Description
La présente invention concerne un dispositif de commande d'ouverture et/ou de fermeture en particulier pour un appareil de coupure tel un disjoncteur conformément au préambule de la revendication 1 (voir FR-A-1 324 466 par example).The present invention relates to an opening and / or closing control device in particular for a breaking device such as a circuit breaker in accordance with the preamble of claim 1 (see FR-A-1 324 466 for example).
On connaít un dispositif comprenant une armature montée linéairement coulissante dans un support, deux aimants permanents agencés de part et d'autre de l'axe de coulissement de l'armature et un ou plusieurs enroulement(s) monté(s) autour de l'armature et apte(s) à générer un champ magnétique parallèle à l'axe de coulissement précité. Il résulte de ce déplacement linéaire de l'armature, qu'un entrefer relativement important est à vaincre au début du déplacement de l'armature vers la position active. Il en résulte qu'une grande quantité d'énergie (ampère-tours) au départ est nécessaire pour entraíner l'armature.We know a device comprising a linearly sliding armature mounted in a support, two permanent magnets arranged on either side of the sliding axis of the armature and one or more winding (s) mounted around the armature and suitable for generate a magnetic field parallel to the above sliding axis. It follows from this linear displacement of the reinforcement, which a relatively large air gap has to be overcome start of movement of the armature to the active position. As a result, a large amount of energy (ampere-turns) at the start is necessary to train the frame.
D'autre part, pendant son mouvement linéaire, l'armature tend à se déplacer latéralement, essayant de se placer dans une position dans laquelle le champs est minimum, d'où il résulte que des frottements sont susceptibles d'être générés sur les paliers pouvant engendrer des efforts importants sur lesdits paliers.On the other hand, during its linear movement, the armature tends to move laterally, trying to get into a position where the field is minimum, where it results that friction is likely to be generated on the bearings which can cause significant efforts on said bearings.
La présente invention résout ces problèmes et propose un dispositif de commande de conception simple, dans lequel l'énergie nécessaire au départ est diminuée et présentant un rendement important, ainsi qu'un disjoncteur équipé d'un tel dispositif.The present invention solves these problems and proposes a device for controlling simple design, in which the energy required at the start is reduced and presenting a high efficiency, as well as a circuit breaker equipped with such a device.
A cet effet, la présente invention a pour objet un dispositif du genre précédemment mentionné, ce dispositif étant caractérisé en ce que l'armature précitée est montée mobile en rotation entre deux butées ménagées dans le support, lesdites butées délimitant respectivement les deux positions précitées. To this end, the present invention relates to a device of the kind previously mentioned, this device being characterized in that the aforementioned armature is mounted movable in rotation between two stops formed in the support, said stops delimiting respectively the two aforementioned positions.
Selon une réalisation particulière de l'invention, l'armature comprend une pièce de forme allongée présentant deux extrémités opposées de forme arquée, ladite pièce étant montée en rotation autour d'un axe s'étendant perpendiculairement à la direction longitudinale de l'armature.According to a particular embodiment of the invention, the frame comprises a shaped part elongated having two opposite ends of arcuate shape, said part being mounted in rotation about an axis extending perpendicular to the longitudinal direction of the armature.
Selon une caractéristique particulière, le dispositif comporte deux enroulements aptes à générer respectivement lorsqu'excités, deux champs magnétiques de sens opposé, de manière à entraíner en rotation l'armature respectivement dans un sens pour réaliser la manoeuvre d'ouverture des contacts, et dans un sens opposé pour réaliser une manoeuvre de fermeture des contacts.According to a particular characteristic, the device comprises two windings capable of generate respectively when excited, two magnetic fields of opposite direction, of so as to rotate the armature respectively in one direction to achieve the opening operation of the contacts, and in an opposite direction to carry out an operation of contact closure.
Selon une autre caractéristique, les deux enroulements sont situés chacun entre les deux aimants, respectivement d'un côté et de l'autre de l'axe de manière à être décalés mutuellement et angulairement d'un angle d'environ 180°.According to another characteristic, the two windings are each located between the two magnets, respectively on one side and the other of the axis so as to be offset mutually and angularly at an angle of about 180 °.
L'invention a encore pour objet un disjoncteur comprenant les caractéristiques précédemment mentionées prises seules ou en combinaison.The invention also relates to a circuit breaker comprising the characteristics previously mentioned taken alone or in combination.
Mais d'autres avantages et caractéristiques apparaítront mieux dans la description détaillée
qui suit et se réfère aux dessins annexés donnés uniquement à titre d'exemple et dans
lesquels :
Sur les figures, on voit un dispositif de manoeuvre destiné à assurer l'ouverture des contacts d'un appareil de coupure tel un disjoncteur moyenne tension placé dans un circuit électrique, lors de l'apparition d'un défaut électrique tel une surtension dans ledit circuit. In the figures, we see an operating device intended to ensure the opening of the contacts a breaking device such as a medium voltage circuit breaker placed in a circuit electrical, upon the appearance of an electrical fault such as an overvoltage in said circuit.
Sur les figures 1 et 2, on voit que selon l'invention le dispositif comprend une armature 9 de
forme générale allongée présentant deux extrémités de forme arquée 9a,9b, solidarisée à une
tige d'actionnement 10 s'étendant perpendiculairement à la direction longitudinale de
l'armature 9. Cette armature 9 est montée libre en rotation dans un bloc support 13 entre
deux positions délimitées par des butées 11,12 formées dans ledit support 13. Le bloc
support 13 comporte donc à cet effet, deux surfaces de guidage en rotation 14,15 de
l'armature, de forme circulaire, disposées de manière opposée par rapport à l'axe X de
rotation de l'armature 9, et s'étendant chacune entre les deux butées 11,12, lesdites surfaces
étant aptes à coopérer avec les deux extrémités précitées 9a,9b de l'armature 9. Ces
butées 11,12 sont décalées angulairement l'une de l'autre, par rapport à l'axe X de rotation
de l'armature, d'un angle d'environ 50°. Les deux butées 11,12 sont de forme
complémentaire aux parties 9c,9d de l'armature 9 destinées à être amenées en contact avec
lesdites butées. Chacune de ces butées 11,12 est constituée par deux
parties 11a,11b,12a,12b de même orientation, disposées symétriquement l'une par rapport à
l'autre, par rapport à l'axe X de rotation de l'armature 9. Dans ce bloc support 13 sont
agencés deux aimants permanents 16,17 disposés de manière opposée l'un par rapport à
l'autre et par rapport audit axe X, chacun le long de l'une des deux surfaces de guidage
précitées 14,15, sensiblement au milieu de la circonférence de ces surfaces 14,15, lesdits
aimants 16,17 étant alors décalés mutuellement et angulairement par rapport à l'axe X d'un
angle d'environ 180°. Le sens d'aimantation de ces aimants 16,17 est tel que représenté par
les flèches sur les figures 1 et 2. Le dispositif comporte en outre deux bobines 18,19
constituées chacune par un seul enroulement, lesdites bobines 18,19 étant situées de part et
d'autre de l'armature 9 entre les surfaces de guidage 14,15 en étant décalées d'un angle
d'environ 180° l'une par rapport à l'autre autour de l'axe X, chacune des bobines étant
située entre les deux aimants 16,17. Ainsi, les aimants et bobines sont décalés
successivement et alternativement autour de l'axe d'un angle d'environ de 90°.In FIGS. 1 and 2, it can be seen that according to the invention the device comprises a
Sur les figures 3 et 4, on voit que la tige d'actionnement 10 est reliée mécaniquement
directement à l'arbre 20 du disjoncteur.In Figures 3 and 4, we see that the
Le fonctionnement du dispositif de l'invention va être décrit brièvement dans ce qui suit en référence aux figures :The operation of the device of the invention will be described briefly in the following in reference to figures:
En fonctionnement normal du circuit, le dispositif est dans la position disjoncteur fermé
représentée sur la figure 1. Dans cette position, l'armature 9 est en appui contre la première
butée 11a,11b et retenue dans cette position par les deux aimants permanents 16,17. Lors
de l'apparition d'un ordre d'ouverture, l'énergie fournie à la bobine correspondante 18
engendre l'excitation de cette dernière jusqu'à ce que la force d'attraction des aimants
permanents 16,17 soit inférieure à la force associée au champs magnétique engendré par la
bobine. Alors, l'armature 9 est entraínée en rotation dans le sens horaire. Au début de ce
mouvement, l'entrefer de départ f est voisin de zéro, le seul entrefer influant e étant
constant et d'une valeur faible. Il en résulte que l'énergie nécessaire au départ pour que
l'armature 9 se décolle de la butée 11 est faible. Le mouvement poursuivi de rotation de
l'armature 9 provoque une rotation correspondante de la tige de déclenchement 10
entraínant l'ouverture des contacts 21,22 du disjoncteur, et par suite l'ouverture du circuit
électrique. Lorsque l'armature 9 arrive au contact de la seconde butée 12 (12a,12b), le
courant traversant la bobine d'ouverture 18 est interrompu. Dans cette position du
dispositif, représentée sur la figure 2, l'armature 9 est maintenue contre la seconde butée 12
par les deux aimants permanents 16,17.In normal circuit operation, the device is in the closed circuit breaker position
shown in Figure 1. In this position, the
Afin de réaliser la fermeture du circuit, un courant est envoyé dans la bobine de
fermeture 19. Lorsque le champ magnétique correspondant crée par la bobine 19 de
fermeture est supérieur au champ crée par les aimants permanents 16,17, l'armature 9 se
déplace en sens inverse, c'est à dire anti-horaire, jusqu'à ce que celle-ci atteigne la première
butée 11, position dans laquelle elle est retenue de nouveau par les aimants
permanents 16,17, représentée sur la figure 1.In order to close the circuit, a current is sent to the coil
closing 19. When the corresponding magnetic field created by the
On notera que, bien que dans la réalisation précédemment décrite, la commutation pour l'ouverture est réalisée par l'une seulement des deux bobines, la réalisation d'un dispositif dans lequel la commutation pour l'ouverture serait réalisée par l'excitation de deux bobines montées en série ou en parallèle peut être avantageusement envisagée sans sortir du cadre de l'invention.It will be noted that, although in the embodiment described above, the switching for the opening is carried out by only one of the two coils, the production of a device in which the switching for the opening would be carried out by the excitation of two coils mounted in series or in parallel can advantageously be envisaged without departing from the scope of the invention.
On notera également que l'ordre d'ouverture pourra être envoyé par exemple par une action volontaire ayant pour but de séparer les contacts, ou bien directement à la suite de l'apparition d'un défaut électrique dans le circuit.Note also that the opening order can be sent for example by an action intended to separate the contacts, or directly following the appearance of an electrical fault in the circuit.
De l'agencement des aimants, c'est à dire du sens de leur aimantation, dépend la valeur des
couples de fermeture et d'ouverture.
Ainsi, comme ceci est le cas dans la réalisation décrite précédemment, le sens d'aimantation
pourra être choisi de manière que le couple de fermeture soit important et le couple
d'ouverture faible ( le champ de la bobine d'ouverture se trouvant dans le sens des aimants).The value of the closing and opening torques depends on the arrangement of the magnets, that is to say the direction of their magnetization.
Thus, as is the case in the embodiment described above, the direction of magnetization can be chosen so that the closing torque is high and the opening torque low (the field of the opening coil being in the sense of magnets).
On notera que ce dispositif pourra avantageusement être utilisé pour assurer entre autres la commande de disjoncteurs à vide. It will be noted that this device can advantageously be used to ensure inter alia the vacuum circuit breaker control.
On obtient grâce à l'invention un actionneur stable dans les deux positions limites sans
alimentation des bobines, l'énergie électrique n'étant fournie aux bobines que pendant le
déplacement de l'armature.
La réalisation du bistable en rotation conduit à ce que tous les efforts soient équilibrés, d'où
un rendement plus important du dispositif sans que des efforts trop importants soient
engendrés sur les paliers.Thanks to the invention, a stable actuator is obtained in the two limit positions without supplying the coils, the electrical energy being supplied to the coils only during the movement of the armature.
The realization of the bistable in rotation leads to all the forces being balanced, hence a greater yield of the device without too great forces being generated on the bearings.
Les autres avantages du dispositif liés à son architecture sont les suivants :
- L'actionneur peut être monté en rotation directement sur l'arbre du dispositif à manoeuvrer, ce qui permet d'éviter les renvois de palonnier.
- L'intégration du dispositif dans l'architecture du disjoncteur est facilitée et la réalisation d'ensemble est simple.
- Les aimants et les deux butées incorporées dans le circuit, réalisent avec l'armature un entrefer minimum permettant d'obtenir des efforts de maintien importants, entre le rotor et le stator, sans source d'énergie supplémentaire.
- The actuator can be mounted in rotation directly on the shaft of the device to be maneuvered, which makes it possible to avoid lifting beam returns.
- The integration of the device into the architecture of the circuit breaker is facilitated and the overall implementation is simple.
- The magnets and the two stops incorporated in the circuit, achieve with the armature a minimum air gap allowing to obtain significant holding forces, between the rotor and the stator, without additional energy source.
On notera que les parties externes E de l'actionneur seront avantageusement réalisées de manière à limiter les courants induits.It will be noted that the external parts E of the actuator will advantageously be made of so as to limit the induced currents.
