Abstract

A contactor apparatus comprising means for automatically opening power circuits should faults occur and a local control member. This apparatus comprises a plurality of power lines (8) each comprising a power contact (2) adapted to be opened during a short circuit by a striker (28), a coil (13) and a bimetallic strip (14), responding to smaller overloads. The elements responsive to overcurrents act on a cascade of sudden tripping devices (19) (17) (31) which govern the positions of the local control member (18) and act on a control switch (4) placed in series with the electromagnet (1). Such an apparatus is advantageously used in installations where protection of the lines, remote control and local control of the consumer apparatus are desired.

Description

L'invention se rapporte à un appareil contacteur comportant un électro-aimant de commande des contacts de puissance et présentant des moyens d'ouverture automatique de ces contacts de puissance qui répondent chacun, d'une part, à l'apparition de courants de court-circuit dans l'un des circuits de puissance grâce à une première bobine et à un percuteur, et, d'autre part, à l'apparition de courants de surcharges soit instantanés, soit de durée plus importante grâce à une deuxième bobine associée à une palette et, respectivement, à un bilame, chaque contact de puissance étant apte à coopérer, après percussion, avec un organe de verrouillage qui le maintient en position ouverte, cet appareil présentant un organe de commande locale apte à réarmer les moyens d'ouverture automatique et à refermer un interrupteur de contrôle placé en série avec le bobinage de l'électro-aimant.The invention relates to a contactor device comprising an electromagnet for controlling the power contacts and having means for automatic opening of these power contacts which each respond, on the one hand, to the appearance of short currents -circuit in one of the power circuits thanks to a first coil and a striker, and, on the other hand, to the appearance of overload currents either instantaneous or of greater duration thanks to a second coil associated with a paddle and, respectively, to a bimetallic strip, each power contact being able to cooperate, after percussion, with a locking member which keeps it in the open position, this device having a local control member capable of resetting the opening means automatic and to close a control switch placed in series with the electromagnet winding.

De tels contacteurs, qui sont destinés à assurer simultanément l'alimentation d'appareils consommateurs et leur protection rapide ainsi que celle des lignes qui les alimentent, évitent de faire appel au montage série de deux appareils ayant chacun un système d'interrupteurs dont l'un est destiné à effectuer le service marche et arrêt et dont l'autre est destiné à assurer la protection; on sait, en effet, qu'une telle association entre ces deux systèmes d'interrupteurs nécessite une coordination qu'il est difficile d'obtenir en raison des propriétés radicalement différentes qui sont demandées tant à leurs pouvoirs de fermeture qu'à leurs vitesses d'ouverture. Cette coordination est d'autant plus délicate à réaliser que chacun de ces types d'interrupteurs peut être offert au public par des fournisseurs distincts et que leurs propriétés ne sont pas toujours connues des utilisateurs.Such contactors, which are intended to simultaneously supply the power to consumer devices and their rapid protection, as well as that of the lines which supply them, avoid the need for series mounting of two devices each having a system of switches, the one is intended to perform the on and off service and the other of which is intended to provide protection; we know, in fact, that such an association between these two switch systems requires coordination which is difficult to obtain because of the radically different properties which are required both for their closing powers and for their speeds d 'opening. This coordination is all the more difficult to achieve since each of these types of switches can be offered to the public by separate suppliers and their properties are not always known to users.

Dans un appareil connu, répondant à la constitution générale mentionnée ci-dessus, les dispositifs percuteurs et les dispositifs magnétiques qui doivent répondre à l'apparition de surintensités de valeurs et de durée distinctes font appel à un seul et même bobinage, de sorte que les réglages des seuils mentionnés ci-dessus ne sont pas totalement indépendants; par ailleurs, cet appareil connu ne s'intéresse pas à la totalité des fonctions qu'il serait souhaitable de réserver à la commande locale.In a known device, responding to the general constitution mentioned above, the striker devices and the magnetic devices which must respond to the occurrence of overcurrents of distinct values and duration use a single winding, so that the threshold settings mentioned above are not completely independent; moreover, this known device is not interested in all of the functions which it would be desirable to reserve for local control.

Lorsque l'on prévoit que le réarmement de l'appareil se fait à l'aide d'une commande, que celle-ci soit locale ou à distance, il est nécessaire de mettre en oeuvre des mesures propres à assurer un découplage total entre des organes qui assurent le fonctionnement automatique de sécurité et ceux qui, soit de façon simultanée, soit ultérieurement à une coupure automatique, doivent être actionnés pour ouvrir les circuits et respectivement mettre ou remettre l'appareil en service; le but de ce découplage est, d'une part, d'éviter qu'une action locale de fermeture exécutée sur l'organe de commande locale, en présence d'un défaut, soit suivie d'effet et, d'autre part, d'assurer qu'une coupure automatique provoquant la mise en mouvement de certaines pièces indispensables ne soit pas accompagnée par la mise en mouvement d'autres éléments mécaniques non nécessaires à l'accomplissement de la fonction de sécurité.When provision is made for the device to be rearmed by means of a command, whether this is local or remote, it is necessary to implement measures capable of ensuring total decoupling between organs which ensure automatic safety operation and those which, either simultaneously or after an automatic cut-off, must be actuated to open the circuits and respectively put or put the device back into service; the purpose of this decoupling is, on the one hand, to prevent a local closing action executed on the local control member, in the presence of a fault, from being followed by effect, and, on the other hand, ensure that an automatic cut-off causing certain essential parts to move is not accompanied by the movement of other mechanical elements not necessary for the performance of the safety function.

Selon l'invention, le résultat recherché est atteint grâce au fait que l'organe de commande locale est soumis à une force élastique interne et coopère:

  • - d'une part avec un premier mécanisme à déclenchement brusque dont il fait partie et qui est apte à le retenir dans une première position stable F, donnée par voie extérieure, et qui effectue la fermeture de l'interrupteur de contrôle pour cette seule position F, et
  • - d'autre part avec un deuxième mécanisme à déclenchement brusque, soit de façon à conserver une deuxième position stable 0 qui est donnée à l'organe de commande par voie extérieure, soit de façon à prendre automatiquement une troisième position stable D comprise entre les précédentes, lorsque le premier mécanisme est déclenché par le deuxième mécanisme, ce deuxième mécanisme étant déclenché par des poussées exercées sans liaison,
  • - soit directement par un moyen réagissant lorsque le contact mobile du contact de puissance est verrouillé par suite de l'excitation de ladite première bobine associée au percuteur et placée en série avec le contact de puissance,
  • - soit indirectement par un troisième mécanisme à déclenchement brusque qui est libéré par les mouvements fournis par une palette de ladite deuxième bobine ou respectivement par un bilame, placés en série avec la première bobine et avec le contact de puissance,

ces deuxième ettroisième mécanismes recevant un mouvement de réarmement fourni par l'organe de commande locale lorsque ce dernier est amené par voie extérieure dans une quatrième position R, qui est opposée à la première position.According to the invention, the desired result is achieved thanks to the fact that the local control member is subjected to an internal elastic force and cooperates:
  • on the one hand with a first abrupt trigger mechanism of which it is a part and which is capable of retaining it in a first stable position F, given externally, and which performs the closing of the control switch for this single position F, and
  • - on the other hand with a second abrupt trigger mechanism, either so as to maintain a second stable position 0 which is given to the control member externally, or so as to automatically assume a third stable position D between the previous, when the first mechanism is triggered by the second mechanism, this second mechanism being triggered by pushes exerted without connection,
  • either directly by a means reacting when the movable contact of the power contact is locked as a result of the excitation of said first coil associated with the striker and placed in series with the power contact,
  • - either indirectly by a third mechanism with abrupt release which is released by the movements provided by a pallet of said second coil or respectively by a bimetallic strip, placed in series with the first coil and with the power contact,

these second and third mechanisms receiving a reset movement provided by the local control member when the latter is brought externally into a fourth position R, which is opposite to the first position.

L'invention ainsi que d'autres buts et d'autres mesures visant des résultats complémentaires, tels que l'adaptation au courant d'emploi des organes détecteurs de courant utilisant des bobines et/ou des bilames qui agissent sur le troisième mécanisme, seront mieux compris à la lecture de la description ci-après.The invention as well as other aims and other measures aiming at complementary results, such as the adaptation to the current of use of the current detecting members using coils and / or bimetallic strips which act on the third mechanism, will be better understood on reading the description below.

Dans le schéma de principe représentant un appareil conforme à l'invention et visible à la fig. a, un électro-aimant 1 permet d'actionner un ou une multiplicité n de contacts de puissance tels que 2; cet actionnement est unidirectionnel grâce au fait qu'un ressort de rappel 36 d'une armature 29 de cet électro-aimant repousse sans liaison un contact mobile 12 de chaque contact de puissance contre l'action d'un ressort de pression de contact 15 qui s'appuie sur le boîtier 20 de l'appareil et qui tend à fermer le contact; cette action unidirectionnelle est signalée par f lorsque l'armature est attirée et que le contact se ferme, et dans le cas contraire.In the block diagram representing an apparatus according to the invention and visible in FIG. a, an electromagnet 1 activates a or a multiplicity n of power contacts such as 2; this actuation is unidirectional thanks to the fact that a return spring 36 of a frame 29 of this electromagnet pushes without moving a movable contact 12 of each power contact against the action of a contact pressure spring 15 which is based on the housing 20 of the device and which tends to close the contact; this unidirectional action is indicated by f when the armature is attracted and the contact closes, and if not.

L'électro-aimant comporte une bobine 3 qui est placée en série avec un interrupteur de contrôle 4 dans un circuit de contrôle 7 ayant des bornes 6 et 5 aptes à recevoir une tension extérieure lorsque les contacts de puissance doivent être fermés.The electromagnet comprises a coil 3 which is placed in series with a control switch 4 in a control circuit 7 having terminals 6 and 5 able to receive an external voltage when the power contacts must be closed.

L'électro-aimant et les contacts de puissance sont analogues à ceux d'un contacteur en vue d'effectuer les fonctions correspondantes.The electromagnet and the power contacts are analogous to those of a contactor in order to perform the corresponding functions.

Un circuit de puissance 8, passant par le contact de puissance 2, est compris entre les bornes de raccordement 10 et 9 destinées à être reliées à un réseau et respectivement un appareil consommateur non représentés.A power circuit 8, passing through the power contact 2, is included between the connection terminals 10 and 9 intended to be connected to a network and respectively a consumer device not shown.

Le circuit 8 comprend, en série avec le contact 2, un bobinage 11, auquel est associé un percuteur 28 qui est déplacé très rapidement lorsque le circuit est parcouru par des courants tels que ceux qui apparaissent au cours d'un court-circuit franc en aval de l'appareil.The circuit 8 comprises, in series with the contact 2, a winding 11, with which is associated a striker 28 which is moved very quickly when the circuit is traversed by currents such as those which appear during a short-circuit frank in downstream of the device.

Ce percuteur peut repousser dans ce cas le contact mobile 12, indépendamment de l'armature de l'électro-aimant, et jusqu'à une position d'ouverture supérieure à celle qui lui est donnée par les ressorts de l'armature. Cette action est repérée par la référence a.This striker can push the movable contact 12 in this case, independently of the armature of the electromagnet, and to an open position greater than that given to it by the springs of the armature. This action is identified by the reference a.

Dans cette position, le contact mobile 12 coopère avec un verrou élastique 16 qui est apte à le retenir pour empêcher une refermeture du circuit après l'apparition d'un tel défaut.In this position, the movable contact 12 cooperates with an elastic lock 16 which is capable of retaining it to prevent reclosing of the circuit after the appearance of such a defect.

Le circuit 8 comprend encore en série un second bobinage 13 qui coopère de façon connue avec une palette 34 ou un noyau plongeur, non représenté, de façon à leur communiquer un mouvement rapide repéré par b, lorsque apparaissent dans ce circuit des courants instantanés élevés tels que ceux que l'on rencontre au cours de surcharges de courtes durées ou à l'occasion de courts-circuits impédants.The circuit 8 also comprises in series a second winding 13 which cooperates in a known manner with a pallet 34 or a plunger core, not shown, so as to communicate to them a rapid movement indicated by b, when there appear in this circuit high instantaneous currents such than those encountered during short-term overloads or during impedant short-circuits.

Un bilame 14 est également placé en série dans le circuit 8 et fournit une déflection signalée par c lorsque apparaissent dans ce circuit des courants, moins importants que les précédents, mais de durée plus importante, tels que ceux qui se développent au cours de surcharges faibles mais prolongées.A bimetallic strip 14 is also placed in series in circuit 8 and provides a deflection indicated by c when currents appear in this circuit, less important than the preceding ones, but of greater duration, such as those which develop during weak overloads. but prolonged.

Un premier mécanisme à déclenchement brusque 31 réarmable est associé mécaniquement, par un moyen de transmission représenté schématiquement par 32, à un organe de commande locale 18 et reçoit de ce dernier une force élastique unidirectionnelle délivrée par un ressort 35.A first resettable trigger mechanism 31 is mechanically associated, by a transmission means represented diagrammatically by 32, with a local control member 18 and receives from the latter a unidirectional elastic force delivered by a spring 35.

Ce mécanisme 31 dont fait partie le moyen de transmission 32 est apte à retenir, par une action m, l'organe de commande locale dans une première position F stable qui lui est communiquée de l'extérieur par exemple par une action manuelle sur cet organe; l'organe 18 est libéré par une action m lorsque ce premier mécanisme 31 est déclenché par une voie interne p de l'appareil décrite ultérieurement.This mechanism 31, of which the transmission means 32 is a part, is capable of retaining, by an action m, the local control member in a first stable position F which is communicated to it from the outside, for example by manual action on this member ; the member 18 is released by an action m when this first mechanism 31 is triggered by an internal path p of the device described later.

Ce premier mécanisme 31 gouverne par ailleurs les états de fermeture et d'ouverture de l'interrupteur de contrôle 4 par des actions e et respectivement é, la fermeture étant uniquement opérée lorsque ce mécanisme retient la position F de l'organe de commande.This first mechanism 31 also governs the closing and opening states of the control switch 4 by actions e and respectively é, the closure being only operated when this mechanism retains the position F of the control member.

Lorsque l'interrupteur 4 est fermé, l'électro-aimant 1 peut être excité par un signal d'ordre appliqué aux bornes 5 et 6 en vue d'effectuer la fermeture des contacts de puissance 2.When the switch 4 is closed, the electromagnet 1 can be excited by an order signal applied to the terminals 5 and 6 in order to close the power contacts 2.

L'organe de commande 18 coopère également, par exemple, par la même transmission 32, avec un deuxième mécanisme à déclenchement brusque 17 par des actions de contact représentées par j. Ce deuxième mécanisme à déclenchement brusque 17 est apte à délivrer l'action p lorsqu'il est déclenché par l'un de deux mouvements g ou d fournis par des voies internes au cours d'un processus d'ouverture automatique interne de l'appareil.The control member 18 also cooperates, for example, by the same transmission 32, with a second abrupt trigger mechanism 17 by contact actions represented by j. This second abrupt trigger mechanism 17 is capable of delivering the action p when it is triggered by one of two movements g or d supplied by internal channels during an internal automatic opening process of the device. .

L'action représentée d'une façon générale par g résulte de l'excitation de la bobine 11 par un courant très important et pourrait à ce titre être délivrée par le percuteur 28 lui-même ou par une palette (non représentée) qui serait associée à la bobine 11.The action generally represented by g results from the excitation of the coil 11 by a very large current and could as such be delivered by the striker 28 itself or by a pallet (not shown) which would be associated to coil 11.

Dans un mode de réalisation préféré de l'invention, illustré ci-dessous, l'action g est délivrée par le verrou 16 dès que celui-ci a pris une position correspondant à l'exécution effective du verrouillage du contact mobile 12, de sorte que l'apparition de l'action g correspond effectivement à l'apparition, dans la bobine 11, d'un courant d'intensité suffisante pour que le percuteur amène le contact mobile dans une position extrême d'ouverture verrouillée.In a preferred embodiment of the invention, illustrated below, the action g is delivered by the lock 16 as soon as the latter has taken a position corresponding to the effective execution of the locking of the movable contact 12, so that the appearance of the action g actually corresponds to the appearance, in the coil 11, of a current of sufficient intensity for the striker to bring the movable contact into an extreme locked opening position.

L'action représentée par d est délivrée par un troisième mécanisme à déclenchement brusque 19, lorsque celui-ci est libéré par l'apparition de l'une des deux actions b ou c définies ci-dessus. Ces deux actions g et d sont unidirectionnelles, c'est-à-dire qu'elles transmettent des mouvements sans liaison permanente entre deux pièces, de préférence par une poussée. Les deux mécanismes à déclenchement brusque 17,19 sont réarmés l'un par l'autre à l'aide de l'organe de commande locale 18 par des actions représentées par et respectivement K lorsqu'une position particulière de réarmement R est communiquée à celui-ci; ce même mouvement de réarmement exerce également une action de déverrouillage h transmise par le deuxième mécanisme 17 pour libérer le contact mobile 12 du verrou élastique 16.The action represented by d is delivered by a third abrupt trigger mechanism 19, when this is released by the appearance of one of the two actions b or c defined above. These two actions g and d are unidirectional, that is to say that they transmit movements without permanent connection between two parts, preferably by a push. The two abrupt trigger mechanisms 17,19 are reset by each other using the local control member 18 by actions represented by and K respectively when a particular reset position R is communicated to that -this; this same rearming movement also exerts an unlocking action h transmitted by the second mechanism 17 to release the movable contact 12 from the elastic lock 16.

Pendant que s'exerce l'opération de réarmement qui est transmise du deuxième mécanisme à déclenchement brusque 17 vers le troisième mécanisme à déclenchement brusque 19, l'interrupteur 4 reste ouvert.While the reset operation is being carried out, which is transmitted from the second snap mechanism 17 to the third snap mechanism 19, the switch 4 remains open.

Par ailleurs, le réarmement du deuxième mécanisme 17 ne peut être opéré que si le troisième mécanisme 19 est en état d'être réarmé, c'est-à-dire en l'absence des actions b et c; comme, pour la position de réarmement, l'interrupteur 4 est ouvert, le contact de puissance 2 est forcément ouvert de sorte que seule une action c développée par un bilame 14 encore chaud peut en fait empêcher le réarmement immédiat du second mécanisme 19.Furthermore, the rearming of the second mechanism 17 can only be carried out if the third mechanism 19 is in a state of being reset, that is to say in the absence of actions b and c; as, for the reset position, the switch 4 is open, the power contact 2 is necessarily open so that only an action c developed by a bimetallic strip 14 still hot can in fact prevent the immediate reset of the second mechanism 19.

L'organe de commande locale 18 effectue des déplacements entre deux positions extrêmes opposées, F correspondant à la fermeture de l'interrupteur 4 et R correspondant à l'opération de réarmement. Une position stable 0 d'ouverture externe locale, par exemple manuelle, de l'interrupteur 4 est placée entre ces deux positions extrêmes. Cette ouverture de l'interrupteur 4 est réalisée en raison du fait que lorsque l'organe de commande locale quitte la position F, une action m est établie entre la transmission 32 et le premier mécanisme 31.The local control member 18 moves between two opposite extreme positions, F corresponding to the closing of the switch 4 and R corresponding to the reset operation. A stable position 0 of local external opening, for example manual, of the switch 4 is placed between these two extreme positions. This opening of the switch 4 is carried out due to the fact that when the local control member leaves the position F, an action m is established between the transmission 32 and the first mechanism 31.

Lorsqu'un défaut, de quelque nature que ce soit, apparaît sur le circuit de puissance 8, le deuxième mécanisme à déclenchement brusque 17 provoque immédiatement l'ouverture de l'interrupteur 4 par le premier mécanisme 31, mais prend alors un état intermédiaire déclenché qui confère à l'organe de commande locale 18 par l'action j une position intermédiaire stable D comprise entre les positions F et O; cette position ne peut être donnée à l'organe de commande locale par une action manuelle sur celui-ci. Les positions F, D et 0 sont donc toutes trois des positions stables de l'organe de commande de sorte que cet organe 18 restitue non seulement une image exacte des états de l'appareil, mais informe également l'utilisateur sur la nature des événements qui les ont produits: action externe locale ou ouverture automatique interne.When a fault of any kind appears on the power circuit 8, the second abrupt-release mechanism 17 immediately causes the switch 4 to open by the first mechanism 31, but then takes an intermediate state triggered which gives the local control member 18 by action j a stable intermediate position D between the positions F and O; this position cannot be given to the local control member by manual action thereon. The positions F, D and 0 are therefore all three stable positions of the control member so that this member 18 not only reproduces an exact image of the states of the apparatus, but also informs the user of the nature of the events. who produced them: local external action or internal automatic opening.

La position R est par contre instable et ne peut être obtenue que par le maintien d'un effort permanent, manuel ou autre, sur l'organe de commande locale et, éventuellement, contre une seconde action élastique d'un ressort représenté par 30.On the other hand, the position R is unstable and can only be obtained by maintaining a permanent force, manual or otherwise, on the local control member and, possibly, against a second elastic action of a spring represented by 30.

Si l'on suppose que l'appareil a été placé originellement en position de fermeture F et qu'apparaisse ensuite un courant de court-circuit, l'organe de commande locale prend une position automatique déclenchée D; le réarmement de l'appareil nécessite que cet organe de commande soit déplacé, par voie extérieure, d'abord en position 0 puis en position R (et soit ramené ensuite vers la position F). Comme, pour un défaut de cette nature, le bilame n'a pu se déformer suffisamment, et que la bobine 13 n'a pas eu le temps suffisant pour agir, le troisième mécanisme 19 n'est pas libéré, le second mécanisme a d'abord pu se réarmer, (action j), et a pu ensuite libérer le contact mobile 12 de son verrou 16 (action h) ; l'interrupteur 4 ne pouvant être fermé par le premier mécanisme 31, grâce à l'action e, que lorsque l'organe de commande locale atteint la position F, cette fermeture va provoquer (si une tension est toujours présente aux bornes 5, 6) une excitation de l'électro-aimant et donc la fermeture du contact de puissance 2. Si le court-circuit est toujours présent, la bobine 11 va exciter le percuteur 28 qui ouvrira à nouveau le contact mobile 12 et provoquera la libération du premier mécanisme à déclenchement brusque, ce qui entraînera la réouverture immédiate de l'interrupteur 4 et donc celle des contacts de puissance 2. Toutefois, en cas d'action préalable du mécanisme 17, le mécanisme 31 maintient l'action e d'ouverture du contact 4 de sorte que le maintien volontaire de l'organe 18 en position F ne produit pas, en cas de défaut permanent, la refermeture forcée du contact 4.If it is assumed that the apparatus was originally placed in the closed position F and that a short-circuit current then appears, the local control member assumes an automatic triggered position D; resetting the device requires that this control member be moved, externally, first to position 0 then to position R (and then be brought back to position F). As, for a defect of this nature, the bimetallic strip could not deform sufficiently, and the coil 13 did not have sufficient time to act, the third mechanism 19 is not released, the second mechanism has d 'was first able to reset, (action j), and was then able to release the movable contact 12 from its lock 16 (action h); the switch 4 being able to be closed by the first mechanism 31, thanks to the action e, only when the local control member reaches the position F, this closing will cause (if a voltage is always present at the terminals 5, 6 ) an excitation of the electromagnet and therefore the closing of the power contact 2. If the short circuit is still present, the coil 11 will excite the striker 28 which will again open the movable contact 12 and cause the release of the first mechanism with abrupt release, which will cause the immediate reopening of the switch 4 and therefore that of the power contacts 2. However, in the event of prior action of the mechanism 17, the mechanism 31 maintains the action e of opening the contact 4 so that the voluntary maintenance of the member 18 in position F does not produce, in the event of a permanent fault, the forced reclosing of the contact 4.

Si, au contraire, l'appareil a été placé originellement en position F et qu'apparaisse ensuite une surcharge lente qui provoque la déflection thermique des bilames 14, l'organe de commande prend une position automatique déclenchée D mais l'action c conserve son état pendant un certain temps nécessaire au refroidissement de ces bilames.If, on the contrary, the apparatus was originally placed in position F and then a slow overload appears which causes thermal deflection of the bimetallic strips 14, the control member assumes an automatic triggered position D but the action c retains its condition for a certain time necessary for the cooling of these bimetallic strips.

Tant que les bilames ne sont pas refroidis ni le troisième mécanisme à déclenchement brusque 19, ni, par suite, le deuxième mécanisme 17 ne peuvent être réarmés, tors d'une mise en position R de l'organe de commande 18. Il en résulte que l'action p étant toujours présente, le premier mécanisme à déclenchement brusque 31 ne pourra pas être réarmé par une action m qui lui sera communiquée par l'organe de commande 18 lorsque celui-ci atteindra la position D.As long as the bimetallic strips are not cooled nor the third mechanism with abrupt trigger 19, nor, consequently, the second mechanism 17 can not be reset, tors of a setting in position R of the control member 18. This results that the action p being always present, the first abrupt trigger mechanism 31 cannot be reset by an action m which will be communicated to it by the control member 18 when the latter reaches the position D.

Dans le schéma de principe représenté à la fig. 1 a, les actions ou déplacements de déverrouillage h et de réarmement K communiquées au verrou 16 et respectivement au troisième mécanisme à déclenchement brusque 19 suivent des chemins distincts de ceux qui sont suivis par les actions de déclenchement g et respectivement d.In the block diagram shown in fig. 1 a, the unlocking h and reset K actions or displacements communicated to the latch 16 and respectively to the third abrupt release mechanism 19 follow paths distinct from those which are followed by the release actions g and respectively d.

L'invention englobe toutefois une variante représentée à la fig. 1 b dans laquelle les actions g et h et respectivement d et K sont transmises par deux voies q, q et respectivement r, r qui utilisent donc un même moyen de transmission, représenté par l'ensemble du trait continu et du trait pointillé.The invention however includes a variant shown in FIG. 1 b in which the actions g and h and respectively d and K are transmitted by two channels q, q and respectively r, r which therefore use the same means of transmission, represented by the whole of the solid line and the dotted line.

Comme dans les cas précédents, la transmission des ordres q, q et celle des ordres r, r doivent se produire sans liaison mécanique entre 11 et 17 ou entre 19 et 17 par exemple par poussée. Dans la variante illustrée, le verrou 16 transmet l'action q vers le mécanisme 17 et reçoit de ce dernier l'action q; le verrou 16 peut à son tour verrouiller soit directement le contact mobile 12, soit indirectement celui-ci, en accrochant une pièce qui lui communique le déplacement, par exemple le percuteur 28 ou une tige de transmission de l'action a.As in the previous cases, the transmission of orders q, q and that of orders r, r must occur without mechanical connection between 11 and 17 or between 19 and 17 for example by pushing. In the illustrated variant, the latch 16 transmits the action q to the mechanism 17 and receives from it the action q ; the lock 16 can in turn lock either the movable contact 12 directly, or indirectly the latter, by attaching a part which communicates the displacement to it, for example the striker 28 or an action transmission rod a.

Un mode de réalisation avantageux de l'appareil selon l'invention est représenté à la fig. 2 qui montre comment les divers organes sont respectivement répartis dans un boîtier et de quelle façon ceux-ci coopèrent entre eux.An advantageous embodiment of the apparatus according to the invention is shown in FIG. 2 which shows how the various members are respectively distributed in a housing and how they cooperate with each other.

Les mécanismes de déclenchement 31,17 et 19 ainsi que la pièce de transmission 32 sont disposés dans une région supérieure 37 du boîtier qui porte une face avant 26 et l'organe de commande locale 18 coopérant avec une échelle 33 portant l'indication des positions F, D, 0 et R.The trigger mechanisms 31, 17 and 19 as well as the transmission part 32 are arranged in an upper region 37 of the housing which carries a front face 26 and the local control member 18 cooperating with a scale 33 marked with positions F, D, 0 and R.

Les organes de commutation comportant les contacts de puissance 2, les bobines 11 et les verrous 16 sont distribués dans une région centrale 38 et entre cette région supérieure 37 et une face inférieure de fixation 25 opposée à la face avant 26.The switching members comprising the power contacts 2, the coils 11 and the latches 16 are distributed in a central region 38 and between this upper region 37 and a lower fixing face 25 opposite the front face 26.

Les principales pièces de l'électro-aimant 1 commun à tous les contacts 2 sont disposées dans une première région latérale 39 comprise entre la région 37 et la face arrière 25.The main parts of the electromagnet 1 common to all the contacts 2 are arranged in a first lateral region 39 lying between the region 37 and the rear face 25.

L'ensemble des bobines 13 et des bilames 14 est disposé dans une seconde région latérale 40 opposée à la première région latérale.The set of coils 13 and bimetallic strips 14 is arranged in a second lateral region 40 opposite the first lateral region.

Dans un mode de réalisation dérivé de la fig. 2 et représenté à la fig. 3, l'appareil comprend plusieurs sous-ensembles associés, à savoir: un socle 20 portant la face arrière 25 sur laquelle s'ouvre une multiplicité n d'alvéoles 41 aptes à recevoir des cartouches amovibles 24 comportant chacune un contact de puissance 2, une bobine 11, un percuteur 28 et un verrou 16. Une portée 42 du socle reçoit une platine mécanique 22 contenant les organes 31, 32, 17, 18 et au moins une partie, fixe ou mobile, de l'interrupteur de contrôle 4, ce qui permet un assemblage préalable facile de ces organes. Un sous-ensemble amovible 21 placé latéralement reçoit au moins une partie de l'électro-aimant 1 comprenant par exemple une culasse fixe et donnant accès à la bobine 3 de façon à permettre la rechange de celle-ci, la bobine pouvant venir également avec ce sous-ensemble. Les parties mobiles de l'électro-aimant 1 telles que l'armature 29, le ressort de rappel 36 et une pièce ou poussoir mobile solidaire de, ou entraîné par, l'armature seront alors fixées sur le socle de l'appareil de façon à se trouver en regard de l'ensemble des contacts mobiles 12 des contacts de puissance 2, des vis de réglage disposées sur ce poussoir mobile, respectivement en regard de chaque contact mobile, permettront par ailleurs d'assurer que l'actionnement de ces contacts se fasse de façon simultanée.In an embodiment derived from FIG. 2 and shown in FIG. 3, the apparatus comprises several associated sub-assemblies, namely: a base 20 carrying the rear face 25 on which a multiplicity n of cells 41 open capable of receiving removable cartridges 24 each comprising a power contact 2, a coil 11, a striker 28 and a latch 16. A bearing 42 of the base receives a mechanical plate 22 containing the members 31, 32, 17, 18 and at least one part, fixed or mobile, of the control switch 4, which allows easy prior assembly of these organs. A removable sub-assembly 21 placed laterally receives at least part of the electromagnet 1 comprising for example a fixed yoke and giving access to the coil 3 so as to allow the replacement thereof, the coil can also come with this subset. The moving parts of the electromagnet 1 such as the armature 29, the return spring 36 and a movable part or pusher integral with, or driven by, the armature will then be fixed on the base of the device so to be located opposite all of the movable contacts 12 of the power contacts 2, adjustment screws disposed on this movable pusher, respectively opposite each movable contact, will also ensure that the actuation of these contacts is done simultaneously.

Dans un schéma plus détaillé visible à la fig. 4, où les éléments qui viennent d'être décrits portent les mêmes références, est mis en oeuvre le principe de transmission symbolisé à la fig. 1 b.In a more detailed diagram visible in fig. 4, where the elements which have just been described bear the same references, the principle of transmission symbolized in FIG. 1 b.

L'électro-aimant 1 comporte une culasse fixe 44 et l'armature mobile 29 coopère avec un poussoir 45 ayant un premier bras 46 et un second bras 47. Le premier bras 46 agit sur un culbuteur 48 apte à séparer le contact mobile 12 des contacts fixes 49, 50 du contact de puissance 2. Le percuteur 28 transmet son mouvement à un second poussoir 51 pivotant retenu par un ressort 52 et ayant un premier bras 53 apte à soulever le même culbuteur 48, indépendamment de 46; un second bras 54 coopère avec une surface 55 d'un verrou 16 qui est comprimé par un ressort 56 et qui présente une extrémité de transmission de mouvement 57. Un trait pointillé entourant par 24 des pièces qui viennent d'être décrites représente le contenu de la cartouche de contact puissance 24. Lorsque la bobine 11 attire le percuteur rapide 28, le second poussoir 51 est basculé et soulève le culbuteur 48; grâce à l'effacement de l'extrémité 54, la surface 55 est libérée et le verrou 16 maintient par une portée latérale 58 le second poussoir 51 dans la position qu'il vient de prendre. En même temps, l'extrémité 57 transmet une action q au second mécanisme à déclenchement brusque 17.The electromagnet 1 comprises a fixed yoke 44 and the movable armature 29 cooperates with a pusher 45 having a first arm 46 and a second arm 47. The first arm 46 acts on a rocker arm 48 capable of separating the movable contact 12 from the fixed contacts 49, 50 of the power contact 2. The striker 28 transmits its movement to a second pivoting pusher 51 retained by a spring 52 and having a first arm 53 capable of lifting the same rocker arm 48, independently of 46; a second arm 54 cooperates with a surface 55 of a latch 16 which is compressed by a spring 56 and which has a movement transmission end 57. A dotted line surrounding by 24 parts which have just been described represents the content of the power contact cartridge 24. When the coil 11 attracts the rapid striker 28, the second pusher 51 is tilted and lifts the rocker arm 48; thanks to the erasure of the end 54, the surface 55 is released and the latch 16 maintains by a lateral bearing 58 the second pusher 51 in the position it has just taken. At the same time, the end 57 transmits an action q to the second snap mechanism 17.

Un module de protection 23 amovible contient les bilames 14 et leurs chaufferettes 58 ainsi que les bobines 13 et leurs palettes 59. Les déflections c et déplacements b sont transmis au troisième mécanisme à déclenchement brusque 19, qui comprend un poussoir 60, recevant les actions b et c, et coopérant avec un levier de verrouillage 61 soumis à un ressort 62 pour verrouiller et maintenir par son bec 63 un rebord 67 qui appartient à une tige 64. Cette dernière est comprimée par un ressort 65 et possède une extrémité 66 apte à communiquer au deuxième mécanisme à déclenchement brusque 17 une action r.A removable protection module 23 contains the bimetallic strips 14 and their heaters 58 as well as the coils 13 and their pallets 59. The deflections c and displacements b are transmitted to the third mechanism with abrupt release 19, which includes a pusher 60, receiving actions b and c, and cooperating with a locking lever 61 subjected to a spring 62 to lock and hold by its spout 63 a flange 67 which belongs to a rod 64. The latter is compressed by a spring 65 and has an end 66 capable of communicating at the second abrupt trigger mechanism 17 an action r.

Le deuxième mécanisme à déclenchement brusque 17 comporte un poussoir 68 recevant les actions q et r et coopérant avec un levier de verrouillage 69 soumis à un ressort 70 pour verrouiller par son bec 71 un rebord 72 qui appartient à une tige 73. Cette dernière est comprimée par un ressort 74 et possède, d'une part, un talon 75 apte à communiquer au premier mécanisme à déclenchement brusque 31 une action p, et présente, d'autre part, une extrémité 76 placée en regard d'une surface 77 du poussoir 68. La tige 73 présente en outre un téton extérieur 78 apte à communiquer et recevoir des actions ou mouvements j et respectivement par coopération avec une pièce mobile 32.The second abrupt trigger mechanism 17 comprises a pusher 68 receiving the actions q and r and cooperating with a locking lever 69 subjected to a spring 70 to lock by its beak 71 a flange 72 which belongs to a rod 73. The latter is compressed by a spring 74 and has, on the one hand, a heel 75 capable of communicating to the first mechanism with abrupt release 31 an action p, and has, on the other hand, an end 76 placed opposite a surface 77 of the pusher 68. The rod 73 also has an external stud 78 capable of communicating and receiving actions or movements j and respectively by cooperation with a moving part 32.

Le premier mécanisme à déclenchement brusque 31 comporte un levier de verrouillage 79 soumis à un ressort 80 qui lui donne une position de repos par appui sur une butée 81. Ce levier 79 présente un poussoir isolant 84 apte à ouvrir le contact mobile 82 de l'interrupteur de contrôle 4 et une dent de verrouillage 83 apte à coopérer avec la pièce mobile 32 pour lui communiquer et recevoir d'elle des actions m et respectivement m. La pièce mobile 32 qui est soumise au ressort de rappel 35 et qui est solidaire de l'organe de commande locale 18 présente un doigt 85 apte à coopérer avec un ressort 30 et d'autre part une multiplicité de rampes et surfaces aptes à coopérer avec la dent 83 et avec le téton 78. Dans la position de la pièce 32 correspondant à la position F de l'organe de commande locale, l'interrupteur 4 est fermé et, en présence d'un signal de tension sur les bornes 5, 6, l'armature 29 est attirée, de sorte que les contacts de puissance 2 sont également fermés; l'appareil est ainsi mis en service. Pour cette position stable, qui a été donnée par une action extérieure sur 18, une rampe 86 de 32 est appliquée élastiquement dans le sens S contre la dent 83, et est retenue par celle-ci. L'apparition d'un défaut, soit par l'action q, soit par l'action r, déclenche le deuxième mécanisme 17 dont le talon 75 soulève l'extrémité 87 du levier 79. La coopération de la dent 83 et de la rampe inclinée 86 provoque un déclenchement brusque de 31 qui ouvre l'interrupteur 4 et libère la pièce 32; dans ce mouvement, la dent 83 vient alors s'appuyer sur une surface de maintien 88 de la pièce 32, et le levier 79 est dans une position de travail pour laquelle l'interrupteur 4 reste ouvert. Lorsque le talon 75 s'est déplacé, le téton 78 a pris une position plus élevée, représentée en pointillé, qui lui permet de coopérer avec une deuxième rampe inclinée 89 lorsque celle-ci se déplace dans le sens S; la pièce 32 se trouve donc arrêtée par le téton dans une position stable D correspondant à l'apparition d'un défaut.The first abrupt release mechanism 31 includes a locking lever 79 subjected to a spring 80 which gives it a rest position by pressing on a stop 81. This lever 79 has an insulating push button 84 capable of opening the movable contact 82 of the control switch 4 and a locking tooth 83 able to cooperate with the moving part 32 to communicate to it and to receive from it actions m and respectively m. The movable part 32 which is subjected to the return spring 35 and which is integral with the local control member 18 has a finger 85 capable of cooperating with a spring 30 and on the other hand a multiplicity of ramps and surfaces capable of cooperating with the tooth 83 and with the stud 78. In the position of the part 32 corresponding to the position F of the local control member, the switch 4 is closed and, in the presence of a voltage signal on the terminals 5, 6, the armature 29 is attracted, so that the power contacts 2 are also closed; the device is thus put into service. For this stable position, which has been given by an external action on 18, a ramp 86 of 32 is applied elastically in the direction S against the tooth 83, and is retained by the latter. The appearance of a defect, either by the action q, or by the action r, triggers the second mechanism 17 whose heel 75 lifts the end 87 of the lever 79. The cooperation of the tooth 83 and the ramp tilted 86 causes a sudden trip of 31 which opens the switch 4 and releases the room 32; in this movement, the tooth 83 then comes to bear on a holding surface 88 of the part 32, and the lever 79 is in a working position for which the switch 4 remains open. When the heel 75 has moved, the nipple 78 has taken a higher position, shown in dotted lines, which allows it to cooperate with a second inclined ramp 89 when the latter moves in the direction S; the part 32 is therefore stopped by the stud in a stable position D corresponding to the appearance of a fault.

Si une action extérieure est communiquée dans le sens S à l'organe de commande 18, la rampe 89 échappe au téton, qu'elle repousse légèrement, de sorte que celui-ci, après un glissement contre une surface 90, vient buter contre le départ d'une troisième rampe inclinée 91 ; la pièce 32 se trouve alors retenue dans une position stable O correspondant à l'ouverture de l'appareil par voie extérieure. Dans cette position O le doigt 85 vient au voisinage du ressort 30. Si un mouvement de sens S est donné à la pièce 32 par l'organe de commande 18, celui-ci peut atteindre une position instable R opposée à F pour laquelle le ressort 30 est comprimé; dans ce dernier mouvement, la rampe inclinée 91 exerce sur le téton 78 une action de réarmement j qui le repousse vers le bas de la figure. Le déplacement de la tige 73 est transmis par le talon 76 à la surface 77 et au poussoir 68 qui transmet à son tour le mouvement reçu vers les extrémités 57 et 66. Le deuxième mécanisme à déclenchement brusque 17 se réarme au cours de cette opération lorsque le bec 71 s'encliquette sur le rebord 72. Les déplacements du verrou 16 et de la tige 64 permettent alors, d'une part, de déverrouiller le verrou 54 et de permettre au contact 2 de pouvoir se fermer, et, d'autre part, de réarmer le troisième mécanisme 19 si les bilames sont refroidis. Si en présence d'un bilame non refroidi un déplacement est donné à la pièce 32 de la position R vers la position F, la dent 83 du levier de verrouillage 79 restera dans une position de travail sous l'effet de la poussée P du talon 75, les mécanismes 17 et 19 n'ayant pu se réarmer. Pour cette position de travail du levier 79, la dent 83 ne peut coopérer avec la rampe 86 de sorte que l'interrupteur 4 restera ouvert et qu'aucune fermeture des contacts de puissance 2 ne pourra intervenir. La seule position stable que pourra prendre l'organe de commande locale 18 sera donc la position D, ou la position O si une action correspondante est exercée sur cet organe.If an external action is communicated in the direction S to the control member 18, the ramp 89 escapes the stud, which it pushes back slightly, so that the latter, after sliding against a surface 90, abuts against the start of a third inclined ramp 91; the part 32 is then retained in a stable position O corresponding to the opening of the device externally. In this position O the finger 85 comes in the vicinity of the spring 30. If a movement of direction S is given to the part 32 by the control member 18, the latter can reach an unstable position R opposite to F for which the spring 30 is compressed; in this last movement, the inclined ramp 91 exerts on the stud 78 a reset action j which pushes it downwards in the figure. The displacement of the rod 73 is transmitted by the heel 76 to the surface 77 and to the pusher 68 which in turn transmits the movement received towards the ends 57 and 66. The second abrupt trigger mechanism 17 resets during this operation when the spout 71 snaps onto the rim 72. The movements of the latch 16 and of the rod 64 then make it possible, on the one hand, to unlock the latch 54 and allow the contact 2 to be able to close, and, on the other hand hand, rearm the third mechanism 19 if the bimetallic strips are cooled. If in the presence of an uncooled bimetallic strip a displacement is given to the part 32 from the position R towards the position F, the tooth 83 of the locking lever 79 will remain in a working position under the effect of the push P of the heel 75, mechanisms 17 and 19 could not be reset. For this working position of the lever 79, the tooth 83 cannot cooperate with the ramp 86 so that the switch 4 will remain open and that no closing of the power contacts 2 can take place. The only stable position that the local control member 18 can take will therefore be position D, or position O if a corresponding action is exerted on this member.

Accessoirement, l'appareil peut mettre en oeuvre des mesures propres à effectuer une ouverture forcée des contacts de puissance 2, notamment en cas d'éventuelles soudures. Une telle ouverture forcée est opérée soit par voie automatique au cours d'un processus de déclenchement sur défaut, soit par une action, par exemple manuelle, sur l'organe de commande locale, entre les positions F et O. Dans ce but, la pièce 32 présente une quatrième rampe 92 apte à coopérer entre les positions F et O, avec une tige de transmission ou autre moyen 93 pour exercer sur le bras 47 du levier 45 une action comparable à celle qui est exercée par le ressort 36, mais d'intensité plus importante. Un déplacement volontaire de la pièce 32 en sens S, par action sur l'organe de commande 18, peut évidemment être donnée à partir de la position F et vers la position 0 pour mettre l'appareil hors service. Au cours de cette opération, la rampe 86 repousse la dent 83 en produisant un basculement brusque du levier qui produit l'ouverture instantanée de l'interrupteur 4.Incidentally, the device can implement measures suitable for effecting a forced opening of the power contacts 2, in particular in the event of any welds. Such forced opening is operated either automatically during a fault tripping process, or by an action, for example manual, on the local control member, between positions F and O. For this purpose, the piece 32 has a fourth ramp 92 capable of cooperating between positions F and O, with a transmission rod or other means 93 to exert on the arm 47 of the lever 45 an action comparable to that which is exerted by the spring 36, but d 'higher intensity. A voluntary movement of the part 32 in direction S, by action on the control member 18, can obviously be given from position F and towards position 0 to put the device out of service. During this operation, the ramp 86 repels the tooth 83 by producing a sudden tilting of the lever which produces the instantaneous opening of the switch 4.

Il doit, par ailleurs, être compris que si dans la fig. 4 les surfaces ou rampes 88, 86, 89, 90, 91 ont été physiquement séparées afin de rendre plus claires leurs fonctions respectives, certaines d'entre elles pourraient être combinées afin de rendre plus simple la réalisation de la pièce 32; une telle combinaison serait par exemple réalisable si la dent 83 et le téton 73 se trouvaient placés plus près l'un de l'autre ou si leurs mouvements n'étaient pas parallèles.It should also be understood that if in fig. 4 the surfaces or ramps 88, 86, 89, 90, 91 have been physically separated in order to make their respective functions clearer, some of them could be combined in order to simplify the production of the part 32; such a combination would for example be achievable if the tooth 83 and the stud 73 were placed closer to each other or if their movements were not parallel.

Les déplacements, supposés rectilignes dans la fig. 4, peuvent être obtenus à l'aide de surfaces de guidage non représentées; des déplacements le long de trajectoires voisines ou courbes pourraient également être utilisés et obtenus par des moyens connus, par exemple si la pièce 32 est un disque portant les rampes et pivotant autour d'un axe YY'.The displacements, assumed to be rectilinear in fig. 4, can be obtained using guide surfaces which are not shown; displacements along neighboring or curved trajectories could also be used and obtained by known means, for example if the part 32 is a disc carrying the ramps and pivoting about an axis YY '.

D'une façon générale, l'invention peut être réalisée à l'aide de moyens de verrouillage ou de déclenchement qui opèrent les mêmes fonctions ou qui réagissent de façon comparable à ceux qui ont été représentés schématiquement à titre d'exemple non limitatif.In general, the invention can be carried out using locking or tripping means which operate the same functions or which react in a manner comparable to those which have been shown diagrammatically by way of nonlimiting example.
