Description

La présente invention concerne un disjoncteur électrique incluant un bloc déclencheur.The present invention relates to an electric circuit breaker including a trigger block.

Dans le domaine des disjoncteurs électriques, il est connu, par exemple de EP-A-0 843 332 , de prévoir deux ou plusieurs blocs indépendants dans un disjoncteur. Dans ce document, un disjoncteur électrique est équipé d'un bloc disjoncteur, lequel inclut des pastilles fixe et mobile et une unité de commande de la position de la pastille mobile, et d'un bloc déclencheur. Il est possible d'utiliser un disjoncteur avec différents types de bloc déclencheur : par exemple un bloc déclencheur thermique, magnétique, différentiel ou électronique. Un bloc déclencheur électronique permet de réaliser, à la fois, les fonctions du bloc déclencheur thermique et du bloc déclencheur magnétique grâce au traitement électronique des mesures effectuées. Un tel bloc déclencheur électronique a une durée de vie inférieure à celle du bloc disjoncteur. Il est donc généralement amovible et n'est monté dans le disjoncteur que lors de l'installation de celui-ci. Le disjoncteur électrique ne peut accomplir sa fonction de protection que si le bloc déclencheur est correctement connecté au bloc disjoncteur. Toutefois, cette approche n'empêche pas la fermeture du bloc disjoncteur lorsque le bloc déclencheur est absent ou n'est pas correctement connecté.In the field of electric circuit breakers, it is known, for example EP-A-0 843 332 , to provide two or more independent blocks in a circuit breaker. In this document, an electric circuit breaker is equipped with a circuit breaker block, which includes fixed and movable pads and a control unit of the position of the mobile chip, and a trigger block. It is possible to use a circuit breaker with different types of trip unit: for example a thermal, magnetic, differential or electronic trip unit. An electronic trigger block is used to perform both the functions of the thermal trip unit and the magnetic trip unit by electronically processing the measurements made. Such an electronic trip unit has a life shorter than that of the circuit breaker block. It is generally removable and is mounted in the circuit breaker when installing it. The circuit breaker can only perform its protection function if the trip unit is properly connected to the circuit breaker block. However, this approach does not prevent the breaker block from closing when the trigger block is missing or not properly connected.

C'est à cet inconvénient qu'entend plus particulièrement remédier l'invention en proposant un disjoncteur électrique plus sûr.It is this disadvantage that the invention intends to remedy more particularly by proposing a safer electric circuit breaker.

Dans cet esprit, l'invention concerne un disjoncteur électrique comprenant un bloc disjoncteur, lequel inclut au moins un conducteur électrique équipé d'une première pastille fixe. Le bloc disjoncteur inclut également un pont équipé d'au moins une deuxième pastille, le pont étant mobile entre une première position où la deuxième pastille est en contact avec la première pastille et une deuxième position où la deuxième pastille est écartée de la première pastille. Le bloc disjoncteur inclut également une unité de commande du pont mobile et un actionneur de l'unité de commande. Cet actionneur est apte à passer entre une configuration armée où il active l'unité de commande et une configuration désarmée où il n'active pas l'unité de commande. De plus, le bloc disjoncteur inclut un premier module de couplage électrique. Le disjoncteur électrique comprend également un bloc déclencheur, lequel bloc inclut un circuit de déclenchement électronique et un deuxième module de couplage électrique avec le premier module de couplage du bloc disjoncteur. Conformément à l'invention, le bloc déclencheur est pourvu d'un verrou d'armement de l'actionneur. De plus, ce verrou est chargé élastiquement vers une première position où l'actionneur est en configuration désarmée et est adapté pour être repoussé vers une deuxième position où l'actionneur est en configuration armée lorsque le premier et le deuxième module de couplage sont connectés électriquement.In this spirit, the invention relates to an electric circuit breaker comprising a circuit breaker block, which includes at least one electrical conductor equipped with a first fixed patch. The breaker block also includes a bridge equipped with at least a second wafer, the bridge being movable between a first position where the second wafer is in contact with the first wafer and a second position where the second wafer is removed from the first wafer. The circuit breaker block also includes a mobile bridge control unit and an actuator of the control unit. This actuator is able to pass between an armed configuration where it activates the control unit and a disarmed configuration where it does not activate the control unit. In addition, the circuit breaker unit includes a first electrical coupling module. The electrical circuit breaker also includes a trip unit, which block includes an electronic trip circuit and a second electrical coupling module with the first circuit breaker block coupling module. According to the invention, the trigger block is provided with a cocking latch of the actuator. Moreover, this lock is elastically loaded towards a first position where the actuator is in the disarmed configuration and is adapted to be pushed back to a second position where the actuator is in the armed configuration when the first and the second coupling module are electrically connected.

Grâce à l'invention, un système mécanique fiable et simple est développé pour garantir la protection des biens et des personnes. Le système mécanique résultant est simple, puisque l'élément de mise en oeuvre de l'invention, c'est-à-dire le verrou en tant que tel, est très connu, facilement utilisable et à bas coût. Ce système est également fiable, puisque la commande de fermeture des pastilles ne survient que si les deux mécanismes de contrôle, c'est-à-dire le verrou et l'actionneur, se trouvent en même temps dans la configuration armée pour l'actionneur et la position d'armement pour le verrou. La fermeture du bloc disjoncteur sans analyse par le bloc déclencheur est ainsi empêchée.Thanks to the invention, a reliable and simple mechanical system is developed to ensure the protection of property and people. The resulting mechanical system is simple, since the implementation element of the invention, that is to say the lock as such, is well known, easily used and low cost. This system is also reliable, since the closing order of the pellets only occurs if the two control mechanisms, ie the latch and the actuator, are at the same time in the armed configuration for the actuator and the arming position for the lock. Closing the circuit breaker block without analysis by the trigger block is thus prevented.

Selon des aspects avantageux mais non obligatoires de l'invention, un tel disjoncteur électrique comprend une ou plusieurs des caractéristiques suivantes, prises selon toute combinaison techniquement admissible :

  • Le verrou d'armement est mobile en translation entre sa première position et sa deuxième position.
  • Le bloc déclencheur est pourvu d'une niche de réception de l'actionneur, la niche recevant l'actionneur lorsque le verrou d'armement est dans sa première position.
  • Le verrou d'armement obture la niche de réception lorsqu'il est dans sa deuxième position et empêche l'actionneur de s'y loger.
  • Le verrou d'armement est pourvu d'une patte, la patte étant sur la trajectoire de connexion lorsque le verrou est dans sa première position.
  • La patte est mise en appui contre une butée du bloc déclencheur lorsque le verrou est dans sa position d'armement.
  • Lors de la connexion électrique entre les premier et deuxième modules de couplage, le verrou est déplacé manuellement vers sa deuxième position.
  • Le bloc déclencheur est pourvu d'un ressort de torsion pour charger élastiquement le verrou d'armement.
  • Le module de couplage du bloc disjoncteur est porté de manière déplaçable par le bloc disjoncteur.
According to advantageous but non-mandatory aspects of the invention, such an electric circuit breaker comprises one or more of the following characteristics, taken in any technically permissible combination:
  • The cocking lock is pivotable between its first position and its second position about an axis of rotation parallel to a connection path of the first and second coupling modules,
  • The cocking lock is movable in translation between its first position and its second position.
  • The trigger block is provided with a receiving niche of the actuator, the niche receiving the actuator when the cocking lock is in its first position.
  • The arming lock closes the receiving niche when it is in its second position and prevents the actuator from lodging there.
  • The arming lock is provided with a tab, the tab being on the connection path when the lock is in its first position.
  • The tab is placed against a stop of the trigger block when the lock is in its arming position.
  • During the electrical connection between the first and second coupling modules, the latch is moved manually to its second position.
  • The trigger block is provided with a torsion spring for resiliently loading the cocking lock.
  • The coupling module of the circuit breaker block is movably carried by the circuit breaker block.

Des moyens de connexion 56 réalisent une liaison mécanique entre un actionneur 52 et l'unité de commande 50. Dans l'exemple considéré ici, l'actionneur 52 est un levier d'actionnement. On note X52 un axe perpendiculaire au plan de la figure 1. Le levier d'actionnement 52 est mobile en rotation autour de l'axe X52 et est apte à passer entre une configuration, dite armée, qui est montré sur les figures 4 et 5, où le levier 52 active mécaniquement l'unité de commande 50 et une configuration, dite désarmée, qui est montrée sur les figures 2 et 3, où le levier 52 n'active pas l'unité de commande 50. Un ressort 54, notamment un ressort à compression, solidarisé à la surface 40 du bloc disjoncteur 4, charge mécaniquement le levier 52 vers sa configuration désarmée. Le ressort 54 exerce ainsi un effort E54 qui tend à déplacer le levier 52 vers sa configuration désarmée.Connection means 56 provide a mechanical connection between an actuator 52 and the control unit 50. In the example considered here, the actuator 52 is an actuating lever. X52 is an axis perpendicular to the plane of the figure 1 . The actuating lever 52 is rotatable about the axis X52 and is able to pass between a configuration, called army, which is shown on the Figures 4 and 5 , where the lever 52 mechanically activates the control unit 50 and a configuration, said disarmed, which is shown on the Figures 2 and 3 , where the lever 52 does not activate the control unit 50. A spring 54, in particular a compression spring, secured to the surface 40 of the circuit breaker block 4, mechanically loads the lever 52 towards its disarmed configuration. The spring 54 thus exerts a force E54 which tends to move the lever 52 to its disarmed configuration.

Le bloc disjoncteur 4 est également équipé d'un module de couplage électrique 58, lequel module 58 est connecté au bloc 4 via un conducteur électrique souple 59. En d'autres termes, le conducteur 59 permet de relier électriquement le module 58 au bloc disjoncteur 4, tout en gardant une mobilité du module 58 par rapport à celui-ci.The circuit breaker block 4 is also equipped with an electrical coupling module 58, which module 58 is connected to the block 4 via a flexible electrical conductor 59. In other words, the conductor 59 makes it possible to electrically connect the module 58 to the circuit breaker block. 4, while keeping a mobility of the module 58 relative thereto.

Le bloc disjoncteur 4 comporte enfin sur sa surface 40 un alésage taraudé 45.The circuit breaker unit 4 finally has on its surface 40 a tapped bore 45.

Le bloc déclencheur 6 est pourvu d'une surface 60 et d'un alésage lisse 61 ménagé sur sa surface 60.The trigger block 6 is provided with a surface 60 and a smooth bore 61 formed on its surface 60.

Le bloc déclencheur 6 est équipé d'un circuit de déclenchement électronique, lequel circuit est omis sur les figures 1 à 5 pour une meilleure clarté des dessins. De manière connue en soi, le circuit de déclenchement électronique à la fonction de mesurer le courant électrique qui passe entre les plages entrant 41 et sortant 42 du disjoncteur 2 et de le comparer à une valeur définie. Le circuit est configuré pour commander l'ouverture ou non des pastilles 44 et 48 en fonction du résultat de la comparaison précitée.The trigger block 6 is equipped with an electronic trip circuit, which circuit is omitted on the Figures 1 to 5 for better clarity of the drawings. In a manner known per se, the electronic triggering circuit has the function of measuring the electric current that passes between the incoming and outgoing ranges 42 of the circuit breaker 2 and comparing it to a defined value. The circuit is configured to control the opening or not of the pellets 44 and 48 according to the result of the aforementioned comparison.

Le bloc déclencheur 6 est équipé également d'un module de couplage électrique 64, ce module 64 étant en connexion électrique avec le circuit de déclenchement. De plus, le module 64 est destiné à se connecter électriquement au module de couplage 58 du bloc disjoncteur 4. On note T une trajectoire de connexion des modules de couplage 58 et 64.The triggering unit 6 is also equipped with an electrical coupling module 64, this module 64 being in electrical connection with the tripping circuit. In addition, the module 64 is intended to connect electrically to the coupling module 58 of the circuit breaker block 4. Note T a connection path of the coupling modules 58 and 64.

Le bloc déclencheur 6 est équipé également d'une niche 66 ménagée sur la surface 60 du bloc 6.The trigger unit 6 is also equipped with a recess 66 formed on the surface 60 of the block 6.

Un verrou d'armement 68 est monté sur la surface 60 du bloc déclencheur 6. On note 680 un corps du verrou 68 délimité entre deux surfaces 68A et 68B perpendiculaires à la trajectoire T. On note P68 un plan perpendiculaire à la trajectoire T et passant au milieu du corps 680. Le corps 680 du verrou 68 a une section globalement en forme de rectangle suivant le plan P68. Le verrou d'armement 68 est pourvu d'une patte 72 en saillie perpendiculairement au corps 680 et parallèlement au plan P68.An arming lock 68 is mounted on the surface 60 of the triggering unit 6. A lock body 68 delimited between two surfaces 68A and 68B perpendicular to the trajectory T is denoted 680. A plane perpendicular to the trajectory T and passing through P is denoted P68. in the middle of the body 680. The body 680 of the latch 68 has a generally rectangular-shaped section along the plane P68. The cocking lock 68 is provided with a tab 72 projecting perpendicular to the body 680 and parallel to the plane P68.

A une extrémité du corps 680, le verrou 68 est solidaire d'un ressort 70, tel qu'un ressort à torsion, qui est lui-même solidaire de la surface 60 du bloc déclencheur 6. On note X70 un axe de torsion du ressort 70. L'axe X70 est perpendiculaire au plan P68 du corps 680 du verrou 68. Le verrou d'armement 68 est pivotant autour de l'axe X70 entre une première position, qui est montrée sur les figures 2 et 3 et où le levier d'actionnement 52 est en configuration désarmée, et une deuxième position, qui est montrée sur les figures 4 et 5 et où le levier 52 est en configuration armée. La première position est dite de désarmement du levier 52 : dans cette position du verrou 68, la patte 72 est agencée sur la trajectoire T. La deuxième position est dite d'armement du levier 52 : la patte est en dehors de la trajectoire T. Le ressort de torsion 70 charge élastiquement le verrou d'armement 68 vers sa première position. Le ressort à torsion 70 exerce ainsi un effort E70 qui tend à pousser le verrou 68 vers sa position de désarmement et, de ce fait, à placer la patte 72 sur la trajectoire de connexion T.At one end of the body 680, the lock 68 is integral with a spring 70, such as a torsion spring, which is itself secured to the surface 60 of the trigger block 6. X70 is a torsion axis of the spring 70. The axis X70 is perpendicular to the plane P68 of the body 680 of the bolt 68. The cocking bolt 68 is pivotable about the axis X70 between a first position, which is shown on the Figures 2 and 3 and where the actuating lever 52 is in the disarmed configuration, and a second position, which is shown on the Figures 4 and 5 and where the lever 52 is in armed configuration. The first position is said disarming lever 52: in this position of the lock 68, the tab 72 is arranged on the path T. The second position is said arming lever 52: the tab is outside the path T. The torsion spring 70 resiliently loads the cocking lock 68 to its first position. The torsion spring 70 thus exerts a force E70 that tends to push the latch 68 towards its disarming position and, thus, to place the tab 72 on the connection path T.

A titre de sécurité, une butée 74 est ménagée sur la surface 60 du bloc déclencheur 6, en étant en saillie perpendiculairement à cette surface. Lorsque le verrou 68 est dans sa deuxième position, la patte 72 est en appui de la butée 74. En d'autres termes, la butée 74 est configurée pour arrêter le verrou 68 dans sa course de rotation et éviter, par exemple, un endommagement du ressort 70.For safety, a stop 74 is provided on the surface 60 of the trigger block 6, projecting perpendicularly to this surface. When the latch 68 is in its second position, the tab 72 is in abutment with the stop 74. In other words, the stop 74 is configured to stop the latch 68 in its rotational stroke and avoid, for example, damage of the spring 70.

Le bloc déclencheur 6 est configuré pour être monté sur le bloc disjoncteur 4, de manière que la surface 60 du bloc déclencheur 6 soit en appui contre la surface 40 du bloc disjoncteur 4. De plus, en configuration montée, l'alésage taraudé 45 du bloc disjoncteur 4 est aligné avec l'alésage lisse 61 du bloc déclencheur 6. Une vis 22 est alors prévue pour bloquer l'assemblage entre le bloc 4 et le bloc 6.The trigger block 6 is configured to be mounted on the circuit breaker block 4, so that the surface 60 of the trigger block 6 bears against the surface 40 of the circuit breaker block 4. In addition, in the mounted configuration, the threaded bore 45 of the The circuit breaker block 4 is aligned with the smooth bore 61 of the trigger block 6. A screw 22 is then provided to block the connection between the block 4 and the block 6.

Dans la configuration montée telle que montrée à la figure 2, le levier d'actionnement 52 se trouve dans sa position désarmée et est logé dans la niche 66 du bloc déclencheur 6. Le module de couplage 58 du bloc disjoncteur 4 n'est pas connecté électriquement au module de couplage 64 du bloc déclencheur 6. De plus, le ressort de torsion 70 tient le verrou d'armement 68 dans sa position de désarmement. Puisque le verrou 68 est dans sa position de désarmement, la patte 72 se trouve sur la trajectoire de connexion T des modules de couplage 58 et 64. Par voie de conséquence, la patte 72 du verrou 68 empêche la connexion électrique entre les modules de couplage 58 et 64.In the assembled configuration as shown in figure 2 , the actuating lever 52 is in its disarmed position and is housed in the niche 66 of the triggering unit 6. The coupling module 58 of the circuit breaker block 4 is not electrically connected to the coupling module 64 of the triggering unit 6. In addition, the torsion spring 70 holds the cocking lock 68 in its disarming position. Since the latch 68 is in its disarming position, the tab 72 is on the connection path T of the coupling modules 58 and 64. As a result, the tab 72 of the latch 68 prevents the electrical connection between the coupling modules. 58 and 64.

Le levier d'actionnement 52 étant dans sa position désarmée, l'unité de commande 50 maintient le pont 46 dans sa deuxième position où la pastille mobile 48 est écartée de la pastille fixe 44. Aucun courant ne peut donc passer entre la plage de courant entrant 41 et la plage de courant sortant 42. Le disjoncteur électrique 2 est ainsi dans sa configuration ouverte.The actuating lever 52 being in its disarmed position, the control unit 50 holds the bridge 46 in its second position where the mobile pellet 48 is spaced from the fixed pellet 44. No current can therefore pass between the current range. incoming 41 and the outgoing current range 42. The electric circuit breaker 2 is thus in its open configuration.

Afin de passer de la configuration ouverte du disjoncteur électrique 2 à sa configuration fermée, l'opérateur doit manuellement déplacer le verrou 68 vers sa deuxième position, en appuyant sur la patte 72, et connecter le module de couplage 58 du bloc disjoncteur 4 au module de couplage 64 du bloc déclencheur 6. Via le conducteur souple 59, le module 58 est déplaçable par rapport au bloc disjoncteur 4 et peut ainsi être branché sur le module 64. La patte 72, qui est entraînée par l'opérateur jusqu'en appui contre la butée 74, entraîne le reste du verrou 68 qui pivote autour de l'axe X70. Une fois couplé au module 64, le module 58 oppose à l'effort E70 du ressort 70 un effort E58, ce qui maintient le verrou 68 dans sa position d'armement. Dans sa position d'armement, le corps 680 du verrou d'armement 68 obture la niche 66 du bloc disjoncteur 6, si bien que le levier d'actionnement 52 est poussé par la surface 68B du corps 680 vers sa position armée. Le corps 680 du verrou 68 oppose à l'effort E54 du ressort 54 un effort E68 et garde le levier 52 dans sa position armée.In order to pass from the open configuration of the electric circuit breaker 2 to its closed configuration, the operator must manually move the lock 68 to its second position, by pressing on the tab 72, and connect the coupling module 58 of the circuit breaker block 4 to the coupling module 64 of the trip unit 6. Via the flexible conductor 59, the module 58 is movable relative to the circuit breaker block 4 and can thus be connected to the module 64. The tab 72, which is driven by the operator until abutting against the stop 74, causes the rest of the lock 68 which pivots about the axis X70. Once coupled to the module 64, the module 58 opposes the force E70 of the spring 70 a force E58, which keeps the latch 68 in its arming position. In its cocking position, the body 680 of the cocking lock 68 closes the niche 66 of the circuit breaker block 6, so that the actuating lever 52 is pushed by the surface 68B of the body 680 towards its armed position. The body 680 of the lock 68 opposes to the force E54 of the spring 54 a force E68 and keeps the lever 52 in its armed position.

Le levier d'actionnement 52 dans sa position armée agit mécaniquement sur l'unité de commande 50 via les moyens de connexion 56. L'unité de commande 50 peut alors déplacer le pont 46 vers sa première position où la pastille mobile 48 est en contact avec la pastille fixe 44. Un courant électrique peut donc passer entre les plages de courant entrant 41 et la plage de courant sortant 42. Le disjoncteur électrique 2 est ainsi dans sa configuration fermée.The actuating lever 52 in its armed position acts mechanically on the control unit 50 via the connection means 56. The control unit 50 can then move the bridge 46 to its first position where the mobile pellet 48 is in contact with the fixed patch 44. An electric current can thus pass between the inward current ranges 41 and the outgoing current range 42. The electric circuit breaker 2 is thus in its closed configuration.

Dans le cas où un dysfonctionnement survient à la connexion entre le bloc disjoncteur 4 et le bloc déclencheur 6, le disjoncteur 2 est configuré pour déplacer le pont 46 vers sa deuxième position où les pastilles 44 et 48 sont écartées. Ainsi, le disjoncteur interrompt tout passage de courant entre les plages 41 et 42. En particulier, lorsque une déconnexion imprévue survient aux modules de couplage 58 et 64, le verrou 68 se déplace vers sa première position et le levier 52 passe à la position désarmée et agit mécaniquement sur l'unité de commande 50 pour qu'elle déplace immédiatement le pont 64 en coupant le passage de courant entre les plages 41 et 42.In the event that a malfunction occurs at the connection between the circuit breaker block 4 and the trigger block 6, the circuit breaker 2 is configured to move the bridge 46 to its second position where the pellets 44 and 48 are spaced apart. Thus, the circuit breaker interrupts any current flow between the tracks 41 and 42. In particular, when an unexpected disconnection occurs to the coupling modules 58 and 64, the latch 68 moves to its first position and the lever 52 moves to the disarmed position. and mechanically acts on the control unit 50 to immediately move the bridge 64 by cutting the current flow between the lands 41 and 42.

Egalement, dans le cas où l'utilisateur oublie de connecter les modules 58 et 64, le disjoncteur 2 est dans sa configuration ouverte, l'unité de commande 50 gardant le pont 46 dans sa deuxième position.Also, in the case where the user forgets to connect the modules 58 and 64, the circuit breaker 2 is in its open configuration, the control unit 50 keeping the bridge 46 in its second position.

Enfin, la fonction du bloc déclencheur 6 est également assurée dans le cas de rupture d'une partie du verrou 68. Aussi bien dans le cas d'une rupture de la patte 72, que dans le cas d'une rupture du corps 680, la connexion des modules 58 et 64 ne cause pas le déplacement du levier 52 vers sa position armée par la surface 68B du verrou 68. L'unité de commande 50 garde donc le disjoncteur 2 dans sa configuration ouverte.Finally, the function of the trigger block 6 is also ensured in the case of rupture of a part of the lock 68. In the case of a break of the tab 72, as in the case of a breakage of the body 680, the connection of the modules 58 and 64 does not cause the lever 52 to move to its armed position by the surface 68B of the lock 68. The control unit 50 thus keeps the circuit breaker 2 in its open configuration.
