Description

La présente invention concerne le domaine des installations électriques, en particulier de la protection des différents circuits contre les surcharges telles que les courts-circuits et les contacts directs ou indirects, au moyen d'appareillages électriques de sécurité tels que des disjoncteurs, des disjoncteurs différentiels ou des interrupteurs différentiels, notamment des dispositifs de commande à distance de tels appareillages, et pour objet un dispositif de commande à distance pour appareillage modulaire de protection.The present invention relates to the field of installations electrical, in particular the protection of the various circuits against overloads such as short circuits and direct or indirect contacts, by means of electrical safety devices such as circuit breakers, earth leakage breakers or earth leakage switches, in particular remote control devices for such devices, and for their purpose a remote control device for modular switchgear protection.

Pour certains de ces circuits, la mise hors tension à la suite d'un défaut peut occasionner une gêne importante pour l'utilisateur, par exemple dans le cas d'un circuit alimentant une installation de congélation, de chauffage, des appareils de protection incendie ou encore lorsqu'un appareil commandé est situé dans un local non surveillé, par exemple dans une installation industrielle.For some of these circuits, switching off after a fault can cause significant inconvenience to the user, for example in the case of a circuit supplying a freezing installation, heating, fire protection devices or even when a device ordered is located in an unsupervised room, for example in a industrial installation.

Le déclenchement d'un appareil de protection n'a pas toujours pour origine un défaut franc et permanent. En effet, un tel déclenchement peut provenir de défauts transitoires qui disparaissent d'eux-même, par exemple d'une onde de courant ou de tension transitoire due à un coup de foudre sur la ligne de transport de courant, une condensation générant une humidité importante susceptible de provoquer une fuite à la terre et qui disparaít après séchage, etc...The triggering of a protective device did not always for origin a frank and permanent defect. Indeed, such a trigger may arise from transient faults that disappear on their own, for example example of a current wave or transient voltage due to a blow of lightning on the current transmission line, condensation generating a high humidity which may cause earth leakage and which disappears after drying, etc ...

Dans de tels cas, il existe des dispositifs de réarmement automatique effectuant un ou plusieurs essais de ré enclenchement successifs à des intervalles de temps de plus en plus longs. De tels dispositifs servent principalement dans des installations urbaines de type candélabres, abris publics, enseignes lumineuses, etc...In such cases, there are reset devices automatic performing one or more reset attempts successive at increasingly longer time intervals. Such devices are mainly used in urban type installations candelabras, public shelters, illuminated signs, etc.

La conception de ces appareillages électriques de sécurité fait souvent intervenir l'électronique pour la fonction différentielle. En outre, ces appareillages sont la plupart du temps équipés de moyens de contact simples ne tolérant que des courants nominaux relativement faibles et ont des performances en court-circuit limitées.The design of these electrical safety devices makes electronics often intervene for the differential function. In addition, these devices are mostly equipped with contact means simple tolerant only relatively small nominal currents and have limited short circuit performance.

Il s'ensuit un problème de répétition du ré enclenchement ou réarmement de ces appareillages et de la surcharge au niveau des moyens de contact, dont la pérennité peut gravement être remise en cause. Il convient donc de réaliser un ré enclenchement ou un réarmement rapide de ces appareillages, permettant d'éviter la dégradation prématurée des moyens de contact.It follows a problem of repetition of the re-engagement or resetting of these devices and overload in terms of means contact, the sustainability of which can be seriously called into question. he therefore it is advisable to carry out a fast reclosing or rearming of these devices, avoiding premature degradation of resources of contact.

Les dispositifs de réarmement automatique connus à ce jour sont généralement sous forme de motoréducteurs coopérant, par l'intermédiaire d'éléments de liaison linéaires, avec les moyens d'actionnement des appareillages. Ces dispositifs permettent, certes, une commande fiable du réarmement, mais leur mode opératoire, qui fait intervenir un moyen de commande rotatif associé à un dispositif de transformation de mouvement à réducteur ou analogue, met en oeuvre une vitesse de réarmement relativement faible, qui est préjudiciable pour la pérennité des contacts. En outre, ces dispositifs sont d'un prix de revient élevé.Automatic reset devices known to date are generally in the form of cooperating geared motors, by through linear connecting elements, with the means actuation of equipment. These devices certainly allow reliable reset command, but their mode of operation, which makes intervene a rotary control means associated with a transformation of movement with reduction gear or the like, implements a relatively low reset speed, which is detrimental to the sustainability of contacts. In addition, these devices are cost Student.

La présente invention a pour but de pallier ces inconvénients en proposant un dispositif de commande à distance pour appareillage modulaire de protection permettant, d'une part, de commander une gamme de produits très large du point de vue courant nominaux admissibles et performance, d'autre part, de réaliser un ré enclenchement ou un réarmement suffisamment rapide pour éviter tout risque d'endommagement des contacts et, enfin, d'effectuer un déclenchement commandé à distance.The object of the present invention is to overcome these drawbacks by proposing a remote control device for switchgear modular protection allowing, on the one hand, to control a range of products very broad from the current standpoint nominal admissible and performance, on the other hand, to achieve a re-engagement or a resetting fast enough to avoid any risk of damage contacts and, finally, to carry out a triggering controlled remotely.

A cet effet, le dispositif de commande à distance pour appareillage modulaire de protection, en particulier pour enclencher ou déclencher à distance, au moyen d'un interrupteur à bouton-poussoir, d'un interrupteur horaire, d'un contacteur ou autre, un appareillage de protection modulaire, tel qu'un disjoncteur-interrupteur différentiel ou un disjoncteur différentiel, est caractérisé en ce qu'il est essentiellement constitué par un premier moyen d'actionnement, à mouvement linéaire, en ré enclenchement de l'appareillage modulaire à commander, par un deuxième moyen d'actionnement, également à mouvement linéaire, de déclenchement dudit appareillage modulaire à commander et par un circuit électronique de commande des premier et deuxième moyens d'actionnement.To this end, the remote control device for modular protective equipment, in particular for interlocking or remotely trigger, by means of a push-button switch, a time switch, contactor or other, protective equipment modular, such as a differential circuit breaker or a circuit breaker differential, is characterized in that it is essentially constituted by a first actuation means, linear movement, in reclosing of the modular apparatus to be controlled, by a second means actuation, also with linear movement, for triggering said modular equipment to be controlled and by an electronic circuit control of the first and second actuation means.

    • Les figures 1 à 7 et 9 à 11 des dessins annexés représentent un dispositif de commande à distance pour appareillage modulaire de protection 1, en particulier pour enclencher ou déclencher à distance, au moyen d'un interrupteur à bouton-poussoir, d'un interrupteur horaire, d'un contacteur ou autre, un appareillage de protection modulaire, tel qu'un disjoncteur-interrupteur différentiel ou un disjoncteur différentiel, qui est relié mécaniquement à une face latérale dudit appareillage 1 et qui se présente sous forme d'un boítier 2 de contour général correspondant à celui de l'appareillage modulaire 1 à commander. Figures 1 to 7 and 9 to 11 of the accompanying drawings show a remote control device for modular switchgear protection 1, in particular for switching on or off remotely, by means of a push button switch, a time switch, a contactor or other, modular protective equipment, such as a earth leakage circuit breaker or a earth leakage circuit breaker, which is mechanically connected to a lateral face of said apparatus 1 and which is present in the form of a box 2 of general outline corresponding to that of modular equipment 1 to be ordered.

    Conformément à l'invention, ce dispositif de commande est essentiellement constitué par un premier moyen d'actionnement 3, à mouvement linéaire, en ré enclenchement de l'appareillage modulaire à commander 1, par un deuxième moyen d'actionnement 4, également à mouvement linéaire, de déclenchement dudit appareillage modulaire à commander 1 et par un circuit électronique 5 de commande des premier et deuxième moyens 3 et 4 d'actionnement.According to the invention, this control device is essentially constituted by a first actuating means 3, to linear movement, in reclosing of the modular equipment with command 1, by a second actuating means 4, also at linear movement, triggering of said modular apparatus at control 1 and by an electronic circuit 5 for controlling the first and second means 3 and 4 for actuation.

    Selon un premier mode de réalisation représenté aux figures 1 à 6 et 9 des dessins annexés, le premier moyen 3 d'actionnement, à mouvement linéaire, en ré enclenchement de l'appareillage modulaire à commander 1 est constitué par un électro-aimant 6 relié à un levier d'enclenchement 7, à mouvement pivotant autour d'un axe 7', destiné à coopérer, par l'intermédiaire d'un doigt d'entraínement 7", avec une manette 8 de l'appareillage modulaire à commander 1. La liaison entre l'électro-aimant 6 et le levier d'enclenchement 7 est effectuée au moyen du noyau mobile 6' de l'électro-aimant 6 qui coopère, par un axe 9, à son extrémité opposée au corps de l'électro-aimant 6 avec une rainure 7''' du levier d'enclenchement 7. Pour améliorer le guidage de l'axe 9 dans la rainure 7"' du levier d'enclenchement 7, ledit axe 9 est avantageusement muni de patins de guidage 10 montés à coulissement dans ladite rainure 7''' du levier d'enclenchement 7.According to a first embodiment shown in Figures 1 to 6 and 9 of the accompanying drawings, the first actuation means 3, to linear movement, in reclosing of the modular equipment with command 1 is constituted by an electromagnet 6 connected to a lever latching 7, with movement pivoting about an axis 7 ', intended to cooperate, via a drive finger 7 ", with a lever 8 of the modular equipment to be controlled 1. The connection between the electromagnet 6 and the engagement lever 7 is effected by means of the core mobile 6 'of the electromagnet 6 which cooperates, by an axis 9, at its end opposite the body of the electromagnet 6 with a groove 7 '' 'of the lever 7. To improve the guiding of the axis 9 in the groove 7 "' of the engagement lever 7, said axis 9 is advantageously provided with pads guide 10 slidably mounted in said groove 7 '' 'of the lever 7.

    Ainsi, lors d'un déplacement du noyau mobile 6' dans le corps de l'électro-aimant 6, le levier d'enclenchement 7 est entraíné dans un mouvement de pivotement autour de son axe 7', de sorte que le doigt d'entraínement 7" subit également un mouvement de pivotement. Ce mouvement de pivotement du levier 7, qui traduit, en fait, une transformation du mouvement linéaire du noyau mobile 6' en un mouvement partiel de rotation du doigt d'entraínement 7", est rendu possible par la liaison à coulissement entre le levier d'enclenchement 7 et l'extrémité correspondante du noyau 6' de l'électro-aimant 6, grâce à la rainure 7"' dudit levier d'enclenchement 7 (figures 1 et 3).Thus, during a displacement of the mobile core 6 'in the body of the electromagnet 6, the latching lever 7 is driven in a pivoting movement around its axis 7 ', so that the finger drive 7 "also undergoes a pivoting movement. pivoting movement of the lever 7, which translates, in fact, a transformation of the linear movement of the mobile core 6 'into one partial movement of rotation of the driving finger 7 ", is rendered possible by sliding connection between the engagement lever 7 and the corresponding end of the core 6 ′ of the electromagnet 6, thanks to the groove 7 "'of said engagement lever 7 (Figures 1 and 3).

    De préférence, le noyau mobile 6' de l'électro-aimant 6 est chargé par un ressort 11 le maintenant dans une position normalement sortie au repos (figures 1 à 3). Un tel mode de réalisation permet, d'une part, un positionnement du levier 7 et donc du doigt d'entraínement 7", dans lequel ce dernier est placé sous la manette 8 de ré enclenchement de l'appareillage à commander 1 (figure 8) et, d'autre part, un actionnement très rapide du noyau mobile 6' et son retour immédiat en position de repos lors d'une simple impulsion sur la bobine de l'électro-aimant 6. Une position de ré enclenchement obtenue suite à une telle impulsion est représentée plus particulièrement à la figure 3 des dessins annexés.Preferably, the movable core 6 'of the electromagnet 6 is loaded by a spring 11 keeping it in a normally extended position at rest (Figures 1 to 3). Such an embodiment allows, on the one hand, a positioning of the lever 7 and therefore of the drive finger 7 ", in which the latter is placed under the switch 8 for resetting the apparatus to be controlled 1 (FIG. 8) and, on the other hand, very rapid actuation of the mobile core 6 'and its immediate return to the rest position during a single pulse on the solenoid coil 6. A re position engagement obtained following such an impulse is shown more particularly in Figure 3 of the accompanying drawings.

    Comme il ressort plus particulièrement de la figure 7 des dessins annexés, le doigt d'entraínement 7" du levier d'enclenchement 7 traverse une rainure curviligne 2' de la face latérale du boítier 2 tournée vers l'appareillage à commander 1. Ainsi, comme le montre la figure 8, dans la position de repos du dispositif, le doigt d'entraínement 7" est situé contre la face avant du boítier de l'appareillage à commander 1 dans une position telle qu'il soit sous la manette 8 de ré enclenchement dudit appareillage 1 après un déclenchement de ce dernier.As appears more particularly from FIG. 7 of attached drawings, the driving finger 7 "of the engagement lever 7 crosses a curvilinear groove 2 ′ on the side face of the housing 2 facing the apparatus to be controlled 1. Thus, as shown in FIG. 8, in the device rest position, the drive finger 7 "is located against the front face of the switchgear unit 1 in a position as it is under the lever 8 for re-engagement of said apparatus 1 after a trigger of the latter.

    Le deuxième moyen d'actionnement 4, à mouvement linéaire, de déclenchement de l'appareillage modulaire à commander 1 est constitué par un électro-aimant 12, dont le noyau mobile 12' coopère avec un levier de déclenchement 13, guidé en pivotement dans le boítier 2, pourvu d'un doigt d'entraínement 13' traversant la face latérale du boítier 2 tournée vers l'appareillage à commander 1 et coopérant avec la serrure 14 de ce dernier (figure 4), à travers une ouverture correspondante 14' (figures 1 à 5 et 7), ce levier 13 étant, en outre, chargé par un ressort 13" de rappel en position de repos.The second actuation means 4, with linear movement, for triggering the modular equipment to be controlled 1 consists of by an electromagnet 12, the movable core 12 'of which cooperates with a lever trigger 13, pivotally guided in the housing 2, provided with a drive finger 13 'passing through the side face of the housing 2 facing towards the apparatus to be controlled 1 and cooperating with the lock 14 of the latter (Figure 4), through a corresponding opening 14 '(Figures 1 to 5 and 7), this lever 13 being, in addition, loaded by a spring 13 "returning to the position of rest.

    Ce deuxième moyen d'actionnement 4 est destiné à réaliser un déclenchement volontaire de l'appareillage 1 à commander à distance. A cet effet, il suffit de délivrer une impulsion de commande à l'électro-aimant 12, afin de déplacer le noyau 12' contre le levier de déclenchement 13 et de faire pivoter ce dernier de manière à entraíner par le doigt d'entraínement 13' la pièce de déverrouillage de la serrure 14 dudit appareillage à commander 1.This second actuation means 4 is intended to produce a voluntary activation of device 1 to be controlled remotely. In this indeed, it suffices to deliver a control pulse to the electromagnet 12, in order to move the core 12 ′ against the trigger lever 13 and to rotate the latter so as to drive by the training finger 13 'the unlocking part of the lock 14 of said apparatus to order 1.

    Le circuit électronique 5 de commande des premier et deuxième moyens 3 et 4 d'actionnement est avantageusement sous forme d'une carte électronique reliée aux bornes des électro-aimants 6 et 12 respectifs et est pourvu d'une temporisation des impulsions de commande délivrées à ces électro-aimants. La temporisation est avantageusement réglable de manière à déterminer une durée d'impulsion très limitée, afin d'éviter la destruction des bobines des électro-aimants 6 ou 12 par échauffement. De préférence, la durée des impulsions de commande des électro-aimants 6 et 12 est réglée à des valeurs de l'ordre de quelques millisecondes, ce qui est suffisant pour assurer l'attraction des noyaux mobiles 6' et 12'.The electronic circuit 5 for controlling the first and second actuation means 3 and 4 is advantageously in the form an electronic card connected to the terminals of the electromagnets 6 and 12 respective and is provided with a timing of the control pulses delivered to these electromagnets. The time delay is advantageously adjustable so as to determine a very limited pulse duration, so to avoid the destruction of the coils of the electromagnets 6 or 12 by warming up. Preferably, the duration of the control pulses of the solenoids 6 and 12 are set to values on the order of a few milliseconds, which is enough to attract the nuclei mobile 6 'and 12'.

    Lors de la coupure de l'impulsion de commande de l'un ou l'autre des électro-aimants 6 ou 12, le noyau mobile correspondant 6' ou 12' est immédiatement ramené en position de départ, soit par l'intermédiaire du ressort de rappel 11, soit par le ressort de rappel 13" agissant sur le levier de déclenchement 13 coopérant avec la pièce de déverrouillage de la serrure 14.When switching off the command pulse from one or the other of the electromagnets 6 or 12, the corresponding movable core 6 'or 12' is immediately returned to the starting position, either through the return spring 11, either by return spring 13 "acting on the lever trigger 13 cooperating with the unlocking part of the lock 14.

    Selon une autre caractéristique de l'invention, le dispositif de commande est pourvu, en outre, d'un moyen de condamnation 15 empêchant, en position de service, toute mise en oeuvre de la commande à distance et des premier et deuxième moyens 3 et 4 d'actionnement respectivement en ré enclenchement et en déclenchement (figures 2 et 5 à 12).According to another characteristic of the invention, the device for control is further provided with a locking means 15 preventing, in the service position, any implementation of the command to distance and first and second actuation means 3 and 4 resetting and tripping respectively (Figures 2 and 5 to 12).

    Selon un premier mode de réalisation, ce moyen de condamnation 15 est constitué par un levier pivotant monté sur l'axe de pivotement 7' du levier d'enclenchement 7, ce levier pivotant 15 étant pourvu, d'une part, d'au moins un perçage 15', accessible en position de condamnation et destiné à coopérer, dans cette position de condamnation, avec un dispositif de verrouillage tel qu'un cadenas ou un fil de plombage (figures 2, 5, 6 et 9) et, d'autre part, d'une came 15" destinée à coopérer avec un contact électrique 16 de commande de l'alimentation du circuit électronique 5 de commande des premier et deuxième moyens 3 et 4 d'actionnement (figures 2, 5, 6 et 9). Le levier pivotant 15 est avantageusement pourvu de perçages 15' de diamètres différents permettant une adaptation au moyen de verrouillage choisi, à savoir cadenas ou fil de plombage.According to a first embodiment, this means of lock 15 is constituted by a pivoting lever mounted on the axis of pivoting 7 'of the engagement lever 7, this pivoting lever 15 being provided, on the one hand, with at least one bore 15 ', accessible in the position of condemnation and intended to cooperate, in this condemnation position, with a locking device such as a padlock or a sealing wire (Figures 2, 5, 6 and 9) and, on the other hand, a 15 "cam intended to cooperate with an electrical contact 16 for controlling the supply of the circuit electronic 5 for controlling the first and second means 3 and 4 actuation (Figures 2, 5, 6 and 9). The pivoting lever 15 is advantageously provided with holes 15 'of different diameters allowing an adaptation to the chosen locking means, namely padlock or wire filling.

    Ainsi, il est possible d'empêcher l'enclenchement de l'appareillage à commander 1 par condamnation de la télécommande réalisée au moyen du circuit électronique 5. Une telle condamnation peut être nécessaire lorsqu'un opérateur mène une intervention sur le circuit correspondant à l'appareillage à commander 1 et où, pour des raisons de sécurité, il faut maintenir la partie aval dudit circuit électrique ouverte.Thus, it is possible to prevent the engagement of switchgear to be controlled 1 by locking the remote control carried out by means of the electronic circuit 5. Such a condemnation can be necessary when an operator carries out an intervention on the circuit corresponding to the equipment to be ordered 1 and where, for reasons of safety, keep the downstream part of said electrical circuit open.

    La condamnation est réalisée en faisant pivoter vers l'extérieur de l'enveloppe le levier pivotant formant le moyen de condamnation 15. Il en résulte qu'un perçage 15' devient accessible et permet le passage d'un cadenas à clé ou d'un fil de plombage. Locking is carried out by pivoting outwards of the envelope the pivoting lever forming the locking means 15. It as a result, a hole 15 'becomes accessible and allows the passage of a padlock with key or a sealing wire.

    En outre, la rotation de ce levier 15 amène la came 15" en contact avec le contact électrique de commande 16 et réalise la coupure de l'alimentation du circuit électronique 5, de sorte que le fonctionnement du dispositif est empêché aussi bien à l'enclenchement qu'au déclenchement.In addition, the rotation of this lever 15 brings the cam 15 "into contact with the electrical control contact 16 and cuts off the electronic circuit 5, so that the operation of the device is prevented both when switching on and off.

    Par ailleurs, selon une autre caractéristique de l'invention, le levier 15 pivotant formant le moyen de condamnation est pourvu d'un élément en saillie 15"' destiné à l'actionnement du levier 13 de déclenchement coopérant avec la pièce de déverrouillage de la serrure 14 de l'appareillage à commander 1. Lors d'un pivotement du levier 15 dans la position de condamnation, cet élément 15"' entre en contact avec l'extrémité du levier de déclenchement 13 portant le doigt d'entraínement 13' et déplace ledit levier dans sa position de déclenchement, de sorte que le circuit en aval de l'appareillage à commander 1 est ouvert. Le fonctionnement de l'élément en saillie 15"' ressort plus particulièrement de la figure 9 des dessins annexés.Furthermore, according to another characteristic of the invention, the pivoting lever 15 forming the locking means is provided with a projecting element 15 "'for actuating the lever 13 of trigger cooperating with the unlocking part of the lock 14 of the apparatus to be controlled 1. When the lever 15 is pivoted in the locking position, this 15 "element comes into contact with the end trigger lever 13 carrying the drive finger 13 'and moves said lever in its release position, so that the circuit in downstream of the apparatus to be controlled 1 is open. The functioning of the projecting element 15 "'is shown more particularly in FIG. 9 of attached drawings.

    Les figures 10 à 14 des dessins annexés représentent une variante de réalisation de l'invention, dans laquelle le premier moyen d'actionnement 3 est constitué par un électro-aimant 6, dont le corps est monté de manière pivotable dans le boítier 2 par l'intermédiaire de supports 17 guidés en rotation dans le boítier 2 et dont le noyau mobile 6' est relié par son extrémité libre à un bras 18' d'un levier d'enclenchement 18 pivotant autour d'un axe 18" et pourvu d'un doigt d'entraínement 18"' destiné à coopérer avec la manette 8 de ré enclenchement de l'appareillage à commander 1.Figures 10 to 14 of the accompanying drawings show a variant embodiment of the invention, in which the first means actuator 3 consists of an electromagnet 6, the body of which is pivotally mounted in the housing 2 by means of supports 17 guided in rotation in the housing 2 and whose movable core 6 'is connected by its free end to an arm 18 ′ of a pivoting engagement lever 18 around an axis 18 "and provided with a drive finger 18" intended for cooperate with the handle 8 for resetting the apparatus to order 1.

    Selon une caractéristique de l'invention, l'axe 18' du levier d'enclenchement pivotant 18 est chargé par un ressort spiral 19 s'appuyant par son extrémité libre sur le corps de l'électroaimant 6 ou sur le support 17 correspondant. Ainsi, lors d'une impulsion de mise sous tension de l'électro-aimant 6, le noyau mobile 6' est attiré dans le corps dudit électro-aimant et entraíne en rotation le levier d'enclenchement 18 contre la force du ressort 19. Dès interruption de l'impulsion électrique sur l'électro-aimant 6, le ressort spiral 19 provoque une rotation du levier d'enclenchement 18 en sens inverse de celle induite par l'action du noyau mobile 6' et provoque le retour en position de départ dudit noyau 6' et du levier d'enclenchement pivotant 18. Le déplacement angulaire du corps 6 de l'électro-aimant et du noyau 6' relativement à leur axe longitudinal, lors de la rotation du levier d'enclenchement 18 est compensé par la possibilité de pivotement dudit corps de l'électro-aimant 6 procurée par les supports 17 qui sont guidés en rotation dans le boítier 2.According to a characteristic of the invention, the axis 18 'of the lever pivoting engagement 18 is loaded by a spiral spring 19 bearing by its free end on the body of the electromagnet 6 or on the support 17 corresponding. Thus, during a pulse to energize the electromagnet 6, the movable core 6 ′ is drawn into the body of said electromagnet and rotates the engagement lever 18 against the force of the spring 19. As soon as the electric pulse on the electromagnet 6 is interrupted, the spiral spring 19 causes rotation of the engagement lever 18 in opposite direction to that induced by the action of the mobile core 6 'and causes the return to the starting position of said core 6 ′ and of the latching lever pivoting 18. The angular displacement of the body 6 of the electromagnet and of the core 6 'relative to their longitudinal axis, when the lever rotates engagement 18 is compensated by the possibility of pivoting of said body of the electromagnet 6 provided by the supports 17 which are guided in rotation in the housing 2.

    Le deuxième moyen d'actionnement 4, de déclenchement de l'appareillage modulaire à commander 1 agit sur un levier de déclenchement 20 muni d'un doigt d'entraínement 20', par l'intermédiaire d'un levier amplificateur 21. Ainsi, la course du noyau mobile 12' de l'électro-aimant 12 constituant ce deuxième moyen d'actionnement 4 est amplifiée, de manière à garantir le déplacement correspondant de la pièce de liaison de la serrure de l'appareillage à commander 1.The second actuation means 4, for triggering the modular switchgear to be controlled 1 acts on a release lever 20 provided with a drive finger 20 ', by means of a lever amplifier 21. Thus, the stroke of the movable core 12 'of the electromagnet 12 constituting this second actuating means 4 is amplified, from so as to guarantee the corresponding displacement of the connecting piece of the switchgear lock 1.

    Selon une autre caractéristique de l'invention, le dispositif suivant les figures 10 à 14 est équipé d'un verrou de condamnation 22 guidé à coulissement dans la face avant du boítier 2 et pourvu, d'une part, d'au moins un perçage 22', accessible en position de condamnation et destiné à coopérer, dans cette position de condamnation, avec un dispositif de verrouillage tel qu'un cadenas ou un fil de plombage et, d'autre part, d'une came 22" destinée à coopérer avec un contact électrique 16 de commande de l'alimentation du circuit électronique 5 de commande des premier et deuxième moyens 3 et 4 d'actionnement.According to another characteristic of the invention, the device according to Figures 10 to 14 is fitted with a guided locking latch 22 sliding in the front face of the housing 2 and provided, on the one hand, with minus a bore 22 ', accessible in the locked position and intended for cooperate, in this locked position, with a device for locking such as a padlock or a sealing wire and, on the other hand, a 22 "cam intended to cooperate with an electrical control contact 16 supply of the electronic circuit 5 for controlling the first and second means 3 and 4 for actuation.

    Par ailleurs, ce verrou de condamnation 22 est muni d'un ergot 23 d'actionnement du levier de déclenchement 20. Cet ergot 23 entraíne ainsi, lors d'une extraction du verrou 22 hors de la face avant du boítier 2 pour libérer l'accès au perçage 22', le levier de déclenchement 20 dans un mouvement de pivotement dans lequel son doigt d'entraínement 20' actionne la serrure de l'appareillage à commander 1, dans le sens d'un déclenchement, de sorte que le circuit électrique en aval de cet appareillage 1 est mis hors tension. Ce mouvement d'extraction du verrou 22 amène simultanément la came 22" devant le contact électrique 16 et réalise la coupure du circuit électronique 5 et donc des électro-aimants 6 et 12.Furthermore, this locking bolt 22 is provided with a lug 23 actuation of the trigger lever 20. This lug 23 drives thus, during an extraction of the lock 22 out of the front face of the case 2 to free access to the hole 22 ', the trigger lever 20 in a pivoting movement in which his training finger 20 ' operates the lock of the switchgear 1, in the direction of a tripping, so that the electrical circuit downstream of this equipment 1 is turned off. This movement of extraction of the lock 22 brings simultaneously the cam 22 "in front of the electrical contact 16 and performs the electronic circuit 5 and therefore electromagnets 6 and 12 cut off.

    Comme indiqué plus haut à propos du premier mode de réalisation, le verrou 22 peut être maintenu dans sa position de condamnation par mise en place dans l'un des perçages 22' d'un cadenas ou d'un fil de plombage.As mentioned above about the first mode of embodiment, the latch 22 can be kept in its position condemnation by fitting a padlock in one of the holes 22 'or a sealing wire.

    Enfin, selon une autre caractéristique de l'invention, et comme il ressort plus particulièrement des figures 10 et 13 des dessins annexés, le verrou de condamnation 22 est pourvu d'un moyen 24 de blocage du levier d'enclenchement 18 en position de repos, constitué par une surface plane dudit verrou 22 coopérant, en position de condamnation du verrou 22, avec une partie de la section de l'axe 18' du levier d'enclenchement 18 de forme correspondante. Ce moyen 24 permet donc un blocage mécanique du levier 18 dans la position de condamnation du verrou 22 par application de deux surfaces l'une contre l'autre.Finally, according to another characteristic of the invention, and as it appears more particularly from Figures 10 and 13 of the accompanying drawings, the locking latch 22 is provided with means 24 for locking the lever latching 18 in the rest position, consisting of a flat surface of said cooperating latch 22, in the latching position of latch 22, with part of the section of the axis 18 ′ of the engagement lever 18 of shape corresponding. This means 24 therefore allows mechanical locking of the lever 18 in the locking position of the lock 22 by application of two surfaces against each other.

    Le dispositif de commande à distance selon la variante de réalisation représentée aux figures 10 à 14 des dessins annexés permet une réalisation plus compacte des premier et deuxième moyens d'actionnement 3 et 4.The remote control device according to the variant of embodiment shown in Figures 10 to 14 of the accompanying drawings allows a more compact realization of the first and second actuation means 3 and 4.

    Grâce à l'invention, il est possible de réaliser un dispositif de commande à distance pour appareillage modulaire de protection en particulier pour enclencher ou déclencher à distance, par l'intermédiaire d'éléments du type interrupteur ou contacteur ou d'autres automatismes, un appareillage de protection modulaire tel qu'un disjoncteur, un interrupteur différentiel ou un disjoncteur différentiel ou un autre appareil de ce type tout en garantissant une manoeuvre très rapide des appareils commandés assurant la pérennité de leur contact.Thanks to the invention, it is possible to produce a device for remote control for modular protective equipment in particular for switching on or off remotely, via of elements of the switch or contactor type or of other automatic devices, a modular protective equipment such as a circuit breaker, a switch earth leakage circuit breaker or similar device while guaranteeing very rapid operation of the devices ordered ensuring the sustainability of their contact.

    En effet, le dispositif conforme à l'invention permet une manoeuvre très rapide des appareils à commander, de sorte qu'un échauffement non désiré des contacts ne peut pas se produire. Par ailleurs, ce dispositif permet également un déclenchement commandé à distance, en particulier pour effectuer une mise hors circuit provisoire des circuits.Indeed, the device according to the invention allows a very quick operation of the devices to be controlled, so that a unwanted heating of the contacts cannot occur. Otherwise, this device also allows remote controlled triggering, particular for temporarily shutting down circuits.

    Enfin, le dispositif conforme à la présente invention permet d'assurer la sécurité des opérateurs intervenants sur les appareillages électriques grâce à la prévision d'un verrou de condamnation évitant toute manoeuvre non voulue.Finally, the device according to the present invention allows to ensure the safety of operators working on equipment electric thanks to the provision of a locking lock preventing any unwanted operation.

    Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des différents éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the modes of embodiment described and shown in the accompanying drawings. Modifications remain possible, particularly from the point of view of the constitution of different elements or by substitution of technical equivalents, without leaving provided the scope of protection of the invention.
