Description

La présente invention concerne un déclencheur pour dispositif de commutation électrique. Le déclencheur comporte un boîtier de protection et des premières bornes de connexion électrique. Le déclencheur comprend en outre un module d'alimentation comportant au moins un transformateur, et des deuxièmes bornes d'entrée et de sortie aptes à être connectées aux premières bornes selon une direction de connexion. Le module d'alimentation est apte à générer une tension d'alimentation à partir d'une tension d'entrée reçue entre les deuxièmes bornes d'entrée, et à délivrer la tension d'alimentation entre les deuxièmes bornes de sortie.The present invention relates to a trigger for an electrical switching device. The release includes a protective housing and first electrical connection terminals. The trigger further comprises a power supply module comprising at least one transformer, and second input and output terminals adapted to be connected to the first terminals in a connection direction. The power supply module is adapted to generate a supply voltage from an input voltage received between the second input terminals, and to deliver the supply voltage between the second output terminals.

La présente invention concerne également un dispositif de commutation électrique, tel qu'un disjoncteur, comprenant un tel déclencheur.The present invention also relates to an electrical switching device, such as a circuit breaker, comprising such a trigger.

On connaît du document EP 0 843 332 A1 un dispositif de commutation d'un courant électrique, le dispositif de commutation comprenant un déclencheur. Le déclencheur est connecté à des capteurs de courant et contrôle la commutation électrique du dispositif en fonction des informations fournies par les capteurs de courant. Ce déclencheur comporte un module d'alimentation dédié, alimenté par la tension à l'entrée du dispositif de commutation, et générant une tension d'alimentation du déclencheur. Un tel module d'alimentation est connu sous le nom d'alimentation à propre tension. Il permet d'alimenter le déclencheur sans raccordement à une alimentation auxiliaire, et fonctionne même lorsque le dispositif de commutation bloque le passage du courant.Document is known EP 0 843 332 A1 a switching device of an electric current, the switching device comprising a trigger. The trip unit is connected to current sensors and controls the electrical switching of the device according to the information provided by the current sensors. This trigger includes a dedicated power supply module, powered by the voltage at the input of the switching device, and generating a supply voltage of the trigger. Such a power module is known as a self-powered power supply. It is used to power the trigger without connection to an auxiliary power supply, and operates even when the switching device blocks the flow of current.

Toutefois, un tel module d'alimentation à propre tension est vulnérable et peut être endommagé dans certaines conditions de fonctionnement. En particulier, lors de certains tests électriques tels que par exemple ceux définis dans la norme IEC 60 947-2 et la norme IEC 61 439-1, le module d'alimentation à propre tension est susceptible d'engendrer un défaut diélectrique. Un défaut de ce type peut alors entraîner la destruction du module d'alimentation à propre tension, et il est dans ce cas généralement nécessaire de procéder au remplacement complet du déclencheur.However, such a self-powered power supply module is vulnerable and can be damaged under certain operating conditions. In particular, during certain electrical tests such as for example those defined in the IEC 60 947-2 standard and the IEC 61 439-1 standard, the power supply module with its own voltage is likely to generate a dielectric fault.

La platine supérieure 48 et les éléments de commande 31 sont mobiles en translation selon la direction de connexion Z par rapport à la coque de protection 21.On the figure 5 , the gripping handle 32 comprises an upper plate 48. The upper plate 48 is integral with each vertical flank 47B, and each vertical flank 47B is for example integral with the upper plate 48. The upper plate 48 and the control elements 31 are movable in translation in the connection direction Z relative to the protective shell 21.

La fente verticale 38 est apte à permettre une translation verticale de la saillie d'arrêt 28 La fente verticale 38 est dimensionnée pour que la saillie d'arrêt 28 vienne au contact de la butée 40 lorsque le module d'alimentation 14 est dans la première position de déconnexion. Dans un mode de réalisation préférentiel, la fente verticale 38 est propre à être recouverte par le capot 10 quand il est fixé au bloc disjoncteur 4.The vertical slot 38 is able to allow a vertical translation of the stop projection 28 The vertical slot 38 is dimensioned so that the stop projection 28 comes into contact with the stop 40 when the feed module 14 is in the first disconnect position. In a preferred embodiment, the vertical slot 38 is adapted to be covered by the cover 10 when it is fixed to the circuit breaker block 4.

La butée 40 est située à l'extrémité supérieure de la fente verticale 38.The stop 40 is located at the upper end of the vertical slot 38.

Sur la figure 6, la saillie de verrouillage 44 comporte un pan incliné 52 apte à faciliter le mouvement du module d'alimentation 14 depuis l'une des positions de déconnexion vers la position de connexion.On the figure 6 , the locking projection 44 has an inclined portion 52 adapted to facilitate the movement of the supply module 14 from one of the disconnection positions to the connection position.

La saillie de verrouillage 44 est apte à empêcher le mouvement du module d'alimentation 14 hors de la position de connexion quand les moyens de verrouillage 18 sont en position de verrouillage. Sur la figure 6, la saillie de verrouillage 44 comporte une surface de blocage 54 apte à coopérer avec l'organe de blocage 37. La surface de blocage 54 est de préférence sensiblement perpendiculaire à la direction de connexion Z.The locking projection 44 is able to prevent the movement of the supply module 14 out of the connection position when the locking means 18 are in the locking position. On the figure 6 , the locking projection 44 has a locking surface 54 adapted to cooperate with the locking member 37. The locking surface 54 is preferably substantially perpendicular to the connection direction Z.

Les moyens complémentaires de commande 46 comportent, pour chaque portion flexible 42, une surface de came 56 apte à coopérer avec un ergot d'actionnement 47A correspondant pour déplacer la saillie de verrouillage 44 correspondante vers l'intérieur du module d'alimentation 14, c'est-à-dire pour faire passer les moyens de verrouillage 18 de leur position de verrouillage à leur position de déverrouillage. La surface de came 56 forme un angle strictement compris entre 0° et 90° avec la face latérale 41 A de la coque, c'est-à-dire avec la direction verticale Z, l'angle étant de préférence compris entre 10 et 50°.The additional control means 46 comprise, for each flexible portion 42, a cam surface 56 adapted to cooperate with an actuating pin 47A corresponding to move the corresponding locking projection 44 towards the inside of the feed module 14, c that is to say for passing the locking means 18 from their locking position to their unlocking position. The cam surface 56 forms an angle strictly between 0 ° and 90 ° with the lateral face 41 A of the shell, that is to say with the vertical direction Z, the angle preferably being between 10 and 50 °.

Les moyens complémentaires de commande 46 comportent, pour chaque portion flexible 42, une surface 58 de stabilisation de la saillie de verrouillage 44 à l'écart de l'organe de blocage 37 correspondant. Chaque surface de stabilisation 58 est configurée pour maintenir les moyens de verrouillage 18 dans leur position de déverrouillage, après la saisie par un opérateur de la poignée de préhension 32. Chaque surface de stabilisation 58 est sensiblement parallèle à la face latérale 41 A de la coque, c'est-à-dire à la direction verticale Z. Chaque surface de stabilisation 58 est susceptible d'effectuer une rotation de quelques degrés autour d'une direction perpendiculaire à la direction verticale Z, lors du passage des moyens de verrouillage 18 de leur position de verrouillage à leur position de déverrouillage.The additional control means 46 comprise, for each flexible portion 42, a surface 58 for stabilizing the locking projection 44 away from the corresponding locking member 37. Each stabilizing surface 58 is configured to hold the locking means 18 in their unlocking position, after an operator grasps the gripping handle 32. Each stabilizing surface 58 is substantially parallel to the lateral face 41 A of the shell , that is to say to the vertical direction Z. Each stabilizing surface 58 is capable of rotating a few degrees around a direction perpendicular to the vertical direction Z, during the passage of the locking means 18 of their locking position to their unlocking position.

La portion flexible 42 est par exemple venue de matière avec la coque de protection 21. La portion flexible 42 est apte à se déformer vers l'intérieur de la coque de protection 21 sous l'action d'une force F, visible à la figure 6.The flexible portion 42 is for example integral with the protective shell 21. The flexible portion 42 is adapted to deform inwardly of the protective shell 21 under the action of a force F, visible to the figure 6 .

Dans l'exemple de réalisation des figures 1 à 8, le module mobile, de préférence en translation, par rapport au boitier de protection 12 est le module d'alimentation 14. L'homme du métier comprendra alors que l'invention s'applique plus généralement à tout module du déclencheur 6, et que les moyens 17 de maintien dans au moins une position de déconnexion sont, en variante ou en complément, associés à tout type de module inclus dans le déclencheur 6. De manière analogue, les moyens d'arrêt 19 et/ou les moyens de verrouillage 18 sont, en variante ou en complément, associés à tout type de module qui est inclus dans le déclencheur 6 et est mobile par rapport au boitier de protection 12.In the exemplary embodiment of Figures 1 to 8 , the mobile module, preferably in translation, relative to the protective housing 12 is the power supply module 14. Those skilled in the art will understand that the invention applies more generally to any module of the trigger 6, and that the means 17 for holding in at least one disconnection position are, alternatively or in addition, associated with any type of module included in the trigger 6. Similarly, the stop means 19 and / or the locking means 18 are, alternatively or in addition, associated with any type of module that is included in the trigger 6 and is movable relative to the protective housing 12.

Ainsi, le module d'alimentation 14 est mobile en translation par rapport au boîtier de protection 12 du déclencheur selon une direction de connexion. Le module d'alimentation 14 est mobile entre une position de connexion et une première position de déconnexion. Les moyens de verrouillage 18 sont, par défaut, i.e. lorsque la poignée de préhension 32 n'est pas manipulée, aptes à bloquer le module d'alimentation 14 dans la position de connexion. Autrement dit, lorsque le module d'alimentation 14 est en position de connexion et que les moyens de verrouillage 18 sont en position de verrouillage, les moyens de verrouillage 18 empêchent le mouvement du module d'alimentation 14 hors de la position de verrouillage tant que la poignée de préhension 32 n'est pas manipulée.Thus, the power module 14 is movable in translation relative to the protective housing 12 of the trigger in a connection direction. The power supply module 14 is movable between a connection position and a first disconnection position. The locking means 18 are, by default, i.e. when the handle 32 is not manipulated, able to block the supply module 14 in the connection position. In other words, when the supply module 14 is in the connection position and the locking means 18 are in the locking position, the locking means 18 prevent the movement of the supply module 14 out of the locking position as long as the handle 32 is not manipulated.

L'élasticité de la portion flexible 42 assure un maintien des moyens de verrouillage 18 dans leur position de verrouillage en l'absence d'action sur la poignée de préhension 32.The elasticity of the flexible portion 42 maintains the locking means 18 in their locking position in the absence of action on the handle 32.

Le mouvement des moyens de verrouillage 18 de leur position de verrouillage à leur position de déverrouillage est obtenu par action sur la poignée de préhension 32. Le mouvement en translation de la poignée de préhension 32 par rapport à la coque 21 entraîne le mouvement des ergots d'actionnement 47A selon la direction de connexion. De par la surface de came 56, les ergots d'actionnement 47A entraînent la rotation de la portion flexible 42 des moyens de verrouillage 18, notamment des saillies de verrouillage 44, vers l'intérieur de la coque 21. Les moyens de verrouillage 18 passent alors dans leur position de déverrouillage, et la poursuite du mouvement de traction vers le haut de la poignée de préhension 32 provoque alors une extraction au moins partielle du module d'alimentation 14 par rapport au boitier de protection 12, c'est-à-dire un mouvement du module d'alimentation 14 depuis sa position de connexion vers l'une de ses positions de déconnexion en exerçant sur la poignée de préhension 32 une force de traction T dans la direction de connexion Z visible sur les figures 2 et 3.The movement of the locking means 18 from their locking position to their unlocking position is obtained by action on the gripping handle 32. The translational movement of the gripping handle 32 relative to the shell 21 causes the movement of the lugs 47A actuation according to the connection direction. Through the cam surface 56, the actuating pins 47A rotate the flexible portion 42 of the locking means 18, in particular the locking projections 44, towards the inside of the shell 21. The locking means 18 pass through. then in their unlocking position, and the continuation of the upward movement of the gripping handle 32 then causes at least partial extraction of the supply module 14 relative to the protective housing 12, that is to say say a movement of the supply module 14 from its connection position to one of its disconnection positions by exerting on the handle 32 a tensile force T in the direction of connection Z visible on the figures 2 and 3 .

Le mouvement du module d'alimentation 14 par rapport au boîtier 12 et le mouvement de la poignée de préhension 32 par rapport à la coque 21 sont des mouvements de translation selon la direction de connexion Z.The movement of the supply module 14 relative to the housing 12 and the movement of the handle 32 relative to the shell 21 are translational movements in the connection direction Z.

Une traction sur la poignée de préhension 32 permet alors d'obtenir à la fois le déverrouillage du module d'alimentation 14 et le mouvement du module d'alimentation 14 hors de la position de connexion. De plus, le choix d'un tel mouvement de translation du module d'alimentation 14 par rapport au boîtier 12 permet l'utilisation de moyens de maintien 17 simples, tels que des moyens élastiques de maintien, par exemple des moyens de maintien par encliquetage, ou encore des moyens magnétiques de maintien.Pulling on the gripping handle 32 then makes it possible to obtain both the unlocking of the feed module 14 and the movement of the feed module 14 out of the connection position. In addition, the choice of such a translational movement of the supply module 14 with respect to the housing 12 allows the use of 17 simple maintenance, such as elastic holding means, for example snap-fastening means, or magnetic holding means.

Dans l'exemple de la figure 7, le maintien du module d'alimentation 14 dans la première position de déconnexion est obtenu grâce à l'encliquetage des saillies de maintien 24 dans la première ouverture 34. Autrement dit, la coopération des saillies de maintien 24 par encliquetage avec la première ouverture 34 assure une force de maintien supérieure au poids du module d'alimentation 14 et s'opposant audit poids du module d'alimentation 14 selon la direction verticale Z.In the example of the figure 7 , the maintenance of the supply module 14 in the first disconnected position is obtained by latching the retaining projections 24 into the first opening 34. In other words, the cooperation of the retaining projections 24 snap with the first opening 34 provides a holding force greater than the weight of the feed module 14 and opposing said weight of the feed module 14 in the vertical direction Z.

La flexibilité de la languette élastique 30 permet sa déformation vers l'intérieur de la coque 21 lors de l'exercice d'une force supérieure à la force de maintien. L'application selon la direction de connexion d'une force supérieure à la force de maintien, elle-même supérieure au poids du module d'alimentation 14, entraîne alors le mouvement du module d'alimentation 14 de la première position de déconnexion vers la position de connexion.The flexibility of the elastic tongue 30 allows its deformation inwardly of the shell 21 when exerting a force greater than the holding force. The application in the direction of connection of a force greater than the holding force, itself greater than the weight of the power supply module 14, then causes the movement of the power supply module 14 from the first disconnection position to the connection position.

Selon la figure 8, lorsque le module d'alimentation 14 est en position de connexion, les saillies de maintien 24 sont encliquetées dans l'ouverture basse 36, et la languette 30 est alors dans sa position de repos. L'encliquetage des saillies de maintien 24 dans l'ouverture basse 36 permet une position de la saillie d'arrêt 28 à l'écart de la paroi latérale 33B, et de limiter ainsi une déformation de la languette 30 dans cette position. La flexibilité de la languette élastique 30 permet la déformation de la languette 30 vers l'intérieur de la coque 21 sous l'action d'une force supérieure au poids du module. En conséquence, si un opérateur exerce une force supérieure au poids du module d'alimentation 14 dans la direction de connexion, l'opérateur peut forcer le mouvement du module d'alimentation 14 de la position de connexion à la première position de déconnexion lorsque les moyens de verrouillage 18 sont dans leur position de déverrouillage.According to figure 8 when the supply module 14 is in the connection position, the retaining projections 24 are snapped into the lower opening 36, and the tongue 30 is then in its rest position. The latching of the holding protrusions 24 in the lower opening 36 allows a position of the stop projection 28 away from the side wall 33B, and thus to limit deformation of the tongue 30 in this position. The flexibility of the elastic tongue 30 allows the deformation of the tongue 30 towards the inside of the shell 21 under the action of a force greater than the weight of the module. Accordingly, if an operator exerts a force greater than the weight of the feed module 14 in the direction of connection, the operator can force the movement of the feed module 14 from the connection position to the first disconnect position when the locking means 18 are in their unlocking position.

Lorsque le module d'alimentation 14 est dans la première position de déconnexion, la saillie d'arrêt 28 est en appui contre la butée 40 de la fente verticale 38. La saillie d'arrêt 28 empêche donc le mouvement du module d'alimentation 14 vers l'extérieur du boîtier 12. La flexibilité de la languette 30 permet néanmoins à un opérateur de forcer le mouvement de la languette 30 vers l'intérieur de la coque 21, par exemple à l'aide d'un outil, tel qu'un tournevis, aux fins de l'extraction totale du module d'alimentation 14 par rapport au boîtier 12. L'opérateur désengage alors la saillie d'arrêt 28 par rapport à la butée 40.When the supply module 14 is in the first disconnection position, the stop projection 28 bears against the stop 40 of the vertical slot 38. The stop projection 28 thus prevents the movement of the supply module 14 The flexibility of the tongue 30 nevertheless allows an operator to force the movement of the tongue 30 towards the inside of the shell 21, for example by means of a tool such as a screwdriver, for the purpose of the total extraction of the supply module 14 relative to the housing 12. The operator then disengages the stop projection 28 relative to the stop 40.

Selon un mode de réalisation préférentiel, le capot 10 recouvre entièrement la fente 38 lorsqu'il est fixé au bloc disjoncteur 4. Il est alors nécessaire de démonter le capot 10 pour pouvoir désengager la saillie d'arrêt 28 de la butée 40, et donc pour pouvoir extraire totalement le module d'alimentation 14 par rapport au boîtier 12.According to a preferred embodiment, the cover 10 completely covers the slot 38 when it is fixed to the circuit breaker block 4. It is then necessary to disassemble the cover 10 to be able to disengage the stop projection 28 of the stop 40, and thus to be able to completely extract the supply module 14 with respect to the housing 12.

Dans l'exemple de la figure 1, le capot 10 comporte une ouverture en regard de la poignée de préhension 32, et ne recouvre alors pas la poignée de préhension 32 lorsqu'il est fixé au bloc disjoncteur 4. Le capot 10 permet donc à un opérateur d'agir directement sur la poignée de préhension 32, sans avoir à retirer le capot 10, pour déplacer le module d'alimentation 14 entre sa position de connexion et sa première position de déconnexion. L'opérateur peut ainsi facilement déconnecter électriquement le module d'alimentation 14, par exemple pour effectuer des tests, sans pour autant démonter le capot 10.In the example of the figure 1 , the cover 10 has an opening facing the grip 32, and then does not cover the handle 32 when attached to the circuit breaker block 4. The cover 10 allows an operator to act directly on the gripping handle 32, without having to remove the cover 10, to move the supply module 14 between its connection position and its first disconnected position. The operator can thus easily electrically disconnect the power supply module 14, for example to carry out tests without disassembling the cover 10.

Le mouvement de translation permet une déconnexion aisée du module d'alimentation 14 par un mouvement simple pour l'opérateur. De plus, le choix d'un mouvement de translation permet de minimiser le volume du logement 16 de réception du module d'alimentation 14. Enfin, un opérateur peut aisément vérifier la déconnexion du module d'alimentation 14 par une simple vérification visuelle de la position du module.The translation movement allows easy disconnection of the power supply module 14 by a simple movement for the operator. In addition, the choice of a translational movement makes it possible to minimize the volume of the receiving housing 16 of the supply module 14. Finally, an operator can easily check the disconnection of the supply module 14 by a simple visual verification of the module position.

Un tel dispositif de commutation 2 permet donc une déconnexion aisée du module d'alimentation 14, puis son maintien dans la première position de déconnexion. La première position de déconnexion correspond en outre à une extraction seulement partielle du module d'alimentation 14 par rapport au boîtier 12, ce qui évite de perdre ou de détériorer le module d'alimentation 14 lors des tests. Un tel dispositif de commutation 2 facilite donc la réalisation de tests électriques nécessitant la déconnexion du module d'alimentation 14.Such a switching device 2 thus allows easy disconnection of the power supply module 14, then its maintenance in the first disconnection position. The first disconnection position also corresponds to a only partial extraction of the power supply module 14 with respect to the housing 12, which avoids losing or deteriorating the power supply module 14 during the tests. Such a switching device 2 thus facilitates the performance of electrical tests requiring the disconnection of the power supply module 14.

De plus, le dispositif de commutation 2 selon l'invention empêche l'extraction du module d'alimentation 14 si le capot 10 n'est pas démonté. Ainsi, le dispositif de commutation 2 est sécurisé en ce qu'il permet l'extraction du module d'alimentation 14 seulement par les opérateurs habilités à démonter le capot 10.In addition, the switching device 2 according to the invention prevents the extraction of the power supply module 14 if the cover 10 is not removed. Thus, the switching device 2 is secure in that it allows the extraction of the power supply module 14 only by the operators authorized to disassemble the cover 10.

En variante, la languette 30 est portée par une paroi latérale du logement 16. Le boîtier 12 comporte alors un élément de traction (non représenté) apte à forcer la déformation de la languette 30 vers l'extérieur du boîtier 12. La première ouverture 34, la deuxième ouverture 36 et la fente 38 sont alors portées par le module d'alimentation 14. Le reste du dispositif de commutation 2 est inchangé.Alternatively, the tongue 30 is carried by a side wall of the housing 16. The housing 12 then comprises a traction element (not shown) capable of forcing the deformation of the tongue 30 towards the outside of the housing 12. The first opening 34 the second opening 36 and the slot 38 are then carried by the supply module 14. The rest of the switching device 2 is unchanged.

Selon cette variante, l'extraction du module d'alimentation 14 hors du boîtier 12 est permise via l'application par l'opérateur sur l'élément de traction d'une force dirigée vers l'extérieur du boîtier 12. Cette force permet de désengager la saillie d'arrêt 28 de la butée 40. Cette variante de réalisation présente l'avantage de ne pas nécessiter l'utilisation d'un outil additionnel, tel qu'un tournevis, pour permettre l'extraction du module d'alimentation 14. De plus, il n'est pas nécessaire de prévoir dans le module d'alimentation 14 un volume permettant la déformation de la languette 30.According to this variant, the extraction of the supply module 14 from the housing 12 is allowed via the application by the operator on the traction element of a force directed towards the exterior of the housing 12. This force makes it possible to disengage the stop projection 28 of the stop 40. This variant embodiment has the advantage of not requiring the use of an additional tool, such as a screwdriver, to allow the extraction of the power supply module. 14. In addition, it is not necessary to provide in the supply module 14 a volume allowing the deformation of the tongue 30.

On conçoit ainsi que le déclencheur 6 selon l'invention permet une déconnexion électrique aisée du module d'alimentation 14 et sa mise en sécurité pendant la réalisation de tests électriques.It is thus conceivable that the trigger 6 according to the invention allows easy electrical disconnection of the power supply module 14 and its safety during the performance of electrical tests.
