Description

L'invention concerne une commande de sectionneur à trois positions de commutation incluant une position de fermeture, une position d'ouverture et une position de mise à la terre, par l'intermédiaire de laquelle le sectionneur peut être électriquement ou manuellement actionné. Elle comporte un arbre rotatif principal destiné à être accouplé au contact mobile du sectionneur. Cet arbre principal est mis en rotation lors des commutations, soit par un moteur électrique, lorsque ce moteur est alimenté de manière appropriée, soit manuellement par l'intermédiaire d'une manivelle, qui est alors accouplée avec un organe de commutation manuelle lié en mouvement avec l'arbre principal.The invention relates to a disconnector control with three positions of switching including a closed position, an open position and a grounding position, through which the disconnector can be electrically or manually operated. It has a tree main rotary intended to be coupled to the movable contact of the disconnector. This main shaft is rotated during switching, either by a electric motor, when this motor is adequately powered, either manually via a crank, which is then coupled with a manual switching member linked in movement with the main tree.

L'invention concerne plus particulièrement une commande pour un sectionneur haute tension (72,5 à 145 kVolts) de poste blindé.The invention relates more particularly to an order for a high voltage disconnector (72.5 to 145 kVolts) of shielded substation.

Les utilisateurs d'une telle commande ont généralement des exigences de sécurité différentes quant aux séquences de commutation manuelle que l'opérateur est autorisé à effectuer, ces séquences de commutation définissant une certaine logique d'interverrouillage pour la commande. Par exemple, un utilisateur peut exiger que la commande permette d'interdire une commutation manuelle du sectionneur vers sa position de mise à la terre si le sectionneur n'est pas dans une position d'ouverture ou encore d'interdire une commutation manuelle du sectionneur vers sa position de fermeture quand le sectionneur est dans une position de mise à la terre. Il est possible de concevoir une commande de sectionneur dans laquelle est intégré un mécanisme interdisant certaines séquences de commutation manuelle du sectionneur pour satisfaire des exigences particulières d'un utilisateur. Toutefois, les utilisateurs de telles commandes de sectionneur à trois positions de commutation sont souvent amenés à changer la logique d'interverrouillage des commandes de sectionneur. Suivant la complexité de ce mécanisme, le changement de logique d'interverrouillage dans une commande peut être une opération longue et coûteuse. Une commande de sectionneur à trois positions de commutation pouvant être facilement modifiée pour mettre en oeuvre différentes logiques d'interverrouillage est donc recherchée.The users of such an order generally have requirements security settings for manual switching sequences the operator is authorized to perform these switching sequences defining a certain interlocking logic for the command. Through example, a user may require the command to prohibit manual switching of the disconnector to its earthing position if the disconnector is not in the open position or prohibit manual switching of the disconnector to its position closing when the disconnector is in a grounding position. he it is possible to design a disconnector control in which is integrated a mechanism prohibiting certain switching sequences manual disconnector to meet specific requirements of a user. However, users of such disconnector commands to three switching positions are often required to change the logic of the switch disconnector controls. Depending on the complexity of this mechanism, the change in interlocking logic in a ordering can be a long and costly operation. An order from disconnector with three switching positions which can be easily modified to implement different interlocking logic is therefore sought after.

Selon l'invention, il est proposé une commande de sectionneur à trois positions de commutation avec laquelle on change de logique d'interverrouillage en changeant une pièce dans laquelle la logique d'interverrouillage souhaitée est implantée, cette pièce étant montée amovible dans la commande.According to the invention, a three-way disconnector control is proposed. switching positions with which the logic is changed interlocking by changing a room in which the logic interlocking device is installed, this part being mounted removable in the control.

La commande de sectionneur qui est à trois positions de commutation incluant une position de fermeture, une position d'ouverture et une position de mise à la terre, comporte une entrée permettant le passage d'une manivelle pour commuter manuellement le sectionneur d'une position de commutation vers une autre.The disconnector control which has three switching positions including a closed position, an open position and a position earthing, has an entrance allowing the passage of a crank to manually switch the disconnector from a position switching to another.

Selon l'invention, cette commande comporte une seconde entrée de manivelle, la première entrée de manivelle étant disposée en regard d'un premier organe de commutation manuelle du sectionneur qui commute le sectionneur de sa position de fermeture vers sa position d'ouverture ou inversement, lorsqu'il est actionné à l'aide de la manivelle introduite par cette première entrée, la seconde entrée de manivelle étant disposée en regard d'un second organe de commutation manuelle du sectionneur qui commute le sectionneur de la position d'ouverture vers la position de mise à la terre ou inversement, lorsqu'il est actionné à l'aide de la manivelle introduite par la seconde entrée. Deux volets mobiles sont respectivement affectés chacun à une entrée différente de manivelle et sont associés chacun à un bras de verrouillage, chaque volet étant apte à être déplacé pour obturer ou libérer l'entrée de manivelle à laquelle il est affecté. La commande comporte en outre une pièce, notamment exploitée à des fins d'interverrouillage, qui est montée amovible sur un arbre rotatif lié en mouvement aux organes de commutation. Cette pièce comporte des pistes dans lesquelles les bras de verrouillage des volets sont respectivement assujettis, pour empêcher ou alternativement autoriser le déplacement de l'un ou l'autre des deux volets et donc l'insertion de la manivelle dans l'une ou l'autre des deux entrées de manivelle.According to the invention, this command comprises a second entry of crank, the first crank entry being arranged opposite a first manual switching device of the disconnector which switches the disconnector from its closed position to its open position or conversely, when it is actuated using the crank introduced by this first entry, the second crank entry being arranged opposite a second manual switching device of the disconnector which switches the disconnector from the open position to the earth position or conversely, when it is actuated using the crank introduced by the second entry. Two mobile shutters are each assigned to a different crank entry and are each associated with an arm of locking, each flap being able to be moved to close or release the crank input to which it is assigned. The order includes in addition to a room, in particular used for interlocking purposes, which is removable mounting on a rotating shaft linked in movement to the switching. This piece has tracks in which the arms of locking shutters are respectively secured, to prevent or alternatively authorize the displacement of one or other of the two components and so inserting the crank in one or the other of the two inputs of crank.

L'invention est décrite ci-après plus en détails et illustrée sur les dessins.The invention is described below in more detail and illustrated in the drawings.

La figure 1 est une vue schématique en perspective d'un exemple de réalisation d'une commande selon l'invention.Figure 1 is a schematic perspective view of an example of realization of an order according to the invention.

La figure 2 illustre la position d'une pièce rotative de blocage en butée contre la manivelle à la fin d'une commutation manuelle fermeture/ouverture du sectionneur.FIG. 2 illustrates the position of a rotary blocking piece in abutment against the crank at the end of a manual closing / opening switching of the disconnector.

La figure 3 illustre la position d'une pièce rotative de blocage en butée contre la manivelle à la fin d'une commutation manuelle mise à la terre/ouverture du sectionneur. FIG. 3 illustrates the position of a rotary blocking piece in abutment against the crank at the end of a manual switching set to earthing / disconnector opening.

Sur la figure 1, la commande d'un sectionneur à trois positions de commutation comprend un arbre principal de commande 1 monté rotatif et relié au contact mobile du sectionneur (non représenté sur la figure). Cet arbre principal 1 est entraíné en rotation par un moteur électrique 2 par l'intermédiaire d'un train d'engrenages 3, lorsque la commande du sectionneur est électriquement assurée. Le mouvement de rotation de l'arbre principal 1 est renvoyé par l'intermédiaire de pignons 4 sur un arbre secondaire rotatif 5 faisant face à une paroi frontale 6 d'un boítier dans lequel la commande est disposée. L'arbre secondaire 5 porte une pièce 7, servant notamment à des fins d'interverrouillage, qui est représentée ici sous la forme d'un disque. Cette pièce 7 est montée de manière amovible sur l'arbre secondaire 5 et, dans la réalisation présentée, elle est fixée à une extrémité libre de l'arbre 5.In FIG. 1, the control of a disconnector with three positions of switching includes a main control shaft 1 rotatably mounted and connected to the movable contact of the disconnector (not shown in the figure). This main shaft 1 is rotated by an electric motor 2 by via a gear train 3, when the control of the disconnector is electrically insured. The rotational movement of the shaft main 1 is returned via pinions 4 on a shaft secondary rotating 5 facing a front wall 6 of a housing in which the command is arranged. The secondary shaft 5 carries a part 7, used in particular for interlocking purposes, which is shown here under the shape of a disc. This part 7 is removably mounted on the secondary shaft 5 and, in the embodiment presented, it is fixed to a free end of shaft 5.

La paroi frontale 6 du boítier de la commande est munie de deux entrées de manivelle 8 et 9 distinctes. Ces deux entrées 8,9 de manivelle sont disposées respectivement en regard de deux organes de commutation manuelle 10,11 du sectionneur qui sont mécaniquement couplés dans le boítier de la commande et qui sont prévus pour être mis en rotation à l'aide d'une manivelle M. Dans la réalisation présentée, ces deux organes de commutation sont équipés chacun d'un carré sur lequel une douille d'entraínement, comportée par une manivelle M, peut être temporairement emmanchée. Ces deux carrés sont présentés avec des axes de rotation perpendiculairement orientés par rapport à la paroi frontale 6 et au plan du disque constituant la pièce 7. Plus particulièrement, ce disque est interposé entre les carrés des organes 10,11 et les entrées de manivelle 8, 9, parallèlement à la paroi frontale 6 et il balaye un plan que coupe la manivelle M, quand elle est emmanchée en prise avec l'un ou l'autre des carrés des organes 10,11. Dans la réalisation présentée, il est donc prévu une ouverture 26 permettant à une manivelle M de traverser le disque constituant la pièce 7, dans des conditions déterminées qui sont précisées par la suite.The front wall 6 of the control unit is provided with two inputs crank 8 and 9 separate. These two crank inputs 8.9 are arranged respectively opposite two switching members manual 10,11 of the disconnector which are mechanically coupled in the control box and which are intended to be rotated using of a crank M. In the embodiment presented, these two organs of switching are each equipped with a square on which a socket drive, with a crank M, can be temporarily fitted. These two squares are presented with axes of rotation perpendicularly oriented with respect to the front wall 6 and to the plane of the disc constituting part 7. More particularly, this disc is interposed between the squares of the organs 10, 11 and the crank inlets 8, 9, parallel to the front wall 6 and it scans a plane which the crank cuts M, when it is fitted in engagement with one or other of the squares of organs 10.11. In the embodiment presented, provision is therefore made for opening 26 allowing a crank M to pass through the constituent disc Exhibit 7, under specified conditions which are specified below.

Les organes de commutation 10,11 sont mécaniquement couplés par l'intermédiaire d'un dispositif de transmission où les mouvements de rotation appliqués à l'un sont transmis à l'autre, ainsi qu'aux deux arbres 1 et 5.The switching members 10,11 are mechanically coupled by via a transmission device where rotational movements applied to one are transmitted to the other, as well as to the two trees 1 and 5.

Dans la réalisation présentée, chacun des organes 10,11 est solidaire d'une poulie 12,13, les deux poulies étant mécaniquement couplées par une courroie sans fin, crantée, 14. La paire de poulies 12,13 est couplée à un axe d'entraínement du moteur 2, via une poulie 16 solidaire de cet axe, une courroie 17 et une poulie 15, ici supposée solidaire de l'ensemble formé par la poulie 13 et par l'organe 11. Les mouvements de rotation de chaque poulie crantée 12,13 sont donc transmis à l'arbre de commande principal 1 et à l'arbre secondaire 5 de la commande et inversement.
La mise en rotation manuelle d'un des organes 10, 11 au moyen de la manivelle emmanchée sur le carré solidaire de cet organe, entraíne donc une rotation de l'arbre du moteur 2 qui se traduit par des rotations correspondantes de l'arbre principal 1 et de l'arbre secondaire 5, lorsque les rotations de ces arbres ne sont pas électriquement obtenues par mise en marche du moteur 2.In the embodiment shown, each of the members 10,11 is integral with a pulley 12,13, the two pulleys being mechanically coupled by an endless belt, toothed, 14. The pair of pulleys 12,13 is coupled to an axis d drive of the motor 2, via a pulley 16 secured to this axis, a belt 17 and a pulley 15, here assumed to be integral with the assembly formed by the pulley 13 and by the member 11. The rotational movements of each toothed pulley 12,13 are therefore transmitted to the main control shaft 1 and to the secondary shaft 5 of the control and vice versa.
The manual rotation of one of the members 10, 11 by means of the crank fitted on the square integral with this member, therefore causes a rotation of the motor shaft 2 which results in corresponding rotations of the main shaft 1 and of the secondary shaft 5, when the rotations of these shafts are not electrically obtained by starting the motor 2.

Des volets mobiles 18,19 constituant des sélecteurs de mode de fonctionnement sont prévus au niveau de la commande.Movable flaps 18, 19 constituting mode selectors operation are provided at the command level.

Dans la réalisation présentée, chacun de ces volets 18,19 est fixé sur un arbre 30,31 dont seule une extrémité est représentée. Ces arbres ont des axes XX' et YY' parallèles et ils permettent aux volets de tourner en restant parallèles à la paroi 6 qu'ils traversent, les volets étant ici supposés de l'autre côté de cette paroi 6 par rapport aux arbres 1,5 et à la pièce 7. Chaque volet 18,19 a par exemple un fond circulaire qui présente localement une échancrure de passage de manivelle en périphérie. Cette échancrure est ici supposée réalisée en forme de demi-lune, son dimensionnement et son positionnement sont choisis, de manière connue en soi, en relation avec ceux prévus en paroi 6 pour l'entrée de manivelle, avec laquelle le volet portant cette échancrure doit coopérer. Chaque volet n'autorise l'insertion de la manivelle M, dans l'entrée de manivelle qui lui correspond, que quand la rotation du volet conduit son échancrure à se trouver en regard de l'entrée qu'elle découvre.In the embodiment presented, each of these components 18.19 is fixed on a shaft 30,31 of which only one end is shown. These trees have axes XX 'and YY' parallel and they allow the shutters to rotate while remaining parallel to wall 6 which they pass through, the flaps here being assumed to be on the other side of this wall 6 with respect to the trees 1.5 and to the part 7. Each flap 18,19 for example has a circular bottom which locally has a notch of passage of crank in periphery. This notch is here assumed to be in the shape of a half-moon, its design and positioning are chosen, in a manner known per se, in relation to those provided in wall 6 for the crank entry, with which the flap wearing this notch must cooperate. Each section only authorizes the insertion of the crank M, in the crank entry which corresponds to it, only when the rotation of the flap causes its notch to be located opposite the entrance that she discovers.

Dans l'exemple de réalisation présenté, chaque volet de sélection 18, 19 coopère avec un capot pivotant 27,28 qui est monté sur la paroi 6 à proximité de l'entrée de manivelle lui correspondant, ce volet permettant d'obturer ou de dégager cette entrée par basculement. Chaque capot est disposé par rapport au volet avec lequel il coopère de manière à ne pouvoir être relevé pour dégager une entrée de manivelle que lorsque l'échancrure du volet associé à cette entrée est située au niveau de cette dernière. Dans la réalisation présentée, ceci est obtenu en disposant l'axe de rotation du capot de l'autre côté de l'entrée de manivelle par rapport au volet qui vient surplomber le capot de manière à l'empêcher d'être soulevé, tant que l'échancrure ne se trouve pas au niveau de l'entrée.In the embodiment shown, each selection component 18, 19 cooperates with a pivoting cover 27, 28 which is mounted on the wall 6 to near the crank entry corresponding to it, this flap allowing to close or clear this entry by tilting. Each cover is arranged in relation to the shutter with which it cooperates so that it cannot be raised to clear a crank entry only when the notch of the pane associated with this entry is located at the latter. In the embodiment presented, this is obtained by arranging the axis of rotation of the cover on the other side of the crank inlet relative to the flap that comes overhang the hood so as to prevent it from being lifted, as long as the notch is not at the entrance.

Par ailleurs, l'axe de rotation 30,31, sur lequel est monté un volet 18,19, porte un bras de verrouillage 22,23, qui est logé de l'autre côté de la paroi 6 par rapport aux volets et qui tourne avec le volet monté sur le même axe que lui. Chaque bras de verrouillage a une extrémité libre munie d'un téton 24,25 qui est assujetti dans une des pistes P1, P2 de la pièce 7. Suivant la position atteinte en rotation par la pièce 7, chaque bras qui est lié en mouvement avec un volet, est contrôlé dans ses mouvements par la piste de cette pièce 7 où il est assujetti par son téton, cette piste étant prévue pour permettre une immobilisation du volet dans une certaine position. Les pistes P1, P2 sont constituées par des chemins de came ici ménagés au niveau de la surface supérieure du disque que forme la pièce 7.Furthermore, the axis of rotation 30.31, on which a flap 18.19 is mounted, carries a locking arm 22,23, which is housed on the other side of the wall 6 relative to the flaps and which rotates with the flap mounted on the same axis as him. Each locking arm has a free end provided with a pin 25.25 which is secured in one of tracks P1, P2 in room 7. Depending on the position reached in rotation by the part 7, each arm which is linked in movement with a flap, is controlled in its movements by the track of this piece 7 where it is secured by its nipple, this track being provided to allow a immobilization of the shutter in a certain position. Tracks P1, P2 are formed by cam tracks here formed at the surface of the disc formed by the part 7.

Comme la pièce 7 tourne en même temps que l'arbre de commande principal 1, auquel elle est liée à travers l'arbre secondaire 5, elle a une position angulaire qui est représentative de celle de l'arbre principal. Par conséquent, il est prévu de former des pistes sur la pièce 7 qui permettent un certain mouvement des volets 18,19 pour des positions angulaires particulières de l'arbre principal, par exemple pour les positions qu'il occupe quand le sectionneur est commuté dans une certaine position de commutation.As part 7 rotates at the same time as the drive shaft main 1, to which it is linked through the secondary shaft 5, it has a angular position which is representative of that of the main shaft. Through Therefore, it is planned to form tracks on the part 7 which allow some movement of the flaps 18,19 for angular positions particular of the main tree, for example for the positions it occupies when the switch is switched to a certain position switching.

Comme cela est connu en mode électriquement commandé, un sectionneur à trois positions, qui inclut une position de fermeture, une position d'ouverture et de sectionnement et une position de mise à la terre, est déplacé successivement de sa position de fermeture vers sa position d'ouverture par une première rotation de l'arbre principal 1 de la commande, puis de sa position d'ouverture vers sa position de mise à la terre par une rotation supplémentaire de ce même arbre principal 1.As is known in electrically controlled mode, a three position disconnector, which includes a closed position, a open and disconnected position and an earthing position, is successively moved from its closed position to its position opening by a first rotation of the main shaft 1 of the control, then from its open position to its earthed position by a additional rotation of the same main shaft 1.

Selon l'invention, la commande manuelle du sectionneur est dissociée en une première commande manuelle pour la commutation fermeture/ouverture et en une seconde commande manuelle pour la commutation ouverture/mise à la terre. Plus particulièrement, la commande manuelle du sectionneur qui permet de le commuter de sa position de fermeture vers sa position d'ouverture ou inversement se fait en manoeuvrant le carré 10 avec la manivelle M insérée dans l'entrée de manivelle 8 et la commande manuelle du sectionneur pour le commuter de sa position d'ouverture vers sa position de mise à la terre ou inversement se fait en manoeuvrant le carré 11 avec la manivelle M insérée dans l'entrée de manivelle 9. Par conséquent, par une disposition appropriée des pistes P1, P2 qui est choisie pour immobiliser les volets 18,19 dans des conditions déterminées, il est possible d'autoriser ou d'interdire certaines séquences de commutation manuelle du sectionneur en empêchant ou en autorisant un mouvement de rotation de l'un ou l'autre des deux volets et donc l'insertion de la manivelle dans l'une ou l'autre des deux entrées de manivelle.According to the invention, the manual control of the disconnector is dissociated in a first manual command for switching closing / opening and in a second manual command for the opening / ground switching. More specifically, the command manual disconnector which allows to switch it from its position closing to its open position or vice versa is done by operating the square 10 with the crank M inserted in the entry of crank 8 and manual disconnector control to switch it from its open position to its earth position or vice versa done by maneuvering the square 11 with the crank M inserted in the entry of crank 9. Consequently, by an appropriate arrangement of tracks P1, P2 which is chosen to immobilize the flaps 18.19 under conditions determined, it is possible to authorize or prohibit certain sequences of manual switching of the disconnector by preventing or authorizing a rotational movement of one or the other of the two components and therefore the insertion of the crank in either of the two crank entries.

Comme indiqué précédemment, la pièce 7 présente une ouverture 26 permettant un passage de la manivelle M afin que celle-ci puisse être accouplée à un carré d'organe 10,11 quand l'entrée de manivelle 8,9 correspondante à ce carré est libérée par le volet 18,19 associé.As indicated previously, the part 7 has an opening 26 allowing passage of the crank M so that it can be coupled to a body square 10.11 when the crank input 8.9 corresponding to this square is released by the associated flap 18.19.

Sur la figure 1, on a représenté le volet 18 dans une position où il libère l'entrée de manivelle 8 servant à commuter manuellement le sectionneur d'une position d'ouverture vers une position de fermeture ou inversement. Le volet 19 est représenté dans une position où il est immobilisé en mouvement par la piste P2 de la pièce 7 et où il obture l'entrée de manivelle 9. Quand l'organe 10 est actionné en rotation à l'aide de la manivelle M, la pièce 7 se déplace en rotation jusqu'à ce que la manivelle vienne en butée contre un bord intérieur de l'ouverture 26. A l'issue de cette manoeuvre, le sectionneur est commuté dans une certaine position. La manivelle M peut être dégagée de l'entrée de manivelle 8 et le volet 18 peut être déplacé dans une position où il obture l'entrée de manivelle 8. Selon la forme des pistes P1, P2 réalisées sur la pièce 7, le volet 19 peut être maintenu immobilisé ou au contraire libéré à l'issue de cette commutation manuelle du sectionneur. Dans le dernier cas, le déplacement du volet 19 est rendu possible pour libérer l'entrée de manivelle 9 afin d'y introduire la manivelle M pour continuer la séquence de commutation manuelle du sectionneur à l'aide de l'organe 11. La mise en mouvement de cet organe 11 à l'aide de la manivelle M provoque encore une rotation de la pièce 7 conduisant à une immobilisation du volet 18 par les pistes de cette pièce, par exemple tant que le sectionneur n'est pas commuté dans une position d'ouverture. On comprend donc que selon la forme des pistes de la pièce 7, il est possible d'interdire certaines séquences de commutation du sectionneur.In Figure 1, there is shown the flap 18 in a position where it releases the crank input 8 used to manually switch the disconnector from an open position to a closed position or vice versa. The flap 19 is shown in a position where it is immobilized in motion by track P2 in room 7 and where it closes the crank inlet 9. When the member 10 is actuated in rotation using the crank M, the part 7 is rotates until the crank abuts against a inner edge of opening 26. At the end of this operation, the disconnector is switched to a certain position. Crank M can be released of the crank inlet 8 and the flap 18 can be moved into a position where it closes the crank inlet 8. Depending on the shape of the tracks P1, P2 made on part 7, the flap 19 can be kept immobilized or at otherwise released after this manual switching of the disconnector. In the latter case, the movement of the flap 19 is made possible for release the crank entry 9 in order to introduce the crank M therein continue the manual switching sequence of the disconnector using the organ 11. The setting in motion of this organ 11 using the crank M again causes rotation of the part 7 leading to a immobilization of the flap 18 by the tracks of this part, for example while that the disconnector is not switched to an open position. We therefore understands that depending on the shape of the tracks in part 7, it is possible prohibit certain switching sequences of the disconnector.

Comme visible sur la figure 1, la pièce 7 est placée en bout d'arbre secondaire 5 de façon à être facilement accessible pour pouvoir être remplacée. Les pistes de la pièce 7 peuvent être formées par usinage ou par moulage.As visible in Figure 1, part 7 is placed at the end of the shaft secondary 5 so as to be easily accessible so that it can be replaced. The tracks of part 7 can be formed by machining or by molding.

Les sous-ensembles mobiles qui incluent chacun un volet 18,19 et un bras de verrouillage 22,23 porté par un même axe 30,31 et qui coopèrent avec la pièce 7 sont susceptibles d'être exploités pour agir directement ou indirectement sur des relais, non représentés, permettant de déterminer la position occupée par un sous-ensemble et donc par le sectionneur, à des fins de contrôle, en particulier lorsque ce sectionneur est électriquement actionné. Ces relais peuvent en particulier être exploités pour interdire une commutation électrique du sectionneur que ce soit pour une ouverture/fermeture ou pour une mise à la terre. Ainsi, une position particulière des volets conduisant à la mise hors service de la commutation électrique du sectionneur peut éventuellement être intégrée dans la logique d'interverrouillage implantée dans la pièce 7.The mobile sub-assemblies which each include a flap 18,19 and a locking arm 22,23 carried by the same axis 30,31 and which cooperate with Exhibit 7 are likely to be exploited to act directly or indirectly on relays, not shown, used to determine the position occupied by a sub-assembly and therefore by the disconnector, at control purposes, especially when this disconnector is electrically actuated. These relays can in particular be used to prohibit a electrical switching of the disconnector whether for a open / close or for earthing. So a position particular of the shutters leading to the switching off of the switching electric switch can optionally be integrated in the logic interlock installed in room 7.

Le positionnement et la commande de ces relais ne sont pas développés ici dans la mesure où ils sont susceptibles d'être obtenus par mise en oeuvre de techniques connues.The positioning and control of these relays are not developed here as far as they are likely to be obtained by implementation of known techniques.

La pièce 7 est également exploitée à des fins de blocage et plus particulièrement en tant que butée de fin de course pour la commutation manuelle du sectionneur, dans sa position intermédiaire d'ouverture, au moyen d'une manivelle M traversant l'ouverture 26 prévue dans par cette pièce. Dans la réalisation présentée sur la figure 1, l'ouverture 26 s'étend sur un secteur correspondant à une moitié du disque que forme la pièce 7, l'autre moitié de ce disque étant pleine et rainurée par les pistes P1 et P2.
L'arbre secondaire 5 et les carrés des organes 10,11 sont disposés respectivement aux sommets d'un triangle isocèle de telle sorte qu'en position d'ouverture du sectionneur, le bord du demi-disque plein délimitant l'ouverture 26 à l'intérieur de la pièce 7 s'étend perpendiculairement à une ligne passant par les axes de rotation des deux organes 10,11 et permet l'engagement de la manivelle sur l'un ou l'autre des carrés de ces organes 10,11. Sur la figure 1, l'arbre principal 1 de la commande occupe une position angulaire correspondant par exemple à la position de fermeture du sectionneur. Dans cette position, la pièce 7 permet l'engagement de la manivelle M sur le carré de l'organe 10 à travers l'entrée de manivelle 8 mais s'interpose entre l'entrée de manivelle 9 et le carré de l'organe 11 de sorte qu'elle est exploitée à des fins de blocage pour empêcher l'engagement de la manivelle M sur ce carré. Quand la manivelle M en prise sur le carré de l'organe 10 est manoeuvrée, le mouvement de rotation de la manivelle M est transmis à l'arbre principal 1 pour commuter le sectionneur de sa position de fermeture vers sa position d'ouverture. Le mouvement rotatif de l'arbre principal 1 est transmis à l'arbre secondaire 5 avec pour effet un mouvement rotatif de la pièce 7 comme illustré par une flèche sur cette pièce. Le disque que forme la pièce 7 balaye donc un plan que coupe la manivelle M contre laquelle il vient en butée. Il suffit donc de régler le rapport de démultiplication entre l'arbre secondaire 5 et l'arbre principal 1 pour obtenir un blocage du mouvement rotatif de la manivelle M par l'intermédiaire de la pièce 7 quand le sectionneur atteint sa position d'ouverture. En particulier, le disque effectue environ un quart de tour quand le sectionneur est commuté manuellement de sa position de fermeture à sa position d'ouverture. Quand le sectionneur occupe sa position d'ouverture, la manivelle M peut être engagée sur le carré de l'organe 11. Si maintenant la manivelle M en prise sur ce carré d'organe 11 est manoeuvrée, le mouvement de rotation de la manivelle M est transmis à l'arbre principal 1 pour commuter le sectionneur de sa position d'ouverture vers sa position de mise à la terre. Le mouvement rotatif de l'arbre principal 1 est transmis à l'arbre secondaire 5 avec pour effet un mouvement rotatif de la pièce 7 comme illustré par la flèche sur la figure 1. Le disque constituant la pièce 7 se déplace donc encore d'un quart de tour environ. Quand le sectionneur est dans sa position de mise à la terre, le disque occupe une position angulaire selon laquelle le bord du demi-disque plein délimitant l'ouverture 26 à l'intérieur de la pièce 7 est disposé sensiblement perpendiculairement à une ligne passant par les axes de rotation des deux organes 10,11. La pièce 7 s'interpose alors entre l'entrée de manivelle 8 et le carré de l'organe 10 de sorte qu'il empêche maintenant l'engagement de la manivelle M sur ce carré à travers cette entrée 8. Un mouvement rotatif en sens inverse de la manivelle M sur le carré 11 fait commuter le sectionneur de sa position de mise à la terre à sa position d'ouverture. La pièce 7 se déplace donc en rotation d'un quart de tour environ en sens inverse de la flèche portée par cette pièce et vient en butée contre la manivelle M quand le sectionneur atteint sa position d'ouverture ce qui bloque le mouvement rotatif de la manivelle.The part 7 is also used for blocking purposes and more particularly as a limit stop for manual switching of the disconnector, in its intermediate opening position, by means of a crank M passing through the opening 26 provided in by this room. In the embodiment shown in FIG. 1, the opening 26 extends over a sector corresponding to one half of the disc formed by the part 7, the other half of this disc being solid and grooved by tracks P1 and P2.
The secondary shaft 5 and the squares of the members 10, 11 are disposed respectively at the vertices of an isosceles triangle so that, in the disconnector opening position, the edge of the solid half-disc delimiting the opening 26 to 1 inside the part 7 extends perpendicularly to a line passing through the axes of rotation of the two members 10,11 and allows the engagement of the crank on one or the other of the squares of these members 10,11. In FIG. 1, the main shaft 1 of the control occupies an angular position corresponding for example to the closed position of the disconnector. In this position, the part 7 allows the engagement of the crank M on the square of the member 10 through the crank inlet 8 but is interposed between the crank inlet 9 and the square of the member 11 so that it is used for blocking purposes to prevent the engagement of the crank M on this square. When the crank M engaged on the square of the member 10 is operated, the rotational movement of the crank M is transmitted to the main shaft 1 to switch the disconnector from its closed position to its open position. The rotary movement of the main shaft 1 is transmitted to the secondary shaft 5 with the effect of a rotary movement of the part 7 as illustrated by an arrow on this part. The disc that forms the part 7 therefore sweeps a plane that cuts the crank M against which it abuts. It therefore suffices to adjust the reduction ratio between the secondary shaft 5 and the main shaft 1 in order to obtain a blocking of the rotary movement of the crank M by means of the part 7 when the disconnector reaches its open position. In particular, the disc makes about a quarter turn when the disconnector is manually switched from its closed position to its open position. When the disconnector occupies its open position, the crank M can be engaged on the square of the member 11. If now the crank M engaged on this square of the member 11 is operated, the rotational movement of the crank M is transmitted to the main shaft 1 to switch the disconnector from its open position to its earthing position. The rotary movement of the main shaft 1 is transmitted to the secondary shaft 5 with the effect of a rotary movement of the part 7 as illustrated by the arrow in FIG. 1. The disc constituting the part 7 therefore moves still one about a quarter turn. When the disconnector is in its earthing position, the disc occupies an angular position according to which the edge of the solid half-disc delimiting the opening 26 inside the part 7 is disposed substantially perpendicular to a line passing through the axes of rotation of the two members 10,11. The part 7 then comes between the crank inlet 8 and the square of the member 10 so that it now prevents the engagement of the crank M on this square through this inlet 8. A rotary movement in the direction reverse of the crank M on the square 11 switches the disconnector from its earthing position to its open position. The part 7 therefore moves in rotation about a quarter of a turn in the opposite direction to the arrow carried by this part and comes into abutment against the crank M when the disconnector reaches its open position which blocks the rotary movement of the crank.

La figure 2 montre la position de la pièce 7 en butée contre la manivelle M quand le sectionneur est dans une position d'ouverture suite à sa commutation manuelle de sa position de mise à la terre vers sa position d'ouverture. La figure 3 montre la position de la pièce 7 en butée contre la manivelle M quand le sectionneur est dans sa position d'ouverture suite à sa commutation manuelle de sa position de fermeture vers sa position d'ouverture.Figure 2 shows the position of the part 7 in abutment against the crank M when the disconnector is in an open position following its manual switching from its earthing position to its position opening. Figure 3 shows the position of the part 7 in abutment against the crank M when the disconnector is in its open position following its manual switching from its closed position to its position opening.

Comme montré sur les figures 1 à 3, la manivelle comporte une languette ou clavette 34 qui s'étend selon une direction radiale pour venir en butée contre un premier épaulement 20 de la pièce 7, à la fin de la commutation manuelle du sectionneur de sa position de mise à la terre vers sa position d'ouverture, lorsque la manivelle M est en prise sur un carré d'organe. L'épaulement 20 est situé à la limite entre le bord intérieur de l'ouverture 26 et la moitié pleine du disque formant la pièce 7, à proximité de l'axe de rotation de cette pièce La languette 34 traverse le plan balayé par le disque 7, quand la manivelle est en prise sur l'un ou l'autre des deux carrés d'organes 10,11. La pièce 7 comporte un second épaulement 21 sur lequel vient en butée la languette 34 à la fin de la commutation manuelle du sectionneur de sa position de fermeture vers sa position d'ouverture. Les deux épaulements 20 et 21 sont similairement disposés sur un diamètre de la pièce 7 de part et d'autre de l'axe de rotation de la pièce 7 qui se confond avec celui de l'arbre secondaire 5, ils sont de préférence le plus près possible de cet axe pour réduire au maximum le couple de torsion exercée par la manivelle M sur la pièce 7, lorsqu'elle vient en butée. La languette 34 et les deux épaulements 20,21 sont ajustés de telle manière que pour un tour de manivelle, la languette 34 passe devant un des épaulements et qu'au tour suivant de la manivelle, elle vienne en butée contre l'autre.As shown in Figures 1 to 3, the crank has a tongue or key 34 which extends in a radial direction to come into abutment against a first shoulder 20 of the part 7, at the end of the manual switching of the disconnector from its earthing position to its open position, when the crank M is engaged on a square member. The shoulder 20 is located at the limit between the inner edge of the opening 26 and the full half of the disc forming the part 7, near the axis of rotation of this part The tongue 34 crosses the plane swept by the disc 7, when the crank is engaged on one or the other of the two squares of organs 10.11. The part 7 has a second shoulder 21 on which the tongue 34 abuts at the end of the manual switching of the disconnector from its closed position to its open position. The two shoulders 20 and 21 are similarly arranged over a diameter of the part 7 on either side of the axis of rotation of the part 7 which merges with that of the secondary shaft 5, they are preferably the closest possible from this axis to minimize the torque exerted by the crank M on the part 7, when it comes into abutment. Tongue 34 and the two shoulders 20,21 are adjusted so that for a turn of the crank, the tongue 34 passes in front of one of the shoulders and next turn of the crank, it comes into abutment against the other.

En dernier lieu, dans la réalisation présentée et de manière connue, chaque volet 17,18 est destiné à coopérer avec une serrure S1, S2. A cet effet, il comporte un fond qui est localement muni d'un rebord périphérique doté d'une ou de plusieurs ouvertures, telles 32 et 33, dans lesquelles peuvent s'engager un pêne, tel 35, d'une serrure ou d'immobilisation de volet, manoeuvrables à l'aide de clés. Comme connu, ces ouvertures sont ménagées de manière à permettre d'interdire par clé certaines séquences de commutation manuelle ou électrique du sectionneur avec la commande.Finally, in the realization presented and in a known manner, each flap 17,18 is intended to cooperate with a lock S1, S2. In this indeed, it has a bottom which is locally provided with a peripheral rim with one or more openings, such as 32 and 33, in which can engage a bolt, such as 35, of a lock or immobilization of flap, maneuverable using keys. As is known, these openings are arranged in such a way as to allow certain sequences to be prohibited by key manual or electrical switching of the disconnector with the control.
