Objet de l'inventionSubject of the invention

L'objet de l'invention consiste à réaliser un module auxiliaire de signalisation ayant au moins un commutateur facilement commutable en version OF ouvert - fermé, ou SD armé - déclenché.The object of the invention is to provide an auxiliary signaling module having at minus one easily switchable switch in open - closed OF version, or armed SD - sets off.

Le module auxiliaire de signalisation selon l'invention est caractérisé en ce qu'un levier de signalisation signal défaut SD est monté sur la platine du mécanisme, et que le contact mobile du deuxième commutateur est actionné par un levier intermédiaire, lequel suit le déplacement de la platine ou du levier de signalisation en fonction du réglage du sélecteur, respectivement pour le choix du mode de fonctionnement OF ouvert - fermé, ou SD armé - déclenché.The auxiliary signaling module according to the invention is characterized in that a lever for SD fault signaling is mounted on the mechanism plate, and that the contact mobile of the second switch is actuated by an intermediate lever, which follows the displacement of the plate or the signaling lever according to the setting of the selector, respectively for the choice of the operating mode OF open - closed, or SD armed - triggered.

Selon un mode de réalisation préférentiel, le levier intermédiaire est monté à pivotement sur un axe dont le positionnement est modifié lors de l'ajustage du sélecteur. Le contact mobile du premier commutateur est actionné par la platine rotative, et le levier de signalisation SD à voyant bistable est monté à pivotement sur un pivot de la platine entre une position armée et une position déclenchée.According to a preferred embodiment, the intermediate lever is pivotally mounted on an axis whose position is modified when the selector is adjusted. The contact of the first switch is actuated by the rotary plate, and the lever SD signaling with bistable indicator is pivotally mounted on a turntable pivot between an armed position and a triggered position.

Selon une caractéristique de l'invention, le sélecteur est accouplé à un indicateur de commutation destiné à visualiser le mode de fonctionnement OF-OF ou SD-OF depuis la face avant du boítier. Le choix du mode de fonctionnement intervient avant l'accouplement avec l'appareillage. La commutation du sélecteur devient impossible lorsque le module auxiliaire de signalisation est accolé et accouplé au disjoncteur, car le sélecteur n'est plus accessible. According to a characteristic of the invention, the selector is coupled to an indicator of switching intended to display the OF-OF or SD-OF operating mode from the front of the housing. The choice of operating mode occurs before coupling with the equipment. Switching of the selector becomes impossible when the module signaling auxiliary is coupled and coupled to the circuit breaker, because the selector is no longer accessible.

Description d'un mode de réalisation préférentielDescription of a preferred embodiment

En référence aux figures 1 à 6, un module auxiliaire de signalisation 10 est logé dans un boítier 12 isolant destiné à être accolé et accouplé à un appareillage électrique à déclencheur, notamment un disjoncteur ou un interrupteur différentiel à basse tension. Le boítier 12 renferme deux commutateurs 14, 16 électriques actionnés par un mécanisme 18 de commande, lequel est piloté par des liaisons mécaniques de déclenchement et de réarmement de l'appareillage électrique.With reference to FIGS. 1 to 6, an auxiliary signaling module 10 is housed in a insulating housing 12 intended to be attached to and coupled to an electrical apparatus with trip device, in particular a circuit breaker or a low voltage differential switch. The box 12 contains two electrical switches 14, 16 actuated by a mechanism 18 which is controlled by mechanical triggering and resetting of the electrical equipment.

Chaque commutateur 14, 16 est doté d'un contact mobile 20, 22 inverseur formé par une lame métallique flexible coopérant avec une paire de contacts fixes 24, 26; 28, 30 isolés l'un de l'autre. Le premier commutateur 14 de droite indique en permanence une signalisation OF de l'état ouvert -fermé des contacts de l'appareillage, tandis que le deuxième commutateur 16 de gauche indique soit une signalisation OF ouvert -fermé, soit une signalisation SD signal défaut en fonction de la position d'un sélecteur 32 rotatif. Each switch 14, 16 is provided with a movable contact 20, 22 reverser formed by a flexible metal blade cooperating with a pair of fixed contacts 24, 26; 28, 30 isolated one of the other. The first switch 14 on the right permanently indicates a OF signaling of the open-closed state of the switchgear contacts, while the second switch 16 on the left indicates either an open-closed OF signaling, or SD signaling fault signal depending on the position of a rotary selector 32.

Les contacts fixes 24, 26 et le contact mobile 20 du premier commutateur 14 sont reliés électriquement à des bornes de raccordement 34, 36, 38 logées dans des alvéoles de la face latérale de droite du boítier 12. Les contacts fixes 28, 30 et le contact mobile 22 du deuxième commutateur 16 sont reliés électriquement à des bornes de raccordement 40, 42, 44 logées dans des alvéoles de la face latérale de gauche du boítier 12.The fixed contacts 24, 26 and the movable contact 20 of the first switch 14 are connected electrically to connection terminals 34, 36, 38 housed in cells of the right side face of the housing 12. The fixed contacts 28, 30 and the movable contact 22 of the second switch 16 are electrically connected to connection terminals 40, 42, 44 housed in cells on the left side face of the housing 12.

Le module auxiliaire de signalisation 10 est pourvu d'une manette 46 montée à pivotement sur un axe 48, et reliée au crochet d'accrochage du mécanisme 18 par une biellette de transmission 50. Le mécanisme 18 comporte une platine 52 rotative entre deux positions extrêmes qui indique en permanence l'état ouvert -fermé des contacts du disjoncteur, et une barre de déclenchement 54 destinée à recevoir un ordre de déclenchement du disjoncteur. Sur le pivot 56 de la platine 52 est monté à rotation un levier de signalisation 58 signal défaut SD qui indique en permanence l'état armé-déclenché du disjoncteur. L'extrémité du levier de signalisation 58 comprend à cet effet un voyant 60 bistable visible depuis la face avant 62 du boítier 12.The auxiliary signaling module 10 is provided with a lever 46 pivotally mounted on an axis 48, and connected to the hook for hooking the mechanism 18 by a connecting rod transmission 50. The mechanism 18 comprises a plate 52 rotatable between two positions which permanently indicates the open-closed state of the circuit breaker contacts, and a trigger bar 54 intended to receive a trigger order from the breaker. On the pivot 56 of the plate 52 is rotatably mounted a signaling lever 58 SD fault signal which permanently indicates the armed-tripped state of the circuit breaker. The end of the signaling lever 58 includes for this purpose a visible bistable indicator 60 from the front face 62 of the housing 12.

Le contact mobile 20 du premier commutateur 14 est actionné par la platine 52, tandis que le contact mobile 22 du deuxième commutateur 16 est entraíné par un levier intermédiaire 62 monté à pivotement sur un axe 64.The movable contact 20 of the first switch 14 is actuated by the plate 52, while the movable contact 22 of the second switch 16 is driven by an intermediate lever 62 pivotally mounted on an axis 64.

Le sélecteur 32 a deux positions stables de réglage, et est accessible depuis la grande face latérale de droite du boítier 12 constituant la face d'accolement avec le disjoncteur. Le réglage du sélecteur 32 est opéré manuellement au moyen d'un tourne -vis, et permet à l'utilisateur de choisir entre deux modes de fonctionnement du module auxiliaire de signalisation 10, à savoir un premier mode OF-OF, et un deuxième mode SD-OF. Le choix du mode de fonctionnement intervient avant l'accouplement avec le disjoncteur. La commutation devient impossible lorsque le module auxiliaire de signalisation 10 est accolé et accouplé au disjoncteur, car le sélecteur 32 n'est plus accessible.The selector 32 has two stable adjustment positions, and is accessible from the large right side face of the housing 12 constituting the face of contact with the circuit breaker. The selector adjustment 32 is operated manually by means of a screwdriver, and allows the user to choose between two operating modes of the auxiliary module of signaling 10, namely a first OF-OF mode, and a second SD-OF mode. The choice of the operating mode occurs before coupling with the circuit breaker. The switching becomes impossible when the auxiliary signaling module 10 is attached and coupled to the circuit breaker, because the selector 32 is no longer accessible.

Selon la position angulaire du sélecteur 32, le levier intermédiaire 62 d'entraínement du contact mobile 22 du deuxième commutateur 16 vient en appui sur la platine 52 (figures 1 à 3) ou sur le levier de signalisation 58 signal défaut SD (figures 4 à 6). Le changement de position du sélecteur 32 provoque une modification du positionnement de l'axe 64 du levier intermédiaire 62. Depending on the angular position of the selector 32, the intermediate lever 62 for driving the movable contact 22 of the second switch 16 bears on the plate 52 (Figures 1 to 3) or on the signaling lever 58 SD fault signal (Figures 4 to 6). The change of position of the selector 32 causes a modification of the positioning of the axis 64 of the lever intermediate 62.

Le sélecteur 32 entraíne de plus un indicateur de commutation 66 qui visualise en face avant 62 le fonctionnement choisi. En fonctionnement OF du deuxième commutateur 16, le levier intermédiaire 62 suit la platine 52. En fonctionnement SD du deuxième commutateur 16, le levier intermédiaire 62 est entraíné par le levier de signalisation 58 signal défaut SD.The selector 32 also drives a switching indicator 66 which displays opposite before 62 the chosen operation. In OF operation of the second switch 16, the intermediate lever 62 follows the plate 52. In SD operation of the second switch 16, the intermediate lever 62 is driven by the signaling lever 58 SD fault signal.

Un ressort de traction 68 est agencé entre un point fixe 70 du boítier 12, et le levier de signalisation 58 signal défaut SD. Le ressort 68 se trouve dans l'état tendu en cas de non déclenchement lorsque le disjoncteur est en position de fermeture ou ouvert par une action manuelle. Le levier de signalisation 58 signal défaut SD est alors en position armée (figures 1-2 et 4-5).A tension spring 68 is arranged between a fixed point 70 of the housing 12, and the lever signaling 58 SD fault signal. Spring 68 is in the stretched state in case of non tripping when the circuit breaker is in the closed position or opened by a manual action. The signaling lever 58 SD fault signal is then in the armed position (Figures 1-2 and 4-5).

Le ressort 68 revient dans l'état détendu en cas de déclenchement automatique du disjoncteur, et sollicite le levier de signalisation 58 signal défaut SD vers la position déclenchée (figures 3 et 6). Spring 68 returns to the relaxed state in the event of automatic triggering of the circuit breaker, and requests the signaling lever 58 SD fault signal towards the position triggered (Figures 3 and 6).

Fonctionnement en mode OF-OFOperation in OF-OF mode

Le fonctionnement du module auxiliaire de signalisation 10 en version OF-OF est illustré sur les figures 1-3. Le sélecteur 32 est réglé dans une position donnée qui positionne le levier intermédiaire 62 en appui sur la platine 52. Le deuxième commutateur 16 indique comme le premier commutateur 14, l'état ouvert -fermé OF du disjoncteur. Le réglage du mode de fonctionnement OF-OF est affiché en face avant 62 par l'indicateur de commutation 66.The operation of the auxiliary signaling module 10 in OF-OF version is illustrated in Figures 1-3. The selector 32 is set in a given position which positions the intermediate lever 62 resting on the plate 52. The second switch 16 indicates like the first switch 14, the open-closed state OF of the circuit breaker. The setting of the OF-OF operating mode is displayed on the front panel 62 by the switching 66.

Sur la figure 1, le module auxiliaire de signalisation 10 est en position fermé, et les deux contacts mobiles 20, 22 sont en engagement contre les contacts fixes 24, 28 en reflétant tous les deux le positionnement de la platine 52 en indiquant l'état fermé du disjoncteur. Le levier de signalisation 58 signal défaut SD est en position armée, et le ressort 68 se trouve dans l'état tendu.In FIG. 1, the auxiliary signaling module 10 is in the closed position, and the two movable contacts 20, 22 are engaged against the fixed contacts 24, 28 reflecting both positioning of the plate 52 indicating the closed state of the circuit breaker. The signaling lever 58 SD fault signal is in the armed position, and spring 68 is located in the tense state.

La figure 2 représente la phase d'ouverture manuelle du disjoncteur, dans laquelle la manette 46 du module auxiliaire de signalisation 10 pivote en sens inverse des aiguilles d'une montre, entraínant la platine 52 rotative dans le même sens. Les deux contacts mobiles 20, 22 sont déplacés simultanément par la platine 52 dans le même sens, et viennent en engagement contre les contacts fixes 26, 30 en indiquant tous les deux l'état ouvert du disjoncteur. Le levier de signalisation 58 signal défaut SD reste immobile durant l'ouverture manuelle du disjoncteur, et n'a aucune influence sur le levier intermédiaire 62, étant donné que le contact mobile 22 suit exclusivement le déplacement de la platine 52.Figure 2 shows the manual opening phase of the circuit breaker, in which the lever 46 of the auxiliary signaling module 10 pivots anticlockwise of a watch, driving the turntable 52 in the same direction. The two contacts mobile 20, 22 are moved simultaneously by the plate 52 in the same direction, and come into engagement against the fixed contacts 26, 30 both indicating the state open the circuit breaker. The signaling lever 58 SD fault signal remains stationary during manual opening of the circuit breaker, and has no influence on the intermediate lever 62, since the movable contact 22 exclusively follows the movement of the plate 52.

En cas de déclenchement du disjoncteur (figure 3), la barre de déclenchement 54 provoque le déverrouillage de la platine 52, laquelle se déplace dans la même position que celle représentée dans la figure 2, mais plus rapidement. Les deux contacts mobiles 20, 22 sont déplacés simultanément par la platine 52 dans le même sens, et viennent en engagement contre les contacts fixes 26, 30 en indiquant tous les deux l'état ouvert du disjoncteur. Le levier de signalisation 58 signal défaut SD est sollicité par le ressort 68 vers le position déclenchée de manière à indiquer le mode d'ouverture du disjoncteur par déclenchement.If the circuit breaker trips (Figure 3), the trip bar 54 causes the plate 52 to be unlocked, which moves to the same position as that shown in Figure 2, but faster. The two movable contacts 20, 22 are moved simultaneously by the plate 52 in the same direction, and come into engagement against the fixed contacts 26, 30 both indicating the open state of the breaker. The signaling lever 58 SD fault signal is biased by the spring 68 towards the tripped position so as to indicate the opening mode of the circuit breaker by trigger.

Les deux commutateurs 14, 16 fonctionnent en mode ouvert-fermé OF, et le levier intermédiaire 62 suit la platine 52 et non pas levier de signalisation 58 signal défaut SD. Ce dernier n'est pas bloqué pour autant, car il indique le déclenchement du disjoncteur. The two switches 14, 16 operate in open-closed OF mode, and the lever intermediate 62 follows the plate 52 and not the signaling lever 58 SD fault signal. The latter is not blocked, however, because it indicates that the circuit breaker has tripped.

Fonctionnement en mode SD-OFSD-OF mode operation

Le fonctionnement du module auxiliaire de signalisation 10 en version SD-OF est illustré sur les figures 4-6. Le sélecteur 32 est commuté au moyen d'un tourne -vis sur l'autre position, qui modifie l'emplacement de l'axe 64 de pivotement du levier intermédiaire 62. Ce dernier vient en appui sur le levier de signalisation 58 signal défaut SD, et le réglage du mode de fonctionnement SD-OF est affiché en face avant 62 par l'indicateur de commutation 66 qui pivote vers la droite. Le premier commutateur 14 piloté par la platine 52 indique toujours l'état ouvert -fermé OF du disjoncteur, et le deuxième commutateur 16 commandé par le levier de signalisation 58 indique l'état armé -déclenché SD du disjoncteur.The operation of the auxiliary signaling module 10 in SD-OF version is illustrated in Figures 4-6. The selector 32 is switched by means of a screwdriver on the other position, which modifies the location of the pivot axis 64 of the intermediate lever 62. The latter comes to bear on the signaling lever 58 SD fault signal, and the adjustment of the SD-OF operating mode is displayed on the front panel 62 by the switching 66 which pivots to the right. The first switch 14 controlled by the plate 52 always indicates the open-closed state OF of the circuit breaker, and the second switch 16 controlled by signaling lever 58 indicates the armed-tripped state SD of the breaker.

Sur la figure 4, le module auxiliaire de signalisation 10 est en position de fermeture, et les contacts mobiles 20, 22 sont en engagement contre les contacts fixes 26, 28. Le premier commutateur 14 indique l'état fermé des contacts du disjoncteur, et le deuxième commutateur 16 signale l'état armé du disjoncteur.In FIG. 4, the auxiliary signaling module 10 is in the closed position, and the movable contacts 20, 22 are engaged against the fixed contacts 26, 28. The first switch 14 indicates the closed state of the circuit breaker contacts, and the second switch 16 signals the armed state of the circuit breaker.

Lors d'une ouverture manuelle du disjoncteur (figure 5), la manette 46 du module auxiliaire de signalisation 10 pivote en sens inverse des aiguilles d'une montre, entraínant la platine 52 rotative dans le même sens. Le contact mobile 20 est actionné vers le contact fixe 26, et le premier commutateur 14 signale l'état ouvert des contacts du disjoncteur. Le levier de signalisation 58 se maintient immobile en position armée, et n'entraíne pas le levier intermédiaire 62 qui reste dans la même position que celle de la figure 4. Le contact mobile 22 reste en engagement contre le contact fixe 28, et le deuxième commutateur 16 confirme l'état armé du disjoncteur.When the circuit breaker is opened manually (Figure 5), the handle 46 of the auxiliary module signal 10 rotates counterclockwise, driving the plate 52 rotating in the same direction. The movable contact 20 is actuated towards the fixed contact 26, and the first switch 14 signals the open state of the contacts of the circuit breaker. The lever signaling 58 remains stationary in the armed position, and does not drive the lever intermediate 62 which remains in the same position as that of FIG. 4. The contact mobile 22 remains in engagement against the fixed contact 28, and the second switch 16 confirms the armed state of the circuit breaker.

En cas de déclenchement du disjoncteur (figure 6), la barre de déclenchement 54 provoque le déverrouillage de la platine 52, laquelle se déplace dans la même position que celle représentée dans la figure 5, mais plus rapidement que la manette. Les deux contacts mobiles 20, 22 sont déplacés simultanément dans le même sens contre les contacts fixes 26, 30, l'un par l'action de la platine 52, et l'autre par le levier intermédiaire 62 entraíné par le levier de signalisation 58. Le premier commutateur 14 signale l'état ouvert des contacts du disjoncteur, et le deuxième commutateur 16 signale le déclenchement du disjoncteur suite au passage du levier de signalisation 58 vers la position déclenchée. If the circuit breaker trips (Figure 6), the trip bar 54 causes the plate 52 to be unlocked, which moves to the same position as that shown in Figure 5, but faster than the joystick. Both movable contacts 20, 22 are moved simultaneously in the same direction against the fixed contacts 26, 30, one by the action of the plate 52, and the other by the intermediate lever 62 driven by the signaling lever 58. The first switch 14 signals the state open circuit breaker contacts, and the second switch 16 signals the tripping of the circuit breaker following passage of the signaling lever 58 towards the triggered position.

A partir de la position de la figure 6, le réarmement du module auxiliaire de signalisation 10 s'effectue lors d'une fermeture manuelle du disjoncteur qui provoque le déplacement de la platine 52 vers la position de la figure 4. La rotation de la manette 46 et de la platine 52 dans le sens des aiguilles d'une montre, entraíne le levier de signalisation 58 dans le même sens vers la position armé. Il est aussi possible d'opérer directement le réarmement en déplaçant le voyant 60 de la position déclenchée (figure 6) vers la position armée (figure 4).From the position of figure 6, the rearming of the auxiliary signaling module 10 takes place during a manual closing of the circuit breaker which causes the displacement of the plate 52 towards the position of FIG. 4. The rotation of the lever 46 and of the plate 52 clockwise, drives the signaling lever 58 in the same direction towards the armed position. It is also possible to operate the rearming directly by moving the indicator 60 from the triggered position (Figure 6) to the armed position (figure 4).
