Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention est relative à un bloc unitaire de commutation comprenant des moyens électriques de commutation comprenant :

  • deux contacts fixes respectivement reliés à une plage électrique de raccordement dudit bloc unitaire ;
  • un contact mobile comportant un pont ayant un corps allongé suivant un axe longitudinal et ayant deux extrémités pouvant chacune collaborer avec un contact fixe dans une position de fermeture des contacts dudit bloc ;
The invention relates to a unitary switching unit comprising electrical switching means comprising:
  • two fixed contacts respectively connected to an electrical connection range of said unit block;
  • a movable contact having a bridge having a body elongate along a longitudinal axis and having two ends each capable of collaborating with a fixed contact in a closed position of the contacts of said block;

Le bloc unitaire de commutation comporte en outre un dispositif d'actionnement du contact mobile comportant un porte contact mobile.The unit switching unit further comprises a device for actuating the movable contact comprising a movable contact carrier.

L'invention est aussi relative à un dispositif de commutation électrique comportant au moins un bloc unitaire de commutation de courant.The invention also relates to an electrical switching device comprising at least one unitary block of current switching.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Les contacteurs sont généralement dimensionnés pour réaliser un grand nombre de manoeuvres d'établissement et d'interruption du courant dans une charge. Cependant certains d'entre eux ne sont pas utilisés pour ce type d'application, mais plutôt comme passeur de courant avec un faible nombre de manoeuvres d'établissement et d'interruption du courant. C'est le cas par exemple de contacteurs utilisés en association avec un variateur de vitesse comme élément de court-circuitage du variateur ou aussi pour assurer un isolement galvanique.The contactors are generally sized to perform a large number of operations of establishment and interruption of the current in a load. However some of them are not used for this type of application, but rather as a current feeder with a low number of operations of establishment and interruption of the current. This is the case for example of contactors used in combination with a variable speed drive as a short-circuiting element of the drive or also to ensure galvanic isolation.

Dans ce cas le dimensionnement du contacteur n'est aujourd'hui pas optimisé pour le besoin. En effet, un contacteur utilisé pour ce type d'application est généralement surdimensionné au niveau de ses pastilles de contact électrique dont le volume est prévu pour réaliser un grand nombre de manoeuvres. Ce surdimensionnement peut entrainer des couts supplémentaires de l'installation. En outre, la « ligne de passage courant » du contacteur n'est pas non plus optimisée pour garantir un passage d'un courant permanent maximum dans un volume minimum. On entend par « ligne de passage courant », l'ensemble formé par les contacts fixes associés au contact mobile.In this case, the sizing of the contactor is not optimized for the moment. Indeed, a contactor used for this type of application is generally oversized at its electrical contact pads whose volume is expected to perform a large number of maneuvers. This oversizing can lead to additional costs of the installation. In addition, the "current line of passage" of the contactor is also not optimized to ensure a passage of a maximum permanent current in a minimum volume. The term "current passage line" means the assembly formed by the fixed contacts associated with the moving contact.

Avantageusement, le bloc unitaire de commutation comporte deux premières branches de passage courant entrainées de manière à passer simultanément de leur position d'ouverture à leur position de fermeture et inversement, lesdites premières branches étant disposées de manière parallèle l'une par rapport à l'autre.Advantageously, the unitary switching unit comprises two first current passage branches driven so as to simultaneously move from their open position to their closed position and vice versa, said first branches being arranged parallel to one another with respect to the other.

De préférence, chaque première branche est montée en translation sur le porte contact mobile entre deux positions dites de pression de contact, un premier ressort de pression de contact appliquant une première force de pression de contact sur chaque première branche.Preferably, each first branch is mounted in translation on the movable contact holder between two so-called contact pressure positions, a first contact pressure spring applying a first contact pressure force on each first branch.

Preferably, the housing is formed of two half-shells 80A assembled to form an assembly of substantially parallelepipedal shape developing along a longitudinal plane XZ.

Dans le cas d'un contacteur, un électro-aimant (non représenté) agit sur le mécanisme d'actionnement 34 pour commander la fermeture et l'ouverture des contacts électriques.In the case of a contactor, an electromagnet (not shown) acts on the actuating mechanism 34 to control the closing and opening of the electrical contacts.

Selon un mode préférentiel de réalisation de l'invention tel que représenté sur les figures 1, 2 et 3A, le bloc unitaire de commutation 80 comprend des moyens électriques de commutation comprenant deux contacts fixes 320 comportant respectivement des zones de contact électrique 37, 39. Les moyens de commutation comportent en outre un contact mobile 330 comportant un pont ayant un corps allongé suivant un axe longitudinal X et deux extrémités comportant respectivement des zones de contact 36, 40 pouvant collaborer avec les zones de contact 37, 39 d'un contact fixe 320 dans une position de fermeture des contacts 320, 330 dudit bloc. Dans cette position de fermeture, des moyens élastiques 41, 42, tels que notamment des ressorts hélicoïdaux, permettent d'assurer entre les zones de contact 36, 40 et 37, 39 une pression de contact suffisante pour garantir le passage du courant dans de bonnes conditions.According to a preferred embodiment of the invention as represented on the Figures 1, 2 and 3A the switching unit block 80 comprises electrical switching means comprising two fixed contacts 320 respectively comprising electrical contact zones 37, 39. switching further comprise a movable contact 330 comprising a bridge having an elongate body along a longitudinal axis X and two ends respectively comprising contact zones 36, 40 which can collaborate with the contact zones 37, 39 of a fixed contact 320 in a closing position of the contacts 320, 330 of said block. In this closed position, resilient means 41, 42, such as in particular helical springs, ensure between the contact zones 36, 40 and 37, 39 a contact pressure sufficient to ensure the passage of the current in good conditions.

Des plages de raccordement 45 relient respectivement lesdits contacts fixes 320 à une borne électrique (non représentée).Connection pads 45 respectively connect said fixed contacts 320 to an electrical terminal (not shown).

Le pont mobile de contact 330, peut se déplacer en translation sous l'action du dispositif d'actionnement 34. En effet, le mécanisme d'actionnement 34 commande l'ouverture des contacts électriques en déplaçant en translation le pont mobile de contact 330 selon une direction perpendiculaire à l'axe longitudinal X. Le pont mobile de contact 330 se déplace entre une position d'ouverture et une position de fermeture des contacts électriques. Le dispositif d'actionnement 34 du contact mobile 330 comportant un porte contact mobile 38.The movable contact bridge 330 can move in translation under the action of the actuating device 34. Indeed, the actuating mechanism 34 controls the opening of the electrical contacts by moving in translation the movable contact bridge 330 according to a direction perpendicular to the longitudinal axis X. The movable contact bridge 330 moves between an open position and a closed position of the electrical contacts. The actuating device 34 of the movable contact 330 comprising a movable contact holder 38.

On définit ainsi deux volumes d'ouverture 35 correspondant à l'espace dans lequel sont disposées les zones de contact 37, 39 d'un contact fixe 320 et les zone de contact 36, 40 associées du contact mobile 330.Two opening volumes 35 corresponding to the space in which the contact zones 37, 39 of a fixed contact 320 and the contact zones 36, 40 associated with the movable contact 330 are thus defined are defined.

Selon un mode particulier de réalisation de l'invention, chaque volume d'ouverture 35 peut être associé à une chambre d'extinction d'arc 24. Chaque chambre d'extinction d'arc 24 s'ouvrant sur le volume d'ouverture 35, est délimitée par deux flasques latéraux parallèles et placés de part et d'autre d'un plan longitudinal médian XZ. Les deux flasques latéraux sont disposés de manière à encadrer une partie du pont mobile 330 sur tout son déplacement entre la position d'ouverture et la position de fermeture. Autrement dit, les deux flasques latéraux sont espacés l'un de l'autre pour autoriser le déplacement du pont mobile de contact 330. Les flasques latéraux parallèles d'une chambre d'extinction d'arc 24 peuvent comporter des surfaces intérieures recouvertes d'un matériau gazogène.According to a particular embodiment of the invention, each opening volume 35 may be associated with an arc extinction chamber 24. Each arc extinction chamber 24 opening on the opening volume 35 , is delimited by two parallel lateral flanges and placed on either side of a median longitudinal plane XZ. The two side flanges are arranged to frame a portion of the movable bridge 330 over its entire displacement between the open position and the closed position. In other words, the two lateral flanges are spaced from each other to allow the displacement of the movable contact bridge 330. The parallel side flanges of an arc extinguishing chamber 24 may comprise interior surfaces covered with a gas generating material.

Selon un mode préférentiel de réalisation de l'invention tel que représenté sur les figures 6 et 7, le contact mobile 330 comporte au moins une première branche 331 dite de passage du courant et une seconde branche 332 dite de commutation du courant électrique. Les première et seconde branches 331, 332 sont destinées à relier respectivement les deux contacts fixes 320 dans la position de fermeture des contacts 330, 320. Ladite au moins une première branche 331 de passage comprend deux extrémités comportant respectivement une zone de contact 40 pouvant collaborer avec une zone de contact 39 d'un contact fixe 320. En outre, la seconde branche de commutation 332 comprend deux extrémités comportant respectivement une zone de contact 36 pouvant collaborer avec une zone de contact 37 d'un contact fixe 320.According to a preferred embodiment of the invention as represented on the Figures 6 and 7 , the movable contact 330 comprises at least one first branch 331 said passage of the current and a second branch 332 said switching of the electric current. The first and second branches 331, 332 are intended to connect respectively the two fixed contacts 320 in the closed position of the contacts 330, 320. Said at least one first passage branch 331 comprises two ends respectively comprising a contact zone 40 that can collaborate with a contact zone 39 of a fixed contact 320. In addition, the second switching branch 332 comprises two ends respectively comprising a contact zone 36 which can collaborate with a contact zone 37 of a fixed contact 320.

Selon mode particulier de développement de l'invention, le contact mobile 330 comporte de préférence deux premières branches 331 de passage entrainées de manière à passer simultanément de leur position d'ouverture à leur position de fermeture et inversement. Comme représenté sur les figures 3B et 5A, lesdites premières branches 331 sont disposées de manière parallèle l'une par rapport à l'autre. Cette mise en parallèle de deux premières branches 331 (au lieu d'une seule première branche) permet de faire passer un courant plus élevé dans un volume donné.According to the particular embodiment of the invention, the movable contact 330 preferably comprises two first passage branches 331 driven so as to simultaneously move from their open position to their closed position and vice versa. As shown on Figures 3B and 5A said first legs 331 are arranged parallel to one another. This paralleling two first branches 331 (instead of a single first branch) allows to pass a higher current in a given volume.

Les première et seconde branches 331, 332 sont mobiles l'une par rapport à l'autre. En outre les première et seconde branches 331, 332 sont solidaires du porte contact 38.The first and second branches 331, 332 are movable relative to each other. In addition, the first and second branches 331, 332 are integral with the contact holder 38.

Ainsi, à titre d'exemple de réalisation, le fait d'utiliser dans un volume donné deux premières branches 331 de passage et une seconde branche 332 de commutation en parallèle permet d'obtenir un gain de 40% sur le courant admissible. Ce gain est estimé en comparaison avec un contacteur connu utilisant un pont mobile ayant une seule branche mobile.Thus, as an exemplary embodiment, the fact of using in a given volume two first branches 331 of passage and a second branch 332 of parallel switching provides a gain of 40% on the permissible current. This gain is estimated in comparison with a known contactor using a movable bridge having a single movable branch.

Le but de l'invention est d'éviter que les zones de contact 40 des premières branches 331 ne soient en contact avec un arc de commutation au moment de la fermeture et/ou de l'ouverture des contacts électriques 320, 330.The object of the invention is to prevent the contact zones 40 of the first branches 331 from being in contact with a switching arc at the moment of closing and / or opening of the electrical contacts 320, 330.

Le fait que les première et seconde branches 331, 332 soient mobiles l'une par rapport à l'autre autorise le fait que les premières branches 331 de passage soient éloignées des deux contacts fixes 320 alors que la seconde branche 332 de commutation est encore en contact avec lesdits contacts fixes 320 au moment de l'ouverture des contacts 330, 320 dudit bloc. Par ailleurs, le fait que les deux branches 331, 332 soient mobiles l'une par rapport à l'autre autorise le fait que la seconde branche 332 soit en contact avec les deux contacts fixes 320 alors que les premières branche 331 sont encore éloignées des contacts fixes 320 au moment de la fermeture des contacts 330, 320 dudit bloc.The fact that the first and second branches 331, 332 are movable relative to each other allows the first branches 331 passage are removed from the two fixed contacts 320 while the second branch 332 switching is still in effect. contact with said fixed contacts 320 at the time of opening of the contacts 330, 320 of said block. Furthermore, the fact that the two branches 331, 332 are movable relative to each other allows the second branch 332 to be in contact with the two fixed contacts 320 while the first branch 331 are still distant from the fixed contacts 320 at the time of closure of the contacts 330, 320 of said block.

Autrement dit, les premières branches mobiles 331 de passage et les secondes branches 332 de commutation, grâce à l'action du porte contact mobile 38, se déplacent de manière décalée dans la séquence de fermeture du contacteur de manière à fermer en premier la seconde branche 332 de commutation. Lesdites première et seconde branches 331, 332 se déplacent de manière décalée dans la séquence d'ouverture du contacteur de manière à ouvrir en dernier la seconde branche 332 de commutation. Ainsi, les zones de contact 40 de la première branche 331 de passage ne voient jamais d'arc électrique.In other words, the first movable branches 331 for passage and the second branches 332 for switching, thanks to the action of the movable contact holder 38, move in an offset manner in the closing sequence of the contactor so as to close first the second branch 332 switching. Said first and second branches 331, 332 move in an offset manner in the opening sequence of the contactor so as to open lastly the second switching branch 332. Thus, the contact zones 40 of the first passage branch 331 never see an electric arc.

Comme représenté sur la figure 3B, le décalage temporel dans le mouvement des première et seconde branches 331, 332 est réalisé grâce au positionnement relatif desdites branches mobiles dans le porte contact mobile 38. Lorsque les contacts électriques 330, 320 sont fermés, un premier jeu de fonctionnement J1 sépare les premières branches de passage 331 du porte contact mobile 38 et un second jeu de fonctionnement J2 sépare la seconde branche de commutation 332 du porte contact mobile 38. Le dimensionnement relatif des premiers et seconds jeux J1, J2 permet d'obtenir le décalage temporel dans le mouvement des branches pendant l'ouverture et la fermeture des contacts électriques 320, 330.Ainsi selon ce mode de réalisation de l'invention, le premier jeu de fonctionnement J1 est inférieur au second jeu de fonctionnement J2 pour que les premières branches de passage 331 s'ouvrent en premier et se ferment en dernier.As shown on the figure 3B , the time shift in the movement of the first and second legs 331, 332 is achieved by the relative positioning of said movable legs in the movable contact holder 38. When the electrical contacts 330, 320 are closed, a first operating clearance J1 separates the first passage branches 331 of the movable contact holder 38 and a second operating set J2 separates the second switching branch 332 from the movable contact holder 38. The relative dimensioning of the first and second sets J1, J2 makes it possible to obtain the time shift in the movement during the opening and closing of the electrical contacts 320, 330. Thus, according to this embodiment of the invention, the first operating clearance J1 is smaller than the second operating clearance J2 so that the first passageways 331 s open first and close last.

Selon un mode préférentiel développement de l'invention tel que représenté sur la figure 3B, la première branche 331 est montée en translation sur le porte contact mobile 38 entre deux positions dites de pression de contact. Un premier ressort de pression de contact 41 applique une première force de pression de contact F1. Selon cet exemple de réalisation, chaque première branche 331 est montée en translation sur le porte contact mobile 38 entre deux positions dites de pression de contact. Un premier ressort de pression de contact 41 applique une première force de pression de contact F1 sur chaque première branche 331.According to a preferred embodiment of the invention as shown in the figure 3B the first branch 331 is mounted in translation on the movable contact holder 38 between two so-called contact pressure positions. A first contact pressure spring 41 applies a first contact pressure force F1. According to this exemplary embodiment, each first branch 331 is mounted in translation on the movable contact holder 38 between two so-called contact pressure positions. A first contact pressure spring 41 applies a first contact pressure force F1 to each first branch 331.

Selon ce mode préférentiel développement de l'invention la seconde branche 332 est montée en translation sur le porte contact mobile 38 entre deux positions dites de pression de contact, un second ressort de pression de contact 42 appliquant une seconde force de pression de contact F2.According to this preferred embodiment of the invention the second branch 332 is mounted in translation on the movable contact holder 38 between two so-called contact pressure positions, a second contact pressure spring 42 applying a second contact pressure force F2.

Selon ce mode préférentiel de réalisation de l'invention, le première branche 331 est destinée au passage du courant nominal (fonctionnement dit normal) et la seconde branche de passage 332 est destinée à l'établissement et à l'interruption des courants électriques.According to this preferred embodiment of the invention, the first branch 331 is intended for the passage of the nominal current (so-called normal operation) and the second branch 332 is intended for the establishment and interruption of electric currents.

Cette architecture permet alors d'optimiser le dimensionnement de chacune des branches 331, 332 pour la fonction à laquelle elle est dédiée.This architecture then makes it possible to optimize the dimensioning of each of the branches 331, 332 for the function to which it is dedicated.

Selon un exemple de réalisation des contacts fixes 320, tel que représenté sur la figure 8, les contacts fixes 320 destinés à collaborer avec la seconde branche 332 de commutation du contact mobile 330 présentent une en forme de J au niveau des zones de contact 37 avec la seconde branche 332. Ainsi, dans la position de fermeture des contacts 320, 330, le sens du courant électrique circulant dans un contact fixe 320 est opposé au sens du courant électrique circulant dans la seconde branche 332. C'est pourquoi, cette forme de J est destinée à favoriser la commutation des courants. En outre, les zones de contact 37 du contact fixe 320 destinées à être en contact avec les zones de contact 36 de la seconde branche 332 comportent une pastille de contact. Les zones de contact 36 de la seconde branche 332 comportent aussi une pastille de contact. Ces pastilles sont cependant de tailles réduites par rapport à celles d'un contacteur classique vu le faible nombre de commutations.According to an embodiment of the fixed contacts 320, as shown in FIG. figure 8 , the fixed contacts 320 intended to collaborate with the second branch 332 for switching the movable contact 330 have a J-shaped at the contact areas 37 with the second branch 332. Thus, in the closed position of the contacts 320, 330 , the direction of the electric current flowing in a fixed contact 320 is opposite to the direction of the electric current flowing in the second branch 332. This is why this form of J is intended to promote the switching of currents. In addition, the contact areas 37 of the fixed contact 320 intended to be in contact with the contact zones 36 of the second branch 332 comprise a contact pad. The contact areas 36 of the second branch 332 also include a contact pad. These pellets, however, are reduced in size compared to those of a conventional contactor given the small number of switches.

Les contacts fixes 320 destinés à collaborer avec les premières branches 331 du contact mobile présentent une forme droite au niveau des zones de contact 39 avec la première branche 331. Ainsi, dans la position de fermeture des contacts 320, 330, le sens du courant électrique circulant dans un contact fixe 320 est identique au sens du courant électrique circulant dans la première branche 331. C'est pourquoi, cette forme droite est destinée à réduire fortement les risques de répulsion électrodynamique. En outre, compte tenu que les zones de contact 39 des contacts fixes 320 placés en vis-à-vis des zones de contact 40 des premières branches de contact 331 du contact mobile 330 ne sont pas soumis aux altérations liées aux arcs électriques. Lesdites zones 39, 40 sont constituées de cuivre recouvert d'une fine couche d'argent Ag ou d'alliage Argent-Carbone AgC. On entend par « fine couche », une couche de matière d'une épaisseur comprise entre par exemple 10 µm et quelques dizaines de microns. Ceci permet notamment de réduire fortement les volumes d'argent des pastilles de contact présentes dans les contacteurs. De cette manière on réduit fortement la consommation d'une matière première dont les réserves s'épuisent et on diminue simultanément le coût de l'appareil.The fixed contacts 320 intended to collaborate with the first branches 331 of the movable contact have a straight shape at the contact zones 39 with the first branch 331. Thus, in the closed position of the contacts 320, 330, the direction of the electric current circulating in a fixed contact 320 is identical to the direction of the electric current flowing in the first branch 331. Therefore, this straight form is intended to greatly reduce the risk of electrodynamic repulsion. In addition, considering that the contact areas 39 of the fixed contacts 320 placed vis-à-vis the contact areas 40 of the first contact legs 331 of the movable contact 330 are not subject to alterations related to arcs. Said zones 39, 40 consist of copper coated with a thin layer of silver Ag or silver-carbon alloy AgC. By "thin layer" is meant a layer of material having a thickness of between, for example, 10 μm and a few tens of microns. This in particular makes it possible to strongly reduce the silver volumes of the contact pads present in the contactors. In this way, the consumption of a raw material whose reserves are exhausted and the cost of the apparatus is reduced simultaneously.

La première et la seconde branches 331, 332 comportent des axes longitudinaux sensiblement parallèles et décalés l'un par rapport à l'autre selon une direction de déplacement Z du contact mobile 330. Le déplacement en translation du porte contact mobile 38 supportant les première et la seconde branches 331, 332 est réalisé selon une direction perpendiculaire à l'axe longitudinal X.The first and the second branches 331, 332 comprise longitudinal axes that are substantially parallel and offset relative to one another in a direction of displacement Z of the movable contact 330. The displacement in translation of the mobile contact holder 38 supporting the first and second the second limbs 331, 332 are made in a direction perpendicular to the longitudinal axis X.

Lorsque le contacteur est associé à un organe de protection de type fusible ou disjoncteur, si l'on veut garantir un fonctionnement correct de ce produit même après un court-circuit de niveau élevé (50 à 100kA), on peut adjoindre à l'architecture ci-dessus des systèmes de compensation des efforts magnétiques sur les contacts mobiles de passage. Ces systèmes dont le but est de renforcer les efforts de fermeture des contact en utilisant le propre courant circulant dans ceux-ci peuvent selon le calibre du produit prendre différentes forme dont la plus courant est une pièce ferromagnétique en forme de U entourant les premières branches mobiles 331 et solidaire du porte contact mobile 38.When the contactor is associated with a fuse or circuit breaker type protection element, if we want to ensure correct operation of this product even after a high level short circuit (50 to 100kA), we can add to the architecture above systems for compensation of magnetic forces on the movable moving contacts. These systems, the purpose of which is to reinforce the closing forces of the contacts by using the proper current flowing in them, may, depending on the size of the product, take different forms, the most common being a U-shaped ferromagnetic part surrounding the first movable branches. 331 and secured to the movable contact holder 38.

Selon une variante de réalisation du bloc unitaire de commutation telle représenté sur les figures 5B et 7, le porte contact mobile 38 comporte un U magnétique 55 ayant deux branches disposées de manière à ce qu'elles s'étendent selon la direction de déplacement Z pour envelopper au moins une partie des premières branches 331.According to an alternative embodiment of the unit switching unit as represented on the Figures 5B and 7 , the movable contact holder 38 comprises a magnetic U 55 having two branches arranged so that they extend in the direction of displacement Z to envelop at least a portion of the first branches 331.

L'invention est aussi relative à dispositif de commutation 1 tel que notamment un contacteur. Le dispositif de commutation électrique 1 selon l'invention tel que représenté sur la figure 9 comporte un bloc de coupure 100 associé à un bloc d'actionnement 200.

Selon le mode de réalisation représenté sur la figure 9, le contacteur comporte trois pôles électriques, on parle alors de contacteur tripolaire. Un bloc unitaire de coupure 80 est alors associé à chaque pole électrique. Les trois blocs unitaires de coupure 80 sont alors commandés de manière synchronisée par le bloc d'actionnement 200 agissant sur des dispositifs d'actionnement 34 des blocs unitaires de coupure 80. Le dispositif de commutation 1 comporte des borniers de raccordement 500 destinés à être raccordés aux bornes de raccordement 45 des blocs unitaires de coupure 80.The invention also relates to switching device 1 such as in particular a contactor.
