Description

La présente invention se rapporte à un dispositif d'actionnement d'un appareil électrique, en particulier d'un sectionneur ou d'un sectionneur de mise à la terre haute tension.The present invention relates to a device for actuating an electrical appliance, in particular a disconnector or high earthing switch voltage.

Elle concerne plus précisément un dispositif d'actionnement d'un appareil électrique, en particulier d'un sectionneur ou d'un sectionneur de mise à la terre haute tension, comportant dans un boítier de commande un dispositif d'entraínement par rotation des contacts de l'appareil haute tension et un circuit de pilotage comportant des contacts dit de fin de course associés aux contacts de l'appareil.It relates more precisely to a device for actuating an electrical appliance, in particular a disconnector or high earthing switch voltage, comprising in a control box a device for rotating the contacts of the high-voltage device and a control circuit comprising so-called limit switch contacts associated with device contacts.

Les sectionneurs haute tension, ainsi que les sectionneurs de terre sont de façon générale actionnés électriquement grâce à un moteur électrique mis en fonction à partir d'une armoire de commande locale et associé à un circuit de pilotage comportant des contacts commandés par un circuit de signalisation de position associé aux contacts de l'appareil.High voltage disconnectors, as well as earthing switches are generally operated electrically thanks to an electric motor switched on from a local control cabinet and associated with a control circuit comprising contacts controlled by a position signaling circuit associated with the the device.

L'ordre d'ouverture ou de fermeture est transmis de cette armoire et l'arrêt du moteur est assuré par les contacts du circuit de pilotage.The order to open or close is sent from this cabinet and the engine is stopped by the pilot circuit contacts.

De façon classique, ce moteur électrique d'actionnement est fixe à l'intérieur d'un boítier de commande comprenant une connexion possible pour une manivelle de secours en cas de panne du moteur, de son alimentation ou de défaut de la tension de pilotage des contacteurs de commande. Cette connexion mécanique assure, lorsque la manivelle est connectée, la déconnexion électrique du moteur.Conventionally, this electric motor actuator is fixed inside a housing command including a possible connection for a emergency crank in case of engine failure, sound supply or fault of the control voltage of the control contactors. This mechanical connection ensures, when the crank is connected, disconnection electric motor.

Cette manoeuvre manuelle par manivelle pose des problèmes de deux type. This manual crank operation poses problems of two types.

Premièrement, la vitesse de rotation de la manivelle ne peut être imposée et peut donc être excessivement lente ou rapide. Aucune garantie de performance électrique du sectionneur ne peut donc être donnée, en particulier lors d'une opération de transfert en charge avec des postes à deux jeux de barres par exemple. Par ailleurs, les contacts de signalisation de position qui doivent être à action positive pour des raisons de fiabilité peuvent s'ouvrir avec une vitesse de séparation des contacts trop lente dans le cas de coupure de courants importants de nature selfique. Enfin, lors de l'ouverture des contacts du sectionneur, si la vitesse de séparation des contacts est trop lente, un arc sollicite ces contacts pendant un temps trop long et les endommage.First, the rotation speed of the crank cannot be imposed and can therefore be excessively slow or fast. No guarantee of electrical performance disconnector cannot therefore be given, in particular during of a transfer operation in charge with positions at two busbars for example. In addition, the contacts position indicators which must be in action positive for reliability reasons can open with contact separation speed too slow in the case of interruption of large currents of selfic nature. Finally, when opening the switch contacts, if contact separation speed is too slow, an arc requests these contacts for too long a time and the damages.

Deuxièmement, la manoeuvre complète de fermeture ou d'ouverture n'est pas garantie et l'arrêt de la manoeuvre peut se faire par choc des butées mécaniques éventuellement en pleine vitesse, ce qui est préjudiciable au bon état des contacts. Ceci est particulièrement problématique dans le cas d'appareils blindés, c'est-à-dire sous enveloppe métallique, où les contacts sont cachés et la manoeuvre doit se faire à l'aveugle.Second, the complete closing maneuver or opening is not guaranteed and stopping the maneuver can be done by shock of mechanical stops possibly at full speed, which is detrimental to the good condition of contacts. This is particularly problematic in the case of shielded devices, i.e. in envelopes metallic, where the contacts are hidden and the operation must be done blind.

Pour résoudre ces problèmes, l'invention propose de remplacer la manivelle par un moteur électrique portatif à alimentation autonome équipé d'un agencement de liaison mécanique avec le dispositif d'entraínement par rotation et pourvu d'un dispositif de connexion électrique au circuit de pilotage.To solve these problems, the invention proposes replace the crank with a portable electric motor autonomous power supply equipped with a connection arrangement mechanical with the rotary drive and provided with a device for electrical connection to the circuit steering.

La vitesse de ce moteur portatif étant connue et constante, le premier type de problèmes est résolu. Grâce à sa liaison avec le circuit de pilotage, le moteur portatif peut être arrêté automatiquement à la fin des opérations d'ouverture et de fermeture, ce qui résout le second type de problème. The speed of this portable motor being known and constant, the first type of problem is solved. Thanks to its connection to the control circuit, the portable engine can be stopped automatically at the end of operations opening and closing, which solves the second type of problem.

Ledit circuit de commande est actionné, de préférence, par l'intermédiaire de deux boutons poussoirs et assure la rotation dans un sens ou dans l'autre sens du moteur .Said control circuit is preferably actuated via two push buttons and ensures rotation in one direction or the other direction of the motor.

Le dispositif peut comporter également une liaison à un relais de verrouillage destiné à être connecté audit connecteur et un pontage de détermination du sens de la manoeuvre destiné à être connecté audit connecteur.The device may also include a connection to a locking relay intended to be connected to said audit connector and jumper to determine the direction of the operation intended to be connected to said connector.

Selon le mode de réalisation préféré, il constitue un dispositif de secours d'actionnement de l'appareil électrique en cas de malfonctionnement d'un dispositif d'actionnement normal comportant un moteur électrique fixe associé audit boítier.According to the preferred embodiment, it constitutes a emergency device actuation device electric in the event of a device malfunction normal actuation with a fixed electric motor associated with said housing.

En cas de manoeuvre de l'appareil, l'ordre de fonctionnement est transmis de l'armoire de commande locale au moteur 40 et les contacts 5C, 6C sont manoeuvrés en fin d'ouverture ou fermeture des contacts de l'appareil pour arrêter le fonctionnement du moteur 40.If the device is operated, the order of operation is transmitted from the local control cabinet at motor 40 and contacts 5C, 6C are operated at the end opening or closing the device contacts for stop engine 40.

Selon l'invention, le circuit de pilotage est tronçonné et en partie contenu dans un connecteur 8 étanche et démontable par l'intermédiaire de connexions 42. Ce connecteur 8 assure, lorsqu'il est monté, la continuité du circuit de pilotage et la connexion des contacts 5C, 6C à l'armoire de commande locale.According to the invention, the control circuit is sectioned and partly contained in a sealed connector 8 and removable via connections 42. This connector 8 ensures, when mounted, the continuity of control circuit and connection of contacts 5C, 6C to the local control cabinet.

Lors d'une panne du moteur d'actionnement 40, de son alimentation ou de défaut de la tension de pilotage des contacteurs de commande, le connecteur 8 est retiré comme représenté sur les figures 2A et 2B. Le circuit de pilotage est alors ouvert et déconnecté de l'armoire de commande locale.When the actuating motor 40 fails, its supply or fault of the control voltage of the control switches, connector 8 is removed as shown in Figures 2A and 2B. The driving circuit is then opened and disconnected from the control cabinet local.

Est alors mis en place le dispositif d'actionnement conforme à l'invention en tant que dispositif de secours, comme représenté sur les figures 3A et 3B.The actuation device is then put in place according to the invention as a backup device, as shown in Figures 3A and 3B.

Ce dispositif comporte un moteur électrique 20 portatif à alimentation 23 autonome, avantageusement une batterie, équipé d'un agencement de liaison mécanique 22 avec le dispositif d'entraínement par rotation 15 et pourvu d'un dispositif de connexion électrique 25 aux connexions libérées 42.This device comprises an electric motor 20 portable power supply 23 autonomous, preferably a battery, equipped with a mechanical connection arrangement 22 with the rotary drive device 15 and provided an electrical connection device 25 to the connections released 42.

Ce circuit de commande 24 comporte un ensemble d'interrupteurs, dont deux 25, 26 sont fermés sous l'effet d'un premier bouton-poussoir 29 destiné à l'ouverture et dont les deux autres 27, 28 sont fermés sous l'effet d'un second bouton-poussoir 30 destiné à la fermeture. Ce circuit de commande 24 à branches parallèles, du même type que celui du moteur 40, permet l'inversion du sens de rotation selon le bouton-poussoir actionné.This control circuit 24 includes a set switches, two of which 25, 26 are closed under the effect a first push button 29 intended for opening and of which the other two 27, 28 are closed under the effect of a second push button 30 intended for closing. This circuit 24 with parallel branches, of the same type as that motor 40, allows the reversal of the direction of rotation according to the button pressed.

Sont intercalés entre lui et le moteur 20, grâce au connecteur 25:

  • le contact 5C relié aux interrupteurs 25 et 26 du circuit de commande 24,
  • le contact 6C relié aux interrupteurs 27 et 28 du circuit de commande 24,
  • un interrupteur 31 optionnel actionné par un relais de verrouillage 32 assurant l'autorisation de la manoeuvre et connecté au connexions 9 et 10,
  • un pontage 33 reliant les connexions 11 à 14, propre au mécanisme de commande 2 et donc à l'appareil et assurant la rotation dans le sens correct du moteur 20.
Are interposed between it and the motor 20, thanks to the connector 25:
  • the contact 5C connected to the switches 25 and 26 of the control circuit 24,
  • the contact 6C connected to the switches 27 and 28 of the control circuit 24,
  • an optional switch 31 actuated by a locking relay 32 ensuring authorization of the operation and connected to connections 9 and 10,
  • a bridging 33 connecting the connections 11 to 14, specific to the control mechanism 2 and therefore to the apparatus and ensuring rotation in the correct direction of the motor 20.

Le moteur portatif 20 est donc piloté, de façon semblable au moteur 40, par les contacts 5C et 6C de le circuit de pilotage 4. Une fois les contacts de l'appareil totalement fermés ou totalement ouverts, l'alimentation du moteur portatif 20 est arrêtée et la manoeuvre interrompue.The portable motor 20 is therefore controlled, so similar to motor 40, through contacts 5C and 6C of the control circuit 4. Once the device contacts fully closed or fully open, the portable motor 20 is stopped and the maneuver interrupted.

Le relais de verrouillage 32 disposé dans l'armoire de commande locale 1 peut être connecté grâce aux connexions 9 et 10 en série au contact précédent 5C ou 6C. Ce relais assure une sécurité d'autorisation de la manoeuvre. Ceci interdit toute fausse manoeuvre du type fermeture de l'appareil sous tension ou en charge.The locking relay 32 located in the cabinet local control 1 can be connected using connections 9 and 10 in series at the previous contact 5C or 6C. This relay provides security for authorization of the maneuver. This prohibits any false operation of the closing type with the power on or on.

Le pontage 33 détermine le sens de rotation d'ouverture ou de fermeture. En effet, ce sens peut varier selon le mécanisme de commande 2 et il est ainsi possible d'équiper le dispositif de secours des deux boutons poussoirs 29, 30 indiquant simplement et directement pour le bouton 29 "pour ouvrir" et pour le bouton 30 "pour fermer". Le pontage 33 peut donc être une liaison continue ou un inverseur de sens. L'opérateur n'a donc pas à se soucier du sens de rotation effectif de fermeture ou d'ouverture de l'appareil.Bridging 33 determines the direction of rotation opening or closing. Indeed, this meaning can vary according to control mechanism 2 and it is thus possible to equip the emergency device with two buttons pushers 29, 30 simply and directly indicating for the button 29 "to open" and for button 30 "to close". Bridging 33 can therefore be a continuous link or a direction reverser. The operator therefore does not have to worry about effective direction of rotation for closing or opening the device.
