Description

DOMAINE TECHNIQUE ET ART ANTÉRIEURTECHNICAL FIELD AND PRIOR ART

La présente invention se rapporte à un dispositif de commande d'un appareillage électrique moyenne ou haute tension et à un appareillage électrique moyenne ou haute tension comportant un tel dispositif de commande et à un procédé de commande d'un appareillage électrique moyenne ou haute tension.The present invention relates to a control device of a medium or high voltage electrical equipment and a medium or high voltage electrical equipment comprising such a control device and a control method of medium or high voltage electrical equipment.

Les postes de distribution de courant, par exemple les postes à moyenne tension, comprennent deux organes : un premier interrupteur qui établit ou coupe le passage du courant dans le poste et un second interrupteur qui permet de relier au potentiel 0V les câbles du poste de distribution. Le second interrupteur est une protection de l'opérateur, par exemple pour effectuer une maintenance.The current distribution stations, for example the medium voltage substations, comprise two components: a first switch that establishes or cuts the passage of the current in the substation and a second switch that makes it possible to connect the cables of the distribution station to the potential 0V. . The second switch is a protection of the operator, for example to perform maintenance.

Les organes sont commandés par un mécanisme de commande à ressort, à tumbler ou à cames, avec un passage par un point mort. Ce type de mécanisme est principalement utilisé pour des appareillages à moyenne tension. Cependant il s'applique également à des activités de transport et de distribution à haute tension.The members are controlled by a spring, tumbler or cam mechanism with a neutral passage. This type of mechanism is mainly used for medium voltage switchgear. However, it also applies to high voltage transmission and distribution activities.

L'interrupteur est manoeuvré soit manuellement à l'aide d'un levier amovible, soit de manière motorisée à l'aide d'un moteur électrique.The switch is operated either manually using a removable lever, or motorized using an electric motor.

Quant au sectionneur de terre, celui-ci est manoeuvré manuellement à l'aide du même levier ou d'un levier dédié.As for the earthing switch, it is operated manually using the same lever or a dedicated lever.

De manière connue, un appareillage électrique comportant un interrupteur et un sectionneur de terre comporte une platine avant et une platine arrière entre lesquelles est placé le mécanisme de commande de l'interrupteur et du sectionneur de terre.In known manner, an electrical apparatus comprising a switch and an earthing switch comprises a front plate and a rear plate between which is placed the control mechanism of the switch and the earthing switch.

Lorsque la commande de l'interrupteur est motorisée, le système de motorisation se situe généralement entre deux platines.When the control of the switch is motorized, the motorization system is generally between two plates.

Le système de motorisation comporte un moteur électrique et un réducteur interposé entre le moteur électrique et un axe du mécanisme de commande de l'interrupteur.The motorization system comprises an electric motor and a reducer interposed between the electric motor and an axis of the control mechanism of the switch.

Le moteur est un moteur universel à un sens de rotation, l'arbre de sortie du moteur attaquant le réducteur. Un système de bielle-manivelle, actionné en traction-compression placé à la sortie du réducteur, permet la rotation du mécanisme à ressort dans les deux sens de rotation.The motor is a universal motor with a direction of rotation, the output shaft of the motor attacking the gearbox. A crank-rod system, actuated in tension-compression placed at the outlet of the reducer, allows the rotation of the spring mechanism in both directions of rotation.

Dans le cas d'une manoeuvre électrique interrompue, i.e. n'ayant pu conduire à une ouverture ou fermeture de l'interrupteur, il est requis de pouvoir terminer la commutation de manière manuelle.In the case of an interrupted electric operation, i.e. not being able to lead to an opening or closing of the switch, it is required to be able to terminate the switch manually.

Dans certains systèmes, il est prévu d'agir avec une manivelle en face avant du système électrique ; dans d'autres systèmes, par contre il est prévu d'agir directement sur un étage du réducteur à l'aide d'un outil spécifique.In some systems, it is intended to operate with a crank on the front of the electrical system; in other systems, however, it is planned to act directly on a stage of the gearbox using a specific tool.

Lorsque le sectionneur de terre est fermé, un inter-verrouillage empêche la manoeuvre manuelle de l'interrupteur en interdisant la mise en place du levier de commande et un ou plusieurs micro-contacts interdisent l'alimentation du moteur, et par conséquent la fermeture de l'interrupteur.When the earthing switch is closed, an interlock prevents the manual operation of the switch by prohibiting the installation of the control lever and one or more micro-contacts prohibit the power supply of the motor, and therefore the closure of the switch.

En outre, certaines normes prévoient un verrouillage mécanique empêchant une fermeture électrique de l'interrupteur en cas de défaillance des micro-contacts, ainsi que la fusion d'un fusible protégeant le moteur en moins d'une seconde. Ce verrouillage mécanique est généralement assuré par un système de pignons et de bielles.In addition, some standards provide for a mechanical interlock that prevents electrical shutdown of the switch in the event of microswitch failure, as well as fusing of a fuse protecting the motor in less than one second. This mechanical locking is usually provided by a system of pinions and connecting rods.

La conception et la mise au point de ce mécanisme de verrouillage mécanique sont difficiles.The design and development of this mechanical locking mechanism is difficult.

Les systèmes de sécurité et de commande manuelle ont un prix de revient élevé, en outre ils peuvent être difficiles à mettre en oeuvre sur site.Security and manual control systems have a high cost, and they can be difficult to implement on site.

C'est par conséquent un but de la présente invention d'offrir un système électrique à actionnement motorisé simple et de prix de revient réduit, empêchant toute commutation intempestive de l'interrupteur alors que le sectionneur de terre est fermé.It is therefore an object of the present invention to provide a power system with simple motorized operation and low cost, preventing any inadvertent switching of the switch while the earthing switch is closed.

Le but précédemment énoncé est atteint par un système de motorisation, dans lequel au moins un élément de transmission de puissance du moteur au mécanisme de commande de l'interrupteur est amovible, afin d'interrompre la chaîne cinématique de puissance.The previously stated goal is achieved by a motorization system, in which at least one power transmission element of the motor at the Switch control mechanism is removable, in order to interrupt the power kinematic chain.

En d'autres termes, il est prévu de rompre la liaison mécanique entre le moteur électrique et la commande de l'interrupteur pour pouvoir fermer le sectionneur de terre. Ainsi, il n'existe aucun risque de commutation intempestive de l'interrupteur par remise en route du moteur, alors que le sectionneur de terre est fermé.In other words, it is planned to break the mechanical connection between the electric motor and the control of the switch to be able to close the earthing switch. Thus, there is no risk of inadvertent switching of the switch by restarting the engine, while the earthing switch is closed.

Dans un mode préféré de réalisation, l'élément amovible est un pignon manivelle directement en prise avec le mécanisme de commande de l'interrupteur.In a preferred embodiment, the removable element is a crank pinion directly engaged with the control mechanism of the switch.

Cette unique pièce permet d'assurer les foncions suivantes :

  • Lorsqu'il est en place :
    1. a) il permet de transmettre l'énergie pour commander électriquement le mécanisme de commande de l'interrupteur,
    2. b) il permet d'obturer, les orifices de commande manuelle du mécanisme, et donc d'interdire une manoeuvre manuelle du mécanisme de commande,
    3. c) il interdit les manoeuvres du sectionneur de terre par l'intermédiaire d'un système d'inter-verrouillage.
  • Lorsqu'il est retiré :
    1. a) il permet de désaccoupler cinématiquement la motorisation, et donc d'interdire toute manoeuvre électrique,
    2. b) de désobturer les orifices de commande manuelle,
    3. c) de libérer (si l'interrupteur est ouvert) l'obturateur du sectionneur de terre, et donc de permettre sa commande.
This single piece ensures the following functions:
  • When in place:
    1. a) it transmits the energy to electrically control the control mechanism of the switch,
    2. b) it allows to close the manual control ports of the mechanism, and thus to prohibit a manual operation of the control mechanism,
    3. c) it prohibits the operation of the earthing switch via an interlocking system.
  • When removed:
    1. a) it makes it possible to uncouple the motorization kinematically, and thus to prohibit any electric maneuver,
    2. (b) unclog the manual control orifices,
    3. c) to release (if the switch is open) the shutter of the earthing switch, and thus to allow its control.

La présente invention a alors pour objet un dispositif de commande d'un interrupteur associé à un sectionneur de terre, ledit dispositif comportant des moyens motorisés pour commander un mécanisme de commande de l'interrupteur et/ou un mécanisme de commande du sectionneur de terre, lesdits moyens motorisés comportant au moins un moto-réducteur, au moins un moteur électrique et au moins un réducteur, ledit réducteur comportant au moins un premier pignon en prise avec un arbre du moteur et au moins un deuxième pignon en prise avec le mécanisme de commande de l'interrupteur et/ou du sectionneur de terre, et des moyens pour transmettre la rotation du premier pignon au deuxième pignon, au moins l'un des éléments du réducteur parmi le premier pignon, le deuxième pignon et les moyens de transmission de la rotation entre le premier et le deuxième pignon étant retirable et replaçable pour interrompre, respectivement rétablir une chaîne cinématique de transmission de puissance entre le moteur électrique et le mécanisme de commande de l'interrupteur et/ou du sectionneur de terre , dans lequel ledit élément est le deuxième pignon, celui-ci obturant un accès au mécanisme de commande manuelle de l'interrupteur et/ou du sectionneur de terre lorsqu'il établit la chaîne cinématique de transmission de puissance entre le moteur électrique et le mécanisme de commande de l'interrupteur et/ou du sectionneur de terre, et libérant cet accès lorsqu'il est retiré, interrompant ainsi une chaîne cinématique de transmission de puissance entre le moteur électrique et le mécanisme de commande de l'interrupteur et/ou du sectionneur de terre.The subject of the present invention is therefore a device for controlling a switch associated with an earthing switch, said device comprising motorized means for controlling a mechanism for controlling the switch and / or a control mechanism for the earthing switch. said motorized means comprising at least one geared motor, at least one electric motor and at least one gearbox, said gearbox comprising at least one first gear engaged with a motor shaft and at least one second gear engaged with the control mechanism of the switch and / or the earthing switch, and means for transmitting the rotation of the first gear to the second gear, at least one of the elements of the gear among the first gear, the second gear and the transmission means of the rotation between the first and the second gear being removable and replaceable to interrupt, respectively restore a transmission kinematic chain of then between the electric motor and the control mechanism of the switch and / or the earthing switch, wherein said element is the second pinion, which closes an access to the manual control mechanism of the switch and / or the earthing switch when it establishes the power transmission kinematic chain between the electric motor and the control mechanism of the switch and / or the earthing switch, and releasing this access when it is removed, thus interrupting a power transmission kinematic chain between the electric motor and the control mechanism of the switch and / or the earthing switch.

Le deuxième pignon est par exemple déplaçable selon un mouvement de translation le long de son axe de rotation.The second pinion is for example movable in a translational movement along its axis of rotation.

De manière avantageuse, le deuxième pignon est disposé en face avant dudit dispositif, et le moto-réducteur est disposé en face avant dudit dispositif de commande. Ce qui facilite l'accessibilité au dispositif de commande et facilite la réalisation dudit dispositifAdvantageously, the second gear is disposed on the front face of said device, and the geared motor is disposed on the front face of said control device. This facilitates the accessibility of the control device and facilitates the realization of said device

Le deuxième pignon est par exemple un pignon manivelle engrenant le premier pignon, ledit pignon manivelle comportant un axe en saillie et un ergot excentré entraînant un élément du mécanisme de commande.The second pinion is for example a crank pinion meshing with the first pinion, said crank pinion having a projecting pin and an eccentric pin driving an element of the control mechanism.

De manière particulièrement avantageuse, le dispositif selon la présente invention comporte des obturateurs pour empêcher l'accès aux mécanismes de commande de l'interrupteur et du sectionneur de terre, et des moyens d'inter-verrouillage pour éviter le retrait simultané des deux obturateurs interdisant donc la fermeture simultanée de l'interrupteur et du sectionneur de terre.Particularly advantageously, the device according to the present invention comprises shutters to prevent access to the control mechanisms of the switch and the earthing switch, and interlocking means to prevent the simultaneous removal of the two shutters prohibiting therefore the simultaneous closing of the switch and the earthing switch.

Les obturateurs sont par exemple des palettes mobiles en rotation autour d'un axe et les moyens d'inter-verrouillage comportent une tige d'interconnexion reliant les deux palettesThe shutters are for example pallets movable in rotation about an axis and the interlocking means comprise an interconnect rod connecting the two pallets

Le dispositif peut également comporter des moyens d'immobilisation en translation du deuxième pignon, lesdits moyens étant formés par un capot mobile en rotation par rapport au deuxième pignon et apte à venir s'immobiliser en translation et en rotation par rapport au dispositif de commande. Ainsi le pignon manivelle ne peut s'échapper de manière involontaire et le capot sert également de moyen de préhension.The device may also comprise immobilization means in translation of the second pinion, said means being formed by a cover movable in rotation relative to the second pinion and adapted to come to rest in translation and in rotation with respect to the control device. Thus the crank pinion can not escape unintentionally and the hood also serves as a gripping means.

Ces moyens d'immobilisation peuvent comporter deux pattes diamétralement opposées en saillie radialement et destinées à venir s'engager par rotation autour de l'axe du deuxième pignon avec des butées axiales portées par un appareillage comportant ledit interrupteur et ledit sectionneur de terre associéThese immobilizing means may comprise two diametrically opposed lugs projecting radially and intended to come to engage by rotation about the axis of the second gear with axial stops carried by an apparatus comprising said switch and said associated earthing switch

Le dispositif selon la présente invention comporte, de manière avantageuse des capteurs, par exemple des micro-contacts de position de l'interrupteur et du sectionneur et des éléments du moto-réducteur, permettant la détection des positions de l'interrupteur et du sectionneur de terre et la commande de l'alimentation du moteur électrique et la présence du capot amovible.The device according to the present invention advantageously comprises sensors, for example microswitches of the position of the switch and the disconnector and elements of the geared motor, enabling the positions of the switch and the disconnector to be detected. earth and the control of the power supply of the electric motor and the presence of the removable hood.

La fermeture du sectionneur de terre détectée par les micro-contacts peut provoquer la mise en court-circuit du moto-réducteur.Closing the earthing switch detected by the microswitches may cause the geared motor to short-circuit.

Afin de répondre à une norme de sécurité, le dispositif peut comporter un fusible apte à fondre lorsque le moteur est mis en court-circuit.In order to meet a safety standard, the device may include a fuse capable of melting when the motor is short-circuited.

EXPOSÉ DÉTAILLÉ DE MODES DE RÉALISATION PARTICULIERSDETAILED PRESENTATION OF PARTICULAR EMBODIMENTS

Sur la figure 1, on peut voir un exemple de mécanisme de commande à ressort, type tumbler, pour un poste de distribution à moyenne tension auquel peut être appliqué la présente invention.On the figure 1 an example of a tumbler spring type control mechanism for a medium voltage distribution station to which the present invention can be applied.

Sur la figure 1, la référence 2 désigne un tumbler de sectionneur de terre et la référence 4 un tumbler d'interrupteur. Le tumbler 2 est monté tournant sur un arbre 6 de sectionneur de terre et le tumbler 4 est monté tournant sur un arbre 8 d'interrupteur. Les arbres 6 et 8 sont métalliques. Ils sont montés entre une platine avant 44 (figure 7A) montée parallèlement à une platine arrière 43. Des colonnettes 12 sont montées entre la platine avant et la platine arrière. Ces colonnettes ont pour fonction de limiter le mouvement de rotation des tumblers 2 et 4. Un ressort 14 est monté entre le tumbler 2 et le tumbler 4. Le ressort 14 est monté pivotant à une extrémité sur le tumbler 2 autour d'un axe de ressort de sectionneur de terre 16 et il est monté pivotant, à son autre extrémité, sur le tumbler d'interrupteur 4 autour d'un axe 18 de ressort d'interrupteur. Un disque 20 est monté tournant sur le même arbre 8 que le tumbler d'interrupteur 4. Une bielle 22 est montée pivotante à l'une de ses extrémités sur le disque 20. A son autre extrémité, la bielle 22 est montée pivotante sur un entraîneur 24 qui entraîne l'interrupteur grâce à son axe.On the figure 1 , 2 denotes a disconnector tumbler and reference 4 a switch tumbler. The tumbler 2 is rotatably mounted on a disconnector shaft 6 and the tumbler 4 is rotatably mounted on a switch shaft 8. The shafts 6 and 8 are metallic. They are mounted between a front plate 44 ( Figure 7A ) mounted parallel to a rear plate 43. Columns 12 are mounted between the front plate and the rear plate. These columns serve to limit the rotational movement of the tumblers 2 and 4. A spring 14 is mounted between the tumbler 2 and the tumbler 4. The spring 14 is pivotally mounted at one end on the tumbler 2 about an axis of Earthing spring 16 and is pivotally mounted at its other end on the switch tumbler 4 about a switch spring axis 18. A disk 20 is rotatably mounted on the same shaft 8 as the switch tumbler 4. A connecting rod 22 is pivotally mounted at one of its ends on the disk 20. At its other end, the connecting rod 22 is pivotally mounted on a driver 24 which drives the switch through its axis.

On a représenté sur la figure 2 un tumbler faisant partie du mécanisme de la figure 1. Il comprend une partie centrale ou moyeu 30 et deux flasques parallèles 32. Chacun des flasques 32 comporte des zones de réception 34 en forme d'arc de cercle. Comme on peut le voir sur la figure 1, les zones de réception 34 sont destinées à recevoir la colonnette 12 lorsque l'interrupteur passe de la position ouverte à la position fermée et inversement.We have shown on the figure 2 a tumbler part of the mechanism of the figure 1 . It comprises a central portion or hub 30 and two parallel flanges 32. Each of the flanges 32 has reception zones 34 in the shape of a circular arc. As can be seen on the figure 1 the receiving zones 34 are intended to receive the column 12 when the switch passes from the open position to the closed position and vice versa.

On a représenté sur la figure 3 une vue en perspective d'un tumbler de sectionneur de terre. De la même manière, il comprend une partie centrale ou moyeu 36 et deux flasques parallèles 38 sur lesquels sont ménagées des zones de réception 40 en forme d'arc de cercle destinées à recevoir la colonnette 12 correspondante lorsque le tumbler passe de sa position ouverte à sa position fermée et inversement. Sur la figure 1, le mécanisme a été représenté sectionneur de terre en position ouverte et interrupteur en position ouverte également. On manoeuvre ce mécanisme à l'aide d'un levier de commande que l'on place sur le devant du mécanisme. Sur la figure 4, le tumbler 4 a pivoté de quelque dizaines de degrés de telle sorte que l'axe 18 du ressort s'est déplacé ce qui conduit à la position de point mort représentée sur la figure 4 dans laquelle le ressort est aligné avec l'axe de pivotement 8 du tumbler. A ce stade, seul le tumbler 4 et le ressort 14 sont en mouvement.We have shown on the figure 3 a perspective view of a disconnector tumbler. In the same way, it comprises a central portion or hub 36 and two parallel flanges 38 on which are formed reception zones 40 in the shape of a circular arc intended to receive the corresponding column 12 when the tumbler moves from its open position to its closed position and vice versa. On the figure 1 , the mechanism has been shown earthing switch in open position and switch in open position also. This mechanism is operated by means of a control lever which is placed on the front of the mechanism. On the figure 4 , the tumbler 4 has rotated a few tens of degrees so that the axis 18 of the spring has moved which leads to the neutral position shown on the figure 4 wherein the spring is aligned with the pivot axis 8 of the tumbler. At this stage, only the tumbler 4 and the spring 14 are moving.

Une fois passé le point mort, le ressort 14 se détend et prend le relais de l'opérateur : il entraîne le tumbler 4 d'interrupteur en rotation. Le levier de commande est débrayé et n'intervient plus dans la manoeuvre. Peu après le passage du point mort, le tumbler d'interrupteur entraîné en rotation vient taper sur le disque d'entraînement qui est lui-même entraîné en rotation. Le disque d'entraînement fait alors tourner l'entraîneur par l'intermédiaire de la bielle 22. La fonction de l'ensemble disque 20, bielle 22, entraîneur 24 est donc de délocaliser la manoeuvre. L'opérateur fait tourner le tumbler à un certain niveau, mais la manoeuvre effective de l'interrupteur se fait plus haut avec l'entraîneur 24.Once past the dead point, the spring 14 relaxes and takes over from the operator: it drives the rotary switch tumbler 4. The control lever is disengaged and no longer intervenes in the maneuver. Shortly after the passage of the neutral point, the switch tumbler rotated comes to hit the drive disk which is itself rotated. The drive disk then rotates the driver via the connecting rod 22. The function of the disk assembly 20, connecting rod 22, driver 24 is therefore to relocate the maneuver. The operator turns the tumbler to a certain level, but the effective operation of the switch is higher with the coach 24.

Du côté du sectionneur de terre 2, le fonctionnement est le même, mais sans déport de l'information. Le tumbler 2 actionne directement le sectionneur de terre sur l'appareillage électrique. Il existe donc aussi une phase d'accumulation d'énergie (compression du ressort par l'opérateur au moyen du levier de commande) et une phase de libération de cette énergie par la détente du ressort. Toutefois, la puissance dégagée est moins importante parce que la course de compression est plus faible. Le tumbler du sectionneur de terre passe ainsi de sa position ouverte représentée sur les figures 1, 4 et 5 à sa position fermée représentée sur la figure 6.On the side of the earthing switch 2, the operation is the same, but without deporting the information. The tumbler 2 directly actuates the earthing switch on the electrical equipment. There is therefore also a phase of energy accumulation (compression of the spring by the operator by means of the control lever) and a phase of release of this energy by the relaxation of the spring. However, the power released is less important because the compression stroke is lower. The earthing switch tumbler thus moves from its open position represented on the figures 1 , 4 and 5 to its closed position represented on the figure 6 .

Sur les figures 7A à 8C, on peut voir le dispositif de commande de l'interrupteur et du sectionneur de terre selon la présente invention de l'extérieur, du côté de la face avant du système, comportant une platine avant 44 et une platine arrière 43. La platine avant comporte des ouvertures 6.1, 8.1 d'accès aux tumbler respectivement du sectionneur de terre et de l'interrupteur. Les tumbler d'interrupteur et de sectionneur de terre se trouvent entre les platines arrière 43 et avant 44. L'ouverture 6.1 est cachée par un obturateur 6.2.On the Figures 7A to 8C , the control device of the switch and the earthing switch according to the present invention can be seen from the outside, on the side of the front face of the system, comprising a front plate 44 and a rear plate 43. The front plate has openings 6.1, 8.1 tumbler access respectively of the earthing switch and the switch. The tumble switch and earthing switch are located between the rear plates 43 and before 44. The opening 6.1 is hidden by a shutter 6.2.

Le mécanisme de commande de l'interrupteur est motorisé, et comporte un moto-réducteur 49 formé par un moteur électrique 46, type à courant continu ou universel piloté par des relais, et un réducteur 48 entre le moteur électrique et l'axe 8 du mécanisme de commande de l'interrupteur, afin d'appliquer une vitesse de rotation réduite à l'arbre d'entrée d'effort 8 de la commande d'interrupteur.The control mechanism of the switch is motorized, and comprises a gear motor 49 formed by an electric motor 46, DC or universal type driven by relays, and a gearbox 48 between the electric motor and the axis 8 of the control mechanism of the switch, in order to apply a reduced rotational speed to the force input shaft 8 of the switch control.

Le réducteur 48 comporte notamment un pignon, dit pignon manivelle 50, dont le détail est particulièrement visible sur la figure 9, en prise avec le tumbler d'interrupteur, et engrenant une roue dentée (non visible) du moto-réducteur qui peut être directement en prise avec l'arbre du moteur. En fait sur les figures, on peut voir un capot 62 recouvrant le pignon manivelle 50, mais pour la suite de la description pour des raisons de simplification, nous utiliserons le terme pignon manivelle pour désigner cette pièce.The gearbox 48 comprises in particular a pinion, said crank pinion 50, whose detail is particularly visible on the figure 9 , engaged with the switch tumbler, and meshing with a toothed gear (not visible) of the geared motor which can be directly engaged with the motor shaft. In fact in the figures, we can see a cover 62 covering the crank pinion 50, but for the following description for reasons of simplification, we will use the term crank pinion to designate this part.

Dans une variante de réalisation, le pignon manivelle 50 peut être entraîné par une chaîne ou une courroie facilement amovible.In an alternative embodiment, the crank pinion 50 can be driven by an easily removable chain or belt.

Dans un mode de réalisation particulier, le pignon 50 est dit pignon manivelle puisqu'il comporte un axe central 66, en saillie d'une face 50.2 du pignon 50, destiné à pénétrer dans l'ouverture 8.1 de la platine avant 44 autour duquel le pignon manivelle 50 tourne, et un ergot 54 excentré en saillie de la face 50.2 pénétrant dans une lumière 53 en forme d'arc de cercle centré sur l'orifice 8.1. L'ergot coopère avec une pièce d'entraînement du tumbler, permettant son entraînement et l'actionnement du tumbler. Le pignon 50 forme alors une manivelle.In a particular embodiment, the pinion 50 is said crank pinion since it comprises a central axis 66, projecting from a face 50.2 of the pinion 50, intended to penetrate into the opening 8.1 of the front plate 44 around which the crank pinion 50 rotates, and a lug 54 eccentric projecting from the face 50.2 penetrating into a light 53 in the shape of a circular arc centered on the orifice 8.1. The lug cooperates with a drive part of the tumbler, allowing its driving and the actuation of the tumbler. The pinion 50 then forms a crank.

Selon la présente invention, le pignon manivelle 50 est amovible, comme on peut le voir sur les figures 8A à 8C.According to the present invention, the crank pinion 50 is removable, as can be seen on the Figures 8A to 8C .

Il est disposé de manière décalée par rapport au moteur électrique 46 et à la roue dentée, afin de pouvoir être retiré selon une direction coaxiale à son axe de rotation par une simple translation. Ainsi aucun obstacle ne gêne le retrait du pignon manivelle 50.It is disposed offset from the electric motor 46 and the toothed wheel, so that it can be removed in a direction coaxial with its axis of rotation by a simple translation. Thus no obstacle hinders the withdrawal of the crank pinion 50.

Le pignon manivelle 50 permet donc, quand il est en place, de transmettre l'énergie pour commander électriquement le mécanisme de commande.The crank pinion 50 therefore allows, when it is in place, to transmit the energy to electrically control the control mechanism.

Lorsque le pignon-manivelle 50 est retiré, il permet un actionnement manuel au moyen d'un levier comme cela est représenté sur la figure 8C.When the crank pinion 50 is removed, it allows manual operation by means of a lever as shown in FIG. Figure 8C .

La manoeuvre manuelle du tumbler d'interrupteur s'effectue de la même manière que sur les mécanismes non motorisés. Un levier 72 à deux axes est introduit dans l'orifice 8.1 et la lumière 53, celui est tourné autour de l'axe de l'orifice 8.1 pour entraîner le tumbler à travers la lumière 53.The manual operation of the switch tumbler is carried out in the same way as on non-motorized mechanisms. A lever 72 with two axes is introduced into the orifice 8.1 and the light 53, that is turned around the axis of the orifice 8.1 to drive the tumbler through the light 53.

Le tumbler est placé en vis-à-vis des orifices 8.1 et de la lumière 53, ce qui permet autant au pignon manivelle 50 qu'au levier 72 de commande manuelle d'effectuer des manoeuvres sur le tumbler à travers la platine avant 44.The tumbler is placed opposite the orifices 8.1 and the light 53, which allows both the crank pinion 50 and the lever 72 for manual control to perform maneuvers on the tumbler through the front plate 44.

La platine avant 44 comporte également une lumière 55 en arc de cercle centrée sur l'ouverture 6.1 (figure 8C) pour permettre l'actionnement du mécanisme de commande du sectionneur de terre de manière similaire au mécanisme de commande de l'interrupteur.The front plate 44 also has an arcuate light 55 centered on the opening 6.1 ( Figure 8C ) to enable the operation of the control mechanism of the earthing switch in a manner similar to the control mechanism of the switch.

On pourrait prévoir, en variante, un pignon ne comportant qu'un axe central en prise directe avec le tumbler.One could provide, alternatively, a pinion having only a central axis in direct contact with the tumbler.

Le pignon manivelle 50 obture, lorsqu'il est en place l'orifice 8.1 et la lumière 53, il interdit alors une mise en place d'un levier et donc un actionnement manuel du mécanisme de commande.The crank pinion 50 closes, when it is in place the orifice 8.1 and the light 53, it then prohibits a setting up of a lever and thus a manual actuation of the control mechanism.

En outre, des obturateurs 6.2, 8.2 sont prévus pour obturer les orifices 6.1, 8.1 et les lumières 53, 55 respectivement.In addition, shutters 6.2, 8.2 are provided to close the openings 6.1, 8.1 and the lights 53, 55 respectively.

Ces obturateurs 6.2, 8.2 sont, dans l'exemple représenté, formés par des plaques mobiles en rotation autour d'un axe 6.3, 8.3 orthogonal à une plus grande surface de la platine avant 44.These shutters 6.2, 8.2 are, in the example shown, formed by plates movable in rotation about an axis 6.3, 8.3 orthogonal to a larger surface of the front plate 44.

Ainsi, pour accéder aux orifices 6.1, 8.1 et à la lumière 53, il suffit de faire pivoter manuellement l'obturateur correspondant 6.2, 8.2 autour de son axe 6.3, 8.3.Thus, to access the orifices 6.1, 8.1 and 53, it is sufficient to manually rotate the corresponding shutter 6.2, 8.2 about its axis 6.3, 8.3.

Des moyens de rappel (non représentés) sont prévus pour chacun des obturateurs pour les rappeler en position d'obturation des ouvertures 6.1, 8.1.Returning means (not shown) are provided for each shutter to return them to the closed position of the openings 6.1, 8.1.

Des moyens d'inter-verrouillage sont prévus entre les deux obturateurs 6.2, 8.2, disposés entres les deux platines pour empêcher le retrait simultané des deux obturateurs 6.2, 8.2.Interlocking means are provided between the two shutters 6.2, 8.2, arranged between the two plates to prevent the simultaneous removal of the two shutters 6.2, 8.2.

Les moyens d'inter-verrouillage comportent une barre d'interconnexion (non visible) reliant les deux obturateurs 6.2, 8.2.The inter-locking means comprise an interconnection bar (not visible) connecting the two shutters 6.2, 8.2.

La barre d'interconnexion comporte une première extrémité longitudinale guidée dans une lumière 6.4 de l'obturateur 6.2 et une deuxième extrémité longitudinale guidée dans une lumière 8.4 de l'obturateur 8.2.The interconnection bar has a first longitudinal end guided in a slot 6.4 of the shutter 6.2 and a second longitudinal end guided in a slot 8.4 8.4 of the shutter.

La forme des lumières 6.4, 8.4 est adaptée pour permettre un tel verrouillage.The shape of the lights 6.4, 8.4 is adapted to allow such locking.

La barre d'interconnexion est disposée entre les deux platines avant et arrière, laissant la face avant du dispositif de commande libre.The interconnection bar is disposed between the two front and rear plates, leaving the front face of the control device free.

Ainsi, l'orifice 8.1 et la lumière 56 sont, en l'absence du pignon manivelle 50, occultés par l'obturateur 8.2, qui revient automatiquement en position d'occultation sous l'action du moyen de rappel.Thus, the orifice 8.1 and the light 56 are, in the absence of the crank pinion 50, concealed by the shutter 8.2, which automatically returns to the occultation position under the action of the return means.

Par ailleurs, lorsque le pignon manivelle est en place (figure 7A et 7B), l'obturateur 8.2 est en position ouverte, et l'obturateur 6.2 est verrouillée en position fermée par les moyens d'inter-verrouillage, empêchant l'accès au mécanisme de commande du sectionneur de terre et donc la commutation du sectionneur de terre.Moreover, when the crank sprocket is in place ( Figure 7A and 7B ), the shutter 8.2 is in the open position, and the shutter 6.2 is locked in the closed position by the interlocking means, preventing access to the control mechanism of the earthing switch and therefore the switching of the earthing switch .

Sur la figure 8A, le pignon manivelle 50 a été retiré, mais l'obturateur 8.2 découvre l'orifice 8.1 et la lumière 53, l'obturateur 6.2 ne peut alors être pivoté pour découvrir l'orifice 6.1 et la lumière 55.On the figure 8A , the crank pinion 50 has been removed, but the shutter 8.2 discovers the orifice 8.1 and the light 53, the shutter 6.2 can not then be rotated to reveal the orifice 6.1 and the light 55.

Sur la figure 8B, l'obturateur 8.2 obstrue l'accès à l'orifice 8.1 et à la lumière 53.On the Figure 8B shutter 8.2 obstructs access to aperture 8.1 and to light 53.

Sur la figure 8C, l'obturateur 8.1 est retiré, le levier 72 de commande manuelle est disposé dans l'orifice 8.1 et la lumière 8.2, l'obturateur 6.2 ne peut être pivoté pour découvrir l'orifice 6.1 et la lumière 55.On the Figure 8C , the shutter 8.1 is removed, the manual control lever 72 is disposed in the orifice 8.1 and the light 8.2, the shutter 6.2 can not be rotated to reveal the orifice 6.1 and the light 55.

En outre, il est prévu des moyens pour verrouiller la barre d'interconnexion pour empêcher une fermeture du sectionneur de terre lorsque l'interrupteur est fermé et une fermeture de l'interrupteur lorsque le sectionneur de terre est fermé. Pour cela, ces moyens immobilisent l'obturateur 6.2 pour empêcher l'accès à l'orifice 6.1 et à la lumière 55 lorsque l'interrupteur est fermé et immobilise l'obturateur 8.2 pour empêcher l'accès à l'orifice 8.1 et à la lumière 53 lorsque le sectionneur de terre est fermé.In addition, there are provided means for locking the interconnection bar to prevent closure of the earthing switch when the switch is closed and closing the switch when the earthing switch is closed. For this, these means immobilize the shutter 6.2 to prevent access to the orifice 6.1 and the light 55 when the switch is closed and immobilizes the shutter 8.2 to prevent access to the orifice 8.1 and to the light 53 when the earthing switch is closed.

Par exemple, lorsque l'interrupteur est fermé, le pignon manivelle 50 étant retiré, l'obturateur 8.2 étant alors en position d'obturation, l'obturateur 6.2 est immobilisé et empêche l'accès au mécanisme de commande du sectionneur de terre pour le fermer.For example, when the switch is closed, the crank pinion 50 being removed, the shutter 8.2 then being in the closed position, the shutter 6.2 is immobilized and prevents access to the control mechanism of the earthing switch for the to close.

Le dispositif de commande comporte également des moyens de verrouillage 60 en translation du pignon manivelle 50 afin d'empêcher que celui-ci ne s'échappe de sa position engrenée.The control device also comprises locking means 60 in translation of the crank pinion 50 to prevent it from escaping its engaged position.

Sur les figures 10A à 10C, on peut voir un appareillage moyenne ou haute tension vu de l'extérieur comportant un dispositif de commande selon la présente invention habillé avec une façade avant 76 montée sur le flasque avant 44.On the Figures 10A to 10C , we can see a medium or high voltage device from the outside having a control device according to the present invention dressed with a front panel 76 mounted on the flange before 44.

Sur les figures 10A et 10B, on peut voir les moyens de verrouillage en translation 60 comportant, dans un exemple de réalisation, un capot 62 monté libre en rotation sur une face 50.1 opposée à une face 50.2 en regard de la platine avant 44. Le capot 62 est verrouillable sur le dispositif de commande, par exemple par rotation d'un angle déterminé.On the Figures 10A and 10B , one can see the locking means in translation 60 comprising, in an exemplary embodiment, a cover 62 mounted free to rotate on a face 50.1 opposite to a face 50.2 facing the front plate 44. The cover 62 is lockable on the control device, for example by rotation of a given angle.

Le capot 62 comporte, dans l'exemple représenté, deux paires de pattes 68, 68' diamétralement opposées, faisant saillie radialement du capot 62. Les deux pattes 68, 68' de chaque paire se font face délimitant un espace 69. La patte 68' est destinée à venir au plus près de la façade.The cover 62 comprises, in the example shown, two pairs of tabs 68, 68 'diametrically opposed, projecting radially from the cover 62. The two tabs 68, 68' of each pair face each other defining a space 69. The tab 68 is intended to come closer to the facade.

La façade avant 76 montée sur le flasque avant 44 comporte deux pattes 71 en saillie de la surface principale de la façade 76. Les pattes 71 sont en forme de crochet et sont disposées de manière diamétralement opposée par rapport à l'orifice 8.1 et délimitent respectivement avec la surface principale de la façade 76 un espace 74 pour recevoir la patte 68'. Les pattes 71 sont également particulièrement visibles sur les figures 8A et 8B.The front panel 76 mounted on the front flange 44 has two tabs 71 projecting from the main surface of the facade 76. The tabs 71 are hook-shaped and are arranged diametrically opposite to the orifice 8.1 and delimit respectively with the main surface of the facade 76 a space 74 to receive the tab 68 '. The legs 71 are also particularly visible on the Figures 8A and 8B .

Le verrouillage du capot 62 sur la façade avant s'effectue par rotation d'un angle déterminé autour de l'axe de l'orifice 8.1, faisant pénétrer la patte 68' dans l'espace 74 et la patte 71 dans l'espace 69. Ainsi le capot 62 et le pignon 50 sont immobilisés en translation. Le capot est également immobilisé en rotation mais le montage libre en rotation du capot sur le pignon 50 permet de ne pas gêner la rotation du pignon 50.The locking of the cover 62 on the front panel is effected by rotation of a given angle around the axis of the orifice 8.1, causing the tab 68 'to enter the space 74 and the tab 71 into the space 69. Thus the cover 62 and the pinion 50 are immobilized in translation. The hood is also immobilized in rotation, but the free rotation of the hood on the pinion 50 makes it possible not to hinder the rotation of the pinion 50.

De manière avantageuse, le capot 62 forme un moyen de préhension du pignon manivelle 50, ce qui permet d'éviter un contact direct avec le pignon de manivelle 50 qui peut comporter, notamment de la graisse. De plus l'aspect extérieur de l'appareillage est amélioré.Advantageously, the cover 62 forms a gripping means of the crank pinion 50, which avoids direct contact with the crank pinion 50 which may include, in particular, grease. In addition, the external appearance of the apparatus is improved.

Ainsi le pignon manivelle 50 peut être retiré et remis rapidement sans nécessiter un démontage complet du moto-réducteur.Thus the crank pinion 50 can be removed and delivered quickly without requiring complete disassembly of the geared motor.

Les moyens de verrouillage permettent un montage et un démontage rapide et simple du pignon manivelle 50.The locking means allow quick and easy assembly and disassembly of the crank gear 50.

De manière avantageuse, comme on peut le voir sur les figure 8A et 8B, les pattes 71 sont venues de matière avec un capot 78 du moto réducteur recouvrant celui-ci, ce qui simplifie la fabrication d'un tel appareillage, en réduisant le nombre de pièces à réaliser et à assembler.Advantageously, as can be seen in the figure 8A and 8B , the tabs 71 are integral with a cover 78 of the gear motor covering the latter, which simplifies the manufacture of such an apparatus, reducing the number of parts to be produced and assembled.

La présente invention permet donc, en retirant le pignon 50 en prise avec le mécanisme de commande de découpler cinématiquement le moteur du mécanisme de commande, et donc d'interdire toute manoeuvre électrique du mécanisme de commande.The present invention therefore makes it possible, by withdrawing the pinion gear 50 in engagement with the control mechanism, to cinematically decouple the motor from the control mechanism, and thus to prohibit any electric maneuvering of the control mechanism.

Par ailleurs, son retrait désobture l'orifice 8.1 et la lumière 53, rendant alors accessible le mécanisme de commande pour un actionnement manuel.Moreover, its removal disobures aperture 8.1 and light 53, then rendering accessible control mechanism for manual operation.

Enfin, en l'absence du pignon-manivelle, l'obturateur 8.2 est en position fermée, l'obturateur 6.2 du sectionneur de terre peut être retiré permettant une commutation manuelle du sectionneur de terre, lorsque l'interrupteur est ouvert.Finally, in the absence of the crank-gear, the shutter 8.2 is in the closed position, the shutter 6.2 of the earthing switch can be removed allowing manual switching of the earthing switch, when the switch is open.

De manière avantageuse, le moto-réducteur se trouve dans son ensemble, en face avant du dispositif de commande, rendant le pignon manivelle plus accessible et son retrait plus aisé. En outre, ceci permet de simplifier la maintenance du moto-réducteur.Advantageously, the geared motor is in its entirety, in front of the control device, making the crank pinion more accessible and removal easier. In addition, this simplifies maintenance of the geared motor.

On pourrait prévoir de disposer le moteur électrique en face arrière et de ne placer que le pignon manivelle 50 en face avant du dispositif de commande.It could be arranged to have the electric motor on the rear face and to place only the crank pinion 50 on the front face of the control device.

Le retrait du pignon manivelle permet ainsi d'interrompre la liaison mécanique entre le moteur et l'interrupteur. Il n'y a alors plus aucun risque de commutation accidentelle de l'interrupteur alors que le sectionneur de terre est fermé.The removal of the crank pinion thus makes it possible to interrupt the mechanical connection between the motor and the switch. There is then no risk of accidental switching of the switch while the earthing switch is closed.

Sur la figure 8C, le retrait du pignon manivelle 50 et la mise en place de l'obturateur 8.2 sur l'orifice 8.1 et la lumière 53, permet la mise en place d'un levier 72 pour réaliser un actionnement manuelOn the Figure 8C , the withdrawal of the crank gear 50 and the introduction of the shutter 8.2 on the orifice 8.1 and the light 53, allows the establishment of a lever 72 to perform manual actuation

Le dispositif de commande comporte également des capteurs, par exemple des micro-contacts, actionnés par des éléments en mouvement de la chaîne de transmission de puissance, par exemple du pignon manivelle 50 ou de la chaîne indicatrice de la position de l'interrupteur ou du sectionneur de terre, par exemple la barre d'interconnexion et/ou la présence du capot amovible. Les informations fournies par ces micro-contacts permettent de commander l'alimentation du moteur et d'arrêter celle-ci lorsque l'interrupteur ou le sectionneur de terre a atteint la position désirée.The control device also comprises sensors, for example micro-contacts, actuated by moving elements of the power transmission chain, for example pinion crank 50 or chain indicating the position of the switch or the earthing switch, for example the interconnection bar and / or the presence of the removable cover. The information provided by these micro-contacts allows to control the power supply of the motor and to stop it when the switch or the earthing switch has reached the desired position.

Par ailleurs, les micro-contacts assurent une fonction de sécurité, puisqu'ils informent une unité de commande que le sectionneur de terre est fermé, l'interrupteur ayant été ouvert au préalable. L'unité de commande court-circuite alors le moteur électrique pour éviter une fermeture de l'interrupteurIn addition, the microswitches provide a safety function, since they inform a control unit that the earthing switch is closed, the switch having been opened beforehand. The control unit then bypasses the electric motor to prevent the switch from closing

Le court-circuit provoque également la fusion d'un fusible protégeant le moteur, afin de respecter une norme prévoyant une fusion d'un fusible protégeant le moteur en moins d'une seconde.The short circuit also fuses a fuse to protect the motor, to meet a standard that fuses a fuse protecting the motor in less than one second.

De manière particulièrement intéressante, on observe que cette fusion est beaucoup plus rapide que dans les circuits de l'état de la technique, puisque cette fusion est produite par un court-circuit et non une surcharge du moteur. Cependant, il est à noter que, selon la présente invention, la fusion du fusible n'a pas pour effet de protéger le moteur, puisque celui-ci ne force pas. En effet le pignon manivelle étant retiré le moteur tourne dans le vide et n'est pas bloqué, il s'agit juste d'un artifice pour respecter la norme.In a particularly interesting way, it is observed that this fusion is much faster than in the circuits of the state of the art, since this fusion is produced by a short circuit and not an overload of the engine. However, it should be noted that, according to the present invention, the fusion of the fuse does not have the effect of protecting the motor, since it does not force. Indeed the crank pinion is removed the engine runs in the vacuum and is not blocked, it is just a device to meet the standard.

On peut également prévoir d'actionneur le mécanisme de commande du sectionneur de terre de manière motorisée en utilisant un dispositif de commande motorisé similaire à celui de la présente invention pour l'actionnement de l'interrupteur de terre.It is also possible to provide an actuator for the control mechanism of the earthing switch of motorized manner using a motorized control device similar to that of the present invention for actuating the earth switch.

Nous allons maintenant expliquer le fonctionnement du mécanisme de commande selon la présente invention dans le cas d'une ouverture de l'interrupteur et d'une fermeture manuelle du sectionneur de terre.We will now explain the operation of the control mechanism according to the present invention in the case of an opening of the switch and a manual closing of the earthing switch.

En fonctionnement motorisé (figure 7A), le pignon manivelle 50 est en place sur la platine avant 44 entre l'arbre 8 et le moteur, l'obturateur 8.2 est en position retirée, dégageant l'ouverture 8.1.In motorized operation ( Figure 7A ), the crank pinion 50 is in place on the front plate 44 between the shaft 8 and the motor, the shutter 8.2 is in the withdrawn position, disengaging the opening 8.1.

Le pignon manivelle 50 est engrené par la roue dentée 52 reliée à l'arbre du moteur et est en prise avec le tumbler d'interrupteur. L'obturateur 8.2 est ouvert.The crank gear 50 is engaged by the gear 52 connected to the motor shaft and is engaged with the switch tumbler. The shutter 8.2 is open.

Une commande du moteur provoque la rotation du pignon manivelle 50 et la commutation de l'interrupteur, celui-ci s'ouvre.A control of the motor causes the rotation of the crank pinion 50 and the switching of the switch, the latter opens.

La commutation du sectionneur de terre s'effectue manuellement à l'aide d'un levier, dont une extrémité est destinée à pénétrer dans l'ouverture 6.1.Switching of the earthing switch is carried out manually using a lever, one end of which is intended to penetrate the opening 6.1.

Or, tant que l'obturateur 8.2 de l'interrupteur est en position dégagée, du fait de la présence du pignon manivelle 50 et des moyens d'inter-verrouillage, l'obturateur 6.2 du sectionneur de terre ne peut pas être déplacé pour dégager l'ouverture 6.1.However, as long as the shutter 8.2 of the switch is in the disengaged position, because of the presence of the crank pinion 50 and interlocking means, the shutter 6.2 of the earthing switch can not be moved to clear the opening 6.1.

L'opérateur doit donc retirer un élément du réducteur, dans l'exemple avantageux décrit ci-dessus il s'agit du pignon manivelle 50. Pour cela il fait tourner le capot 62 sur lui-même pour écarter les pattes 68 de la patte 71 et tirer sur le capot 62 pour extraire le pignon manivelle 50. Dés le retrait du pignon manivelle 50, l'obturateur 8.2 est rappelé en position et obture l'ouverture 8.1.The operator must therefore remove an element of the gearbox, in the advantageous example described above it is the crank gear 50. For this it makes turn the cover 62 on itself to spread the tabs 68 of the tab 71 and pull on the cover 62 to extract the crank pinion 50. On removal of the crank pinion 50, the shutter 8.2 is recalled in position and closes the opening 8.1.

L'opérateur peut ensuite déplacer l'obturateur 6.2, mettre en place le levier et fermer le sectionneur de terre. Il n'y a alors aucun risque de fermeture de l'interrupteur par une mise en route du moteur, par exemple si un ordre intempestif enclenche la mise en route du moteur du fait d'un micro-contact de position défaillant (ce qui est un cas prévu par une norme), puisque la chaîne cinématique de transmission de puissance entre le moteur et l'arbre du mécanisme de commande de l'interrupteur est rompue.The operator can then move the shutter 6.2, set up the lever and close the earthing switch. There is then no risk of closing the switch by starting the engine, for example if a nuisance command triggers the start of the engine due to a faulty micro-contact position (which is a case provided by a standard), since the kinematic chain of power transmission between the motor and the shaft of the control mechanism of the switch is broken.

En outre, l'opérateur ne peut pas ensuite fermer l'interrupteur tant que le sectionneur de terre est fermé, puisque les moyens d'inter-verrouillage empêchent le retrait de l'obturateur 8.2 de l'interrupteur. Il ne peut ainsi ni effectuer une manoeuvre manuelle, ni ré-engrener la motorisation. Le moteur est également mis en court-circuit par la détection de la fermeture du sectionneur de terre au moyen des micro-contacts.In addition, the operator can not then close the switch as the earthing switch is closed, since the inter-locking means prevent the removal of the shutter 8.2 of the switch. It can thus neither perform a manual operation, nor re-mesh the engine. The motor is also short-circuited by detecting the closing of the earthing switch by means of the microswitches.

Ainsi les commandes de l'interrupteur et du sectionneur de terre sont parfaitement sécurisées en cas de défaillance du système de protection usuel.Thus the controls of the switch and the earthing switch are perfectly secure in case of failure of the usual protection system.

En cas de manoeuvre électrique interrompue, l'opérateur procède comme précédemment, de même en cas d'actionnement entièrement manuel.In case of interrupted electric maneuver, the operator proceeds as before, the same in case of fully manual operation.

Dans la configuration où la commande du sectionneur de terre est également motorisée, le fonctionnement est identique à celui dans le cas d'une commande manuelle du sectionneur de terre, la mise en place d'un pignon manivelle remplace celle d'un levier. Il est prévu, pour pouvoir commuter l'interrupteur en ouverture ou en fermeture, de retirer le pignon manivelle permettant un actionnement électrique du sectionneur de terre, pour pouvoir déplacer l'obturateur 8.2 afin d'avoir accès au mécanisme de commande de l'interrupteur et mettre en place le pignon manivelle 50 ou un levier.In the configuration where the control of the earthing switch is also motorized, the operation is identical to that in the case of a manual control of the earthing switch, the setting up of a crank pinion replaces that of a lever. It is planned, in order to be able to switch the switch on opening or closing, to remove the crank pinion enabling electrical actuation of the earthing switch, in order to be able to move the shutter 8.2 in order to have access to the control mechanism of the switch. and set up the crank sprocket 50 or lever.

La présente invention s'applique principalement aux postes de distribution moyenne ou haute tension.The present invention applies mainly to medium or high voltage distribution stations.
