Description

La présente invention se rapporte à un appareil interrupteur de protection pourvu de pôles de puissance dont les contacts mobiles sont portés par un porte-contacts, d'un ensemble de protection à déclenchement magnétique et/ou thermique susceptible de déceler les surcharges ou surintensités sur chaque chemin de courant de pôle et d'un mécanisme de commande pouvant être manoeuvré par un bouton de commande manuelle, ce mécanisme comprenant un levier magnétique à aimant permanent coopérant d'une part avec une palette magnétisable de manoeuvre des contacts et d'autre part une palette magnétisable de déclenchement dont le mouvement est contrôlé par l'ensemble de protection.The present invention relates to a protective switch device provided with power poles, the movable contacts of which are carried by a contact carrier, of a protective assembly with magnetic and / or thermal tripping capable of detecting overloads or overcurrents on each pole current path and a control mechanism which can be operated by a manual control button, this mechanism comprising a magnetic lever with permanent magnet cooperating on the one hand with a magnetizable pallet for operating the contacts and on the other hand a magnetizable trigger pallet whose movement is controlled by the protection assembly.

Les appareils interrupteurs de protection comportent un pont de contacts susceptible d'être déplacé par rapport aux contacts fixes. En cas de défaut électrique sur un des pôles, un ensemble de déclenchement magnétique et/ou thermique est susceptible de provoquer l'ouverture des contacts. Cet ensemble de déclenchement agit sur les contacts par l'intermédiaire d'un mécanisme de commande (appelé aussi "serrure") qui peut par ailleurs être actionné manuellement par un bouton de commande manuelle.Protection switch devices have a contact bridge that can be moved relative to the fixed contacts. In the event of an electrical fault on one of the poles, a magnetic and / or thermal tripping assembly may cause the contacts to open. This trigger assembly acts on the contacts by means of a control mechanism (also called a "lock") which can also be actuated manually by a manual control button.

Un contacteur-disjoncteur comprend, pour déplacer les contacts, des moyens de commande manuelle, des organes déclencheurs magnétiques et/ou thermiques de commande automatique sur défaut et un électroaimant de commande automatique normale. Un disjoncteur-moteur comprend, pour déplacer les contacts, des moyens similaires, mais pas d'électroaimant.A contactor-circuit breaker comprises, for moving the contacts, manual control means, magnetic and / or thermal trip members for automatic control on fault and a normal automatic control electromagnet. A motor circuit breaker includes similar means for moving the contacts, but no electromagnet.

Des mécanismes de commande de type magnétique sont décrits dans le brevet français 1.464.396 et le brevet anglais 1.355.035. Ils comprennent un aimant permanent qui coopère avec une armature déplacée par un déclencheur et avec une armature solidaire du contact mobile. Le rapprochement de l'armature associée au déclencheur libère l'armature solidaire du contact mobile. Pour réaliser un appareil à plusieurs pôles, il faut autant de mécanismes à aimant que de pôles.Magnetic type control mechanisms are described in French patent 1,464,396 and English patent 1,355,035. They include a permanent magnet which cooperates with an armature displaced by a trigger and with an armature integral with the movable contact. The approximation of the armature associated with the release releases the armature integral with the movable contact. To make a device with several poles, you need as many magnet mechanisms as there are poles.

La présente invention a pour but de fournir un mécanisme de commande de type magnétique susceptible d'être monté indifféremment dans un contacteur-disjoncteur, un disjoncteur-moteur ou autres appareils interrupteurs de protection analogues. L'invention a aussi pour but d'engendrer une ouverture et une fermeture brusque des contacts quel que soit l'appareil sur lequel est monté le mécanisme.The object of the present invention is to provide a magnetic type control mechanism capable of being mounted indifferently in a contactor-circuit breaker, a motor circuit breaker or other similar protective switch devices. The invention also aims to cause an abrupt opening and closing of the contacts whatever the device on which the mechanism is mounted.

L'appareil selon l'invention est caractérisé par le fait que le mécanisme comporte des moyens pour commander, en commande manuelle, soit l'ouverture directe des contacts de puissance d'un disjoncteur ou similaire, soit, après retournement du bouton de commande manuelle, l'ouverture d'un contact auxiliaire permettant d'interrompre le courant dans la bobine de l'électroaimant de commande d'un contacteur-disjoncteur ou similaire.The apparatus according to the invention is characterized in that the mechanism includes means for controlling, by manual control, either the direct opening of the power contacts of a circuit breaker or the like, or, after turning the button manual control, the opening of an auxiliary contact making it possible to interrupt the current in the coil of the electromagnet controlling a contactor-circuit breaker or the like.

Selon une caractéristique, le mécanisme comprend un arbre de commande rotatif solidaire du bouton de commande manuelle et autour duquel peut pivoter le levier magnétique qui coopère d'un côté avec la palette de déclenchement et de l'autre côté avec la palette de manoeuvre des contacts .According to one characteristic, the mechanism comprises a rotary control shaft secured to the manual control button and around which the magnetic lever can pivot, which cooperates on one side with the triggering pallet and on the other side with the contact handling pallet .

Selon une autre caractéristique, l'arbre de commande est solidaire d'un balancier relié élastiquement à une manivelle pouvant pivoter librement autour de l'arbre de commande et susceptible d'actionner le contact bobine.According to another characteristic, the control shaft is integral with a pendulum resiliently connected to a crank which can pivot freely around the control shaft and capable of actuating the coil contact.

Selon une autre caractéristique, le mécanisme comporte un verrou pouvant pivoter autour d'un axe et présentant un cran d'arrêt dans lequel peut s'engager un pion de verrouillage du levier magnétique.According to another characteristic, the mechanism comprises a lock which can pivot around an axis and having a stop notch in which a pin for locking the magnetic lever can engage.

Le mécanisme de commande selon l'invention est destiné à équiper un appareil interrupteur de protection du type contacteur-disjoncteur tel que celui de la figure 1 ou du type disjoncteur-moteur tel que celui de la figure 2.The control mechanism according to the invention is intended to equip a protective switch device of the contactor-circuit breaker type such as that of FIG. 1 or of the motor circuit breaker type such as that of FIG. 2.

Un tel appareil comprend un ou plusieurs pôles de puissance 1 dont les parties fixes et mobiles supportant les contacts séparables sont associées à des chemins conducteurs. Ces pôles sont logés dans un boîtier 2.Such an apparatus comprises one or more power poles 1 whose fixed and mobile parts supporting the separable contacts are associated with conductive paths. These poles are housed in a housing 2.

Un seul pôle 1, de type à double coupure, est représenté sur les figures 1 et 2 de manière à simplifier les dessins. Pour chaque pôle 1, des conducteurs 3 relient les bornes de raccordement aux contacts fixes, les contacts mobiles associés étant portés par un pont de contacts mobile 4. Ce pont de contacts 4 coopère avec les contacts fixes pour établir ou interrompre le passage du courant de puissance entre les bornes de raccordement.A single pole 1, of the double break type, is shown in FIGS. 1 and 2 so as to simplify the drawings. For each pole 1, conductors 3 connect the connection terminals to the fixed contacts, the associated mobile contacts being carried by a mobile contact bridge 4. This contact bridge 4 cooperates with the fixed contacts to establish or interrupt the flow of current from power between the connection terminals.

Un ensemble porte-contacts 5 portant les ponts de contacts 4 coulisse dans le boîtier, perpendiculairement au plan passant par les contacts fixes.A contact carrier assembly 5 carrying the contact bridges 4 slides in the housing, perpendicular to the plane passing through the fixed contacts.

Un ensemble de protection 8 à déclenchement magnétique et/ou thermique est logé, dans le boîtier, pour déceler les surcharges ou surintensités sur chaque chemin de courant associé à un pôle. Lorsque cet ensemble de protection 8 décèle une surintensité ou surcharge sur un chemin de courant, il commande, par l'intermédiaire d'un mécanisme de commande 9 et d'un palonnier de renvoi 10, l'ouverture des contacts mobiles.A protective assembly 8 with magnetic and / or thermal tripping is housed in the housing to detect overloads or overcurrents on each current path associated with a pole. When this protective assembly 8 detects an overcurrent or overload on a current path, it controls, by means of a control mechanism 9 and a deflection lever 10, the opening of the movable contacts.

Dans le contacteur-disjoncteur illustré à la figure 1, l'ensemble porte-contacts 5 comporte un support coulissant 6 et des coulisseaux 7 guidés dans ce support coulissant et susceptibles chacun de déplacer en translation un pont de contacts 4. Un ressort de pression des contacts tend à déplacer chaque pont de contacts 4 par rapport au support coulissant 6, dans le sens de fermeture des contacts. Le palonnier de renvoi 10 agit sur le coulisseau 7. On remarque que la liaison entre le palonnier et le coulisseau est unilatérale, de sorte que le palonnier n'entraîne pas le coulisseau dans la direction de fermeture.In the contactor-circuit breaker illustrated in FIG. 1, the contact carrier assembly 5 comprises a sliding support 6 and slides 7 guided in this sliding support and each capable of displacing in translation a contact bridge 4. A pressure spring of the contacts tends to move each contact bridge 4 relative to the sliding support 6, in the closing direction of the contacts. The deflector lifter 10 acts on the slider 7. It is noted that the connection between the lifter and the slider is unilateral, so that the lifter does not drive the slider in the closing direction.

Un électroaimant 11 est logé dans le boîtier 2 pour déplacer le porte-contacts 5. Cet électroaimant comprend un circuit magnétique fixe, une armature mobile et une bobine reliée électriquement à des bornes par des contacts auxiliaires séparables (dits contacts de bobine). Ces derniers sont commandables par le mécanisme 9 ou par action manuelle sur le bouton de commande rotatif 12 ou, en cas de défaut, par l'action de l'ensemble de protection 8. L'armature mobile de l'électroaimant est assujettie à un ressort de rappel et déplace un balancier de renvoi 111 qui est directement attelé au support 6. L'ensemble porte-contacts 5 est donc soumis au ressort de rappel de l'électroaimant. En cas d'arrêt de l'excitation de la bobine, le ressort de rappel déplace l'ensemble formé par l'armature mobile, le balancier de renvoi 111 et l'ensemble porte-contacts 5 jusqu'à une position d'ouverture (contacts ouverts).An electromagnet 11 is housed in the housing 2 to move the contact carrier 5. This electromagnet comprises a fixed magnetic circuit, a movable armature and a coil electrically connected to terminals by separable auxiliary contacts (called coil contacts). The latter are controllable by the mechanism 9 or by manual action on the rotary control button 12 or, in the event of a fault, by the action of the protective assembly 8. The movable armature of the electromagnet is subject to a return spring and moves a return beam 111 which is directly coupled to the support 6. The contact carrier assembly 5 is therefore subjected to the return spring of the electromagnet. If the coil excitation stops, the return spring moves the assembly formed by the movable armature, the return beam 111 and the contact carrier assembly 5 to an open position ( open contacts).

Dans le disjoncteur-moteur illustré à la figure 2, le palonnier 10 est lié à l'extrémité supérieure du porte-contacts 5 par l'intermédiaire d'une articulation, de manière à entraîner ce porte-contacts dans la direction d'ouverture et dans la direction de fermeture.In the motor circuit breaker illustrated in FIG. 2, the lifter 10 is linked to the upper end of the contact carrier 5 by means of an articulation, so as to drive this contact carrier in the opening direction and in the closing direction.

Le mécanisme de commande 9 est représenté en détail sur les figures 3 à 10. Il est actionné en mode manuel par un bouton rotatif 12 de commande qui est disposé sur la face avant du boîtier. Ce mécanisme présente deux platines fixées au boîtier 2 et assurant le support des pièces constituantes. Le bouton 12 de commande manuelle est monté solidaire d'un arbre de commande 14 qui est guidé en rotation par les platines fixées au boîtier. Cet arbre de commande 14 et le bouton de commande 12 peuvent pivoter de manière à occuper trois positions principales stables: une position de "marche" (contacts fermés), une position "arrêt" (contacts ouverts) ou une position intermédiaire "déclenché" (contacts ouverts sur défaut).The control mechanism 9 is shown in detail in Figures 3 to 10. It is actuated in manual mode by a rotary control button 12 which is arranged on the front face of the housing. This mechanism has two plates fixed to the housing 2 and ensuring the support of the constituent parts. The manual control button 12 is mounted integral with a control shaft 14 which is guided in rotation by the plates fixed to the housing. This control shaft 14 and the control button 12 can pivot so as to occupy three stable main positions: a "on" position (closed contacts), a "stop" position (open contacts) or an intermediate "tripped" position ( contacts open on default).

Le bouton 12 est monté dans deux positions inversées à 180° selon que le mécanisme est associé à un contacteur-disjoncteur ou à un disjoncteur-moteur. Il comprend un bossage 121 qui est actif en mode disjoncteur-moteur en poussant un levier 18 et des rainures 122, 123 qui permettent le guidage d'un pion 192.The button 12 is mounted in two 180 ° reversed positions depending on whether the mechanism is associated with a contactor-circuit breaker or with a motor circuit breaker. It includes a boss 121 which is active in motor circuit breaker mode by pushing a lever 18 and grooves 122, 123 which allow the guide of a pin 192.

Le mécanisme 9 comprend un levier magnétique 15 portant un aimant permanent et deux palettes en matériau magnétique doux. Le levier magnétique 15 est monté pivotant, autour de l'arbre de commande 14. Il coopère d'un côté avec une palette de déclenchement 16 et de l'autre côté avec une palette de manoeuvre des contacts 17.The mechanism 9 comprises a magnetic lever 15 carrying a permanent magnet and two paddles made of soft magnetic material. The magnetic lever 15 is pivotally mounted around the control shaft 14. It cooperates on one side with a tripping pallet 16 and on the other side with a pallet for operating the contacts 17.

La palette de déclenchement 16, en matériau magnétique doux, est montée pivotante, autour d'un axe 161, par rapport aux platines de support et elle est soumise à un ressort 28. Elle pivote entre une position "marche" où elle est éloignée du levier magnétique 15 et une position "déclenché" où elle est en contact avec ce levier magnétique.The trigger pallet 16, made of soft magnetic material, is pivotally mounted, about an axis 161, relative to the support plates and it is subjected to a spring 28. It pivots between a "running" position where it is distant from the magnetic lever 15 and a "triggered" position where it is in contact with this magnetic lever.

La palette de déclenchement 16 est maintenue en position "marche" par une gâche de verrouillage 13 susceptible de pivoter autour d'un axe 131 en réponse au déclenchement de l'ensemble de protection 8. Après avoir été libérée de la gâche 13, la palette 16 peut pivoter sous l'action du ressort 28 pour venir en position "déclenché" au contact du levier magnétique 15.The triggering pallet 16 is held in the "on" position by a locking keeper 13 capable of pivoting about an axis 131 in response to the triggering of the protection assembly 8. After being released from the keeper 13, the pallet 16 can pivot under the action of the spring 28 to come into the "tripped" position in contact with the magnetic lever 15.

Le déplacement de la palette de déclenchement 16 est commandé par l'ensemble de protection 8. A l'apparition d'un courant de défaut, la palette de déclenchement 16 peut être libérée de la gâche 13 par l'ensemble de protection 8 de manière à venir en contact avec le levier magnétique 15.The movement of the trigger pallet 16 is controlled by the protection assembly 8. When a fault current appears, the trigger pallet 16 can be released from the keeper 13 by the protection assembly 8 so coming into contact with the magnetic lever 15.

La palette de manoeuvre 17, réalisée en matériau magnétique doux, est montée pivotante autour de l'arbre de commande 14. Elle est susceptible de pivoter entre une position "marche" où elle est au contact du levier magnétique 15 et où elle est donc soumise à l'attraction de l'aimant permanent et une position "déclenché" ou "arrêt" où elle est éloignée de ce levier 15.The operating pallet 17, made of soft magnetic material, is pivotally mounted around the control shaft 14. It is capable of pivoting between an "on" position where it is in contact with the magnetic lever 15 and where it is therefore subjected to the attraction of the permanent magnet and a "triggered" or "stop" position where it is distant from this lever 15.

L'arbre de commande 14 du mécanisme qui porte le bouton rotatif 12 de commande manuelle est solidaire d'un balancier 22. L'ensemble constitué du balancier 22, de l'arbre 14 et du bouton de commande 12 est relié par un ressort de traction 23 à une manivelle 24 qui peut pivoter librement, autour de l'arbre de commande 14, entre deux positions. Le ressort 23 est monté entre un doigt 221 solidaire du balancier 22 et un doigt 241 solidaire de la manivelle 24. Cette manivelle 24 peut déplacer un coulisseau 29 portant un contact bobine 252.The control shaft 14 of the mechanism which carries the rotary button 12 for manual control is integral with a balance 22. The assembly consisting of the balance 22, the shaft 14 and the control button 12 is connected by a spring of traction 23 to a crank 24 which can pivot freely, around the control shaft 14, between two positions. The spring 23 is mounted between a finger 221 secured to the balance 22 and a finger 241 secured to the crank 24. This crank 24 can move a slider 29 carrying a coil contact 252.

Le mécanisme comporte un verrou 20 qui peut pivoter autour d'un axe 201 et est pourvu d'une portée 202 et d'un cran d'arrêt 203 dans lequel peut s'engager un pion de verrouillage 151 du levier 15.The mechanism comprises a lock 20 which can pivot around an axis 201 and is provided with a bearing surface 202 and a stop notch 203 in which a locking pin 151 of the lever 15 can engage.

Le mécanisme comporte un levier 18 qui est monté pivotant autour d'un axe 181. En version disjoncteur-moteur, le pivotement du levier 18 provoque le déplacement d'une pièce intermédiaire 21 articulée autour d'un axe 211 et cette pièce 21 agit sur la palette de manoeuvre 17. Dans un contacteur-disjoncteur, le levier 18 sert à assurer la positivité d'ouverture du contact bobine.The mechanism comprises a lever 18 which is pivotally mounted around an axis 181. In the motor circuit breaker version, the pivoting of the lever 18 causes the displacement of an intermediate part 21 articulated around an axis 211 and this part 21 acts on the operating pallet 17. In a contactor-circuit breaker, the lever 18 serves to ensure the opening positivity of the coil contact.

La pièce intermédiaire 21 possède une portée 212 et est soumise à un ressort 213. Un ressort non représenté est monté entre la pièce intermédiaire 21 et le palonnier 10.The intermediate piece 21 has a bearing surface 212 and is subjected to a spring 213. A spring, not shown, is mounted between the intermediate piece 21 and the lifter 10.

Le mécanisme comporte un sous-ensemble de réarmement de la palette d'ouverture 16. Ce sous-ensemble comprend (figure 6) un levier de réarmement 19 qui est monté pivotant sur un axe 153 du levier 15 et peut être déplacé en rotation, autour de cet axe 153, par un pion 192 sur lequel agit le bouton de commande 12 par l'une ou l'autre des rainures 122, 123. Par ailleurs un crochet 26 est monté par l'intermédiaire d'une articulation sur une platine 27 susceptible de pivoter autour de l'arbre 14. Ce crochet 26 sert à maintenir le pion 192 du levier de réarmement 19. Un pion 261 du crochet 26 est guidé dans une rainure d'une platine de support fixe du mécanisme. Ce pion 261 permet de contrôler le mouvement du crochet 26 lors de déplacements de la platine 27 en assurant le bon positionnement du pion 192 par rapport au bouton.The mechanism comprises a resetting sub-assembly of the opening pallet 16. This sub-assembly comprises (FIG. 6) a resetting lever 19 which is pivotally mounted on an axis 153 of the lever 15 and can be moved in rotation, around of this axis 153, by a pin 192 on which the control button 12 acts through one or other of the grooves 122, 123. Furthermore, a hook 26 is mounted by means of an articulation on a plate 27 capable of pivot around the shaft 14. This hook 26 serves to hold the pin 192 of the reset lever 19. A pin 261 of the hook 26 is guided in a groove of a fixed support plate of the mechanism. This pin 261 makes it possible to control the movement of the hook 26 during movements of the plate 27 while ensuring the correct positioning of the pin 192 relative to the button.

La platine 27 est soumise à un ressort agissant selon la flèche 27F sur un point d'attache 271.The plate 27 is subjected to a spring acting according to the arrow 27F on an attachment point 271.

Le fonctionnement du mécanisme monté dans un disjoncteur-moteur va maintenant être expliqué.The operation of the mechanism mounted in a motor circuit breaker will now be explained.

Dans la position "marche" représentée à la figure 3, le levier magnétique 15 est immobilisé en rotation par l'intermédiaire de son pion de verrouillage 151 qui est logé dans le cran d'arrêt du verrou 20. Le flux créé par l'aimant du levier magnétique 15 se referme dans la palette de manoeuvre 17 qui est donc liée à ce levier 15 par une force d'attraction magnétique. La palette de déclenchement 16 est bloquée par la gâche de verrouillage 13 en position "marche". Les contacts mobiles sont appliqués contre les contacts fixes (fermeture des contacts) par l'application de la pièce 21, sollicitée par le ressort 213, sur le palonnier 10.In the "on" position shown in FIG. 3, the magnetic lever 15 is immobilized in rotation by means of its locking pin 151 which is housed in the lock catch 20. The flux created by the magnet the magnetic lever 15 closes in the operating pallet 17 which is therefore linked to this lever 15 by a magnetic attraction force. The triggering pallet 16 is blocked by the locking keeper 13 in the "on" position. The movable contacts are applied against the fixed contacts (closing of the contacts) by the application of the part 21, biased by the spring 213, on the lifter 10.

Pour comprendre le fonctionnement en cas de défaut (surcharge ou court-circuit) on se référera à la figure 5. L'ensemble de protection 8 qui a détecté le défaut, fait tourner la gâche de verrouillage 13. Celle-ci libère la palette 16 de déclenchement qui, sous l'effet du ressort 28, pivote et vient alors se coller contre le levier magnétique 15. Le flux créé par l'aimant se répartit dans les palettes 17 et 16. La force exercée par l'aimant sur la palette de manoeuvre 17 devient plus faible que la force du ressort 213 agissant sur la pièce intermédiaire 21. La palette de manoeuvre 17 qui se trouve libérée se décolle du levier 15, sous l'action du ressort 213. La pièce intermédiaire 21 en pivotant fait pivoter par une saillie 214 le palonnier de renvoi 10 qui déplace l'ensemble porte-contacts 5. Les contacts de puissance s'ouvrent.To understand the operation in the event of a fault (overload or short-circuit), refer to FIG. 5. The protective assembly 8 which has detected the fault, turns the locking strike 13. This releases the pallet 16 trigger which, under the effect of the spring 28, pivots and then sticks against the magnetic lever 15. The flux created by the magnet is distributed in the pallets 17 and 16. The force exerted by the magnet on the pallet maneuver 17 becomes weaker than the force of the spring 213 acting on the intermediate part 21. The maneuvering pallet 17 which is released comes off the lever 15, under the action of the spring 213. The intermediate part 21 by pivoting rotates by a projection 214 the deflector lifter 10 which moves the contact carrier assembly 5. The power contacts open.

Simultanément, la pièce intermédiaire 21 vient, sous l'action du ressort 213 percuter la portée 202 du verrou 20 par sa portée 212. Le verrou 20 libère le levier magnétique 15 qui reste retenu par la palette de déclenchement 16 (figure 5).Simultaneously, the intermediate part 21 comes under the action of the spring 213 to strike the bearing surface 202 of the latch 20 by its bearing surface 212. The latch 20 releases the magnetic lever 15 which remains retained by the triggering pallet 16 (FIG. 5).

Pour passer de la position "déclenché" (figure 5) à la position "arrêt" (figure 7), on tourne le bouton de commande 12 qui vient appuyer sur le pion 192 et décolle le levier magnétique 15 de la palette de déclenchement 16. Le levier magnétique 15 va alors chercher la palette de manoeuvre 17 par le levier 19. Le bouton 12 fait tourner le levier de réarmement 19 qui réarme la palette de déclenchement 16 sur le gâche de verrouillage 13. Ce réarmement de la palette de déclenchement 16 sur la gâche de verrouillage 13 ne s'effectue que si le défaut a disparu.To move from the "triggered" position (Figure 5) to the "stop" position (Figure 7), turn the control button 12 which comes to press the pin 192 and takes off the lever magnetic 15 of the triggering pallet 16. The magnetic lever 15 will then seek the operating pallet 17 by the lever 19. The button 12 turns the reset lever 19 which resets the triggering pallet 16 on the locking strike 13. This resetting of the triggering paddle 16 on the locking strike 13 is carried out only if the fault has disappeared.

Pour passer de la position "marche" (figure 3) à la position "arrêt" (figure 7), on tourne , dans le sens F, le bouton de commande 12 qui fait pivoter le levier basculant 18 par l'intermédiaire du bossage 121 appartenant au bouton 12. Le levier 18 fait pivoter la pièce intermédiaire 21. Celle-ci pousse la palette de manoeuvre 17 qui se décolle du levier magnétique 15. La pièce intermédiaire 21 qui n'est plus en butée avec la palette 17 et est libérée vient pousser, sous l'effet du ressort 213, le palonnier 10 de renvoi, lequel déplace le porte-contacts 5 de manière à ouvrir les contacts. En même temps, le bouton 12 fait tourner le levier de réarmement 19 par l'intermédiaire du pion 192 pour entraîner le levier magnétique 15 afin que celui-ci s'applique sur la palette de manoeuvre 17.To pass from the “on” position (FIG. 3) to the “off” position (FIG. 7), the control button 12 is turned, in the direction F, which makes the tilting lever 18 pivot through the boss 121 belonging to the button 12. The lever 18 rotates the intermediate piece 21. The latter pushes the operating pallet 17 which comes off from the magnetic lever 15. The intermediate piece 21 which is no longer in abutment with the pallet 17 and is released comes to push, under the effect of the spring 213, the deflector lifter 10, which moves the contact carrier 5 so as to open the contacts. At the same time, the button 12 rotates the reset lever 19 by means of the pin 192 to drive the magnetic lever 15 so that it is applied to the operating pallet 17.

Pour passer de la position "arrêt" (figure 7) à la position "marche" (figure 3), on tourne le bouton de commande manuelle 12. Cette rotation ramène simultanément la palette de manoeuvre 17 et le levier magnétique 15 par le levier de réarmement 19 vers la position de marche représentée à la figure 3. Le verrou 20 vient immobiliser le pion 151 du levier magnétique 15 en position "marche".To go from the "off" position (Figure 7) to the "on" position (Figure 3), turn the manual control button 12. This rotation simultaneously brings back the operating pallet 17 and the magnetic lever 15 by the resetting 19 to the on position shown in FIG. 3. The lock 20 comes to immobilize the pin 151 of the magnetic lever 15 in the "on" position.

Le fonctionnement du mécanisme monté dans un contacteur-disjoncteur va maintenant être expliqué.The operation of the mechanism mounted in a contactor-circuit breaker will now be explained.

La position "marche" est celle de la figure 3, décrite précédemment. On notera, en se référant à la figure 4, que la position du bouton 12 est à 180° de la position en version disjoncteur-moteur. Par ailleurs, en se référant à la figure 4, la manivelle 24 agit, sous l'action du ressort 23, sur le coulisseau 29 de manière à fermer le contact bobine 251-252.The "on" position is that of FIG. 3, described above. It will be noted, with reference to FIG. 4, that the position of the button 12 is 180 ° from the position in the motor circuit breaker version. Furthermore, with reference to FIG. 4, the crank 24 acts, under the action of the spring 23, on the slide 29 so as to close the coil contact 251-252.

En cas de défaut (surcharge ou court-circuit) ou d'ouverture manuelle par le bouton 12, le fonctionnement est identique au cas précédent et aboutit au pivotement du palonnier de renvoi 10 qui déplace le(s) coulisseau(x) 7. Les contacts s'ouvrent.In the event of a fault (overload or short circuit) or manual opening by button 12, the operation is identical to the previous case and results in the pivoting of the deflector lifter 10 which moves the slide (s) 7. The contacts open.

Simultanément, la pièce intermédiaire 21 vient, sous l'action du ressort 213 percuter la portée 202 du verrou 20 par sa portée 212. Le verrou 20 libère le levier magnétique 15 retenu par la palette 16 (figure 5). En même temps, le verrou 20 entraîne, par sa portée 204, le pion 241 de la manivelle 24. Celle-ci pivote autour de l'arbre 14 et entraîne le coulisseau 29 qui ouvre les contacts bobine 251,252.Simultaneously, the intermediate piece 21 comes under the action of the spring 213 to strike the bearing surface 202 of the latch 20 by its bearing surface 212. The latch 20 releases the magnetic lever 15 retained by the pallet 16 (FIG. 5). At the same time, the bolt 20 drives, by its range 204, the pin 241 of the crank 24. The latter pivots around the shaft 14 and drives the slide 29 which opens the coil contacts 251,252.

En passant de la position "Marche" (figure 4) à la position "Déclenché" (figures 5, 6 et 9), le balancier 22 pivote vers la position "déclenché" en passant le point mort. L'ouverture du contact bobine 251-252 entraîne l'ouverture des contacts de puissance. Le levier de réarmement 19 détermine alors la position du balancier 22 et du bouton 12 (position "déclenché"). Le mécanisme entraîne donc l'ouverture rapide des contacts de puissance et l'ouverture du contact bobine sous l'effet d'une surcharge ou d'un défaut.Passing from the "On" position (Figure 4) to the "Triggered" position (Figures 5, 6 and 9), the balance 22 pivots to the "triggered" position passing neutral. The opening of the coil contact 251-252 causes the opening of the power contacts. The reset lever 19 then determines the position of the balance 22 and of the button 12 ("tripped" position). The mechanism therefore causes the rapid opening of the power contacts and the opening of the coil contact under the effect of an overload or a fault.

Pour passer de la position "déclenché" (figures 5 et 6) à la position "arrêt" (figure 8), on tourne le bouton de commande 12 qui vient appuyer sur le pion 192 et décolle le levier magnétique 15 de la palette 16. Le levier magnétique 15 va alors chercher la palette de manoeuvre 17 par le levier 19, par arc-boutement. Le bouton 12 fait tourner le levier de réarmement 19 qui réarme la palette de déclenchement 16 sur la gâche de verrouillage 13. Ce réarmement de la palette de déclenchement 16 sur la gâche de verrouillage 13 ne s'effectue que si le défaut a disparu.To pass from the "triggered" position (FIGS. 5 and 6) to the "OFF" position (FIG. 8), the control button 12 is turned which presses on the pin 192 and takes off the magnetic lever 15 from the pallet 16. The magnetic lever 15 will then seek the operating pallet 17 by the lever 19, by bracing. The button 12 rotates the reset lever 19 which resets the triggering paddle 16 on the locking strike 13. This reset of the triggering paddle 16 on the locking strike 13 is only carried out if the fault has disappeared.

Pour passer de la position "arrêt" (figure 8) à la position "marche" (figure 3), on tourne le bouton de commande manuelle 12. Cette rotation ramène simultanément la palette de manoeuvre 17 et le levier magnétique 15 par le levier de réarmement 19 vers la position de marche représentée à la figure 3. Le verrou 20 vient immobiliser le pion 151 du levier magnétique 15 en position "marche" et permet à la manivelle 24 de venir refermer les contacts bobine 251,252.To go from the "off" position (Figure 8) to the "on" position (Figure 3), turn the manual control button 12. This rotation simultaneously brings back the operating pallet 17 and the magnetic lever 15 by the resetting 19 to the operating position shown in FIG. 3. The lock 20 comes to immobilize the pin 151 of the magnetic lever 15 in the "on" position and allows the crank 24 to close the coil contacts 251,252.

Il est bien entendu que l'on peut sans sortir du cadre de l'invention imaginer des variantes et des perfectionnements de détail et de même envisager l'emploi de moyens équivalents.It is understood that it is possible without departing from the scope of the invention to imagine variants and improvements in detail and even envisage the use of equivalent means.
