Mais d'autres avantages et caractéristiques de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés donnés uniquement à titre d'exemple et dans lesquels :

  • La figure 1 est une vue en perspective, partielle, illustrant un palonnier supportant un contact mobile appartenant à un appareil de protection électrique selon l'invention, dans une position dite ligne de l'appareil,
  • La figure 2 est une vue partielle illustrant schématiquement la zone de contact entre le contact fixe et le contact mobile,
  • La figure 3 est une vue schématique illustrant le fonctionnement du dispositif de réglage selon l'invention, et
  • Les figures 4 et 5 sont des vues schématiques illustrant deux positions de réglage différentes de la position de l'arbre de manoeuvre.
But other advantages and features of the invention will become more apparent in the detailed description which follows and refers to the accompanying drawings given solely by way of example and in which:
  • The figure 1 is a perspective view, partial, illustrating a beam supporting a movable contact belonging to an electrical protection device according to the invention, in a position called line of the apparatus,
  • The figure 2 is a partial view schematically illustrating the contact zone between the fixed contact and the moving contact,
  • The figure 3 is a schematic view illustrating the operation of the adjustment device according to the invention, and
  • The Figures 4 and 5 are schematic views illustrating two different adjustment positions of the position of the operating shaft.

Sur la figure 1, on voit un palonnier 1 supportant un contact mobile 2 appartenant à un appareil de protection électrique moyenne tension selon l'invention. Ce palonnier 1 est entraîné en rotation par l'intermédiaire d'un arbre de manoeuvre 3 au moyen d'un mécanisme comportant une bielle de commande 4. Cette bielle de commande 4 est destinée à entraîner une bielle d'entraînement 5 de l'arbre de manoeuvre 3 du palonnier 1 entre une première position dans laquelle le palonnier est dans une première position dite de ligne dans laquelle son contact mobile 2 est en contact avec un contact fixe 6 de l'appareil, et une seconde position dans laquelle ce contact mobile 2 et ce contact fixe 6 sont séparés.On the figure 1 , we see a rudder 1 supporting a movable contact 2 belonging to a medium voltage electrical protection device according to the invention. This rudder 1 is rotated by means of an operating shaft 3 by means of a mechanism comprising a control rod 4. This control rod 4 is intended to drive a drive rod 5 of the shaft operating mechanism 3 of the rudder 1 between a first position in which the rudder is in a first so-called line position in which its movable contact 2 is in contact with a fixed contact 6 of the apparatus, and a second position in which this moving contact 2 and this fixed contact 6 are separated.

L'entraînement de la bielle d'entraînement 5 par la bielle de commande 4 est réalisé selon l'invention par l'intermédiaire d'un dispositif de réglage. Ce dispositif de réglage comporte une première bielle 7 reliée de manière articulée par l'une, dite première 7a, de ses extrémités, à la bielle d'entraînement 5, et comportant à une autre extrémité dite seconde 7b, un axe 8 monté dans une lumière 9 prévue à l'extrémité dite première10a d'une seconde bielle 10 dont la seconde extrémité 10b est reliée de manière articulée à la bielle de commande 4 appartenant au mécanisme, cette seconde bielle étant montée librement rotative, entre ces deux extrémités 10a,10b, autour de l'arbre de manoeuvre 3 du palonnier 1. Le déplacement de l'axe 8 dans la lumière 9 est apte à entraîner le déplacement en rotation de la première bielle 7, et donc de la bielle d'entraînement 5 de l'arbre de manoeuvre 3, par l'intermédiaire de dentures 11 prévues d'une part, sur la bielle d'entraînement 5, et d'autre part, sur l'arbre de manoeuvre 3, ce qui entraîne une modification de la position en rotation du palonnier 1.The drive rod 5 is driven by the control rod 4 according to the invention by means of an adjusting device. This adjusting device comprises a first connecting rod 7 hingedly connected by one, said first 7a, of its ends, to the driving rod 5, and having at another said second end 7b, an axis 8 mounted in a light 9 provided at the so-called first end 10a of a second rod 10 whose second end 10b is hingedly connected to the control rod 4 belonging to the mechanism, this second connecting rod being mounted freely rotatable, between these two ends 10a, 10b, around the operating shaft 3 of the spreader 1. The displacement of the axis 8 in the slot 9 is able to cause the rotational movement of the first connecting rod 7, and therefore the driving rod 5 of the operating shaft 3, by means of teeth 11 provided on the one hand, on the driving rod 5, and on the other hand, on the operating shaft 3, which causes a change in the rotational position of the rudder 1.

Cette bielle d'entraînement 5 est une bielle double comportant deux parties 5a,5b en regard reliées par pliage par l'une de leurs extrémités, ces deux parties étant placées respectivement de part et d'autre de la première 7 et de la seconde bielle 10 et étant traversées par l'arbre de manoeuvre 3.This drive rod 5 is a double rod having two parts 5a, 5b opposite connected by folding by one of their ends, these two parts being placed respectively on either side of the first 7 and the second connecting rod. 10 and being traversed by the operating shaft 3.

Ce dispositif de réglage comporte également un dispositif destiné à comprimer la première bielle 7 au niveau de l'articulation 7b contre la seconde bielle 10, en ramenant les deux parties 10c, 10d de la bielle de commande 10 l'une en direction de l'autre.This adjusting device also comprises a device for compressing the first connecting rod 7 at the articulation 7b against the second connecting rod 10, by bringing the two parts 10c, 10d of the control rod 10 back towards one another. other.

Ce système de compression comporte une vis 12 vissée dans l'axe 8 formant écrou. Le vissage de la vis 12 dans l'axe 8 comprime entre elles les bielles 10c, 10d et 7 jusqu'à l'obtention d'un serrage suffisant pour maintenir une position relative entre la première bielle 7 et la seconde bielle 10, et ainsi empêcher la modification de cette position relative.This compression system comprises a screw 12 screwed into the shaft 8 forming a nut. The screwing of the screw 12 in the axis 8 compresses the rods 10c, 10d and 7 together until a sufficient clamping is obtained to maintain a relative position between the first rod 7 and the second rod 10, and thus prevent the modification of this relative position.

Le fonctionnement d'un appareil de protection électrique selon une réalisation particulière de l'invention va être décrit dans ce qui suit en référence aux figures 4 et 5.The operation of an electrical protection device according to a particular embodiment of the invention will be described in the following with reference to Figures 4 and 5 .

Tout d'abord, le palonnier 1 est amené dans une position dite de ligne dans laquelle le contact mobile 2 est en contact électrique avec le contact fixe 6, par l'intermédiaire du mécanisme d'ouverture/fermeture comportant la bielle de commande 4. Puis, lorsque les deux contacts 2,6 sont fermés, on effectue un réglage plus précis de la position relative des deux contacts en déplaçant en translation l'axe 8 dans la lumière 9 en direction d'une extrémité ou de l'autre de la lumière, et donc en entraînant la première bielle 7 en rotation dans le sens anti-horaire ou horaire selon que l'on veut déplacer la bielle d'entraînement 5 de l'arbre de manoeuvre 3 respectivement dans le sens horaire ou dans le sens anti-horaire. Sur la figure 4, l'axe 8 associé à la première bielle 7 est situé à l'une des extrémités de la lumière 9, l'extrémité située le plus loin de l'arbre de manoeuvre 3. Dans cette position, l'angle entre la bielle d'entraînement 5 et la seconde bielle 10 est minimum, ce qui correspond à une valeur de déplacement minimale de la bielle d'entraînement 5 et donc de l'arbre de manoeuvre 3 dans le sens anti-horaire.First, the lifter 1 is brought into a so-called line position in which the movable contact 2 is in electrical contact with the fixed contact 6, via the opening / closing mechanism comprising the control rod 4. Then, when the two contacts 2.6 are closed, a more precise adjustment is made of the relative position of the two contacts by translating the axis 8 into the light 9 in the direction of one end or the other of the light, and thus driving the first rod 7 in rotation in the counter-clockwise or hourwise direction as one wants to move the drive rod 5 of the operating shaft 3 respectively clockwise or anti-clockwise -Schedule. On the figure 4 the axis 8 associated with the first link 7 is located at one end of the slot 9, the end farthest from the operating shaft 3. In this position, the angle between the connecting rod 5 drive and the second rod 10 is minimum, which corresponds to a minimum displacement value of the drive rod 5 and therefore of the operating shaft 3 in the counterclockwise direction.

Sur la figure 5, l'axe 8 a été déplacé vers l'autre extrémité de la lumière 9, ce qui correspond à une valeur maximale de l'angle entre la bielle d'entraînement 5 et la seconde bielle 10, et donc à un déplacement maximal en rotation de l'arbre de manoeuvre 3 dans le sens horaire.On the figure 5 , the axis 8 has been moved towards the other end of the slot 9, which corresponds to a maximum value of the angle between the driving rod 5 and the second connecting rod 10, and therefore to a maximum displacement in rotation of the operating shaft 3 clockwise.

Après ce réglage, le maintien en position du palonnier 1 est réalisé par serrage de la vis 12 dans l'axe 8 de manière à rapprocher les deux parties de la bielle 10 l'une vers l'autre, et donc obtenir la compression de la première bielle 7 sur la seconde bielle 10 et le blocage en position de l'axe 8 dans la lumière 9.After this adjustment, the holding in position of the spreader 1 is achieved by tightening the screw 12 in the axis 8 so as to bring the two parts of the rod 10 towards each other, and thus obtain the compression of the first rod 7 on the second rod 10 and the locking in position of the axis 8 in the light 9.

Ainsi, grâce à l'invention, les efforts nécessaires lors des manoeuvres de réglage, c'est-à-dire le couple exercé au niveau du palonnier 1, lesquels sont transmis au niveau du maintien du réglage, s'exercent sensiblement perpendiculairement à la lumière de réglage 9. Il y a donc une sollicitation extrêmement faible en glissement dans la lumière 9. Ainsi, après serrage du système, le déréglage par glissement dans la lumière 9 est impossible.Thus, thanks to the invention, the forces required during the adjustment maneuvers, that is to say the torque exerted at the level of the rudder 1, which are transmitted at the level of maintaining the adjustment, are exerted substantially perpendicular to the Adjusting light 9. There is therefore an extremely low sliding load in the lumen 9. Thus, after tightening the system, the sliding adjustment in the lumen 9 is impossible.

L'invention propose donc un dispositif de réglage du palonnier 1 de conception simple permettant de réduire la dispersion des couteaux du ou des palonniers dans le cas d'un appareil multipolaire, dans la position ligne fermée.The invention therefore proposes a device for adjusting the rudder 1 of simple design to reduce the dispersion of the blades or pedals in the case of a multipolar device in the closed line position.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple.Of course, the invention is not limited to the embodiments described and illustrated which have been given by way of example.

Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont réalisées suivant son esprit.On the contrary, the invention comprises all the technical equivalents of the means described and their combinations if they are carried out according to its spirit.
