Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention concerne la coupure de courant électrique dans une installation de type moyenne ou bien haute tension.The invention relates to the power failure in an installation of medium or high voltage type.

ÉTAT DE LA TECHNIQUE ANTÉRIEURESTATE OF THE PRIOR ART

Une installation électrique de type haute tension ou moyenne tension comporte typiquement deux types d'appareillages qui sont d'une part les disjoncteurs et d'autre part les sectionneurs.An electrical installation of the high voltage or medium voltage type typically comprises two types of equipment which are on the one hand the circuit breakers and on the other hand the disconnectors.

Un sectionneur comporte un seul jeu de contacts, comprenant un contact de sectionnement fixe et un contact de sectionnement mobile, par lesquels passe le courant lorsque le sectionneur est fermé.A disconnector comprises a single set of contacts, comprising a fixed disconnection contact and a movable disconnection contact, through which the current flows when the disconnector is closed.

Lorsque le sectionneur est ouvert, les contacts de sectionnement sont séparés d'une distance grâce à laquelle le sectionneur présente une certaine rigidité, c'est-à-dire une tenue diélectrique déterminée.When the disconnector is open, the disconnecting contacts are separated by a distance through which the disconnector has a certain rigidity, that is to say a determined dielectric strength.

Un disjoncteur comporte un jeu de contacts permanents montés en parallèle avec un jeu de contacts d'arc. Ces contacts d'arc sont dans une enceinte contenant un gaz diélectrique tel que du SF6 favorisant l'extinction d'un arc électrique se formant entre ces contacts d'arc à l'ouverture du disjoncteur.A circuit breaker has a set of permanent contacts connected in parallel with a set of arcing contacts. These arcing contacts are in an enclosure containing a dielectric gas such as SF6 promoting the extinction of an electric arc formed between these arcing contacts at the opening of the circuit breaker.

Comme les contacts d'arc ne peuvent pas être traversés par un courant nominal pendant un temps trop long, ils sont utilisés seulement en phase de manoeuvre du disjoncteur. En fonctionnement normal, lorsque le disjoncteur est fermé, les contacts permanents sont ainsi fermés, de sorte que le courant nominal passe principalement par ces contacts permanents. Lors de la manoeuvre d'ouverture, les contacts permanents sont ouverts avant l'ouverture des contacts d'arc.As the arcing contacts can not be traversed by a nominal current for a time too long, they are used only during the operation of the circuit breaker. In normal operation, when the circuit-breaker is closed, the permanent contacts are thus closed, so that the nominal current mainly passes through these permanent contacts. During the opening operation, the permanent contacts are open before opening the arcing contacts.

Un disjoncteur et un sectionneur sont généralement utilisés en série pour combiner les caractéristiques et avantages de chaque appareil : le pouvoir de coupure du disjoncteur et la rigidité diélectrique du sectionneur.A circuit breaker and a disconnector are generally used in series to combine the characteristics and advantages of each device: the breaking capacity of the circuit breaker and the dielectric strength of the disconnector.

Le contact d'arc mobile, qui est repéré par 16, est porté par l'embase 9 en étant déplaçable en translation le long de l'axe AX dans l'ampoule et en étant relié électriquement au support fixe 4. Il comporte une portion tubulaire dont l'extrémité vient entourer le contact d'arc fixe 14 pour établir le contact électrique en position fermée comme sur la figure 1, et une buse entourant cette portion tubulaire.The movable arcing contact, which is indicated by 16, is carried by the base 9 by being translatable in translation along the axis AX in the bulb and being electrically connected to the fixed support 4. It comprises a portion tubular whose end comes surround the fixed arcing contact 14 to establish the electrical contact in the closed position as on the figure 1 , and a nozzle surrounding this tubular portion.

En position fermée comme sur la figure 1, le contact d'arc mobile 16 est ainsi déployé dans l'ampoule, pour entourer le contact d'arc fixe 14 en l'enserrant afin d'être en contact électrique avec celui-ci. En position ouverte comme sur la figure 2, ce contact d'arc mobile 16 est au contraire rétracté pour être à distance du contact d'arc fixe 14.In closed position as on the figure 1 , the movable arcing contact 16 is thus deployed in the bulb, to surround the fixed arcing contact 14 by enclosing it in order to be in electrical contact therewith. In open position as on the figure 2 this moving arcing contact 16 is instead retracted to be away from the fixed arcing contact 14.

Lors de l'ouverture du disjoncteur, le contact d'arc mobile 16 est déplacé en translation pour passer de sa position fermée où il est déployé, à sa position ouverte où il est rétracté. Lorsque les contacts d'arc 14 et 16 se séparent durant ce mouvement, un arc électrique s'établit entre eux, et grâce notamment à la présence du gaz isolant SF6, cet arc disparaît avant la fin du mouvement d'ouverture.When opening the circuit breaker, the movable arcing contact 16 is moved in translation to move from its closed position where it is deployed, to its open position where it is retracted. When the arcing contacts 14 and 16 separate during this movement, an electric arc is established between them, and thanks in particular to the presence of insulating gas SF6, this arc disappears before the end of the opening movement.

Lorsque le disjoncteur est refermé, ses contacts d'arc sont alors rapprochés jusqu'à établir le contact électrique lorsque le contact d'arc mobile 16 a atteint sa position de fermeture.When the circuit breaker is closed, its arcing contacts are then brought closer to establishing the electrical contact when the movable arcing contact 16 has reached its closed position.

En service, la totalité du courant nominal ne passe pas par les contacts d'arc, car à terme cela les détériorerait. Le disjoncteur comporte ainsi un contact mobile dit permanent, et par lequel passe la plus grande partie du courant de ligne lorsque le disjoncteur est fermé et n'est pas manoeuvré.In operation, the entire nominal current does not pass through the arcing contacts, because eventually it would deteriorate. The circuit breaker thus has a so-called permanent moving contact, through which the greater part of the line current passes when the circuit-breaker is closed and is not maneuvered.

Le contact permanent mobile, qui est repéré par 17, a ici une forme de tube qui coulisse à l'intérieur de la portion tubulaire 7 du support fixe 4 pour être mobile en translation entre une position fermée et une position ouverte.The moving permanent contact, which is marked by 17, here has a tube shape which slides at the inside of the tubular portion 7 of the fixed support 4 to be movable in translation between a closed position and an open position.

Dans la position fermée correspondant à la figure 1, le contact permanent mobile 17 est déployé pour être en contact électrique avec un autre contacteur repéré par 18. Dans la position ouverte correspondant à la figure 2, le contact permanent mobile 17 est rétracté dans la portion tubulaire 7 pour être espacé de l'autre contact 18.In the closed position corresponding to the figure 1 the movable permanent contact 17 is deployed to be in electrical contact with another contact identified by 18. In the open position corresponding to the figure 2 the movable permanent contact 17 is retracted into the tubular portion 7 to be spaced from the other contact 18.

Le contact permanent mobile 17 est électriquement relié à la portion tubulaire 7 dans laquelle il coulisse grâce à un contact glissant 19 porté par la face interne de la portion tubulaire 7 dans la région d'extrémité de cette portion tubulaire 7. Le contact permanent mobile 17 est ainsi électriquement relié au support fixe 4 quelle que soit la position qu'il occupe.The movable permanent contact 17 is electrically connected to the tubular portion 7 in which it slides through a sliding contact 19 carried by the inner face of the tubular portion 7 in the end region of this tubular portion 7. The movable permanent contact 17 is thus electrically connected to the fixed support 4 regardless of the position it occupies.

Par ailleurs, le contact permanent mobile 17 et le contact d'arc mobile 16 sont liés l'un à l'autre cinématiquement, par des éléments mécaniques non représentés, pour former ici un équipage mobile unique.Furthermore, the movable permanent contact 17 and the movable arcing contact 16 are kinematically connected to one another by mechanical elements, not shown, to form here a single moving element.

Lorsque cet équipage est déplacé de sa position de fermeture à sa position d'ouverture, pour ouvrir le disjoncteur, le contact permanent mobile se déconnecte du contact 18 avant que le contact d'arc mobile 16 ne se déconnecte du contact d'arc fixe 14. L'arc ne peut ainsi pas se former au niveau du contact permanent, mais uniquement au niveau des contacts d'arc.When this crew is moved from its closed position to its open position, to open the circuit breaker, the movable permanent contact disconnects from the contact 18 before the movable arcing contact 16 disconnects from the fixed arcing contact 14 The arc can not be formed at the level of the permanent contact, but only at the level of the arcing contacts.

Dans l'exemple des figures, cet ordre de déconnexion est assuré par un choix approprié des longueurs et positionnements du contact permanent mobile 17 par rapport au contact 18, et du contact d'arc mobile 16 par rapport au contact d'arc fixe 14. Plus concrètement, lorsque l'équipage est en position de fermeture, la longueur d'enfoncement du contact d'arc fixe 14 dans le contact d'arc mobile 16 est plus importante que la longueur d'enfoncement du contact permanent mobile dans le contact 18.In the example of the figures, this disconnection order is ensured by an appropriate choice of the lengths and positions of the moving permanent contact 17 with respect to the contact 18, and the movable arcing contact 16 with respect to the fixed arcing contact 14. More specifically, when the crew is in the closed position, the driving length of the fixed arcing contact 14 in the movable arcing contact 16 is greater than the driving length of the moving permanent contact in the contact 18. .

En ce qui concerne l'autre contact, repéré par 18, il constitue en fait le contact mobile de sectionneur du dispositif, et il est monté coulissant dans le second support fixe 6 du dispositif pour être lui aussi déplaçable en translation le long de l'axe AX.Regarding the other contact, identified by 18, it is in fact the movable contact of the device disconnector, and it is slidably mounted in the second fixed support 6 of the device to be also movable in translation along the AX axis.

Ce second support fixe 6 comporte ainsi, tout comme le premier, une portion tubulaire 21 dont une extrémité est fermée par un fond plat 22. Le contact mobile de sectionneur 18 comporte un corps tubulaire 23 qui est monté coulissant à l'intérieur de la portion tubulaire 21 du support fixe 6. Un contact glissant 24 monté à la face interne de la portion tubulaire 21, dans la région de son extrémité, assure un contact électrique continuel entre le support fixe 6 et le contact de sectionnement mobile18.This second fixed support 6 thus comprises, like the first, a tubular portion 21, one end of which is closed by a flat bottom 22. The movable contact 18 of the disconnector comprises a tubular body 23 which is slidably mounted inside the portion tubular 21 of the fixed support 6. A sliding contact 24 mounted to the inner face of the tubular portion 21, in the region of its end, ensures continuous electrical contact between the fixed support 6 and the movable sectional contact 18.

De la même manière, le corps tubulaire 23 porte dans la région de son extrémité proche du contact permanent mobile 17, c'est-à-dire l'extrémité s'étendant vers le premier support fixe 4, un contact glissant 26 porté par sa face interne.In the same way, the tubular body 23 carries in the region of its end near the moving permanent contact 17, that is to say the end extending towards the first fixed support 4, a sliding contact 26 carried by its internal face.

Ce contact de sectionnement mobile18 est déplaçable en translation entre une position ouverte correspondant à celle de la figure 3 et une position fermée correspondant à celle qu'il occupe dans les figures 1 et 2.This movable cutting contact 18 is movable in translation between an open position corresponding to that of the figure 3 and a closed position corresponding to that he occupies in the Figures 1 and 2 .

Lorsqu'il occupe sa position ouverte, le contact de sectionnement mobile18 est rétracté dans la portion tubulaire 21 pour être espacé du contact permanent mobile 17, que celui-ci soit fermé ou bien ouvert. Lorsqu'il occupe sa position fermée, le contact de sectionnement mobile18 est déployé pour venir en contact avec le contact permanent mobile 17 s'il est fermé, c'est-à-dire déployé comme sur la figure 1.When in its open position, the movable sectional contact 18 is retracted into the tubular portion 21 to be spaced apart from the movable permanent contact 17, whether closed or open. When it occupies its closed position, the movable disconnection contact 18 is deployed to come into contact with the movable permanent contact 17 if it is closed, that is to say deployed as on the figure 1 .

Ainsi, et comme visible sur la figure 1, lorsque le contact permanent mobile 17 occupe sa position déployée de fermeture, si le contact de sectionnement mobile18 occupe aussi sa position déployée de fermeture, il entoure le contact permanent mobile 17 pour être en contact électrique avec celui-ci par l'intermédiaire du contact glissant 26.So, and as visible on the figure 1 when the moving permanent contact 17 occupies its extended closing position, if the movable disconnecting contact 18 also occupies its extended closing position, it surrounds the movable permanent contact 17 to be in electrical contact with it via the contact. sliding 26.

Dans cette situation, le dispositif est complètement fermé, et le courant nominal passe successivement, par le support fixe 4, le contact permanent mobile 17, le contact de sectionnement mobile18, et le second support fixe 6.In this situation, the device is completely closed, and the nominal current passes successively, through the fixed support 4, the contact movable standing 17, the movable cutting contact 18, and the second fixed support 6.

Ce contact de sectionnement mobile18 comporte, outre son corps tubulaire 23, une paroi médiane 27 plane qui s'étend selon un plan normal à l'axe AX, qui ferme le corps tubulaire 23, et qui porte un doigt de contact central 28.This mobile sectioning contact 18 comprises, in addition to its tubular body 23, a planar medial wall 27 which extends in a plane normal to the axis AX, which closes the tubular body 23, and which carries a central contact pin 28.

Ce doigt de contact 28 s'étend selon l'axe de révolution AX en direction de l'ampoule de coupure 11, c'est-à-dire en direction opposée au second support fixe 6.This contact finger 28 extends along the axis of revolution AX towards the breaking bulb 11, that is to say in the direction opposite to the second fixed support 6.

Complémentairement à ce doigt de contact 28, le flanc d'ampoule 13 porte à sa face externe un organe de contact tubulaire 29 dans lequel vient s'engager le doigt de contact 28 lorsque le contact de sectionnement mobile18 occupe sa position de fermeture comme sur la figure 1 ou la figure 2. Dans ces conditions, le contact d'arc fixe 14 du disjoncteur est électriquement relié au second support fixe 6, par l'intermédiaire du flanc d'ampoule 13, de l'organe de contact 29, et du contact de sectionnement mobile18.Complementarily to this contact finger 28, the bulb side 13 carries on its outer face a tubular contact member 29 in which the contact finger 28 engages when the movable disconnection contact 18 occupies its closed position as on the figure 1 or the figure 2 . Under these conditions, the fixed arc contact 14 of the circuit breaker is electrically connected to the second fixed support 6, through the bulb side 13, the contact member 29, and the movable sectional contact 18.

Comme on l'aura compris, en fonctionnement normal, le dispositif de coupure selon l'invention est entièrement fermé, comme dans la figure 1. Son ouverture consiste alors en premier lieu à manoeuvrer l'équipage mobile comprenant le contact permanent mobile 17 et le contact d'arc mobile 16, depuis sa position de fermeture vers sa position d'ouverture, à savoir de gauche à droite sur les figures.As will be understood, in normal operation, the cut-off device according to the invention is completely closed, as in the figure 1 . Its opening then consists first of all in maneuvering the mobile equipment comprising the moving permanent contact 17 and the movable arcing contact 16, from its closed position to its open position, namely from left to right in the figures.

Dans une première phase, le contact permanent mobile 17 se déconnecte du contact de sectionnement mobile 18. A ce stade, la totalité du courant passe par les contacts d'arc 14 et 16, et par le doigt central 28 du contact de sectionnement mobile 18 pour atteindre le support fixe 6.In a first phase, the mobile permanent contact 17 disconnects from the contact of At this stage, the entire current passes through the arcing contacts 14 and 16, and through the central finger 28 of the movable disconnecting contact 18 to reach the fixed support 6.

Lorsque ce mouvement continue, le contact d'arc mobile 16 s'écarte du contact d'arc fixe 14, ce qui provoque la formation d'un arc électrique entre ces deux éléments. Cet arc s'éteint ensuite pendant que continue le mouvement d'écartement du contact d'arc mobile 16, et ce mouvement se termine lorsqu'il a atteint sa position d'ouverture maximale, comme dans la figure 2.When this movement continues, the movable arcing contact 16 deviates from the fixed arcing contact 14, which causes the formation of an electric arc between these two elements. This arc then extinguishes while the movement of the movable arcing contact 16 continues, and this movement ends when it reaches its maximum open position, as in FIG. figure 2 .

A ce stade, le courant est coupé du fait que le contact permanent mobile 17 et le contact de sectionnement 18 sont espacés l'un de l'autre et que le contact d'arc mobile 16 et le contact d'arc fixe 14 sont eux aussi espacés l'un de l'autre.At this stage, the current is cut off because the movable permanent contact 17 and the disconnection contact 18 are spaced from each other and the movable arcing contact 16 and the fixed arcing contact 14 are themselves also spaced apart from each other.

Pour terminer l'ouverture électrique du dispositif, il convient encore de manoeuvrer le contact de sectionnement mobile 18 jusqu'à sa position d'ouverture pour l'écarter le plus possible de la partie formant disjoncteur afin d'assurer une rigidité maximale de la coupure, ce qui correspond à la situation de la figure 3.To complete the electrical opening of the device, it is still necessary to operate the movable disconnection contact 18 to its open position to separate it as much as possible from the circuit breaker portion to ensure maximum rigidity of the cutoff , which corresponds to the situation of the figure 3 .

Comme visible dans la figure 3, dans la situation d'ouverture complète du dispositif, les différents composants de la partie disjoncteur du dispositif et les différents composants de la partie sectionneur du dispositif sont tous espacés les uns des autres, d'une distance minimale repérée par D dans la figure 4.As visible in the figure 3 in the situation of complete opening of the device, the various components of the circuit breaker part of the device and the various components of the disconnector part of the device are all spaced from each other, a minimum distance marked by D in the figure 4 .

Il subsiste ainsi un espace entre ces deux parties, d'une longueur D selon la direction AX, et qui laisse ainsi un espace suffisant pour l'insertion d'un écran permettant d'accroître encore la rigidité électrique. Ceci permet ainsi une intervention humaine sur l'une des parties du dispositif, l'autre partie pouvant alors être laissée sous tension.There is thus a space between these two parts, a length D along the direction AX, and thus leaving enough space for the insertion of a screen to further increase the electrical rigidity. This allows human intervention on one part of the device, the other part can then be left under tension.

A ce titre, on a représenté dans la figure 4 l'intégration d'un dispositif de coupure selon l'invention dans une enceinte comportant une coque 31 dont la partie supérieure est fermée par deux demi-toits 32 et 33 qui couvrent respectivement la partie 2 formant disjoncteur et la partie 3 formant sectionneur.As such, it is shown in the figure 4 the integration of a cut-off device according to the invention in an enclosure comprising a shell 31 whose upper part is closed by two half-roofs 32 and 33 which respectively cover the part 2 forming a circuit breaker and the part 3 forming a disconnector.

Ces deux demi-toits peuvent être ouverts indépendamment l'un de l'autre, et ils sont espacés l'un de l'autre le long de l'axe AX par une fente de faible largeur permettant l'insertion d'un écran électrique 34 avant ouverture de l'un ou l'autre des toits. Cette fente permet d'insérer l'écran, mais elle est suffisamment étroite pour interdire à un technicien de passer son bras ou sa jambe.These two half-roofs can be opened independently of one another, and they are spaced from each other along the axis AX by a slot of small width allowing the insertion of an electric screen 34 before opening one or the other of the roofs. This slot is used to insert the screen, but it is narrow enough to prevent a technician to move his arm or leg.

Une intervention sur la partie disjoncteur du dispositif consiste ainsi à mettre la partie disjoncteur hors tension, insérer l'écran électrique 34 entre les deux demi-toits, en laissant la partie sectionneur sous tension. Le demi-toit 32 couvrant la partie disjoncteur peut alors être ouvert pour permettre à un opérateur d'intervenir sur ce disjoncteur sans risque d'électrocution.An intervention on the circuit breaker part of the device thus consists in putting the circuit-breaker part off, inserting the electric screen 34 between the two half-roofs, leaving the disconnecting part energized. The half roof 32 covering the circuit breaker portion can then be opened to allow an operator to intervene on this circuit breaker without risk of electrocution.

Concrètement, l'écran qui est inséré le long de la partie disjoncteur assure le maintien d'une distance suffisante, à savoir la distance D, entre tous les composants de la partie disjoncteur et tous les composants de la partie sectionneur durant l'intervention de l'opérateur.Specifically, the screen that is inserted along the circuit breaker portion ensures the maintenance of a sufficient distance, ie the distance D, between all the components of the circuit-breaker part and all the components of the disconnecting part during the intervention of the operator.

L'invention apporte ainsi les avantages suivants : en cas d'avarie sur la commande de la partie disjoncteur, la partie formant sectionneur reste opérationnelle et peut être manoeuvrée indépendamment de l'autre partie.The invention thus provides the following advantages: in the event of damage to the control of the circuit breaker part, the disconnector part remains operational and can be operated independently of the other part.

Le dispositif selon l'invention, tout en réunissant un disjoncteur et un sectionneur permet ainsi leurs fonctionnements indépendants. Il est ainsi possible de réaliser sans risque des essais de manoeuvre de la partie disjoncteur, en laissant simplement la partie sectionneur ouverte, par exemple avant mise en service du système.The device according to the invention, while assembling a circuit breaker and a disconnector thus allows their independent operation. It is thus possible to perform without any risk of maneuvering tests of the circuit breaker part, simply leaving the disconnecting part open, for example before commissioning the system.

Grâce à l'espace s'établissant entre la partie disjoncteur et la partie sectionneur lorsque le dispositif est ouvert, il est possible d'insérer un écran pour intervenir sur l'une des parties du dispositif sans devoir mettre l'autre hors tension.Thanks to the space between the circuit breaker and the disconnecting part when the device is open, it is possible to insert a screen to intervene on one part of the device without having to turn off the other.
