MODULE DE COUPURE POUR APPAREIL ELECTRIQUE ET APPAREIL ELECTRIQUE EQUIPE D'UN TEL MODULECUTTING MODULE FOR ELECTRICAL APPARATUS AND ELECTRIC APPARATUS EQUIPPED WITH SUCH A MODULE
Domaine technique :Technical area :
La présente invention concerne un module de coupure pour appareil électrique comprenant au moins un boîtier pourvu d'au moins quatre contacts fixes, dont un contact fixe amont destiné à être couplé à une borne de raccordement d'entrée, un contact fixe aval destiné à être couplé à une borne de raccordement de sortie et deux contacts fixes intermédiaires reliés électriquement entre-eux par un fusible ou un pontage, et d'au moins deux paires de contacts mobiles, dont une paire de contacts mobiles amont et une paire de contacts mobiles aval, destinées à être couplées à un organe de commande pour être déplacées entre au moins une position enclenchée dans laquelle les contacts mobiles sont en contact avec les contacts fixes et le circuit électrique est fermé et une position déclenchée dans laquelle ils ne sont pas en contact avec les contacts fixes et le circuit électrique est ouvert.The present invention relates to a cut-off module for electrical apparatus comprising at least one housing provided with at least four fixed contacts, including an upstream fixed contact intended to be coupled to an input connection terminal, a downstream fixed contact intended to be coupled to an output connection terminal and two intermediate fixed contacts electrically connected to each other by a fuse or bridging, and at least two pairs of movable contacts, including a pair of upstream movable contacts and a pair of downstream movable contacts , to be coupled to a control member to be displaced between at least one engaged position in which the movable contacts are in contact with the fixed contacts and the electrical circuit is closed and a triggered position in which they are not in contact with the fixed contacts and the electrical circuit is open.
L'invention concerne également un appareil électrique comportant au moins un module de coupure tel que défini ci-dessus et au moins un module de commande comportant ledit organe de commande.The invention also relates to an electrical apparatus comprising at least one breaking module as defined above and at least one control module comprising said control member.
Technique antérieure :Prior art:
Les appareils électriques concernés par la présente invention sont notamment des interrupteurs, des interrupteurs fusibles, des disjoncteurs, et tout appareil électrique de coupure, mono ou polyphasé, utilisé pour distribuer et contrôler l'énergie électrique d'une installation de quelques dizaines à quelques centaines d'ampères. La publication FR-2.818.434 du même titulaire décrit un exemple d'appareil électrique pourvu d'un mécanisme à quadruple coupure dans lequel le mouvement de rotation de l'organe de commande est transformé en un mouvement de translation des contacts mobiles par un système à came coopérant avec des coulisseaux. Ce mécanisme est doublé pour doubler les contacts mobiles et permettre la circulation de courants élevés avec des pièces d'encombrement réduit. Dans ce principe, les vitesses d'enclenchement et de déclenchement ne sont pas suffisamment rapides pour limiter la formation des arcs électriques à chaque changement d'état de l'appareil compte-tenu de la cinématique complexe reliant l'organe de commande aux contacts mobiles. Il s'ensuit une usure prématurée des zones de contact électriques et des effets parasites dans les états transitoires.The electrical devices concerned by the present invention are in particular switches, fuse switches, circuit breakers, and any single or multiphase electrical switching device used to distribute and control the electrical energy of an installation from a few tens to a few hundred. amperes. The publication FR-2.818.434 by the same holder describes an example of an electrical apparatus provided with a quadruple-cut mechanism in which the rotational movement of the control is transformed into a translational movement of the movable contacts by a cam system cooperating with sliders. This mechanism is doubled to double the movable contacts and allow the circulation of high currents with parts of reduced size. In this principle, the latching and tripping speeds are not fast enough to limit the formation of arcing at each change of state of the apparatus taking into account the complex kinematics connecting the control member to the moving contacts. . This results in premature wear of the electrical contact areas and spurious effects in the transient states.
Exposé de l'invention :Presentation of the invention
Le but de la présente invention est de proposer un module de coupure ayant un meilleur comportement électromagnétique grâce à une cinématique de fonctionnement autorisant des vitesses d'enclenchement et de déclenchement plus rapides pour réduire les arcs électriques et diminuer leurs effets. Un autre but de l'invention est de proposer un module de coupure dit universel, d'un prix de revient réduit, pouvant être combiné à d'autres modules de coupure identiques pour couvrir plusieurs versions d'appareils électriques de coupure, mais aussi pour réaliser des appareils électriques différents, tels que des interrupteurs simples, des commutateurs simples ou à recouvrement, etc.The object of the present invention is to provide a breaking module having a better electromagnetic behavior through an operating kinematic allowing faster engagement and tripping speeds to reduce arcing and reduce their effects. Another object of the invention is to propose a so-called universal cut-off module, of a reduced cost price, that can be combined with other identical cut-off modules to cover several versions of electrical cut-off devices, but also to make different electrical devices, such as simple switches, simple or overlapping switches, etc.
Dans ce but, l'invention concerne un module de coupure du genre indiqué en préambule, caractérisé en ce que les deux paires de contacts mobiles sont montées mobiles en rotation autour d'un même axe de rotation et sont couplées par un mécanisme d'entraînement en rotation agencé pour inverser le sens de rotation d'une paire par rapport à l'autre paire de sorte qu'en position enclenchée le courant circule du contact fixe amont vers le contact fixe aval en décrivant une boucle croisée. Cette cinématique simple permet d'obtenir une vitesse de coupure plus élevée limitant ainsi la formation des arcs électriques. De plus, la rotation inverse des contacts mobiles, qui génère une circulation du courant en boucle croisée, a pour effet d'inverser et donc d'annuler les champs magnétiques induits par le courant dans les deux branches de la boucle.For this purpose, the invention relates to a cut-off module of the type indicated in the preamble, characterized in that the two pairs of movable contacts are rotatably mounted around the same axis of rotation and are coupled by a drive mechanism. in rotation arranged to reverse the direction of rotation of one pair relative to the other pair so that in the engaged position the current flows from the upstream fixed contact to the downstream fixed contact by describing a cross-loop. This simple kinematics makes it possible to obtain a higher cut-off speed thus limiting the formation of electric arcs. In addition, the inverse rotation of the moving contacts, which generates a cross-loop current flow, has the effect of reversing and thus canceling the magnetic fields induced by the current in the two branches of the loop.
Dans une forme de réalisation préférée, les contacts fixes sont disposés par paire dans deux chambres de coupure, superposées dans le boîtier et isolées électriquement l'une de l'autre, par au moins une paroi intermédiaire destinée à être traversée par l'organe de commande. Les contacts fixes d'une même paire et les contacts mobiles d'une même paire sont avantageusement diamétralement opposés par rapport à l'axe de rotation.In a preferred embodiment, the fixed contacts are arranged in pairs in two breaking chambers, superimposed in the housing and electrically insulated from each other, by at least one intermediate wall intended to be traversed by the control member. ordered. The fixed contacts of the same pair and the movable contacts of the same pair are advantageously diametrically opposed with respect to the axis of rotation.
Au moins une paire de contacts mobiles est destinée à être couplée à l'organe de commande rotatif, l'autre paire de contacts mobiles étant entraînée en rotation en sens inverse par ledit mécanisme d'entraînement à engrenage. Ce mécanisme d'entraînement peut comporter au moins deux roues dentées identiques et parallèles, chaque roue dentée étant couplée à une paire de contacts mobiles, et au moins un pignon ou au moins deux pignons diamétralement opposés engrenant les deux roues dentées.At least one pair of movable contacts is adapted to be coupled to the rotary controller, the other pair of movable contacts being rotated in opposite direction by said gear drive mechanism. This drive mechanism may comprise at least two identical and parallel toothed wheels, each toothed wheel being coupled to a pair of movable contacts, and at least one pinion or at least two diametrically opposite pinions meshing with the two toothed wheels.
De préférence au moins les contacts mobiles ou fixes comportent au moins deux lames électriquement conductrices formant une pince destinée à enserrer la lame des autres contacts fixes ou mobiles. Dans ce cas, au moins les contacts fixes ou mobiles ont des bords d'attaque biseautés facilitant leur emboîtement en position enclenchée avec les autres contacts mobiles ou fixes.Preferably at least the mobile or fixed contacts comprise at least two electrically conductive blades forming a clamp for gripping the blade of the other fixed or movable contacts. In this case, at least the fixed or mobile contacts have beveled leading edges facilitating their interlocking in the engaged position with the other movable or fixed contacts.

Un contact fixe amont 4a destiné à être couplé à une borne de raccordement d'entrée 40a (cf. fig. 3) et un contact fixe intermédiaire 4a' sont disposés dans une chambre de coupure dite amont 2a. Un contact fixe aval 4b destiné à être couplé à une borne de raccordement de sortie 40b (cf. fig. 3) et un contact fixe intermédiaire 4b' sont disposés dans l'autre chambre de coupure dite aval 2b. Les deux contacts fixes 4a', b' intermédiaires sont reliés électriquement entre eux par un fusible 5 extérieur au boîtier 2. Ils peuvent également être reliés entre eux par un pontage selon la version d'appareil électrique à réaliser. Le fusible 5 est monté sur le boîtier 2 et connecté aux contacts fixes intermédiaires 4a',b' de manière connue par des portes-fusibles 5'.This breaking module 1 comprises four fixed contacts 4a, a ', b, b', separated into two pairs 4a, a 'and 4b, b', each pair being arranged in a breaking chamber 2a, 2b. An upstream fixed contact 4a intended to be coupled to an input connection terminal 40a (see FIG 3) and an intermediate fixed contact 4a 'are arranged in a so-called upstream breaking chamber 2a. A downstream fixed contact 4b intended to be coupled to an output connection terminal 40b (see FIG 3) and an intermediate fixed contact 4b 'are arranged in the other so-called downstream interrupting chamber 2b. The two intermediate fixed contacts 4a ', b' are electrically interconnected by a fuse 5 outside the housing 2. They can also be connected to each other by a bridging according to the version of the electrical appliance to be produced. The fuse 5 is mounted on the housing 2 and connected to the intermediate fixed contacts 4a ', b' in a known manner by fuse holders 5 '.
Ce module de coupure 1 comporte également deux paires de contacts mobiles 6a,a' et 6b,b', dont une paire de contacts mobiles amont 6a, a' est disposée dans la chambre de coupure amont 2a pour coopérer avec la paire de contacts fixes amont 4a, a' et une paire de contacts mobiles aval 6b,b' est disposée dans la chambre de coupure aval 2b pour coopérer avec la paire de contacts fixes aval 4b,b\ Les deux paires de contacts mobiles 6a,a',b,b' sont montées mobiles en rotation autour d'un même axe de rotation A et sont couplées entre elles par un mécanisme d'entraînement 7 en rotation, agencé pour inverser le sens de rotation d'une paire par rapport à l'autre paire. Une des paires de contacts mobiles 6b,b' est couplée directement à l'organe de commande de l'appareil électrique, constitué notamment d'un axe de commande rotatif disposé dans ledit axe de rotation A et emboîté dans un logement 70 de forme complémentaire. Cette liaison peut aussi être effectuée de manière indirecte selon le type d'organe de commande. Cet organe de commande combiné au mécanisme d'entraînement 7 permet de déplacer les paires de contacts mobiles 6a,a',b,b' entre au moins une position enclenchée dans laquelle ils sont en contact avec les contacts fixes 4a,a',b,b' et le circuit électrique est fermé et une position déclenchée dans laquelle ils ne sont pas en contact avec les contacts fixes et le circuit électrique est ouvert. La rotation inversée des deux paires de contacts mobiles 6a,a',b,b' fait en sorte qu'en position enclenchée, le courant circule du contact fixe amont 4a vers le contact fixe aval 4b en décrivant une boucle croisée B telle que représentée par le trait mixte sur la figure 1.This breaking module 1 also comprises two pairs of movable contacts 6a, a 'and 6b, b', a pair of upstream movable contacts 6a, a 'is disposed in the upstream cutoff chamber 2a to cooperate with the pair of fixed contacts. upstream 4a, a 'and a pair of downstream movable contacts 6b, b' is disposed in the downstream breaking chamber 2b to cooperate with the pair of downstream fixed contacts 4b, b \ The two pairs of movable contacts 6a, a ', b , b 'are rotatably mounted around a same axis of rotation A and are coupled together by a rotating drive mechanism 7, arranged to reverse the direction of rotation of one pair relative to the other pair. One of the pairs of movable contacts 6b, b 'is coupled directly to the control member of the electrical apparatus, consisting in particular of a rotary control shaft disposed in said axis of rotation A and fitted into a housing 70 of complementary shape . This connection can also be performed indirectly depending on the type of control member. This control member combined with the drive mechanism 7 makes it possible to move the pairs of movable contacts 6a, a ', b, b' between at least one engaged position in which they are in contact with the fixed contacts 4a, a ', b , b 'and the electric circuit is closed and a triggered position in which they are not in contact with the fixed contacts and the electrical circuit is open. The inverted rotation of the two pairs of movable contacts 6a, a ', b, b' ensures that in the on position, the current flows from the upstream fixed contact 4a to the downstream fixed contact 4b by describing a cross-loop B as represented by the dashed line in Figure 1.
Les contacts fixes 4a,a' et 4b,b' d'une même paire et les contacts mobiles 6a,a' et 6b,b' d'une même paire sont diamétralement opposés par rapport à l'axe de rotation A. Ils présentent des zones de contact électriques planes disposées dans des plans perpendiculaires à cet axe de rotation A et aptes à glisser les unes par rapport aux autres lors des changements de position. Ils sont notamment formés de lames électriquement conductrices. Pour assurer un bon contact électrique, les contacts mobiles 6a,a',b,b' sont formés de deux lames parallèles formant une pince destinée à enserrer la lame unique des contacts fixes 4a,a',b,b'. L'inverse est également envisageable. Pour favoriser l'emboîtement des pinces sur les lames en position enclenchée, au moins les contacts fixes 4a,a',b,b' comportent des bords d'attaque biseautés, les contacts mobiles 6a,a',b,b' pouvant également en être équipés. Dans l'exemple représenté, les contacts fixes 4a,a' et 4b,b' sont disposés dans les angles, sur les diagonales du boîtier 2 de forme carrée, et les contacts mobiles 6a,a' et 6b,b' s'étendent radialement à partir d'un moyeu central 7a, 7b d'axe A. Le mécanisme d'entraînement 7 est un mécanisme à engrenage comportant au moins deux roues dentées 71, 72 identiques et parallèles, chaque roue dentée 71, 72 étant couplée à une paire de contacts mobiles 6a,a' et 6b,b', et au moins un pignon 73 engrenant les deux roues dentées 71, 72. Dans l'exemple représenté aux figures 5 et 6, les roues dentées 71, 72 sont des couronnes solidaires du moyeu central 7a, 7b et les pignons 73 sont au nombre de quatre, répartis sur la périphérie des roues dentées 71, 72 disposés à angle droit deux à deux. Ce mécanisme d'entraînement 7 est très simple et permet dans un encombrement réduit l'inversion du sens de rotation de la deuxième paire de contacts mobiles 6a, a' par rapport à la première paire de contacts mobiles 6b,b' directement entraînée par l'organe de commande de l'appareil électrique. Bien entendu, les pignons 73 sont montés sur un porte-satellite (non représenté) fixe par rapport au boîtier 2 et les moyeux 7a, 7b sont guidés en rotation selon l'axe de rotation A par des formes complémentaires (non représentées) prévues dans le boîtier 2.The fixed contacts 4a, a 'and 4b, b' of the same pair and the movable contacts 6a, a 'and 6b, b' of the same pair are diametrically opposed with respect to the axis of rotation A. They present flat electrical contact areas disposed in planes perpendicular to this axis of rotation A and able to slide relative to each other during changes of position. They are in particular formed of electrically conductive blades. To ensure good electrical contact, the movable contacts 6a, a ', b, b' are formed of two parallel blades forming a clamp for gripping the single blade of the fixed contacts 4a, a ', b, b'. The opposite is also possible. To promote the engagement of the clamps on the blades in the engaged position, at least the fixed contacts 4a, a ', b, b' comprise beveled leading edges, the movable contacts 6a, a ', b, b' also being able to to be equipped. In the example shown, the fixed contacts 4a, a 'and 4b, b' are arranged in the corners, on the diagonals of the box 2 of square shape, and the movable contacts 6a, a 'and 6b, b' extend radially from a central hub 7a, 7b of axis A. The drive mechanism 7 is a gear mechanism having at least two identical and parallel gears 71, 72, each gear 71, 72 being coupled to a pair of movable contacts 6a, a 'and 6b, b', and at least one pinion 73 meshing with the two toothed wheels 71, 72. In the example shown in FIGS. 5 and 6, the toothed wheels 71, 72 are crowns integral with the central hub 7a, 7b and the pinions 73 are four in number, distributed on the periphery of the toothed wheels 71, 72 arranged at right angles in pairs. This drive mechanism 7 is very simple and allows in a small space the reversal of the direction of rotation of the second pair of movable contacts 6a, a 'with respect to the first pair of movable contacts 6b, b' directly driven by the control member of the electrical apparatus. Of course, the pinions 73 are mounted on a carrier (not shown) fixed to the housing 2 and the hubs 7a, 7b are guided in rotation along the axis of rotation A by complementary shapes (not shown) provided in the case 2.
Tout autre mécanisme d'entraînement permettant d'atteindre le même résultat peut convenir.Any other drive mechanism to achieve the same result may be suitable.
Le module de coupure 1 comporte un dispositif anti-arc 8 constitué de quatre séries de barrettes 80 électriquement isolantes disposées dans le boîtier 2, au moins en aval des contacts fixes 4a,a',b,b' et orientées sensiblement perpendiculairement au circuit B' du courant électrique lors du passage de la position enclenchée à la position déclenchée comme représenté à la figure 2. Ces barrettes 80 comportent une découpe en V pour ne pas interférer avec les contacts mobiles 6a,a',b,b' lors de leur rotation et permettent de limiter la formation des arcs électriques entre les contacts fixes 4a,a',b,b' et les contacts mobiles 6a,a',b,b' lors de la coupure du circuit électrique en coupant la conductivité de l'air. Possibilités d'application industrielle :The breaking module 1 comprises an anti-arc device 8 consisting of four series of electrically insulating strips 80 arranged in the housing 2, at least downstream of the fixed contacts 4a, a ', b, b' and oriented substantially perpendicularly to the circuit B electrical current when the transition from the engaged position to the triggered position as shown in Figure 2. These strips 80 comprise a V-shaped cutout to not interfere with the movable contacts 6a, a ', b, b' during their rotation and can limit the formation of arcing between the fixed contacts 4a, a ', b, b' and the movable contacts 6a, a ', b, b' during the breaking of the electrical circuit by cutting the conductivity of the air. Possibilities of industrial application:
Le module de coupure 1 selon l'invention est conçu de manière simple et économique. Son boîtier 2, sa paroi 3 intermédiaire et ses moyeux 7a, 7b sont réalisés dans des matières électriquement isolantes de préférence des matières synthétiques moulées ou injectées. Le boîtier 2 est formé de deux parties emboîtables correspondant aux deux chambres de coupure 2a, 2b. Ces deux parties intègrent les barrettes 80 formant le dispositif anti-arc 8. Les contacts fixes 4a,a',b,b' et mobiles 6a,a',b,b' sont formés de lames sensiblement rectangulaires, en matière électriquement conductrice, avec ou sans pastilles de contact électrique. Les contacts fixes 4a,a',b,b' sont rapportés dans le boîtier 2 par emboîtement dans des logements adaptés et les contacts mobiles 6a,a',b,b' sont rapportés dans les moyeux 7a, 7b par surmoulage par exemple. Bien entendu, tout autre moyen d'assemblage adapté est possible.The breaking module 1 according to the invention is designed simply and economically. Its housing 2, its intermediate wall 3 and its hubs 7a, 7b are made of electrically insulating materials, preferably molded or injected plastics. The housing 2 is formed of two interlocking parts corresponding to the two breaking chambers 2a, 2b. These two parts include the bars 80 forming the anti-arc device 8. The fixed contacts 4a, a ', b, b' and mobile 6a, a ', b, b' are formed of substantially rectangular blades, made of electrically conductive material, with or without electrical contact pads. The fixed contacts 4a, a ', b, b' are reported in the housing 2 by interlocking in suitable housings and the movable contacts 6a, a ', b, b' are reported in the hubs 7a, 7b by overmolding for example. Of course, any other suitable means of assembly is possible.
L'assemblage d'un tel module de coupure 1 peut s'effectuer de la manière suivante. Dans une première partie du boîtier 2 formant par exemple la chambre de coupure amont 2a, on met en place la paire de contacts fixes amont 4a, a' et le moyeu 7a équipé de sa paire de contacts mobiles amont 6a, a'. On place la paroi intermédiaire 3 et le porte-satellite équipé de ces pignons 73 sur le moyeu 7a. Dans la deuxième partie du boîtier 2 formant la chambre de coupure aval 2b, on met en place la paire de contacts fixes aval 4b,b' et le moyeu 7b équipé de sa paire de contacts mobiles aval 6b,b\ On superpose cette deuxième partie à la première partie et on les assemble par emboîtement forcé, vissage ou tout moyen adapté. On monte sur le boîtier 2 les porte- fusibles 5' et le fusible 5. Ce module de coupure 1 est prêt à être assemblé par superposition à d'autres modules de coupure 1 identiques et à un module de commande pour former un appareil électrique de coupure à plusieurs pôles, l'organe de commande traversant les différents modules de coupure 1 à travers les boîtiers 2 pour s'emboîter dans les logements 70 correspondants. Ce module de coupure 1 permet une utilisation simple, optimale et fiable. En position enclenchée, représentée sur les figures 1 et 3, le courant du réseau d'alimentation électrique entre dans le module de coupure 1 par une borne de raccordement d'entrée couplée au contact fixe amont 4a. Il traverse le fusible 5 par l'intermédiaire de la paire de contact mobile amont 6a,a' et d'un premier contact fixe intermédiaire 4a' à l'intérieur de la chambre de coupure amont 2a. Il est dirigé dans une installation électrique par une borne de raccordement de sortie couplée au contact fixe aval 4b en transitant par le second contact fixe intermédiaire 4b' et la paire de contact mobile aval 6b,b' orientée dans une direction perpendiculaire à celle de la paire de contact mobile amont 6a,a'. Le trajet du courant en position enclenchée forme la boucle croisée représentée par le trait fléché B.The assembly of such a breaking module 1 can be carried out as follows. In a first part of the housing 2 forming, for example, the upstream cutoff chamber 2a, the pair of upstream fixed contacts 4a, a 'and the hub 7a equipped with its pair of upstream movable contacts 6a, a' are put in place. The intermediate wall 3 and the planet carrier equipped with these pinions 73 are placed on the hub 7a. In the second part of the casing 2 forming the downstream cut-off chamber 2b, the pair of downstream fixed contacts 4b, b 'and the hub 7b equipped with its pair of downstream movable contacts 6b, b1 are superimposed. in the first part and assembled by forced fitting, screwing or any suitable means. The fuse holders 5 'and the fuse 5 are mounted on the casing 2. This cut-off module 1 is ready to be assembled by superposing on other identical cut-off modules 1 and on a control module to form an electrical appliance. cut to several poles, the control member passing through the different breaking modules 1 through the housings 2 to fit into the corresponding housing 70. This cut-off module 1 allows a simple, optimal and reliable use. In the engaged position, shown in Figures 1 and 3, the power supply network current enters the breaking module 1 by an input connection terminal coupled to the upstream fixed contact 4a. It passes through the fuse 5 via the upstream movable contact pair 6a, a 'and a first intermediate fixed contact 4a' inside the upstream cut-off chamber 2a. It is directed in an electrical installation by an output connection terminal coupled to the downstream fixed contact 4b passing through the second intermediate fixed contact 4b 'and the downstream movable contact pair 6b, b' oriented in a direction perpendicular to that of the upstream moving contact pair 6a, a '. The path of the current in the engaged position forms the cross-loop represented by the arrow mark B.
Pour passer en position déclenchée, représentée par les figures 2 et 4, la paire de contacts mobiles aval 6b,b' est entraînée en rotation suivant l'axe de rotation A dans le sens inverse des aiguilles d'une montre représenté par les flèches C en prise directe avec l'organe de commande de l'appareil électrique. Ce mouvement de rotation est transmis et inversé par le mécanisme d'entraînement 7 à la paire de contacts mobiles amont 6a, a' qui est entraînée simultanément et sans inertie dans le sens des aiguilles d'une montre représenté par les flèches C. Lorsque les contacts mobiles 6a,a',b,b' quittent les contacts fixes 4a,a',b,b', le courant continue à circuler pendant un laps de temps très court formant des arcs électriques entre lesdits contacts. Le trajet du courant pendant cet état transitoire forme un oméga représenté par le trait fléché B'. La cinématique du mouvement des contacts mobiles 6a,a',b,b', étant simple, directe, sans perte et sans inertie, permet d'obtenir une vitesse de coupure très rapide par déplacement rotatif des contacts mobiles 6a,a',b,b' par rapport aux contacts fixes 4a,a',b,b'. L'effet immédiat observé est l'étirement très rapide des arcs électriques donc une disparition également plus rapide de ces arcs, en comparaison des mécanismes de coupure par translation. De ce fait, les effets secondaires néfastes provoqués par ces arcs électriques sont nettement amoindris voire insignifiants. De plus, la présence des barrettes 80 sur ce trajet B' tend à couper la conductivité de l'air, ce qui limite voire supprime la création des arcs électriques. Le résultat contribue à obtenir un module de coupure 1 beaucoup plus performant et d'une grande fiabilité dans le temps.To move to the triggered position, represented by FIGS. 2 and 4, the pair of moving downstream contacts 6b, b 'is rotated along the axis of rotation A in the counterclockwise direction represented by the arrows C. in direct contact with the control member of the electrical apparatus. This rotational movement is transmitted and inverted by the driving mechanism 7 to the upstream movable contact pair 6a, a 'which is driven simultaneously and without inertia in the clockwise direction represented by the arrows C. When the movable contacts 6a, a ', b, b' leave the fixed contacts 4a, a ', b, b', the current continues to flow for a very short period of time forming electric arcs between said contacts. The current path during this transient state forms an omega represented by the arrow line B '. The kinematics of the movement of the movable contacts 6a, a ', b, b', being simple, direct, without loss and without inertia, makes it possible to obtain a very fast breaking speed by rotary displacement of the movable contacts 6a, a ', b , b 'with respect to the fixed contacts 4a, a', b, b '. The immediate effect observed is the very fast stretching of the electric arcs, thus also a faster disappearance of these arcs, in comparison with the mechanisms of cut by translation. As a result, the harmful side effects caused by these electric arcs are clearly diminished or even insignificant. Of Moreover, the presence of the bars 80 on this path B 'tends to cut the conductivity of the air, which limits or even eliminates the creation of arcing. The result contributes to obtain a module of cutoff 1 much more powerful and of a great reliability in the time.
Ce module de coupure 1 a également été conçu pour permettre la réalisation d'autres appareils électriques en utilisant les mêmes composants, contribuant à réduire nettement les prix de revient. Les figures 7 à 9 illustrent, par trois exemples, les possibilités offertes par un tel module de coupure 1 dont la conception nouvelle peut être qualifiée d'universelle.This cut-off module 1 has also been designed to allow the realization of other electrical appliances using the same components, helping to significantly reduce the cost. FIGS. 7 to 9 illustrate, by three examples, the possibilities offered by such a cut-off module 1 whose new design can be described as universal.
La figure 7 illustre un interrupteur simple 10 à deux positions 0-1. Il est formé d'une seule partie du boîtier 2 par exemple de la chambre de coupure aval 2b et ne comporte qu'une paire de contacts fixes 4b,b' et qu'une paire de contacts mobiles 6b,b', le moyeu 7b étant destiné à être couplé à un organe de commande.Figure 7 illustrates a simple switch 10 with two positions 0-1. It is formed of a single part of the housing 2 for example of the downstream breaking chamber 2b and has only one pair of fixed contacts 4b, b 'and a pair of movable contacts 6b, b', the hub 7b being intended to be coupled to a control member.
La figure 8 illustre un commutateur li a trois positions I-0-II. Il est formé à partir du module de coupure 1 dans lequel on a remplacé le fusible 5 par un pontage 9, on a supprimé le mécanisme d'entraînement 7 et on a solidarisé les moyeux 7a et 7b qui sont destinés à être couplés à un organe de commande. Les deux contacts fixes 4a et 4b forment les deux contacts amont du commutateur couplés chacun à un réseau d'alimentation et le pontage 9 forme un contact aval commun couplé à l'installation électrique.Figure 8 illustrates a three-position li switch I-O-II. It is formed from the breaking module 1 in which the fuse 5 has been replaced by a bridging 9, the drive mechanism 7 has been removed and the hubs 7a and 7b which are intended to be coupled to an element have been secured. control. The two fixed contacts 4a and 4b form the two upstream contacts of the switch each coupled to a supply network and the bridging 9 forms a common downstream contact coupled to the electrical installation.

Il est formé à partir du module de coupure 1 dans lequel on a remplacé le fusible 5 par un pontage 9, on a supprimé le mécanisme d'entraînement 7 et on a solidarisé les moyeux 7a et 7b destinés à être couplés à un organe de commande, on a remplacé les contacts fixes simples par des contacts fixes pourvus d'une zone de recouvrement. Les deux contacts fixes 4a et 4b forment deux contacts amont couplés chacun à un réseau d'alimentation et le pontage 9 forme un contact aval commun couplé à l'installation électrique.Fig. 9 illustrates a four-position overlap switch 12 I-I + II-II-0.
