Pour un appareil devant fonctionner en mode télérupteur, le circuit électronique de commande comporte des seconds moyens auxquels sont appliqués les signaux de télécommande, les signaux d'horloge et les signaux représentatifs de la position des contacts, et produisant un signal prenant la valeur logique 1 lors d'un front montant du signal de télécommande, et ne passant à la valeur logique 0 qu'après une modification de la position des contacts, et une première porte ET à laquelle sont appliqués les signaux de télécommande et d'horloge, le signal de sortie des premiers moyens et, sur une 4ème entrée, le signal de sortie des seconds moyens, le signal de sortie de la première porte ET étant constitué par lesdites premières et secondes impulsions.For a device having to operate in remote control mode, the electronic control circuit comprises second means to which the remote control signals, the clock signals and the signals representative of the position of the contacts are applied, and producing a signal taking the logic value 1 during a rising edge of the remote control signal, and passing to logic value 0 only after a modification of the position of the contacts, and a first AND gate to which the remote control and clock signals are applied, the signal of the first means and, on a 4th input, the output of the second means, the output of the first AND gate being formed by said first and second pulses.

Si l'appareil fonctionne en mode contacteur, lesdits premiers moyens produisent un second signal de sortie de valeur logique 1 jusqu'au premier front descendant du signal d'horloge suivant un front descendant du signal de commande, prenant la valeur logique 0 pendant ladite première durée prédéterminée et de nouveau la valeur logique 1 pendant ladite seconde durée prédéterminée, le circuit électronique de commande comportant une seconde porte ET à laquelle sont appliqués les signaux de télécommande et d'horloge, le premier signal de sortie desdits premiers moyens et, sur une 4ème entrée, un signal complémentaire du signal représentatif de la position des contacts, et une troisième porte ET à laquelle sont appliqués les signaux d'horloge, un signal complémentaire du signal de télécommande, le second signal de sortie desdits premiers moyens, et, sur une 4ème entrée, le signal représentatif de la position des contacts, les signaux de sortie des seconde et troisième porte ET étant appliqués aux entrées d'une porte OU dont le signal de sortie est formé par lesdites premières et secondes impulsions.If the device operates in contactor mode, said first means produce a second output signal of logic value 1 until the first falling edge of the clock signal following a falling edge of the control signal, taking the logic value 0 during said first predetermined duration and again the logic value 1 during said second predetermined duration, the electronic control circuit comprising a second AND gate to which the remote control and clock signals are applied, the first output signal of said first means and, on a 4th input, a signal complementary to the signal representative of the position of the contacts, and a third AND gate to which the clock signals are applied, a signal complementary to the remote control signal, the second output signal of said first means, and, on a 4th input, the signal representative of the position of the contacts, the output signals of the second and third th AND gate being applied to the inputs of an OR gate whose output signal is formed by said first and second pulses.

Pour un appareil de coupure dans lequel l'entrée contacteur peut également servir d'entrée télérupteur, un sélecteur fournissant auxdits seconds moyens un signal de valeur 1 pour le fonctionnement en contacteur et un signal de valeur 0 pour le fonctionnement en télérupteur, les signaux de sortie desdits seconds moyens appliqués à la 4ème entrée de la seconde porte ET sont, en fonction contacteur, dérivés du signal complémentaire du signal représentatif de la position des contacts et lesdits seconds moyens appliquent sur la 4ème entrée de la troisième porte ET, un signal de valeur 0 en fonction télérupteur et dérivé du signal représentatif de la position des contacts en fonction contacteur.For a breaking device in which the contactor input can also serve as a remote control input, a selector providing said second means with a signal of value 1 for operation in contactor and a signal of value 0 for operation in remote control, the signals of output of said second means applied to the 4th input of the second AND gate are, in contactor function, derived from the signal complementary to the signal representative of the position of the contacts and said second means apply to the 4th input of the third AND gate, a signal of value 0 according to the remote control function and derived from the signal representative of the position of the contacts in contactor function.

Sur les figures 1 et 2, un appareil de coupure de courant télécommandé, représenté par le repère général 10 comporte deux blocs unipolaires de coupure 12, 14 ou pôles, accolés à un bloc de télécommande 16 pour constituer un système modulaire bipolaire de commande à distance. Chaque pôle 12,14 est logé dans un boîtier individuel en matière isolante moulée et renferme un mécanisme de coupure du type décrit en détail dans le brevet français n°2.535.520. Les deux pôles 12,14 constituent le circuit de puissance et sont dotés de deux bornes d'arrivée 18,20 raccordées au réseau de distribution à basse tension par deux lignes d'alimentation 22,24, et de deux bornes de départ 26,28 connectées à une charge (non représentée) par deux conducteurs de liaison 30,32. Les pôles 12,14 peuvent bien entendu être rassemblés dans un boîtier unique bipolaire. Trois ou quatre pôles identiques peuvent également être juxtaposés pour former un appareil de coupure tripolaire ou tétrapolaire.In FIGS. 1 and 2, a remote-controlled power cut device, represented by the general reference 10 comprises two unipolar cut-off blocks 12, 14 or poles, attached to a remote control block 16 to constitute a modular bipolar remote control system. Each pole 12,14 is housed in an individual casing made of molded insulating material and contains a cut-off mechanism of the type described in detail in French Patent No. 2,535,520. The two poles 12,14 constitute the power circuit and are provided with two incoming terminals 18,20 connected to the low-voltage distribution network by two supply lines 22,24, and two starting terminals 26,28 connected to a load (not shown) by two connecting conductors 30.32. The poles 12, 14 can of course be brought together in a single bipolar box. Three or four identical poles can also be juxtaposed to form a three-pole or four-pole breaking device.

Chaque pôle 12,14 comporte un contact principal mobile 33 bistable actionné entre les deux positions de fermeture et d'ouverture de l'appareil. Le bloc de télécommande 16 est équipé d'un mécanisme de télécommande 34 (figure 2) destiné à assurer le basculement des contacts mobiles 33 de la position de fermeture vers la position d'ouverture et inversement, à la suite d'un ordre de télécommande appliqué à un actionneur électromagnétique à électro-aimant 36. A l'intérieur de chaque pôle de coupure 12,14 est agencé un déclencheur magnétothermique associé à un mécanisme de déclenchement automatique 38 coopérant avec le contact mobile 33 pour le déplacer vers la position d'ouverture en cas de surcharge et/ou de défaut, et le maintenir dans cette position indépendamment de la position du mécanisme de télécommande 16 tant que le mécanisme de déclenchement 38 se trouve en position déclenchée. Une remise en service nécessite un actionnement d'une manette 40 de réarmement manuel du mécanisme de déclenchement 38 pour autoriser en position armée de ce dernier une fermeture télécommandée de l'appareil par le bloc de télécommande 16.Each pole 12,14 has a movable main contact 33 bistable actuated between the two closed and open positions of the device. The remote control unit 16 is equipped with a remote control mechanism 34 (FIG. 2) intended to ensure the tilting of the movable contacts 33 from the closed position to the open position and vice versa, following a remote control command. applied to an electromagnetic actuator with electromagnet 36. Inside each cut-off pole 12,14 is arranged a magneto-thermal trip device associated with an automatic trip mechanism 38 cooperating with the movable contact 33 to move it towards the position of opening in the event of overload and / or fault, and maintain it in this position regardless of the position of the remote control mechanism 16 as long as the trigger mechanism 38 is in the triggered position. A return to service requires actuation of a manual reset lever 40 of the trigger mechanism 38 to authorize in the armed position of the latter a remote-controlled closure of the device by the remote control unit 16.

L'électro-aimant 36 du bloc de télécommande 16 est pourvu d'un noyau plongeur 42 agissant sur un levier pivotant 44 articulé à son extrémité opposée sur un point fixe 46 du boîtier 48 isolant. Le levier 44 porte un poussoir 50 coopérant mécaniquement avec une bascule 52 montée à rotation limitée sur un axe 54 fixe, et avec un ressort 56 de rappel en forme de lame. La bascule 52 est accouplée par un embiellage 58 à une manette 60 pivotante constituant un organe de commande de secours destiné à ouvrir ou fermer manuellement l'appareil 10. La manette 60 de commande manuelle est reliée d'autre part à un bras 62 pouvant s'enfourcher dans un balancier (non représenté) agissant sur les contacts 33 mobiles des pôles 12,14, manière à solidariser mécaniquement le balancier et la bascule 52.The electromagnet 36 of the remote control unit 16 is provided with a plunger core 42 acting on a pivoting lever 44 articulated at its opposite end on a fixed point 46 of the insulating housing 48. The lever 44 carries a pusher 50 cooperating mechanically with a rocker 52 mounted with limited rotation on a fixed axis 54, and with a return spring 56 in the form of a blade. The rocker 52 is coupled by a connecting rod 58 to a pivoting lever 60 constituting an emergency control member intended to manually open or close the device 10. The lever 60 for manual control is also connected to an arm 62 which can 'straddle in a balance (not shown) acting on the movable contacts 33 of the poles 12,14, so as to mechanically secure the balance and the rocker 52.

Le fonctionnement d'un tel appareil de coupure est décrit plus en détail dans le EP-A- 0 108 678 et dans le brevet français n° 2.579.821 et peut être résumé comme suit:The operation of such a cut-off device is described in more detail in EP-A-0 108 678 and in French patent No. 2,579,821 and can be summarized as follows:

En position armée de la manette 40 de réarmement, l'ouverture et la fermeture des contacts des pôles 12,14 peuvent être soit pilotées manuellement par la manette 60 de secours, soit télécommandées par excitation de l'électro-aimant 36 du bloc de télécommande 16. A chaque ordre appliqué à l'électro-aimant 36 s'opère un changement d'état de la bascule 52, et le mécanisme de déclenchement 38 reste inactif lors de ces manoeuvres télécommandées.In the armed position of the reset lever 40, the opening and closing of the pole contacts 12, 14 can either be controlled manually by the backup handle 60, or remote-controlled by energizing the electromagnet 36 of the remote control unit. 16. At each command applied to the electromagnet 36 there is a change of state of the flip-flop 52, and the trigger mechanism 38 remains inactive during these remote-controlled maneuvers.

En cas de défaut, le mécanisme de déclenchement 38 provoque l'ouverture des contacts des pôles 12,14, et le déplacement de la manette 40 de réarmement vers la position déclenchée. Les contacts mobiles 33 sont maintenus en position d'ouverture indépendamment de tout ordre de télécommande. On remarque que cette position déclenchée de la manette 40 constitue une indication fiable de l'ouverture des contacts. Une remise en service de l'appareil 10 nécessite une intervention manuelle de réarmement de la manette 40 en position armée, l'appareil étant alors prêt pour de nouvelles manoeuvres pilotées par le mécanisme de télécommande 34.In the event of a fault, the triggering mechanism 38 causes the opening of the pole contacts 12, 14, and the displacement of the reset lever 40 towards the triggered position. The movable contacts 33 are maintained in the open position independently of any remote control command. It is noted that this triggered position of the lever 40 constitutes a reliable indication of the opening of the contacts. Putting the device 10 back into service requires manual intervention to reset the lever 40 in the armed position, the device then being ready for new maneuvers controlled by the remote control mechanism 34.

Le bloc de télécommande 16 comporte quatre bornes de connexion CT,TL,P et N en liaison interne avec un circuit électronique 39 de commande de l'électro-aimant 36. Les deux bornes P et N sont des bornes d'alimentation reliées par des conducteurs 68,70 externes à une source de tension 72 alternative ou continue, par exemple 220 Volts. La borne d'entrée TL est affectée à une première commande par impulsions du type télérupteur, le signal impulsionnel étant engendré par l'actionnement d'un premier interrupteur ou contact monostable, notamment un bouton-poussoir 74, interconnecté entre la borne TL et le conducteur 68. La borne d'entrée CT est utilisée pour une deuxième commande mixte, qui dépend de la position d'un sélecteur S. Un deuxième contact 76 de commande ou interrupteur est connecté électriquement entre la borne CT et le conducteur 68. On remarque que les deux bornes d'entrée CT et TL sont reliées par leurs contacts 76, 74 respectifs à un même potentiel, qui est celui de la borne d'alimentation P, ou selon une variante, celui de l'autre borne d'alimentation N. Dans le cas d'un réseau de distribution à 220 Volts, les conducteurs 68,70 pourraient être raccordés directement aux lignes d'alimentation 22,24 des pôles 12,14, autorisant la suppression de la source de tension 72.The remote control unit 16 comprises four connection terminals CT, TL, P and N in internal connection with an electronic circuit 39 for controlling the electromagnet 36. The two terminals P and N are supply terminals connected by conductors 68.70 external to an AC or DC voltage source 72, for example 220 Volts. The TL input terminal is assigned to a first impulse command of the remote control type, the impulse signal being generated by the actuation of a first monostable switch or contact, in particular a push button 74, interconnected between the TL terminal and the conductor 68. The CT input terminal is used for a second mixed control, which depends on the position of a selector S. A second control contact 76 or switch is electrically connected between the CT terminal and conductor 68. Note that the two input terminals CT and TL are connected by their respective contacts 76, 74 to the same potential, which is that of the supply terminal P, or according to a variant, that of the other supply terminal N In the case of a 220 Volt distribution network, the conductors 68.70 could be connected directly to the supply lines 22.24 of the poles 12.14, authorizing the removal of the voltage source 72.

Dans le bloc de télécommande 16, représenté schématiquement sur la figure 3, la bobine 36 de l'électro-aimant est connectée à la source d'alimentation (P,N) par l'intermédiaire d'un interrupteur statique 37. Lorsque la tension d'alimentation est une tension alternative on utilise de préférence un thyristor comme représenté sur la figure. Bien entendu, il est également possible d'utiliser tout autre type d'interrupteur statique, par exemple un transistor à effet de champ de puissance de type MOSFET, la tension d'alimentation qui lui est appliquée étant alors redressée si nécessaire.In the remote control unit 16, shown diagrammatically in FIG. 3, the coil 36 of the electromagnet is connected to the power source (P, N) by means of a static switch 37. When the voltage power supply is an AC voltage, preferably a thyristor as shown in the figure. Of course, it is also possible to use any other type of static switch, for example a power field effect transistor of the MOSFET type, the supply voltage which is applied thereto then being rectified if necessary.

Le circuit électronique de commande 39 est destiné à appliquer sur l'électrode de commande de l'interrupteur statique 37 les signaux appropriés en fonction de la position des contacts mobiles et des signaux de télécommande qui lui sont appliqués sur les entrées TL et CT. Il est également alimenté par les bornes P et N, un bloc d'alimentation approprié (non représenté) incorporé dans le circuit 39 lui fournissant les tensions continues nécessaires.The electronic control circuit 39 is intended to apply to the control electrode of the static switch 37 the appropriate signals as a function of the position of the movable contacts and of the remote control signals which are applied to it on the TL and CT inputs. It is also supplied by terminals P and N, an appropriate power supply unit (not shown) incorporated in circuit 39 providing it with the necessary DC voltages.

Le fonctionnement du bloc de télécommande 16 s'effectue de la manière suivante:The operation of the remote control unit 16 is carried out as follows:

En position armée de la manette 40 de réarmement, chaque ordre de télécommande délivré par le circuit électronique de commande 39 à l'interrupteur statique 37 provoque l'excitation de l'électro-aimant 36 et un changement d'état des contacts principaux mobiles 33 des pôles 12,14. Cet ordre de télécommande peut parvenir soit de la première commande par implusions associée à la borne d'entrée TL (fermeture du bouton-poussoir 74), soit de la deuxième commande affectable selon l'état du sélecteur S, et associée à la borne d'entrée CT (fermeture du contact 76).In the armed position of the reset lever 40, each remote control command issued by the electronic control circuit 39 to the static switch 37 causes the electromagnet 36 to be excited and a change in state of the movable main contacts 33 poles 12.14. This remote control command can come either from the first command by implusions associated with the input terminal TL (closing of the push button 74), or from the second assignable command according to the state of the selector S, and associated with the terminal d 'CT input (contact 76 closed).

La première commande correspond à un fonctionnement de l'appareil 10 en mode télérupteur, chaque impulsion appliquée à la borne d'entrée TL (figure 4a) provoquant un changement d'état des contacts principaux 33 (figures 4c et 4d).The first command corresponds to an operation of the apparatus 10 in remote control mode, each pulse applied to the input terminal TL (FIG. 4a) causing a change of state of the main contacts 33 (FIGS. 4c and 4d).

La deuxième commande correspond à un fonctionnement en mode contacteur de l'appareil 10 lorsque le plot de contact du sélecteur S se trouve en position enfichée (S=1), comme représenté sur la figure 4. Le contact 76 peut être actionné par une horloge, minuterie ou automate (non représentés), de manière à appliquer à la borne d'entrée CT des créneaux de commande, chaque créneau ayant une largeur généralement supérieure à celle des impulsions de la première commande (voir figure 4). L'ordre de commande à la sortie du circuit électronique de commande 39 (figure 4c) dépend de l'état du contact 76 engendrant le créneau à la borne d'entrée CT, et de l'état d'un détecteur 41 représentant la position des contacts principaux mobiles 33. Un tel détecteur peut, de manière connue, être formé par un relais REED dont le contact de commande est actionné par un aimant permanent solidaire d'un organe de transmission du mouvement des contacts principaux mobiles, ce détecteur étant disposé à l'intérieur du bloc de télécommande 16 (figure 3). Le circuit électronique de commande ne fournit un ordre de changement de position des contacts à l'interrupteur statique 37 que si les contacts principaux 33 sont ouverts lors de la fermeture du contact de commande 76, ou si les contacts 33 sont fermés lors de l'ouverture du contact 76. Dans le premier cas, la fermeture du contact 76 engendre un front montant du créneau qui entraîne la fermeture des contacts principaux 33. Dans le deuxième cas, l'ouverture du contact 76 engendre un front descendant du créneau qui pilote l'ouverture des contacts principaux 33. La fermeture du contact 76 en position fermé des contacts principaux 33, et l'ouverture du contact 76 en position ouvert des contacts principaux 33 n'engendrent aucun changement d'état de l'appareil 10 (figures 4b,4c,4d).The second command corresponds to an operation in contactor mode of the device 10 when the contact pad of the selector S is in the plugged-in position (S = 1), as shown in FIG. 4. The contact 76 can be actuated by a clock , timer or automaton (not shown), so as to apply control slots to the CT input terminal, each slot having a width generally greater than that of the pulses of the first control (see FIG. 4). The control order at the output of the electronic control circuit 39 (FIG. 4c) depends on the state of the contact 76 generating the slot at the input terminal CT, and on the state of a detector 41 representing the position movable main contacts 33. Such a detector can, in known manner, be formed by a relay REED, the control contact of which is actuated by a permanent magnet secured to a member for transmitting the movement of the movable main contacts, this detector being placed inside the remote control unit 16 (FIG. 3). The electronic control circuit provides an order to change the position of the contacts at the static switch 37 only if the main contacts 33 are open when the control contact 76 is closed, or if the contacts 33 are closed during the opening of the contact 76. In the first case, the closing of the contact 76 generates a rising edge of the niche which causes the closing of the main contacts 33. In the second case, the opening of the contact 76 generates a falling edge of the niche which controls the opening of the main contacts 33. The closing of the contact 76 in the closed position of the main contacts 33, and the opening of the contact 76 in the open position of the main contacts 33 does not cause any change in the state of the device 10 (FIGS. 4b , 4c, 4d).

En position inactive (S=0) du sélecteur la deuxième borne d'entrée (76) correspond à une entrée impulsionnelle découplée de la première commande, de manière à autoriser une commande du type télérupteur pilote.In the inactive position (S = 0) of the selector, the second input terminal (76) corresponds to an impulse input decoupled from the first command, so as to authorize a command of the pilot switch type.

Dans le dispositif tel que décrit ci-dessus, le circuit électronique de commande 39 applique donc un signal de commande sur l'électrode de commande de l'interrupteur statique 37 lorsqu'il reçoit en entrée un signal de télécommande impliquant un changement de position du contact mobile, c'est à dire sans tenir compte de la position réelle du contact dans un fonctionnement en télérupteur et en tenant compte de cette position dans un fonctionnement en contacteur.In the device as described above, the electronic control circuit 39 therefore applies a control signal to the control electrode of the static switch 37 when it receives a remote control signal as input implying a change in position of the movable contact, that is to say without taking account of the actual position of the contact in operation as a remote control switch and taking account of this position in operation as a contactor.

Selon l'invention, le circuit électronique de commande 39 surveille la position du contact mobile pendant un temps prédéterminé après application du signal de commande de changement de position, sous forme d'une première impulsion, sur l'électrode de commande et applique une seconde impulsion sur cette électrode si le changement de position désiré du contact mobile n'a pas eu lieu.According to the invention, the electronic control circuit 39 monitors the position of the movable contact for a predetermined time after application of the position change control signal, in the form of a first pulse, to the control electrode and applies a second impulse on this electrode if the desired change of position of the movable contact has not taken place.

Le schéma représenté sur la figure 5 correspond à la partie associée à la voie télérupteur d'un circuit électronique de commande 39 d'un appareil selon les figures 1 à 3, mettant en oeuvre l'invention.The diagram shown in FIG. 5 corresponds to the part associated with the remote control path of an electronic control circuit 39 of an apparatus according to FIGS. 1 to 3, implementing the invention.

La voie représentée sur la figure 5 comporte trois entrées. Sur la première entrée sont appliqués les signaux A de télécommande (figure 6c) de type télérupteur (TL). La seconde entrée reçoit un signal H d'horloge (figure 6a), à la fréquence du secteur, produit par un circuit d'horloge (non représenté) de type classique faisant partie du circuit électronique de commande 39 et synchronisé sur le secteur. Ainsi, lorsque la bobine de l'électro-aimant est alimentée par le secteur, le circuit électronique de commande pourra produire des impulsions synchronisées avec l'alimentation de la bobine. La troisième entrée reçoit le signal B représentatif de la position des contacts mobiles, produit par le détecteur de position 41 associé aux contacts mobiles. Le signal B prend la valeur 1 lorsque les contacts sont en position de fermeture et la valeur 0 lorqu'ils sont en position d'ouverture.The channel shown in Figure 5 has three inputs. The remote control signals A (Figure 6c) of the remote control type (TL) are applied to the first input. The second input receives a clock signal H (FIG. 6a), at the sector frequency, produced by a clock circuit (not shown) of the conventional type forming part of the electronic control circuit 39 and synchronized with the sector. Thus, when the coil of the electromagnet is supplied by the sector, the electronic control circuit can produce pulses synchronized with the supply of the coil. The third input receives the signal B representative of the position of the mobile contacts, produced by the position detector 41 associated with the mobile contacts. Signal B takes the value 1 when the contacts are in the closed position and the value 0 when they are in the open position.

Le signal A de télécommande est appliqué à l'entrée D1 d'une première bascule bistable 78, de type D, dont l'entrée horloge reçoit le signal H (figure 6b) complémentaire du signal d'horloge H. Le signal Q1 (figure 6d) de sortie de la première bascule est appliqué à l'entrée D2 d'une seconde bascule 80, de même type, recevant également le signal H sur son entrée horloge. Le signal Q2 (figure 6e) de sortie de la seconde bascule est lui même appliqué à l'entrée D3 d'une troisième bascule 82, de même type, recevant le signal H sur son entrée horloge.The remote control signal A is applied to the input D1 of a first flip-flop 78, of type D, the clock input of which receives the signal H (figure 6b) complementary to the clock signal H. The signal Q1 (figure 6d) of output of the first flip-flop is applied to the input D2 of a second flip-flop 80, of the same type, also receiving the signal H on its clock input. The output signal Q2 (FIG. 6e) of the second flip-flop is itself applied to the input D3 of a third flip-flop 82, of the same type, receiving the signal H on its clock input.

Les signaux de sortie Q2 et Q3 (figures 6g et 6h) des 2ème et 3ème bascules sont appliqués aux deux entrées d'un circuit OU EXCLUSIF 84, qui fournit en sortie un signal C (figure 6i). Ce signal C, dont la durée est constante et égale, dans le mode de réalisation préférentiel représenté, à une période du signal d'horloge, prend la valeur 1 après chaque front, montant ou descendant, du signal de télécommande A. La durée (t1-t3; t2-t4) séparant le front du signal A du passage à 1 du signal C est comprise entre une et deux périodes d'horloge.The output signals Q2 and Q3 (Figures 6g and 6h) of the 2nd and 3rd flip-flops are applied to the two inputs of an EXCLUSIVE OR circuit 84, which outputs a signal C (Figure 6i). This signal C, the duration of which is constant and equal, in the preferred embodiment shown, to a period of the clock signal, takes the value 1 after each rising or falling edge of the remote control signal A. The duration (t1 -t3; t2-t4) separating the edge of signal A from the transition to 1 of signal C is between one and two clock periods.

Ce signal C et le signal Q1 de sortie de la 1ère bascule sont appliqués aux deux entrées d'un circuit OU 86, dont le signal de sortie D est représenté sur la figure 6k.This signal C and the signal Q1 output of the 1st flip-flop are applied to the two inputs of an OR circuit 86, the output signal D of which is represented in FIG. 6k.

Le signal B (figure 61), de sortie du détecteur 41 (figure 3), représentatif de la position des contacts mobiles est appliqué à l'entrée D4 d'une 4ème bascule 88, de type D, recevant sur son horloge le signal H. Le signal de sortie Q4 de la 4ème bascule est appliqué à l'entrée D5 d'une 5ème bascule 90, de type D, sur l'entrée d'horloge de laquelle est appliqué le signal de télécommande A. Les signaux Q4 et Q5 (figures 6m et 6n) de sortie des 4ème et 5ème bascules sont appliqués aux deux entrées d'un circuit OU EXCLUSIF 92, dont le signal de sortie E est représenté sur la figure 6o.The signal B (figure 61), output from the detector 41 (figure 3), representative of the position of the movable contacts is applied to the input D4 of a 4th flip-flop 88, of type D, receiving on its clock the signal H . The output signal Q4 of the 4th flip-flop is applied to the D5 input of a 5th flip-flop 90, of type D, on the clock input of which the remote control signal A is applied. The signals Q4 and Q5 (Figures 6m and 6n) output from the 4th and 5th flip-flops are applied to the two inputs of an EXCLUSIVE OR circuit 92, the output signal E of which is shown in Figure 6o.

Dans la voie télérupteur représentée sur la figure 5, le signal E prend la valeur 1 à chaque front montant (instants t1 et t2) du signal A de télécommande, quelle que soit la position des contacts à cet instant, c'est à dire indépendamment de la valeur du signal B. Puis il repasse à O au premier front montant du signal H suivant le changement de position des contacts, les signaux de sortie Q4 et Q4 de la bascule 88 changeant alors de valeur.In the remote control switch channel shown in FIG. 5, the signal E takes the value 1 at each rising edge (times t1 and t2) of the remote control signal A, whatever the position of the contacts at this instant, that is to say independently of the value of signal B. Then it returns to O at the first rising edge of the signal H following the change of position of the contacts, the output signals Q4 and Q4 of flip-flop 88 then changing value.

Ainsi le passage à 0 du signal E après un front montant du signal A de télécommande est représentatif d'un changement de position des contacts mobiles suivant un front montant du signal de télécommande A.Thus the change to 0 of the signal E after a rising edge of the remote control signal A is representative of a change in position of the movable contacts along a rising edge of the remote control signal A.

Une porte ET 94 recevant sur ses entrées les signaux D, A, H et E fournit alors en sortie un signal F (figure 6p), comportant une première impulsion après un front montant du signal A. Sur la figure 6, on a représenté les signaux B, Q4, Q5, E et F obtenus d'une part (partie gauche, entre t1 et t2) lorsqu'une première impulsion F1 provoque un changement de position du contact mobile avant le 1er front montant du signal C (t3) suivant le front montant correspondant (t1) du signal A de télécommande, et d'autre part (partie droite) lorsque le changement de position du contact mobile n'a pas lieu avant le front montant du signal C (t4) suivant le front montant correspondant (t2) du signal A.An AND gate 94 receiving on its inputs the signals D, A, H and E then outputs a signal F (FIG. 6p), comprising a first pulse after a rising edge of signal A. In FIG. 6, the signals B are shown, Q4 , Q5 , E and F obtained on the one hand (left part, between t1 and t2) when a first pulse F1 causes a change in position of the movable contact before the 1st rising edge of signal C (t3) along the corresponding rising edge (t1 ) of the remote control signal A, and on the other hand (right part) when the position of the movable contact does not change before the rising edge of the signal C (t4) following the corresponding rising edge (t2) of the signal A .

Il ressort clairement de la figure 6 que dans le 1er cas, il n'y a pas d'autre impulsion produite sur la sortie F tant qu'un nouveau front montant du signal A n'est pas appliqué au circuit. Par contre, dans le second cas, le signal E étant toujours à la valeur 1 pendant la période suivant le temps t4 où les signaux C et D repassent à la valeur 1 pour une période d'horloge, une seconde impulsion (F′2) est alors produite sur la sortie F. L'écart séparant le front descendant de la première impulsion (F2) du front montant de la seconde impulsion (F′2) est constant et égal à 1,5 période de l'horloge H, dans le mode de réalisation représenté, soit 30ms si l'horloge est synchronisée sur le secteur à 50 Hz.It is clear from FIG. 6 that in the first case, there is no other pulse produced on the output F until a new rising edge of the signal A is not applied to the circuit. On the other hand, in the second case, the signal E being always at the value 1 during the period following the time t4 where the signals C and D pass again to the value 1 for a clock period, a second pulse (F′2) is then produced on the output F. The difference separating the falling edge of the first pulse (F2) from the rising edge of the second pulse (F′2) is constant and equal to 1.5 periods of the clock H, in the embodiment shown, ie 30 ms if the clock is synchronized to the sector at 50 Hz.

Le signal F est, après calibration éventuelle, appliqué à l'électrode de commande de l'interrupteur statique, si nécessaire par l'intermédiaire d'un circuit d'adaptation (non représenté).The signal F is, after possible calibration, applied to the control electrode of the static switch, if necessary via an adaptation circuit (not shown).

Dans certains cas il peut être préférable de fournir les secondes impulsions sur une sortie séparée, de manière à permettre un traitement différent des premières et secondes impulsions, notamment du point de vue calibration. Ceci peut être réalisé simplement, comme représenté sur la figure 5, au moyen d'un circuit ET 96 recevant en entrée les signaux C et F et produisant en sortie un signal G (figure 6q) ne comportant que les secondes impulsions. Après traitement en parallèle des signaux G et F, ceux-ci sont appliqués de nouveau aux entrées d'un circuit OU (non représenté) dont la sortie est alors appliquée à l'électrode de commande de l'interrupteur statique.In some cases it may be preferable to supply the second pulses on a separate output, so as to allow different processing of the first and second pulses, in particular from the calibration point of view. This can be done simply, as shown in FIG. 5, by means of an AND circuit 96 receiving the signals C and F at the input and producing at the output a signal G (FIG. 6q) comprising only the second pulses. After parallel processing of signals G and F, these are applied again to the inputs of an OR circuit (not shown), the output of which is then applied to the control electrode of the static switch.

Il est facile de voir que s'il y n'y a pas de changement de la position des contacts mobiles, même après application d'une seconde impulsion, le signal B conserve la même valeur, de sorte que Q4 ne change pas non plus et le signal E reste à 1, jusqu'au front montant suivant du signal A de télécommande. Le signal Q4 n'ayant pas changé, le passage à 1 du signal A n'entraîne pas de modification du signal Q5, et le signal E reste également à 1. On se retrouve alors dans les mêmes conditions qu'au temps t1 ou t2.It is easy to see that if there is no change in the position of the movable contacts, even after applying a second pulse, signal B keeps the same value, so that Q4 also does not change and signal E remains at 1, until the next rising edge of signal A of the remote control. The signal Q4 not having changed, changing to 1 of signal A does not modify the signal Q5 , and the signal E also remains at 1. We then find ourselves in the same conditions as at time t1 or t2.

Le schéma représenté sur la figure 7 correspond à la partie associée à la voie contacteur d'un circuit électronique de commande d'un appareil selon les figures 1 et 2, mettant en oeuvre l'invention. Les éléments et les signaux identiques à ceux du circuit selon le figure 5 portent les mêmes références. Ainsi on forme de la même manière les signaux C, D et Q4 (figures 8c, 8d et 8h).The diagram shown in FIG. 7 corresponds to the part associated with the contactor channel of an electronic circuit for controlling an apparatus according to FIGS. 1 and 2, implementing the invention. Elements and signals identical to those of the circuit according to FIG. 5 have the same references. Thus, the signals C, D and Q4 (Figures 8c, 8d and 8h).

Le schéma est complété par un OU EXCLUSIF 98 dont les entrées reçoivent les signaux Q2 et Q3 et fournissant en sortie un signal I, qui est en pratique identique au signal C. Il peut néanmoins être préférable d'utiliser deux circuits en parallèle comme représenté sur la figure 7 pour limiter le nombre de circuits logiques connectés à une même sortie. Un circuit OU 100 recevant en entrée les signaux I et Q1 fournit en sortie un signal J de forme comparable au signal D mais prenant en compte les impulsions C formées après un front descendant du signal A de télécommande et non après un front montant dudit signal.The diagram is completed by an EXCLUSIVE OR 98 whose inputs receive the signals Q2 and Q3 and providing an output signal I, which is in practice identical to the signal C. It may nevertheless be preferable to use two circuits in parallel as shown in Figure 7 to limit the number of logic circuits connected to the same output. An OR circuit 100 receiving the signals I and Q1 as input provides a signal J of a shape comparable to the signal D but taking into account the pulses C formed after a falling edge of the remote control signal A and not after a rising edge of the said signal.

Lorsque le sélecteur S est en mode contacteur (S = 1; figures 1, 4 et 8), le signal S est nul et le signal K de sortie d'un ET 102 recevant en entrée les signaux Q5 et S est également à 0, le signal L de sortie d'un OU EXCLUSIF 104 auquel sont appliqués les signaux K et Q4 est donc identique à Q4 (figure 8h).When the selector S is in contactor mode (S = 1; figures 1, 4 and 8), the signal S is zero and the output signal K of an ET 102 receiving the input signals Q5 and S is also at 0, the signal L from an EXCLUSIVE OU 104 to which the signals K and Q4 is therefore identical to Q4 (figure 8h).

Les signaux A, H, D et L sont appliqués aux entrées d'un circuit ET 106 dont le signal de sortie M est représenté sur la figure 8i. On obtient en sortie M une première impulsion (M1, M2) après chaque front montant (t5,t7) du signal de télécommande A lorsque les contacts mobiles ne sont pas dans la position (B, figure 8f) correspondant à l'ordre de télécommande. Par contre, si les contacts mobiles sont déjà dans la position demandée, ce qui est le cas au temps t9 sur la figure 8, il n'y aura pas d'impulsion sur la sortie M. Après production d'une première impulsion (M2) en M, il y a production d'une seconde impulsion (M′2) si la première impulsion n'a pas conduit à un changement de position des contacts après un temps prédéterminé (1,5 période d'horloge dans le mode de réalisation représenté). On a représenté ce cas en temps t12 sur la figure: il y a alors pendant une période d'horloge des signaux de valeur 1 sur les entrées D, A et L du circuit ET 106 et production d'une seconde impulsion M′2 lorsque H passe à 1, soit 1,5 période après le front descendant de la 1ère impulsion M2.Signals A, H, D and L are applied to the inputs of an AND circuit 106 whose output signal M is shown in Figure 8i. A first pulse (M1, M2) is obtained at output M after each rising edge (t5, t7) of the remote control signal A when the movable contacts are not in the position (B, FIG. 8f) corresponding to the remote control order . On the other hand, if the movable contacts are already in the requested position, which is the case at time t9 in FIG. 8, there will be no pulse on the output M. After production of a first pulse (M2 ) in M, a second pulse (M′2) is produced if the first pulse has not led to a change of position of the contacts after a predetermined time (1.5 clock periods in the shown). This case has been represented in time t12 in the figure: there are then during a clock period signals of value 1 on the inputs D, A and L of the AND circuit 106 and production of a second pulse M′2 when H goes to 1, i.e. 1.5 period after the falling edge of the 1st pulse M2.

Pour un fonctionnement en contacteur, il est bien entendu nécessaire de produire les impulsions appropriées également après un front descendant du signal A de télécommande. Pour cela un circuit ET 108 reçoit les signaux Q4 et S. En mode contacteur (S = 1), sa sortie Q est donc identique à Q4 (figure 8g). Les signaux H, A, J et Q sont appliqués aux entrées d'un circuit ET 110 dont le signal de sortie U est représenté sur la figure 8j. On obtient en sortie U une première impulsion (U1,U2) après chaque front descendant (t6,t8) du signal de télécommande A lorsque les contacts mobiles ne sont pas dans la position demandée. Après production d'une première impulsion (U2) en U, il y a comme précédemment, production d'une seconde impulsion (U′2) si la première n'a pas conduit à un changement de position des contacts après un temps prédéterminé.For contactor operation, it is of course necessary to produce the appropriate pulses also after a falling edge of the remote control signal A. For this, an AND circuit 108 receives the signals Q4 and S. In contactor mode (S = 1), its output Q is therefore identical to Q4 (FIG. 8g). The H signals, AT , J and Q are applied to the inputs of an AND circuit 110 whose output signal U is represented in FIG. 8j. A first pulse (U1, U2) is obtained at output U after each falling edge (t6, t8) of the remote control signal A when the movable contacts are not in the requested position. After production of a first pulse (U2) in U, there is as before, production of a second pulse (U′2) if the first has not led to a change of position of the contacts after a predetermined time.

Les signaux M et U sont appliqués aux entrées d'un circuit OU 112, en sortie duquel on retrouve les signaux V (figure 8k) destinés à la commande de l'interrupteur statique. Comme précédemment on peut isoler les secondes impulsions en utilisant un circuit OU 114 recevant sur ses entrées les signaux C et V et dont la sortie est représentée en W sur la figure 81.The signals M and U are applied to the inputs of an OR circuit 112, at the output of which there are the signals V (FIG. 8k) intended for control of the static switch. As before, the second pulses can be isolated using an OR circuit 114 receiving the signals C and V at its inputs and the output of which is represented at W in FIG. 81.

Lorsque le sélecteur S est en position inactive (S = 0), le signal K de la figure 7 est alors identique à Q5 et le signal L devient identique au signal E de la figure 5, tandis que le signal Q de la figure 7 est nul et force à zéro le signal U de sortie du circuit ET 110. On retrouve alors le même schéma que sur la figure 5, la sortie V correspondant 3à la sortie F. Le signal A de télécommande appliqué à l'entrée CT est alors traîté comme un signal du type télérupteur et le fonctionnement est identique à celui de la voie représentée sur les figures 5 et 6.When the selector S is in the inactive position (S = 0), the signal K in FIG. 7 is then identical to Q5 and the signal L becomes identical to the signal E of figure 5, while the signal Q of figure 7 is null and forces to zero the signal U of output of the circuit ET 110. One finds then the same diagram as in figure 5 , the output V corresponding 3 to the output F. The remote control signal A applied to the input CT is then treated as a signal of the remote control type and the operation is identical to that of the channel shown in FIGS. 5 and 6.

Un circuit électronique de commande destiné à un disjoncteur télécommandé du type représenté sur les figures 1 et 2 comportera donc une première voie telle que représentée sur la figure 5 en parallèle avec une seconde voie telle que représentée sur la figure 7, les entrées H et B étant bien entendu identiques pour les deux voies tandis que sur la 1ère voie est appliqué le signal de télécommande A (TL) appliqué sur l'entrée TL de l'appareil et sur la 2ème voie le signal de télécommande A (CT) appliqué sur l'entrée CT de l'appareil, la valeur du signal S de la 2ème voie étant déterminée par la position du sélecteur S (figure 1) déterminant si le signal d'entrée CT doit correspondre à un fonctionnement en contacteur (S = 1) ou en télérupteur (S = 0).An electronic control circuit intended for a remote-controlled circuit breaker of the type represented in FIGS. 1 and 2 will therefore comprise a first channel as represented in FIG. 5 in parallel with a second channel as represented in FIG. 7, the inputs H and B of course being identical for the two channels while on the 1st channel is applied the remote control signal A (TL) applied to the input TL of the device and on the 2nd channel the remote control signal A (CT) applied to the CT input of the device, the value of the signal S of the 2nd channel being determined by the position of the selector S (figure 1) determining whether the CT input signal must correspond to contactor operation (S = 1) or in a remote control switch (S = 0).

Bien entendu les signaux F et V, et éventuellement G et W, de sortie des deux voies sont, après traitement éventuel, recombinés dans un circuit OU (non représenté) dont la sortie est connectée à l'électrode de commande de l'interrupteur statique 37, si nécessaire par l'intermédiaire d'un circuit d'adaptation.Of course the signals F and V, and possibly G and W, of the output of the two channels are, after possible processing, recombined in an OR circuit (not shown), the output of which is connected to the control electrode of the static switch. 37, if necessary via an adaptation circuit.

Le schéma représenté sur la figure 7 permet l'utilisation de l'entrée A (CT) pour un fonctionnement aussi bien en télérupteur (S = 0) qu'en contacteur (S = 1). Dans le cas où le circuit électronique de commande 39 comporte une entrée A (CT) limitée à un fonctionnement en contacteur, la voie contacteur peut être simplifiée, l'entrée S étant supprimée de même que les bascules 88,90 et les cicrcuits 102,104, et 108. Le signal B est alors appliqué directement, à la place du signal Q, sur la 4ème entrée du circuit ET 110, et par l'intermédiaire d'un inverseur, à la place du signal L sur la 4ème entrée du circuit ET 106. Ainsi pour une voie exclusivement contacteur, la porte ET 106 recevra les signaux H, A, D et B, tandis que la porte ET 110 recevra les signaux H, A, J et B. Il est facile de vérifier que les signaux M et U de sortie des circuits ET 106 et 110 sont identiques à ceux représentés sur la figure 8.The diagram shown in Figure 7 allows the use of input A (CT) for operation as well as a remote control switch (S = 0) than in contactor (S = 1). In the case where the electronic control circuit 39 includes an input A (CT) limited to operation as a contactor, the contactor channel can be simplified, the input S being deleted as well as the flip-flops 88.90 and the microcircuits 102.104, and 108. The signal B is then applied directly, instead of the signal Q, to the 4th input of the AND circuit 110, and by means of an inverter, instead of the signal L to the 4th input of the AND circuit 106. Thus for an exclusively contactor channel, the AND gate 106 will receive the signals H, A, D and B , while the AND gate 110 will receive the signals H, AT , J and B. It is easy to verify that the output M and U signals of the ET circuits 106 and 110 are identical to those shown in Figure 8.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation particuliers représentés sur la figure, mais elle englobe tout appareil télécommandé selon la revendication 1 fonctionnant en télérupteur et/ou en contacteur et dont le circuit électronique de commande permet d'obtenir une seconde impulsion lorsque la première impulsion n'a pas provoqué de changement de position des contacts après un temps prédéterminé.Of course, the invention is not limited to the particular embodiments shown in the figure, but it encompasses any remote-controlled device according to claim 1 operating as a remote control switch and / or as a contactor and whose electronic control circuit makes it possible to obtain a second pulse when the first pulse has not caused a change in position of the contacts after a predetermined time.
