Description

DESCRIPTION DESCRIPTION
TITRE : Dispositif de mise en mouvement simultané d’une pluralité de contacts mobiles d’un contacteur TITLE: Device for simultaneous movement of a plurality of movable contacts of a contactor
L’invention concerne, de manière générale, les boîtiers de distribution d’énergie électrique et, plus particulièrement, les commutateurs pour un tel boîtier, notamment pour aéronef. The invention relates, in general, to electrical energy distribution boxes and, more particularly, to switches for such a box, in particular for aircraft.
Un aéronef possède en général un système électrique d’ alimentation comprenant notamment un circuit de distribution primaire d’énergie électrique. An aircraft generally has an electrical power supply system comprising in particular a primary distribution circuit for electrical energy.
Ce circuit de distribution primaire permet de protéger et de distribuer la puissance électrique provenant de sources internes, par exemple des générateurs ou des batteries, ou de sources externes, vers des modules externes ou vers d’ autres boîtiers de distribution deThis primary distribution circuit protects and distributes electrical power from internal sources, for example generators or batteries, or from external sources, to external modules or to other distribution boxes.
G aéronef. G aircraft.
Un circuit de distribution primaire comprend généralement une partie puissance et une partie commande. A primary distribution circuit generally comprises a power part and a control part.
La partie puissance utilise des boîtiers de distribution qui comportent généralement une connexion de distribution comprenant une ou plusieurs barres de distribution montées en surface sur une platine de support et assurant la distribution de la puissance fournie par des générateurs électriques. The power part uses distribution boxes which generally comprise a distribution connection comprising one or more distribution bars mounted on the surface on a support plate and ensuring the distribution of the power supplied by electric generators.
Des composants de distribution, tels que des commutateurs, sont montés sur la connexion de distribution et, en fonction de leur état ouvert ou fermé, autorisent ou non le passage du courant dans les barres de distribution ou permettent de commuter l’énergie électrique reçue vers une autre barre de distribution ou vers un autre boîtier de distribution d’énergie électrique. Ces commutateurs sont généralement des contacteurs aptes à supporter des courants importants et sont couplés à des moyens de raccordement électrique qui viennent coopérer avec les barres de distribution. Distribution components, such as switches, are mounted on the distribution connection and, depending on their open or closed state, whether or not they allow current to flow through the distribution bars or allow the received electrical energy to be switched to. another distribution bar or to another electrical energy distribution box. These switches are generally contactors capable of withstanding large currents and are coupled to electrical connection means which cooperate with the distribution bars.
Un contacteur, de structure classique, comprend généralement une bobine agissant sur un contact mobile conducteur doté de pastilles de contact conductrices destinées à être couplées à ladite connexion de distribution d’énergie ou à des modules externes. A contactor, of conventional structure, generally comprises a coil acting on a conductive movable contact provided with pads. conductive contacts intended to be coupled to said power distribution connection or to external modules.
Afin de réduire la masse et les dimensions dans les boîtiers de distribution électrique, on utilise généralement des barres d’interconnexion (« bus bar » en anglais) sur lesquelles on peut fixer directement les contacteurs via des contacts électriquement conducteurs fixes, ce qui permet au contacteur d’ assurer ses fonctions usuelles de distribution d’énergie électrique et de protection du réseau électrique. In order to reduce the mass and the dimensions in the electrical distribution boxes, interconnection bars (“bus bar” in English) are generally used on which the contactors can be directly fixed via fixed electrically conductive contacts, which allows the contactor to perform its usual functions of electrical energy distribution and protection of the electrical network.
Pour éviter tout contact superficiel pouvant faire obstacle au passage du courant, il est nécessaire d’ajuster l’effort de pression de contact entre les contacts fixes et mobiles du contacteur. To avoid any superficial contact that could obstruct the flow of current, it is necessary to adjust the contact pressure force between the fixed and moving contacts of the contactor.
Pour ce faire, la position des contacts mobiles est réglée en fonction de la course totale du contacteur. Il s’ agit d’un réglage de la distance entre les contacts fixes et mobiles, communément appelé réglage d’ affirmation. To do this, the position of the movable contacts is adjusted according to the total stroke of the contactor. This is an adjustment of the distance between stationary and movable contacts, commonly referred to as an affirmation adjustment.
Plus particulièrement, on fait varier la surcourse pour comprimer le ressort du contacteur lors de sa fermeture. More particularly, the overtravel is varied in order to compress the spring of the contactor when it is closed.
Ce réglage est effectué simultanément sur une pluralité de contacts mobiles et permet de limiter les dispersions et donc d’ avoir des contacts mobiles synchronisés. This adjustment is carried out simultaneously on a plurality of mobile contacts and makes it possible to limit dispersions and therefore to have synchronized mobile contacts.
Or, ledit réglage est réalisé via un accès situé en dessous du contacteur, ce qui demande l’utilisation d’un nombre important de pièces et augmente donc la complexité de réalisation du système de réglage. L’utilisation de la barre d’interconnexion n’est donc plus avantageuse. However, said adjustment is carried out via an access located below the contactor, which requires the use of a large number of parts and therefore increases the complexity of producing the adjustment system. The use of the interconnection bar is therefore no longer advantageous.
L’enjeu est donc de réussir à assurer le réglage d’ affirmation sans augmenter l’encombrement au sein du contacteur et du boîtier. The challenge is therefore to succeed in ensuring the affirmation setting without increasing the bulk within the contactor and the housing.
Au vu de ce qui précède, l’invention a pour objet un dispositif de mise en mouvement et de réglage simultané d’une pluralité de contacts mobiles électriquement conducteurs d’ au moins un contacteur pour plaque de distribution d’énergie électrique. In view of the above, the object of the invention is a device for setting in motion and simultaneous adjustment of a plurality of electrically conductive movable contacts of at least one contactor for an electrical energy distribution plate.
Le dispositif comprend une tige mobile traversant ledit au moins un contacteur en son centre jusqu’au contact avec l’un des contacts mobiles, la tige étant montée à rotation dans la direction de déplacement desdits contacts mobiles. The device comprises a movable rod passing through said at least one contactor at its center until contact with one of the contacts. movable, the rod being mounted to rotate in the direction of movement of said movable contacts.
Il comporte en outre des moyens de réglage et de blocage en rotation situés sur le haut du contacteur et aptes à coopérer avec la tige dans le sens de la fermeture ou de l’ ouverture du contacteur. It further comprises means for adjusting and locking in rotation located on the top of the contactor and able to cooperate with the rod in the direction of closing or opening of the contactor.
Autrement dit, en coopérant avec les moyens de blocage et de réglage, la tige permet de synchroniser simultanément les contacts mobiles et ainsi éviter les dispersions. In other words, by cooperating with the locking and adjustment means, the rod makes it possible to synchronize the mobile contacts simultaneously and thus to avoid dispersions.
Avantageusement, les moyens de blocage sont configurés pour maintenir ladite tige en position dès que la tige a parcouru un angle de rotation a déterminé. Advantageously, the locking means are configured to keep said rod in position as soon as the rod has gone through a determined angle of rotation.
L’ angle de rotation permet de régler la position des contacts mobiles par rapport aux contacts fixes du contacteur et ainsi éviter tout contact superficiel. En réglant la position du contacteur mobile, on règle donc la distance de surcourse pour comprimer le ressort de rappel lors de la fermeture du contacteur, la surcourse pouvant être déterminée en fonction du type de courant. Par exemple, si le contacteur est traversé par un courant alternatif, on peut avoir une surcourse de 0.75 mm. De préférence, les moyens de de blocage comprennent respectivement un écrou, un contre-écrou et une butée. The angle of rotation adjusts the position of the movable contacts relative to the fixed contacts of the contactor and thus avoid any surface contact. By adjusting the position of the mobile contactor, the overtravel distance is therefore adjusted to compress the return spring when the contactor is closed, the overtravel being able to be determined according to the type of current. For example, if the contactor is crossed by an alternating current, one can have an overtravel of 0.75 mm. Preferably, the locking means respectively comprise a nut, a locknut and a stop.
Préférentiellement, la tige est isolée par un matériau diélectrique. Preferably, the rod is insulated by a dielectric material.
Avantageusement, les moyens de blocage sont accessibles par au moins une extrémité de la tige dudit au moins un contacteur. Advantageously, the locking means are accessible by at least one end of the rod of said at least one contactor.
En fonction de la structure des barres de distribution de courant, les contacteurs peuvent être accessibles par une voire des deux extrémités de la tige. Depending on the structure of the current distribution bars, the contactors may be accessible from one or both ends of the rod.
Plus particulièrement, pour une structure de type barre d’interconnexion, les moyens de blocage sont uniquement accessibles par le côté moteur du contacteur, c’est-à-dire par le dessus, ce qui permet de réduire l’encombrement, la masse et la complexité du montage du système. L’invention a encore pour objet un boîtier de distribution d’énergie électrique comportant au moins une barre de distribution de courant et un ensemble de commutation comprenant au moins un contacteur. Le contacteur comprend un dispositif de mise en mouvement simultané d’une pluralité de ses contacts mobiles tel que décrit ci- dessus. More particularly, for an interconnection bar type structure, the locking means are only accessible from the motor side of the contactor, that is to say from above, which makes it possible to reduce the bulk, the mass and the complexity of mounting the system. A further subject of the invention is an electrical energy distribution box comprising at least one current distribution bar and a switching assembly comprising at least one contactor. The contactor comprises a device for simultaneously setting in motion a plurality of its movable contacts as described above.
D’ autres avantages et caractéristiques de l’invention apparaîtront à l’examen de la description détaillée des modes de mise en œuvre et de réalisation de l’invention, nullement limitatifs, et de la figure annexée sur laquelle : Other advantages and characteristics of the invention will become apparent on examination of the detailed description of the embodiments and embodiments of the invention, which are in no way limiting, and of the appended figure in which:
[fig. l] représente une coupe schématique simplifiée d’un contacteur comprenant un dispositif de mise en mouvement selon un mode de réalisation de l’invention. La figure 1 illustre un exemple de réalisation d’un contacteur conforme à l’invention, désigné par la référence numérique générale 1. [fig. l] shows a simplified schematic section of a contactor comprising a device for setting in motion according to one embodiment of the invention. Figure 1 illustrates an exemplary embodiment of a contactor according to the invention, designated by the general reference numeral 1.
Le contacteur 1 est par exemple intégré dans un boîtier de distribution d’énergie électrique d’un circuit primaire d’un système électrique d’ alimentation pour aéronef (non représentés). Un tel boîtier comprend généralement au moins une barre de distribution de courant continu ou alternatif et une pluralité de contacteurs 1 dont le nombre varie en fonction des besoins. The contactor 1 is for example integrated in an electrical energy distribution box of a primary circuit of an electrical power supply system for aircraft (not shown). Such a housing generally comprises at least one direct or alternating current distribution bar and a plurality of contactors 1, the number of which varies according to needs.
Le contacteur 1 , de structure classique, comprend une bobine agissant sur une pluralité de contacts mobiles conducteurs 2 dotés de pastilles de contact conductrices destinées à être couplées à la connexion de distribution d’énergie ou à des modules externes. The contactor 1, of conventional structure, comprises a coil acting on a plurality of conductive movable contacts 2 provided with conductive contact pads intended to be coupled to the power distribution connection or to external modules.
Le contacteur comprend une première zone ZI située côté moteur et une deuxième zone Z2 qui comprend les contacts mobiles 2 ici au nombre de trois. A l’extrémité de la première zone ZI vient s’insérer, au centre du contacteur 1 , un dispositif de mise en mouvement simultané des contacts mobiles 2. Le dispositif comprend une tige 3 s’étendant selon un axe X-X’ jusqu’ au contact avec l’un des contacts mobiles, ici le contact mobile 2 central. The contactor comprises a first zone ZI located on the motor side and a second zone Z2 which comprises the movable contacts 2 here three in number. At the end of the first zone ZI is inserted, in the center of the contactor 1, a device for simultaneous movement of the mobile contacts 2. The device comprises a rod 3 extending along an axis X-X 'up to contact with one of the movable contacts, here the central movable contact 2.
La tige 3 est montée à rotation dans la direction de déplacement des contacts mobiles 2 et isolée par un matériau diélectrique 6. The rod 3 is mounted to rotate in the direction of movement of the movable contacts 2 and insulated by a dielectric material 6.
Afin de régler l’ affirmation, la tige 3 peut être vissée ou dévissée pour réduire ou augmenter la distance entre les contacts mobiles 2 et fixes du contacteur 1 , correspondant à un angle de rotation a déterminé. In order to adjust the affirmation, the rod 3 can be screwed or unscrewed to reduce or increase the distance between the mobile 2 and fixed contacts of the contactor 1, corresponding to a determined angle of rotation.
Pour ce faire, le dispositif de mise en mouvement comprend des moyens de blocage et de réglage aptes à coopérer avec la tige 3 et la maintenir en position dans le sens de la fermeture et de l’ ouverture du contacteur 1 . To do this, the device for setting in motion comprises locking and adjustment means capable of cooperating with the rod 3 and maintaining it in position in the direction of closing and opening of the contactor 1.
Dans cet exemple, les moyens de blocage comprennent un écrou 4 et un contre-écrou en appui contre l’écrou 4, apte à l’immobiliser. Les moyens de blocage comprennent également une butée 5 sur laquelle la tige 3 est maintenue plaquée lors de la fermeture du contacteur 1 via le ressort de rappel du contacteur 1. In this example, the locking means comprise a nut 4 and a locknut bearing against the nut 4, able to immobilize it. The locking means also comprise a stop 5 on which the rod 3 is held pressed when the contactor 1 is closed via the return spring of the contactor 1.
Autrement dit, la butée 5 permet de limiter le mouvement de la tige 3 en lui faisant obstacle une fois le contacteur 1 fermé. Ainsi, le dispositif de mise en mouvement simultané, dont l’ accès se situe dans la première zone Zl , permet de régler l’ affirmation des trois contacts mobiles 2 simultanément et limiter les dispersions entre eux. In other words, the stop 5 makes it possible to limit the movement of the rod 3 by obstructing it once the contactor 1 is closed. Thus, the device for simultaneous movement, the access to which is located in the first zone Zl, makes it possible to adjust the assertion of the three mobile contacts 2 simultaneously and to limit the dispersions between them.
Alternativement, dans le cas d’un contacteur disposé sur une structure différente d’une barre d’interconnexion, l’accès au dispositif peut également se faire par la deuxième zone Z2. Dans ce cas, l’homme du métier saura installer le dispositif dans ladite zone en remplaçant si besoin les moyens de blocage cités à titre d’exemple par d’ autres pièces plus adaptées. Alternatively, in the case of a contactor arranged on a structure other than an interconnection bar, access to the device can also be via the second zone Z2. In this case, a person skilled in the art will know how to install the device in said zone by replacing, if necessary, the blocking means mentioned by way of example with other more suitable parts.
