Abstract
Description
La présente invention concerne un disjoncteur hybride à haute tension.The present invention relates to a hybrid high-voltage circuit breaker.
Un tel disjoncteur hybride comporte pour chaque pôle une chambre de coupure à gaz diélectrique, par exemple du SF6 sous pression, dont le contact fixe est relié à une première borne du réseau et connecté en série avec un interrupteur supportant le dU/dt de la tension transitoire de rétablissement et dont le contact fixe est relié à une seconde borne du réseau. Cet interrupteur est souvent une ampoule à vide.Such a hybrid circuit breaker comprises for each pole a dielectric gas breaking chamber, for example SF6 under pressure, the fixed contact is connected to a first terminal of the network and connected in series with a switch supporting the dU / dt voltage recovery transient and whose fixed contact is connected to a second terminal of the network. This switch is often a vacuum bulb.
Un tel disjoncteur hybride sous enveloppe métallique dit couramment blindé est décrit dans le
Ce type de disjoncteur hybride pose les problèmes techniques suivants.This type of hybrid circuit breaker poses the following technical problems.
Tout d'abord, compte tenu de l'alignement des éléments de coupure il est particulièrement encombrant.First of all, given the alignment of the cut-off elements, it is particularly bulky.
Par ailleurs, ses moyens d'actionnement ne permettent aucun réglage aisé de ce décalage. Or, selon la puissance du disjoncteur hybride ou selon le gaz diélectrique utilisé, il peut s'avérer utile d'obtenir un décalage temporel plus ou moins grand entre ouverture de la chambre de coupure et l'ampoule.Furthermore, its actuating means do not allow any easy adjustment of this shift. However, depending on the power of the hybrid circuit breaker or the dielectric gas used, it may be useful to obtain a more or less time delay between opening the arc chute and the bulb.
Pour résoudre ces problèmes, il peut être envisagé de disposer la chambre de coupure à gaz et l'ampoule à vide selon deux axes inclinés, le contact mobile de la chambre de coupure étant prolongé par un agencement longitudinal d'entraînement sur lequel est disposé en contact permanent un élément relié au contact mobile de l'ampoule à vide, la commande unique sollicitant le contact mobile de la chambre de coupure en translation selon le premier axe et la longueur et la forme de l'agencement d'entraînement assurant une synchronisation entre les déplacements des contacts mobiles d'une position fermée à une position ouverte des contacts mobiles et inversement.To solve these problems, it can be envisaged to arrange the gas-cutting chamber and the vacuum interrupter along two inclined axes, the movable contact of the interrupting chamber being extended by a longitudinal drive arrangement on which is arranged in permanent contact an element connected to the movable contact of the vacuum interrupter, the single command requesting the movable contact of the translation cleavage chamber along the first axis and the length and shape of the drive arrangement ensuring a synchronization between moving the movable contacts from a closed position to an open position of the moving contacts and vice versa.
Un tel agencement pour un disjoncteur hybride est décrit dans le document de brevet
Cependant, ces agencements posent les problèmes techniques suivants.However, these arrangements pose the following technical problems.
Une fois les contacts mobiles de la chambre de coupure et de l'ampoule à vide en position ouverte, chambre de coupure et ampoule à vide restent en position ouverte. Or dans cette position, l'ensemble des contacts mobiles et les pièces chargées qui leur sont solidaires forment un ensemble à potentiel dit flottant se comportant comme un condensateur et susceptible d'entraîner des décharges partielles susceptibles de dégrader le disjoncteur, par exemple dans les pièces isolantes sous tension, en particulier lorsque la tension aux bornes du disjoncteur est importante. Ceci peut entraîner des réamorçages, compte tenu essentiellement de la faible distance entre les contacts de l'ampoule à vide.Once the movable contacts of the interrupting chamber and the vacuum interrupter are in the open position, the interrupting chamber and the vacuum interrupter remain in the open position. Now in this position, the set of moving contacts and the charged parts which their are integral forming a so-called floating potential behaving as a capacitor and likely to cause partial discharges may degrade the circuit breaker, for example in insulating parts under tension, especially when the voltage across the circuit breaker is important. This can lead to reboots, mainly due to the small distance between the contacts of the vacuum interrupter.
Ce problème peut généralement être résolu par l'installation de sectionneurs montés en série avec le disjoncteur.This problem can usually be solved by installing disconnectors connected in series with the circuit breaker.
Cependant, au cas où l'on supprime cette installation supplémentaire, les performances du disjoncteur et sa durée de vie s'en trouvent affectées.However, in the event that this additional installation is omitted, the performance of the circuit breaker and its lifetime are affected.
Pour résoudre ce problème, l'invention propose un disjoncteur hybride comprenant pour chaque pôle une chambre de coupure à gaz diélectrique comportant un premier contact et un second contact mobile disposés longitudinalement à un premier axe et dont le premier contact est relié à une première borne du réseau, cette chambre de coupure étant connectée en série avec une ampoule à vide comportant un contact fixe et un contact mobile disposés longitudinalement à un second axe et dont le contact fixe est relié à une seconde borne du réseau, des moyens d'actionnement assurant par une commande unique le déplacement entre une position d'ouverture et une position de fermeture desdits contacts mobiles, caractérisé en ce que lesdits moyens d'actionnement comprennent un agencement de refermeture du contact mobile de l'ampoule à vide, assurant cette refermeture par ladite commande unique avant la position d'ouverture du contact mobile de ladite chambre de coupure.To solve this problem, the invention proposes a hybrid circuit breaker comprising for each pole a dielectric gas breaking chamber comprising a first contact and a second movable contact disposed longitudinally at a first axis and whose first contact is connected to a first terminal of the network, this breaking chamber being connected in series with a vacuum bulb having a fixed contact and a movable contact disposed longitudinally to a second axis and whose fixed contact is connected to a second terminal of the network, actuating means ensuring by a single control the movement between an open position and a closed position of said movable contacts, characterized in that said actuating means comprise a reclosing arrangement of the movable contact of the vacuum interrupter, ensuring this reclosing by said single command before the opening position of the movable contact of said breaking chamber.
Une caractéristique importante de l'invention est que cette refermeture de l'ampoule à vide est réalisée par la même commande unique que l'ouverture et la fermeture des contacts permettant ainsi un agencement de commande particulièrement léger. Il en résulte un nombre de pièces limité et un coût et un temps de montage inférieur.An important feature of the invention is that this reclosing of the vacuum bulb is performed by the same single command as the opening and closing of the contacts thus allowing a particularly light control arrangement. This results in a limited number of parts and a lower cost and lower assembly time.
Selon un mode de réalisation préféré, lesdits moyens d'actionnement comprennent un agencement de déplacement du contact mobile de ladite chambre de coupure sur une distance supérieure à la distance entre les contacts de la chambre de coupure en position d'ouverture.According to a preferred embodiment, said actuating means comprise an arrangement for moving the moving contact of said breaking chamber over a distance greater than the distance between the contacts of the interrupting chamber in the open position.
Grâce à cette caractéristique de l'invention, les contacts de la chambre de coupure sont espacés d'une distance supérieure à celle nécessaire à la fonction disjoncteur et la chambre de coupure peut remplir après cette position d'ouverture une fonction de sectionneur.Thanks to this feature of the invention, the contacts of the interrupting chamber are spaced a distance greater than that required for the circuit breaker function and the interrupting chamber can fill after this open position a disconnector function.
Ceci est particulièrement intéressant pour s'affranchir du montage en série d'un sectionneur séparé comme il est fait généralement, afin d'éviter toute possibilité de réamorçages même en cas de fuite de gaz.This is particularly interesting to overcome the serial assembly of a separate disconnector as is generally done, to avoid any possibility of reboots even in case of gas leakage.
Selon une autre caractéristique de l'invention, le disjoncteur hybride comprend un agencement de mise à la terre de la seconde borne actionné par ladite commande unique.According to another characteristic of the invention, the hybrid circuit breaker comprises an arrangement for grounding the second terminal actuated by said single command.
Cette autre caractéristique de l'invention augmente encore la facilité de commande, automatique et synchronisé, du disjoncteur hybride. De façon connue, l'agencement de mise à la terre est un élément sous enveloppe séparé et pourvu d'une commande spécifique. Le disjoncteur conforme à l'invention est donc optimisé quant aux matériels utilisés et donc au coût.This other feature of the invention further increases the ease of control, automatic and synchronized, of the hybrid circuit breaker. In known manner, the grounding arrangement is a separate envelope element provided with a specific control. The circuit breaker according to the invention is optimized for the materials used and therefore the cost.

Selon une première variante, ledit agencement longitudinal d'entraînement est formé par une glissière comportant deux surfaces de roulement parallèles entre elles, ledit élément relié au contact mobile de l'ampoule à vide étant disposé dans ladite glissière et en permanence en contact avec l'une ou l'autre des deux surfaces de roulement.According to a first variant, said longitudinal drive arrangement is formed by a slide having two running surfaces parallel to each other, said element connected to the movable contact of the vacuum interrupter being disposed in said slideway and permanently in contact with it. one or the other of the two running surfaces.
Selon une seconde variante, ledit agencement longitudinal d'entraînement est formé par une came, ledit élément relié au contact mobile de l'ampoule à vide étant apte à appuyer contre la surface de roulement de ladite came du côté opposé à celui de l'ampoule lors de l'activation de la commande des moyens d'actionnement du disjoncteur hybride.According to a second variant, said longitudinal driving arrangement is formed by a cam, said element connected to the moving contact of the vacuum bottle being able to press against the rolling surface of said cam on the side opposite to that of the bulb when activating the control of the operating means of the hybrid circuit breaker.

Le choix de l'angle d'inclinaison de ce deuxième tronçon assure le réglage de la vitesse de séparation des contacts de l'ampoule à vide.The choice of the angle of inclination of this second section ensures the adjustment of the separation speed of the contacts of the vacuum interrupter.
Ledit cinquième tronçon assure la fonction de refermeture de l'ampoule à vide.Said fifth section provides the reclosing function of the vacuum bulb.
Pour remplir la fonction de sectionneur de la chambre de coupure, ledit cinquième tronçon est de longueur supérieure à la distance entre les contacts de la chambre de coupure en fin de position d'ouverture.To fulfill the function of disconnector of the interrupting chamber, said fifth section is longer than the distance between the contacts of the interrupting chamber at the end of the open position.
Selon une première variante, pour remplir la fonction de mise à la terre automatique, ledit agencement de mise à la terre est entraîné par une bielle dont un élément solidaire est disposé dans ladite glissière ou sur la surface de roulement de ladite came, la translation de cette bielle lors du passage de cet élément solidaire dans le deuxième tronçon assurant le déplacement d'un contact relié électriquement à ladite ampoule à vide dans un organe de contact relié à la terre.According to a first variant, to fulfill the function of automatic grounding, said grounding arrangement is driven by a connecting rod of which a fixed element is disposed in said slideway or on the rolling surface of said cam, the translation of this rod at the passage of this integral element in the second section ensuring the displacement of a contact electrically connected to said vacuum bulb in a contact member connected to the ground.

De façon commune à tous les modes de réalisation décrits, un disjoncteur hybride comprend pour chaque pôle une chambre de coupure à gaz diélectrique 1, par exemple du SF6 sous pression, comportant un contact fixe 1A et un contact mobile 1B disposés longitudinalement à un premier axe AA', horizontal vu selon les figures, et dont le contact fixe 1A est relié à une première borne du réseau 3A. Cette chambre de coupure 1 est connectée en série avec une ampoule à vide 2 comportant un contact fixe 2A et un contact mobile 2B disposés longitudinalement à un second axe BB', vertical vu selon les figures, et dont le contact fixe 2A est relié à une seconde borne du réseau 3B.In a manner common to all the embodiments described, a hybrid circuit breaker comprises, for each pole, a dielectric gas breaking chamber 1, for example SF6 under pressure, comprising a
Des moyens d'actionnement assurent par une commande unique 4 le déplacement entre une position d'ouverture et une position de fermeture des contacts mobiles 1B et 2B.Actuating means provide by a single command 4 the movement between an open position and a closed position of the
Ces moyens d'actionnement comprennent un agencement de refermeture du contact mobile 2B de l'ampoule à vide 2, assurant cette refermeture par la commande unique 4 avant la position d'ouverture du contact mobile de la chambre de coupure 1.These actuating means comprise a reclosing arrangement of the
Ils comprennent également un agencement de déplacement du contact mobile 1B de la chambre de coupure 1 sur une distance supérieure à la distance entre les contacts 1A et 1B de la chambre de coupure en fin de position d'ouverture.They also comprise an arrangement for moving the
Le disjoncteur hybride comprend de plus un agencement de mise à la terre automatique actionné par la commande unique 4.The hybrid circuit breaker further comprises an automatic grounding arrangement actuated by the single control 4.
Pour réaliser ces moyens d'actionnement, les deux axes AA' et BB' sont donc sensiblement perpendiculaires et le contact mobile 1B de la chambre de coupure 1 est prolongé par un agencement longitudinal d'entraînement dit glissière sur lequel est disposé en contact permanent un élément relié au contact mobile 2B de l'ampoule à vide 2 et la commande unique 4 sollicite le contact mobile 1B de la chambre de coupure 1 en translation selon le premier axe AA', la longueur et la forme de cet agencement d'entraînement assurant une synchronisation entre les déplacements des contacts mobiles 1B et 2B.To achieve these actuating means, the two axes AA 'and BB' are therefore substantially perpendicular and the
Une premier mode de réalisation est décrit maintenant en référence aux
La glissière est ici réalisée par une rainure 5 agencée sur une pièce prolongeant le contact mobile 1B et reliant celui-ci à la bielle de commande 4A et l'élément relié au contact mobile 2B de l'ampoule à vide 2 est un tenon ou axe 6 perpendiculaire au second axe BB' qui est en prise dans cette rainure 5.The slideway is here made by a

Pour remplir la fonction d'ouverture de l'ampoule à vide 2 à quelques ms de décalage de celle de la chambre de coupure 1, elle comporte un premier tronçon 5A parallèle au premier axe AA', disposé du côté de la commande 4 et prolongé du côté du contact mobile 1B de la chambre de coupure 1 par un deuxième tronçon 5B incliné dans la direction opposée au contact mobile 2B de l'ampoule à vide 2 lui-même prolongé par un troisième tronçon 5C parallèle au premier axe AA' du côté du contact mobile 2B de la chambre de coupure 2.To fulfill the function of opening the
Il apparaît ici un avantage de l'invention. Généralement ce décalage temporel d'ouverture est de l'ordre de 3 ms. Cependant, selon la puissance du disjoncteur et selon le gaz diélectrique utilisé dans la chambre de coupure, ce décalage peut devoir être de valeur différente. Grâce aux moyens d'actionnement conformes à l'invention, il est aisé de d'effectuer ce réglage et de monter un élément à rainure adapté au besoin.Here appears an advantage of the invention. Generally, this time shift of opening is of the order of 3 ms. However, depending on the power of the circuit breaker and the dielectric gas used in the interrupting chamber, this offset may have to be of different value. Thanks to the actuating means according to the invention, it is easy to perform this adjustment and mount a groove element adapted if necessary.
Pour remplir la fonction de refermeture de l'ampoule à vide 2, la rainure 5 se prolonge d'un quatrième tronçon 5D incliné vers le contact mobile 2B de l'ampoule à vide 2 lui-même prolongé par un cinquième tronçon 5 E parallèle au premier axe AA' du côté du contact mobile 1B de la chambre de coupure 1.To fulfill the function of reclosing the
