Les appareils de coupure électriques concernés par l'invention sont des interrupteurs à deux positions 0-1, des commutateurs à deux positions I-IL des commutateurs à trois positions I-O-ïï, des commutateurs à recouvrement I-I+II-II ou similaire. Ces appareils de coupure électrique comportent habituellement un ou plusieurs modules de coupure empilés. Les modules de coupure sont de type connu et comportent des contacts mobiles actionnés par un axe de commande rotatif via un mécanisme de transformation de mouvement à came ou similaire. Pour réaliser une fonction "commutation", dans le cas par exemple d'un changement de source d'alimentation entre le réseau et un groupe de secours, on utilise deux modules de coupure montés en parallèle et reliés chacun à une source d'alimentation, le module de commande étant soit manuel, soit automatisé pour les gros interrupteurs ou commutateurs industriels. L'automatisation est généralement réalisée au moyen d'un moto- réducteur électrique dont l'arbre moteur est couplé par une transmission à l'axe de commande des modules de coupure.The electrical cut-off devices to which the invention relates are two-position switches 0-1, two-position switches I-II, three-position switches IO-I, overlap switches I-I + II-II, or the like. . These electrical cut-off devices usually include one or more stacked break modules. The breaking modules are of known type and comprise movable contacts actuated by a rotary control shaft via a cam movement transformation mechanism or the like. To perform a "switching" function, in the case for example of a change of power source between the network and a backup group, two parallel cut-off modules are used, each connected to a power source, the control module being either manual or automated for large switches or switches industrial. The automation is generally performed by means of an electric gear motor whose drive shaft is coupled by a transmission to the control axis of the breaking modules.
Cette technologie bien connue présente de nombreux inconvénients. Son coût important ne lui permet pas d'équiper des appareils de coupure de petits calibres. Son encombrement relativement important nécessite de sur-dimensionner le module de commande et de ce fait le volume de l'ensemble de l'appareil de coupure est pénalisé. De plus, il nécessite une alimentation électrique spécifique pour alimenter le moteur, le mettant ainsi hors service en cas de coupure de courant et rendant le module de commande non opérationnel. Enfin, ce type de motorisation a une inertie propre qui rallonge les temps de commutation, ce qui peut être préjudiciable pour l'appareil lui- même. Si l'on souhaite passer en mode manuel, il est nécessaire d'entraîner simultanément le moto-réduction ou de le débrayer, ce qui impose des couples de manœuvres plus importants ou des mécanismes complémentaires.This well-known technology has many disadvantages. Its high cost does not allow it to equip devices of cut small caliber. Its relatively large size requires over-size control module and therefore the volume of the entire device cut is penalized. In addition, it requires a specific power supply to power the engine, thus turning it off in the event of a power failure and rendering the control module non-operational. Finally, this type of drive has a clean inertia that increases the switching time, which can be detrimental to the device itself. If you want to switch to manual mode, it is necessary to simultaneously drive the motor-reduction or disengage, which requires more important maneuvers or additional mechanisms.
La publication DE-C-574 857 décrit une autre technologie appliquée à un interrupteur à bain d'huile, destiné aux réseaux haute tension. Le mécanisme de commande de cet interrupteur comporte un vérin à air comprimé dont la tige de piston forme une crémaillère engrenant un pignon couplé à l'axe de commande de l'interrupteur par une roue à rochet et des cliquets n'autorisant son entraînement que dans un sens de rotation, la tige de piston étant également assujettie à un ressort de rappel. Ce type d'actionneur par vérin pneumatique présente l'inconvénient majeur de nécessiter une alimentation spécifique et régulée en air comprimé ainsi que des moyens de raccordement et de commande par électrovanne qu'il faut également contrôler. De ce fait, ce mécanisme de commande est très complexe, coûteux et pas du tout adapté à la distribution électrique en basse et moyenne tension et de faible calibre. De plus, le rendement de ce mécanisme de commande est médiocre, sa qualité de commutation incertaine et son encombrement axial très important. Exposé de l'inventionPublication DE-C-574 857 describes another technology applied to an oil bath switch for high voltage networks. The control mechanism of this switch comprises a compressed air cylinder whose piston rod forms a rack meshing with a pinion coupled to the control axis of the switch by a ratchet wheel and ratchets allowing its training only in a direction of rotation, the piston rod being also subject to a return spring. This type of pneumatic cylinder actuator has the major disadvantage of requiring a specific supply and regulated compressed air as well as connection and control means by solenoid valve which must also be controlled. Therefore, this control mechanism is very complex, expensive and not at all suitable for low and medium voltage electrical distribution and low caliber. In addition, the efficiency of this control mechanism is poor, its switching quality uncertain and its axial size very important. Presentation of the invention

Cette clé 14 peut être remplacée par tout autre organe de préhension équivalent comme une poignée intégrée ou rapportée. Il comporte également en face avant une fenêtre 16 permettant de visualiser l'état de commutation de l'appareil de coupure 1 : 1, 0 ou II, à savoir la position des contacts, une languette de cadenassage 17 permettant de verrouiller le module de commande 10 dans l'un ou l'autre état de commutation de l'appareil de coupure 1. Le capot 12 est par ailleurs couplé à un micro-interrupteur (non représenté) commandé par un ergot 18 pour interdire le fonctionnement du module de commande 10, en mode automatisé, tant que le capot 12 est ouvert. Tout autre moyen de sécurité équivalent peut convenir. Ce boîtier 11 comporte également un bornier 19 pour le raccordement électrique de l'alimentation et de la commande du mécanisme d'actionnement automatisé 30 détaillé ci-après.This housing 11 comprises two half-shells assembled by interlocking and screwing or the like, preferably made by molding electrically insulating synthetic materials. It comprises, on the front face, a cover 12, preferably translucent, pivotally mounted around a hinge 13 to access a key 14 making it possible to maneuver the control module 10, in manual mode, by introducing it into a housing 15 of a manual actuation mechanism 60, detailed below. This key 14 can be replaced by any other equivalent gripping member such as an integrated handle or reported.

The cover 12 is also coupled to a microswitch (not shown) controlled by a pin 18 to prohibit the operation of the control module 10 , in automated mode, as long as the cover 12 is open. Any other equivalent means of security may be suitable. This housing 11 also comprises a terminal block 19 for the electrical connection of the power supply and the control of the automated actuation mechanism 30 detailed below.
En référence aux figures 3 à 7, le module de commande 10 comporte un premier mécanisme d'actionnement dit « automatisé » 30, destiné à être couplé directement à l'axe de commande de l'appareil de coupure 1 au moyen d'un accouplement mécanique 3, suivi d'un second mécanisme d'actionnement dit « manuel » 60 disposé dans l'alignement du premier.With reference to FIGS. 3 to 7, the control module 10 comprises a first so-called "automated" actuating mechanism 30, intended to be coupled directly to the control axis of the cut-off device 1 by means of a coupling mechanical 3, followed by a second actuating mechanism called "manual" 60 arranged in alignment with the first.
Le mécanisme d'actionnement automatisé 30 comporte un actionneur en translation couplé à un dispositif de transformation du mouvement de translation de l' actionneur en un mouvement de rotation qui sera transmis à l'axe de commande de l'appareil de coupure 1 par un dispositif de transmission. Dans l'exemple représenté, F actionneur comporte deux électroaimants 31, alignés et en opposition. Chaque électroaimant 31 comporte de manière connue une bobine d'induction 32 alimentée électriquement et un noyau plongeur 33 mobile entre une position sortie ou position de repos, lorsque la bobine d'induction 32 n'est pas excitée, et une position rentrée ou position de travail, lorsque la bobine d'induction 32 est excitée, le retour en position sortie étant assuré par des moyens de rappel. Les bobines d'induction 32 sont avantageusement alimentées directement par l'appareil de coupure 1 au moyen de prises de tension spécifiques (non représentées), garantissant l'autonomie énergétique du module de commande 10, L'extrémité du noyau plongeur 33 de chaque électroaimant 31 est reliée à un même coulisseau 34 pourvu d'une crémaillère 35. Ce coulisseau 34 est mobile en translation par rapport au boîtier 11 entre trois positions : une position centrale C stable, lorsque les électroaimants 31 ne sont pas alimentés électriquement, une position gauche G lorsque l' électroaimant 31 de gauche est excité et une position droite D lorsque l' électroaimant 31 de droite est excité. Au moins la position centrale C est indexée par un ergot 36 (cf. fig. 5) prévu sur le flanc du coulisseau 34 coopérant avec une lame ressort en V (non représentée) prévue dans le boîtier 11. Bien entendu, tout autre moyen d'indexage est possible. Les moyens de rappel des noyaux plongeurs 33 en position sortie sont, dans l'exemple représenté, constitués d'un ressort 37 hélicoïdal de compression disposé entre le boîtier 11 et le coulisseau 34 (voir fig. 8) et permet de rappeler le coulisseau 34 dans sa position centrale C lorsque les électroaimants 31 ne sont plus excités. Ces moyens de rappel peuvent être constitués par tout autre organe ressort équivalent, disposé entre le coulisseau 34 et le boîtier 11, entre les noyaux plongeurs 33 et le boîtier 11 ou entre les noyaux plongeurs 33 et la partie fixe des électroaimants 31.

Le module de commande 10 peut ne comporter qu'un électroaimant 31 couplé au coulisseau 34 dans le cas d'un appareil de coupure 1 à un seul sens de rotation.The automated actuation mechanism 30 comprises a translational actuator coupled to a device for converting the translational movement of the actuator into a rotational movement which will be transmitted to the control axis of the switching device 1 by a device of transmission. In the example shown, the actuator comprises two electromagnets 31, aligned and in opposition. Each electromagnet 31 comprises in known manner an induction coil 32 electrically powered and a plunger 33 movable between an output position or rest position, when the induction coil 32 is not excited, and a retracted position or position of work, when the induction coil 32 is excited, the return to the extended position being provided by return means. The induction coils 32 are advantageously fed directly by the switching device 1 by means of specific voltage taps (not shown), ensuring the energy autonomy of the control module 10, the end of the plunger core 33 of each electromagnet 31 is connected to a single slide 34 provided with a rack 35. This slide 34 is movable in translation relative to the housing 11 between three positions: a stable central position C, when the electromagnets 31 are not electrically powered, a left position G when the electromagnet 31 on the left is excited and a straight position D when the electromagnet 31 on the right is excited. At least the central position C is indexed by a lug 36 (see FIG 5) provided on the flank of the slide 34 cooperating with a spring blade V (not shown) provided in the housing 11. Of course, any other means d indexing is possible. The return means of the plunging cores 33 in the extended position are, in the example shown, constituted by a helical compression spring 37 disposed between the housing 11 and the slider 34 (see FIG.8) and makes it possible to recall the slider 34. in its central position C when the electromagnets 31 are no longer excited. These return means may be constituted by any other equivalent spring member disposed between the slide 34 and the housing 11, between the plunger cores 33 and the housing 11 or between the plunger cores 33 and the fixed part of the electromagnets 31. Any other arrangement electromagnets 31 and the slide 34 may be suitable, knowing that the arrangement as illustrated makes it possible to limit the size and the dimensions of the control module 10. The control module 10 may comprise only an electromagnet 31 coupled to the slider 34 in the case of a switchgear 1 with only one direction of rotation.

Il comporte deux branches 66a et 66b en appui radial respectivement contre une nervure axiale 64 du manchon 63 et dans un logement 55' d'une paroi radiale 55 s'étendant de la partie discale 54 à distance du tronçon de guidage 53. Le système à action brusque comporte un dispositif de retardement agencé pour n'autoriser la rotation de la broche d'entraînement 50 qu'à partir d'un seuil de compression du ressort de torsion 66 prédéterminé, atteint à partir d'une course prédéterminée des pignons d'entrée 61 et de sortie 62. Ce dispositif de retardement comporte des seconds cliquets 67 montés pivotants dans une paroi intermédiaire 70 fixe par rapport au boîtier 11 et une seconde roue à rochet 68 liée à la broche d'entraînement 50. Cette seconde roue à rochet 68 est disposée entre la paroi intermédiaire 70 et la partie discale 54 de la broche d'entraînement 50 à laquelle elle est liée en rotation par des encoches 68" emboîtées sur des plots 56 prévus sur la partie discale 54 ou similaire. Elle peut être aussi intégrée à la broche d'entraînement 50 pour ne former avec elle qu'une seule pièce. Cette seconde roue à rochet 68 comporte trois dents 68' réparties de manière équidistante, aptes à coopérer avec les seconds cliquets 67 qui sont au nombre de quatre, répartis par paire de cliquets orientés dans des directions opposées, symétriquement par rapport à la broche d'entraînement 50. Les seconds cliquets 67 d'une même paire sont sollicités vers la seconde roue à rochet 68 par un ressort à lame 69 en forme de U logé dans la paroi intermédiaire 70 et sont mobiles entre une position passive dans laquelle ils sont écartés de la seconde roue à rochet 68 et une position active dans laquelle ils sont en appui sur elle sous l'action du ressort à lame 69.A cet effet, chaque second cliquet 67 comporte sur son bord libre, des découpes délimitant plusieurs secteurs 67a-67c : le secteur 67a forme une première aile pour suivre les secondes cames 65 du pignon de sortie 62 provoquant récartement des seconds cliquets 67 et libérant la rotation de la broche d'entraînement 50, le secteur 67b forme une butée pour les dents 68' de la seconde roue à rochet 68 et interdire la rotation de la broche d'entraînement 50 et le secteur 67c forme une seconde aile pour suivre les premières cames 45 du pignon moteur 40 provoquant récartement des seconds cliquets 67 et libérant la rotation de la broche d'entraînement 50 lors du fonctionnement du mécanisme d'actionnement automatisé 30. ' The manual actuation mechanism 60 comprises an input gear 61 provided with the housing 15 accessible on the front of the control module 10 under the hood 12 to accommodate the key 14 for the maneuver. This input gear 61 meshes with an output gear 62 coaxial with the drive spindle 50 in its second portion M. These input and output gears 61 form a bevel gear. The output gear 62 is formed of a toothed sector of about 150 ° integral with a sleeve 63 provided internally with axial ribs 64 and externally with two bosses forming second cams 65. The output gear 62 transmits the rotation of the pinion 61 to the drive pin 50 via a torsion spring 66 mounted coaxially on a guide portion 53 of the drive pin 5O 7 axially supported in a housing 55 "of a part 54. This torsion spring 66 is part of a snap action system which ensures rapid switching of the cut-off device 1 in manual mode.It has two branches 66a and 66b bearing respectively radially against an axial rib 64 of FIG. sleeve 63 and in a housing 55 'of a radial wall 55 extending from the disc portion 54 away from the guide portion 53. The snap action system comprises a delay device arranged to allow rotation of the spindle 50 only from a compression threshold of the torsion spring 66, which reaches from a predetermined stroke of the input 61 and output 62 gears. This delay device comprises second pawls 67 pivotally mounted in an intermediate wall 70 fixed relative to the housing 11 and a second ratchet wheel. 68 This second ratchet wheel 68 is disposed between the intermediate wall 70 and the disc portion 54 of the drive pin 50 to which it is connected in rotation by notches 68 "nested on pads 56 provided on the disc portion 54 or the like It can also be integrated into the drive spindle 50 to form with it only one piece.This second ratchet wheel 68 has three teeth 68 'distributed equidistantly, adapted to cooperate with the second pawls 67 which are four in number, distributed by pair of pawls oriented in opposite directions, symmetrically with respect to the pin of 50. The second pawls 67 of the same pair are biased towards the second ratchet wheel 68 by a U-shaped leaf spring 69 housed in the intermediate wall 70 and are movable between a passive position in which they are separated from each other. the second ratchet wheel 68 and an active position in which they are supported on it under the action of the leaf spring 69. For this purpose, each second pawl 67 has on its free edge, cutouts defining several sectors 67a-67c : the sector 67a forms a first wing to follow the second cams 65 of the output pinion 62 causing the second pawls 67 to recede and, releasing the rotation of the drive pin 50, the sector 67b forms a stop for the teeth 68 'of the second ratchet wheel 68 and prohibit the rotation of the drive pin 50 and the sector 67c forms a second wing to follow the first cams 45 of the drive pinion 40 causing the second ratchet s 67 and releasing the rotation of the drive pin 50 during operation of the automated actuation mechanism 30.

67 permet ainsi de débrayer automatiquement le mécanisme d'actionnement manuel 60 lorsque le mécanisme d'actionnement automatisé 30 est en fonction. Dans ce cas, la broche d'entraînement 50 peut tourner librement sans que le ressort de torsion 66 ne soit sollicité, les pignons d'entrée 61 et de sortie 62 étant réversibles. Inversement, lorsque le mécanisme d'actionnement manuel 60 est en fonction, le mécanisme d'actionnement automatisé 30 est automatiquement débrayé au moyen d'une lèvre de retenue 71 prévue sur la paroi intermédiaire 70, formant une butée pour les premiers cliquets 43 les écartant de la première roue à rochet 51. Cette lèvre de retenue 71 s'étend sur un secteur angulaire d'environ 90° et permet à la broche d'entraînement 50 de tourner librement sans que le pignon moteur 40 ne soit sollicité.67 thus enables the manual actuation mechanism 60 to be disengaged automatically when the automated actuation mechanism 30 is in operation. In that case, the drive spindle 50 can rotate freely without the torsion spring 66 being biased, the input 61 and output 62 gears being reversible. Conversely, when the manual actuation mechanism 60 is in operation, the automated actuation mechanism 30 is automatically disengaged by means of a retaining lip 71 provided on the intermediate wall 70, forming a stop for the first pawls 43 moving them apart. of the first ratchet wheel 51. This retaining lip 71 extends over an angular sector of about 90 ° and allows the drive pin 50 to rotate freely without the motor pinion 40 is biased.

Le disque de cadenassage 80 comporte trois encoches de verrouillage 83 orientées radialement en biais et traversant sa paroi périphérique. Elles sont positionnées de sorte à correspondre aux trois états de commutation de l'appareil de coupure 1 : 1, 0, II dans le but d'offrir la possibilité de cadenasser le module de commande 10 dans l'un de ses états. Un anneau de sécurité 90 est prévu à l'intérieur du disque de cadenassage 80 pour interdire le cadenassage dans l'un ou l'autre état de commutation. A cet effet, il comporte une paroi périphérique formant un masque 91 pour obturer l'une ou l'autre encoche de verrouillage 83. Il est mobile en rotation par rapport au disque de cadenassage 80 au moyen d'un outil (non représenté) introduit dans une encoche 92 accessible au travers d'une lumière 93 sous le boîtier 11. Dans la figure 12A, l'anneau de sécurité 90 est inopérant alors que, dans la figure 12B, il n'autorise le cadenassage que dans l'encoche de verrouillage 83 centrale correspondant à l'état 0 de l'appareil de coupure 1. Le disque de cadenassage 80 peut comporter sur sa paroi périphérique, en regard de la fenêtre 16 en face avant du boîtier 11, un marquage (non représenté) permettant d'indiquer l'état de commutation : I, 0, II, de l'appareil de coupure 1 en fonction de la position angulaire de ce disque.The control module 10 comprises lockout means to prohibit the switching of the breaking device 1. These lockout means comprise the padlocking disc 80 integral in rotation with the drive pin 50, coupled directly to the axis of rotation. control of the switchgear 1, and provided with locking notches 83 adapted to receive the locking finger 84 of the lock tab 17 in the locked position to prevent its rotation. This padlock tongue 17 is accessible on the front face of the housing 11 under the hood 12. It is movable in translation perpendicularly to the lockout disk 80 between a locked position, obtained by manual pulling on a handle 85 to remove it and make the hole accessible. lockout 86 (see Figs 2 and 12B) in which the operator can place a padlock (not shown), and an unlocked position, obtained by a compression spring 87 which recalls the locking tab 17 in the retracted position (cf. 12A) or any other equivalent spring device. The padlocking disc 80 has three locking notches 83 oriented radially at an angle and passing through its peripheral wall. They are positioned to correspond to the three switching states of the switching device 1: 1, 0, II in order to provide the possibility of padlocking the control module 10 in one of its states. A safety ring 90 is provided inside the lockout disk 80 to prohibit the lockout in one or the other state of switching. For this purpose, it comprises a peripheral wall forming a mask 91 for closing one or the other locking notch 83. It is rotatable relative to the lockout disk 80 by means of a tool (not shown) introduced in a notch 92 accessible through a slot 93 under the housing 11. In FIG. 12A, the security ring 90 is inoperative whereas, in FIG. 12B, it authorizes lockout only in the notch of FIG. central locking 83 corresponding to the state 0 of the switchgear 1. The lockout disk 80 may comprise on its peripheral wall, facing the window 16 on the front of the housing 11, a marking (not shown) allowing indicate the switching state: I, 0, II, of the breaking device 1 as a function of the angular position of this disk.
Le module de commande 10 comporte également des moyens de pilotage de la commande des électroaimants 31. Ces moyens de pilotage comportent un disque d'indexage 95 monté à l'extrémité libre 57 de la broche d'entraînement 50 à laquelle il est lié en rotation par une foπne d'emboîtement complémentaire non cylindrique. Ce disque d'indexage 95 s'étend sur un secteur angulaire d'environ 180° et comporte des repères tels que des encoches 96 en périphérie coopérant avec un ou des détecteurs (non représentés) prévus dans le boîtier 11 qui envoie l'information à une carte électronique gérant l'alimentation électrique des électroaimants 31. Dans l'exemple illustré, ces encoches 96 sont au nombre de trois et correspondent aux trois états de commutation de l'appareil de coupure 1. Ces trois états de commutation sont également indexés mécaniquement par une lame ressort en V 97 solidaire du boîtier 11 apte à s'emboîter dans des fentes 98 correspondantes prévues dans le moyeu 99 du disque d'indexage 95. Les détecteurs fonctionnent comme des fins de course, par détection optique ou autre, pour couper l'alimentation de l' électroaimant 31 concerné dès que la position de commutation à atteindre est atteinte. Bien entendu tout autre mode de réalisation de l'indexage et de la détection de la position angulaire de la broche d'entraînement 50, donc de l'état de commutation de l'appareil de coupure 1, est envisageable.The control module 10 also comprises means for controlling the control of the electromagnets 31. These control means comprise an indexing disc 95 mounted at the free end 57 of the drive pin 50 to which it is rotatably connected. by a complementary non-cylindrical fitting thread. This indexing disc 95 extends over an angular sector of about 180 ° and comprises markings such as notches 96 at the periphery cooperating with one or more detectors (not shown) provided in the housing 11 which sends the information to an electronic card managing the power supply of the electromagnets 31. In the example illustrated, these notches 96 are three in number and correspond to the three switching states of the switching device 1. These three switching states are also indexed mechanically by a spring blade V integral with the housing 11 adapted to fit into corresponding slots 98 provided in the hub 99 of the indexing disk 95. The detectors operate as limit switches, by optical detection or otherwise, to cut supplying the electromagnet 31 concerned as soon as the switching position to be reached is reached. Of course, any other embodiment of indexing and detection the angular position of the drive pin 50, and therefore the switching state of the switching device 1, is conceivable.
Le fonctionnement de ce module de commande 10 est détaillé en priorité en référence aux figures 8A-E qui illustrent le mécanisme d'actionnement automatiséThe operation of this control module 10 is detailed in priority with reference to FIGS. 8A-E which illustrate the automated actuation mechanism.

Elles montrent les deux électroaimants 31, le coulisseau 34 et sa crémaillère 35, le pignon moteur 40, les premiers cliquets 43 et la première roue à rochet 51. Elles montrent aussi en traits interrompus la position angulaire de l'axe de commande de 1 ' appareil de coupure 1.They show the two electromagnets 31, the slider 34 and its rack 35, the driving pinion 40, the first pawls 43 and the first ratchet wheel 51. They also show in broken lines the angular position of the control pin of the 1 ' switchgear 1.
A la figure 8A, le mécanisme d'actionnement automatisé 30 est au repos et l'appareil de coupure 1 est à l'état 0 : aucun électroaimant 31 n'est alimenté, les noyaux plongeurs 33 sont en position sortie, le coulisseau 34 est dans sa position centrale C stable, son ressort 37 est au repos, la crémaillère 35 est engrenée avec le pignon moteur 40 immobile, son plan médian passant par C, les premiers cliquets 43 sont en position passive, soulevés par la lèvre de retenue 71, la broche d'entraînement 50 est immobile, son plan médian passant par C.In FIG. 8A, the automated actuation mechanism 30 is at rest and the cut-off device 1 is in state 0: no electromagnet 31 is powered, the plunger cores 33 are in the extended position, the slider 34 is in its stable central position C, its spring 37 is at rest, the rack 35 is in mesh with the stationary motor pinion 40, its median plane passing through C, the first pawls 43 are in the passive position, raised by the retaining lip 71, the drive spindle 50 is stationary, its median plane passing through C.
A la figure 8B, le mécanisme d'actionnement automatisé 30 est en travail mais l'appareil de coupure 1 est toujours à l'état 0 : l' électroaimant 31 de gauche sur les figures est alimenté électriquement, le noyau plongeur 33 commence à se rétracter, entraînant le coulisseau 34 vers la gauche en comprimant le ressort 37, la crémaillère 35 fait tourner le pignon moteur 40 dans le sens horaire R d'environ 15°, le premier cliquet 43 à droite quitte la lèvre de retenue 71 pour engrener une dent 51' de la première roue à rochet 51. Simultanément, les premières cames 45 du pignon moteur 40 soulèvent les seconds cliquets 67 concernés pour libérer la rotation de la seconde roue à rochet 6$. A la figure 8C, le mécanisme d'actionnement automatisé 30 est toujours en travail et l'appareil de coupure 1 a changé d'état en passant de l'état 0 à l'état I : l' électroaimant 31 de gauche est alimenté électriquement, le noyau plongeur 33 est rétracté, le coulisseau 34 est à gauche G, le ressort 37 est comprimé, la crémaillère 35 a fait tourner le pignon moteur 40 dans le sens horaire R d'environ 45° en entraînant la première roue à rochet 51 grâce au premier cliquet 43 de droite en prise avec une de ses dents 51', la broche d'entraînement 50 transmet directement cette rotation à l'axe de commande de l'appareil de coupure 1 qui commute.In FIG. 8B, the automated actuation mechanism 30 is in operation but the cut-off device 1 is always in state 0: the electromagnet 31 on the left in the figures is electrically powered, the plunger core 33 starts to retracting, driving the slider 34 to the left by compressing the spring 37, the rack 35 rotates the drive pinion 40 clockwise R by about 15 °, the first pawl 43 on the right leaves the retaining lip 71 to engage a tooth 51 'of the first ratchet wheel 51. Simultaneously, the first cams 45 of the motor pinion 40 raise the second pawls 67 concerned to release the rotation of the second ratchet wheel 6 $. In FIG. 8C, the automated actuation mechanism 30 is still in operation and the switching device 1 has changed state by passing from the state 0 to the state I: the electromagnet 31 on the left is electrically powered. the plunger 33 is retracted, the slider 34 is left G, the spring 37 is compressed, the rack 35 has rotated the driving pinion 40 in a clockwise direction R by approximately 45 ° by driving the first ratchet wheel 51 thanks to the first ratchet 43 of the right engaged with one of its teeth 51 ', the drive pin 50 directly transmits this rotation to the control axis of the switching device 1 which switches.
A la figure 8D, le mécanisme d'actionnement automatisé 30 est au repos mais l'appareil de coupure 1 est resté à l'état 1 : l' électroaimant 31 de gauche n'est plus alimenté, le ressort 37 s'est détendu ramenant le coulisseau 34 dans sa position centrale C et les noyaux plongeurs 33 en position de repos, la crémaillère 35 a fait tourner le pignon moteur 40 dans le sens inverse R' pour le ramener dans sa position de départ (fig. 8A), les premiers cliquets 43 se sont écartés en passant sur les dents 51' de la première roue à rochet 51 sans l'entraîner, la broche d'entraînement 50 n'a pas bougé restant dans sa position angulaire correspondant à l'état I de la figure 8C.In FIG. 8D, the automated actuation mechanism 30 is at rest but the cut-off device 1 has remained in the state 1: the electromagnet 31 on the left is no longer powered, the spring 37 has relaxed back down the slider 34 in its central position C and the plunger cores 33 in the rest position, the rack 35 has rotated the driving pinion 40 in the opposite direction R 'to return it to its starting position (FIG 8A), the first ratchets 43 have spread by passing over the teeth 51 'of the first ratchet wheel 51 without driving it, the drive pin 50 has not moved remaining in its angular position corresponding to the state I of FIG. 8C .
Le mécanisme d'actionnement automatisé 30 est prêt pour un nouveau cycle de fonctionnement. Il permet en alimentant électriquement T électroaimant 31 de droite de faire tourner la première roue à rochet 51 dans le sens inverse R' pour changer d'état l'appareil de coupure 1 et le ramener à son état 0, puis en activant toujours l' électroaimant 31 de droite de changer à nouveau son état pour le passer de l'état 0 à l'état II, tel qu'illustré par la figure 8E.The automated actuation mechanism 30 is ready for a new cycle of operation. It makes it possible by electrically feeding electromagnet 31 on the right to turn the first ratchet wheel 51 in the opposite direction R 'to change the state of the breaking device 1 and bring it back to its state 0, then still activating it. electromagnet 31 on the right to change its state again from state 0 to state II, as shown in FIG. 8E.
Les phases de fonctionnement décrites ci-dessus s'effectuent dans un laps de temps très court, de l'ordre de quelques millisecondes, le temps d'une impulsion électrique. Ce mécanisme d'actionnement automatisé 30 permet d'obtenir ainsi une commutation électrique dans les modules de coupure 2 très rapide et de s'affranchir du système à action brusque. Bien entendu, les électroaimants 31 sont commandés sélectivement par une carte électronique (non représentée) intégrée dans le boîtier 11 et asservie par les moyens de pilotage en fonction de la position angulaire de la broche d'entraînement 50. Ce module de commande 10 permet donc à l'aide d'une commande monostable par impulsion de commander un appareil de coupure 1 à trois positions stables : I-O-Et ou I-I+II-ÏÏ, ou plus. H permet aussi de commander un appareil de coupure 1 à deux positions stables : 1-0 ou I-II. Le même résultat peut être obtenu avec un module de commande 10 équipé d'un seul électroaimant 31. Dans ce cas, la première roue à rochet 51 est pourvue de dents 51' réparties régulièrement sur toute sa périphérie pour coopérer avec un seul premier cliquet 43, de manière à faire tourner la broche d'entraînement 50 dans le même sens de rotation.The operating phases described above are carried out in a very short period of time, of the order of a few milliseconds, the time of an electrical pulse. This automated actuation mechanism 30 thus makes it possible to obtain electrical switching in the very fast breaking modules 2 and to get rid of of the snap system. Of course, the electromagnets 31 are selectively controlled by an electronic card (not shown) integrated in the housing 11 and controlled by the control means as a function of the angular position of the drive pin 50. This control module 10 thus allows using a monostable pulse control to control a switchgear 1 at three stable positions: IO-I or I-I + II-II, or more. H also makes it possible to control a switchgear 1 with two stable positions: 1-0 or I-II. The same result can be obtained with a control module 10 equipped with a single electromagnet 31. In this case, the first ratchet wheel 51 is provided with teeth 51 'distributed evenly over its entire periphery to cooperate with a single first pawl 43 , so as to rotate the drive pin 50 in the same direction of rotation.
Le fonctionnement de ce module de commande 10 est détaillé à présent en référence aux figures HA-C qui illustrent le mécanisme d'actionnement manuel 60. Elles montrent la seconde roue à rochet 68, les seconds cliquets 67, leur ressort à lame 69, le manchon 63 et les secondes cames 65 du pignon de sortie 62, et en traits interrompus, la broche d'entraînement 50. Elles ne montrent pas le pignon d'entrée 61, ni la clé 14 pour le faire tourner. Le fonctionnement est également décrit en référence aux figures 10A-C qui illustrent le ressort de torsion 66 du système à action brusque. Ces figures montrent par transparence le manchon 63 et ses nervures axiales intérieures 64, le ressort de torsion 66 et ses branches 66a, 66b, la broche d'entraînement 50, sa partie discale 54 et sa paroi radiale 55.The operation of this control module 10 is now detailed with reference to Figures HA-C which illustrate the manual actuating mechanism 60. They show the second ratchet wheel 68, the second pawls 67, their leaf spring 69, the sleeve 63 and the second cams 65 of the output gear 62, and in phantom, the drive pin 50. They do not show the input pinion 61, nor the key 14 to turn it. The operation is also described with reference to Figs. 10A-C which illustrate the torsion spring 66 of the snap action system. These figures show by transparency the sleeve 63 and its internal axial ribs 64, the torsion spring 66 and its branches 66a, 66b, the drive pin 50, its disc portion 54 and its radial wall 55.
Si le mécanisme d'actionnement automatisé 30 n'est pas en fonction c'est-à-dire que le module de commande 10 est en mode manuel, les premiers cliquets 43 sont en position passive, étant maintenus écartés de la première roue à rochet 51 par la lèvre de retenue 71 de la paroi intermédiaire 70. Dans ce cas, la broche d'entraînement 50 peut tourner librement sans solliciter le pignon moteur 40 ni la crémaillère 35. Aux figures 10A et HA, le mécanisme d'actionnement manuel 60 est au repos et l'appareil de coupure 1 est à l'état 0 : le pignon de sortie 62 est dans sa position centrale, les seconds cliquets 67 sont en appui contre le manchon 63 sous l'action de leur ressort à lame 69, les seconds cliquets 67 du coté gauche étant en prise avec deux dents 68' de la seconde roue à rochet 68 bloquant sa rotation dans les deux sens, le ressort de torsion 66 n'est pas sollicité, la broche d'entraînement 50 est immobile.If the automated actuation mechanism 30 is not in operation, that is to say that the control module 10 is in manual mode, the first pawls 43 are in the passive position, being kept away from the first ratchet wheel 51 by the retaining lip 71 of the intermediate wall 70. In this case, the drive pin 50 can rotate freely without stressing the motor pinion 40 or the rack 35. In FIGS. 10A and HA, the manual actuating mechanism 60 is at rest and the breaking device 1 is in the 0 state: the output gear 62 is in its central position, the second pawls 67 bear against the sleeve 63 under the action of their leaf spring 69, the second pawls 67 on the left side being engaged with two teeth 68 'of the second ratchet wheel 68 blocking its rotation in both directions, the torsion spring 66 n' is not requested, the drive pin 50 is stationary.
A la figure 10B, le mécanisme d'actionnement manuel 60 est au travail et l'appareil de coupure 1 est toujours à l'état 0 : le pignon de sortie 62 a pivoté vers la gauche dans le sens anti-horaire R' d'un angle d'environ 60° sous l'action manuelle d'un opérateur sur la clé 14 pour tourner le pignon d'entrée 61 d'un angle correspondant, la seconde roue à rochet 68 reste immobilisée par les seconds cliquets 67 en prise avec ses dents 68', le ressort de torsion 66 est comprimé, sa branche 66a étant emmenée par la nervure axiale 64 du manchon 63, l'autre branche 66b restant bloquée dans le logement 55' de la paroi radiale 55 de la broche d'entraînement 50 qui reste immobile.In FIG. 10B, the manual operating mechanism 60 is at work and the cut-off device 1 is always in state 0: the output gear 62 has rotated to the left in the counter-clockwise direction R 'd' an angle of about 60 ° under the manual action of an operator on the key 14 to turn the input gear 61 by a corresponding angle, the second ratchet wheel 68 remains immobilized by the second pawls 67 engaged with its teeth 68 ', the torsion spring 66 is compressed, its branch 66a being led by the axial rib 64 of the sleeve 63, the other branch 66b remaining locked in the housing 55' of the radial wall 55 of the drive pin 50 who remains motionless.
A la figure 1 IB, le mécanisme d'actionnement manuel 60 est au travail et l'appareil de coupure 1 a changé d'état et est passé de l'état 0 à l'état II : les secondes cames 65 du pignon de sortie 62 ont soulevé les seconds cliquets 67 qui ont libéré la roue à rochet 68 autorisant la rotation de la broche d'entraînement 50 dans le même sens R' sous l'effet du ressort de torsion 66. Ce mouvement de rotation brusque est transmis directement à l'axe de commande de l'appareil de coupure 1 qui commute rapidement. Les seconds cliquets 67 du coté droit sont maintenant en prise avec les dents 68' de la seconde roue à rochet 68, bloquant sa rotation dans les deux sens, pour permettre de commuter l'appareil de coupure de l'état II à l'état 0 en tournant le pignon de sortie 62 dans le sens inverse R par le biais de la clé 14 et du pignon d'entrée 61. Dans ce cas, le ressort de torsion 66 est à nouveau sollicité pour obtenir une commutation rapide. Ces étapes ne sont pas illustrées.In FIG. 1IB, the manual actuating mechanism 60 is at work and the switching device 1 has changed state and has gone from state 0 to state II: the second cams 65 of the output gear 62 have raised the second pawls 67 which have released the ratchet wheel 68 allowing the rotation of the drive pin 50 in the same direction R 'under the effect of the torsion spring 66. This sudden rotation movement is transmitted directly to the control axis of the switching device 1 which switches quickly. The second ratchets 67 on the right side are now engaged with the teeth 68 'of the second ratchet wheel 68, blocking its rotation in both directions, to allow the switching device of the state II to be switched to the state 0 by turning the output gear 62 in the opposite direction R by means of the key 14 and the pinion In this case, the torsion spring 66 is again biased to obtain rapid switching. These steps are not illustrated.
A la figure 1OC, le mécanisme d'actionnement manuel 60 est au travail et l'appareil de coupure 1 est à l'état 0 : le pignon de sortie 62 a pivoté vers la droite dans le sens horaire R d'un angle d'environ 60° sous l'action manuelle d'un opérateur sur la cléIn FIG. 10C, the manual operating mechanism 60 is at work and the breaking device 1 is in the state 0: the output gear 62 has pivoted to the right in the clockwise direction R by an angle of about 60 ° under the manual action of an operator on the key

A la figure 1 IC, le mécanisme d'actionnement manuel 60 est au travail et l'appareil de coupure 1 a changé d'état et est passé de l'état 0 à l'état I : les secondes cames 65 du pignon de sortie 62 ont soulevé les seconds cliquets 67 qui ont libéré la roue à rochet 68 autorisant la rotation de la broche d'entraînement 50 dans le même sens R sous l'effet du ressort de torsion 66. Ce mouvement de rotation brusque est transmis directement à l'axe de commande de l'appareil de coupure 1 qui commute rapidement. Les seconds cliquets 67 du coté droit sont à nouveau en prise avec les dents 68' de la seconde roue à rochet 68, bloquant sa rotation dans les deux sens, pour permettre de commuter l'appareil de coupure de l'état I à l'état 0 en tournant le pignon de sortie 62 dans le sens inverse R' par le biais de la clé 14 et du pignon d'entrée 61. Dans ce cas, le ressort de torsion 66 est à nouveau sollicité pour obtenir une commutation rapide. Ces étapes ne sont pas illustrées.In FIG. 1 IC, the manual actuating mechanism 60 is at work and the switching device 1 has changed state and has gone from state 0 to state I: the second cams 65 of the output gear 62 have raised the second pawls 67 which have released the ratchet wheel 68 allowing the rotation of the drive pin 50 in the same direction R under the effect of the torsion spring 66. This sudden rotation movement is transmitted directly to the ratchet control axis of the switching device 1 which switches quickly. The second pawls 67 on the right side are again engaged with the teeth 68 'of the second ratchet wheel 68, blocking its rotation in both directions, to allow switching the switchgear from the state I to the state 0 by turning the output gear 62 in the opposite direction R 'through the key 14 and the input gear 61. In this case, the torsion spring 66 is again biased to obtain a fast switching. These steps are not illustrated.
