Description

La présente invention concerne un appareil actionneur d'au moins un appareil électrique de protection de ligne de type disjoncteur à boîtier de même profil accolé à lui sur un rail de fixation. Il s'agit typiquement d'un dispositif ou auxiliaire de réarmement, qui donne la possibilité d'intervenir sur des installations électriques localisées à distance, permettant le cas échéant d'éviter la mobilisation de personnel de surveillance, ou l'arrêt prolongé de l'alimentation d'un site, ou encore simplement des déplacements qui s'avèrent inutiles du fait de l'existence des appareils de l'invention. Un tel dispositif de réarmement est par exemple connu du document EP 2 383 766 A1 .The present invention relates to an actuator apparatus of at least one type circuit-breaker-type electrical circuit breaker with the same profile attached to it on a fixing rail. It is typically a rearming device or auxiliary, which gives the possibility to intervene on remotely located electrical installations, making it possible, if necessary, to avoid the mobilization of supervisory personnel, or the prolonged shutdown of the equipment. supply of a site, or simply displacements that prove useless because of the existence of the apparatus of the invention. Such a rearming device is for example known from the document EP 2 383 766 A1 .

Secondairement, la possibilité d'agir sur des installations électriques à distance peut s'avérer avantageuse sur un plan sécuritaire, le contrôle hors site d'un équipement pouvant être mis à profit pour éviter une prise de risque inutile.Secondly, the possibility of acting on remote electrical installations can prove to be advantageous on a safety level, the off-site control of a piece of equipment that can be used to avoid unnecessary risk taking.

Les appareils actionneurs de l'invention sont accolés à des appareils de protection dotés d'une serrure mécanique destinée à couper au moins une ligne protégée, et qui sont munis d'une manette de commande manuelle déplaçable en au moins deux positions correspondant respectivement à l'ouverture et à la fermeture de la ou des lignes. Pour pouvoir agir sur au moins un appareil de protection de ligne, l'appareil actionneur ou auxiliaire de réarmement selon l'invention comprend :

  • des moyens moteurs et un système de transmission consistant en un jeu d'engrenages reliant les moyens moteurs et un levier rotatif solidarisable à la manette de commande de l'appareil de protection accolé,
  • lesdits moyens moteurs étant aptes à mouvoir le levier entre deux positions extrêmes correspondants aux positions d'ouverture et de fermeture de la manette de l'appareil de protection.
The actuating devices of the invention are contiguous to protective devices provided with a mechanical lock intended to cut at least one protected line, and which are provided with a manual control lever movable in at least two positions respectively corresponding to the opening and closing of the line or lines. In order to be able to act on at least one line protection device, the actuator or auxiliary resetting device according to the invention comprises:
  • motor means and a transmission system consisting of a set of gears connecting the drive means and a rotatable lever integral with the control lever of the attached protective device,
  • said motor means being able to move the lever between two extreme positions corresponding to the open and closed positions of the handle of the protective device.

Du fait des contraintes mécaniques propres à ces mouvements, et des résistances résultant notamment des serrures sur lesquelles sont basés les appareils de protection, l'armement et le désarmement de tels appareils requiert la mise en oeuvre d'une amplitude prédéterminée du déplacement du levier avec une certaine puissance, impliquant notamment une cinématique particulière dans l'auxiliaire de réarmement.Due to the mechanical stresses specific to these movements, and to resistances resulting in particular from the locks on which the protection devices are based, the arming and disarming of such devices requires the implementation of a predetermined amplitude of the movement of the lever with a certain power, particularly involving a particular kinematics in the rearming aid.

Par ailleurs, ce type de dispositifs peut également servir à communiquer à distance l'état des appareils de protection auxquels ils sont adjoints. Ainsi, ils doivent pouvoir restituer une information sur la nature d'un déclenchement, soit à la suite d'un défaut sur la ligne, soit par action manuelle d'un utilisateur. Enfin, ils sont susceptibles de faire déclencher les produits auxquels ils sont associés même en cas de blocage de la manette, et doivent dès lors être conçus à cet effet.Moreover, this type of device can also be used to remotely communicate the state of the protective devices with which they are associated. Thus, they must be able to provide information on the nature of a trigger, either as a result of a fault on the line, or by manual action of a user. Finally, they are likely to trigger the products to which they are associated even in case of blocking of the controller, and must therefore be designed for this purpose.

Pour remplir ces fonctions, et d'autres qui apparaîtront dans la suite de la description, l'appareil actionneur de l'invention, qui doit présenter une possibilité de couplage / découplage du système de transmission et du levier pour permettre l'actionnement des manettes sans interférer avec le système de transmission, prévoit que le système de transmission comporte des moyens rotatifs d'entrainement du levier rotatif dans deux sens de rotation opposés, lesdits moyens d'entrainement ayant un débattement angulaire sensiblement égal à deux fois le trajet angulaire couvert par les manettes des appareils de protection de ligne associés, des moyens de commande des moyens moteurs permettant de réinitialiser la position des moyens d'entrainement après un entrainement de la manette en l'une de ses positions extrêmes en un point milieu entre lesdites positions par rotation inverse égale à un trajet angulaire couvert par la manette. L'appareil actionneur est caractérisé en ce que les moyens d'entrainement consistent en deux couples de faces d'orientation opposée appartenant à deux engrenages et qui sont rotatifs autour d'un même axe, chaque face de l'un pouvant entrer en contact avec une face orientée à l'opposé de l'autre, la valeur du secteur angulaire séparant les faces opposées de l'engrenage d'entrainement étant la moitié de la valeur du secteur angulaire séparant les faces opposées de l'engrenage entrainé, et en ce que les faces opposées entrant en contact appartiennent à des butées solidaires desdits engrenages, dépassant sur chaque engrenage d'une face d'allure perpendiculaire à l'axe de rotation, et dont les trajets interfèrent en cas de rotation desdits engrenages.To fulfill these functions, and others which will appear in the following description, the actuator device of the invention, which must have a possibility of coupling / decoupling of the transmission system and the lever to allow the actuation of the levers without interfering with the transmission system, provides that the transmission system comprises rotary means for driving the rotary lever in two opposite directions of rotation, said drive means having an angular displacement substantially equal to twice the angular path covered by the handles of the associated line protection devices, control means of the motor means for resetting the position of the drive means after a drive of the lever at one of its extreme positions at a midpoint between said rotational positions inverse equals an angular path covered by the joystick. The actuating apparatus is characterized in that the drive means consist of two pairs of faces of opposite orientation belonging to two gears and which are rotatable about the same axis, each face of the one being able to come into contact with one side facing away from the other, the value of the angular sector separating the opposite faces of the drive gear being half of the value of the angular sector separating the opposite faces of the driven gear, and in that that the opposite faces coming into contact belong to abutments integral with said gears, protruding on each gear of a face of course perpendicular to the axis of rotation, and whose paths interfere with the rotation of said gears.

Le couplage / découplage est donc en fait basé sur la coopération entre les moyens moteurs et des butées dont le positionnement est calculé pour que l'entrainement réalisé par le levier, en bout de chaîne du système de transmission, soit égal à l'amplitude de la rotation de la manette d'un appareil relié à celui de l'invention. A l'issue de cet entrainement, l'engrenage d'entrainement est dans la plupart des cas ramené à sa position initiale, et il se retrouve par conséquent au contact de l'autre face du levier entrainé, prêt à l'entrainer dans l'autre sens. Le blocage de la manette dans la position dans laquelle elle a été entraînée peut cependant également être recherché, et dans ce cas, il n'y a pas de retour en position milieu.The coupling / decoupling is in fact based on the cooperation between the motor means and stops whose positioning is calculated so that the drive performed by the lever at the end of the transmission system chain is equal to the amplitude of the rotation of the handle of a device connected to that of the invention. At the end of this training, the drive gear is in most cases brought back to its initial position, and it is therefore in contact with the other face of the lever trained, ready to train in the other direction. The lock of the joystick in the position in which it was driven can however also be sought, and in this case, there is no return to the middle position.

Selon une configuration possible, un débattement rotatif relatif est obtenu parce que d'une part l'un des engrenages du système de transmission comporte une came à deux butées d'allure radiale placée sur une couronne solidaire dudit engrenage et de diamètre supérieur au diamètre d'engrènement, et que d'autre part un relief oblong dépasse d'un second engrenage du système de transmission coaxial au premier, ledit relief et les butées étant localisés radialement respectivement sur la couronne et sur une face du second pignon de manière à avoir une course qui interfère en cas de rotation.According to one possible configuration, a relative rotational movement is obtained because, on the one hand, one of the gears of the transmission system comprises a cam with two stops of radial appearance placed on a ring integral with said gear and with a diameter greater than the diameter d meshing, and that on the other hand an elongated relief protrudes from a second gear of the transmission system coaxial with the first, said relief and stops being located radially respectively on the crown and on one side of the second pinion so as to have a stroke that interferes in case of rotation.

L'idée générale dans toutes ces configurations est que les moyens moteurs peuvent agir sur le levier, lui-même solidarisable à la ou aux manettes de commande d'au moins un appareil accolé de façon à commander la position desdites manettes en vue d'ouvrir ou de fermer les contacts de l'appareil de protection accolé. Une fois commandée, ladite manette doit pouvoir être manoeuvrée sans agir en retour sur le levier de l'appareil de l'invention, par exemple un auxiliaire de réarmement, ou être bloquée s'il y a lieu.The general idea in all these configurations is that the motor means can act on the lever, which can itself be attached to the control lever (s) of at least one device attached to control the position of said joysticks to open or close the contacts of the attached protective device. Once controlled, said lever must be operable without acting on the lever of the apparatus of the invention, for example a rearming aid, or be blocked if necessary.

Selon une possibilité, les moyens moteurs peuvent consister en un moteur à courant continu.According to one possibility, the motor means may consist of a DC motor.

Le dispositif de découplage du système de transmission et du levier est donc mis en oeuvre via les moyens de commande de manière à ce que, après avoir commandé le moteur dans un sens, il réponde à une commande exactement inverse, pour piloter les moyens d'entrainement en sens inverse de telle sorte qu'une opération manuelle sur les manettes, dans l'unique sens disponible, soit éventuellement possible.The decoupling device of the transmission system and the lever is thus implemented via the control means so that, after having commanded the engine in one direction, it responds to an exactly opposite command, to control the means of control. drive in the opposite direction so that a manual operation on the joysticks, in the only available direction, is possibly possible.

Le dispositif de l'invention peut par ailleurs comporter un ressort de torsion disposé entre un engrenage du système de transmission et une butée solidarisée au boîtier. Les fonctions d'un tel ressort peuvent être d'équilibrer les efforts nécessaires à l'armement et au désarmement, en accumulant de l'énergie au désarmement et en la restituant au moment de l'armement. Le ressort est alors contraint dans le sens du désarmement, puis libéré pour l'armement. Alternativement, la fonction peut encore être d'accumuler de l'énergie dans des phases de repos, pour pouvoir en disposer en phase active, par exemple au réarmement.The device of the invention may further comprise a torsion spring disposed between a gear of the transmission system and a stop secured to the housing. The functions of such a spring can be to balance the forces required for arming and disarmament, accumulating energy disarmament and restoring it at the time of arming. The spring is then forced in the direction of disarmament, then released for arming. Alternatively, the function can still be to accumulate energy in idle phases, to be able to dispose of it in the active phase, for example at reset.

L'appareil actionneur selon l'invention peut par ailleurs comporter des moyens pour actionner la serrure de l'appareil de protection accolé lors de l'entrainement du levier dans la direction d'ouverture de la manette.The actuator apparatus according to the invention may further comprise means for actuating the lock of the protective device attached during the driving of the lever in the opening direction of the joystick.

Ces moyens, selon une possibilité, peuvent consister en une biellette entrainée dans une direction d'allure perpendiculaire à l'axe de rotation du levier par les moyens d'entrainement, et comprenant un bras de liaison avec la serrure de l'appareil de protection accolé, ledit bras présentant une interface mécanique de liaison avec l'appareil de protection s'exerçant via un orifice pratiqué dans le boîtier de l'appareil actionneur.These means, according to one possibility, may consist of a rod driven in a direction of gait perpendicular to the axis of rotation of the lever by the drive means, and comprising a link arm with the lock of the protective device coupled, said arm having a mechanical interface for connection with the protection device acting via an orifice made in the housing of the actuating device.

L'appareil de l'invention peut également comporter des moyens de visualisation de l'état de la serrure de chaque appareil de protection accolé.The apparatus of the invention may also include means for displaying the state of the lock of each attached protective device.

Selon une possibilité, ces moyens de visualisation peuvent consister en une protubérance saillant de la biellette et visible à travers une fenêtre ou un orifice pratiqué dans le boîtier de l'appareil actionneur.According to one possibility, these viewing means may consist of a projection protruding from the rod and visible through a window or an orifice formed in the housing of the actuating device.

L'invention va à présent être décrite plus en détail, en référence aux figures annexées, pour lesquelles :

  • la figure 1 représente, en vue perspective, un appareil actionneur selon l'invention ;
  • la figure 2 montre le levier, en représentation en perspective ; et
  • la figure 3 illustre la liaison mécanique entre la biellette d'actionnement/visualisation d'une serrure d'appareil électrique accolé ;
  • la figure 4 représente, en vue perspective, le levier et la portion dentée ; et
  • la figure 5 montre un appareil actionneur vu selon une direction opposée à celle de la figure 1, mettant en exergue la biellette de la figure précédente.
The invention will now be described in more detail, with reference to the appended figures, for which:
  • the figure 1 represents, in perspective view, an actuator apparatus according to the invention;
  • the figure 2 shows the lever, in perspective representation; and
  • the figure 3 illustrates the mechanical connection between the actuating rod / visualization of an attached electrical appliance lock;
  • the figure 4 represents, in perspective view, the lever and the toothed portion; and
  • the figure 5 shows an actuator device seen in a direction opposite to that of the figure 1 , highlighting the rod of the previous figure.

En référence à la figure 1, qui représente un exemple possible de configuration qui n'est pas couvert par les revendications, mais illustre le mode de fonctionnement de l'appareil actionneur revendiqué, le dispositif actionneur de l'invention (1) comporte un boîtier (2) isolant qui présente le même profil que les produits modulaires de type disjoncteur auquel il est accolé, notamment au niveau de la façade (3) munie d'un levier (4) rotatif et de la semelle (5) dont le profil particulier permet au produit d'être fixé sur un rail normalisé à côté des produits auxquels il sert d'auxiliaire.With reference to the figure 1 , which represents a possible example of a configuration which is not covered by the claims, but illustrates the mode of operation of the claimed actuator apparatus, the actuator device of the invention (1) comprises an insulating casing (2) which presents the same profile as the modular circuit breaker type products to which it is attached, in particular at the front (3) provided with a lever (4) rotary and the sole (5) whose particular profile allows the product to be attached to a standard rail next to the products it serves as an auxiliary.

L'appareil actionneur (1) comporte des moyens de connexion (6), en l'espèce constitués d'une cage et vis (7) surmontant un dispositif de fixation rapide à lame ressort (8), autorisant respectivement par exemple la fixation de conducteurs de commande et d'une barre de pontage.The actuator apparatus (1) comprises connection means (6), in this case consisting of a cage and screw (7) surmounting a spring blade quick-fastening device (8), respectively allowing, for example, the fixation of control conductors and a bridge bar.

Pour remplir sa fonction d'auxiliaire de réarmement / désarmement, l'appareil actionneur (1) de l'invention comporte des moyens moteurs, en l'occurrence un moteur à courant continu (9) dont l'arbre de sortie est muni d'une vis sans fin (10) coopérant avec un jeu d'engrenages (11, 12, 13) transformant notamment le mouvement de rotation selon l'axe du moteur (9) en un mouvement de rotation parallèle à l'axe de pivotement du levier (4). Ce jeu d'engrenages (11, 12, 13) permet également d'adapter le couple et l'amplitude du mouvement rotatif en vue de commander la position dudit levier (4) entre deux positions correspondant aux positions d'ouverture et de fermeture des contacts du produit modulaire qui lui est accolé.To fulfill its function of reset / disarming auxiliary, the actuating device (1) of the invention comprises motor means, in this case a DC motor (9) whose output shaft is provided with an endless screw (10) cooperating with a set of gears (11, 12, 13), in particular transforming the rotational movement along the axis of the motor (9) into a rotational movement parallel to the axis of pivoting of the lever (4). This set of gears (11, 12, 13) also makes it possible to adapt the torque and the amplitude of the rotary movement in order to control the position of said lever (4) between two positions corresponding to the opening and closing positions of the contacts of the modular product that is attached to it.

L'engrenage (13) coopère avec une portion dentée (14) montée coaxialement au levier (4), comme cela sera décrit plus en détail dans la suite. Cette portion dentée (14) est libre en rotation par rapport au levier (4) selon un débattement angulaire limité par deux faces opposées faisant office de butées radiales (44, 45) d'un logement (43) prenant la forme d'un secteur angulaire évidé du levier (4), dans lequel est insérée ladite portion dentée (14) (voir en figure 2). Ainsi, en fonctionnement, lorsqu'un signal de commande est envoyé au moteur à courant continu (9), celui-ci actionne le jeu d'engrenages (11, 12, 13) et par conséquent la portion dentée (14) de telle sorte que, lorsque cette dernière est en butée contre l'une des butées (44, 45) du levier (4), elle entraine également le levier (4) suivant un trajet angulaire égal à celui de la manette passant de sa position d'ouverture à sa position de fermeture ou l'inverse. Le moteur repart ensuite en sens inverse et fait exécuter à la portion dentée (14) un trajet angulaire inversé. L'amplitude angulaire totale de la portion (14) est donc égale à deux fois le trajet angulaire correspondant à un changement d'état de la manette du produit modulaire associé.The gear (13) cooperates with a toothed portion (14) mounted coaxially with the lever (4), as will be described in more detail below. This toothed portion (14) is free to rotate with respect to the lever (4) in an angular displacement limited by two opposite faces acting as radial stops (44, 45) of a housing (43) in the form of a sector angular recess of the lever (4), into which is inserted said toothed portion (14) (see FIG. figure 2 ). Thus, in operation, when a control signal is sent to the DC motor (9), it operates the gear set (11, 12, 13) and consequently the toothed portion (14) in such a way that when the latter is in abutment against one of the stops (44, 45) of the lever (4), it also causes the lever (4) along an angular path equal to that of the lever passing from its open position in its closed position or vice versa. The motor then starts in the opposite direction and causes the toothed portion (14) to execute an inverted angular path. The total angular amplitude of the portion (14) is thus equal to twice the angular path corresponding to a change of state of the lever of the associated modular product.

La figure 2 montre le levier (4) seul sous une certaine orientation, faisant notamment apparaître sa portion centrale située entre les deux plots latéraux (41, 42) lui permettant de pivoter dans le boîtier (2) de l'appareil actionneur (1) de l'invention. Cette portion centrale comporte un logement (43) dans lequel peut pivoter l'anneau central (15) de la portion dentée (14) (voir en figure 3). La figure 2 fait également clairement apparaître les deux faces ou butées (44, 45) orientées radialement par rapport à l'axe de rotation matérialisé par les plots latéraux (41, 42), et qui limitent en pratique la rotation de la portion dentée de la façon expliquée ci-après.The figure 2 shows the lever (4) alone in a certain orientation, in particular showing its central portion located between the two lateral pads (41, 42) allowing it to pivot in the housing (2) of the actuator apparatus (1) of the invention. This central portion comprises a housing (43) in which the central ring (15) of the toothed portion (14) can pivot (see FIG. figure 3 ). The figure 2 also clearly shows the two faces or abutments (44, 45) oriented radially with respect to the axis of rotation represented by the lateral studs (41, 42), and which in practice limit the rotation of the toothed portion in the manner explained below.

Les faces latérales d'allure radiale et opposées (16, 17) de la portion dentée (14) telle qu'elle apparaît en figure 3, butent en fait contre les parois (44) et (45) orientées sensiblement selon la même direction du logement (43), constituant ainsi les butées du débattement angulaire de la portion d'engrenage (14) dans le levier (4). C'est ce qui ressort de la figure 4 qui montre la coopération entre la portion dentée (14) et le levier (4), leur rotation relative étant bornée par les contacts des couples de faces (16, 44 ; 17, 45).The radial and opposite side faces (16, 17) of the toothed portion (14) as it appears in FIG. figure 3 , in fact abut against the walls (44) and (45) oriented substantially in the same direction of the housing (43), thus constituting the abutments of the angular displacement of the gear portion (14) in the lever (4). This is what emerges from the figure 4 which shows the cooperation between the toothed portion (14) and the lever (4), their relative rotation being limited by the contacts of the pairs of faces (16, 44; 17, 45).

Une biellette (20), coopérant avec un muret (18) de la portion dentée (14), et qui apparaît aussi en figure 5, est munie de deux excroissances (21) et (22) permettant d'une part d'actionner la serrure mécanique de l'appareil de protection de ligne auquel l'auxiliaire de réarmement de l'invention est accolé, et d'autre part de donner des indications sur le type de déclenchement dudit appareil de protection.A rod (20) cooperating with a wall (18) of the toothed portion (14), which also appears in figure 5 , is provided with two protuberances (21) and (22) for operating on the one hand the mechanical lock of the line protection device to which the rearming aid of the invention is attached, and secondly to give indications on the type of tripping of said protection device.

Ainsi, l'excroissance ou bras (21) peut par exemple dépasse du boîtier (2) de l'appareil actionneur (1) de l'invention, par l'intermédiaire d'une fenêtre (non représentée) dont les dimensions prennent en compte la possibilité de son déplacement en translation relativement au boîtier (2). Ce déplacement est provoqué par la portion dentée (14), qui entraîne au moyen d'un muret (18) un plot (23) dépassant d'une extrémité de la biellette (20). Selon sa position, relevée par des capteurs, le bras (22) indique la position de la biellette (20), et par conséquent du bras (21), montrant si la biellette a été déplacée pour commander un déclenchement de la serrure du produit associé.Thus, the protrusion or arm (21) can for example protrude from the housing (2) of the actuator apparatus (1) of the invention, via a window (not shown) whose dimensions take into account the possibility of its displacement in translation relative to the housing (2). This displacement is caused by the toothed portion (14), which leads by means of a wall (18) a stud (23) protruding from one end of the rod (20). According to its position, raised by sensors, the arm (22) indicates the position of the link (20), and therefore of the arm (21), showing whether the link has been moved to control a release of the lock of the associated product .

La disposition de la biellette (20) relativement au boîtier (1) apparaît dans les figures 1 et 5, qui montrent l'intérieur de l'appareil (1) de l'invention selon deux vues sensiblement opposées.The arrangement of the link (20) relative to the housing (1) appears in the figures 1 and 5 which show the inside of the apparatus (1) of the invention in two substantially opposite views.
