Le module électromagnétique de commutation selon l'invention, repéré M sur les dessins, est destiné à être associé à un appareil interrupteur électromagnétique multipolaire Ap pouvant être pourvu d'une fonction de protection moteur, de type contacteur ou contacteur- disjoncteur. Il peut s'intégrer, en association avec des appareils tels que Ap, dans des schémas classiques tels que : inversion de sens de marche, démarrage étoile- triangle, distribution, changement de vitesse.The electromagnetic switching module according to the invention, marked M in the drawings, is intended to be associated with a multipolar electromagnetic switch device Ap which can be provided with a motor protection function, such as a contactor or a contactor-circuit breaker. It can be integrated, in association with devices such as Ap, in classic schemes such as: reverse direction, star-delta start, distribution, shifting.

L'appareil interrupteur principal Ap loge, dans un boîtier, des lignes de courant polaires disposés entre des bornes de source L1, L2, L3 se connectant aux phases du réseau alternatif et des bornes de charge T1, T2, T3 pouvant se connecter au module de commutation M. Chaque ligne de courant présente un interrupteur ou pôle I1 ou I2 ou I3 commandé par un électroaimant principal E dont la bobine B est alimentée en courant électrique par deux bornes d'alimentation repérées A1 et A2.The main switch device Ap houses, in a housing, polar current lines arranged between source terminals L1, L2, L3 connecting to the phases of the alternating network and charging terminals T1, T2, T3 that can connect to the module. switching circuit M. Each current line has a switch or pole I1 or I2 or I3 controlled by a main electromagnet E whose coil B is supplied with electric current by two power terminals marked A1 and A2.

Le module de commutation M se loge dans un boîtier Bo pourvu à l'arrière d'une embase de fixation P, sensiblement plane, permettant de le fixer sur un rail ou une platine. Il présente des bornes de source (puissance) t1, t2, t3 se raccordant directement sur les bornes aval T1, T2, T3 de l'appareil principal AP et des bornes de sortie ou de charge (puissance) U, V, W d'une part u, v, w d'autre part qui sont connectées au(x) moteur(s).The switching module M is housed in a box Bo provided on the back of a fixing base P, substantially flat, for fixing it on a rail or a plate. It has source (power) terminals t1, t2, t3 connected directly to the downstream terminals T1, T2, T3 of the main apparatus AP and the output or load terminals (power) U, V, W of a part u, v, w on the other hand that are connected to the (x) motor (s).

Le module de commutation M peut se monter directement sous l'appareil Ap ou il peut être déporté.The switching module M can be mounted directly under the apparatus Ap or it can be deported.

Sur les lignes de courant comprises entre les bornes source t1, t2, t3 et les bornes de sortie ou de charge, sont agencés des pôles de commutation C1, C2, C3 du type à rupture simple et bistables. Ces pôles C1, C2, C3 sont actionnés par un électro-aimant bistable El pourvu d'une bobine Bb et leurs contacts sont toujours alternativement fermés sauf pendant les commutations. Le module M ne possède pas de dispositif d'extinction d'arc et ne peut donc pas être actionné en charge. Le nombre de bornes t1, t2, t3 est égal au nombre de bornes T1, T2, T3, le nombre de pôles C1, C2, C3 étant lui-même égal ou inférieur à ce nombre de bornes.On the current lines between the source terminals t1, t2, t3 and the output or load terminals, switching poles C1, C2, C3 of the single-breaking and bistable type are arranged. These poles C1, C2, C3 are actuated by a bistable electromagnet E1 provided with a coil Bb and their contacts are always alternately closed except during switching. The module M does not have an arc extinguishing device and can not be operated under load. The number of terminals t1, t2, t3 is equal to the number of terminals T1, T2, T3, the number of poles C1, C2, C3 itself being equal to or less than this number of terminals.

Les pôles C1, C2, C3 et le câblage interne Sc des lignes de courant associées réalisent une fonction de contrôle de moteur classique : inverseur, étoile-triangle ou distribution, petite vitesse- grande vitesse. Le câblage du circuit du circuit puissance du module M dépend de la fonction de contrôle réalisée par ce module.The poles C1, C2, C3 and the internal wiring Sc of the associated current lines perform a conventional motor control function: inverter, star-delta or distribution, low speed-high speed. The wiring of the circuit of the power circuit of the module M depends on the control function performed by this module.

Dans le mode de réalisation destiné à l'inversion de sens de marche qui est illustré à la figure 1, la borne source t3 est reliée directement à la borne de charge W. Les bornes source t1 et t2 sont reliées (marche directe) aux bornes de charge U et V par les pôles C1, C2 et après commutation de ces mêmes pôles (marche inverse), aux bornes V et U, ce qui réalise le croisement habituel des phases.In the embodiment for reversing direction which is illustrated in Figure 1, the source terminal t3 is connected directly to the charging terminal W. The source terminals t1 and t2 are connected (direct) to the terminals charging U and V by the poles C1, C2 and after switching of these same poles (reverse operation), terminals V and U, which achieves the usual crossing phases.

Dans les modes de réalisation qui sont illustrés à la figure 2, à la figure 3 et à la figure 4 et qui sont destinés respectivement au démarrage étoile-triangle, à la distribution et au changement de vitesse, les bornes de source t1, t2, t3 sont disposées d'un coté du module tandis que les bornes de charge U, V, W (démarrage en triangle ou premier moteur ou grande vitesse) et les bornes de charge u, v, w (démarrage en étoile ou second moteur ou petite vitesse) sont disposées du côté opposé. Les bornes U, V, W d'une part, u, v, w d'autre part sont décalées les unes par rapport aux autres.In the embodiments which are illustrated in FIG. 2, FIG. 3 and FIG. 4 and which are respectively for star-delta starting, distribution and shifting, the source terminals t1, t2, t3 are arranged on one side of the module while the charging terminals U, V, W (delta starting or first motor or high speed) and the charging terminals u, v, w (star start or second motor or small speed) are arranged on the opposite side. The terminals U, V, W on the one hand, u, v, w on the other hand are offset relative to each other.

L'électro-aimant El de type bistable logé dans le module de commutation M et actionnant les contacts mobiles des pôles de commutation C1, C2, C3 est équipé d'un aimant permanent de manière à réduire la consommation d'énergie. Cet électro-aimant El est piloté par un circuit de commande interne Cc illustré à la figure 10. La partie magnétique mobile de l'électro-aimant El qui a un mouvement rectiligne alternatif manoeuvre les pôles de commutation C1, C2, C3 par un coulisseau Ra. De préférence l'axe de déplacement de cet électroaimant est parallèle au plan de fixation Pf et aux bornes.The electromagnet El of bistable type housed in the switching module M and actuating the movable contacts of the switching poles C1, C2, C3 is equipped with a permanent magnet so as to reduce the power consumption. This electromagnet El is controlled by an internal control circuit Cc shown in Figure 10. The movable magnetic part of the electromagnet El which has a reciprocating rectilinear movement maneuvers the switching poles C1, C2, C3 by a slider Ra. Preferably, the axis of displacement of this electromagnet is parallel to the plane of attachment Pf and to the terminals.

Le module de commutation M est agencé de manière que les pôles de commutation C1, C2, C3 et les circuits de puissance associés et que l'ensemble de commande des pôles formé par l'électro-aimant El et le circuit de commande Cc soient décalés ou espacés selon une direction perpendiculaire à la face arrière Pf de fixation du module et que la largeur L du module soit sensiblement égale à la largeur de l'appareil principal associé Ap. La largeur L est donc réduite si on la compare à des appareils usuels réalisant des fonctions similaires. Les pôles de commutation C1, C2, C3 et les conducteurs Sc du schéma de câblage (inverseur, etc ) sont logés vers l'arrière, l'électroaimant El et le circuit de commande Cc associé étant logés vers l'avant.The switching module M is arranged so that the switching poles C1, C2, C3 and the associated power circuits and the pole control assembly formed by the electromagnet El and the control circuit Cc are offset. or spaced in a direction perpendicular to the rear face Pf for fixing the module and that the width L of the module is substantially equal to the width of the associated main apparatus Ap. The width L is therefore reduced when compared to conventional apparatus performing similar functions. The switching poles C1, C2, C3 and the conductors Sc of the wiring diagram (inverter, etc.) are housed towards the rear, the electromagnet El and the associated control circuit Cc being housed towards the front.

Chaque pôle de commutation C1 ou C2 ou C3 illustré schématiquement à la figure 6 est de type inverseur (contacts toujours fermés) et est constitué par un porte contact mobile Pc portant deux conducteurs parallèles Cm1, Cm2 en forme de boucles et portant respectivement les contacts mobiles P1 et P2. Ces conducteurs sont réunis à une borne t1, t2, t3. Le porte- contact Pc oscille, autour d'un tourillon Ax et d'un axe A-A', entre deux conducteurs Cf1, Cf2 portant les contacts fixes P3 et P4. Ces conducteurs sont eux-mêmes en forme de boucle et réunis à une ou deux bornes U, V, W. Dans le mode de réalisation représenté les axes sont perpendiculaires au plan de fixation arrière Pf.Each switching pole C1 or C2 or C3 illustrated schematically in FIG. 6 is of the inverter type (contacts always closed) and is constituted by a mobile contact carrier Pc carrying two parallel conductors Cm1, Cm2 in the form of loops and carrying respectively the moving contacts. P1 and P2. These conductors are joined to a terminal t1, t2, t3. The contact carrier Pc oscillates around a pin Ax and an axis A-A 'between two conductors Cf1, Cf2 carrying the fixed contacts P3 and P4. These conductors are themselves in the form of a loop and joined to one or two terminals U, V, W. In the embodiment shown, the axes are perpendicular to the rear fixing plane Pf.

Le porte- contact mobile Pc oscille, autour de l'axe A-A', d'une première position de travail, contacts fermés, à une seconde position de travail, contacts fermés également. Le courant qui circule dans un conducteur mobile Cm1 ou Cm2 et dans le conducteur fixe correspondant Cf1 ou Cf2, selon des directions parallèles, induit un effort d'attraction magnétique. Cet effet de boucle permet d'obtenir une pression de contact proportionnelle au courant qui passe dans le pôle. Les pôles ne sont jamais actionnés en charge ce qui permet de réduire la pression nominale de contact, l'encombrement de l'électroaimant se trouvant diminué.The movable contact carrier Pc oscillates around the axis A-A ', from a first working position, closed contacts, to a second working position, closed contacts also. The current flowing in a moving conductor Cm1 or Cm2 and in the corresponding fixed conductor Cf1 or Cf2, in parallel directions, induces a magnetic attraction force. This loop effect makes it possible to obtain a contact pressure proportional to the current flowing in the pole. The poles are never operated under load, which makes it possible to reduce the nominal contact pressure, the size of the electromagnet being reduced.

Les parties mobiles de l'électro-aimant actionnent un coulisseau Ra mobile en translation parallèlement au plan arrière de fixation Pf et agissant sur chaque ressort de pôle Rp par l'intermédiaire d'une pièce Pi.The moving parts of the electromagnet actuate a slider Ra movable in translation parallel to the rear fixing plane Pf and acting on each pole spring Rp via a piece Pi.

Les conducteurs fixes Cf1, Cf2 réalisent avec des prolongements ou des conducteurs complémentaires aboutissant aux bornes de charge (puissance) U, V, W etc, un des schémas de contrôle Sc du moteur ou des moteurs. Ces prolongements ou conducteurs complémentaires sont logés dans le boîtier Bo, du coté des bornes de charge.The fixed conductors Cf1, Cf2 realize with extensions or complementary conductors terminating at the charging terminals (power) U, V, W etc, one of the control schemes Sc of the motor or engines. These extensions or complementary conductors are housed in the box Bo, on the side of the charging terminals.

Les conducteurs mobiles Cm1, Cm2 du porte-contact PC sont distants, l'un par rapport à l'autre, de manière qu'un noyau magnétique No se loge entre eux. Ce noyau magnétique No coopère avec des contreplaques Cp1, Cp2 fixées à l'intérieur de la chambre de commutation logeant le pôle. Les pièces de contacts mobiles Cm1, Cm2 sont réunies par une liaison électrique souple Tr et un conducteur tel que Co3 à une borne source telle que t3.The mobile conductors Cm1, Cm2 of the contact carrier PC are distant relative to each other, so that a magnetic core No is housed between them. This magnetic core No cooperates with counterplates Cp1, Cp2 fixed inside the switching chamber housing the pole. The moving contact parts Cm1, Cm2 are connected by a flexible electrical connection Tr and a conductor such as Co3 to a source terminal such that t3.

Les bornes d'entrée et de sortie servant au contrôle sont disposées vers l'avant. Les bornes d'entrée A2, A1, A1', B1, B1' sont destinées à recevoir les ordres de commande du moteur et les bornes de sortie SA1, S21, S22 coopèrent avec l'appareil principal associé Ap.The input and output terminals for control are arranged forward. The input terminals A2, A1, A1 ', B1, B1' are intended to receive the motor control commands and the output terminals SA1, S21, S22 cooperate with the associated main apparatus Ap.

L'appareil principal Ap comporte un contact de verrouillage Ve manoeuvré par la partie mobile de l'électro-aimant E et connecté à deux bornes 21 et 22 pouvant se connecter aux bornes SA1 et SA2 du module M.The main apparatus Ap comprises a locking contact Ve operated by the moving part of the electromagnet E and connected to two terminals 21 and 22 which can be connected to the terminals SA1 and SA2 of the module M.

La bobine Bb de l'électro-aimant El est alimentée de manière à être polarisée dans l'un ou l'autre sens. Cette commande peut être réalisée par deux contacts inverseurs auxiliaires 1a et 1b actionnés par la partie mobile de l'électroaimant bistable El et associés à des diodes 7a, 7b. Le module de commutation M peut comporter d'autres contacts auxiliaires tels que 3 et 6 également actionnés par la partie mobile de l'électro-aimant El.The coil Bb of the electromagnet E1 is fed so as to be biased in either direction. This control can be performed by two auxiliary inverter contacts 1a and 1b actuated by the movable part of the bistable electromagnet E1 and associated with diodes 7a, 7b. The switching module M may comprise other auxiliary contacts such as 3 and 6 also actuated by the moving part of the electromagnet El.

Pour réaliser l'application, on branche sur les bornes A1, A'1, B1, B'1 du module de commutation M d'une part des contacts Bp1 contrôlant le fonctionnement dans le «sens un» et d'autre part des contacts Bp2 contrôlant le fonctionnement dans le « sens deux ». On appelle fonctionnement « sens un », l'un des deux modes de fonctionnement du module c'est à dire la marche directe pour l'inverseur ou en étoile pour l'étoile-triangle. On appelle fonctionnement « sens deux » le second mode c'est à dire la marche inverse ou en triangle.To carry out the application, the terminals A1, A'1, B1, B'1 of the switching module M are connected on the one hand with the contacts Bp1 controlling the operation in the "one direction" and on the other hand with the contacts Bp2 controlling the operation in the "two direction". One-way operation is defined as one of the two modes of operation of the module, ie direct operation for the inverter or star for the star-delta. The second mode is called "direction two" operation, ie the reverse or triangle operation.

Le fonctionnement du module de commutation va maintenant être expliqué.The operation of the switching module will now be explained.

Dans la position de la figure 10, l'électro-aimant El de l'appareil principal Ap est alimenté via l'interrupteur de marche-arrêt MA, les contacts Bp1, Bp2 et 6. Les pôles de puissance 11, 12 et 13 de l'appareil principal Ap sont dans la position de fonctionnement « sens un ». Les interrupteurs de commutation tels que C1, C2 du module de commutation M sont dans la position correspondant à ce mode de fonctionnement «sens un » (ces pôles sont toujours en position fermée).In the position of FIG. 10, the electromagnet E1 of the main apparatus Ap is powered via the ON / OFF switch MA, the contacts Bp1, Bp2 and 6. The poles of power 11, 12 and 13 of the main apparatus Ap are in the operating position "direction one". Switching switches such as C1, C2 of the switching module M are in the position corresponding to this operating mode "direction one" (these poles are always in the closed position).

Pour passer en mode de fonctionnement «sens deux», l'opérateur ouvre un contact Bp2 et ferme le contact associé Bp2. L'ouverture du contact coupe l'alimentation de la bobine B de l'appareil principal Ap. Les interrupteurs de puissance 11 à 13 de l'appareil principal Ap s'ouvrent.To enter the "two way" operating mode, the operator opens a contact Bp2 and closes the associated contact Bp2. The opening of the contact interrupts the supply of the coil B of the main apparatus Ap. The power switches 11 to 13 of the main apparatus Ap open.

La fermeture du contact Bp2 entraîne l'alimentation de la bobine Bb du module M ce qui entraîne la commutation des contacts de commutation tels que C1, C2. Les contacts auxiliaires du module M commutent et le courant est envoyé sur l'électroaimant E de l'appareil principal Ap de manière à manoeuvrer les interrupteurs de puissance 11-13.The closing of the contact Bp2 causes the supply of the coil Bb of the module M which causes the commutation of the switching contacts such as C1, C2. The auxiliary contacts of the module M switch and the current is sent on the electromagnet E of the main apparatus Ap so as to operate the power switches 11-13.

L'électro-aimant El du module de commutation M ne peut commuter que lorsque les contacts de puissance 11 à 13 sont ouverts. Cette fonction de sécurité est assurée par le contact Ve de verrouillage. D'autre part, les contacts de puissance 11 à 13 se ferment lorsque les contacts du module de commutation M sont dans la bonne position.The electromagnet E1 of the switching module M can only switch when the power contacts 11 to 13 are open. This safety function is provided by the locking contact V. On the other hand, the power contacts 11 to 13 close when the contacts of the switching module M are in the correct position.

Afin de ne pas couper la tension d'alimentation durant la course de l'électro-aimant El, les contacts auxiliaires doivent changer de position après que l'électro-aimant El ait effectué sa course ou une partie importante de sa course. Un dispositif de retardement de changement d'état peut être associé à ces trois contacts.In order not to cut the supply voltage during the travel of the electromagnet El, the auxiliary contacts must change position after the electromagnet El has run or a significant part of its travel. A state change delay device may be associated with these three contacts.

Il est bien entendu que l'on peut sans sortir du cadre des revendications imaginer des variantes et des perfectionnements de détail et de même envisager l'emploi de moyens équivalents.It is understood that one can without departing from the scope of claims imagine variants and refinements of detail and even consider the use of equivalent means.

En variante on pourrait éviter d'employer dans le schéma de commande Cc des semi-conducteurs (diodes ou petits composants de protection).Alternatively one could avoid using in the control scheme Cc semiconductors (diodes or small protective components).
