L'excitation de l'électro-aimant 52 est active en fin de course de fermeture, lorsque le rupteur 48 est actionné par le levier de commutation 46 vers la position B du sélecteur 50. Dans cette position, le moteur 32 se trouve à l'arrêt suite à l'interruption de son alimentation, et l'électro-aimant 52 est excité à travers un redresseur 62.The electrical supply of the motor 32 is effected by two wires 58, 60 (FIG. 2), one of which 58 is connected to the terminal 30, and the other of which 60 is connected to the terminal 28 through the switch 48 when the latter is in position A. The excitation of the electromagnet 52 is active at the end of the closing stroke, when the breaker 48 is actuated by the switching lever 46 towards the position B of the selector 50. In in this position, the motor 32 is stopped after its supply has been interrupted, and the electromagnet 52 is excited through a rectifier 62.

En référence aux figures 7 et 8, l'électro-aimant 52 comporte un circuit magnétique fixe 64 et un noyau mobile 66 sollicité vers une position écartée de repos par un ressort de rappel 68. Le noyau 66 coulissant est accouplé à une branche d'un levier de blocage 70, lequel est monté à pivotement limité sur un axe 72 entre une position active de verrouillage d'une roue dentée 74 de l'embrayage centrifuge 36, et une position inactive de déverrouillage de la roue 74.Referring to Figures 7 and 8, the electromagnet 52 comprises a fixed magnetic circuit 64 and a movable core 66 biased towards a position apart from rest by a return spring 68. The sliding core 66 is coupled to a branch of a locking lever 70, which is pivotally mounted on an axis 72 between an active position for locking a toothed wheel 74 of the centrifugal clutch 36, and an inactive position for unlocking the wheel 74.

Le fonctionnement du bloc de télécommande 10 selon les figures 1-8 est le suivant :The operation of the remote control unit 10 according to FIGS. 1-8 is as follows:

Enclenchement du disjoncteur : Circuit breaker engagement :

La fermeture du disjoncteur 12 par l'action du bloc de télécommande 10 est opérée par la mise sous tension du moteur 32, le rupteur 48 du sélecteur 50 étant dans la position A. L'électro-aimant 52 n'est pas alimenté, et le levier de blocage 70 se trouve dans la position inactive (figure 7), autorisant l'entraînement de l'embrayage 36 centrifuge suite à la rotation du moteur 32. Le réducteur de vitesse 34 agit sur la biellette de transmission 40 articulée sur un axe 76 excentré du pignon 38, de manière à déplacer la manette 22 pivotante vers la position de fermeture (indiquée en pointillé sur la figure 5). Toute l'énergie de fermeture est ainsi transmise par le moteur 38, lequel fournit simultanément l'énergie d'armement du ressort d'ouverture 44 par l'intermédiaire du pignon auxiliaire 42.
En fin de course de fermeture, la biellette de transmission est désaccouplée de la manette 22, et le levier de commutation 46 est actionné par le pignon 38 dans le sens horaire pour déplacer le rupteur 48 du sélecteur 50 vers la position B sous l'action du poussoir 56 (figure 8). La commutation du sélecteur 50 interrompt l'alimentation du moteur 32, et assure l'excitation de l'électro-aimant 52. L'attraction du noyau mobile 66 provoque le basculement dans le sens anti-horaire du levier de blocage 70 vers la position active de verrouillage d'une dent de la roue 74, de manière à bloquer l'embrayage 36, et à empêcher le retour du réducteur 34 sous l'action de la force de rappel du ressort d'ouverture 44.
Le disjoncteur reste verrouillé en position de fermeture, et le rupteur 48 est maintenu dans la position B pour alimenter un permanence l'électro-aimant 52 jusqu'à l'émission d'un ordre d'ouverture.The circuit breaker 12 is closed by the action of the remote control unit 10 by operating the motor 32, the breaker 48 of the selector 50 being in position A. The electromagnet 52 is not supplied, and the locking lever 70 is in the inactive position (FIG. 7), authorizing the drive of the centrifugal clutch 36 following the rotation of the motor 32. The speed reducer 34 acts on the transmission link 40 articulated on an axis 76 eccentrically of the pinion 38, so as to move the pivoting lever 22 towards the closed position (indicated in dotted lines in FIG. 5). All the closing energy is thus transmitted by the motor 38, which simultaneously supplies the arming energy of the opening spring 44 via the auxiliary pinion 42.
At the end of the closing stroke, the transmission link is uncoupled from the lever 22, and the switching lever 46 is actuated by the pinion 38 clockwise to move the switch 48 from the selector 50 to the position B under the action. pusher 56 (Figure 8). The switching of the selector 50 interrupts the supply of the motor 32, and ensures the excitation of the electromagnet 52. The attraction of the movable core 66 causes the tilting lever anticlockwise 70 towards the position active locking of a tooth of the wheel 74, so as to block the clutch 36, and to prevent the return of the reduction gear 34 under the action of the return force of the opening spring 44.
The circuit breaker remains locked in the closed position, and the breaker 48 is held in the position B to permanently supply the electromagnet 52 until an opening order is issued.

Ouverture du disjoncteur : Breaker opening :

L' ouverture des contacts du disjoncteur 12 par l'action du bloc de télécommande 10 s'effectue par la mise hors tension des bornes 28, 30, entraînant la désexcitation de l'électro-aimant 52. Le noyau 66 mobile revient vers la position écartée sous l'action de son ressort de rappel 68 (figure 7), et provoque le pivotement du levier de blocage 70 dans le sens horaire vers la position inactive de déverrouillage de la roue dentée 74. Il en résulte la libération du réducteur 34, autorisant la détente du ressort d'ouverture 44, et la rotation du pignon 38 entraînant la manette 22 vers la position d'ouverture (figure 5). L'embrayage centrifuge 36 reste débrayé pendant la phase d'ouverture, car le moteur 32 ne tourne pas, étant hors tension jusqu'au prochain ordre de fermeture.The opening of the contacts of the circuit breaker 12 by the action of the remote control unit 10 is effected by switching off the terminals 28, 30, causing the electromagnet 52 to de-energize. The movable core 66 returns to the position separated by the action of its return spring 68 (FIG. 7), and causes the locking lever 70 to pivot clockwise towards the inactive unlocking position of the toothed wheel 74. This results in the release of the reduction gear 34, authorizing the expansion of the opening spring 44, and the rotation of the pinion 38 driving the handle 22 towards the open position (Figure 5). The centrifugal clutch 36 remains disengaged during the opening phase, because the motor 32 does not turn, being de-energized until the next closing order.

Au début de la phase d'ouverture, le pignon 38 libère le levier de commutation 46 permettant la commutation du rupteur 48 vers la position A. Cette commutation intervient avant le rétablissement de la liaison mécanique entre la biellette de transmission 40 et la manette 22.At the start of the opening phase, the pinion 38 releases the switching lever 46 allowing the switch 48 to switch to position A. This switching takes place before the mechanical link between the transmission link 40 and the lever 22 is re-established.

Le bloc de télécommande 10 fonctionne comme un contacteur. En présence de la tension aux bornes 28, 30, le disjoncteur télécommandé est fermé tandis que l'absence de tension aux bornes 28, 30 engendre l'ouverture du disjoncteur télécommandé. La biellette de transmission 40 escamotable permet une action manuelle d'ouverture et de fermeture, par exemple en cas de non fonctionnement du donneur d'ordre du bloc de télécommande 10.The remote control unit 10 functions as a contactor. In the presence of the voltage at terminals 28, 30, the remote-controlled circuit breaker is closed while the absence of voltage at terminals 28, 30 generates the opening of the remote-controlled circuit breaker. The retractable transmission link 40 allows manual opening and closing action, for example in the event of non-operation of the client of the remote control unit 10.

L'assemblage du bloc de télécommande 10 au disjoncteur 12 (figure 1) s'effectue lorsque la barre de déclenchement 24 à l'intérieur du boîtier 11 du bloc de télécommande se trouve en regard de la barre de déclenchement du disjoncteur 12. Pour des raisons de sécurité au montage, le disjoncteur 12 doit être dans l'état ouvert, ce qui implique une concordance d'état pour le bloc de télécommande 10. Le bloc de télécommande 10 se trouve à l'état ouvert (figures 6 et 9) lorsqu'il est possible de relever l'organe de cadenassage 26 en saillie de la face avant du boîtier 11, position dans laquelle la manette 22 est bloquée en position ouvert.The assembly of the remote control unit 10 to the circuit breaker 12 (FIG. 1) is carried out when the trip bar 24 inside the housing 11 of the remote control unit is located opposite the trip bar of the circuit breaker 12. For safety reasons for mounting, the circuit breaker 12 must be in the open state, which implies a state agreement for the remote control unit 10. The remote control unit 10 is in the open state (FIGS. 6 and 9) when it is possible to raise the padlocking member 26 projecting from the front face of the housing 11, position in which the lever 22 is locked in the open position.

La barre de déclenchement 24 coopère avec un dispositif d'indexation 80 formé par un levier de polarisation 82 monté sur l'axe 31 et entraîné à pivotement par un organe d'attache 84 solidaire de l'organe de cadenassage 26. En position de saillie de l'organe de cadenassage 26, le levier de polarisation 82 est entraîné pour venir en engagement avec la barre de déclenchement 24 (figures 6 et 9) du bloc de télécommande 10, de manière à la positionner en concordance d'état avec le disjoncteur 12. Il est alors possible d'accoler et d'accoupler les deux blocs 10, 12 ainsi que les auxiliaires 14, 16, 18 de déclenchement et de commande.
Lors de l'enfoncement de l'organe de cadenassage 26 (figure 10), l'organe d'attache 84 repousse le levier de polarisation 82 vers une position inactive en appui d'une butée 86, autorisant la libération de la barre de déclenchement 24 à l'intérieur du boîtier 11. La barre de déclenchement 24 est alors en liaison mécanique avec le disjoncteur 12 et les auxiliaires 14, 16, 18, autorisant la transmission bidirectionnelle des informations ou ordres du disjoncteur 12 vers les auxiliaires 14, 16, 18, et réciproquement des auxiliaires vers le disjoncteur.The trigger bar 24 cooperates with an indexing device 80 formed by a polarization lever 82 mounted on the axis 31 and pivotally driven by a fastening member 84 secured to the padlocking member 26. In the projecting position of the padlocking member 26, the bias lever 82 is driven to engage with the trip bar 24 (Figures 6 and 9) of the remote control unit 10, so as to position it in accordance with the state of the circuit breaker 12. It is then possible to attach and couple the two blocks 10, 12 as well as the auxiliaries 14, 16, 18 for triggering and control.
When the lockout member 26 is pushed in (FIG. 10), the fastening member 84 pushes the bias lever 82 into an inactive position in support of a stop 86, authorizing the release of the trigger bar 24 inside the housing 11. The trip bar 24 is then in mechanical connection with the circuit breaker 12 and the auxiliaries 14, 16, 18, authorizing the bidirectional transmission of information or orders from the circuit breaker 12 to the auxiliaries 14, 16, 18, and vice versa of the auxiliaries to the circuit breaker.

En référence aux figures 11 et 12, chaque pignon du réducteur de vitesse 34 est monté sur un axe de fixation 88 emmanché à force dans un logement 90 d'une paroi du boîtier 11 en matériau thermoplastique. L'axe 88 cylindrique comporte une première partie d'ancrage 92 située près de la zone terminale, une deuxième partie intermédiaire 94 lisse, et une troisième partie de support 96 du pignon (non représenté).
La première partie d'ancrage 92 est dotée d'une succession de dents 98 s'étendant axialement sur une longueur E1. Chaque dent 98 est formée d'une portion tronconique D, et d'une portion cylindrique C de diamètre D1. La deuxième partie intermédiaire 94 possède le même diamètre D1, lequel est inférieur à celui de la troisième partie 96 constituant un palier pour le pignon. Le logement 90 du boîtier 11 est subdivisé en deux orifices 100, 102, coaxiaux ayant des diamètres D2 et D3 différents.With reference to FIGS. 11 and 12, each pinion of the speed reducer 34 is mounted on a fixing pin 88 force fitted into a housing 90 of a wall of the housing 11 made of thermoplastic material. The cylindrical axis 88 includes a first anchoring part 92 located near the end zone, a second intermediate smooth part 94, and a third support part 96 of the pinion (not shown).
The first anchoring part 92 is provided with a succession of teeth 98 extending axially over a length E1. Each tooth 98 is formed of a frustoconical portion D, and of a cylindrical portion C of diameter D1. The second intermediate part 94 has the same diameter D1, which is less than that of the third part 96 constituting a bearing for the pinion. The housing 90 of the housing 11 is subdivided into two orifices 100, 102, coaxial having diameters D2 and D3 different.

La longueur E1 de la première partie d'ancrage 92 est suffisante pour garantir un centrage axial de l'axe 88 lors de son introduction dans l'orifice supérieur 100.
Le diamètre D2 est légèrement supérieur à celui D1 de l'axe 88 de manière à autoriser un libre coulissement dans l'orifice 100 avec un ajustement glissant. Le mouvement d'enfoncement poursuivi de la partie d'ancrage 92 dans l'orifice inférieur 102 s'effectue avec un ajustement serré, avec formation d'un bourrelet de matière plastique entre chaque dent 98 interdisant l'arrachement de l'axe 88.
L'axe 88 en position encastrée constitue un palier en porte-à-faux pour le pignon, lequel est monté en rotation libre sur la troisième partie de support 96. Le précentrage axial de l'axe 88 est assuré avant l'incrustation des dents 98 dans la matière plastique au niveau de l'orifice 102. La longueur axiale H2 de l'orifice 102 détermine la course de précentrage, laquelle est identique à la longueur de la deuxième partie 94 intermédiaire de l'axe 88. La longueur axiale E1 de la première partie d'ancrage 92 de l'axe 88 est inférieure à la longueur H2, et correspond sensiblement à celle E2 de l'orifice inférieur 102. Un tel montage en porte-à-faux de l'axe 88 constitue un ancrage indémontable.The length E1 of the first anchoring part 92 is sufficient to guarantee an axial centering of the axis 88 during its introduction into the upper orifice 100.
The diameter D2 is slightly greater than that D1 of the axis 88 so as to allow free sliding in the orifice 100 with a sliding adjustment. The continued driving movement of the anchoring part 92 in the lower orifice 102 is carried out with a tight fit, with the formation of a bead of plastic material between each tooth 98 preventing the tearing of the pin 88.
The pin 88 in the embedded position constitutes a cantilever bearing for the pinion, which is mounted in free rotation on the third support part 96. The axial pre-centering of the pin 88 is ensured before the teeth are encrusted 98 in the plastic at the orifice 102. The axial length H2 of the orifice 102 determines the pre-centering stroke, which is identical to the length of the second intermediate portion 94 of the axis 88. The axial length E1 of the first anchoring part 92 of the axis 88 is less than the length H2, and corresponds substantially to that E2 of the lower orifice 102. Such a cantilever mounting of the axis 88 constitutes an anchoring cannot be dismantled.

Un voyant mécanique 110 (figure 5) indique l'état interne du mécanisme du dispositif de télécommande 10. Le voyant est monté sur un levier de commande 112 monté sur un axe 113 d'un pignon 114 du réducteur 34. Le levier 112 peut occuper une première position (voyant rouge) lorsque la télécommande est alimentée et une deuxième position (voyant gris) lorsque la télécommande n' est pas alimentée.A mechanical indicator 110 (FIG. 5) indicates the internal state of the mechanism of the remote control device 10. The indicator is mounted on a control lever 112 mounted on an axis 113 of a pinion 114 of the reduction gear 34. The lever 112 can occupy a first position (red light) when the remote control is powered and a second position (gray light) when the remote control is not powered.
