Le disjoncteur à came mono-piste est présenté en mode de connexion fermée en figure 1A, c'est-à-dire que le premier connecteur électrique mâle 6' est inséré dans le second connecteur électrique femelle 7' afin de créer un contact d'arc et le second connecteur électrique mâle 7 est inséré dans le premier connecteur électrique femelle 6 afin de créer un contact électrique principal.The single-track cam circuit breaker is shown in closed connection mode in Figure 1A , i.e., the first male electrical connector 6 'is inserted into the second female electrical connector 7' to create a contact arc and the second male electrical connector 7 is inserted into the first female electrical connector 6 to create a main electrical contact.

La figure 1B présente ledit disjoncteur dans un mode de connexion ouverte (ou connexion fermée) intermédiaire situé entre le mode de connexion fermée et le mode de connexion ouverte. Le disjoncteur est configuré de façon à ce que la désolidarisation complète du premier connecteur électrique femelle 6 du second connecteur électrique mâle 7 se produise avant la désolidarisation complète du premier connecteur électrique mâle 6' du second connecteur électrique femelle 7', de façon à ce que cette dernière crée une rupture de contact sous arc électrique canalisé par ladite tuyère 10.The Figure 1B presents said circuit breaker in an intermediate open connection mode (or closed connection) located between the closed connection mode and the open connection mode. The circuit breaker is configured so that the complete disengagement of the first female electrical connector 6 of the second male electrical connector 7 occurs before the complete disengagement of the first male electrical connector 6 'of the second female electrical connector 7', so that the latter creates a contact break under an electric arc channeled by said nozzle 10.

La figure 1C montre le disjoncteur en mode de connexion ouverte, dans lequel les connecteurs mâles et femelles sont tous séparés les uns des autres, leur séparation étant due à leur interaction mécanique via la came mono-piste 3.The figure 1C shows the breaker in open connection mode, in which the male and female connectors are all separated from each other, their separation being due to their mechanical interaction via the mono-track cam 3.

Comme on le sait, la conception d'un tel disjoncteur nécessite généralement un compromis entre vitesse d'actionnement et robustesse. Le mécanisme à came présenté à la figure 1 est avantageux de par sa fiablité/robustesse et permet la mise en mouvement d'un ensemble mécanique relativement important, c'est-à-dire ici le premier connecteur électrique femelle 6 et le premier connecteur électrique mâle 6'.As is known, the design of such a circuit breaker generally requires a compromise between operating speed and robustness. The cam mechanism presented to the figure 1 is advantageous because of its reliability / robustness and allows the setting in motion of a relatively large mechanical assembly, that is to say here the first female electrical connector 6 and the first male electrical connector 6 '.

On notera toutefois que le rapport entre, d'une part la vitesse de déconnexion du second connecteur électrique mâle 7 et du premier connecteur électrique femelle 6, et d'autre part, la vitesse de déconnexion du premier connecteur électrique mâle 6' et du second connecteur électrique femelle 7' vaut approximativement 1. Ce rapport proche de 1 pour les vitesses de déconnexion susmentionnées augmente la durée de coupure d'arc et donc diminue la fonction protectrice du disjoncteur qui met dès lors plus de temps pour interrompre un courant électrique en cas d'incidents.It will be noted, however, that the ratio between, on the one hand, the disconnection speed of the second male electrical connector 7 and the first female electrical connector 6, and, on the other hand, the disconnection speed of the first male electrical connector 6 'and the second Female electrical connector 7 'is approximately 1. This ratio close to 1 for the above-mentioned disconnection speeds increases the arc breaking time and therefore reduces the protective function of the circuit breaker, which therefore takes longer to interrupt an electric current in case incidents.

Pour atténuer les champs électriques, réduire la vitesse de déclenchement et protéger les contacts électriques, il est connu d'utiliser un écran.To attenuate the electric fields, reduce the triggering speed and protect the electrical contacts, it is known to use a screen.

Sur la Figure 1, le premier connecteur électrique femelle 6 est en fait recouvert par une couche de matériau diélectrique 6a formant donc un écran tubulaire.On the Figure 1 , the first female electrical connector 6 is in fact covered by a layer of dielectric material 6a thus forming a tubular screen.

Le EP 2 510 530 décrit un disjoncteur haute tension comprenant un premier ensemble "drive side" avec un contact principal mâle et un contact d'arc femelle coopérant avec un deuxième ensemble comprenant un contact principal femelle et un contact d'arc mâle, les deux ensemble étant mobiles de façon à s'écarter ou être mis en contact, sélectivement, pour une connexion ouverte ou fermée. Dans le deuxième ensemble, le contact principal femelle et le contact d'arc mâle sont mobiles par rapport à un tube isolant central. Un écran est interposé entre le contact d'arc mâle et le contact principal femelle. L'écran est en fait positionné à l'intérieur du carter support du contact principal femelle, et est déplacé grâce à des ressorts lors d'une manoeuvre d'ouverture par l'intermédiaire de tiges.The EP 2 510 530 discloses a high-voltage circuit breaker comprising a first "drive side" assembly with a male main contact and a female arc contact cooperating with a second assembly comprising a female main contact and a male arc contact, both of which are movable together. away or selectively contacted for an open or closed connection. In the second set, the main female contact and the male arc contact are movable relative to a central insulating tube. A screen is interposed between the male arc contact and the female main contact. The screen is actually positioned inside the support housing of the female main contact, and is moved by springs during an opening maneuver via rods.

La solution proposée par le EP 2 510 530 est complexe sur le plan de sa réalisation. L'écran et son mécanisme doivent être intégrés dans un espace réduit, sous le carter support du contact d'arc mâle.The solution proposed by EP 2 510 530 is complex in terms of its realization. The screen and its mechanism must be integrated in a small space under the support housing of the male arc contact.

Les documents EP 0 809 269 A2 et DE 10 2013 200913 A1 décrivent d'autres réalisations pertinentes de disjoncteurs dans le cadre de la présente invention. Le document EP0 809 269 A2 divulgue un disjoncteur selon le préambule de la revendication 1.The documents EP 0 809 269 A2 and DE 10 2013 200913 A1 describe other relevant embodiments of circuit breakers in the context of the present invention. The document EP0 809 269 A2 discloses a circuit breaker according to the preamble of claim 1.

Un but de la présente invention est de proposer un disjoncteur de conception robuste et avec une protection de contact d'arc améliorée, en particulier pour une application haute tension, par exemple dans le cas d'un disjoncteur ou sectionneur sous poste d'enveloppe métallique de type GIS.An object of the present invention is to provide a circuit breaker of robust design and with improved arc contact protection, in particular for a high voltage application, for example in the case of a circuit breaker or disconnector under metal envelope station type GIS.

Ce but est atteint par un disjoncteur selon la revendication 1.This object is achieved by a circuit breaker according to claim 1.

La présente invention propose en particulier un disjoncteur comprenant une partie semi-mobile (pin side) avec un premier connecteur électrique fixe faisant office de contact principal et un premier autre connecteur électrique mobile faisant office de contact d'arc ainsi qu'un écran mobile réalisé en aluminium ou en alliage métallique léger, entourant, à distance radiale, au moins en partie la portion d'extrémité du premier autre connecteur électrique. Un mécanisme d'actionnement, entrainé par la partie mobile (drive side) est configuré pour déplacer de manière coordonnée l'écran mobile et le premier autre connecteur électrique lors de son déplacement de la position fermée à la position ouverte du disjoncteur, de telle sorte que l'écran entoure la portion d'extrémité du premier autre connecteur électrique sur toute la course du premier autre connecteur électrique.The present invention proposes in particular a circuit breaker comprising a semi-mobile part (pin side) with a first fixed electrical connector acting as a main contact and a first other movable electrical connector acting as an arc contact as well as a mobile screen made aluminum or light metal alloy, surrounding, at a radial distance, at least partly the end portion of the first other electrical connector. An actuating mechanism, driven by the mobile part (drive side) is configured to move in a coordinated manner the mobile screen and the first other electrical connector when moving from the closed position to the open position of the circuit breaker, so that the screen surrounds the end portion of the first other electrical connector over the entire path of the first other electrical connector.

Conformément à l'invention, le disjoncteur comprend :

  • une embase de support ;
  • un premier connecteur électrique et un premier autre connecteur électrique, ledit premier autre connecteur électrique étant entraînable en mouvement par rapport à ladite embase au moyen d'un mécanisme d'actionnement;
  • un second connecteur électrique connectable électriquement au premier connecteur électrique et un second autre connecteur électrique connectable électriquement audit premier autre connecteur électrique ;
  • ledit mécanisme d'actionnement étant couplé mécaniquement audit second connecteur électrique ou audit second autre connecteur électrique de sorte à entraîner le mécanisme d'actionnement lors de la séparation du second connecteur électrique, respectivement dudit second autre connecteur électrique. Le disjoncteur est caractérisé par un écran mobile réalisé en aluminium ou en alliage métallique léger et entourant, à distance radiale, au moins en partie la portion d'extrémité du premier autre connecteur électrique, le mécanisme d'actionnement étant conçu pour déplacer de manière coordonnée l'écran mobile et le premier autre connecteur électrique lors de son déplacement de la position fermée à ouverte du disjoncteur, de telle sorte que l'écran entoure la portion d'extrémité du premier autre connecteur électrique pendant toute sa course.
According to the invention, the circuit breaker comprises:
  • a support base;
  • a first electrical connector and a first other electrical connector, said first other electrical connector being drivable in motion relative to said base by means of an actuating mechanism;
  • a second electrical connector electrically connectable to the first electrical connector and a second other electrical connector electrically connectable to said first other electrical connector;
  • said actuating mechanism being mechanically coupled to said second electrical connector or second second electrical connector so as to drive the actuating mechanism upon separation of the second electrical connector, respectively said second electrical connector. The circuit breaker is characterized by a movable screen made of aluminum or light metal alloy and surrounding, at a radial distance, at least in part the end portion of the first other electrical connector, the actuating mechanism being designed to move in a coordinated manner the movable screen and the first other electrical connector when moving from the closed to open position of the circuit breaker, so that the screen surrounds the end portion of the first other electrical connector throughout its stroke.

Ainsi, dans le présent disjoncteur, l'extrémité du premier autre connecteur électrique (contact d'arc mâle) venant en contact avec le deuxième autre connecteur électrique est en permanence protégée au moyen de l'écran mobile qui permet la répartition de champ électrique. La position relative de cet écran par rapport au premier autre connecteur électrique est gérée de manière coordonnée par le mécanisme d'actionnement, garantissant une protection pendant toute la course.Thus, in the present circuit breaker, the end of the first other electrical connector (male arc contact) coming into contact with the second other electrical connector is permanently protected by means of the movable screen which allows the distribution of electric field. The relative position of this screen relative to the first other electrical connector is managed in a coordinated manner by the actuating mechanism, ensuring protection throughout the race.

En outre, le premier autre connecteur électrique et l'écran mobile sont entraînés par le moyen d'actionnement lequel est à son tour entraîné par un moyen moteur unique, de préférence le second connecteur électrique (typiquement via une tuyère de soufflage d'arc), ce qui simplifie la mise en oeuvre.In addition, the first other electrical connector and the movable screen are driven by the actuating means which is in turn driven by a single motor means, preferably the second electrical connector (typically via an arc-blowing nozzle). which simplifies the implementation.

Le disjoncteur selon l'invention est particulièrement adapté aux moyennes et hautes tensions, et est en particulier destiné à alimenter en courant électrique un dispositif électrique, ledit disjoncteur étant dit « ouvert », ou également « en mode de connexion ouverte », lorsqu'il interrompt ou coupe le courant alimentant ledit dispositif électrique, et « fermé », ou également « en mode de connexion fermée » lorsqu'il autorise l'alimentation en courant dudit dispositif électrique.The circuit breaker according to the invention is particularly suitable for medium and high voltages, and is in particular intended to supply electrical current to an electrical device, said circuit breaker being said to be "open", or also "in open connection mode", when interrupts or cuts the current supplying said electrical device, and "closed", or also "in closed connection mode" when it allows the power supply of said electrical device.

Différents modes de réalisation de l'invention sont décrits par la suite ainsi que dans les revendications dépendantes.Various embodiments of the invention are described later as well as in the dependent claims.

Selon une variante de réalisation, le mécanisme d'actionnement est conçu pour déplacer simultanément et à la même vitesse l'écran mobile et le premier autre connecteur électrique. La position relative entre l'écran mobile et le premier autre connecteur électrique est donc fixe.According to an alternative embodiment, the actuating mechanism is designed to move simultaneously and at the same speed the mobile screen and the first other electrical connector. The relative position between the mobile screen and the first other electrical connector is fixed.

Selon une autre exécution, le mécanisme d'actionnement est conçu de telle sorte que le contrôle du déplacement est asynchrone, le premier autre connecteur électrique étant entraîné à une vitesse supérieure à celle de l'écran mobile. Dans cette variante, le mécanisme d'actionnement comprend des sous ensembles d'actionnement désynchronisés, mais mis en oeuvre par la force d'entraînement (fournie typiquement par la partie mobile, resp. la tuyère de soufflage). De préférence, le mécanisme d'actionnement est conçu de sorte qu'à partir d'un certain point d'actionnement de l'écran mobile, le premier autre connecteur électrique est entraîné à une vitesse supérieure, de sorte à accroitre la distance relative entre le bord avant de l'écran mobile et l'extrémité du premier autre connecteur électrique, ceci afin de faire baisser les contraintes diélectriques.According to another embodiment, the actuating mechanism is designed such that the displacement control is asynchronous, the first other electrical connector being driven at a speed greater than that of the moving screen. In this variant, the actuating mechanism comprises desynchronized actuation subassemblies, but implemented by the driving force (typically provided by the moving part, or the blowing nozzle). Preferably, the actuating mechanism is designed such that from a certain point of actuation of the movable screen, the first other electrical connector is driven at a higher speed, so as to increase the relative distance between the front edge of the mobile screen and the end of the first other electrical connector, in order to lower the dielectric stress.

Le disjoncteur selon l'invention est notamment illustré en figure 2 selon un premier mode de réalisation. Le disjoncteur comprend préférentiellement :

  1. a) en particulier dans une première partie dite « partie semi-mobile » ou « pin side », identifiée PS sur le dessin :
    • une embase 11 de support ;
    • un premier connecteur électrique 12 et un premier autre connecteur électrique 12', ledit premier autre connecteur électrique 12' étant entraînable en mouvement, par exemple en mouvement de translation rectiligne parallèlement à l'axe A confondu avec l'axe longitudinal du connecteur électrique 12', par rapport à ladite embase 11. Préférentiellement, le premier connecteur électrique 12 est un premier connecteur électrique femelle formant un contact principal du disjoncteur et le premier autre connecteur électrique 12' est un premier connecteur électrique mâle formant un contact d'arc, ci-après "contact d'arc mâle". Le contact d'arc mâle 12' prend généralement la forme d'une tige. Le connecteur électrique principal femelle 12 a une forme creuse généralement circulaire et entoure coaxialement le contact d'arc mâle 12'.
  2. b) en particulier dans une seconde partie dite « partie mobile » ou « drive side », désignée DS sur la figure :
    • un second connecteur électrique 14 connectable électriquement au premier connecteur électrique 12, notamment par contact avec ce dernier, et
    • un second autre connecteur électrique 14' connectable électriquement audit premier autre connecteur électrique 12', notamment par contact avec ce dernier. Préférentiellement, le second connecteur électrique 14 est un second connecteur électrique mâle formant un contact principal et le second autre connecteur électrique 14' est un second connecteur électrique femelle formant un contact d'arc, ci-après "contact d'arc femelle". Le connecteur électrique principal mâle 14 et le contact d'arc femelle 14' ont généralement des formes circulaires creuses et sont coaxiaux à l'axe A.
The circuit breaker according to the invention is particularly illustrated in figure 2 according to a first embodiment. The circuit breaker preferably comprises:
  1. a) in particular in a first part called "semi-mobile part" or "pin side", identified PS in the drawing:
    • a support base 11;
    • a first electrical connector 12 and a first other electrical connector 12 ', said first other electrical connector 12' being drivable in motion, for example in rectilinear translation movement parallel to the axis A coincides with the longitudinal axis of the electrical connector 12 ' , relative to said base 11. Preferably, the first electrical connector 12 is a first female electrical connector forming a main contact of the circuit breaker and the first other electrical connector 12 'is a first male electrical connector forming an arc contact, hereinafter after "male arc contact". The male arc contact 12 'generally takes the form of a rod. The electrical connector main female 12 has a generally circular hollow shape and coaxially surrounds the male arc contact 12 '.
  2. b) in particular in a second part called "moving part" or "drive side", designated DS in the figure:
    • a second electrical connector 14 electrically connectable to the first electrical connector 12, in particular by contact with the latter, and
    • a second other electrical connector 14 'electrically connectable to said first other electrical connector 12', in particular by contact with the latter. Preferably, the second electrical connector 14 is a second male electrical connector forming a main contact and the second other electrical connector 14 'is a second female electrical connector forming an arc contact, hereinafter "female arc contact". The male main electrical connector 14 and the female arc contact 14 'generally have hollow circular shapes and are coaxial with the axis A.

Dans la figure 2A, le disjoncteur est en connexion fermée. Les parties DS et PS sont accouplées, le contact électrique est établi entre les contacts principaux et les contacts d'arc. Pour l'ouverture du disjoncteur, c'est-à-dire pour le mettre en connexion ouverte (fig.2A), un mécanisme moteur (non montré) est prévu pour translater la partie mobile DS parallèlement à l'axe A (vers la gauche sur la figure 2) de sorte à séparer les parties DS et PS et donc les couples de contacts 12 et 14, respectivement 12' et 14'.In the Figure 2A , the circuit breaker is in closed connection. The DS and PS parts are coupled, the electrical contact is established between the main contacts and the arcing contacts. To open the circuit breaker, that is to say to put it in open connection ( 2A ), a motor mechanism (not shown) is provided to translate the mobile part DS parallel to the axis A (to the left on the figure 2 ) so as to separate the parts DS and PS and therefore the pairs of contacts 12 and 14, respectively 12 'and 14'.

Classiquement, le disjoncteur comprend une tuyère 16 (ou buse de soufflage) servant à canaliser un arc de courant susceptible d'être généré lors de la séparation du contact d'arc mâle 12' et du contact d'arc femelle 14'. La tuyère 16 sert de guide au contact d'arc male 12'. Elle comprend une partie évasée/tronconique 161, placée vers la droite sur les figures, du côté du contact d'arc mâle 12', un corps 162, central et cylindrique, et une partie élargie 163 placée du côté du contact d'arc femelle 14'.Conventionally, the circuit breaker comprises a nozzle 16 (or blowing nozzle) for channeling a current arc that can be generated during the separation of the male arc contact 12 'and the female arc contact 14'. The nozzle 16 serves as a guide to the male arc contact 12 '. It comprises a flared / frustoconical portion 16 1 positioned to the right in the figures, the side of the male arcing contact 12 ', a body 16 2, and central cylindrical portion 16 and an enlarged contact 3 positioned on the side of female bow 14 '.

Pour réduire la durée de déconnexion, le contact d'arc mâle 12' est entraînable en mouvement par rapport à l'embase au moyen d'un mécanisme d'actionnement généralement désigné 20. Le mécanisme d'actionnement 20 est de préférence lié au connecteur principal mâle 14 et est conçu de sorte qu'une déconnexion de la partie mobile DS et de la partie semi-mobile PS ou leur connexion, c'est-à-dire respectivement un éloignement ou un rapprochement jusqu'à connexion du premier connecteur électrique principal 12 avec le deuxième connecteur électrique principal 14, provoque un déplacement du contact d'arc mâle 12' en translation rectiligne selon l'axe A par rapport à l'embase 11.To reduce the disconnection time, the male arc contact 12 'is drivable in motion relative to the base by means of an actuating mechanism generally designated 20. The actuating mechanism 20 is preferably connected to the male main connector 14 and is designed so that a disconnection of the mobile part DS and the semi-mobile part PS or their connection, that is to say to say respectively a distance or a reconciliation until connection of the first main electrical connector 12 with the second main electrical connector 14, causes a displacement of the male arc contact 12 'in rectilinear translation along the axis A with respect to the base 11.

Dans la variante, le mécanisme d'actionnement 20 comprend une came mono-piste 22 montée rotative sur l'embase 11 autour d'un axe de pivot 24. Un premier bras 26 ou bielle est configuré pour entraîner en rotation la came 22. Le premier bras 26 a une extrémité couplée à la came 22 par un moyen de couplage rotatif ponctuel 28 distinct de l'axe de pivot 24 et l'autre extrémité couplée à la tuyère 16. On notera que la tuyère 16 est solidaire du connecteur électrique principal mâle 14 (et se déplace donc avec la partie mobile DS) de façon à faire pivoter la came 22 par rapport à l'embase 11 autour de l'axe de pivot 24 lors d'un retrait du connecteur électrique principal mâle 14 hors du connecteur électrique principal femelle 12 pour réaliser le mode de connexion ouverte, ou inversement, lors de son insertion dans le connecteur électrique principal femelle 12 pour réaliser le mode de connexion fermée.In the variant, the actuating mechanism 20 comprises a single-track cam 22 rotatably mounted on the base 11 around a pivot axis 24. A first arm 26 or connecting rod is configured to drive the cam 22 in rotation. first arm 26 has one end coupled to the cam 22 by a specific rotating coupling means 28 distinct from the pivot axis 24 and the other end coupled to the nozzle 16. Note that the nozzle 16 is secured to the main electrical connector male 14 (and thus moves with the movable portion DS) so as to rotate the cam 22 relative to the base 11 about the pivot axis 24 during a withdrawal of the main electrical connector male 14 out of the connector female main electrical 12 to realize the open connection mode, or vice versa, when inserted into the female main electrical connector 12 to achieve the closed connection mode.

On notera que le couplage du premier bras 26 à la tuyère 16 se fait ici via une pièce d'extension 30 fixée à la fin de la partie évasée 161 de la tuyère et s'étendant longitudinalement, le premier bras 26 étant fixé à la pièce d'extension 30 par un axe 32 autour duquel elle peut pivoter.Note that the coupling of the first arm 26 to the nozzle 16 is here via an extension piece 30 attached to the end of the flared portion 16 1 of the nozzle and extending longitudinally, the first arm 26 being fixed to the extension piece 30 by an axis 32 around which it can rotate.

Le premier bras 26 forme donc un couplage mécanique qui va permettre l'entrainement du mécanisme d'actionnement 20.The first arm 26 thus forms a mechanical coupling which will allow the actuation mechanism 20 to be driven.

Un deuxième bras 34 comprenant une première extrémité munie du premier contact d'arc mâle 12' destiné à être inséré dans (en mode de connexion fermée) ou retiré du (en mode de connexion ouverte) contact d'arc femelle 14'. Sa deuxième extrémité est entraînée par pivotement de la came 22 au moyen d'un de couplage par coulissement comprenant un coulisseau 36 solidaire de la deuxième extrémité du deuxième bras 34 et coulissant dans une piste curviligne 38 de la came 22. Le deuxième bras est guidé en translation axiale dans l'embase 11 le long de l'axe A.A second arm 34 having a first end provided with the first male arc contact 12 'to be inserted into (in closed connection mode) or removed from (in open connection mode) female arc contact 14'. Its second end is driven by pivoting of the cam 22 by means of a sliding coupling comprising a slide 36 secured to the second end of the second arm 34 and sliding in a curvilinear track 38 of the cam 22. The second arm is guided in axial translation in the base 11 along the axis A.

On appréciera que le signe de référence 40 désigne un écran mobile associé au contact d'arc mâle 12' et conçu de sorte à répartir le champ électrique afin d'en protéger l'extrémité, c'est-à-dire la portion d'extrémité proximale de la partie mobile DS et venant en contact avec le contact d'arc femelle 14'.It will be appreciated that the reference sign 40 designates a movable screen associated with the male arc contact 12 'and designed so as to distribute the electric field in order to protect the end thereof, that is to say the portion of proximal end of the mobile part DS and coming into contact with the female arc contact 14 '.

Cet écran mobile répartiteur de champ est spécifiquement dédié à la protection du contact d'arc mâle 12' et vient en supplément des écrans conventionnels, tels que par exemple :

  • écran fixe 41a de forme générale tubulaire entourant la portion arrière de la partie PS avec le mécanisme d'actionnement 20; et/ou
  • écran fixe 41b de forme générale tubulaire entourant la portion arrière de la partie DS; et/ou
  • écran 41c de forme générale tubulaire fixé autour du connecteur principal femelle 12.
This mobile field splitter screen is specifically dedicated to the protection of the male arc contact 12 'and comes in addition to conventional screens, such as for example:
  • fixed screen 41a of tubular general shape surrounding the rear portion of the PS portion with the actuating mechanism 20; and or
  • fixed screen 41b of tubular general shape surrounding the rear portion of the DS portion; and or
  • 41c generally tubular screen fixed around the female main connector 12.

On appréciera en outre que, dans la présente variante, le mécanisme d'actionnement 20 est conçu pour déplacer l'écran mobile 40 en synchronisme avec le contact d'arc mâle 12'. Ainsi, l'écran mobile 40 et le contact d'arc mâle 12' progressent simultanément et à la même vitesse dans le long de l'axe A, si bien qu'en toute position du contact d'arc mâle 12', la position relative de l'écran par rapport au contact d'arc mâle 12' reste la même. Le mécanisme proposé est ici de conception simple et ne cause pas de chocs lors de sa manoeuvre.It will be appreciated further that in the present variant, the actuating mechanism 20 is adapted to move the movable screen 40 in synchronism with the male arc contact 12 '. Thus, the movable screen 40 and the male arc contact 12 'progress simultaneously and at the same speed along the axis A, so that in any position of the male arc contact 12', the position relative of the screen relative to the male arc contact 12 'remains the same. The proposed mechanism is here of simple design and does not cause shocks during its maneuver.

Dans la variante, le deuxième bras 34 est donc couplé à l'écran mobile 40 de façon à être solidaire de ce dernier, afin d'entraîner simultanément et à la même vitesse l'écran mobile 40 et le contact d'arc mâle 12'. Ce couplage rigide est réalisé au moyen d'une bague 42 fixée à une surface périphérique (ici intérieure) de l'écran mobile 40, la bague 42 étant reliée au bras 34 par au moins deux jambes radiales (non montrés).In the variant, the second arm 34 is thus coupled to the movable screen 40 so as to be integral with the latter, in order to drive simultaneously simultaneously and at the same speed the mobile screen 40 and the male arc contact 12 ' . This rigid coupling is achieved by means of a ring 42 attached to a peripheral surface (here inner) of the mobile screen 40, the ring 42 being connected to the arm 34 by at least two radial legs (not shown).

L'écran 40 a préférablement une forme annulaire et entoure, à une relativement grande distance radiale, le contact d'arc mâle 12' de sorte à en coiffer la portion d'extrémité coopérant avec le contact d'arc femelle 14'. L'écran 40 est positionné radialement en dehors de l'espace de commutation (au-dela du connecteur principal femelle 12), et entoure donc également (au moins en partie) le connecteur principal femelle 12 et son écran 41c.The screen 40 preferably has an annular shape and surrounds, at a relatively large radial distance, the male arc contact 12 'so as to cover the end portion cooperating with the female arc contact 14'. The screen 40 is positioned radially out of the switching space (beyond the female main connector 12), and thus also surrounds (at least in part) the female main connector 12 and its screen 41c.

De préférence, l'écran 40 a une forme de capot comprenant principalement un corps annulaire de révolution, engendrée par une forme générale de U tourné vers l'axe A. L'écran est ainsi conformé de sorte à définir une paroi de fond 40a, radialement la plus éloignée de l'axe A, et deux parois latérales 40b et 40c s'étendant depuis la paroi de fond 40a en direction radiale approximativement jusqu'à hauteur du connecteur principal femelle 12. La paroi avant 40b est convexe de sorte que son bord inférieur revient vers l'intérieur, décrivant de préférence un demi-cercle pour une meilleure répartition des champs électriques. Le bord inférieur de la paroi avant 40b a un diamètre légèrement supérieur à celui de l'écran fixe 41c afin de pouvoir se déplacer le long de l'axe A sans le heurter. La paroi arrière 40c forme, à sa partie inférieure, une transition vers une portion de queue 40d en forme de manchon dont le diamètre est légèrement supérieur à celui du connecteur principal femelle 12, le manchon pénétrant sous l'écran fixe 41a. La bague 42 est fixée à l'extrémité de cette portion de queue 40d, contre la paroi intérieure.Preferably, the screen 40 has a bonnet shape mainly comprising an annular body of revolution, generated by a general U-shape turned towards the axis A. The screen is thus shaped so as to define a bottom wall 40a, radially furthest from the axis A, and two side walls 40b and 40c extending from the bottom wall 40a radially approximately to the height of the female main connector 12. The front wall 40b is convex so that its lower edge back inwards, preferably describing a semicircle for a better distribution of electric fields. The lower edge of the front wall 40b has a diameter slightly greater than that of the fixed screen 41c so as to be able to move along the axis A without knocking it. The rear wall 40c forms, at its lower part, a transition to a sleeve-shaped tail portion 40d whose diameter is slightly greater than that of the female main connector 12, the sleeve penetrating under the fixed screen 41a. The ring 42 is fixed to the end of this tail portion 40d, against the inner wall.

Comme on le voit, dans la variante de la figure 2 la paroi de fond 40a se trouve à la même distance radiale du contact d'arc mâle 12' que l'écran fixe 41a.As we see, in the variant of the figure 2 the bottom wall 40a is at the same radial distance from the male arc contact 12 'as the fixed screen 41a.

La forme de capot de l'écran 40 est optimisée pour répartir le champ électrique de sorte à protéger l'extrémité du contact d'arc mâle 12', ce qui requiert un large diamètre.The shield shape of the screen 40 is optimized to distribute the electric field so as to protect the end of the male arc contact 12 ', which requires a large diameter.

L'écran 40 est de préférence réalisé dans un matériau tel que l'aluminium ou généralement un alliage métallique léger, le même matériau pouvant être utilisé pour les autres écrans 41a, 41b et 41c. L'écran 40 est porté au potentiel de de la partie PS.The screen 40 is preferably made of a material such as aluminum or generally a light metal alloy, the same material can be used for the other screens 41a, 41b and 41c. The screen 40 is brought to the potential of the PS part.

Le déplacement de l'ensemble contact d'arc mâle 12' et écran 40 est donc réalisé de manière simultanée par la came mono-piste 22 et s'opère de la manière suivante.The displacement of the male arc contact assembly 12 'and screen 40 is therefore performed simultaneously by the single-track cam 22 and operates in the following manner.

En Fig.2A, le disjoncteur est présenté en mode de connexion fermée; le contact principal et le contact d'arc sont établis. Le coulisseau 36 se trouve à une extrémité de la piste curviligne 38 qui est la plus éloignée de l'axe de pivot 24. En fait, la came mono-piste 22 est positionnée de façon à avoir ledit moyen de couplage rotatif ponctuel 28 localisé à sa position la plus éloignée du connecteur principal femelle 12, alors que inversement le coulisseau 36 est localisé au plus près du connecteur électrique principal femelle 12.In 2A the circuit breaker is presented in closed connection mode; the main contact and the arc contact are established. The slider 36 is at one end of the curvilinear track 38 which is farthest from the pivot axis 24. In In fact, the single-track cam 22 is positioned so as to have said point rotating coupling means 28 located at its furthest position from the female main connector 12, whereas inversely the slider 36 is located as close as possible to the female main electrical connector. 12.

La Fig.2B, présente le disjoncteur dans un mode de connexion ouverte (ou connexion fermée) intermédiaire situé entre le mode de connexion fermée et le mode de connexion ouverte, c'est-à-dire lorsque le moment exercé par l'extrémité du premier bras 26 sur la came mono-piste 22 permet à celle-ci de pivoter sous un couple d'entrainement exercé par la force de traction exercée sur le moyen de couplage rotatif 28, entraînant au même moment le coulisseau 36 en déplacement le long de la piste curviligne 38 de façon à ce que ce dernier se rapproche de l'axe de pivot 24 et en même temps entraine progressivement le contact d'arc mâle 12' pour le sortir du contact d'arc femelle 14' par actionnement du second bras 34.The Fig.2B , presents the circuit breaker in an intermediate open connection mode (or closed connection) located between the closed connection mode and the open connection mode, that is to say when the moment exerted by the end of the first arm 26 on the single-track cam 22 allows it to pivot under a driving torque exerted by the traction force exerted on the rotary coupling means 28, driving at the same time the slide 36 moving along the curvilinear track 38 so that the latter approaches the pivot axis 24 and at the same time gradually causes the male arc contact 12 'to come out of the female arc contact 14' by actuating the second arm 34.

Le disjoncteur est avantageusement configuré de façon à ce que la désolidarisation complète du connecteur principal femelle 12 du connecteur principal mâle 14 se produise avant la désolidarisation complète du contact d'arc mâle 12' du contact d'arc femelle 14', de façon à ce que cette dernière crée une rupture de contact sous arc électrique canalisé par la tuyère 10. Egalement, le coulisseau 36 est configuré pour glisser dans la piste curviligne 38 dont la géométrie curviligne en forme de crochet ou « L » arrondi est adaptée pour minimiser des efforts de frictions du coulisseau avec des bords de ladite piste, et va finalement permettre un faible déplacement relatif du contact d'arc mâle au départ de la position de la Fig.2A.The circuit breaker is advantageously configured so that the complete disconnection of the main female connector 12 of the main male connector 14 occurs before the complete disengagement of the male arc contact 12 'from the female arc contact 14', so that that the latter creates a contact break under electrical arc channeled by the nozzle 10. Also, the slider 36 is configured to slide in the curvilinear track 38 whose curvilinear geometry in the form of a hook or "L" rounded is adapted to minimize efforts friction of the slide with edges of said track, and will finally allow a small relative displacement of the male arc contact at the start of the position of the 2A .

Bien entendu, l'écran mobile 40 se déplace en même temps et à la même vitesse que le contact d'arc mâle. La partie de queue 40d est rentrée sous l'écran fixe 41a de la partie PS.Of course, the mobile screen 40 moves at the same time and at the same speed as the male arc contact. The tail portion 40d is tucked under the fixed screen 41a of the PS portion.

La figure 2C montre le disjoncteur en mode de connexion ouverte, dans lequel les connecteurs principaux 12, 14 et les contacts d'arc 12'14' sont tous séparés les uns des autres, leur séparation étant due à leur interaction mécanique via la came mono-piste 22. Le coulisseau 36 a alors atteint une position finale à l'autre extrémité de la piste curviligne 38, la plus proche de l'axe de pivot 24.The Figure 2C shows the breaker in open connection mode, in which the main connectors 12, 14 and the arc contacts 12 '14' are all separated from one another, their separation being due to their mechanical interaction via the The slider 36 has then reached a final position at the other end of the curvilinear track 38, the closest to the pivot axis 24.

En considérant les figures 2A à 2C dans leur ordre inverse, il serait alors facile de comprendre le procédé opposé de (re)connexion des premiers et seconds connecteurs mâles/femelles précédemment décrits, i.e. le passage du mode de connexion ouverte au mode de connexion fermée.Considering the FIGS. 2A to 2C in their reverse order, it would then be easy to understand the opposite process of (re) connection of the first and second male / female connectors described above, ie the transition from the open connection mode to the closed connection mode.

Un deuxième mode d'exécution est représenté à la figure 3. Les parties mobile DS et semi-mobile PS sont similaires à celles de la figure 2. Les éléments identiques ou similaires sont donc désignés par les mêmes signes de référence. Comme dans la variante précédente, le contact d'arc mâle 12' et l'écran 40 sont mobiles. Toutefois, le mécanisme d'actionnement, désigné généralement 120, est de conception différente car il découple les mouvements et permet un déplacement coordonné à des vitesses différentes, ce qui permet une bonne coordination entre de la séparation des contacts d'arc et la protection diélectrique.A second embodiment is represented at figure 3 . The mobile parts DS and semi-mobile PS are similar to those of the figure 2 . Identical or similar elements are therefore designated by the same reference signs. As in the previous variant, the male arc contact 12 'and the screen 40 are movable. However, the actuating mechanism, generally designated 120, is of different design because it decouples the movements and allows a coordinated movement at different speeds, which allows a good coordination between the separation of the arcing contacts and the dielectric protection .

Le mécanisme d'actionnement 120 comprend une came mono-piste 122 montée pivotante sur l'embase 11 autour d'un axe de pivot 124.The actuating mechanism 120 comprises a single-track cam 122 pivotally mounted on the base 11 about a pivot axis 124.

Un premier bras 126 est configuré pour entraîner en rotation la came mono-piste 122, ledit premier bras 126 ayant une extrémité couplée à la came mono-piste 122 par un moyen de couplage rotatif ponctuel 128 distinct de l'axe de pivot 124 et l'autre extrémité couplée à la tuyère 16 solidaire du second connecteur électrique mâle 14 de façon à faire pivoter la came mono-piste 122 par rapport à l'embase 11 autour de l'axe de pivot 124 lors d'un retrait du second connecteur électrique mâle 14 hors du premier connecteur électrique femelle 12 pour réaliser le mode de connexion ouverte, ou inversement, lors de son insertion dans le premier connecteur électrique femelle 12 pour réaliser le mode de connexion fermée.A first arm 126 is configured to rotate the single track cam 122, said first arm 126 having an end coupled to the single track cam 122 by a spot rotating coupling means 128 separate from the pivot axis 124 and other end coupled to the nozzle 16 secured to the second male electrical connector 14 so as to rotate the single-track cam 122 relative to the base 11 about the pivot axis 124 during a withdrawal of the second electrical connector male 14 out of the first female electrical connector 12 to perform the open connection mode, or vice versa, when inserted into the first female electrical connector 12 to achieve the closed connection mode.

Le premier bras 126 est lié à la tuyère 16 via la pièce d'extension 30 fixée à la fin de la partie évasée de la tuyère 16 et s'étendant longitudinalement, le premier bras 126 étant fixé pivotant à la pièce d'extension 30.
un deuxième bras 134 est prévu pour entraîner l'écran mobile 40 :

  • une première extrémité est solidaire de l'écran mobile via la bague 42, comme pour la variante de la Fig.2 ;
  • une deuxième extrémité est entraînée par pivotement de la came 122 au moyen d'un dispositif de couplage par coulissement comprenant un coulisseau 136 solidaire de la deuxième extrémité du deuxième bras 134 et coulissant dans une piste curviligne 138 de la came mono-piste 122.
The first arm 126 is connected to the nozzle 16 via the extension piece 30 attached to the end of the flared portion of the nozzle 16 and extending longitudinally, the first arm 126 being pivotally attached to the extension piece 30.
a second arm 134 is provided to drive the mobile screen 40:
  • a first end is secured to the mobile screen via the ring 42, as for the variant of the Fig.2 ;
  • a second end is driven by pivoting of the cam 122 by means of a sliding coupling device comprising a slider 136 integral with the second end of the second arm 134 and sliding in a curvilinear track 138 of the mono-track cam 122.

Le signe de référence 150 désigne un troisième bras pour l'entrainement du contact d'arc mâle 12'. Le troisième bras 150 est guidé en translation rectiligne selon l'axe A dans l'embase 11. Une première extrémité est munie du contact d'arc mâle. Un couplage mécanique est prévu pour entraîner le troisième bras 150. Un bras pivotant 152 est monté pivotant sur l'embase 11 autour d'un axe 154 fixe par rapport à l'embase 11. Une extrémité comprend une fourche 156 destinée à coopérer avec un ergot 158 faisant saillie sur la pièce d'extension 30 de tuyère. A l'autre extrémité, le bras 156 comprend un axe 160 engagé dans une rainure 162 transversale à l'axe A. Comme on le comprendra, lors du déplacement de la pièce d'extension 30 vers la gauche (mouvement de séparation de la partie mobile DS), l'ergot 158 se déplace vers la gauche, et à partir d'un certain point, entre dans l'espace de la fourche 156 pour faire pivoter le bras pivotant 152 et entraîner le troisième bras 150 dans le sens anti-horaire, de sorte à séparer le contact d'arc mâle 12' du contact d'arc mâle femelle 14'. Bien que le mécanisme d'actionnement 120 soit mû par une force unique transmise par le connecteur mâle permanent 14, l'entraînement de l'écran mobile 40 et du contact d'arc mâle 12' est découplé. Un déplacement coordonné est donc possible, à des vitesses différentes ici.The reference sign 150 designates a third arm for driving the male arc contact 12 '. The third arm 150 is guided in rectilinear translation along the axis A in the base 11. A first end is provided with the male arc contact. Mechanical coupling is provided to drive the third arm 150. A pivoting arm 152 is pivotally mounted on the base 11 about an axis 154 fixed relative to the base 11. One end comprises a fork 156 intended to cooperate with a lug 158 protruding from the nozzle extension piece 30. At the other end, the arm 156 comprises an axis 160 engaged in a groove 162 transverse to the axis A. As will be understood, during the displacement of the extension piece 30 to the left (separation movement of the part mobile DS), the lug 158 moves to the left, and from a certain point enters the space of the fork 156 to pivot the pivoting arm 152 and drive the third arm 150 in the anti-direction. time, so as to separate the male arc contact 12 'of the female male arc contact 14'. Although the actuating mechanism 120 is driven by a single force transmitted by the permanent male connector 14, the driving of the movable screen 40 and the male arc contact 12 'is decoupled. Coordinated displacement is possible at different speeds here.

Les vitesses de déplacement dépendent des choix mécaniques pour les parties d'entrainement. Le bras pivotant 152 à fourche 156 permet un déplacement du contact d'arc mâle 12' à une vitesse plus rapide que celle de l'écran, ce qui permet d'augmenter rapidement la distance entre le bord avant de l'écran 40 et du contact d'arc mâle, et ainsi réduire les contraintes diélectriques à ce niveau pendant la manoeuvre d'ouverture.The speeds of movement depend on the mechanical choices for the training parts. The forked pivot arm 152 permits movement of the male arc contact 12 'at a speed faster than that of the screen, thereby rapidly increasing the distance between the front edge of the screen 40 and the screen. male arc contact, and thus reduce the dielectric stress at this level during the opening maneuver.

En Fig.3A, le disjoncteur est présenté en mode de connexion fermée; le contact principal et le contact d'arc sont établis. Le coulisseau 136 se trouve à une extrémité de la piste curviligne 138 qui est la plus éloignée de l'axe de pivot 24. L'ergot 158 est hors de la fourche 156 du bras pivotant 152.In 3A the circuit breaker is presented in closed connection mode; the main contact and the arc contact are established. The slide 136 is at one end of the curvilinear track 138 which is farthest from the pivot axis 24. The lug 158 is out of the fork 156 of the pivoting arm 152.

La Fig.3B, présente le disjoncteur dans un mode de connexion ouverte (ou connexion fermée) intermédiaire situé entre le mode de connexion fermée et le mode de connexion ouverte, c'est-à-dire lorsque le moment exercé par l'extrémité du premier bras 126 sur la came mono-piste 122 permet à celle-ci de de pivoter sous un couple d'entrainement exercé par la force de traction exercée sur le moyen de couplage rotatif 128, entraînant au même moment le coulisseau 136 en déplacement le long de la piste curviligne 138 de façon à ce que ce dernier se rapproche de l'axe de pivot 124 et en même temps entraine progressivement le contact d'arc mâle 12' pour le sortir du contact d'arc femelle 14' par actionnement du second bras 134.The 3B , presents the circuit breaker in an intermediate open connection mode (or closed connection) located between the closed connection mode and the open connection mode, that is to say when the moment exerted by the end of the first arm 126 on the mono-track cam 122 allows it to pivot under a driving torque exerted by the traction force exerted on the rotary coupling means 128, driving at the same time the slide 136 moving along the curvilinear track 138 so that the latter approaches the pivot axis 124 and at the same time gradually causes the male arc contact 12 'to out of the female arc contact 14' by actuating the second arm 134.

Le disjoncteur est avantageusement configuré de façon à ce que la désolidarisation complète du connecteur principal femelle 12 du connecteur principal mâle 14 se produise avant la désolidarisation complète du contact d'arc mâle 12' du contact d'arc femelle 14', de façon à ce que cette dernière crée une rupture de contact sous arc électrique canalisé par la tuyère 16. Egalement, le coulisseau 136 est configuré pour glisser dans la piste curviligne 138 dont la géométrie curviligne en forme de crochet ou « L » arrondi est adaptée pour minimiser des efforts de frictions du coulisseau avec des bords de ladite piste, et va finalement permettre un faible déplacement relatif du contact d'arc mâle au départ de la position de la Fig.3A.The circuit breaker is advantageously configured so that the complete disconnection of the main female connector 12 of the main male connector 14 occurs before the complete disengagement of the male arc contact 12 'from the female arc contact 14', so that that the latter creates a contact break under electrical arc channeled by the nozzle 16. Also, the slider 136 is configured to slide in the curvilinear track 138 whose curvilinear geometry in the form of hook or "L" rounded is adapted to minimize efforts friction of the slide with edges of said track, and will finally allow a small relative displacement of the male arc contact at the start of the position of the 3A .

La Fig.3C présente le disjoncteur dans une position intermédiaire dans laquelle le disjoncteur est déjà ouvert : le contact d'arc mâle 12' n'est plus en contact avec le contact d'arc femelle 14' et va pénétrer dans la partie conique 161 de la tuyère. La vitesse de déplacement du contact d'arc mâle 12' est nettement supérieure à celle de l'écran grâce au découplage des fonctions d'entrainement. A ce stade, les contacts d'arc sont déjà bien séparés. L'efficacité du bras pivotant 152 permet de ramener rapidement le contact d'arc mâle 12' à l'intérieur du connecteur principal femelle 12.The Fig.3c present the circuit breaker in an intermediate position in which the circuit breaker is already open: the male arc contact 12 'is no longer in contact with the female arc contact 14' and will enter the conical portion 16 1 of the nozzle . The movement speed of the male arc contact 12 'is significantly greater than that of the screen due to the decoupling of the drive functions. At this point, the arcing contacts are already well separated. The effectiveness of the pivoting arm 152 makes it possible to quickly bring back the male arc contact 12 'inside the female main connector 12.

En figure 3D l'écran mobile et le contact d'arc mâle ont atteint leur position finale, le disjoncteur est en position ouverte.In 3D figure the movable screen and the male arc contact have reached their final position, the circuit breaker is in the open position.
