Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention concerne le domaine des disjoncteurs de la haute tension et très haute tension électrique (Blindé et Dead tank) comportant, pour chaque phase, au moins deux chambres de coupures mises en série électriquement et une transmission commune.The invention relates to the field of circuit breakers of the high voltage and very high electrical voltage (shielded and dead tank) comprising, for each phase, at least two electrically series cut chambers and a common transmission.

La mise en série des chambres de coupure permet lors de la coupure de courant de défaut (courant de court-circuit par exemple) de répartir la tension entre les chambres pour faciliter l'extinction de l'arc.Switching the interrupting chambers in series makes it possible, when the fault current is cut (short-circuit current for example), to distribute the voltage between the chambers in order to facilitate the extinction of the arc.

ART ANTÉRIEURPRIOR ART

Actuellement, un disjoncteur à haute ou très haute tension peut comprendre plusieurs, notamment trois, chambres de coupure alignées.Currently, a high or very high voltage circuit breaker may include several, including three, cutoff chambers aligned.

Pour transmettre le mouvement d'une première chambre de coupure à une deuxième chambre, des tirants isolants extérieurs aux chambres sont utilisés pour ouvrir l'ensemble des contacts mobiles simultanément. L'utilisation de tels tirants implique la nécessité d'utiliser également des capotages ainsi que de prévoir de longues distances d'isolants, c'est-à-dire des distances non négligeables entre ces tirants sous tension et les cuves métalliques au potentiel de la terre.To transmit the movement of a first interrupting chamber to a second chamber, insulating tie rods external to the chambers are used to open the set of moving contacts simultaneously. The use of such tie rods implies the need to also use cowls as well as to provide long distances of insulators, that is to say significant distances between these tie rods under tension and the metal tanks at the potential of the earth.

On peut citer par exemple le document US 3,895,202 qui divulgue une transmission commune à quatre chambres de coupure alignées et réalisée par deux tirants extérieurs 80,82.For example, the document US 3,895,202 which discloses a transmission common to four aligned cutting chambers and made by two outer tie rods 80,82.

Le document US 4,562,319 qui est un perfectionnement du brevet US 3,895,202 divulgue également une transmission commune à quatre chambres de coupure alignées et décalées en parallèle longitudinalement deux à deux, la transmission étant également par des tirants extérieurs.The document US 4,562,319 which is a patent enhancement US 3,895,202 also discloses a common transmission to four cutting chambers aligned and offset in parallel longitudinally two by two, the transmission being also by external tie rods.

Le document FR2682807 décrit un disjoncteur haute tension comprenant, par phase, une cuve métallique dans laquelle sont logées au moins deux chambres de coupure montées électriquement en série l'une avec l'autre et comprenant chacune une paire de contacts principaux, dans lequel

  • les chambres de coupure sont agencées parallèlement entre elles dans la cuve,
  • les extrémités des chambres par lesquelles la manoeuvre d'au moins une paire de contacts mobiles de chaque chambre est réalisée, sont situées dans un même plan,
  • l'ensemble mécanique de transmission par lequel la transmission de mouvement simultanée et une longueur de course identique entre les contacts mobiles
    d'au moins deux chambres sont réalisées, comprend d'une part, au moins deux bielles de longueur identique accouplées chacune avec la paire de contacts mobiles d'une des chambres et d'autre part, des moyens de manoeuvre accouplés aux bielles et adaptés pour être accouplés à au moins une tige de manoeuvre.
The document FR2682807 discloses a high-voltage circuit breaker comprising, per phase, a metal tank in which are housed at least two breaking chambers electrically connected in series with each other and each comprising a pair of main contacts, in which
  • the breaking chambers are arranged parallel to each other in the tank,
  • the ends of the chambers through which the operation of at least one pair of movable contacts of each chamber is performed, are located in the same plane,
  • the mechanical transmission unit by which the simultaneous motion transmission and an identical stroke length between the moving contacts
    at least two chambers are formed, comprises firstly at least two rods of identical length each coupled with the pair of movable contacts of one of the chambers and secondly, maneuvering means coupled to the rods and adapted to be coupled to at least one operating rod.

Ainsi, les structures divulguées impliquent une longueur de disjoncteur importante. De plus, les pièces mécaniques utilisées pour la transmission ainsi que leur agencement peuvent générer des difficultés. Lors de la manoeuvre les pièces mécaniques se déforment, ce qui crée une désynchronisation entre les chambres, même dans les cas où le réglage du disjoncteur en manoeuvre lente a été correctement réalisé. La transmission par tirants implique également un surplus de masse mobile non négligeable d'où un dimensionnement des pièces avec des charges plus importantes. De plus, il est nécessaire d'assurer un guidage, tout en assurant des anti-rotations et le passage de ces pièces prévues à cet effet à travers les pièces formant le support des chambres de coupure.Thus, the disclosed structures involve a large circuit breaker length. In addition, the mechanical parts used for transmission and their arrangement can cause difficulties. During the operation the mechanical parts are deformed, which creates a desynchronization between the chambers, even in cases where the adjustment of the circuit breaker in slow operation was correctly realized. Transmission by tie rods also implies a significant surplus of mobile mass hence dimensioning parts with larger loads. In addition, it is necessary to provide guiding, while ensuring anti-rotation and the passage of these parts provided for this purpose through the parts forming the support of the cutting chambers.

Pour pallier à ces inconvénients, le demandeur a proposé dans la demande de brevet FR0758322 , une amélioration qui permet notamment de réduire la longueur totale d'un disjoncteur avec des chambres de coupure alignées et de simplifier les moyens mécaniques de transmission ainsi que leur agencement.To overcome these disadvantages, the applicant proposed in the patent application FR0758322 , an improvement which makes it possible in particular to reduce the total length of a circuit-breaker with aligned cutting chambers and to simplify the mechanical transmission means and their arrangement.

Le but de l'invention est alors de proposer une autre solution qui permette de réduire la longueur totale du disjoncteur et de s'affranchir des difficultés de transmission du mouvement à toutes les chambres de coupures.The object of the invention is then to propose another solution which makes it possible to reduce the total length of the circuit-breaker and to overcome the difficulties of transmitting the movement to all the breaking chambers.

EXPOSÉ DE L'INVENTIONSTATEMENT OF THE INVENTION

A cet effet, l'invention concerne un disjoncteur haute ou très haute tension comprenant, par phase, une cuve métallique dans laquelle sont logées au moins deux chambres de coupure montées électriquement en série l'une avec l'autre et comprenant chacune une paire de contacts principaux et une paire de contacts d'arc solidaires chacun d'un des contacts principaux, dans lequel :

  • les chambres de coupure sont agencées parallèlement entre elles dans la cuve,
  • les extrémités des chambres par lesquelles la manoeuvre d'au moins une paire de contacts mobiles de chaque chambre est réalisée, sont situées dans un même plan,
  • l'ensemble mécanique de transmission par lequel la transmission de mouvement simultanée et une longueur de course identique entre les contacts mobiles d'au moins deux chambres sont réalisées, comprend d'une part au moins deux bielles de longueur identique accouplées chacune avec la paire de contacts mobiles d'une des chambres et d'autre part des moyens de manoeuvre accouplés aux bielles et adaptés pour être accouplés à au moins une tige de manoeuvre extérieure à la cuve ou traversant sa paroi.
To this end, the invention relates to a high or very high voltage circuit breaker comprising, per phase, a metal vessel in which are housed at least two breaking chambers electrically connected in series with each other and each comprising a pair of main contacts and a pair of integral arcing contacts each of one of the main contacts, wherein:
  • the breaking chambers are arranged parallel to each other in the tank,
  • the ends of the chambers through which the operation of at least one pair of movable contacts of each chamber is performed, are located in the same plane,
  • the mechanical transmission unit by which the simultaneous movement transmission and an identical stroke length between the moving contacts of at least two chambers are made, comprises firstly at least two rods of identical length each coupled with the pair of mobile contacts of one of the rooms and on the other hand means of Maneuvering coupled to the connecting rods and adapted to be coupled to at least one actuating rod external to the tank or through its wall.

Selon l'invention, on minimise la distance entre les entrées de mouvement de chaque chambre et la commande (tige(s) de manoeuvre). Cela permet de réduire la longueur totale mais également hors-tout du disjoncteur (c'est-à-dire la longueur d'encombrement longitudinal du disjoncteur comprenant celle de la cuve), bien que celui-ci intègre au moins deux chambres de coupure. Dans la configuration où les moyens de manoeuvre sont agencés au moins en partie à l'extérieur de la cuve, la longueur hors-tout à prendre en considération est la longueur d'encombrement comprenant celle des moyens de manoeuvre dans la position extrême d'ouverture lors d'une coupure. En outre, le transport et le montage du disjoncteur selon l'invention sont facilités.According to the invention, the distance between the movement inputs of each chamber and the control (operating rod (s)) is minimized. This reduces the overall length, but also overall circuit breaker (that is to say the length of longitudinal circuit of the circuit breaker including that of the tank), although it incorporates at least two breaking chambers. In the configuration where the operating means are arranged at least partly outside the tank, the overall length to be taken into consideration is the overall length including that of the operating means in the extreme open position during a break. In addition, the transport and assembly of the circuit breaker according to the invention are facilitated.

Enfin, grâce à l'invention, on améliore la répartition de la tension sur au moins deux chambres de coupure de façon égale car, les capacités parasites entre les chambres de coupure et la cuve sont réduites.Finally, thanks to the invention, the distribution of the voltage on at least two breaking chambers is improved in an equal manner because the parasitic capacitances between the breaking chambers and the tank are reduced.

La manoeuvre réalisée par la tige selon l'invention est exclusivement une translation qui sépare chaque contact mobile du contact fixe d'une paire donnée dans une même chambre en translation selon l'axe de ladite chambre.The maneuver carried out by the rod according to the invention is exclusively a translation which separates each movable contact from the fixed contact of a given pair in the same room in translation along the axis of said chamber.

Les chambres de coupure sont des modules dans lesquels les contacts principaux et d'arc sont coaxiaux.Break chambers are modules in which the main and arc contacts are coaxial.

Selon un mode de réalisation avantageux, le disjoncteur selon l'invention comprend trois ou quatre chambres de coupure.According to an advantageous embodiment, the circuit breaker according to the invention comprises three or four breaking chambers.

Selon un mode de réalisation, chaque paire de contact comprend deux contacts mobiles, des moyens de transmission supplémentaires pour séparer mutuellement les contacts principaux et d'arc lors d'une coupure étant prévus pour chaque chambre.According to one embodiment, each pair of contacts comprises two movable contacts, additional transmission means for mutually separating the main and arc contacts during a break being provided for each chamber.

Deux alternatives pour réaliser la commande peuvent être prévues. Les moyens de manoeuvre accouplés aux bielles et des tiges de manoeuvre peuvent réaliser au moins deux commandes distinctes.Two alternatives for carrying out the order can be provided. The operating means coupled to the connecting rods and maneuvering rods can achieve at least two separate commands.

Les moyens de manoeuvre accouplés aux bielles peuvent alternativement former un palonnier adapté pour être accouplé à une unique tige de manoeuvre.Maneuvering means coupled to the connecting rods may alternatively form a spreader adapted to be coupled to a single operating rod.

Par « palonnier », il faut comprendre ici et dans le cadre de l'invention, tout dispositif mécanique qui permet l'accouplement aux bielles elles-mêmes accouplées chacune à une paire de contacts mobiles d'une chambre de coupure et, qui permet la transmission concomitante du mouvement aux bielles avec, pour chacune, une répartition équitable de l'effort de traction ou de compression généré par la tige de manoeuvre. Selon le mode de réalisation avantageux avec trois chambres de coupure, le palonnier permet l'accouplement aux trois bielles de longueur identique avec transmission concomitante du mouvement aux trois bielles, avec pour chacune, une répartition équitable en trois de l'effort de traction ou de compression généré par la tige de manoeuvre.By "spreader" is understood here and in the context of the invention, any mechanical device that allows coupling to the rods themselves each coupled to a pair of movable contacts of a cutoff chamber and, which allows the concomitant transmission of the movement to the rods with, for each, a fair distribution of the tensile force or compression generated by the operating rod. According to the advantageous embodiment with three breaking chambers, the spreader allows the coupling to the three connecting rods of identical length with concomitant transmission of the movement to the three connecting rods, with for each, a fair distribution in three of the traction force or compression generated by the operating rod.

Selon une variante, le palonnier est agencé à l'extérieur de la cuve.According to one variant, the spreader is arranged outside the tank.

Selon une variante alternative, le palonnier est agencé à l'intérieur de la cuve.According to an alternative variant, the lifter is arranged inside the vessel.

Le palonnier peut être en matériau isolant électriquement et accouplé à la tige de manoeuvre en matériau conducteur électriquement.The lifter may be electrically insulating material and coupled to the actuating rod electrically conductive material.

Alternativement, le palonnier peut être en matériau conducteur électriquement et accouplé aux bielles en matériau isolant électriquement.Alternatively, the lifter may be electrically conductive material and coupled to the connecting rods of electrically insulating material.

Avantageusement, le maintien mécanique des chambres de coupure dans la cuve est réalisé sur le seul côté du disjoncteur en regard de la(des) tige(s) de manoeuvre par des éléments isolants formant manchons fixés à la paroi de la cuve.Advantageously, the mechanical maintenance of the cut-off chambers in the tank is performed on the single side of the circuit breaker facing the rod (s) maneuvering by insulating elements forming sleeves attached to the wall of the tank.

Avantageusement encore, le disjoncteur comprend des éléments de connexion électriques entre les deux chambres de coupure qui permettent la sortie du courant électrique, au moins une partie desdits éléments étant agencée parallèlement au plan dans lequel sont situées les extrémités des chambres de coupure par lesquelles la manoeuvre de la paire de contacts mobiles de chaque chambre est réalisée.Advantageously, the circuit breaker comprises electrical connection elements between the two breaking chambers which allow the output of the electric current, at least a portion of said elements being arranged parallel to the plane in which are located the ends of the breaking chambers by which the maneuver the pair of movable contacts of each chamber is realized.

Selon une variante où seulement deux chambres de coupure sont agencées à l'intérieur de la cuve métallique, les éléments de connexion électriques comprennent une barre métallique également agencée dans la cuve parallèlement aux chambres, la barre étant connectée à la partie des éléments de connexion électrique agencée parallèlement au plan des extrémités des chambres par lesquelles la manoeuvre de la paire de contacts mobiles de chaque chambre est réalisée.According to a variant where only two breaking chambers are arranged inside the metal tank, the electrical connection elements comprise a metal bar also arranged in the tank parallel to the chambers, the bar being connected to the part of the electrical connection elements. arranged parallel to the plane of the ends chambers through which the operation of the pair of movable contacts of each chamber is performed.

Les chambres de coupure peuvent être réalisées avec des ampoules à vide.Cutoff chambers can be made with vacuum bulbs.

Le disjoncteur selon l'invention peut être agencé non horizontalement en tant que partie d'un Dead tank.The circuit breaker according to the invention can be arranged not horizontally as part of a Dead tank.

L'invention concerne également l'utilisation d'un disjoncteur décrit précédemment en tant que partie d'un poste sous enveloppe métallique (PSEM).The invention also relates to the use of a circuit breaker previously described as part of a metal envelope station (PSEM).

L'invention concerne enfin un procédé de montage d'un disjoncteur décrit précédemment, dans lequel on réalise le pré-assemblage au moins de deux chambres de coupure et des moyens de manoeuvre à accoupler aux bielles, sur une pièce formant couvercle de la cuve puis on loge au moins les deux chambres de coupure dans la cuve par fermeture du corps de cuve avec l'ensemble pré-assemblé.The invention finally relates to a method of mounting a circuit breaker described above, in which the pre-assembly is carried out at least two breaking chambers and operating means to be coupled to the connecting rods, on a part forming a lid of the tank and then at least the two cut-off chambers are housed in the tank by closing the tank body with the pre-assembled assembly.

Chaque paire de contacts comprend un seul contact principal 2a, 2b ou d'arc 4a ; 4b mobiles. (figures 1A et 2). Par souci de clarté, l'ensemble des contacts de la troisième chambre n'est pas représenté.Each chamber Ca, Cb, Cc respectively comprises a pair of main contacts 2a, 3a, 2b, 3b, a pair of arcing contacts 4a, 5a; 4b, 5b each integral with one of the main contacts in part of complementary male and female forms. Each pair of contacts comprises a single main contact 2a, 2b or arc 4a; 4b mobile. ( Figures 1A and 2 ). For the sake of clarity, all the contacts of the third chamber is not shown.

Dans les modes de réalisation illustrés, les trois chambres Ca, Cb, Cc sont identiques.In the illustrated embodiments, the three chambers Ca, Cb, Cc are identical.

Selon l'invention, les chambres de coupure Ca, Cb, Cc sont tout d'abord agencées parallèlement dans la cuve 1 (figures 1A et 2). Dans les modes de réalisation illustrés, elles sont agencées entre elles selon un angle θ de 120° (figure lA).According to the invention, the breaking chambers Ca, Cb, Cc are first arranged in parallel in the tank 1 ( Figures 1A and 2 ). In the illustrated embodiments, they are arranged together at an angle θ of 120 ° (Figure 1A).

Selon l'invention également, les extrémités 6a, 6b, 6c des chambres Ca, Cb et Cc par laquelle la manoeuvre de la paire de contacts mobiles 2a, 4a ; 2b, 4b de chaque chambre est réalisée, sont situées dans un même plan X.According to the invention also, the ends 6a, 6b, 6c of the chambers Ca, Cb and Cc by which the operation of the pair of movable contacts 2a, 4a; 2b, 4b of each chamber is realized, are located in the same plane X.

Enfin, selon l'invention, l'ensemble mécanique de transmission par lequel la transmission de mouvement simultanée entre les contacts mobiles 2a, 4a de la première Ca, 2b, 4b de la deuxième Cb ceux de la troisième Cc chambres est réalisée, comprend trois bielles 7a, 7b, 7c de longueur identique accouplés chacun avec la paire de contacts mobiles 2a, 4a ; 2b, 4b des chambres. L'ensemble comprend également des moyens formant palonnier 8, accouplé aux trois bielles 7a, 7b, 7c et adapté pour être accouplé à une unique tige de manoeuvre extérieure 9 à la cuve 1.Finally, according to the invention, the mechanical transmission unit by which the simultaneous motion transmission between the movable contacts 2a, 4a of the first Ca, 2b, 4b of the second Cb those of the third Cc chambers is performed, comprises three connecting rods 7a, 7b, 7c of identical length each coupled with the pair of movable contacts 2a, 4a; 2b, 4b rooms. The assembly also comprises lifter means 8, coupled to the three connecting rods 7a, 7b, 7c and adapted to be coupled to a single external operating rod 9 to the vessel 1.

Dans le mode de réalisation des figures 1 et 1A, le palonnier 8 est en matériau isolant électriquement et est agencé à l'extérieur de la cuve 1. Dans ce même mode, les bielles 7a, 7b, 7c sont également en matériau isolant électriquement, tandis que l'unique tige de manoeuvre 9 est métallique. Dans la configuration où le palonnier 8 est agencé à l'intérieur de la cuve métallique 1, le palonnier 8 peut être en matériau isolant électriquement, ce qui permet de n'avoir qu'une seule des trois bielles 7a, 7b, 7c en matériau isolant.In the embodiment of Figures 1 and 1A , the lifter 8 is made of electrically insulating material and is arranged outside the vessel 1. In this same mode, the rods 7a, 7b, 7c are also electrically insulating material, while the single operating rod 9 is metallic. In the configuration where the lifter 8 is arranged inside the metal vessel 1, the lifter 8 may be of electrically insulating material, which allows to have only one of the three connecting rods 7a, 7b, 7c of material insulating.

Les bielles 7a, 7b et 7c peuvent être en matériau isolant et le palonnier 8 conducteur (métal). Le palonnier 8 peut être à l'intérieur de la cuve 1 et la tige 9 peut aussi traverser la paroi de la cuve (un système d'étanchéité étant prévu à cet effet). Comme représenté à la figure 1A, le palonnier 8 peut être à l'extérieur de la cuve 1 avec trois systèmes d'étanchéité (non représentés) dans la prolongation (en métal) des bielles isolantes 7a, 7b et 7c. Selon une variante, le palonnier 8 peut être en matériau isolant.The rods 7a, 7b and 7c may be of insulating material and the rudder 8 conductor (metal). The lifter 8 can be inside the tank 1 and the rod 9 can also pass through the wall of the tank (a sealing system is provided for this purpose). As represented in Figure 1A , the lifter 8 can be outside the tank 1 with three systems sealing (not shown) in the extension (metal) insulating rods 7a, 7b and 7c. Alternatively, the lifter 8 may be of insulating material.

Dans le mode de réalisation illustré des figures 1 et 1A, les chambres de coupure Ca, Cb, Cc sont maintenues sur un seul côté 10 du disjoncteur D en regard de la tige de manoeuvre 9 par des tubes isolants formant manchons 11 fixés à la cuve 1. Plus précisément, le palonnier 8, les chambres de coupure Ca, Cb, Cc et les manchons 11a, 11b, 11c sont fixés au préalable du montage du disjoncteur D sur une pièce formant couvercle 10. Puis, les chambres Ca, Cb, Cc de ce sous-ensemble sont introduites dans le corps de cuve 12 en les positionnant de manière à les connecter aux jeux de barre usuelles d'entrée du courant 13 et de sortie du courant 14. Le couvercle 10 est alors fixé au corps de cuve 12.In the illustrated embodiment of the Figures 1 and 1A , the breaking chambers Ca, Cb, Cc are maintained on one side only of the circuit-breaker D facing the operating rod 9 by insulating tubes forming sleeves 11 fixed to the tank 1. More precisely, the lifter 8, the chambers Ca, Cb, Cc and the sleeves 11a, 11b, 11c are fixed in advance of mounting the circuit breaker D on a cover part 10. Then, the chambers Ca, Cb, Cc of this subset are introduced into the body of vessel 12 by positioning them so as to connect them to the usual busbars current input 13 and output current 14. The cover 10 is then fixed to the vessel body 12.

Les disjoncteurs représentés comprennent en outre des éléments de connexion électriques 15 entre les trois chambres de coupure Ca, Cb et Cc qui permettent la sortie du courant électrique, lesdits éléments 15 étant agencés parallèlement au plan X dans lequel sont situées les extrémités des chambres de coupure 6a, 6b, 6c.The circuit breakers shown furthermore comprise electrical connection elements 15 between the three breaking chambers Ca, Cb and Cc which allow the output of the electric current, said elements 15 being arranged parallel to the plane X in which the ends of the breaking chambers are located. 6a, 6b, 6c.

Dans les modes de réalisation illustrés, les contacts d'arc mobiles sont sous la forme de tulipe 4a, 4b et les contacts fixes sont sous la forme de tiges 5a, 5b chacune prolongée par un trépied.In the illustrated embodiments, the movable arcing contacts are in the form of tulip 4a, 4b and the fixed contacts are in the form of rods 5a, 5b each extended by a tripod.

L'architecture prévue selon l'invention, permet l'implantation aisée d'inséreurs de résistance 16 en ligne tels qu'illustrés en figure 2 et, avantageusement selon la dimension longitudinale (axe de symétrie) de la cuve. Les modes de réalisation illustrés sont particulièrement avantageux pour des applications de très hautes tensions supérieures à 800 kV.The architecture provided according to the invention allows the easy implantation of resistance inserters 16 in line as illustrated in FIG. figure 2 and, advantageously according to the longitudinal dimension (axis of symmetry) of the vessel. The illustrated embodiments are particularly advantageous for applications with very high voltages higher than 800 kV.

Le mode de réalisation de la figure 2 permet d'avoir un disjoncteur 1 plus compact que celui des figures 1 et 1A, dans la mesure où les barres d'entrée 13 et de sortie 14 du courant sont agencées sous la forme d'un V convergent vers l'intérieur de la cuve 1 (figure 2).The embodiment of the figure 2 allows to have a circuit breaker 1 more compact than that of Figures 1 and 1A , in that the input and output bars 14 of the current are arranged in the form of a convergent V towards the inside of the vessel 1 ( figure 2 ).

Dans un mode de réalisation non illustré selon lequel deux chambres de coupure seulement sont agencées dans la cuve, telles que par exemple deux chambres Ca et Cb, une barre métallique de connexion électrique peut être implantée en lieu et place de la troisième chambre de coupure Cc. Dans une telle configuration, une bielle de type celle référencée 7c est supprimée. Autrement dit, la barre est fixe et n'a pas de liaison mécanique avec les moyens de manoeuvre. L'utilisation d'une barre métallique à des fins de connexion électrique entre les deux chambres de coupure est avantageuse dans les applications où l'on souhaite avoir une distance déterminée entre l'arrivée 13 et la sortie 14 de courant dans le disjoncteur. Une application visée ici est un disjoncteur de type live tank.In a non-illustrated embodiment in which two interrupting chambers only are arranged in the tank, such as for example two chambers Ca and Cb, a metal electrical connection bar may be implanted in place of the third Cc breaking chamber. . In such a configuration, a rod of the type referenced 7c is removed. In other words, the bar is fixed and has no mechanical connection with the operating means. The use of a metal bar for electrical connection between the two breaking chambers is advantageous in applications where it is desired to have a determined distance between the inlet 13 and the current output 14 in the circuit breaker. An application referred to here is a circuit breaker type live tank.

L'invention est simple à réaliser et permet d'utiliser au moins deux, typiquement trois chambres de coupure usuelles dont la forme et les dimensions n'ont pas à être spécifiques à l'invention.The invention is simple to implement and makes it possible to use at least two, typically three usual cutting chambers whose shape and dimensions need not be specific to the invention.

Les autres avantages de la solution selon l'invention sont nombreux :

  • réduction de la longueur de la cuve,
  • élimination de la nécessité de transmettre le mouvement d'une chambre de coupure à une autre,
  • facilité de transport d'un tel disjoncteur selon l'invention,
  • possibilité d'implantation d'inséreurs de résistance dans l'axe de la cuve,
  • réduction des contraintes mécaniques sur les pièces de manoeuvre isolantes,
  • synchronisation de la manoeuvre d'au moins deux, typiquement trois chambres de coupure.
The other advantages of the solution according to the invention are numerous:
  • reduction of the length of the tank,
  • eliminating the need to transmit movement from one break chamber to another,
  • ease of transport of such a circuit breaker according to the invention,
  • possibility of implantation of resistance inserters in the axis of the tank,
