Description

La présente invention concerne un coupe-circuit utilisé comme moyen de sécurité pour un circuit électrique. Les coupe-circuits sont couramment utilisés comme coupe-batteries équipant des véhicules, notamment des véhicules de transport de matières dangereuses dont les consignes de sécurité sont très strictes.The present invention relates to a circuit breaker used as safety means for an electrical circuit. The circuit breakers are commonly used as battery switches fitted to vehicles, in particular vehicles for the transport of dangerous goods, the safety instructions are very strict.

On connaít sur le marché différents types de coupe-batterie qui peuvent être à commande manuelle, pneumatique ou électromagnétique. Le coupe-batterie comprend un boítier, une embase pourvue d'au moins deux plots électriques de contact, un pont transversal de contact pouvant relier électriquement les plots de contact, un organe d'actionnement mobile axialement qui coppère mécaniquement avec le pont transversal de contact. L'organe d'actionnement mobile permet d'établir ou de supprimer la liaison électrique entre les plots de contact via le pont transversal de contact et de définir ainsi les états électriques "ON" et "OFF" du coupe-batterie.We know on the market different types of battery switch that can be manual, pneumatic or electromagnetic. The battery switch includes a box, a base provided with at least two electrical contact pads, a bridge transverse contact that can electrically connect the pads contact, an axially movable actuating member which co-operates mechanically with the transverse contact bridge. The organ actuation button enables or removes the connection electric between the contact pads via the transverse contact bridge and thus define the electrical states "ON" and "OFF" of the battery switch.

Les coupes-batteries classiques à commande électromagnétique comprennent une bobine d'excitation qui entoure une partie de l'organe d'actionnement mobile. La bobine est constamment alimentée par un courant électrique continu pour maintenir le pont transversal en contact avec les plots de contact afin d'assurer l'état électrique ON du coupe-circuit. Il suffit de supprimer le courant d'excitation de la bobine pour que le pont transversal s'éloigne des plots de contact en assurant ainsi l'état électrique OFF du coupe-circuit. Le pont transversal de contact est maintenu dans la position éloignée des plots de contact par un ressort de rappel axial agissant sur une extrémité de l'organe d'actionnement mobile (voir le document US-A-2 922 861).The classic electromagnetic-controlled battery switches include an excitation coil which surrounds part of the organ mobile actuation. The coil is constantly supplied by a direct current to maintain the cross bridge in contact with the contact pads to ensure the ON electrical state of the circuit breaker. Just remove the excitation current from the coil so that the transverse bridge moves away from the contact pads in thus ensuring the OFF electrical state of the circuit breaker. The bridge transverse contact is kept in the position away from the studs contact by an axial return spring acting on one end of the mobile actuating member (see document US-A-2,922,861).

A cause de la nécessité d'un courant électrique alimentant en permanence la bobine d'excitation pour maintenir le coupe-batterie en position ON, la consommation énergétique du coupe-batterie est élevée. En outre, en cas de défaillance du système d'alimentation du courant électrique pour la bobine, le coupe-batterie est automatiquement changé en position OFF dû à la force mécanique exercée sur l'organe mobile d'actionnement par le ressort de rappel. Un tel changement intempestif d'état électrique du coupe-batterie peut être grave de conséquence pour le circuit électrique auquel est relié le coupe-batterie, puisque l'alimentation électrique dudit circuit est ainsi interrompue.Because of the need for an electric current supplying permanently the excitation coil to keep the battery switch in ON position, the energy consumption of the battery switch is high. In addition, in the event of a failure in the supply system of the electric current for the coil, the battery switch is automatically changed to OFF position due to mechanical force exerted on the movable actuating member by the return spring. A such untimely change of electrical state of the battery switch may be of serious consequence for the electrical circuit to which the battery switch, since the electrical supply of said circuit is thus interrupted.

La présente invention a pour objet de remédier aux inconvénients susmentionnés en proposant un coupe-circuit dont le fonctionnement est fiable et implique une faible consommation d'énergie.The object of the present invention is to remedy the drawbacks above by proposing a circuit breaker whose operation is reliable and involves low energy consumption.

L'invention a également pour objet un coupe-circuit à commande électromagnétique pour lequel le changement d'état électrique est réalisé par une simple impulsion électrique dans la bobine d'excitation.The subject of the invention is also a control circuit breaker electromagnetic for which the change of electrical state is produced by a simple electrical pulse in the coil of excitement.

Un autre objet de l'invention est de supprimer le courant électrique de maintien dans la bobine d'excitation lorsque le coupe-circuit est dans un état électrique ON ou OFF.Another object of the invention is to suppress the current electric holding in the excitation coil when the circuit breaker is in an electric ON or OFF state.

Le coupe-circuit selon l'invention comprend un boítier, une embase pourvue d'au moins deux plots électriques de contact, un pont transversal de contact situé au dessus des plots de contact et capable d'entrer en contact avec lesdits plots de contact, et des moyens d'actionnement du pont transversal qui établit ou supprime électriquement la liaison entre les plots de contact, les moyens d'actionnement comprenant un organe mobile axialement d'actionnement coopérant mécaniquement avec le pont transversal de contact et pourvu d'un axe transversal, une bobine électrique fixe pour générer une force électromagnétique agissant axialement sur l'organe mobile vers les plots de contact, un ressort de rappel agissant axialement sur l'organe mobile en l'éloignant des plots de contact, une rampe inférieure et une rampe supérieure montées fixes en regard l'une de l'autre et coopérant avec l'axe transversal respectivement pendant la première partie et la dernière partie de la phase d'actionnement du pont de contact, la rampe supérieure définissant deux états de repos de l'axe transversal correspondant à deux états électriques du coupe-circuit. Le coupe-circuit comprend deux galets roulants (19) montés sur l'axe transversal (18), les rampes inférieure et supérieure comprenant chacune des surfaces de guidage qui séparent deux butées mécaniques angulaires consécutives pour le galet roulant, chaque butée mécanique de l'une des rampes étant en vis-à-vis axialement d'une surface de guidage de l'autre rampe, les surfaces de guidage et de butée angulaire étant réparties de façon alternée circonférentiellement. Les rampes supérieure et inférieure sont réalisées sur deux parties tubulaires de même diamètre et offrent des surfaces de guidage et des surfaces de butée angulaire pour les galets roulants. Les surfaces de butée angulaire de la rampe supérieure sont situées axialement au-dessus des surfaces de guidage de la rampe inférieure et vice versa.The circuit breaker according to the invention comprises a housing, a base provided with at least two electrical contact pads, a bridge transverse contact located above the contact pads and capable of coming into contact with said contact pads, and means of actuating the transverse bridge which establishes or eliminates electrically the connection between the contact pads, the actuating means comprising a movable member axially actuated mechanically cooperating with the transverse contact bridge and provided with a transverse axis, a fixed electric coil to generate a force electromagnetic acting axially on the moving member towards contact pads, a return spring acting axially on the movable member away from the contact pads, a ramp lower and an upper ramp mounted fixed in look at each other and cooperating with the transverse axis respectively during the first part and the last part of the contact bridge actuation phase, the upper ramp defining two rest states of the corresponding transverse axis two electrical states of the circuit breaker. The circuit breaker comprises two rolling rollers (19) mounted on the transverse axis (18), the lower and upper ramps each comprising guide surfaces which separate two mechanical stops consecutive angles for the roller, each mechanical stop of one of the ramps facing axially one guide surface of the other ramp, the guide surfaces and angular stopper being distributed alternately circumferentially. The upper and lower ramps are made on two tubular parts of the same diameter and provide guide surfaces and angular stop surfaces for the rollers. The angular abutment surfaces of the upper ramp are located axially above the guide surfaces of the lower ramp and vice versa.

    • Comme illustré sur les figures 1 et 2, le coupe-circuit comprend un boítier 1 qui est monté à sa partie inférieure sous forme de clip sur le pourtour horizontal d'une embase 2. Le boítier 1 peut être réalisé en tôle métallique ou en matière plastique rigide. L'embase 2 est réalisée en matière plastique rigide non conductrice d'électricité, par exemple en bakélite. A travers l'embase 2 sont fixées deux bornes électriques de sortie 3 comportant chacune un plot électrique de contact 3a et deux ou trois bornes électriques 4 de réception de l'information de commande. Les bornes de sortie 3 sont reliées respectivement à un circuit électrique non représenté et à une batterie d'alimentation non représentée via des câbles électriques non représentés.As illustrated in Figures 1 and 2, the circuit breaker includes a housing 1 which is mounted at its lower part in the form of a clip on the horizontal periphery of a base 2. The housing 1 can be made in sheet metal or rigid plastic. Base 2 is made rigid plastic material which does not conduct electricity, for example Bakelite. Through the base 2 are fixed two electrical terminals output 3 each comprising an electrical contact pad 3a and two or three electrical terminals 4 for receiving information from ordered. The output terminals 3 are respectively connected to a electrical circuit not shown and a supply battery not represented by electrical cables not shown.

    A l'intérieur du boítier se trouvent des moyens d'actionnement 5 pour un pont électrique de contact 6 en vue de déplacer ce dernier dans le sens vertical sur les dessins. Lorsque le pont horizontal 6 est en contact avec les plots électriques 3a, les bornes électriques 3 sont reliées entre elles électriquement. Alors le coupe-circuit est à l'état électrique ON, c'est-à-dire en position fermée. Lorsque le pont transversal 6 n'est pas en contact avec les plots électriques 3a, les bornes électriques 3 ne sont plus reliées électriquement l'une à l'autre. Le coupe-circuit se trouve alors à l'état électrique OFF, c'est-à-dire en position ouverte.Inside the housing are actuation means 5 for an electric contact bridge 6 in order to move the latter vertically in the drawings. When horizontal bridge 6 is in contact with the electrical pads 3a, the electrical terminals 3 are electrically interconnected. Then the circuit breaker is in the state electric ON, i.e. in the closed position. When the bridge transverse 6 is not in contact with the electrical pads 3a, the electrical terminals 3 are no longer electrically connected to each other. The circuit breaker is then in the OFF electrical state, i.e. in open position.

    Les moyens d'actionnement 5 du pont électrique de contact 6 comprennent une bobine cylindrique 7 délimitée intérieurement par un élément cylindrique 8 réalisé en matériau non magnétique, et extérieurement par une carcasse métallique 9 fixée au-dessus d'un support métallique supérieur 10 au moyen de vis 11. Le support supérieur 10 est monté à son tour au-dessus d'un support métallique inférieur 12 au moyen de vis 13 pour être solidarisé sur l'embase 2.The actuating means 5 of the electric contact bridge 6 comprise a cylindrical coil 7 delimited internally by a cylindrical element 8 made of non-magnetic material, and externally by a metal carcass 9 fixed above a upper metal support 10 by means of screws 11. The support upper 10 is mounted in turn above a metal support lower 12 by means of screws 13 to be secured to the base 2.

    L'élément cylindrique non magnétique 8 délimite un passage cylindrique vertical 8a dans lequel est logé un noyau fixe 14 tubulaire dont l'extrémité inférieure est en butée axiale sur les bords d'une ouverture centrale 15 du support métallique supérieur 10. Dans le passage cylindrique 8a se trouve également un noyau mobile 16 dans lequel est fixée concentriquement l'extrémité supérieure d'un axe de commande 17. L'axe de commande 17 s'étend verticalement au travers du noyau fixe 14. En dessous de l'ouverture centrale 15 du support métallique supérieur 10 se trouve un axe transversal 18 porte-galet monté dans un trou diamétral de l'axe de commande 17 et pourvu à chaque extrémité d'un galet roulant 19. L'axe de commande 17 présente ensuite un rétrécissement cylindrique en dessous de l'axe porte-galet 18 de façon à offrir un épaulement radial 20 constituant une surface d'appui pour un ressort hélicoïdal 21 appelé "ressort principal de contact", l'autre extrémité du ressort principal 21 étant en appui sur un élément intermédiaire cylindrique 22 en matière plastique non conductrice d'électricité qui délimite un passage cylindrique pour la partie inférieure de l'axe de commande 17 au travers du pont transversal de contact 6. L'extrémité inférieure de l'axe de commande 17 présente la forme d'un collet radial 23 qui offre sa surface supérieure au contact de l'élément intermédiaire 22, et sa surface inférieure au contact de l'extrémité supérieure d'un second ressort hélicoïdal 24 appelé "ressort de rappel", l'extrémité inférieure du ressort de rappel 24 étant centrée et guidée dans un évidement central 25 de l'embase 2.The non-magnetic cylindrical element 8 delimits a passage vertical cylindrical 8a in which is housed a fixed tubular core 14 whose lower end is in axial abutment on the edges of a central opening 15 of the upper metal support 10. In the cylindrical passage 8a is also a movable core 16 in which is fixed concentrically the upper end of an axis of control 17. The control axis 17 extends vertically through of the fixed core 14. Below the central opening 15 of the support upper metal 10 is a transverse axis 18 roller carrier mounted in a diametrical hole of the control axis 17 and provided with each end of a roller 19. The control axis 17 then has a cylindrical narrowing below the axis roller holder 18 so as to provide a radial shoulder 20 constituting a bearing surface for a helical spring 21 called "spring main contact ", the other end of the main spring 21 being support on a cylindrical intermediate element 22 made of plastic non-conductive of electricity which delimits a cylindrical passage for the lower part of the control axis 17 across the bridge transverse contact 6. The lower end of the control shaft 17 has the shape of a radial collar 23 which offers its surface higher in contact with the intermediate element 22, and its surface lower in contact with the upper end of a second spring helical 24 called "return spring", the lower end of the return spring 24 being centered and guided in a central recess 25 of base 2.

    L'embase 2 peut présenter deux cloisons sensiblement verticales 2a qui définissent un passage pour permettre le mouvement vertical du pont électrique de contact 6 en le protégeant contre un pivotement intempestif autour de l'axe de commande 17, un tel pivotement pouvant dévier les extrémités du pont 6 par rapport aux plots de contact 3a.The base 2 may have two substantially vertical partitions 2a which define a passage to allow the vertical movement of the electric contact bridge 6, protecting it against swiveling untimely around the control axis 17, such a pivoting can deflect the ends of the bridge 6 with respect to the studs contact 3a.

    Le support métallique supérieur 10 présente une portion tubulaire 10a s'étendant vers le bas concentriquement à son ouverture centrale 15. Cette portion tubulaire 10a présente des surfaces inclinées pour constituer une rampe supérieure pour le guidage et l'arrêt des galets 19. De même, le support métallique inférieur 12 présente une portion tubulaire centrale 12a de même diamètre que la portion tubulaire 10a et présentant des surfaces de guidage et de butée angulaire pour les galets 19 et constitue la rampe inférieure.The upper metal support 10 has a tubular portion 10a extending downward concentrically to its central opening 15. This tubular portion 10a has inclined surfaces for constitute an upper ramp for guiding and stopping the rollers 19. Similarly, the lower metal support 12 has a portion central tubular 12a of the same diameter as the tubular portion 10a and having guide and angular abutment surfaces for the rollers 19 and constitutes the lower ramp.

    Sur le boítier 1 du coupe-circuit se trouve une unité de commande 26 qui commande l'excitation électrique de la bobine 7 via les liaisons 27. Lorsque la bobine 7 est excitée par un courant électrique, elle génère un champ magnétique dont les lignes de champ passent dans un circuit magnétique formé par le noyau mobile 16, le noyau fixe 14, le support métallique supérieur 10 et la carcasse métallique 9. De cette façon, une force électromagnétique est crééeet agit sur le noyau mobile 16 axialement vers le bas, l'axe de commande 17 solidaire du noyau mobile 16 étant alors entraíné également vers le bas.On the box 1 of the circuit breaker is a control unit 26 which controls the electrical excitation of the coil 7 via the connections 27. When the coil 7 is excited by an electric current, it generates a magnetic field whose field lines pass through a magnetic circuit formed by the movable core 16, the fixed core 14, the upper metal support 10 and the metal carcass 9. From this way, an electromagnetic force is created and acts on the nucleus movable 16 axially downward, the control axis 17 integral with the mobile core 16 then being also driven down.

    Lorsqu'on part d'une position ouverte du coupe-circuit (figures 1 et 2), les deux galets roulants 19 sont plaqués sur la rampe supérieure 10a par le ressort de rappel 24 en une première position stable P1 (figure 3) définie par une surface de butée angulaire 10b. Une impulsion électrique donnée à la bobine 7 fait déplacer le noyau mobile 16 vers le noyau fixe 14. L'axe de commande 17 solidaire du noyau mobile 16 se déplace axialement vers le bas et met en contact le pont électrique 6 avec les deux plots de contact 3a.When starting from an open position of the circuit breaker (Figures 1 and 2), the two rollers 19 are pressed against the upper ramp 10a by the return spring 24 in a first stable position P1 (Figure 3) defined by an angular abutment surface 10b. A electrical impulse given to coil 7 moves the core mobile 16 towards the fixed core 14. The control axis 17 secured to the movable core 16 moves axially downwards and brings the electric bridge 6 with the two contact pads 3a.

    L'axe de commande 17 qui est guidé axialement au travers le pont électrique 6 via l'élément intermédiaire 22 continue à se déplacer vers le bas en vainquant l'effort axial du ressort principal 21, ce qui augmente alors la pression de contact du pont transversal 6 sur les plots de contact 3a. Les galets roulants 19 viennent en contact avec la rampe inférieure 12a en position P2 et roulent sur la surface de guidage inclinée 12b en faisant tourner l'axe de commande 17 angulairement jusqu'à une butée mécanique 12c (surface de butée angulaire) de la rampe inférieure définissant la position P3.The control axis 17 which is guided axially across the bridge electric 6 via the intermediate element 22 continues to move towards the bottom by defeating the axial force of the main spring 21, which then increases the contact pressure of the transverse bridge 6 on the contact pads 3a. The rollers 19 come into contact with the lower ramp 12a in position P2 and roll on the surface of inclined guide 12b by rotating the control axis 17 angularly up to a mechanical stop 12c (stop surface angle) of the lower ramp defining position P3.

    L'impulsion électrique est supprimée lorsque les galets roulants 19 se trouvent en position P3. L'axe de commande 17 sous l'action combinée du ressort principal de contact 21 et du ressort de rappel 24 remonte verticalement jusqu'au contact des galets 19 sur une surface de guidage 10c de la rampe supérieure 10a, en position P4. Puis les galets 19 roulent sur la surface de guidage 10c en entraínant en rotation l'axe de commande 17 jusqu'à une position angulaire déterminée par une autre butée mécanique 10d définissant une seconde position stable P5 pour les galets 19 sur la rampe supérieure 10a. Dans cette position, le pont électrique 6 est maintenu par le ressort principal 21 en contact avec les plots électriques 3a. Le coupe-circuit est alors en position fermée.The electrical impulse is suppressed when the rollers 19 are in position P3. The control axis 17 under the action combined main contact spring 21 and return spring 24 goes up vertically until contact with the rollers 19 on a surface guide 10c of the upper ramp 10a, in position P4. Then the rollers 19 roll on the guide surface 10c driving in rotation of the control axis 17 to an angular position determined by another mechanical stop 10d defining a second stable position P5 for the rollers 19 on the upper ramp 10a. In this position, the electric bridge 6 is held by the main spring 21 in contact with the electrical pads 3a. The circuit breaker is then in the closed position.

    Une nouvelle impulsion électrique donnée à la bobine d'excitation 7 suivant le même principe que précédemment, permet aux galets roulants 19 de se trouver successivement dans les positions instables P6, P7 et P8 puis dans la position stable P1, pour passer de l'état ON à l'état OFF du coupe-circuit. Le ressort de rappel 24 monté entre l'embase 2 et l'axe de commande 17 permet à l'ensemble mobile formé par l'axe de commande 17, le pont de contact 6, l'axe porte-galet 18, les galets 19 et le noyau mobile 16 de se positionner en permanence vers la rampe supérieure 10a.A new electrical impulse given to the excitation coil 7 following the same principle as above, allows the rollers rollers 19 to be successively in unstable positions P6, P7 and P8 then in the stable position P1, to go from the ON state to OFF state of the circuit breaker. Return spring 24 mounted between the base 2 and the control axis 17 allows the mobile assembly formed by the control axis 17, the contact bridge 6, the roller carrier axis 18, the rollers 19 and the movable core 16 to position themselves permanently towards the upper ramp 10a.

    Les deux rampes supérieure 10a et inférieure 12a sont montées fixes en vis-à-vis et parfaitement positionnées en hauteur et angulairement l'une par rapport à l'autre. La rampe supérieure 10a définit plusieurs positions stables P1 et P5 pour les galets roulants 19 qui correspondent aux états électriques OFF et ON du coupe-circuit. Les positions stables P1 et P5 de hauteur différente sont décalées angulairement et alternativement l'une' de l'autre. Entre deux positions stables P1 et P5 se trouve une surface de guidage 10c sur laquelle roulent les galets 19. La différence de hauteur entre les deux positions stables P1 et P5 doit être inférieure à la valeur de l'entrefer formé entre le noyau mobile 16 et le noyau fixe 14. En outre, cette différence de hauteur doit être déterminée en fonction de l'effort de contact entre le pont électrique 6 et les plots de contact 3a quand le coupe-circuit est fermé (état ON) et de la distance d'isolement entre le pont électrique 6 et les plots de contact 3a quand le coupe-circuit est ouvert (état OFF).The two upper ramps 10a and lower 12a are mounted fixed opposite and perfectly positioned in height and angularly one relative to the other. The upper ramp 10a defines several stable positions P1 and P5 for the rollers 19 which correspond to the OFF and ON electrical states of the circuit breaker. The stable positions P1 and P5 of different height are offset angularly and alternately from one another. Between two positions stable P1 and P5 is a guide surface 10c on which rollers rollers 19. The height difference between the two positions stable P1 and P5 must be less than the value of the air gap formed between the movable core 16 and the fixed core 14. In addition, this difference height must be determined according to the contact force between the electric bridge 6 and the contact pads 3a when the circuit breaker is closed (state ON) and the isolation distance between the bridge electric 6 and contact pads 3a when the circuit breaker is open (OFF state).

    La rampe inférieure 12a coopère avec les galets roulants 19 pendant la première partie de la phase d'actionnement du pont électrique 6, et permet aux galets roulants 19 de se déplacer sur des secteurs angulaires en hélice que constituent les surfaces de guidage 12b. Lors d'une impulsion électrique d'excitation, l'axe de commande 17 se déplace axialement vers le bas dans un premier temps sous l'effet électromagnétique généré par la bobine 7, puis tourne suivant la trajectoire donnée aux galets 19 par la rampe inférieure 12a jusqu'à la butée mécanique 12c (position P3 des galets). A ce moment précis, on supprime l'excitation électrique de la bobine 7 et déclenche la dernière phase de l'actionnement qui devient automatique sous l'action des ressorts 21 et 24, pour que les galets 19 coopérant avec la rampe supérieure 10a se logent dans une des positions stables P1 et P5. Les secteurs angulaires en hélice constituant les surfaces de guidage 10c et 12b des rampes supérieure 10a et inférieure 12a présentent des inclinaisons de signes contraires par rapport à un plan transversal à l'axe de commande 17.The lower ramp 12a cooperates with the rollers 19 during the first part of the bridge activation phase electric 6, and allows the rollers 19 to move on helical angular sectors which constitute the guide surfaces 12b. During an electrical excitation pulse, the control axis 17 moves axially downward at first under the electromagnetic effect generated by the coil 7, then turns according to the trajectory given to the rollers 19 by the lower ramp 12a up to the mechanical stop 12c (position P3 of the rollers). At this precise moment, we removes electrical excitation from coil 7 and triggers the last actuation phase which becomes automatic under the action of springs 21 and 24, so that the rollers 19 cooperating with the ramp upper 10a are housed in one of the stable positions P1 and P5. The helical angular sectors constituting the guide surfaces 10c and 12b of the upper 10a and lower 12a ramps have inclinations of opposite signs with respect to a plane transverse to the control axis 17.

    La durée nécessaire des impulsions électriques à la bobine 7 peut être fixée à l'avance ou réglée à tout moment au moyen d'une interface électronique (non représentée) qui reçoit les informations de commande délivrées par les bornes de réception 4 et les transforment en un signal de régulation à l'unité de commande 26.The required duration of the electrical pulses at coil 7 can be set in advance or set at any time using an interface electronic (not shown) which receives information from command issued by reception terminals 4 and transform them as a regulation signal to the control unit 26.

    Sur la base du coupe-circuit à commande électromagnétique qu'on vient de décrire, il est possible de prévoir des options supplémentaires en vue notamment d'augmenter la fiabilité de l'actionnement du coupe-circuit. Les figures 4 et 5 offrent deux des options possibles.Based on the electromagnetic control circuit breaker that just described, it is possible to provide additional options in particular to increase the reliability of the actuation of the circuit breaker. Figures 4 and 5 offer two of the possible options.

    Par rapport au coupe-circuit illustré sur les figures 1 et 2, il suffit d'aménager la paroi supérieure la du boítier 1 en prévoyant une ouverture tubulaire 1b pour le passage de la partie supérieure du noyau mobile 16 qui sera prolongé axialement vers le haut.Compared to the circuit breaker illustrated in Figures 1 and 2, it suffices to arrange the upper wall of the housing 1 by providing a tubular opening 1b for the passage of the upper part of the core mobile 16 which will be extended axially upwards.

    Selon l'option prévue sur les figures 4a et 4b, l'extrémité supérieure 16a du noyau mobile 16 fait saillie par rapport à l'ouverture centrale tubulaire 1b de la paroi supérieure 1a du boítier, l'étanchéité entre le noyau mobile 16 et l'ouverture tubulaire 1b étant assurée au moyen d'un joint torique 16b logé dans une gorge annulaire du noyau mobile 16. Sur la surface supérieure de l'extrémité 16a du noyau mobile 16 est pratiquée une flèche d'indication qui coopère avec des inscriptions ON et OFF sur la paroi supérieure 1a du boítier, afin d'indiquer visuellement l'état électrique du coupe-circuit (figure 4b). Lorsque le système d'alimentation électrique 26 de la bobine d'excitation 7 est défaillant, il suffit que l'usager exerce manuellement une force d'appui selon la flèche 28 dans le sens vertical descendant sur l'extrémité supérieure 16a du noyau mobile 16 pour déclencher les moyens d'actionnement 5 du pont transversal de contact 6.According to the option provided in Figures 4a and 4b, the end upper 16a of the movable core 16 protrudes from the opening tubular central unit 1b of the upper wall 1a of the housing, the sealing between the movable core 16 and the tubular opening 1b being provided at by means of an O-ring 16b housed in an annular groove in the core mobile 16. On the upper surface of the end 16a of the core mobile 16 is made an indication arrow which cooperates with ON and OFF inscriptions on the upper wall 1a of the case, so visually indicate the electrical state of the circuit breaker (Figure 4b). When the power supply system 26 of the coil excitation 7 is faulty, it suffices that the user exercises manually a pressing force according to arrow 28 in the vertical downward direction on the upper end 16a of the movable core 16 to trigger the actuating means 5 of the transverse contact bridge 6.

    De même, la figure 5 montre une seconde option qui consiste à remplacer l'actionnement manuel (figure 4) par un actionnement pneumatique à air comprimé. Toujours en cas de défaillance du système électrique d'alimentation de la bobine d'excitation 7, un système pneumatique non représenté envoie de l'air comprimé selon la flèche 29 dans un compartiment supérieur 30 formé entre un prolongement tubulaire 1c de l'ouverture tubulaire 1b et de l'extrémité supérieure 16a du noyau mobile 16. L'effet provoqué est alors identique à un actionnement manuel selon la figure 4.Similarly, Figure 5 shows a second option which consists of replace manual actuation (figure 4) with actuation pneumatic compressed air. Always in case of failure of the electric supply system for excitation coil 7, one pneumatic system not shown sends compressed air according to the arrow 29 in an upper compartment 30 formed between a tubular extension 1c of tubular opening 1b and end upper 16a of the mobile core 16. The effect caused is then identical to manual actuation according to figure 4.
