Description

L'invention est relative à un appareil électrique de coupure, notamment un disjoncteur ou un interrupteur modulaire, à boîtier isolant ayant une face frontale de laquelle fait saillie une manette de manoeuvre manuelle, associée au mécanisme de commande des contacts de l'appareil, ladite manette étant susceptible d'occuper deux positions extrêmes d'ouverture et de fermeture correspondant respectivement à l'état ouvert et à l'état fermé des contacts et une position intermédiaire suite à l'état de soudage des contacts.The invention relates to an electrical breaking device, in particular a circuit breaker or a modular switch, with an insulating housing having a front face from which protrudes a manual operating lever, associated with the contact control mechanism of the device, said lever being able to occupy two extreme opening and closing positions corresponding respectively to the open state and the closed state of the contacts and an intermediate position following the welding state of the contacts.

Un disjoncteur modulaire connu du genre mentionné est décrit dans les demandes de brevets français N 88 06 562 et 89 09 475. En cas de soudage des contacts, l'accés permanent de la manette rend possible un actionnement forcé au-delà de la position intermédiaire. Un cadenassage peut alors être opéré dans la position d'ouverture de la manette, alors que les contacts se trouvent soudés. La fonction de sectionnement n'est pas assurée en toute sécurité et il en résulte des risques d'accident en cas d'intervention en aval du disjoncteur.A known modular circuit breaker of the kind mentioned is described in French patent applications N 88 06 562 and 89 09 475. In the event of soldering of the contacts, the permanent access to the lever makes it possible to force actuation beyond the intermediate position . Padlocking can then be carried out in the open position of the lever, while the contacts are welded. The disconnection function is not ensured in complete safety and there is a risk of accident in the event of intervention downstream of the circuit breaker.

L'objet de l'invention consiste à interdire la condamnation de l'organe de manoeuvre d'un appareil électrique en cas de soudage des contacts.The object of the invention is to prohibit the locking of the operating member of an electrical device in the event of contact welding.

L'appareil électrique selon l'invention est caractérisé en ce qu'un module de sectionnement est adaptable à la face frontale de l'appareil, pour rendre la manette inaccessible, et comporte un organe de verrouillage équipé d'un détecteur de position de la manette, lequel est déplaçable entre une première position active dans l'état ouvert de sectionnement autorisant le blocage positif de la manette au moyen d'un dispositif de plombage ou de cadenassage, et une deuxième position inactive lorsque la manette se trouve dans la position intermédiaire interdisant la mise en place dispositif de plombage ou de cadenassage.The electrical device according to the invention is characterized in that a sectioning module is adaptable to the front face of the device, to make the lever inaccessible, and comprises a locking member equipped with a position detector of the joystick, which is movable between a first active position in the open sectioning state allowing positive locking of the joystick by means of a sealing or padlocking device, and a second inactive position when the joystick is in the intermediate position prohibiting the installation of sealing or padlocking devices.

La présence de ce module de sectionnement adaptable sur un disjoncteur modulaire permet d'obtenir un ensemble disjoncteur sectionneur à manette cadenassable en position d'ouverture. L'interdiction d'accès de la manette et l'impossibilté de cadenassage dans la position intermédiaire ouvert-soudé, contribuent à l'inviolabilité de la fonction de sectionnement de l'appareil.The presence of this sectioning module adaptable to a modular circuit breaker makes it possible to obtain a disconnector circuit breaker assembly with padlockable lever in the open position. The prohibition of access to the joystick and the impossibility of padlocking in the intermediate open-welded position, contribute to the inviolability of the sectioning function of the device.

La position exacte de la manette peut être avantageusement visualisée de l'extérieur à travers un hublot transparent prévu dans la face avant du capot du module.The exact position of the lever can advantageously be viewed from the outside through a transparent window provided in the front face of the module cover.

A l'opposé du détecteur de position de la manette, l'organe de verrouillage comporte des moyens de commande autorisant ledit plombage ou cadenassage dans une première position active.In contrast to the lever position detector, the locking member includes control means allowing said sealing or padlocking in a first active position.

Le capot comporte une cavité d'accés à la tête d'une vis de fixation du module de sectionnement sur la face frontale de l'appareil.The cover has an access cavity at the head of a screw for fixing the sectioning module on the front of the device.

L'organe de verrouillage peut être formé par un coulisseau mobile en translation, ou un culbuteur ou levier pivotant, associé à un ressort de rappel qui sollicite le détecteur en appui contre le flanc de la manette.The locking member can be formed by a slide movable in translation, or a rocker or pivoting lever, associated with a return spring which biases the detector in abutment against the side of the lever.

Dans le cas d'un disjoncteur modulaire multipolaire, le bloc de sectionnement est monté sur l'un des pôles d'extrémités, et des caches additionnels sont adaptés sur les faces frontales des autres pôles pour rendre l'ensemble inviolable.In the case of a modular multipole circuit breaker, the isolating block is mounted on one of the end poles, and additional covers are fitted on the front faces of the other poles to make the assembly inviolable.

Sur les figures 1 à 9, un module de sectionnementlo est adaptable à la face frontale 12 d'un appareil de coupure 14 à boîtier 16 isolant, notamment un disjoncteur ou un interrupteur modulaire, avec possibilité de condamnation en position d'ouverture par plombage ou cadenassage. De la face frontale 12 de l'appareil 14 fait saillie une manette 18 pivotante de manoeuvre manuelle, susceptible d'occuper deux positions extrêmes correspondant respectivement à la position d'ouverture (fig. 1) et à la position de fermeture des contacts, cette dernière position étant représentée par la trace 20 en traits pointillés.In FIGS. 1 to 9, a disconnecting module is adaptable to the front face 12 of a breaking device 14 with an insulating housing 16, in particular a circuit breaker or a modular switch, with the possibility of locking in the open position by sealing or lockout. From the front face 12 of the device 14 protrudes a pivoting lever 18 for manual operation, capable of occupying two extreme positions corresponding respectively to the open position (fig. 1) and to the closed position of the contacts, the latter position being represented by the trace 20 in lines dotted.

Le module de sectionnement 10 comporte un capot 22 isolant à fond ouvert 24 coiffant la face frontale 12 en position assemblée. La fixation du module 10 sur l'appareil 14 s'effectue sur la figure 1 au moyen d'un système d'accrochage 25 à pince autobloquante ayant une première griffe de retenue 26 fixe, et une deuxième griffe de retenue 28 articulée sur un axe 30. Une vis 32 de serrage coopère par vissage ou dévissage avec un bras de la deuxième griffe de retenue 28 pour assurer respectivement le blocage ou le déblocage du système d'accrochage 25, dont le fonctionnement est du type décrit dans le brevet français 2.572.579. Le bout de la vis 32 prend appui sur la face frontale 12, et les deux griffes 26, 28 s'incrustent dans les faces latérales opposées s'étendant perpendiculairement de part et d'autre de la face frontale 12.The isolation module 10 comprises an insulating cover 22 with an open bottom 24 covering the front face 12 in the assembled position. The attachment of the module 10 to the apparatus 14 is carried out in FIG. 1 by means of a hooking system 25 with self-locking clamp having a first retaining claw 26 fixed, and a second retaining claw 28 articulated on an axis 30. A tightening screw 32 cooperates by screwing or unscrewing with an arm of the second retaining claw 28 to respectively lock or unlock the attachment system 25, the operation of which is of the type described in French patent 2,572. 579. The end of the screw 32 bears on the front face 12, and the two claws 26, 28 are embedded in the opposite lateral faces extending perpendicularly on either side of the front face 12.

Sur la variante de la figure 6, le capot 33 s'adapte par aboutement à la face frontale 12, et l'assemblage du module de sectionnement 10 est opéré au moyen d'une ou de plusieurs vis de fixation 34 traversant la paroi de la face frontale 12.In the variant of FIG. 6, the cover 33 adapts by abutment to the front face 12, and the assembly of the sectioning module 10 is carried out by means of one or more fixing screws 34 passing through the wall of the front 12.

La face avant 35 de chaque capot 22 (fig.1) et 33 (fig.6) est dotée d'une cavité 36 d'accès à la tête de la vis 32, 34, et d'un hublot 38 transparent de visualisation de la position de la manette 18 (fig.1 et 9).The front face 35 of each cover 22 (fig. 1) and 33 (fig. 6) is provided with a cavity 36 for access to the head of the screw 32, 34, and a transparent porthole 38 for viewing the position of the lever 18 (fig. 1 and 9).

Sous le capot 22, 33 est agencé un organe de verrouillage 40 comprenant un coulisseau 42 mobile ayant un détecteur 48 de la position de la manette 18. Le coulisseau 42 est associé à un ressort 44 de traction accroché à un point fixe 46 du capot 22, et sollicitant le bout actif du détecteur 48 contre le flanc droit de la manette 18. La force de rappel du ressort 44 est faible, et est incapable d'exercer un effort notable sur la manette 18.Under the cover 22, 33 is arranged a locking member 40 comprising a movable slide 42 having a detector 48 of the position of the lever 18. The slide 42 is associated with a tension spring 44 attached to a fixed point 46 of the cover 22 , and urging the active end of the detector 48 against the right flank of the lever 18. The return force of the spring 44 is low, and is unable to exert any notable effort on the joystick 18.

A l'opposé du détecteur 48 de position, le coulisseau 42 est équipé de deux languettes 50, 52 (fig. 2 et 3) parallèles susceptibles de coulisser dans des logements 54, 56 de guidage ménagés respectivement dans deux saillies 58, 60 creuses délimitant latéralement la cavité 36 du capot 22, 33. Les saillies 58, 60 sont percées de trous 62, 64 fixes disposés en alignement, et susceptibles de coopérer avec des orifices 66, 68 prévus aux extrémités des languettes 50, 52 mobiles, lorsque le coulisseau 42 se trouve dans la position active de la figure 1, correspondant à l'ouverture de l'appareil 14. Un fil de plombage 70 (fig.7), ou un dispositif de cadenassage 72 (fig.8) du type décrit dans le brevet français 2.569.046 peut alors être mis en place suite à la coïncidence des trous 62, 64 du capot 22, 33, et des orifices 66, 68 du coulisseau 42.Opposite the position detector 48, the slide 42 is equipped with two parallel tongues 50, 52 (fig. 2 and 3) capable of sliding in guide housings 54, 56 formed respectively in two hollow projections 58, 60 delimiting laterally the cavity 36 of the cover 22, 33. The projections 58, 60 are pierced with fixed holes 62, 64 arranged in alignment, and capable of cooperating with orifices 66, 68 provided at the ends of the movable tongues 50, 52, when the slide 42 is in the active position of FIG. 1, corresponding to the opening of the device 14. A sealing wire 70 (fig. 7), or a padlocking device 72 (fig. 8) of the type described in the French patent 2,569,046 can then be put in place following the coincidence of the holes 62, 64 of the cover 22, 33, and the orifices 66, 68 of the slide 42.

Un trou 74 supplémentaire est ménagé dans la tête de la vis 32, 34 pour assurer le plombage de l'organe de fixation du module 10 sur l'appareil 14.An additional hole 74 is provided in the head of the screw 32, 34 to seal the module 10 fixing member on the device 14.

La mise en oeuvre du module de sectionnement 10 sur l'appareil 14 est la suivante :The implementation of the sectioning module 10 on the device 14 is as follows:

Dans l'état de fermeture de l'appareil 14, la manette 18 se trouve en saillie dans la position relevée (voir trace 20 en pointillé sur fig.1), et empêche toute tentative d'installation du module de sectionnement 10 sur la face frontale 12 par butée de la face inférieure du coulisseau 42 sur la manette 18.In the closed state of the device 14, the lever 18 is projecting in the raised position (see trace 20 in dotted lines in fig.1), and prevents any attempt to install the sectioning module 10 on the face front 12 by stop on the lower face of the slide 42 on the lever 18.

La mise en place du module de sectionnement 10 sur l'appareil 14 est autorisé lorsque la manette 18 se trouve dans la position d'ouverture (fig.1) ou dans la position ouvert-soudé (fig. 6). Le capot 22, 33 du module 10 coiffe la face frontale 12 de l'appareil 14, et il suffit de serrer la vis 32, 34 pour l'assemblage définitif.The installation of the sectioning module 10 on the device 14 is authorized when the lever 18 is in the open position (fig. 1) or in the open-welded position (fig. 6). The cover 22, 33 of the module 10 covers the front face 12 of the device 14, and it suffices to tighten the screw 32, 34 for the final assembly.

Dans l'état d'ouverture de l'appareil 14 (fig.1), le détecteur 48 se trouve dans une première position active de fin de course en appui sur la manette 18, de manière à faire coïncider les orifices 66, 68 des languettes 50, 52 avec les trous 62, 64 des saillies 58, 60 du capot 22. La présence du capot 22 interdit l'accès à la manette 18, et un plombage ou cadenassage du module 10 est possible par introduction du fil de plombage 70 ou du dispositif de cadenassage 72 dans les trous 62, 64 du capot 22 et les orifices 66, 68 du coulisseau 42. La manette 18 est alors verrouillée positivement par le coulisseau 42, et l'appareil 14 se comporte comme un disjoncteur sectionneur modulaire cadenassé en position d'ouverture. L'état d'ouverture de l'appareil 14 est visible à travers le hublot 38, et la fonction de cadenassage permet de s'assurer que le disjoncteur est effectivement sectionné sans aucun risque de soudage des contacts.In the open state of the device 14 (fig. 1), the detector 48 is in a first active end-of-travel position bearing on the lever 18, so as to make the orifices 66, 68 of the tabs 50, 52 with the holes 62, 64 of the projections 58, 60 of the cover 22. The presence of the cover 22 prevents access to the handle 18, and sealing or padlocking of the module 10 is possible by introducing the sealing wire 70 or of the padlocking device 72 in the holes 62, 64 of the cover 22 and the orifices 66, 68 of the slide 42. The lever 18 is then positively locked by the slide 42, and the device 14 behaves like a padlocked modular disconnector circuit breaker in the open position. The opening state of the device 14 is visible through the window 38, and the lockout function makes it possible to ensure that the circuit breaker is effectively cut off without any risk of soldering the contacts.

Le fil de plombage 70 peut en plus passer par le trou 74 de la tête de vis 32, 34 pour assurer le plombage du moyen de fixation du module de sectionnement 10 sur l'appareil 14.The sealing wire 70 can additionally pass through the hole 74 of the screw head 32, 34 in order to seal the means for fixing the sectioning module 10 to the device 14.

En plus de sa fonction de cadenassage de la manette 18, le mise en place du dispositif de cadenassage 72 dans la cavité 36 du capot 22 interdit automatiquement l'accès à la tête de vis 32, 34, et empêche toute tentative de démontage du module 10.In addition to its function of padlocking the lever 18, the installation of the padlocking device 72 in the cavity 36 of the cover 22 automatically prevents access to the screw head 32, 34, and prevents any attempt to dismantle the module. 10.

Dans l'état soudé des contacts, le débattement de la manette 18 est limité à une position intermédiaire ouvert-soudé, représentée à la figure 6. La mise en place sur l'appareil 14 du capot 33 du module de sectionnement 10 est autorisé ainsi que le serrage de la vis 34. Par contre, le plombage ou cadenassage est rendu impossible suite au déplacement du coulisseau 42 vers une deuxième position inactive représentant la position intermédiaire de la manette 18. Les trous 62, 64 des saillies 58, 60 ne sont plus en coïncidence avec les orifices 66, 68 des languettes 50, 52, ce qui interdit le passage du fil de plombage 70, et l'adaptation du dispositif de cadenassage 72.In the welded state of the contacts, the clearance of the lever 18 is limited to an open-welded intermediate position, shown in FIG. 6. The installation on the device 14 of the cover 33 of the sectioning module 10 is thus authorized that the tightening of the screw 34. On the other hand, the sealing or padlocking is made impossible following the displacement of the slide 42 towards a second inactive position representing the intermediate position of the lever 18. The holes 62, 64 of the projections 58, 60 are not more in coincidence with the orifices 66, 68 of the tongues 50, 52, which prohibits the passage of the sealing wire 70, and the adaptation of the padlocking device 72.

L'impossibilité de cadenasser le coulisseau 42 prouve que l'appareil 14 n'est pas sectionné suite à l'état de soudage des contacts.The impossibility of padlocking the slide 42 proves that the device 14 is not cut off following the state of welding of the contacts.

L'encombrement du module de sectionnement 10 correspond à celui d'un pôle de disjoncteur, c'est à dire 18 mn. Le disjoncteur tétrapolaire (fig.2) reçoit le module de sectionnement 10 sur l'un des pôles d'extrémités, celui de droite par exemple, tandis que les trois autres pôles sont coiffés par des caches 80 modulaires, qui interdisent l'accès aux manettes corespondantes. Le cache 80 (fig.4, 5 et 9) de chaque pôle est dépourvu de coulisseau de verrouillage, et comporte un simple capot isolant assujetti au pôle adjacent par deux liaisons à tenon-mortaise 82, 84, ou par tout autre système de fixation à encliquetage ou clipsage. L'ensemble caches 80 et module de sectionnement 10 cadenassé du disjoncteur tétrapolaire est inviolable après montage.The size of the isolation module 10 corresponds to that of a circuit breaker pole, that is to say 18 min. The four-pole circuit breaker (fig. 2) receives the sectioning module 10 on one of the end poles, the one on the right for example, while the other three poles are capped by modular covers 80, which prevent access to the corresponding joysticks. The cover 80 (fig. 4, 5 and 9) of each pole is devoid of locking slide, and comprises a simple insulating cover secured to the adjacent pole by two mortise-mortise connections 82, 84, or by any other fixing system latching or clipping. The assembly of covers 80 and sectioning module 10 padlocked of the four-pole circuit breaker is tamper-proof after mounting.

Sur la variante de la figure 10, l'organe de verrouillage 40 du module de sectionnement 10 est formé par un culbuteur 86 susceptible de basculer le long d'une ouverture 88 oblongue du capot 22 en fonction de la position du détecteur 148 en appui sur la manette 18. En position ouvert non soudé des contacts, le trou 90 du culbuteur 86 vient en coïncidence avec l'orifice 92 du capot 22 pour permettre le plombage ou le cadenassage du module 100 sur l'appareil 14.In the variant of FIG. 10, the locking member 40 of the sectioning module 10 is formed by a rocker arm 86 capable of tilting along an oblong opening 88 of the cover 22 as a function of the position of the detector 148 pressing on the lever 18. In the open, non-welded position of the contacts, the hole 90 of the rocker arm 86 coincides with the orifice 92 of the cover 22 to allow the sealing or padlocking of the module 100 on the device 14.

Sur la figure 11, l'organe de verrouillage 40 du module de sectionnement 200 comporte un levier 94 de commande monté à pivotement sur un axe 96 entre une première position active (traits pleins) correspondant à la position ouvert autorisant le cadenassage, et une deuxième position inactive correspondant à la position ouvert-soudé ne permettant pas le cadenassage. Un trou 262 est ménagé dans le capot 22 pour autoriser le passage du fil de plombage 70 ou du dispositif de cadenassage 72 provoquant le verrouillage du levier 262 dans ladite première position active. L'axe 96 est parallèle à l'axe de basculement de la manette 18.In FIG. 11, the locking member 40 of the sectioning module 200 comprises a control lever 94 pivotally mounted on an axis 96 between a first active position (solid lines) corresponding to the open position allowing padlocking, and a second inactive position corresponding to the open-welded position not allowing padlocking. A hole 262 is formed in the cover 22 to allow the passage of the sealing wire 70 or the padlocking device 72 causing the locking of the lever 262 in said first active position. The axis 96 is parallel to the pivot axis of the lever 18.
