Each mobile contact is actuated by using a synchronization and actuation device using the cam.

Description

DESCRIPTIONDESCRIPTION DOMAINE TECHNIQUETECHNICAL AREA

L'invention se rapporte au domaine de l'appareillage électrique équipant les dispositifs d'évacuation d'énergie des alternateurs dans les centrales de production d'énergie. L'invention concerne l'actionnement des différents éléments de coupure de sorte que les disjoncteurs d'alternateur soient de structure plus simple.The invention relates to the field of electrical equipment equipping the energy evacuation devices of generators in power generation plants. The invention relates to the actuation of the different breaking elements so that the alternator circuit breakers are of simpler structure.

Plus particulièrement, l'invention concerne un disjoncteur d'alternateur couplé à un sectionneur dans lequel les différents mouvements relatifs entre contacts se font au moyen d'une came cylindrique permettant d'optimiser la synchronisation et la vitesse de séparation entre les contacts, tout en conservant la compacité du disjoncteur.More particularly, the invention relates to an alternator circuit breaker coupled to a disconnector in which the different relative movements between contacts are made by means of a cylindrical cam to optimize the synchronization and the speed of separation between the contacts, while maintaining the compactness of the circuit breaker.

ÉTAT DE LA TECHNIQUE ANTÉRIEURESTATE OF THE PRIOR ART

En sortie de centrale, par exemple pour chaque alternateur, une option de sécurité est de disposer d'un disjoncteur permettant d'isoler le circuit concerné avant le transformateur relié à une ligne de transport d'énergie. Ce type d'appareillage, sous une tension de l'ordre de 15 kV à 36 kV, assure alors les fonctions de passage de fort courant permanent (de l'ordre de plusieurs milliers d'ampères) et de coupure de fort courant de défaut (de l'ordre de plusieurs dizaines de milliers d'ampères), tout en isolant le circuit.At the output of the plant, for example for each alternator, a safety option is to have a circuit breaker to isolate the circuit before the transformer connected to a power line. This type of switchgear, under a voltage of the order of 15 kV to 36 kV, then performs the functions of passing strong permanent current (of the order of several thousand amperes) and breaking high fault current. (of the order of tens of thousands of amperes), while isolating the circuit.

Au vu de l'intensité de courant présente à titre nominal dans le circuit, la coupure est effectuée en deux étapes grâce à deux interrupteurs en parallèle, l'un permettant le passage de courant nominal permanent et l'autre assurant la coupure du courant de court-circuit, définissant ainsi un « circuit principal » et un « circuit auxiliaire ».In view of the current intensity present as nominal in the circuit, the cut is performed in two stages by two switches in parallel, one permitting the passage of permanent nominal current and the other ensuring the breaking of the current of short circuit, thus defining a "main circuit" and an "auxiliary circuit".

Les contacts de l'interrupteur du circuit principal pour ces disjoncteurs d'alternateur sont suffisamment massifs pour supporter des courants nominaux élevés sans s'échauffer exagérément, et ils définissent un volume relativement important. L'interrupteur de coupure comprend classiquement une ampoule de dimensions réduites, disposée à l'intérieur de ce volume et comprenant des contacts d'arc mobiles l'un par rapport à l'autre, qui ne supportent de fait que le courant de coupure du disjoncteur.The main circuit switch contacts for these alternator circuit breakers are large enough to withstand high nominal currents without overheating, and they define a relatively large volume. The cut-off switch conventionally comprises a bulb of reduced dimensions, disposed inside this volume and comprising movable arcing contacts relative to each other, which in fact only support the breaking current of the breaker.

De façon usuelle, les contacts principaux s'écartent tout d'abord et parcourent une distance suffisante avant que le courant ne commute sur les contacts d'arc, qui s'ouvrent alors et provoquent l'interruption du courant.Usually, the main contacts first deviate and travel a sufficient distance before the current switches on the arcing contacts, which then open and cause the interruption of the current.

Il est habituel que le disjoncteur d'alternateur soit associé à un sectionneur, qui n'a aucun pouvoir de coupure : il s'ouvre uniquement lorsque le disjoncteur est ouvert et donc lorsque le courant ne transite plus dans le circuit. Il est connu que le sectionneur puisse être intégré au disjoncteur sectionneur de centrale décrit par exemple dans EP 0 877 405 .It is usual that the alternator circuit breaker is associated with a disconnector, which has no breaking capacity: it opens only when the circuit breaker is open and therefore when the current no longer passes through the circuit. It is known that the disconnector can be integrated in the circuit breaker central disconnector described for example in EP 0 877 405 .

L'actionnement des différents éléments de coupure d'un tel disjoncteur sectionneur doit être réalisé dans l'ordre précité, et en optimisant les vitesses de séparation. Or, au vu de la taille et du poids de l'ensemble, toutes les solutions ne peuvent être envisagées.The actuation of the various breaking elements of such a disconnecting circuit breaker must be performed in the aforementioned order, and optimizing the separation speeds. However, given the size and weight of all, all solutions can not be considered.

En particulier, selon l'état de la technique, l'actionnement se fait de façon usuelle ( EP 0 877 405 ) par l'intermédiaire de leviers munis de ressorts, qui posent cependant le problème du dimensionnement de ces derniers, et surtout de leur fatigue et leur détérioration à terme.In particular, according to the state of the art, the actuation is done in the usual way ( EP 0 877 405 ) by means of levers with springs, which however pose the problem of the dimensioning of the latter, and especially of their fatigue and their deterioration in the long run.

Une autre option concerne la réalisation de systèmes de guidage de bielles (document EP 0 878 817 ), qui sont cependant très difficiles à concevoir et d'encombrement important.Another option concerns the realization of rod guide systems (document EP 0 878 817 ), which are however very difficult to design and large size.

EXPOSÉ DE L'INVENTIONSTATEMENT OF THE INVENTION

L'invention a pour objet de rendre les disjoncteurs d'alternateurs plus compacts et simples à réaliser grâce à un nouveau système d'actionnement à commande unique.The object of the invention is to make the alternator circuit breakers more compact and simple to implement thanks to a new, single-controlled actuation system.

Plus particulièrement, l'invention concerne sous l'un de ses aspects un disjoncteur sectionneur d'alternateur comprenant un interrupteur de commutation en parallèle avec un interrupteur de coupure, par exemple une chambre à vide ; chacun des interrupteurs comprend une paire de contacts mobiles en translation l'un par rapport à l'autre selon un axe respectif, grâce à des moyens d'actionnement. Le disjoncteur comprend en outre un interrupteur de section, avantageusement en série avec l'interrupteur de coupure, qui comprend une paire de contacts mobiles l'un par rapport à l'autre, avantageusement en translation, grâce à des moyens d'actionnement.More particularly, the invention relates in one of its aspects to an alternator disconnect circuit breaker comprising a switching switch in parallel with a breaking switch, for example a vacuum chamber; each of the switches comprises a pair of movable contacts in translation relative to each other along a respective axis, thanks to actuating means. The circuit breaker further comprises a section switch, advantageously in series with the cutoff switch, which comprises a pair of movable contacts relative to each other, advantageously in translation, by means of actuating means.

De préférence, les trois axes de déplacement des contacts sont confondus. Usuellement, un seul contact de chaque paire est mobile, l'autre étant fixe.Preferably, the three axes of displacement of the contacts are merged. Usually, only one contact of each pair is mobile, the other is fixed.

Les moyens d'actionnement de l'un des interrupteurs, ou de plusieurs, peuvent être couplés au contact correspondant par l'intermédiaire d'une tige de connexion, afin de laisser une certaine distance entre les contacts.The actuating means of one or more of the switches can be coupled to the corresponding contact via a connecting rod, to allow a certain distance between the contacts.

Le disjoncteur comprend par ailleurs des moyens de synchronisation permettant, lors d'une coupure, de séparer successivement et dans cet ordre les contacts de l'interrupteur de commutation, puis de l'interrupteur de coupure, puis du sectionneur ; les moyens de synchronisation permettent également de refermer successivement les contacts dans l'ordre inverse. Une fermeture de l'interrupteur de coupure, en particulier s'il s'agit d'une ampoule à vide, en fin de manoeuvre d'ouverture peut être prévue. Avantageusement, les moyens de synchronisation sont couplés aux moyens d'actionnement et permettent, par une commande unique, la mise en oeuvre de chacune des interruptions.The circuit breaker furthermore comprises synchronization means making it possible, during a break, to separate successively and in this order the contacts of the switching switch, then of the breaking switch and then of the disconnector; the synchronization means also make it possible to successively close the contacts in the reverse order. Closing the cut-off switch, particularly if it is a vacuum interrupter, at the end of the opening maneuver can be provided. Advantageously, the synchronization means are coupled to the actuating means and allow, by a single command, the implementation of each of the interrupts.

Selon l'invention, à des fins de compacité du disjoncteur et de simplicité de la commande, les moyens d'actionnement et de synchronisation d'au moins les premier et deuxième interrupteurs comprennent une came cylindrique, c'est-à-dire un cylindre muni de lumières coopérant avec des éléments coulissants permettant l'actionnement des contacts. De préférence, le cylindre actionne également le sectionneur. Le cylindre est commandé en rotation par un système approprié, par exemple une chaîne de transmission ou un ensemble de bielles actionnées par levier.According to the invention, for purposes of compactness of the circuit breaker and simplicity of the control, the actuating and synchronizing means of at least the first and second switches comprise a cylindrical cam, that is to say a cylinder provided with lights cooperating with sliding elements for actuating the contacts. Preferably, the cylinder also actuates the disconnector. The cylinder is rotated by a suitable system, for example a transmission chain or a set of rods operated by lever.

Les lumières d'actionnement et synchronisation comprennent une partie hélicoïdale, dont le sens d'enroulement dépend de la direction de translation du contact concerné, et dont la pente dépend de la vitesse de séparation relative des contacts. Pour générer les latences entre l'ouverture des contacts des interrupteurs, les parties hélicoïdales des lumières sont décalées l'une par rapport à l'autre par la présence de parties de pente nulle (c'est-à-dire s'étendant autour du cylindre de façon orthogonale à l'axe) ou faible.The actuating and synchronizing lights comprise a helical part, whose winding direction depends on the direction of translation of the contact concerned, and whose slope depends on the relative separation speed of the contacts. To generate the latencies between the opening of the switch contacts, the helical portions of the lights are shifted relative to each other by the presence of portions of zero slope (i.e., extending around the cylinder orthogonal to the axis) or weak.

Il est avantageux que le contact mobile d'un interrupteur au moins, ou de préférence de tous les interrupteurs, soit actionné par l'intermédiaire de plusieurs éléments coulissants répartis autour de sa périphérie, par exemple deux éléments diamétralement opposés ; ces éléments coulissants peuvent être couplés au contact par l'intermédiaire de tiges dont une extrémité est fixée au contact et l'autre porte l'élément coulissant. Chaque élément coulissant coopère avec une lumière correspondante du cylindre, les lumières permettant l'actionnement d'un unique contact étant de profil similaire mais décalées sur la périphérie du cylindre. Si des tiges entre élément coulissant et contact sont présentes, il est préféré que la pluralité de tiges d'actionnement d'un même contact soit couplée entre elles par l'intermédiaire d'une pièce assurant leurs positions géométriques, par exemple une barre.It is advantageous for the movable contact of at least one switch, or preferably of all the switches, to be actuated via a plurality of sliding elements distributed around its periphery, for example two diametrically opposed elements; these sliding elements can be coupled to the contact via rods whose one end is fixed to the contact and the other door the sliding element. Each sliding element cooperates with a corresponding light of the cylinder, the lights allowing the actuation of a single contact being of similar profile but offset on the periphery of the cylinder. If rods between sliding element and contact are present, it is preferred that the plurality of actuating rods of the same contact is coupled together by means of a part ensuring their geometric positions, for example a bar.

Selon un mode de réalisation préféré, les moyens d'actionnement sont guidés en translation par la présence d'ergots coopérant avec des rainures rectilignes situées sur l'enveloppe du disjoncteur. En particulier, les éléments coulissants sont prolongés perpendiculairement à l'axe de déplacement par ces ergots.According to a preferred embodiment, the actuating means are guided in translation by the presence of lugs cooperating with rectilinear grooves located on the casing of the circuit breaker. In particular, the sliding elements are extended perpendicularly to the axis of movement by these lugs.

EXPOSÉ DÉTAILLÉ DE MODES DE RÉALISATION PARTICULIERSDETAILED PRESENTATION OF PARTICULAR EMBODIMENTS

Le principe de fonctionnement d'un disjoncteur, et en particulier d'un disjoncteur d'alternateur 1 selon l'invention, est schématisé en figure 1, avec un circuit principal dans lequel circule en fonctionnement une intensité I0 proche de l'intensité nominale I, et un circuit auxiliaire sollicité pour la coupure de court-circuit.The operating principle of a circuit breaker, and in particular of an alternator circuit breaker 1 according to the invention, is shown schematically in FIG. 1, with a main circuit in which an intensity I 0 close to the rated current flows in operation. I, and an auxiliary circuit solicited for the short circuit cutoff.

Pour un disjoncteur d'alternateur, le passage d'un courant I d'une intensité nominale supérieure à plusieurs milliers d'ampères nécessite l'utilisation sur le circuit principal d'un interrupteur 10 dont les contacts sont particulièrement conducteurs, par exemple en cuivre ; leur pouvoir de coupure est cependant limité en raison de la génération d'arcs électriques. Un deuxième interrupteur 20 de coupure est mis en parallèle avec le premier 10 afin d'effectuer la fonction de coupure proprement dite, l'ouverture du premier interrupteur 10 commutant de fait le courant I du circuit principal sur ce circuit auxiliaire ; les contacts de ce deuxième interrupteur 20, par exemple en tungstène, sont de performance limitée en ce qui concerne le passage du courant nominal I, mais possèdent un fort pouvoir de coupure.For an alternator circuit breaker, the passage of a current I with a rated current greater than several thousand amperes requires the use on the main circuit of a switch 10 whose contacts are particularly conductive, for example copper ; their breaking capacity is however limited because of the generation of electric arcs. A second switch 20 is connected in parallel with the first 10 in order to perform the actual cutoff function, the opening of the first switch 10 actually switching the current I of the main circuit on this auxiliary circuit; the contacts of this second switch 20, for example tungsten, are of limited performance with respect to the passage of the rated current I, but have a high breaking capacity.

Ainsi, les fonctions de transmission du courant permanent et de coupure de court-circuit sont séparées : en cas de sollicitation, le premier interrupteur 10 est tout d'abord activé, le courant I passe alors totalement dans le circuit auxiliaire et entraîne l'ouverture du deuxième interrupteur 20 pour obtenir la fonction de coupure. En outre, un troisième interrupteur 30 est ensuite ouvert : sa fonction est principalement une fonction de sécurité, son association sur le circuit auxiliaire permettant d'éviter une baisse de tenue diélectrique du deuxième interrupteur 20 qui pourrait accidentellement permettre le passage de courant dans la branche associée.Thus, the functions of transmission of the permanent current and short circuit break are separated: in case of bias, the first switch 10 is first activated, the current I then completely passes through the auxiliary circuit and causes the opening the second switch 20 to obtain the cutoff function. In addition, a third switch 30 is then open: its function is mainly a safety function, its association on the auxiliary circuit to avoid a drop dielectric strength of the second switch 20 which could accidentally allow the passage of current in the associated branch.

Pour refermer un tel disjoncteur, l'ordre est inversé : le sectionneur 30 est d'abord refermé, puis l'interrupteur de coupure 20, et enfin le premier interrupteur 10.To close such a circuit breaker, the order is inverted: the disconnector 30 is first closed, then the cut-off switch 20, and finally the first switch 10.

Chacun des interrupteurs 10, 20, 30 comprend une paire de contacts mobiles l'un par rapport à l'autre ; avantageusement, le premier contact 12, 22, 32 de chaque paire est fixe, et le deuxième contact 14, 24, 34 est mobile par rapport au premier.Each of the switches 10, 20, 30 comprises a pair of movable contacts with respect to each other; advantageously, the first contact 12, 22, 32 of each pair is fixed, and the second contact 14, 24, 34 is movable relative to the first.

En particulier, le premier interrupteur 10 peut être du type à gaz ; il peut aussi, notamment si le courant nominal est très élevé, s'agir lui-même d'un appareil de commutation comprenant deux interrupteurs mis en parallèle l'un par rapport à l'autre. De préférence cependant, tel qu'illustré en figures 2, le premier interrupteur 10 est un interrupteur dans l'air comprenant un premier contact 12 tubulaire fixe autour d'un axe AA dans lequel peut s'insérer un deuxième contact 14 tubulaire également.In particular, the first switch 10 may be of the gas type; it can also, especially if the nominal current is very high, itself be a switching device comprising two switches in parallel with each other. Preferably, however, as illustrated in FIG. 2, the first switch 10 is an air switch comprising a first fixed tubular contact 12 about an axis AA into which a second tubular contact 14 can also be inserted.

Le deuxième interrupteur 20 peut être un disjoncteur à gaz, du type SF6 ; de préférence, comme le courant I - I0 le traversant est faible en fonctionnement normal, il s'agit d'une ampoule à vide : ceci permet d'éviter l'utilisation de l'hexafluorure de soufre, ce qui augmente les performances écologiques et réduit les coûts.The second switch 20 may be a gas circuit breaker SF 6 type; preferably, since the current I - I 0 passing through it is weak in normal operation, it is a vacuum interrupter: this makes it possible to avoid the use of hexafluoride sulfur, which increases ecological performance and reduces costs.

Enfin, le troisième interrupteur 30 peut comprendre un contact fixe 32 dans lequel peut s'insérer un autre contact mobile 34 le long de l'axe AA d'ouverture/fermeture, du type tige.Finally, the third switch 30 may comprise a fixed contact 32 in which can be inserted another movable contact 34 along the axis AA of opening / closing, the rod type.

De préférence, les premier et deuxième interrupteurs 10, 20 sont coaxiaux : cette coaxialité des circuits électriques est favorable à la commutation du courant du circuit principal vers le circuit secondaire ; les contacts des deux interrupteurs s'étendent ainsi dans la même direction longitudinale et sont déplacés en translation parallèlement à cette direction AA. Dans le mode de réalisation préféré, les contacts du troisième interrupteur 30 se déplacent eux aussi en translation et les trois axes le long desquels se déplacent les contacts 14, 24, 34 sont confondus.Preferably, the first and second switches 10, 20 are coaxial: this coaxiality of the electrical circuits is favorable for switching the current of the main circuit to the secondary circuit; the contacts of the two switches thus extend in the same longitudinal direction and are displaced in translation parallel to this direction AA. In the preferred embodiment, the contacts of the third switch 30 also move in translation and the three axes along which move the contacts 14, 24, 34 are merged.

Le fonctionnement de pôle du disjoncteur sectionneur 1 est tel que la manoeuvre des contacts de chaque interrupteur 10, 20, 30 est assurée de préférence par une commande unique liée aux pôles par une cinématique de synchronisation permettant d'assurer la séquence de fonctionnement.The pole operation of the isolating circuit-breaker 1 is such that the operation of the contacts of each switch 10, 20, 30 is preferably provided by a single control linked to the poles by a synchronization kinematics to ensure the sequence of operation.

Selon l'invention, chaque contact mobile 14, 24, 34 est actionné par l'intermédiaire d'un dispositif d'actionnement et de synchronisation utilisant un système de came rotative localisée dans une enveloppe 5 du disjoncteur 1. Cette solution permet de déterminer le mouvement de chaque interrupteur 10, 20, 30 dans une construction coaxiale qui favorise la compacité ; de conception aisée et robuste au cours du temps, le système à came 40 est localisé dans le disjoncteur 1 existant, sans augmenter son encombrement.According to the invention, each movable contact 14, 24, 34 is actuated via an actuating and synchronizing device using a rotary cam system located in an envelope 5 of the circuit breaker 1. This solution makes it possible to determine the movement of each switch 10, 20, 30 in a coaxial construction that promotes compactness; of easy and robust design during the time, the cam system 40 is located in the existing circuit breaker 1, without increasing its size.

En particulier, les moyens d'actionnement et de synchronisation comprennent un cylindre 40, de préférence de révolution autour de l'axe de translation AA des contacts 14, 24, 34 du disjoncteur 1.In particular, the actuating and synchronizing means comprise a cylinder 40, preferably of revolution about the translation axis AA of the contacts 14, 24, 34 of the circuit breaker 1.

Sur la paroi du cylindre 40 sont usinées des lumières 42, à raison d'au moins une lumière par contact à actionner : une première lumière 421 commande le mouvement d'ouverture et/ou de fermeture du premier interrupteur principal 10, une deuxième lumière 422 commande l'ouverture et/ou la fermeture du deuxième interrupteur secondaire 20, et une troisième lumière 423 sert à actionner l'interrupteur de section 30. Le dessin des lumières 42 permet la synchronisation des mouvements, ainsi que la détermination des vitesses de translation relatives.On the wall of the cylinder 40 are machined lights 42, at least one light by contact to operate: a first light 42 1 controls the opening and / or closing movement of the first main switch 10, a second light 42 2 controls the opening and / or closing of the second secondary switch 20, and a third light 42 3 serves to actuate the section switch 30. The drawing of the lights 42 allows the synchronization of the movements, as well as the determination of the speeds relative translation.

L'actionnement de chacun des interrupteurs est effectué par l'intermédiaire d'un élément 44 apte à coulisser dans la lumière 42 correspondante du cylindre 40 et solidarisé de façon fixe au contact. Si le contact est éloigné du cylindre 40, l'élément coulissant 44 peut être couplé à une extrémité d'une tige de connexion 46 qui est solidarisée, par son autre extrémité, de façon fixe au contact ; pour permettre une meilleure lisibilité, c'est ce dernier mode de réalisation qui est illustré en figure 3A, mais il faut comprendre que, dans la majorité des cas et à des fins de compacité, la tige de connexion 46 est absente et les éléments coulissants 44 sont partie intégrante du contact à déplacer.The actuation of each of the switches is effected by means of an element 44 able to slide in the corresponding slot 42 of the cylinder 40 and fixedly secured to the contact. If the contact is remote from the cylinder 40, the sliding element 44 can be coupled to one end of a connecting rod 46 which is secured, by its other end, fixedly in contact; to allow a better readability, it is this last embodiment which is illustrated in Figure 3A, but it should be understood that in most cases and for reasons of compactness, the connecting rod 46 is absent and the sliding elements 44 are part of the contact to move.

Ainsi, lors de la rotation du cylindre 40 (flèche R), selon le dessin de la lumière 42, l'élément coulissant 44 se déplace dans la lumière 42 et le contact, par exemple par l'intermédiaire de la tige 46, est animé en translation (flèche T).Thus, during the rotation of the cylinder 40 (arrow R), according to the design of the light 42, the sliding element 44 moves in the light 42 and the contact, for example via the rod 46, is animated in translation (arrow T).

De préférence, le contact, les éléments coulissants 44 et/ou les tiges de connexion 46 sont localisées à l'intérieur du cylindre 40 rotatif d'actionnement et synchronisation : le profil des lumières 42 peut ainsi être plus précis au vu du diamètre supérieur du cylindre 40, qui est également plus robuste.Preferably, the contact, the sliding elements 44 and / or the connecting rods 46 are located inside the rotary actuating and synchronizing cylinder 40: the profile of the slots 42 can thus be more accurate in view of the greater diameter of the 40 cylinder, which is also more robust.

Afin d'éviter tout effort de torsion sur le contact, et notamment toute rotation parasite d'une tige 46, de préférence, l'élément coulissant 44 lui-même est guidé en translation, ou la tige de connexion 46 est guidée longitudinalement. Avantageusement, le guidage est effectué par coopération entre un ergot 48 solidaire de l'élément coulissant 44 et/ou de la tige 46 et une rainure 50 parallèle à l'axe de translation AA du contact, par exemple localisée sur l'enveloppe 5 du disjoncteur 1. En particulier, l'élément coulissant 44 dans la lumière 42 du cylindre 40 peut être prolongé vers l'extérieur par un ergot 48 coulissant dans une rainure 50 de l'enveloppe 5.In order to avoid any twisting force on the contact, and especially any parasitic rotation of a rod 46, preferably, the sliding element 44 itself is guided in translation, or the connecting rod 46 is guided longitudinally. Advantageously, the guiding is carried out by cooperation between a lug 48 secured to the sliding element 44 and / or the rod 46 and a groove 50 parallel to the axis of translation AA of the contact, for example located on the casing 5 of the In particular, the sliding element 44 in the lumen 42 of the cylinder 40 can be extended outwards by a lug 48 sliding in a groove 50 of the casing 5.

Les lumières d'actionnement et de synchronisation sont dessinées de façon à maîtriser les caractéristiques de vitesse et de synchronisation entre le mouvement de chacun des interrupteurs 10, 20, 30.The actuating and synchronizing lights are designed to control the speed and timing characteristics between the movement of each of the switches 10, 20, 30.

Ainsi par exemple, dans un exemple illustré préféré, le cylindre 40 est localisé entre les premier et deuxième contacts 14, 24 qui se déplacent en sens opposés, le sectionneur 30 étant animé d'un mouvement similaire au premier interrupteur 10. Un dessin de lumières 42 est illustré en figure 3B, dans une version déroulée du cylindre 40.For example, in a preferred illustrated example, the cylinder 40 is located between the first and second contacts 14, 24 which move in opposite directions, the disconnector 30 being driven in a similar motion to the first switch 10. A drawing of lights 42 is illustrated in FIG. 3B, in an uncoiled version of the cylinder 40.

La première lumière 421 du cylindre 40 comprend une partie d'extrémité initiale 421i qui est hélicoïdale dans un premier sens : dès l'actionnement R du cylindre 40, le premier contact 14 du premier interrupteur 10 est sollicité en translation pour une séparation afin de couper le plus rapidement possible le courant. La pente de la première lumière 421 dépend de la vitesse relative T à obtenir en fonction de la vitesse de rotation R imprimée au cylindre 40 par ses moyens de commande 52.The first light 42 1 of the cylinder 40 comprises an initial end portion 42 1i which is helical in a first direction: upon actuation R of the cylinder 40, the first contact 14 of the first switch 10 is biased in translation for separation in order to to cut off the current as quickly as possible. The slope of the first light 42 1 depends on the relative speed T to be obtained as a function of the speed of rotation R printed on the cylinder 40 by its control means 52.

Une fois les contacts du premier interrupteur 10 ouverts, il n'est plus nécessaire de les actionner, et avantageusement, la première lumière 421 comprend une partie d'extrémité finale 421f qui est rectiligne, normale à l'axe AA. Il est possible également de prévoir une translation plus lente par un changement de pente, ou une inversion de mouvement...Once the contacts of the first switch 10 open, it is no longer necessary to actuate them, and advantageously, the first light 42 1 comprises a final end portion 42 1f which is rectilinear, normal to the axis AA. It is also possible to provide a slower translation by a change of slope, or a reversal of movement ...

La deuxième lumière 422 comprend quant à elle une partie d'extrémité initiale 422i qui n'est pas pentue mais linéaire selon un périmètre de la paroi : pendant un premier temps après l'actionnement, le deuxième interrupteur 20 n'est pas sollicité ; au contraire, il reste fermé de sorte que le courant passe du circuit principal au circuit auxiliaire. Grâce au dessin de la partie d'extrémité initiale 422i de la deuxième lumière, la rotation du cylindre 40 n'entraîne dans un premier temps aucune translation de l'élément coulissant 44 et donc du deuxième contact 24.The second light 42 2 comprises an initial end portion 42 2i that is not sloping but linear along a perimeter of the wall: for a first time after the actuation, the second switch 20 is not requested. ; on the contrary, it remains closed so that the current flows from the main circuit to the auxiliary circuit. Thanks to drawing of the initial end portion 42 2i of the second light, the rotation of the cylinder 40 does not initially cause any translation of the sliding element 44 and thus the second contact 24.

Une fois les contacts du premier interrupteur 10 séparés, il importe d'ouvrir l'interrupteur secondaire 20 : après la partie d'extrémité initiale 422i, la deuxième lumière 422 se prolonge par une partie médiane hélicoïdale 422m, dont la pente dépend de la vitesse relative d'ouverture de l'interrupteur 20. Dans le cadre représenté, le sens d'enroulement de la deuxième lumière 422m est inverse de celui de la partie d'extrémité initiale 421i de la première lumière, les deux contacts 14, 24 se déplaçant en sens opposé ; ceci n'est qu'illustratif. La longueur de la partie d'extrémité initiale de la deuxième lumière 422i dépend de la durée de latence avant l'actionnement du deuxième interrupteur 20 ; de préférence, l'arc couvert par la deuxième partie d'extrémité initiale 422i est inférieur à celui couvert par la première partie d'extrémité initiale 421i, une ouverture suffisante de l'interrupteur principal 10 étant juste définie pour permettre l'ouverture de l'ampoule à vide 20 sans risque d'amorcer. Par ailleurs, au vu des dimensions dans le cas d'une ampoule à vide 20, on note que la longueur de la partie médiane 422m de la lumière est très faible, la distance de séparation des contacts 22, 24 étant restreinte.Once the contacts of the first switch 10 are separated, it is important to open the secondary switch 20: after the initial end portion 42 2i , the second light 42 2 is extended by a helical median portion 42 2m , whose slope depends the relative speed of opening of the switch 20. In the illustrated frame, the winding direction of the second light 42 2m is opposite that of the initial end portion 42 1i of the first light, the two contacts 14, 24 moving in the opposite direction; this is only illustrative. The length of the initial end portion of the second lumen 42 2i depends on the latency time before the actuation of the second switch 20; preferably, the arc covered by the second initial end portion 42 2i is smaller than that covered by the first initial end portion 42 1i , a sufficient opening of the main switch 10 being just defined to allow the opening of the vacuum ampoule 20 without risk of priming. Moreover, in view of the dimensions in the case of a vacuum bulb 20, it is noted that the length of the middle portion 42 2m of the light is very small, the separation distance of the contacts 22, 24 being restricted.

De la même façon, l'actionnement du troisième contact 34 est décalé par rapport au déplacement du deuxième contact 24 : la troisième lumière 423 comprend une partie d'extrémité initiale linéaire 423i plus longue que la partie d'extrémité initiale 422i de la deuxième lumière et de la partie médiane 422m de cette deuxième lumière, de fait déterminée pour être supérieure à la distance correspondant au temps d'arc maximal ; il est possible naturellement d'imprimer à la place un mouvement de translation « lente ». Un enroulement hélicoïdal de la troisième lumière 423f est ensuite prévu, dans le sens d'enroulement de la première lumière 422i pour ce mode de réalisation où sectionneur 30 et premier interrupteur 10 fonctionnent « dans le même sens » même si l'inverse serait possible. Ici encore, il est avantageux que la partie d'extrémité finale 422f de la deuxième lumière soit linéaire et que les contacts 22, 24 ne bougent plus (au moins pendant un certain temps) une fois l'ouverture atteinte.In the same way, the actuation of the third contact 34 is shifted relative to the displacement of the second contact 24: the third light 42 3 comprises a linear initial end portion 42 3i longer than the initial end portion 42 2i of the second light and the middle portion 42 2m of this second light, determined to be greater than the corresponding distance at maximum arc time; it is possible, of course, to print a "slow" translation movement instead. A helical winding of the third light 42 3f is then provided, in the winding direction of the first light 42 2i for this embodiment where the disconnector 30 and the first switch 10 operate "in the same direction" even if the opposite would be the case. possible. Again, it is advantageous that the end end portion 42f of the second lumen is linear and that the contacts 22, 24 do not move (at least for a while) once the opening is reached.

Par le choix de la pente de chacun des enroulements 421i, 422m, 423f, il est possible d' ajuster la vitesse de séparation des contacts sans modifier la vitesse de rotation du cylindre 40 : les moyens de commande peuvent donc être simplifiés, et l'animation en rotation de la came cylindrique 40 peut être effectuée par tout système 52 adapté, par exemple par des bielles isolantes montées sur un levier, ou par un système de chaînes d'entraînement.By the choice of the slope of each winding 42 1i , 42 2m , 42 3f , it is possible to adjust the speed of separation of the contacts without changing the speed of rotation of the cylinder 40: the control means can be simplified, and the rotational animation of the cylindrical cam 40 can be performed by any system 52 adapted, for example by insulating rods mounted on a lever, or by a system of drive chains.

Grâce au choix des profils de lumière 42, on note en outre que la séquence de fermeture est également respectée.By choosing the light profiles 42, it is further noted that the closing sequence is also respected.

Il est possible d'adapter les dessins aux séquences souhaitées, et par exemple de prévoir des ouvertures en deux temps, ou de concevoir plus de deux ou trois parties pour chacune des lumières 421, 422, 423. En particulier, et tel que représenté sur la figure 3B, il est possible, afin de la protéger, de refermer l'ampoule à vide 20 une fois la section effectuée. A cette fin, la partie d'extrémité dite finale 422f de la deuxième lumière est de fait prolongée par une seconde partie médiane 422m', de sens opposé à la partie médiane 422m, qui permet de refermer les contacts 22, 24 de l'ampoule ; une seconde partie linéaire finale 422f, peut également être prévue.It is possible to adapt the drawings to the desired sequences, and for example to provide openings in two steps, or to design more than two or three parts for each of the lights 42 1 , 42 2 , 42 3 . In particular, and as shown in FIG. 3B, it is possible, in order to protect it, to close the vacuum interrupter 20 once the section has been completed. For this purpose, the so-called final end portion 42 2f of the second lumen is in fact extended by a second median portion 42 2m ' , in a direction opposite to the middle portion 42 2m , which makes it possible to close the contacts 22, 24 of the bulb; a second final linear part 42 2f can also be provided.

De plus, la commande et la synchronisation par came peuvent être choisies pour actionner les deux premiers interrupteurs 10, 20 seulement, si par exemple un sectionneur 30 « à couteau » est choisi.In addition, cam control and synchronization may be selected to operate the first two switches 10, only if, for example, a "knife" disconnector 30 is selected.

Selon un mode de réalisation avantageux (illustré dans une configuration particulière en figure 3A), pour équilibrer les efforts sur un contact, deux éléments coulissants 44, 44' y sont solidarisés de façon diamétralement opposée, et coulissent dans une lumière correspondante du cylindre 40 : le cylindre possède alors une paire de premières, respectivement deuxièmes et/ou troisièmes, lumières 42, 42', chaque lumière de la paire étant identique et décalée de 180° avec l'autre. Dans ce cas, de préférence, chaque élément coulissant 44, 44' comporte un ergot 48, 48' de guidage dans une rainure 50, 50' opposée de l'enveloppe 5 du disjoncteur 1.According to an advantageous embodiment (illustrated in a particular configuration in FIG. 3A), in order to balance the forces on a contact, two sliding elements 44, 44 'are connected therein diametrically opposite one another, and slide in a corresponding slot of the cylinder 40: the cylinder then has a pair of first, respectively second and / or third, lights 42, 42 ', each light of the pair being identical and shifted 180 ° with the other. In this case, preferably, each sliding element 44, 44 'has a lug 48, 48' for guiding in an opposite groove 50, 50 'of the casing 5 of the circuit breaker 1.

En particulier si le contact est éloigné du cylindre d'actionnement 40, chaque élément coulissant 44, 44' peut être connecté au contact par l'intermédiaire d'une tige 46, 46'. Avantageusement, les extrémités des tiges 46, 46' qui comprennent les éléments de coulissement 44, 44' sont reliées entre elles, à l'intérieur du cylindre 40, par une barre 54 orthogonale assurant leur écartement et leur maintien en position afin de limiter les efforts.In particular if the contact is remote from the actuating cylinder 40, each sliding element 44, 44 'can be connected to the contact by via a rod 46, 46 '. Advantageously, the ends of the rods 46, 46 'which comprise the sliding elements 44, 44' are connected together, inside the cylinder 40, by an orthogonal bar 54 ensuring their spacing and their holding in position in order to limit the efforts.

Il est entendu que le mode de réalisation avec deux éléments coulissants 44, 44' est donné à titre d'exemple et qu'on peut par exemple concevoir plusieurs éléments, répartis de façon régulière ou non, sur la périphérie du contact.It is understood that the embodiment with two sliding elements 44, 44 'is given by way of example and that one can for example design several elements, evenly distributed or not, on the periphery of the contact.

Chacun des interrupteurs de préférence, ou seulement certains d'entre eux, peuvent comprendre deux éléments coulissants. Selon un mode de réalisation avantageux, seul un des interrupteurs, par exemple l'ampoule à vide, est actionné par l'intermédiaire de tiges d'actionnement, reliées ou non entre elles par des barres.Each of the switches preferably, or only some of them, may comprise two sliding elements. According to an advantageous embodiment, only one of the switches, for example the vacuum interrupter, is actuated by means of actuating rods, connected or not to each other by bars.

Grâce à l'actionnement selon l'invention, il est possible de contrôler les différents mouvements d'ouverture/fermeture des interrupteurs 10, 20, 30 de manière indépendante les uns des autres. De plus, à l'inverse du ressort, ce contrôle n'est pas altéré au cours du temps. L'actionnement par came 40 permet en outre de conserver une compacité au pôle de disjoncteur 1, le cylindre 40 prenant place au sein du disjoncteur usuel 1. La coaxialité des circuits peut donc être maintenue, même s'il est possible, en particulier en réalisant une tige d'actionnement 46 externe au cylindre 40, d'utiliser un disjoncteur sectionneur d'axes sécants tel que présenté dans la demande EP 0 878 817 .Thanks to the actuation according to the invention, it is possible to control the different opening / closing movements of the switches 10, 20, 30 independently of each other. Moreover, unlike the spring, this control is not altered over time. The cam actuation 40 furthermore makes it possible to maintain compactness at the circuit-breaker pole 1, the cylinder 40 taking place within the usual circuit-breaker 1. The coaxiality of the circuits can therefore be maintained, even if it is possible, in particular in realizing an actuating rod 46 external to the cylinder 40, using a circuit breaker of intersecting axes as presented in the application EP 0 878 817 .
