L'invention est aussi relative à un dispositif de coupure comportant au moins un bloc unitaire de coupure. The invention also relates to a cut-off device comprising at least one unitary breaking unit.
ETAT DE LA TECHNIQUE ANTERIEURE STATE OF THE PRIOR ART
Dans un contacteur destiné à la commande des courants alternatifs, lors de la phase d'interruption des courants, un arc apparaît au niveau des contacts. Cet arc nécessaire à la coupure doit être refroidi et chassé rapidement de la zone des contacts afin de réduire l'érosion des pastilles de contact et d'augmenter la tenue diélectrique inter-contacts, permettant ainsi l'interruption du courant au passage par zéro naturel de celui ci. Dans les contacteurs de calibre d'intensité inférieur à cent ampères, on utilise généralement des pièces magnétiques appelées « U de soufflage ». Ces U de soufflage couplés à des contacts dits « droits » ont pour inconvénient d'être parcourus par un courant dont le sens à tendance à pousser le pied d'arc dans le sens inverse de celui recherché pour répondre au besoin d'évacuation de l'arc de la zone des contacts. In a contactor for the control of alternating currents, during the phase of interruption of currents, an arc appears at the level of the contacts. This arc necessary for the cutoff must be cooled and driven out quickly from the area of the contacts in order to reduce the erosion of the contact pads and to increase the inter-contact dielectric strength, thus allowing the interruption of the current at the natural zero crossing. of this one. In contactors with a rating of less than one hundred amperes, magnetic parts called "U of blowing" are generally used. These U blowing coupled to so-called "right" contacts have the disadvantage of being traversed by a current whose direction tends to push the foot of the arc in the opposite direction to that sought to meet the need for evacuation of the arc of the contact area.
L'autre inconvénient est relatif l'effort magnétique créé sur l'arc. En effet, dés que l'effort magnétique créé sur l'arc par le U est supérieur à l'effort inverse du au sens de passage du courant, l'arc vient alors sur le passage de courant en cuivre et risque ainsi de provoquer une forte érosion du support contact. The other disadvantage is relative to the magnetic stress created on the arc. Indeed, as soon as the magnetic force created on the arc by the U is greater than the reverse force force in the direction of passage of the current, the arc then comes on the copper current passage and thus may cause a strong erosion of the contact support.
EXPOSE DE L'INVENTION SUMMARY OF THE INVENTION
L'invention vise donc à remédier aux inconvénients de l'état de la technique, de manière à proposer un bloc de coupure comportant des moyens de coupure efficaces et de faible encombrement.

De préférence, les deux flasques latéraux parallèles d'une chambre d'extinction d'arc s'étendent selon une direction parallèle au plan longitudinal médian de manière à encadrer entièrement la zone de contact du contact mobile.

Avantageusement, la corne d'arc forme un angle d'ouverture par rapport au déflecteur supérieur métallique, l'angle d'ouverture étant supérieur à 5°.

DESCRIPTION DETAILLEE D'UN MODE DE REALISATION DETAILED DESCRIPTION OF AN EMBODIMENT
Tel que représenté sur la figure 8, le bloc unitaire de coupure 80 comprend un boîtier 31 en matériau plastique moulé dans lequel sont disposés des contacts électriques. As shown in FIG. 8, the unitary cutoff unit 80 comprises a casing 31 made of molded plastic material in which electrical contacts are arranged.
De préférence, le boîtier 31 est formé de deux demi-coques 80A assemblées pour former un ensemble de forme sensiblement parallélépipédique se développant selon un plan longitudinal XZ. Le boîtier 31 comporte alors deux faces principales 81 disposées de manière parallèles au plan longitudinal médian XZ. Ledit boîtier comprend en outre deux faces latérales 82, une face supérieure 83 et une face inférieure 84. Preferably, the housing 31 is formed of two assembled half-shells 80A to form an assembly of substantially parallelepiped shape developing along a longitudinal plane XZ. The housing 31 then has two main faces 81 arranged parallel to the median longitudinal plane XZ. Said housing further comprises two lateral faces 82, an upper face 83 and a lower face 84.
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.
Le bloc unitaire de coupure 80 comprend des moyens électriques de coupure 30 comprenant au moins un contact fixe 32 comportant une zone de contact électrique 37. De préférence, tel que représenté sur les figures 1 et 2, les moyens électriques de coupure 30 comprennent deux contacts fixes 32. Les contacts fixes 32 comportent respectivement une zone de contact électrique 37. The unitary breaking block 80 comprises electrical breaking means 30 comprising at least one fixed contact 32 comprising an electrical contact zone 37. Preferably, as shown in FIGS. 1 and 2, the electrical breaking means 30 comprise two contacts. The fixed contacts 32 respectively comprise an electrical contact zone 37.
Les moyens de coupure comportent un contact mobile 33 comportant un corps allongé suivant un axe longitudinal X et ayant au moins une extrémité comportant une zone de contact 36 pouvant collaborer avec une zone de contact 37 d'un contact fixe 32. De préférence, tel que représenté sur les figures 1 et 2, les moyens électriques de coupure 30 comprennent un pont mobile de contact 33 comportant un corps allongé suivant un axe longitudinal X. Ledit pont a deux extrémités. Chaque extrémité comporte une zone de contact 36 pouvant collaborer avec une zone de contact 37 d'un contact fixe 32 dans une position de fermeture des moyens de coupure. Dans cette position de fermeture, un moyen élastique 25, tel que notamment un ressort hélicoïdal, permet d'assurer entre les zones de contact 36 et 37, une pression de contact suffisante pour garantir le passage du courant dans de bonnes conditions. The cut-off means comprise a movable contact 33 comprising an elongate body along a longitudinal axis X and having at least one end comprising a contact zone 36 capable of collaborating with a contact zone 37 of a fixed contact 32. Preferably, such as shown in Figures 1 and 2, the electrical breaking means 30 comprise a movable contact bridge 33 having an elongated body along a longitudinal axis X. Said bridge has two ends. Each end has a contact zone 36 which can collaborate with a contact zone 37 of a fixed contact 32 in a closed position of the breaking means. In this closed position, an elastic means 25, such as in particular a helical spring, ensures between the contact zones 36 and 37, a contact pressure sufficient to ensure the passage of the current in good conditions.
Des plages de raccordement droites 45 relient respectivement lesdits contacts fixes 32 à une borne électrique. Straight connection pads 45 respectively connect said fixed contacts 32 to an electrical terminal.
Le pont mobile de contact 33, 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 33 selon une direction perpendiculaire à l'axe longitudinal X. Le pont mobile de contact 33 se déplace entre une position d'ouverture et une position de fermeture des contacts électriques. The movable contact bridge 33 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 translational movement of the bridge movable contact 33 in a direction perpendicular to the longitudinal axis X. The movable contact bridge 33 moves between an open position and a closed position of the electrical contacts.
On définit ainsi deux volumes d'ouverture 35 correspondant à l'espace dans lequel sont disposées une zone de contact 37 d'un contact fixe 32 et une zone de contact 36 associée au contact mobile 33. Two opening volumes 35 corresponding to the space in which a contact zone 37 of a fixed contact 32 and a contact zone 36 associated with the moving contact 33 are thus defined.
En outre, chaque volume d'ouverture 35 est 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 68 en matériau ferromagnétique. Les deux flasques latéraux 68 sont parallèles et placés de part et d'autre d'un plan longitudinal médian XZ. Les deux flasques latéraux 68 sont disposés de manière à encadrer une des extrémités du pont mobile 33 sur tout son déplacement entre la position d'ouverture et la position de fermeture. Autrement dit, les deux flasques latéraux 68 sont espacés l'un de l'autre pour autoriser le déplacement du pont mobile de contact 33. Les parois internes desdits flasques 38 comporte une couche 38 de matériau isolant. Le positionnement des couches 38 de matériau isolant sur les flasques 68 permet d'éviter l'accrochage de l'arc sur les parois internes desdits flasques 68. Ces couches 38 sont de préférence en matériau gazogène. La chambre d'extinction 24 est délimitée aussi par une paroi postérieure 72 placée perpendiculairement au plan XZ. Ladite paroi postérieure est éloignée du volume d'ouverture 35 pour être positionnée à l'opposé d'un volume d'ouverture des zones de contact 36, 37. La paroi postérieure 72 relie les deux flasques latéraux 68 de façon à former un ensemble métallique sensiblement en forme de U. La paroi postérieure 72 relie les deux flasques sur une partie de leur hauteur. In addition, each opening volume 35 is associated with an arc extinguishing chamber 24. Each arc extinguishing chamber 24 opening on the opening volume 35 is delimited by two flanges 68 of material ferromagnetic. The two lateral flanges 68 are parallel and placed on either side of a median longitudinal plane XZ. The two lateral flanges 68 are arranged to frame one of the ends of the movable bridge 33 over its entire displacement between the open position and the closed position. In other words, the two side flanges 68 are spaced from each other to allow the displacement of the movable contact bridge 33. The inner walls of said flanges 38 comprises a layer 38 of insulating material. The positioning of the layers 38 of insulating material on the flanges 68 avoids the attachment of the arc on the inner walls of said flanges 68. These layers 38 are preferably made of gas-forming material. The extinction chamber 24 is also delimited by a rear wall 72 placed perpendicular to the XZ plane. Said posterior wall is remote from the opening volume 35 to be positioned opposite an opening volume of the contact zones 36, 37. The rear wall 72 connects the two lateral flanges 68 so as to form a metal assembly substantially U-shaped. The rear wall 72 connects the two flanges on part of their height.
De préférence, selon un mode particulier de réalisation, les deux flasques latéraux 68 s'étendent selon une direction parallèle au plan longitudinal médian XZ de manière à encadrer entièrement la zone de contact 36 du pont mobile de contact 33. Plus précisément, les deux flasques latéraux 68 s'étendent de manière enfermer complément la zone de contact 36 du pont mobile de contact 33 à l'intérieur de la chambre d'extinction d'arc 24. Autrement dit, le développement des flasques en longueur permet de fermer latéralement chaque volume d'ouverture 35 de manière à canaliser l'échappement de particules ionisées au moment de l'ouverture des contacts électriques. Preferably, according to a particular embodiment, the two lateral flanges 68 extend in a direction parallel to the median longitudinal plane XZ so as to completely frame the contact zone 36 of the movable contact bridge 33. More specifically, the two flanges side walls 68 extend so enclose complement the contact zone 36 of the movable contact bridge 33 inside the arc extinguishing chamber 24. In other words, the development of the flanges in length allows to close each opening volume laterally 35 so as to channel the escape of ionized particles at the time of opening of the electrical contacts.
Selon un mode préférentiel de réalisation de l'invention, la paroi de chaque chambre d'extinction d'arc 24 comporte un déflecteur supérieur métallique 69. Tel que représenté sur les figures 3 à 6, ledit déflecteur relie électriquement un contact fixe 32 à une paroi postérieure 72 pour former une partie supérieure de la paroi métallique de ladite chambre d'extinction. According to a preferred embodiment of the invention, the wall of each arc extinguishing chamber 24 comprises a metal upper baffle 69. As shown in FIGS. 3 to 6, said baffle electrically connects a fixed contact 32 to a posterior wall 72 to form an upper portion of the metal wall of said extinguishing chamber.
Selon une variante de réalisation, le pont mobile de contact 33 comporte des cornes d'arc 39 à chacune des deux extrémités. Lesdites cornes d'arc s'étendent au-delà des zones de contact en direction des parois postérieures 72 des chambres d'extinction d'arc 24. A titre d'exemple de réalisation, les cornes d'arc 39 sont inclinées par rapport à l'axe longitudinal X du pont mobile de contact 33. Plus précisément, les cornes d'arc 39 forment un angle d'ouverture Θ par rapport au déflecteur supérieur 69 métallique. L'angle d'ouverture (Θ) est de préférence supérieur à 5°. According to an alternative embodiment, the movable contact bridge 33 comprises arc horns 39 at each of the two ends. Said arc horns extend beyond the contact zones towards the rear walls 72 of arc extinguishing chambers 24. As an example of embodiment, the arc horns 39 are inclined with respect to the longitudinal axis X of the movable contact bridge 33. More specifically, the arc horns 39 form an opening angle Θ relative to the upper metal deflector 69. The opening angle (Θ) is preferably greater than 5 °.
Selon une variante de réalisation non représenté, chaque déflecteur supérieur 69 est bordé latéralement par couche en matériau isolant de préférence gazogène. L'appareillage fonctionne de la manière suivante. Lors de l'apparition d'un arc électrique au moment de la séparation des contacts, un champ électromagnétique est induit par le courant circulant dans les conducteurs, notamment dans les contacts fixes 32, le pont mobile contact 33 et l'arc. Ledit champ est induit entre les flasques 68 de l'ensemble ferromagnétique sensiblement en forme de U. Ce champ magnétique crée alors une force électrodynamique sur l'arc électrique. Cette force pousse l'arc dans la chambre d'extinction d'arc 24 en direction de la paroi postérieure 72 métallique. According to an alternative embodiment not shown, each upper baffle 69 is laterally bordered by a layer of preferably gas-forming insulating material. The apparatus operates in the following manner. During the occurrence of an electric arc at the time of the separation of the contacts, an electromagnetic field is induced by the current flowing in the conductors, in particular in the fixed contacts 32, the movable contact bridge 33 and the arc. This field is induced between the flanges 68 of the substantially U-shaped ferromagnetic assembly. This magnetic field then creates an electrodynamic force on the electric arc. This force pushes the arc in the arc extinction chamber 24 towards the rear wall 72 metal.
Le pied d'arc peut alors sauter sur le déflecteur supérieur 69 évitant ainsi une usure prématurée des contacts. L'arc se positionne alors entre la corne 39 et la paroi 72 pour y être refroidi. Selon un mode de réalisation particulier tel que représenté sur la figure, le déflecteur supérieur 69 comporte de préférence des pattes de sertissage 77 destinées à venir collaborer avec des encoches présentes le contact électrique fixe 32. Ce sertissage permet d'assurer une continuité électrique entre le contact fixe 32 et le déflecteur supérieur 69. The arch foot can then jump on the upper deflector 69 thus avoiding premature wear of the contacts. The arc is then positioned between the horn 39 and the wall 72 to be cooled. According to a particular embodiment as shown in the figure, the upper baffle 69 preferably comprises crimping tabs 77 intended to collaborate with notches present the fixed electrical contact 32. This crimping ensures electrical continuity between the fixed contact 32 and upper deflector 69.
L'invention est aussi relative à dispositif de coupure 100 tel que notamment un contacteur. Le dispositif de coupure comporte alors au moins un bloc unitaire 80 de coupure tel que défini ci-dessus. The invention also relates to a cut-off device 100 such as in particular a contactor. The cutoff device then comprises at least one unit block 80 of cutoff as defined above.
Selon un mode de réalisation, le dispositif de coupure 100 peut être destiné à un contacteur multipolaire. Ledit contacteur comporte alors plusieurs blocs de coupure identiques et tous les dispositifs d'actionnement 34 desdits dispositifs peuvent être entraînés par un actionneur de type électro-aimant. According to one embodiment, the cut-off device 100 may be intended for a multipole contactor. Said contactor then comprises several identical breaking blocks and all the actuating devices 34 of said devices can be driven by an electromagnet-type actuator.
Le dispositif comporte en outre un sous-ensemble de commande 104 des dispositifs d'actionnement 34 des blocs unitaires de coupure 80. Le sous- ensemble 104 peut être un actionneur électromagnétique lorsqu'il est destiné à commander des blocs de coupure d'un contacteur. Le sous-ensemble 104 peut être un mécanisme lorsqu'il est destinée commander des blocs de coupure d'un disjoncteur. The device further comprises a control subassembly 104 of the actuating devices 34 of the unitary cut-off units 80. The subassembly 104 may be an electromagnetic actuator when it is intended to control switchgear blocks of a contactor . The subassembly 104 may be a mechanism when it is intended to control breaker blocks of a circuit breaker.
Le dispositif de coupure 100 comporte des borniers de raccordements 105 destinés à être raccordés aux bornes de raccordement 45 dudit au moins bloc de coupure. The cut-off device 100 comprises connection terminals 105 intended to be connected to the connection terminals 45 of the at least one breaking block.
Tel que représenté sur la figures 8, le dispositif de coupure comporte trois blocs unitaires de coupure 80. Les trois blocs unitaires de coupure 80 sont alors commandés de manière synchronisée par le sous-ensemble de commande 104 agissant sur les dispositifs d'actionnement 34 des blocs unitaires de coupure.
