobile contact.

    Néanmoins les extrémités 16a des ailettes 16 doivent être protégées par une cloison isolante du contact mobile 12, du contact fixe et du pont 11. De plus, il est judicieux de prévoir des moyens de guidage pour les ensembles d'ailettes 17, de manière à pouvoir les insérer facilement et à les maintenir dans le boítier de coupure 20. Enfin, étant donné la puissance que peut représenter le souffle lié à l'arc électrique au moment d'un déclenchement sur court-circuit par exemple, le boítier de coupure 20 peut être soumis à des pressions importantes et il peut s'avérer nécessaire de rigidifier les parois latérales 24 du boítier de coupure 20, à proximité du pont de contacts mobiles 11.However, the ends 16a of the fins 16 must be protected by an insulating partition of the movable contact 12, of the fixed contact and of the bridge 11. In addition, it is judicious to provide guide means for the sets of fins 17, so that you can insert them easily and keep them in the switch box 20. Finally, given the power that the breath linked to the electric arc can represent at the time of a tripping on short circuit for example, the breaking box 20 may be subjected to significant pressures and it may be necessary to stiffen the side walls 24 of the breaking box 20, near the contact bridge mobile 11.

    Pour répondre à ces trois exigences, l'invention prévoit un dispositif dans lequel les parois latérales 24 du boítier de coupure 20 comportent des moyens de guidage pour les extrémités 16a des ailettes d'extinction d'arc 16. Selon un mode de réalisation préférée, ces moyens de guidage comportent un corps 21, moulé avec chaque paroi latérale 24 vers l'intérieur du boítier de coupure 20 et prolongé par une nervure latérale 22 sensiblement parallèle à la paroi latérale 24, formant avec cette paroi un logement 23 apte à recevoir les extrémités 16a des ailettes d'extinction d'arc 16. Le corps 21 peut, à titre d'exemple, présenter une section sensiblement rectangulaire sur toute la hauteur de la paroi 24. La longueur de la nervure latérale 22 permet de recouvrir suffisamment les extrémités 16a pour les isoler électriquement des contacts mobiles 12, des contacts fixes et du pont de contacts mobiles 11, lors de l'apparition d'un arc électrique.To meet these three requirements, the invention provides a device in which the side walls 24 of the breaking box 20 comprise means for guide for the ends 16a of the arc extinguishing fins 16. According to a mode of preferred embodiment, these guide means comprise a body 21, molded with each side wall 24 towards the inside of the breaking box 20 and extended by a lateral rib 22 substantially parallel to the lateral wall 24, forming with this wall a housing 23 adapted to receive the ends 16a of the arc extinguishing fins 16. The body 21 may, for example, have a section which is substantially rectangular over the entire height of the wall 24. The length of the lateral rib 22 allows the ends 16a to be covered sufficiently to insulate them electrically movable contacts 12, fixed contacts and movable contact bridge 11, when the appearance of an electric arc.

    Des ergots 26, moulé avec chaque paroi latérale 24 vers l'intérieur du boítier de coupure 20, sont destinés à guider et à maintenir latéralement chaque ensemble d'ailettes 17 en prenant appui sur la face arrière 15a de la pièce d'assemblage 15 des ailettes 16. Ainsi, grâce d'une part à ces ergots 26 et d'autre part aux moyens de guidage des extrémités 16a des ailettes d'extinction d'arc 16, chaque ensemble d'ailettes peut être inséré rapidement et maintenu dans un boítier de coupure 20, facilitant ainsi la fabrication des chambres de coupure 19.Lugs 26, molded with each side wall 24 towards the inside of the cutout box 20, are intended to guide and laterally maintain each set of fins 17 by resting on the rear face 15a of the part assembly 15 of the fins 16. Thus, thanks on the one hand to these lugs 26 and on the other hand to the means for guiding the ends 16a of the arc extinguishing fins 16, each set of fins can be quickly inserted and held in a housing cut-off 20, thus facilitating the manufacture of the cut-off chambers 19.

    Le corps 21 permet en outre de renforcer notablement, sans rajouter d'élément supplémentaire, la rigidité des parois latérales 24 à proximité de la zone où peut se déclencher un arc électrique entre contacts mobiles et contacts fixes, c'est-à-dire là où la pression exercée sur ces parois latérales est la plus forte. On peut ainsi réduire l'épaisseur générale des parois latérales 24 sachant qu'elles sont renforcées dans leurs zones les plus critiques ; il s'en suit une optimisation générale des dimensions pour un appareil interrupteur multipolaire.The body 21 also makes it possible to reinforce notably, without adding additional element, the rigidity of the side walls 24 near the area where can trigger an electric arc between moving contacts and fixed contacts, i.e. where the pressure on these side walls is greatest. We can thus reduce the general thickness of the side walls 24 knowing that they are reinforced in their most critical areas; it follows a general optimization of dimensions for a multi-pole switch device.

    Par ailleurs, les moyens de guidage des extrémités 16a des ailettes d'extinction d'arc 16 servent également à faciliter l'insertion et à assurer le maintien latéral de la cage 10 du pont de contacts mobiles 11 dans le boítier de coupure 20. Le corps 21 des moyens de guidage comporte en effet une face 21a dans un plan perpendiculaire à la paroi latérale 24, à l'opposé de la nervure 22. Les faces 21a de deux corps 21 situés le long d'une même paroi latérale 24 d'un boítier de coupure 20 forment avec cette paroi latérale 24 un logement 27 dans lequel la cage 10 peut coulisser suivant l'axe X au moment de son insertion et qui ensuite assure le maintien latéral de cette cage 10 et donc du pont de contacts mobiles 11.Furthermore, the means for guiding the ends 16a of the fins arc extinguisher 16 also serve to facilitate insertion and ensure maintenance side of the cage 10 of the movable contact bridge 11 in the cutout box 20. The body 21 of the guide means indeed has a face 21a in a plane perpendicular to the side wall 24, opposite the rib 22. The faces 21a of two bodies 21 located along the same side wall 24 of a cut-off box 20 form with this side wall 24 a housing 27 in which the cage 10 can slide along the X axis at the time of its insertion and which then ensures the maintenance lateral of this cage 10 and therefore of the movable contact bridge 11.

    Il est bien entendu que l'on peut sans sortir du cadre de l'invention, imaginer des variantes et des perfectionnements de détail et de même envisager l'emploi de moyens équivalents.It is understood that one can without departing from the scope of the invention, imagine variations and refinements of detail and even consider the use of equivalent means.
