Ces accrochages 9,10 sont amenés à être désactivés par l'actionnement soit des boutons d'ouverture 5 ou de fermeture 6, ou bien des bobines d'ouverture 7 ou de fermeture 8, dont les éléments d'actionnement 17,18,19,20 sont aptes à agir sur les demi-lunes correspondantes, soit directement pour ce qui concerne l'accrochage d'ouverture 10, soit par l'intermédiaire d'une liaison mécanique L pour ce qui concerne l'accrochage de fermeture 9, de manière à désactiver l'accrochage correspondant et ainsi entraîner soit l'ouverture soit la fermeture des contacts mobiles de l'ampoule, par l'intermédiaire des ressorts d'ouverture ou de fermeture associés aux demi-lunes précités 15,12.These clashes 9, 10 are made to be deactivated by the actuation of either the opening or closing buttons 6, or the opening or closing coils 8, whose actuating elements 17, 18, 19 , 20 are able to act on the corresponding half-moons, either directly with regard to the opening catch 10 or via a mechanical connection L with regard to the closing catch 9, so as to deactivate the corresponding catch and thus cause either opening or closing of the movable contacts of the bulb, via the opening or closing springs associated with the aforementioned half-moons 15,12.

Pour ce qui concerne le dispositif d'accrochage de fermeture 9 seulement, la cellule C comporte également un ressort dit d'énergie de fermeture 23 apte à coopérer avec le dispositif d'accrochage de fermeture 9 de manière lors du déverrouillage de ce dernier, à augmenter la vitesse de fermeture des contacts de l'ampoule lors du déverrouillage de l'accrochage.With regard to the closing fastening device 9 only, the cell C also comprises a closing energy spring 23 adapted to cooperate with the closing fastening device 9 so as to unlock the latter, to increase the closing speed of the contacts of the bulb when unlocking the hanging.

Cette liaison mécanique L illustrée sur les figures 5 à 8, comporte un support de glissière 24 à l'intérieur duquel est montée à coulissement une glissière 25, ledit support et la glissière étant traversés par la demi-lune de fermeture 12, laquelle est fixée par encastrement par sa partie d'extrémité libre 26 sur le support de glissière 24 comportant une ouverture de forme correspondante pour le passage de cette partie d'extrémité.This mechanical connection L illustrated on the Figures 5 to 8 , comprises a slide support 24 inside which is slidably mounted a slide 25, said support and the slide being traversed by the closing half-moon 12, which is fixed by embedding by its free end portion 26 on the slide support 24 having a correspondingly shaped opening for the passage of this end portion.

Cette glissière 25 comporte deux ouvertures allongées 27,28 (figures 7 et 8) séparées par une cloison 29, l'une 28 des ouvertures 27,28 étant destinée à être traversée par la partie d'extrémité précitée 26 de la demi-lune 12 et à loger un ressort 30 interposé entre un méplat 31 appartenant à cette partie d'extrémité et la face intérieure 33, en regard dudit méplat, appartenant à la glissière, tandis que la face 32 de cette partie d'extrémité 26 de demi-lune, opposée à celle comportant le méplat 31, est en appui contre la cloison précitée 29 de la glissière 25.This slide 25 has two elongate openings 27,28 ( figures 7 and 8 ) separated by a partition 29, one 28 of the openings 27,28 being intended to be traversed by the aforementioned end portion 26 of the half-moon 12 and to accommodate a spring 30 interposed between a flat portion 31 belonging to this part end and the inner face 33, opposite said flat, belonging to the slide, while the face 32 of this end portion 26 of half-moon, opposite that having the flat portion 31, bears against the partition aforementioned 29 of the slide 25.

Cette glissière 25 est rappelée en position déployée illustrée sur la figure 5 au moyen du ressort précité 30, le déplacement de la glissière 25 vers sa position escamotée illustrée sur la figure 6 étant obtenu par l'actionnement d'une partie de manoeuvre 34 de la glissière 25 formant plot coopérant avec des moyens de renvoi R tels que ceux-ci seront décrits dans ce qui suit.This slide 25 is recalled in the extended position illustrated on the figure 5 by means of the aforementioned spring 30, the displacement of the slide 25 towards its retracted position illustrated on the figure 6 being obtained by the actuation of an operating portion 34 of the slide 25 forming a stud cooperating with return means R such that they will be described in the following.

Sur ces figures 5 à 8, on voit également une pièce montée autour de l'arbre de la demi-lune, et apte à tourner librement autour de l'axe de la demi-lune, cette pièce étant la palette 35 d'une bobine de fermeture 8.On these Figures 5 to 8 a piece mounted around the half-moon shaft and able to rotate freely about the axis of the half moon, this part being the pallet 35 of a closing coil 8.

Cette palette 35 comporte une partie en saillie 36 apte à coopérer avec une partie en saillie 37 appartenant à la glissière 25, ces deux parties s'étendant sensiblement parallèlement à l'axe de la demi-lune, de telle manière que lorsque la glissière est en position déployée, la palette 35 est apte à entraîner la demi-lune 12 en rotation lors de l'actionnement de la bobine 8, alors que lorsque la glissière 25 est escamotée, l'actionnement de la bobine n'a aucun effet sur la glissière 25 et donc sur la demi-lune 12.This pallet 35 has a projecting portion 36 adapted to cooperate with a projecting portion 37 belonging to the slide 25, these two parts extending substantially parallel to the axis of the half-moon, so that when the slide is in the deployed position, the pallet 35 is able to drive the half moon 12 in rotation during the actuation of the coil 8, whereas when the slide 25 is retracted, actuation of the coil has no effect on the slide 25 and thus on the half-moon 12.

Autour de l'arbre 2 d'entraînement des contacts de l'ampoule à vide du disjoncteur est montée une pièce rigide solidaire dudit arbre, appelée indicateur de position 38. Cet indicateur coopère avec l'une 41 des parties d'extrémités 41,42 dite première d'un levier coudé de renvoi 39 dit renvoi de l'indicateur, monté articulé autour d'un axe fixe du support de l'appareillage, tel qu'illustré sur les figures 16a et 16b. Autour d'un second axe du support est également monté articulé un second levier de renvoi 40, dit renvoi de glissière, comportant une première partie 43 destinée à coopérer avec la seconde partie d'extrémité 42 du renvoi 39 de l'indicateur, et une seconde partie 44, destinée à coopérer avec la glissière 25, de la manière qui sera décrite dans ce qui suit.Around the drive shaft 2 of the contacts of the vacuum interrupter of the circuit breaker is mounted a rigid part integral with said shaft, called the position indicator 38. This indicator cooperates with one of the 41 end portions 41, 42 said first of an angled return lever 39 said reference of the indicator, mounted hinged about a fixed axis of the support of the apparatus, as illustrated on the Figures 16a and 16b . Around a second axis of the support is also mounted articulated a second return lever 40, said slide return, having a first portion 43 intended to cooperate with the second end portion 42 of the reference 39 of the indicator, and a second portion 44, intended to cooperate with the slide 25, as will be described in the following.

Sur les figures 16a et 16b, on voit que le premier levier 39 est apte à entraîner le second levier 40 dans un sens ou dans l'autre par l'intermédiaire de deux plots 54,55 situés sur la face arrière de la première partie 43 du second levier 40 coopérant avec la seconde partie 42 du premier levier 39.On the Figures 16a and 16b it can be seen that the first lever 39 is capable of driving the second lever 40 in one direction or the other via two studs 54, 55 located on the rear face of the first part 43 of the second lever 40 cooperating with the second portion 42 of the first lever 39.

Comme déjà indiqué précédemment, cette cellule C comporte également un interrupteur de mise à la terre en série avec le disjoncteur précité, ledit interrupteur comportant un arbre de manoeuvre 4 de l'arbre de mise à la terre 3 manoeuvrable au moyen d'un levier à travers un orifice prévu à cet effet, après l'actionnement d'un sélecteur S de choix. L'actionnement de ce sélecteur S a pour effet de libérer ou d'obturer l'orifice d'accès audit arbre de mise à la terre 3 au moyen d'un levier 51, dit second levier d'inter verrouillage comportant un volet d'obturation 53.As already indicated above, this cell C also comprises a grounding switch in series with the above-mentioned circuit breaker, said switch comprising an operating shaft 4 of the grounding shaft 3 which can be operated by means of a control lever. through a hole provided for this purpose, after the actuation of a selector S of choice. The actuation of this selector S has the effect of releasing or closing the access port to said grounding shaft 3 by means of a lever 51, said second interlocking lever having a flap of shutting 53.

Le disjoncteur et l'interrupteur de mise à la terre sont reliés mécaniquement par un dispositif d'inter verrouillage I, plus particulièrement illustré sur la figure 16 et permettant d'empêcher l'actionnement du sélecteur S de la mise à la terre de la cellule lorsque le disjoncteur est en position fermé, d'empêcher l'accès à l'arbre de commande 1 du disjoncteur lorsque le sélecteur S est en position terre, l'orifice d'introduction du levier de manoeuvre de l'arbre de mise à la terre 3 étant libéré, et d'empêcher la fermeture du disjoncteur lors d'une intention de mise à la terre, le sélecteur S étant en position de mise à la terre.The circuit breaker and the grounding switch are mechanically connected by an interlocking device I, more particularly illustrated in FIG. figure 16 and to prevent the actuation of the selector S from the earthing of the cell when the circuit-breaker is in the closed position, to prevent access to the control shaft 1 of the circuit-breaker when the selector S is in position earth, the opening of the operating lever of the earth shaft 3 being released, and to prevent the closure of the circuit breaker during an intention to ground, the selector S being in position grounding.

A cet effet, le dispositif d'inter verrouillage I comporte un premier levier d'inter verrouillage 45 monté articulé autour de l'arbre de manoeuvre 2 des contacts de l'ampoule du disjoncteur, ledit levier 45 comportant un premier bras 46 comportant un volet 47 apte à obturer l'orifice de manoeuvre du disjoncteur, ledit premier levier 45 étant relié de manière articulé par l'intermédiaire d'un second bras 48 à l'une des extrémités d'une bielle 49 dont l'autre extrémité est reliée de manière articulée à l'une des extrémités d'un bras dit premier 50 appartenant à un second levier d'inter verrouillage 51 monté articulé autour d'un axe fixe de la cellule et comportant un second bras 52 dont l'extrémité libre comporte un volet 53 d'obturation de l'orifice d'accès à l'arbre de mise à la terre 3.For this purpose, the interlocking device I comprises a first interlocking lever 45 mounted hinged around the operating shaft 2 of the contacts of the circuit-breaker lamp, said lever 45 comprising a first arm 46 comprising a shutter 47 adapted to close the opening of operation of the circuit breaker, said first lever 45 being connected in an articulated manner via a second arm 48 at one end of a connecting rod 49 whose other end is connected by articulated manner at one of the ends of a so-called first arm 50 belonging to a second interlocking lever 51 mounted articulated around a fixed axis of the cell and having a second arm 52 whose free end comprises a flap 53 shutting off the access hole to the grounding shaft 3.

L'axe d'articulation entre la bielle 49 et le second levier d'inter verrouillage 51 se prolonge par un plot 56 destiné à être introduit dans une lumière 57 du sélecteur S, lequel est monté coulissant par rapport à un support fixe de la cellule entre une position dans laquelle la mise à la terre est autorisée et une position dans laquelle la mise à la terre est interdite, ledit sélecteur S pouvant être entraîné entre ces deux positions au moyen d'un organe de manoeuvre 58 située sur sa face extérieure.The axis of articulation between the connecting rod 49 and the second interlock lever 51 is extended by a stud 56 intended to be introduced into a slot 57 of the selector S, which is slidably mounted relative to a fixed support of the cell between a position in which the earthing is allowed and a position in which the earthing is prohibited, said selector S can be driven between these two positions by means of an operating member 58 located on its outer face.

Ce dispositif d'inter verrouillage I comporte également une serrure 59 comportant une came 60 apte à coopérer avec une pièce formant renvoi 61 solidaire du premier levier d'inter verrouillage précité 45, ladite serrure 59 étant apte à entraîner ledit levier 45 dans la position d'obturation de l'orifice de manoeuvre de l'arbre de manoeuvre 1 de la commande du disjoncteur.This interlocking device I also comprises a lock 59 comprising a cam 60 adapted to cooperate with a return part 61 integral with the aforementioned first interlocking lever 45, said lock 59 being able to drive said lever 45 into the position d closing the maneuvering orifice of the operating shaft 1 of the circuit breaker control.

Cette pièce formant renvoi 61 est également destinée à coopérer avec un plot 62 solidaire du renvoi de glissière 40, de manière à entraîner la glissière 25 dans une position escamotée dans le support, lorsque le sélecteur S est amené en position de mise à la terre et d'obturation de l'orifice d'accès à l'arbre de commande 1.This return part 61 is also intended to cooperate with a stud 62 integral with the slideway 40, so as to drive the slideway 25 into a groove. position retracted into the support, when the selector S is brought into the grounding and shutter position of the access port to the control shaft 1.

Ce dispositif d'inter verrouillage I comporte également un plot 63 solidaire de l'indicateur de position précité 38 et apte à coopérer avec le premier levier d'inter verrouillage 45 de manière à empêcher la manoeuvre du sélecteur S vers la position de mise à la terre lorsque le disjoncteur est en position fermée.This interlock device I also comprises a stud 63 integral with the above-mentioned position indicator 38 and adapted to cooperate with the first interlocking lever 45 so as to prevent the selector S from being operated to the setting position. ground when the circuit breaker is in the closed position.

Le fonctionnement de la cellule selon l'invention va être décrit dans ce qui suit en référence aux figures.The operation of the cell according to the invention will be described in the following with reference to the figures.

Sur la figure 9, le disjoncteur est dans une position ouverte prêt à fermer, une certaine quantité d'énergie accumulée étant stockée dans le ressort de fermeture autour de l'axe de la demi-lune 12. Dans cette position, le ressort 30 situé à l'intérieur de la glissière 25 a rappelé la glissière dans une position déployée dans laquelle ladite glissière 25 est située en regard de l'élément d'actionnement 18 du bouton de fermeture 6 de manière à pouvoir coopérer avec celui-ci lorsque celui-ci sera actionné.On the figure 9 , the circuit breaker is in an open position ready to close, a certain amount of accumulated energy being stored in the closing spring around the axis of the half-moon 12. In this position, the spring 30 located inside of the slide 25 has recalled the slide in an extended position in which said slide 25 is located opposite the actuating element 18 of the closure button 6 so as to cooperate with it when it is actuated.

De la même manière sur la figure 10, la palette 35 de la bobine 8 se trouve dans une position illustrée sur la figure 5 dans laquelle elle est prête à entraîner la demi-lune de fermeture 12, dés que la bobine sera actionnée. Sur ces deux figures, l'orifice d'accès à l'arbre de commande du disjoncteur 1 est libéré tandis que l'orifice d'accès à l'arbre de mise à la terre 3 est obturé.In the same way on the figure 10 the pallet 35 of the spool 8 is in a position illustrated on the figure 5 in which it is ready to drive the closing half-moon 12, as soon as the coil is actuated. In these two figures, the access opening to the control shaft of the circuit breaker 1 is released while the access port to the grounding shaft 3 is closed.

Lorsque soit le bouton de fermeture 6, soit la bobine de fermeture 8 est actionnée, l'élément d'actionnement 18,20 de cet élément entraîne en rotation la glissière 25 soit directement pour le bouton, soit par l'intermédiaire de la palette 35 pour ce qui concerne la bobine, et donc la demi-lune de fermeture 12, ce qui provoque le déverrouillage de l'accrochage de fermeture 9 et donc la fermeture des contacts de l'ampoule à vide, position illustrée sur les figures 11, 12 et 13.When either the closing button 6 or the closing coil 8 is actuated, the actuating element 18,20 of this element rotates the slide 25 either directly for the button or via the pallet 35. as regards the coil, and therefore the closing half-moon 12, which causes the unlocking of the closing fastener 9 and thus the closing of the contacts of the vacuum interrupter, as illustrated on the figures 11 , 12 and 13 .

Lors du passage de la cellule C de la position ouverte à la position fermée, la rotation de l'arbre 2 de manoeuvre des ampoules qui en résulte dans le sens antihoraire, entraîne l'indicateur de position 38 en rotation, lequel entraîne dans son mouvement le premier levier de renvoi 39 dans le sens horaire et le second levier de renvoi 40 dans le sens antihoraire, ceci ayant pour effet d'entraîner la glissière 25 jusqu'à une position escamotée de celle-ci, position illustrée sur les figures 11, 12 et 13.During the passage of the cell C from the open position to the closed position, the rotation of the shaft 2 of operating the bulbs which results in the counterclockwise direction, causes the position indicator 38 in rotation, which causes in its movement the first deflection lever 39 in the clockwise direction and the second deflection lever 40 in the counterclockwise direction, this having the effect of driving the slide 25 to a retracted position thereof, a position illustrated in FIGS. figures 11 , 12 and 13 .

Dans cette position, une nouvelle action sur le bouton de fermeture 6 ou un nouvel actionnement de la bobine de fermeture 8, sont sans effet sur la glissière 25 car celle-ci est escamotée. D'autre part, le déplacement du sélecteur S vers une position autorisant la manoeuvre de l'arbre de mise à la terre 3 est empêché par l'amenée en butée du levier d'inter verrouillage dit premier 45 avec le plot 63 présent sur l'indicateur de position 38.In this position, a new action on the closing button 6 or a new actuation of the closing coil 8, have no effect on the slide 25 because it is retracted. On the other hand, the displacement of the selector S to a position allowing the operation of the grounding shaft 3 is prevented by bringing into abutment the first interlocking lever 45 with the stud 63 present on the ground. position indicator 38.

Dans cette position, l'accès à l'arbre de manoeuvre 1 de la commande est autorisé pour accumuler de l'énergie dans la commande, tandis que l'accès à l'arbre de mise à la terre 3 est empêché.In this position, access to the operating shaft 1 of the control is allowed to accumulate energy in the control, while access to the grounding shaft 3 is prevented.

A partir d'une position fermée telle qu'illustrée sur les figures 11,12 et 13, et après un ordre d'ouverture non maintenu, l'élément d'actionnement 17 du bouton d'ouverture 5 ou de la bobine d'ouverture 7 entraîne le déverrouillage de l'accrochage d'ouverture 10, puis une action sur le renvoi 15a de la demi-lune d'ouverture 15, ce qui a pour conséquence d'entraîner le renvoi de glissière 40 dans le sens antihoraire entraînant la glissière 25 dans une position escamotée, après quoi, si l'ordre d'ouverture n'est pas maintenu, la glissière est rappelée par le ressort 30 dans une position déployée autorisant une fermeture.From a closed position as illustrated on figures 11 , 12 and 13 , and after an unmaintained opening command, the actuating element 17 of the opening button 5 or of the opening spool 7 causes the opening catch 10 to be unlocked and then an action on the return 15a of the opening half-moon 15, which has the effect of causing the slider 40 to return in the counterclockwise direction causing the slider 25 to be in a retracted position, after which, if the opening order is not not maintained, the slide is returned by the spring 30 in an extended position allowing a closure.

Cependant, lorsque l'ordre d'ouverture est maintenu par le bouton d'ouverture 5 tel qu'illustré sur la figure 14, ou par la bobine d'ouverture 7 tel qu'illustré sur la figure 15, la glissière 25 est maintenue par le renvoi de glissière 40 entraîné par le renvoi de demi-lune d'ouverture 15a, dans sa position escamotée, empêchant toute action de fermeture.However, when the opening order is maintained by the opening button 5 as illustrated on the figure 14 , or by the opening coil 7 as illustrated on the figure 15 , the slide 25 is held by the slide return 40 driven by the half-moon aperture 15a, in its retracted position, preventing any closing action.

Sur la figure 17, le disjoncteur est dans une position prête à fermer, une certaine quantité d'énergie ayant été accumulée pour la fermeture des contacts de l'ampoule par le ressort de fermeture 23. Le sélecteur S a été déplacé vers la droite de la cellule C signalant une intention de mise à la terre de la cellule. Ce déplacement a entraîné d'une part, le déplacement dans le sens horaire du premier levier d'inter verrouillage 45 entraînant l'obturation de l'orifice d'introduction du levier de manoeuvre 1 de la commande du disjoncteur et d'autre part, le déplacement dans le sens antihoraire du second levier d'inter verrouillage 51 de manière à libérer l'orifice d'accès à l'arbre de mise à la terre 3. Le premier levier d'inter verrouillage 45 a manoeuvré le renvoi de glissière 40 de sorte que la liaison entre la glissière 25 et le bouton de fermeture 6 ou la bobine de fermeture 8 est devenue impossible.On the figure 17 , the circuit breaker is in a ready-to-close position, a certain amount of energy having been accumulated for closing the contacts of the bulb by the closing spring 23. The selector S has been moved to the right of the cell C signaling an intention to ground the cell. This movement has caused on the one hand, the movement in the clockwise direction of the first interlocking lever 45 causing the closing of the insertion opening of the operating lever 1 of the control of the circuit breaker and on the other hand, the counterclockwise movement of the second interlocking lever 51 so as to release the access port to the grounding shaft 3. The first interlocking lever 45 has operated the slide return 40 so that the connection between the slide 25 and the closure button 6 or the closing coil 8 has become impossible.

Sur la figure 18, le disjoncteur est dans une position prête à fermer, l'énergie de fermeture ayant été accumulée dans le ressort de fermeture. La mise à la terre est effective, l'arbre 3 de commande de la mise à la terre ayant été entraîné en rotation. Une butée 53a est prévue sur le volet d'obturation 53 du second levier d'inter verrouillage 51 pour maintenir la position de l'arbre 3 de mise à la terre et l'empêcher de tourner en sens inverse après la mise à la terre.On the figure 18 the circuit breaker is in a ready-to-close position, the closing energy having been accumulated in the closing spring. The grounding is effective, the earth control shaft 3 having been rotated. A stop 53a is provided on the shutter 53 of the second interlock lever 51 to maintain the position of the earth shaft 3 and prevent it from rotating in the opposite direction after grounding.

Sur la figure 19, on a utilisé une serrure 59 dite de verrouillage destinée à bloquer l'accès à l'arbre 1 de manoeuvre de la commande. Ainsi, grâce à une clé, la came 60 de la serrure 59 a été entraînée de 90 ° dans le sens antihoraire, ce qui a permis d'entraîner le renvoi 61 du premier levier d'inter verrouillage 45 dans le sens horaire, de manière d'une part, à empêcher l'accès à l'orifice de manoeuvre de l'arbre de commande 1 et d'autre part, à entraîner le sélecteur S dans une position d'intention de mise à la terre, et de maintenir cette position des leviers d'inter verrouillage 45,51, tant qu'une manoeuvre inverse de la clé n'a pas été réalisée. On notera que la clé de manoeuvre de la serrure 59 ne pourra être retirée de la serrure qu'après une rotation complète de 90°.

  • Les figures 20,21 et 22 illustrent trois réalisations possibles des boutons d'ouverture 5 et de fermeture 7 pouvant être utilisés.
  • La figure 20 illustre deux boutons rotatifs 64,65 d'actionnement respectivement d'ouverture et de fermeture. Ces deux boutons sont actionnés selon deux sens de rotation différents, par exemple dans le sens antihoraire pour réaliser l'ouverture et dans le sens antihoraire pour réaliser la fermeture.
On the figure 19 a so-called locking lock 59 has been used to block access to the operating shaft 1 of the control. Thus, thanks to a key, the cam 60 of the lock 59 has been driven 90 ° counterclockwise, which made it possible to drive the return 61 of the first interlocking lever 45 clockwise, so as to on the one hand, to prevent access to the maneuvering orifice of the control shaft 1 and, on the other hand, to drive the selector S to a position of intention of earthing, and to maintain this position of the interlocking levers 45,51, as long as a reverse operation of the key has not been performed. Note that the operating key of the lock 59 can be removed from the lock after a complete rotation of 90 °.
  • The figures 20 , 21 and 22 illustrate three possible embodiments of the opening and closing buttons 7 that can be used.
  • The figure 20 illustrates two rotary buttons 64,65 respectively opening and closing operation. These two buttons are operated in two different directions of rotation, for example in the counterclockwise direction to achieve the opening and counterclockwise to achieve the closure.

Ce mouvement de rotation de chacun des boutons est transformé en un mouvement de rotation des éléments d'actionnement 66,67.This rotational movement of each of the buttons is transformed into a rotational movement of the actuating elements 66, 67.

Sur la figure 21, un seul 68 des boutons est utilisé pour réaliser l'ouverture lorsque celui-ci est entraîné dans le sens antihoraire, et pour réaliser la fermeture lorsque celui-ci est entraîné dans le sens horaire. Dans ce cas, le mouvement en rotation du bouton est transformé en un mouvement en rotation des deux éléments d'actionnement correspondants 69,70, aptes à entraîner le déplacement de la demi-lune d'ouverture pour l'un ou la glissière pour l'autre.On the figure 21 only one of the buttons 68 is used to make the opening when it is driven counterclockwise, and to perform the closing when the latter is driven clockwise. In this case, the rotational movement of the button is converted into a rotational movement of the two corresponding actuating elements 69,70, able to cause the displacement of the opening half-moon for one or the slide for 'other.

Sur la figure 22, les deux boutons sont des boutons d'actionnement par pression 71,72, l'actionnement de l'un ou de l'autre des boutons entraînant le déplacement respectivement de deux éléments d'actionnement différents 73,74, se déplaçant en translation pour déplacer le renvoi de la demi-lune et la glissière.On the figure 22 , the two buttons are pressing buttons 71,72, the actuation of one or the other of the buttons causing the displacement respectively of two different actuating elements 73,74, moving in translation for move the return of the half moon and the slide.

On a donc réalisé selon l'invention un dispositif d'inter verrouillage pouvant être utilisé avantageusement dans une cellule électrique moyenne tension comportant un disjoncteur ou un interrupteur seul, ou bien dans une cellule comportant un disjoncteur ou interrupteur en série avec un sectionneur de terre.Thus, according to the invention, an interlocking device can be advantageously used in a medium-voltage electrical cell comprising a circuit breaker or a switch alone, or in a cell comprising a circuit breaker or switch in series with an earthing switch.

Dans le premier cas, le dispositif selon l'invention permet d'interdire de donner un ordre de fermeture si le produit est déjà fermé, si un ordre d'ouverture maintenu a été donné soit par le bouton d'ouverture, soit par la bobine.In the first case, the device according to the invention makes it possible to prohibit giving a closing order if the product is already closed, if a maintained opening order has been given either by the opening button or by the reel. .

Dans le second cas, le dispositif selon l'invention permet d'interdire de donner un ordre de fermeture, en plus des situations précédemment mentionnées, dans le cas où le sélecteur de choix de manoeuvre est en position terre, si le dispositif de commande est mis à la terre, ou bien si l'accès à l'arbre de commande est verrouillé au moyen d'une clé.In the second case, the device according to the invention makes it possible to prohibit giving a closing command, in addition to the situations mentioned above, in the case where the selector of choice of operation is in the earth position, if the control device is grounded, or if access to the drive shaft is locked by means of a key.

Ce dispositif est placé avantageusement en face avant, et permet de faire varier le type de bouton des commandes manuelles locales.This device is placed advantageously on the front face, and allows to vary the type of button local manual controls.

Cette solution permet de coupler les moyens d'inter verrouillage nécessaires au bon fonctionnement du disjoncteur ou interrupteur avec les moyens d'inter verrouillage nécessaires à l'association du disjoncteur ou interrupteur avec le sectionneur de terre, de manière à un réaliser un seul dispositif d'inter verrouillage de conception particulièrement simple.This solution makes it possible to couple interlocking means necessary for the proper operation of the circuit breaker or switch with the interlocking means necessary for the combination of the circuit breaker or switch with the earthing switch, so as to realize a single device of interlocking design particularly simple.

Ce dispositif permet de passer à la terre même si une énergie est déjà accumulée dans la commande pour la fermeture, ceci évite de faire une fermeture, puis une ouverture.This device allows to go to earth even if energy is already accumulated in the command for closing, this avoids closing and then opening.

Le système de verrouillage par clé entraîne le premier levier d'inter verrouillage, lequel manoeuvre le renvoi de glissière et la glissière. Ce système de verrouillage par clé interdit une fermeture même si l'énergie de fermeture est déjà accumulée dans le disjoncteur.The key lock system drives the first interlocking lever, which operates the slide return and slide. This key locking system prohibits closing even if the closing energy is already accumulated in the circuit breaker.
