Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un système d'actionnement d'une ampoule à vide dans le but d'ouvrir un circuit électrique dans un appareil de connexion électrique de moyenne tension ou haute tension, c'est-à-dire un appareil opérant à une tension supérieure à 1000V.The present invention relates to a system for actuating a vacuum interrupter for the purpose of opening an electrical circuit in a medium voltage or high voltage electrical connection apparatus, that is to say an apparatus operating at a voltage greater than 1000V.

L'invention concerne également un appareil de connexion électrique comportant un tel système d'actionnement pour au moins une de ses phases. Dans le présent document, le terme appareil de connexion électrique regroupe indifféremment plusieurs types d'appareils électriques comme un interrupteur, un disjoncteur, un contacteur, un interrupteur fusible, un recloser, etc.The invention also relates to an electrical connection apparatus comprising such an actuating system for at least one of its phases. In this document, the term electrical connection apparatus includes indifferently several types of electrical devices such as a switch, a circuit breaker, a contactor, a fuse switch, a recloser, etc.

Etat de la techniqueState of the art

Un appareil de connexion électrique moyenne tension ou haute tension du type de celui décrit dans le document EP2182536 comporte une ampoule à vide qui est placée non pas dans le circuit principal comprenant l'interrupteur principal d'une phase de l'appareil, mais dans une dérivation en parallèle de cet interrupteur principal. En fonctionnement normal, lorsque l'interrupteur principal est fermé, il ne passe aucun courant dans l'ampoule à vide. Celle-ci n'est sollicitée que durant une opération d'ouverture du circuit principal, à l'aide d'un mécanisme d'ouverture de l'interrupteur principal qui permet d'abord de basculer le courant progressivement du circuit principal vers la dérivation, ce qui permet d'ouvrir l'interrupteur principal pendant que le courant passe intégralement dans l'ampoule à vide. Celle-ci est ensuite ouverte à son tour par le mécanisme d'ouverture. On évite ainsi l'apparition d'un arc électrique de coupure au niveau de l'interrupteur principal lors de l'opération d'ouverture.A medium voltage or high voltage electrical connection device of the type described in the document EP2182536 comprises a vacuum interrupter which is placed not in the main circuit comprising the main switch of a phase of the apparatus, but in a branch in parallel of this main switch. In normal operation, when the main switch is closed, no current flows into the vacuum interrupter. It is requested only during an opening operation of the main circuit, with the aid of a mechanism for opening the main switch which first allows the flow to be switched gradually from the main circuit to the bypass. , which opens the main switch while the current flows completely into the vacuum bulb. This is then opened in turn by the opening mechanism. This avoids the occurrence of an electric arc cut at the main switch during the opening operation.

Grâce à cette architecture, l'ampoule à vide reçoit un courant uniquement durant la phase d'ouverture du circuit principal de phase, et pas en fonctionnement normal. De plus, l'ampoule n'est pas sollicitée durant une opération de fermeture du circuit principal et elle n'a pas à supporter non plus un éventuel courant de court-circuit. Elle doit juste être capable de supporter une tension transitoire de rétablissement (Transient Recovery Voltage-TRV) après la coupure du courant dans le circuit principal.Thanks to this architecture, the vacuum bulb receives a current only during the opening phase of the main phase circuit, and not in normal operation. In addition, the bulb is not solicited during a closing operation of the main circuit and it does not have to support any short-circuit current. It must just be able to withstand a Transient Recovery Voltage-TRV after the main circuit has been cut off.

Il en résulte que l'ampoule à vide peut avantageusement être simplifiée et conçue d'une taille bien inférieure par rapport à une architecture classique dans laquelle l'ampoule à vide est placée dans le circuit principal de l'appareil de connexion électrique.As a result, the vacuum can advantageously be simplified and designed much smaller in size than a conventional architecture in which the vacuum interrupter is placed in the main circuit of the electrical connection apparatus.

Cependant, le mécanisme d'ouverture qui permet de basculer progressivement le courant du circuit principal vers la dérivation puis d'ouvrir ensuite l'ampoule à vide placée dans la dérivation doit être très précis et reproductible pour s'assurer d'une part que, pour chaque phase, l'ouverture de l'ampoule à vide est bien effectuée seulement une fois que l'interrupteur principal est déjà suffisamment ouvert pour ne pas risquer d'arc électrique sur l'interrupteur principal, et d'autre part que les ampoules à vide des différentes phases de l'appareil sont bien ouvertes simultanément.However, the opening mechanism which makes it possible to gradually switch the current of the main circuit to the bypass and then to open the vacuum bulb placed in the bypass must be very precise and reproducible to ensure on the one hand that, for each phase, the opening of the vacuum interrupter is performed only once the main switch is already open enough to avoid arcing the main switch, and on the other hand that the bulbs empty the different phases of the device are open simultaneously.

Les documents US2655930 et EP1139367 décrivent des appareils de connexion électrique ayant un mécanisme comportant un écrou de réglage qui sert à modifier la pression de contacts d'une ampoule à vide.The documents US2655930 and EP1139367 disclose electrical connection apparatus having a mechanism having an adjustment nut for changing the contact pressure of a vacuum bulb.

Les documents US8471186 et US8466835 décrivent des systèmes d'ajustement mécaniques relativement complexes pour l'ajustement entre les contacts d'un interrupteur d'un appareillage électrique.The documents US8471186 and US8466835 describe relatively complex mechanical adjustment systems for adjustment between the contacts of a switch of an electrical apparatus.

Un des buts de l'invention est de trouver un système simple, fiable et économique qui permette à la fois d'effectuer le mouvement d'ouverture d'une ampoule à vide et de pouvoir régler facilement et précisément l'instant de déclenchement de ce mouvement d'ouverture.One of the aims of the invention is to find a simple, reliable and economical system which makes it possible both to carry out the opening movement of a vacuum interrupter and to be able to easily and precisely adjust the moment of triggering of this opening movement.

Pour effectuer le mouvement inverse de fermeture, c'est-à-dire passer de la position ouverte à la position fermée, l'électrode mobile 2 peut par exemple être entraînée par un ressort de rappel non représenté sur les figures.The movable electrode 2 of the vacuum bottle is driven by an actuating system that allows in particular to make an opening movement of the vacuum bottle 1, that is to say to move from the position closed in the open position. To perform the reverse closing movement, that is to say move from the open position to the closed position, the movable electrode 2 may for example be driven by a return spring not shown in the figures.

Le système d'actionnement selon l'invention comporte un dispositif d'entraînement comprenant une palette 25, mobile en rotation autour d'un axe transversal 26, et un anneau 20 qui est solidaire de la palette 25 par l'intermédiaire de deux bielles latérales 21. Durant une opération d'ouverture d'un interrupteur principal de phase de l'appareil de connexion électrique, ce dispositif d'entraînement se déplace sous l'action d'un mécanisme d'ouverture de l'interrupteur principal de phase (non représenté sur les figures) qui agit sur la palette 25. Les différentes figures montrent ainsi une flèche schématisant la poussée exercée par le mécanisme d'ouverture sur la palette 25 et sur les bielles 21 durant le mouvement d'ouverture de l'ampoule à vide 1.The actuating system according to the invention comprises a driving device comprising a pallet 25, mobile in rotation about a transverse axis 26, and a ring 20 which is secured to the pallet 25 by means of two lateral rods 21. During an operation of opening a main phase switch of the electrical connection apparatus, this driving device moves under the action of a mechanism for opening the main phase switch (no represented in the figures) which acts on the pallet 25. The various figures thus show an arrow schematically the thrust exerted by the opening mechanism on the pallet 25 and on the connecting rods 21 during the opening movement of the vacuum interrupter 1.

Dans le cas d'un appareil de connexion électrique multiphases (par exemple triphasé) ayant donc un interrupteur principal pour chacune des phases, l'appareil comporte préférentiellement une ampoule à vide en dérivation de chaque interrupteur principal et donc un système d'actionnement de l'ampoule à vide pour chaque phase. Le mécanisme d'ouverture agissant sur les systèmes d'actionnement d'un tel appareil peut cependant être commun pour tous les interrupteurs principaux de l'appareil.In the case of a multiphase electrical connection apparatus (for example three-phase) thus having a main switch for each of the phases, the apparatus preferably comprises a vacuum interrupter of each switch main and therefore a system of actuation of the vacuum bulb for each phase. The opening mechanism acting on the actuating systems of such an apparatus may, however, be common to all main switches of the apparatus.

Le système d'actionnement comporte également un écrou de réglage 10 qui est lié à l'électrode mobile 2 et qui est susceptible de rotation pour ajuster sa position par rapport à l'électrode mobile 2. Durant le mouvement d'ouverture, l'anneau 20 du dispositif d'entraînement vient buter contre un rebord 11 de l'écrou de réglage 10 de façon à pouvoir entraîner l'électrode mobile 2 vers la position ouverte de l'ampoule à vide 1.The actuating system also comprises an adjusting nut 10 which is connected to the movable electrode 2 and which is rotatable to adjust its position relative to the moving electrode 2. During the opening movement, the ring 20 of the drive device abuts against a flange 11 of the adjusting nut 10 so as to drive the movable electrode 2 to the open position of the vacuum bottle 1.

Avantageusement, l'écrou de réglage 10 remplit donc plusieurs fonctions ce qui rend la solution simple et économique à mettre en oeuvre. Il sert à transmettre le mouvement du mécanisme d'ouverture de l'appareil de connexion vers l'électrode mobile 2 de l'ampoule à vide 1. Il sert également à régler l'instant précis où les électrodes fixe 3 et mobile 2 de l'ampoule à vide vont se séparer en jouant sur l'ajustement entre l'écrou de réglage 10 et l'électrode mobile 2. En effet, en tournant légèrement l'écrou de réglage 10 dans un sens ou dans un autre, on fait varier la distance entre l'anneau 20 et le rebord 11 de l'écrou de réglage 10, et donc on fait varier l'instant où l'électrode mobile 2 va commencer son mouvement d'ouverture.Advantageously, the adjusting nut 10 thus fulfills several functions, which makes the solution simple and economical to implement. It serves to transmit the movement of the opening mechanism of the connection apparatus to the moving electrode 2 of the vacuum interrupter 1. It also serves to regulate the precise instant when the fixed electrodes 3 and mobile 2 of the Vacuum bulb will separate by playing on the adjustment between the adjusting nut 10 and the moving electrode 2. Indeed, by slightly turning the adjusting nut 10 in one direction or another, is varied the distance between the ring 20 and the flange 11 of the adjusting nut 10, and therefore the moment when the moving electrode 2 will start its opening movement is varied.

Avantageusement, l'écrou de réglage 10 sert ainsi à régler la course d'ouverture de l'ampoule à vide 1 et ne modifie pas la pression de contact.Advantageously, the adjusting nut 10 thus serves to adjust the opening stroke of the vacuum bottle 1 and does not change the contact pressure.

Selon le premier mode de réalisation des figures 1 et 2, la liaison entre l'écrou de réglage 10 et l'électrode mobile 2 est faite de la façon suivante : le système d'actionnement comporte une bague filetée 15, dotée d'un filetage extérieur coopérant avec un filetage intérieur de l'écrou de réglage 10 pour ajuster le réglage de l'écrou de réglage 10 par rapport à l'électrode mobile 2, et comporte un manchon 18 introduit à l'intérieur de la bague filetée 15 et fixé à l'électrode mobile.According to the first embodiment of the Figures 1 and 2 , the connection between the adjusting nut 10 and the moving electrode 2 is made in the following manner: the actuating system comprises a threaded ring 15, provided with an external thread cooperating with an internal thread of the nut of setting 10 to adjust the adjustment of the adjusting nut 10 relative to the movable electrode 2, and includes a sleeve 18 inserted inside the threaded ring 15 and attached to the movable electrode.

Le manchon 18 est fixé à l'électrode mobile 2 par une vis de fixation transverse 19 qui traverse le manchon 18 et l'électrode mobile 2. Avantageusement, la vis de fixation 19 est aussi utilisée pour fixer un câble conducteur (non représenté sur les figures) qui raccorde électriquement l'électrode mobile 2 de l'ampoule à vide 1 à l'appareil de connexion électrique. De plus, elle permet également de coincer la bague filetée 15 entre le rebord du manchon 18 et la vis 19.The sleeve 18 is fixed to the moving electrode 2 by a transverse fixing screw 19 which passes through the sleeve 18 and the moving electrode 2. Advantageously, the fixing screw 19 is also used to fix a conductive cable (not shown on the FIG. figures) which electrically connects the movable electrode 2 of the vacuum bulb 1 to the electrical connection apparatus. In addition, it also makes it possible to wedge the threaded ring 15 between the rim of the sleeve 18 and the screw 19.

La bague filetée 15 est agencée pour pouvoir entraîner le manchon 18 durant le mouvement d'ouverture, par exemple grâce à leur rebord respectif comme le montre la figure 2, mais elle n'est pas fixée au manchon 18. En particulier, la bague filetée 15 est avantageusement libre en rotation par rapport au manchon 18, ce qui évite tout risque de torsion de l'électrode mobile 2 et donc du soufflet d'étanchéité 4 de l'ampoule à vide, lors de la rotation de l'écrou de réglage 10.The threaded ring 15 is arranged to be able to drive the sleeve 18 during the opening movement, for example by virtue of their respective rim as shown in FIG. figure 2 , but it is not fixed to the sleeve 18. In particular, the threaded ring 15 is advantageously free in rotation with respect to the sleeve 18, which avoids any risk of torsion of the moving electrode 2 and therefore of the sealing bellows 4 of the vacuum bulb, when turning the adjusting nut 10.

Le système d'actionnement comporte en outre un dispositif de blocage qui permet de figer la position de l'écrou de réglage 10 par rapport à l'électrode mobile 2, une fois le réglage effectué. Le dispositif de blocage comprend une vis de blocage 12, par exemple de type vis pointeau qui, une fois serrée, permet d'empêcher la rotation de l'écrou de réglage 10 par rapport à la bague filetée 15, et donc de bloquer sa position relative par rapport à l'électrode mobile 2.The actuating system further comprises a locking device which makes it possible to freeze the position of the adjusting nut 10 relative to the moving electrode 2, once the adjustment has been made. The locking device comprises a locking screw 12, for example of the needle screw which, once tightened, makes it possible to prevent the rotation of the adjusting nut 10 with respect to the threaded ring 15, and thus to block its position. relative to the moving electrode 2.

Les figures 3 et 4 montrent un deuxième mode de réalisation de l'invention. Dans ce mode de réalisation, l'appareil de connexion électrique comporte une ampoule à vide 1 identique à celle décrite précédemment et montée dans un support 5.The Figures 3 and 4 show a second embodiment of the invention. In this embodiment, the electrical connection apparatus comprises a vacuum interrupter 1 identical to that previously described and mounted in a support 5.

Comme pour les figures 1 et 2, l'électrode mobile 2 de l'ampoule à vide est entraînée par un système d'actionnement pour effectuer un mouvement d'ouverture. Pour effectuer le mouvement inverse de fermeture et passer de la position ouverte à la position fermée, l'électrode mobile 2 peut de la même façon être entraînée par exemple par un ressort de rappel non représenté sur les figures.As for Figures 1 and 2 the moving electrode 2 of the vacuum bulb is driven by an actuating system to effect an opening movement. To perform the reverse closing movement and move from the open position to the closed position, the movable electrode 2 can likewise be driven for example by a return spring not shown in the figures.

Comme pour les figures 1 et 2, le système d'actionnement comporte un dispositif d'entraînement comprenant une palette 125, mobile en rotation autour d'un axe transversal 126, et un anneau 120 qui est actionné par la palette 125 par l'intermédiaire de deux bielles latérales 121. Durant une opération d'ouverture du circuit principal d'une phase de l'appareil de connexion électrique, ce dispositif d'entraînement se déplace sous l'action du mécanisme d'ouverture de l'interrupteur principal de phase (non représenté sur les figures) qui agit sur la palette 125.As for Figures 1 and 2 , the actuating system comprises a driving device comprising a pallet 125, rotatable about a transverse axis 126, and a ring 120 which is actuated by the pallet 125 by means of two lateral rods 121. During an opening operation of the main circuit of a phase of the electrical connection apparatus, this drive device moves under the action of the opening mechanism of the main phase switch (not shown in the figures) which acts on the pallet 125.

Le système d'actionnement comporte également un écrou de réglage 110 qui est lié à l'électrode mobile 2 et qui est susceptible de rotation pour ajuster sa position par rapport à l'électrode mobile 2. Durant le mouvement d'ouverture, l'anneau 120 du dispositif d'entraînement vient buter contre un rebord 111 de l'écrou de réglage 110 de façon à pouvoir entraîner l'électrode mobile 2 vers la position ouverte de l'ampoule à vide 1.The actuating system also comprises an adjusting nut 110 which is connected to the movable electrode 2 and is rotatable to adjust its position relative to the moving electrode 2. During the opening movement, the ring 120 of the drive device abuts against a flange 111 of the adjusting nut 110 so as to drive the movable electrode 2 to the open position of the vacuum bottle 1.

Cet écrou de réglage 110 sert donc à transmettre le mouvement du mécanisme d'ouverture de l'appareil de connexion vers l'électrode mobile 2 de l'ampoule à vide 1 et à régler l'instant précis où les électrodes fixe 3 et mobile 2 de l'ampoule à vide vont se séparer en jouant sur l'ajustement entre l'écrou de réglage 110 et l'électrode mobile 2. En effet, en tournant légèrement l'écrou de réglage 110 dans un sens ou dans un autre, on fait varier la distance entre le rebord 111 de l'écrou de réglage 110 et l'anneau 120, et donc on fait varier l'instant où l'électrode mobile 2 va commencer son mouvement d'ouverture.This adjustment nut 110 thus serves to transmit the movement of the opening mechanism of the connection apparatus towards the moving electrode 2 of the vacuum ampoule 1 and to regulate the precise instant when the fixed and movable electrodes 2 of the vacuum bulb will separate by playing on the adjustment between the adjusting nut 110 and the movable electrode 2. Indeed, by slightly turning the adjusting nut 110 in one direction or another, we varies the distance between the flange 111 of the adjusting nut 110 and the ring 120, and thus the time is varied when the moving electrode 2 will begin its opening movement.

Dans le cadre du deuxième mode de réalisation des figures 3 et 4, la liaison entre l'écrou de réglage 110 et l'électrode mobile 2 est faite de la façon suivante : le système d'actionnement comporte une bague filetée 115 dotée d'un filetage extérieur coopérant avec un filetage intérieur de l'écrou de réglage 110 pour ajuster le réglage de l'écrou de réglage 110 par rapport à l'électrode mobile 2, et comporte aussi un goujon 116, un dispositif anti-torsion 118, une rondelle 119 et une vis de fixation 117.In the context of the second embodiment of Figures 3 and 4 , the connection between the adjusting nut 110 and the moving electrode 2 is made as follows: the actuating system comprises a threaded ring 115 having an external thread cooperating with an internal thread of the adjusting nut 110 to adjust the adjustment of the adjusting nut 110 relative to the moving electrode 2, and also comprises a pin 116, an anti-torsion device 118, a washer 119 and a fixing screw 117.

Le goujon 116 comporte un filetage intérieur qui d'un côté coopère avec un filetage extérieur sur l'extrémité de l'électrode mobile 2 et qui de l'autre côté coopère avec la vis de fixation 117. Ainsi, quand la vis 117 est introduite dans la bague 115, elle vient se plaquer contre un rebord de la bague 115 et, une fois vissée au goujon 116, permet de maintenir l'ensemble composé de la bague 115, du goujon 116, du dispositif anti-torsion 118, de la rondelle 119 et de l'électrode mobile 2. La rondelle 119 est utilisée pour fixer un câble conducteur (non représenté sur les figures) permettant de raccorder électriquement l'électrode mobile 2 de l'ampoule à vide 1 à l'appareil de connexion électrique.The stud 116 comprises an internal thread which on one side cooperates with an external thread on the end of the movable electrode 2 and which on the other side cooperates with the fixing screw 117. Thus, when the screw 117 is introduced in the ring 115, it is pressed against a flange of the ring 115 and, once screwed to the stud 116, allows to maintain the assembly composed of the ring 115, the pin 116, the anti-torsion device 118, the washer 119 and the moving electrode 2. The washer 119 is used to fix a conductive cable (not shown in the figures) making it possible to electrically connect the mobile electrode 2 of the vacuum interrupter 1 to the electrical connection apparatus .

Pour éviter tout risque de torsion de l'électrode mobile 2 et donc du soufflet d'étanchéité 4 de l'ampoule à vide 1 durant le mouvement d'ouverture et surtout durant le réglage de l'écrou 110, le dispositif anti-torsion 118 est par exemple une pièce fixe qui est coincée dans le support 5 de l'ampoule à vide 1 et qui comprend des cannelures longitudinales internes coopérant avec des cannelures externes correspondantes sur le goujon 116, de façon à ce que, durant les mouvements de l'électrode mobile 2, le goujon 116 puisse coulisser longitudinalement mais sans risque de rotation par rapport au support 5.To avoid any risk of torsion of the moving electrode 2 and therefore of the sealing bellows 4 of the vacuum bottle 1 during the opening movement and especially during the adjustment of the nut 110, the anti-torsion device 118 is for example a fixed part which is wedged in the support 5 of the vacuum bottle 1 and which comprises internal longitudinal grooves cooperating with corresponding external splines on the stud 116, so that during the movements of the mobile electrode 2, the stud 116 can slide longitudinally but without risk of rotation relative to the support 5.

Enfin, dans le deuxième mode de réalisation, le système d'actionnement comporte en outre un dispositif de blocage qui permet de figer la position de l'écrou de réglage 110 par rapport à l'électrode mobile 2, une fois le réglage effectué. Le dispositif de blocage comporte une bague de blocage 112 qui est amovible. Cette bague de blocage 112 est introduite dans deux avancées latérales 122 s'étendant de part et d'autre de l'anneau 20. Ces avancées comportent par exemple des moyens de clipsage qui permettent d'encliqueter facilement la bague de blocage 112 pour la maintenir en position de blocage une fois le réglage effectué, et qui permettent également de l'enlever très facilement lorsqu'un opérateur veut ajuster la position de l'écrou de réglage 110.Finally, in the second embodiment, the actuating system further comprises a locking device which fixes the position of the adjusting nut 110 relative to the movable electrode 2, once the adjustment is made. The locking device comprises a locking ring 112 which is removable. This locking ring 112 is introduced into two lateral projections 122 extending on either side of the ring 20. These advances comprise, for example, clipping means which make it possible to easily snap the locking ring 112 to maintain it. in the locked position once the adjustment is made, and which also make it possible to remove it very easily when an operator wants to adjust the position of the adjusting nut 110.

Une fois la bague de blocage 112 encliquetée, le blocage de l'écrou de réglage 110 est assuré par des encoches dans la bague de blocage 112 qui coopèrent avec des dents 113 de l'écrou de réglage 110 positionnées autour de sa périphérie extérieure pour empêcher la rotation de l'écrou 110. Le nombre de dents/encoches déterminent la finesse de l'angle de réglage possible de l'écrou de réglage 110 par rapport à l'électrode mobile 2.Once the locking ring 112 snaps into place, locking of the adjusting nut 110 is ensured by notches in the locking ring 112 which cooperate with teeth 113 of the adjusting nut 110 positioned around its outer periphery to prevent the rotation of the nut 110. The number of teeth / notches determine the fineness of the possible adjustment angle of the adjusting nut 110 relative to the movable electrode 2.

Pour pouvoir tourner plus facilement l'écrou de réglage 110 lors du réglage, celui-ci possède optionnellement à son extrémité une forme qui permet de le manipuler avec une clé ou un outil, telle qu'une forme hexagonale dans l'exemple de la figure 3.To be able to turn the adjusting nut 110 more easily during adjustment, it optionally has at its end a shape that makes it possible to handle it with a key or a tool, such as a hexagonal shape in the example of the figure 3 .
