Mais d'autres avantages et caractéristiques de l'invention apparaítront mieux dans la description détaillée qui suit et se réfère aux dessins annexés donnés uniquement à titre d'exemple et dans lesquels :

  • La figure 1 est une vue partielle et en coupe illustrant une partie d'un disjoncteur comprenant les contacts, le mécanisme d'ouverture des contacts, la manette et le dispositif de signalisation d'un défaut, en position ouverte de l'appareil après une ouverture manuelle,

  • Les figures 5 et 6 sont des vues identiques respectivement aux figures 1 et 3, mais illustrant particulièrement le changement de profil de l'équipage mobile en fonction de la vitesse d'ouverture du mécanisme.
But other advantages and features of the invention will appear better in the detailed description which follows and refers to the accompanying drawings given solely by way of example and in which:
  • FIG. 1 is a partial sectional view illustrating a part of a circuit breaker comprising the contacts, the mechanism for opening the contacts, the handle and the device for signaling a fault, in the open position of the apparatus after a manual opening,
  • FIG. 2 is a view identical to the previous one, illustrating the apparatus in the closed position after a manual closure,

  • FIG. 4 is a view identical to the previous ones, illustrating the apparatus in the open position after unlocking on a fault, the handle having been brought back to the open position, and
  • Figures 5 and 6 are views respectively identical to Figures 1 and 3, but particularly illustrating the change of profile of the moving assembly as a function of the opening speed of the mechanism.

Sur les figures, on voit un dispositif d'ouverture des contacts fixe 1 et mobile 2 d'un disjoncteur D (représenté partiellement) logé dans un boítier isolant B. Ce contact mobile 2 peut être actionné manuellement par une manette 3 montée à pivotement entre une position de fermeture et une position d'ouverture des contacts 1,2, ladite manette 3 étant rappelée en position d'ouverture par un ressort de manette 4 et étant reliée à un dispositif de support 5 du contact mobile 2, ou platine, ladite platine 5 étant rappelée en position d'ouverture du contact 2 par un ressort 6. Ce contact mobile 2 peut également être actionné automatiquement par l'intermédiaire d'un mécanisme M comportant le dispositif de support 5 du contact mobile 2, lequel étant monté à rotation entre les deux positions précitées et étant relié à la manette 3 par un équipage mobile E de manière à former entre le dispositif 5 et la manette 3 une liaison mécanique brisable. Cette liaison mécanique comprend une biellette de transmission 7 articulée par l'une de ses extrémités sur la manette 3, et par son autre extrémité, sur un crochet 8 articulé sur la platine 5 et coopérant avec un moyen de déclenchement 9. Ce moyen de déclenchement 9 comprend un levier de déclenchement 10 commandé par un déclencheur T pour provoquer, en cas de défaut électrique, la rupture de la liaison mécanique entraínant le déclenchement automatique du mécanisme M et la séparation des contacts 1,2, indépendamment de la manette 3. Un moyen de rappel du moyen de déclenchement 9 vers une position armée, autorise le réarmement automatique du mécanisme lorsque la manette 3 est en position d'ouverture.In the figures, we see a device for opening the fixed contacts 1 and mobile 2 of a circuit-breaker D (shown partially) housed in an insulating housing B. This moving contact 2 can be manually operated by a handle 3 pivotally mounted between a position closure and an open position of the contacts 1,2, said lever 3 being recalled in opening position by a handle spring 4 and being connected to a support device 5 mobile contact 2, or platinum, said platen 5 being biased to the open position of the contact 2 by a spring 6. This movable contact 2 can also be actuated automatically via a mechanism M comprising the support device 5 of the movable contact 2, which is rotatably mounted between the two aforementioned positions and being connected to the handle 3 by a moving element E so as to form between the device 5 and the lever 3 a breakable mechanical connection. This mechanical connection comprises a transmission rod 7 articulated by one of its ends on the handle 3, and by its other end, on a hook 8 articulated on the plate 5 and cooperating with a means of trigger 9. This triggering means 9 comprises a trigger lever 10 controlled by a trigger T to cause, in the event of an electrical fault, the rupture of the mechanical connection that triggers the automatic triggering of the mechanism M and the separation of the contacts 1,2, independently of the joystick 3. A means for recalling the triggering means 9 to an armed position, allows automatic reset of the mechanism when the handle 3 is in the open position.

L'appareil comporte également un moyen de signalisation S de l'état déclenché du disjoncteur D. Ce moyen de signalisation S comprend un volet 11 monté coulissant en translation dans la paroi supérieure du boítier B du disjoncteur D et coopérant avec une ouverture O prévue dans le boítier B. Ce volet 11 est destiné à coopérer avec une patte 12 solidaire du crochet précité 8 et avec un talon 13 appartenant à la platine 5 d'une manière qui va être décrite dans ce qui suit.The apparatus also comprises a signaling means S of the triggered state of circuit breaker D. This signaling means S comprises a shutter 11 slidably mounted in translation into the upper wall of the housing B of the circuit breaker D and cooperating with a O opening provided in the housing B. This flap 11 is intended to cooperate with a leg 12 secured to the aforementioned hook 8 and with a heel 13 belonging to the plate 5 in a manner which will be described in the following.

Le fonctionnement du dispositif de signalisation de défaut S selon l'invention va être décrit dans ce qui suit en référence aux figures.The operation of the fault signaling device S according to the invention will be described in the following with reference to the figures.

Sur la figure 1, l'appareil D est en position ouverte, les contacts fixe 1 et mobile 2 étant séparés suite à une ouverture manuelle. Lors de cette manoeuvre, la rotation de la manette 3 a entraíné la rotation de la platine 5 dans le sens anti-horaire. Le crochet 8 n'a pratiquement pas changé de position par rapport à la platine 5. La configuration du crochet 8 et de la barre 10, ou levier, sont telles qu'aucun contact ne s'est établi entre la patte 12 du crochet 8 et le volet 11, lequel reste dans une position dite haute indiquant qu'aucun déclenchement suite à un défaut ne s'est produit. Le profil de l'équipage mobile E dans cette position est représenté sur la figure 5.In FIG. 1, the apparatus D is in the open position, the fixed and movable contacts 1 and 2 being separated by manual opening. During this maneuver, the rotation of the joystick 3 has led the rotation of the plate 5 in the counterclockwise direction. The hook 8 practically does not no change of position with respect to the plate 5. The configuration of the hook 8 and the bar 10, or lever, are such that no contact has been established between the tab 12 of the hook 8 and the flap 11, which remains in a so-called high position indicating that no triggering following a fault has occurred. The profile of the mobile equipment E in this position is shown in Figure 5.

Sur la figure 2, une manoeuvre de fermeture manuelle a eu lieu ayant entraíné la rotation de la platine 5 dans le sens horaire jusqu'à ce que les contacts 1,2 soient dans une position fermée.In FIG. 2, a manual closing maneuver has taken place which has led to the rotation of the plate 5 clockwise until the contacts 1,2 are in a position closed.

Dans cette position fermée des contacts 1,2, le talon 13 est en appui contre une partie en saillie 11a du volet 11, ladite partie en saillie s'étendant perpendiculairement à la direction longitudinale du volet 11, de façon à polariser ce volet 11 dans une direction opposée à la manette 3.In this closed position of the contacts 1,2, the heel 13 bears against a part projection 11a of the flap 11, said protruding portion extending perpendicular to the direction longitudinally of the flap 11, so as to polarize the flap 11 in a direction opposite to the joystick 3.

Sur la figure 3, une ouverture automatique par déverrouillage a eu lieu suite à l'apparition d'un défaut électrique. Lors de l'apparition d'un défaut électrique, le déclencheur T entraíne en rotation la barre de déclenchement 10, ce qui libère le crochet 8 de son engagement avec la barre de déclenchement 10. Le crochet 8 ainsi libéré, la platine 5 peut être entraínée en rotation dans le sens de l'ouverture des contacts 1,2, étant rappelée dans cette position par le ressort de rappel 6. Or, la vitesse de chaque élément est fonction de son inertie et de la force du ressort de rappel de cet élément. L'inertie du crochet 8 est inférieure à celle de la manette et la force de rappel du ressort de rappel 6 de la platine 5 est réglée de manière à être supérieure à la force de rappel du ressort 4 de la manette 3. En conséquence, la vitesse de rotation du crochet 8 est supérieure à la vitesse de rotation de la poignée 3. De ce fait, la libération de la platine 5 en rotation entraíne le crochet 8 dans un rapide mouvement de rotation. Pendant ce mouvement, la patte 12 du crochet 8 entraíne le volet 11 en translation vers une position illustrée sur la figure 3, dans laquelle le volet 11 se trouve en regard de l'ouverture O du boítier B, position du volet 11 indiquant une ouverture par déverrouillage du mécanisme M. Le profil de l'équipage mobile E dans cette position est représenté sur la figure 6. Pendant ce temps, la poignée 3 retardée par sa forte inertie et la faible force de rappel de son ressort de rappel 4 est restée pratiquement immobile. Puis, la poignée 3 est rappelée lentement en position ouverte illustrée sur la figure 4. Pendant ce mouvement, le crochet 8 est entraíné en rotation dans le sens des aiguilles d'une montre et le volet 11 reste en position basse telle qu'illustrée sur la figure 4, pour signaler une ouverture par défaut du mécanisme. Lors d'une fermeture manuelle ultérieure, le talon 13 de la platine 5 entraínera de nouveau le volet 11 en position haute telle qu'illustrée sur la figure 2.In FIG. 3, an automatic opening by unlocking has taken place following the appearance an electrical fault. When an electrical fault occurs, the trigger T causes in rotation the trigger bar 10, which releases the hook 8 from its engagement with the trigger bar 10. The hook 8 thus released, the plate 5 can be driven in rotation in the direction of the opening of the contacts 1,2, being recalled in this position by the return spring 6. However, the speed of each element is a function of its inertia and the spring force of this element. The inertia of the hook 8 is less than that of the handle and the restoring force of the return spring 6 of the plate 5 is set to be greater than the return force of the spring 4 of the joystick 3. As a result, the speed the rotation of the hook 8 is greater than the speed of rotation of the handle 3. As a result, the release of the rotating plate 5 causes the hook 8 in a rapid movement of rotation. During this movement, the tab 12 of the hook 8 drives the shutter 11 in translation to a position illustrated in Figure 3, in which the flap 11 is next to the opening O of the housing B, position of the flap 11 indicating an opening by unlocking of the mechanism M. The profile of the moving element E in this position is represented on the Figure 6. Meanwhile, the handle 3 delayed by its high inertia and the low force of recall of its return spring 4 remained virtually immobile. Then, the handle 3 is recalled slowly in the open position shown in Figure 4. During this movement, the hook 8 is rotated in the direction of clockwise and the flap 11 remains in the down position as shown in Figure 4, to signal a default opening of the mechanism. During a subsequent manual closing, the heel 13 of the plate 5 will result in again the flap 11 in the high position as illustrated in Figure 2.

On a donc réalisé grâce à l'invention, un dispositif de signalisation de l'ouverture d'un appareil, par exemple un disjoncteur, uniquement si cette ouverture est occasionnée par le déverrouillage de son mécanisme M à l'occasion d'un défaut de type surcharge, court-circuit, ou lorsque l'ordre d'un auxiliaire adapté est envoyé, ce dispositif de signalisation étant intégré au produit. Il n'est alors plus nécessaire de recourir à un accessoire supplémentaire et la prise d'informations est réalisée au niveau d'un seul élément, le crochet, d'où une simplification de la conception de l'appareil comportant cette fonction de signalisation.It has therefore been realized thanks to the invention, a device for signaling the opening of a device, for example a circuit-breaker, only if this opening is caused by the unlocking its mechanism M during a fault of the overload, short-circuit type, or when the order of a suitable auxiliary is sent, this signaling device being built into the product. It is no longer necessary to use an accessory additional information and the taking of information is carried out at the level of a single element, the a simplification of the design of the apparatus comprising this function of signaling.

Le système de signalisation d'état de mécanisme selon l'invention est lié à sa séquence de fonctionnement. L'identification de la séquence de fonctionnement est réalisée grâce aux vitesses différentielles des éléments, lesdites vitesses étant déterminées par l'inertie desdits éléments et les forces de rappel de leur ressort. The mechanism state signaling system according to the invention is related to its sequence of operation. The identification of the sequence of operation is carried out thanks to differential speeds of the elements, said speeds being determined by the inertia of said elements and the return forces of their spring.

On notera également que la mémorisation de séquence peut être effacée soit automatiquement par une manoeuvre de fermeture de la poignée ou par un autre organe distinct.It should also be noted that the sequence memory can be erased either automatically by closing the handle or by another body separate.

En plus de la fonction signalisation défaut décrite précédemment le voyant peut également assurer la fonction classique de signalisation Ouvert / Fermé en ajoutant une troisième position intermédiaire au voyant 11 et un deuxième talon en regard du 13 sur la platine 5.In addition to the fault signaling function previously described, the LED can also be provide the classic open / closed signaling function by adding a third intermediate position to the indicator 11 and a second heel facing the 13 on the plate 5.

L'invention s'applique à tout appareil tel un disjoncteur ou un interrupteur différentiel et de façon générale à tout appareil assurant un déclenchement par un autre moyen que par une ouverture manuelle.The invention applies to any device such as a circuit breaker or a differential switch and generally to any device which provides a trigger by any means other than manual opening.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple.Of course, the invention is not limited to the described and illustrated embodiments which have been given only as an example.

Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit.On the contrary, the invention includes all the technical equivalents of the means thus described. that their combinations if they are carried out according to his spirit.
