Description

L'invention se rapporte à un mécanisme d'enclenchement et de déclenchement brusques d'un interrupteur à translation, notamment du type à contacts par frottement ou à mâchoires.The invention relates to a mechanism for suddenly switching on and off a translation switch, in particular of the type with friction contacts or jaws.

La principale application visée par cet interrupteur concerne le domaine des interrupteurs de puissance industrielle.The main application targeted by this switch concerns the field of industrial power switches.

Les interrupteurs à translation sont appréciés pour leur tenue au courant de court circuit car ils présentent l'important avantage de posséder une prise latérale des contacts entre deux mâchoires, à la manière d'une pince.The translation switches are appreciated for their resistance to short circuit current because they have the important advantage of having a lateral socket for the contacts between two jaws, in the manner of a clamp.

Cette caractéristique assure un contact parfait, franc et complet dès le début de l'engagement des deux pièces, et supprime les rebondissements et battements constatés avec d'autres types de contacts lors de pointes d'intensité.This characteristic ensures perfect, frank and complete contact from the start of the engagement of the two parts, and eliminates the twists and turns observed with other types of contacts during peaks of intensity.

La réalisation type connue du mécanisme d'actionnement d'un interrupteur à translation utilise une commande à genouillère. Cette commande se compose d'une biellette solidaire par une de ses extrémités de l'axe de la pognée et montée articulée par son autre extrémité sur un axe mobile entraînant en translation le support mobile porteur des contacts. Cet axe actionne également en basculement un levier pivotant moteur équipé d'un ressort de compression qui force la biellette en positions extrêmes de basculement droite ou gauche correspondant à la fermeture ou à l'ouverture du circuit ou inversement par le seul jeu de la compression du ressort entre une position extrême et le point mort central.The known typical embodiment of the actuation mechanism of a translation switch uses a toggle control. This control consists of a rod secured by one of its ends to the axis of the handle and mounted articulated by its other end on a movable axis driving in translation the movable support carrying the contacts. This axis also actuates in tilting a pivoting motor lever equipped with a compression spring which forces the link in extreme positions of right or left tilting corresponding to the closing or the opening of the circuit or vice versa by the only play of the compression of the comes out between an extreme position and the central dead center.

La compression du ressort entre la position initiale et le point milieu provoque le basculement brusque vers la position opposée.The compression of the spring between the initial position and the midpoint causes the sudden tilting towards the opposite position.

Les documents FR-A-1 370 745, FR-A-1 591 048 et FR-A-2 040 860 déczivent des mécanismes d'actionnement simileizes à celui mentionné ci-dessus.The documents FR-A-1 370 745, FR-A-1 591 048 and FR-A-2 040 860 unscrew actuation mechanisms simileizes to that mentioned above.

Si ces types de mécanisme, appliqués à un interrupteur à déplacement latéral, permettent de tirer parti de tous les avantages de ce type d'interrupteur, ils montrens toutefois, au-de là des inconvénients d'un interrupteur purement manuel nécessitant un effort certain pour sa manoeuvre, des performances limites insuffisantes dans certains cas d'utilisation.If these types of mechanism, applied to a switch with lateral displacement, make it possible to take advantage of all the advantages of this type of switch, they show however, beyond there the disadvantages of a purely manual switch requiring a certain effort to its operation, insufficient performance limits in certain cases of use.

En effet, seule la composante transversale de la force élastique du ressort peut être exploitée pour le basculement. Or, celle-ci ne représente, au voisinage du point mort central, qu'une faible partie de sa valeur totale.In fact, only the transverse component of the elastic force of the spring can be used for tilting. However, this represents, in the vicinity of the central dead center, only a small part of its total value.

Ces interrupteurs présentent, par conséquent, une vitesse d'enclenchement ou de déclenchement limitée par les caractéristiques propres de ces types de mécanisme.These switches therefore have an on or off speed limited by the specific characteristics of these types of mechanism.

De plus, il n'est guère envisageable d'équiper ce type d'interrupteur d'un dispositif de déclenchement à distance, en raison de l'énergie de commande importante qu'il faudrait employer pour faire basculer ce mécanisme.In addition, it is hardly possible to equip this type of switch with a remote triggering device, because of the large control energy that would have to be used to toggle this mechanism.

L'invention apporte des possibilités techniques supplémentaires à ces types d'interrupteur telles que la télécommande en déclenchement à faible énergie et des performances tout à fait intéressantes en vitesse de déclenchement et d'enclenchement par un mécanisme de commande composite utilisant, pour chaque mouvement, l'énergie accumulée dans un dispositif séparé.The invention provides additional technical possibilities to these types of switch such as the low energy triggering remote control and very advantageous performance in triggering and switching speed by a composite control mechanism using, for each movement, the energy stored in a separate device.

A cet effet, l'invention se rapporte à un mécanisme d'enclenchement et de déclenchement brusques, commandé à distance, pour un interrupteur à translation comportant un barreau porte-contacts, ledit mécanisme étant constitué d'une chaîne d'articulations et caractérisé en ce que ladite chaîne se compose d'un levier de réarmement manuel à partir d'un mouvement rotatif, d'une bielle brisée et, d'un dispositif de va et vient articulé par l'une de ses extrémités sur le support mécanique de l'interrupteur et par son autre extrémité sur la bielle brisée, ledit dispositif de va et vient étant constitué d'une biellette de déclenchement portant chacune un moyen de poussée et articulées entre elles selon un axe commun solidaire du barreau porte-contacts qui se déplace le long des biellettes en parfaits mouvements de translation lorsque celles-ci viennent en position d'alignement, les moyens de poussée étant mis en tension lors de l'enclenchement pour l'un par un dispositif de fin de course et pour l'autre par un moyen de déclenchement à distance, agissant sur la bielle brisée.To this end, the invention relates to an abrupt switching on and off mechanism, remotely controlled, for a translation switch comprising a contact carrier bar, said mechanism consisting of a chain of articulations and characterized in that said chain consists of a manual reset lever from a rotary movement, a broken connecting rod and, a back and forth device articulated by one of its ends on the mechanical support of the 'switch and by its other end on the broken rod, said back and forth device consisting of a trigger rod each carrying a thrust means and hinged together along a common axis integral with the contact carrier bar which moves the along the connecting rods in perfect translational movements when they come into alignment position, the pushing means being tensioned during engagement for one by a limit switch and for the other by a remote trigger means, acting on the broken connecting rod.

Ainsi le mécanisme selon l'invention confère à l'interrupteur à translation, qui en est équipé, de multiples avantages tels que:

  • - la commande en déclenchement à distance à faible énergie;
  • - la rapidité exceptionnelle de déclenchement et d'enclenchement;
  • - la possibilité d'utiliser le même dispositif électromécanique de déclenchement pour des interrupteurs d'intensité de coupure différente allant jusqu'à de fortes valeurs;
  • - l'utilisation d'une association de moyens mécaniques de montage simple;
  • - la possibilité de déclencher manuellement;
  • - la nécessité d'une plus faible force de manoeuvre en enclenchement, en raison de ce que la force du ressort d'enclenchement ne subit aucun fractionnement en une composante longitudinale et une autre composante transversale au mouvement.
Thus the mechanism according to the invention confers on the translation switch, which is equipped with it, multiple advantages such as:
  • - the low-energy remote trigger command;
  • - the exceptional speed of triggering and switching on;
  • - the possibility of using the same electromechanical tripping device for switches of different cut-off intensity up to high values;
  • - the use of a combination of simple mechanical mounting means;
  • - the possibility of triggering manually;
  • - The need for a lower switching actuating force, due to the fact that the force of the engaging spring does not undergo any splitting into a longitudinal component and another component transverse to the movement.

Les avantages techniques et d'autres avantages sont consignés dans la description qui suit, effectuée à titre d'exemple non limitatif sur un mode d'exécution de l'invention, en référence aux dessins accompagnants dans lesquels:

  • - la figure 1 est une vue générale en plan du mécanisme d'enclenchement et de déclenchement brusques selon l'invention en position de déclenchement;

  • - les figures de 4 à 6 sont des vues schématiques en plan, représentant respectivement en position déclenchée, en position intermédiaire et en position enclenchée, le mécanisme selon l'invention.
The technical advantages and other advantages are recorded in the description which follows, given by way of nonlimiting example on an embodiment of the invention, with reference to the accompanying drawings in which:
  • - Figure 1 is a general plan view of the sudden engagement and trigger mechanism according to the invention in the trigger position;

  • - Figure 3 shows, in plan view, a broken rod of another type;
  • - Figures 4 to 6 are schematic plan views, showing respectively in the released position, in the intermediate position and in the engaged position, the mechanism according to the invention.

En se référant à la figure 1, le mécanisme selon l'invention est actionné manuellement à partir d'une poignée de manoeuvre solidaire de l'axe de commande 1. Cet axe, monté pivotant sur une platine et en rappel élastique vers la position de déclenchement, entraîne, en basculement, une bielle brisée 2 de type connu, par l'intermédiaire d'un ensemble mécanique pivotant 3.Referring to Figure 1, the mechanism according to the invention is actuated manually from an operating handle secured to the control axis 1. This axis, pivotally mounted on a plate and in elastic return to the position of tripping, causes, in tilting, a broken rod 2 of known type, by means of a pivoting mechanical assembly 3.

Cet ensemble comprend un levier d'actionnement 4 monté pivotant autour de l'axe de commande 1, par exemple par une douille 5. Ce levier 4 est monté articulé par une de ses extrémités sur la bielle brisée 2 et relié par son autre extrémité à une lumière curviligne 6 prévue dans un secteur pivotant 7, solidaire de l'axe de commande 1.This assembly comprises an actuating lever 4 mounted pivoting about the control axis 1, for example by a bushing 5. This lever 4 is articulated by one of its ends on the broken connecting rod 2 and connected by its other end to a curved light 6 provided in a pivoting sector 7, integral with the control axis 1.

La bielle brisée 2 est montée articulée dans un ensemble mécanique 8 de compression et de détente procédant par alignement des éléments du bras composite dans lequel elle est insérée. Elle coopère avec un dispositif de va et vient 9 d'enclenchement et de déclenchement en tant qu'élément articulé de liaison, permettant de réaliser l'alignement des points d'articulation en phase de compression et la zuptuze en phase de déclenchement. Elle coopère également par poussée, en fin d'alignement, avec un levier de retenue basculant 10, rappelé en position de retenue par un ressort 11, qui libère instantanément l'énergie accumulée pendant la phase de compression, en vue de provoquer l'enclenchement brusque. Ce levier comporte une extrémité avec retour dont le chant forme front d'arrêt.The broken connecting rod 2 is mounted articulated in a mechanical assembly 8 for compression and expansion proceeding by aligning the elements of the composite arm in which it is inserted. It cooperates with a back and forth engagement and trigger device 9 as an articulated connecting element, making it possible to align the articulation points in the compression phase and the zuptuze in the trigger phase. It also cooperates by pushing, at the end of alignment, with a tilting retaining lever 10, returned to the retaining position by a spring 11, which instantly releases the energy accumulated during the compression phase, in order to cause the engagement sudden. This lever has one end with return, the edge of which forms a stop front.

La bielle brisée 2 est choisie de préférence dans le mode de réalisation représenté en figure 1. Elle pourra tout aussi bien présenter les caractéristiques techniques d'un autre mode de réalisation, par exemple celui représenté en figure 3 procurant sensiblement les mêmes résultats.The broken connecting rod 2 is preferably chosen in the embodiment shown in Figure 1. It could just as easily have the technical characteristics of another embodiment, for example that shown in Figure 3 providing substantially the same results.

La bielle brisée 2 est articulée, d'une part à l'extrémité du levier d'actionnement 4 par un axe 12 et, d'autre part, à l'extrémité d'une biellette d'enclenchement 13 par l'intermédiaire d'un axe 14.The broken connecting rod 2 is articulated, on the one hand at the end of the actuating lever 4 by a pin 12 and, on the other hand, at the end of an interlocking rod 13 by means of an axis 14.

La bielle brisée utilisée est formée par deux platines parallèles telles que 15, portant un mécanisme de blocage 16, constitué des éléments suivants: un levier de blocage 17 en chien de fusil présentant une encoche réceptrice 18, un levier de déclenchement 19 pivotant à ergot d'extrémité 20 à élément rectiligne transversal de verrouillage 21 coopérant, d'une part, avec l'extrémité du levier de blocage 17 et, d'autre part, avec une gorge réceptrice 22 présentant une rampe de dégagement 23 au niveau de l'extrémité de la biellette d'enclenchement 13.The broken connecting rod used is formed by two parallel plates such as 15, carrying a locking mechanism 16, consisting of the following elements: a locking lever 17 in the rifle shape having a receiving notch 18, a trigger lever 19 pivoting with lug d end 20 with a transverse rectilinear locking element 21 cooperating, on the one hand, with the end of the locking lever 17 and, on the other hand, with a receiving groove 22 having a clearance ramp 23 at the end of the connecting rod 13.

L'autre type de bielle brisée, représenté en figure 3, ne diffère pas fondamentalement de celui déjà décrit.The other type of broken connecting rod, shown in Figure 3, does not differ fundamentally from that already described.

Elle se compose de deux chapes 24, des deux axes d'articulation 12 et 14 d'extrémité, par lesquelles elle se trouve placée dans l'ensemble mécanique de compression et de détente 8.It is made up of two yokes 24, two hinge pins 12 and 14 at the end, by which it is placed in the mechanical compression and rebound assembly 8.

L'extrémité de la biellette d'enclenchement 13 affecte une forme élargie 25 à encoche en coin 26 dans laquelle vient se loger l'extrémité d'un secteur de blocage 27 solidaire d'un levier pivotant de déclenchement 28. Le principe de fonctionnement reste identique.The end of the engagement rod 13 has an enlarged shape 25 with a corner notch 26 in which is housed the end of a blocking sector 27 secured to a pivoting trigger lever 28. The operating principle remains identical.

Pour limiter l'amplitude du mouvement de zuptuze, on a prévu ici, sur l'extrémité de la biellette d'enclenchement 13, une goupille d'arrêt 29 se déplaçant dans une lumière curviligne 30. Ladite biellette d'enclenchement 13 porte un ressort d'enclenchement 31 maintenu entre deux flasques d'extrémité 32 et 33. Elle comporte une lumière longitudinale 34 coopérant avec l'axe35 du va et vient 19 qui entraîne l'équipage mobile porte-contacts entre la position d'enclenchement et la position de déclenchement.To limit the amplitude of the zuptuze movement, there is provided here, on the end of the engagement rod 13, a stop pin 29 moving in a curvilinear lumen 30. Said engagement rod 13 carries a spring 31 engaged between two end flanges 32 and 33. It comprises a longitudinal slot 34 cooperating with the axis35 of the back and forth 19 which drives the movable contact carrier between the engagement position and the position of trigger.

La biellette est conformée en pointe à son extrémité avant, articulée sur la bielle brisée 2. Cette extrémité profilée présente une découpe laissant apparaître la gorge réceptrice 22, la rampe de dégagement 23 et une pointe 36 venant se loger dans l'encoche réceptrice 18 et bloquée dans cette position par l'élément de verrouillage 21.The link is shaped as a point at its front end, articulated on the broken rod 2. This profiled end has a cut revealing the receiving groove 22, the release ramp 23 and a point 36 which is received in the receiving notch 18 and locked in this position by the locking element 21.

Le dispositif de va et vient 9 se compose d'une deuxième biellette dite de déclenchement 37, montée articulée à l'une de ses extrémités sur un axe 38 et venant s'engager sur l'axe 35 dans une lumière 39 longitudinale permettant son déplacement transversal. La biellette de déclenchement 37 pourra comporter tout aussi bien une lumière longitudinale dans sa partie arrière, qui procurera un résultat identique.The back and forth device 9 consists of a second so-called trigger rod 37, mounted articulated at one of its ends on an axis 38 and coming to engage on the axis 35 in a longitudinal slot 39 allowing its movement transverse. The trigger rod 37 may also include a longitudinal light in its rear part, which will provide an identical result.

Elle porte un ressort de déclenchement 40 maintenu par des flasques 41 et 42.It carries a trigger spring 40 held by flanges 41 and 42.

Le mécanisme selon l'invention comporte également un dispositif de commande à distance de déclenchement sous la forme d'un levier intermédiaire de déclenchement 43 monté pivotant et actionné par un moyen de poussée 44, par exemple du type électromagnétique sous la forme d'une bobine 45 à noyau plongeur46.The mechanism according to the invention also comprises a triggering remote control device in the form of an intermediate trigger lever 43 pivotally mounted and actuated by a pushing means 44, for example of the electromagnetic type in the form of a coil. 45 with plunger 46.

Le levier intermédiaire de déclenchement 43 présente une forme générale en équerre avec un retour 47 à double rampe oblique 48 permettant une action sur le levier de déclenchement 19 à n'importe quel moment de la course.The intermediate trigger lever 43 has a generally angled shape with a return 47 with a double oblique ramp 48 allowing action on the trigger lever 19 at any time during the race.

On provoque le déclenchement à distance par une impulsion de faible énergie sur la bobine 45. Le levier 43 basculera, entraînant le levier de déclenchement 19 de la bielle brisée par contact de son ergot 20 sur la double rampe 48. On pourra, bien entendu, prévoir un autre moyen provoquant le déclenchement tel que, par exemple, une bobine de manque de tension ou tout autre transducteur électromécanique en sécurité positive ou équivalent.It triggers remotely by a low energy pulse on the coil 45. The lever 43 will tilt, causing the trigger lever 19 of the broken rod by contact of its lug 20 on the double ramp 48. We can, of course, provide another means causing tripping such as, for example, a voltage drop coil or any other electromechanical transducer in posi tive or equivalent.

L'axe 35 du va et vient 9 est solidaire de l'équipage mobile en translation portant les contacts à mâchoires de l'interrupteur. Il pourra présenter une base plus épaisse sur laquelle vient en appui de blocage l'extrémité du levier de retenue.The axis 35 of the back and forth 9 is integral with the movable unit in translation carrying the jaw contacts of the switch. It may have a thicker base on which the end of the retaining lever abuts.

On décrira ci-après, les différentes phases de fonctionnement du mécanisme selon l'invention, en se référant plus particulièrement aux figures de4à6.The different phases of operation of the mechanism according to the invention will be described below, with particular reference to Figures de4à6.

On procède à l'enclenchement en agissant sur la poignée de manoeuvre pour amener les axes d'articulation 1, 12 et 14 de la bielle brisée 2 et celui du va et vient en alignement.One engages by acting on the operating handle to bring the hinge pins 1, 12 and 14 of the broken rod 2 and that of the back and forth in alignment.

La rotation de la poignée engendre, par l'intermédiaire de la bielle brises 2 à l'état bloqué, un effort de type longitudinal. La bielle brisée 2 reste à l'état bloqué et transmet l'effort au ressort d'enclenchement 31 porté par la biellette d'enclenchement 13. L'effort de poussée se transmet au ressort d'enclenchement 31 qui bute, par son flasque d'extrémité 32 contre l'axe 35 du dispositif de va et vient 9 retenu dans cette position par l'extrémité du levier 10 de retenue. La compression se poursuit par le pivotement du levier d'actionnement 4.The rotation of the handle generates, via the breeze rod 2 in the locked state, a longitudinal type force. The broken connecting rod 2 remains in the locked state and transmits the force to the engagement spring 31 carried by the engagement rod 13. The pushing force is transmitted to the engagement spring 31 which abuts, by its flange d end 32 against the axis 35 of the reciprocating device 9 retained in this position by the end of the retaining lever 10. The compression continues with the pivoting of the actuation lever 4.

Pendant toute cette phase, le déplacement de la bielle brisée 2 et, corrélativement, de la biellette d'enclenchement 13, se traduit, par la compression du ressort d'enclenchement 31 entre les deux flasques et simultanément du ressort de déclenchement 40 jusqu'à ce que le chant de ladite bielle brisée 2 bute contre le levier de retenue 10 et l'entraîne en basculement de dégagement. L'axe 35, ainsi libéré, se déplace brusquement jusqu'à la position d'enclenchement sous l'effet de la poussée du ressort. Pendant ce mouvement, il se déplace dans la lumière 39 jusqu' à la position d'enclenchement.During this entire phase, the displacement of the broken connecting rod 2 and, correspondingly, of the engagement rod 13, results in the compression of the engagement spring 31 between the two flanges and simultaneously of the trigger spring 40 to that the edge of said broken connecting rod 2 abuts against the retaining lever 10 and causes it to tilt release. The axis 35, thus released, suddenly moves to the engaged position under the effect of the spring thrust. During this movement, it moves in the lumen 39 to the position of engagement.

Le déclenchement est produit par une impulsion sur le dispositif 44, par exemple à bobine et à noyau plongeur, ou tout autre moyen équivalent. Le déplacement du noyau entraîne le basculement du levier intermédiaire de déclenchement 43 dont la double rampe oblique 48 entre en contact avec l'ergot 20 du levier de déclenchement 19. Ce dernier pivote vers l'avant en amenant son élément transversal de blocage 21 en position de dégagement. Le levier de blocage 17 s'ouvre et libère la pointe 36 de la biellette d'enclenchement pour sa rotation. La zuptuze de la liaison rectiligne se produit avec projection de la bielle à l'extérieur. Ce mouvement est favorisé par le ressort de déclenchement 40 qui se détend et provoque le déclenchement brusque par le déplacement de l'axe 35 en position extrême opposée.The trigger is produced by an impulse on the device 44, for example a coil and a plunger, or any other equivalent means. The displacement of the core causes the intermediate trigger lever 43 to tilt, the oblique double ramp 48 of which comes into contact with the lug 20 of the trigger lever 19. The latter pivots forward by bringing its transverse locking element 21 into position of clearance. The locking lever 17 opens and releases the tip 36 of the interlocking rod for its rotation. The zuptuze of the rectilinear connection occurs with projection of the rod outside. This movement is favored by the trigger spring 40 which relaxes and causes the sudden trigger by the displacement of the axis 35 in the opposite extreme position.

Le levier de retenue 10 est rappelé en position de blocage dès la fin du déclenchement par le ressort 11. Il suffit alors de manoeuvrer la poignée pour entraîner la bielle brisée 2 en blocage puis en alignement pour provoquer un nouvel enclenchement.The retaining lever 10 is returned to the blocking position as soon as the spring 11 triggers. It then suffices to maneuver the handle to drive the broken connecting rod 2 into blocking then into alignment to cause a new engagement.

Claims (5)

1. Mechanism for the sudden interlocking and tripping by remote control of a circuit-breaker of the translatory type, comprising a contact-carrying bar, the said mechanism consisting of a chain of articulations and characterised in that the said chain is composed of a lever (4) for manual resetting with a rotary movement, a broken connecting rod (2) and a reciprocating device (9) articulated at one of its ends (38) on the mechanical support of the circuit breaker and at its other end (14) on the broken connecting rod (2), the said reciprocating device (9) being constituted by an interlocking rod (31) and a tripping rod (37), each carrying a thrust means and articulated inter se on a common spindle (35) rigid with the contact carrying bar which moves along the rods with perfect translatory movements, when these latter are in a position of alignment, the thrust means being tensioned upon interlock: one by an end-of-travel device and the other by a remote tripping means acting on the broken connecting rod (2).
2. Mechanism according to Claim 2, characterised in that the interlocking rod (31) comprises a median longitudinal slot (34) having closed ends and in that the tripping rod (37) comprises a median longitudinal slot (39) which is open at one end, the said rods carrying thrust and compression springs for interlocking or tripping of the circuit breaker by relative displacement of the spindle (35) along the slots or rods in relation to the said spindle (35).
3. Mechanism according to Claim 1, characterised in that the end of travel device is a rocker- type retaining lever (10) mounted to be returned elastically to the locking position, the end of which performs an engaging and disengaging function, remaining in locked contact with the spindle (35) throughout the compression phase of the interlocking spring and releasing it under the thrusting action of the broken connecting rod (2) when this latter has reached the alignment position for its sudden movement along the slot (39) as far as its interlocking position.
4. Mechanism according to Claim 1, characterised in that the remote interlocking means is an electro-mechanical or electro-magnetic device, displacement of the movable part of which brings about pivoting of an intermediate lever (43) which operates the lever for tripping the broken connecting rod (2).
5. Mechanism according to Claims 1 and 4, characterised in that remote tripping means is of the mechanical connection type, comprising a chain, rod or lever.
