Abstract

In the circuit breaker, the opening and closure of each breaking chamber (1-3) are effected by a shaft (7) rotated by a controller (16) via a rod (15) and crank (8'). The axis (9') on which the rods are jointed to the cranks comes into line with the axis (5) of rotation of the housing (4) contg. the shaft, when the contacts of the breaking chambers are in the open position. Each moving contact is operated by a lever (11) pivoted about a fixed axis (12) and jointed to an actuating rod (10) whose other end (9) is raised and lowered by a parallel crank (8).

Description

La présente invention se rapporte à un disjoncteur auto-sectionneur à sectionnement auto-verrouillé en position fermée des chambres de coupure, en particulier des ampoules à vide.The present invention relates to a self-isolating circuit breaker with self-locked disconnection in the closed position of the interrupting chambers, in particular vacuum interrupters.

Elle concerne plus précisément un disjoncteur auto-sectionneur comportant au moins une chambre de coupure dont l'ouverture et la fermeture sont actionnées par un mécanisme d'actionnement et qui est fixée à un profilé dans lequel est logé un arbre rotatif d'actionnement de la chambre entraîné en rotation par un dispositif de commande, ledit profilé pouvant tourner autour d'un axe fixe, dit premier axe.More specifically, it relates to a self-isolating circuit breaker comprising at least one breaking chamber, the opening and closing of which are actuated by an actuation mechanism and which is fixed to a profile in which is housed a rotary actuation shaft for the chamber driven in rotation by a control device, said profile being able to rotate about a fixed axis, called the first axis.

Un tel dispositif de commande est décrit dans le document de brevet FR-2 683 939 déposé le 20 novembre 1991. selon ce document antérieur, le dispositif de commande est solidaire du profilé. Ce profilé peut tourner pour déconnecter ou embrocher la chambre de coupure de ou sur les jeux de barres, afin de passer en position de sectionnement ou en position de connexion. Lors de cette rotation, la chambre de coupure et également le dispositif de commande sont basculés en un ensemble monobloc.Such a control device is described in patent document FR-2 683 939 filed on November 20, 1991. according to this prior document, the control device is integral with the profile. This profile can rotate to disconnect or plug in the interrupting chamber from or on the busbars, in order to pass into the sectioning position or into the connection position. During this rotation, the breaking chamber and also the control device are tilted into a one-piece assembly.

Cet agencement connu pose le problème technique suivant.This known arrangement poses the following technical problem.

Il est impératif que le basculement en position sectionnée ne puisse se produire que lorsque les contacts des chambres de coupure sont en position ouverte. Un dispositif tel que décrit dans l'art antérieur nécessite donc un dispositif de verrouillage spécifique empêchant la manoeuvre de sectionnement en position fermée des chambres de coupure.It is imperative that the tilting in the sectioned position can only occur when the contacts of the switching chambers are in the open position. A device as described in the prior art therefore requires a specific locking device preventing the sectioning operation in the closed position of the breaking chambers.

Le but de l'invention est de proposer un disjoncteur auto-sectionneur qui permet un auto-verrouillage du basculement vers la position de sectionnement lorsque les contacts des chambres de coupure sont en position fermée.The object of the invention is to propose a self-isolating circuit breaker which allows self-locking of the tilting towards the isolating position when the contacts of the breaking chambers are in the closed position.

Pour ce faire, conformément à l'invention, ledit dispositif de commande est fixe, le dispositif de commande entraîne en rotation l'arbre d'actionnement par l'intermédiaire d'une tringle de commande articulée selon un axe, dit second axe, à une bielle montée sur l'arbre d'actionnement et, en position ouverte des contacts de la chambre de coupure, lesdits premier et second axes sont alignés.To do this, in accordance with the invention, said control device is fixed, the control device rotates the actuating shaft by means of a control rod articulated along an axis, called the second axis, at a connecting rod mounted on the actuating shaft and, in the open position of the contacts of the interrupting chamber, said first and second axes are aligned.

Ainsi est également réalisé un allégement de l'effort nécessaire pour le déplacement de la position sectionnée vers la position embrochée et inversement.This also reduces the effort required to move from the sectioned position to the plugged-in position and vice versa.

De préférence, ledit mécanisme d'actionnement comporte ledit arbre d'actionnement supportant une bielle articulée selon un axe à une extrémité d'une tige de manoeuvre dont l'autre extrémité est articulée à une extrémité d'un levier de renvoi pivotant sur un axe fixe et actionnant le contact mobile de la chambre, ledit axe étant aligné audit second axe.Preferably, said actuation mechanism comprises said actuation shaft supporting a connecting rod articulated along an axis at one end of an operating rod whose other end is articulated at one end of a return lever pivoting on an axis fixed and actuating the movable contact of the chamber, said axis being aligned with said second axis.

Avantageusement, lesdits premier et second axes sont horizontaux.Advantageously, said first and second axes are horizontal.

L'invention est décrite ci-après plus en détail à l'aide de figures ne représentant qu'un mode de réalisation préféré de l'invention.The invention is described below in more detail using figures showing only a preferred embodiment of the invention.

La figure 1 est une vue en perspective d'un disjoncteur auto-sectionneur triphasé conforme à l'invention.Figure 1 is a perspective view of a three-phase self-disconnecting circuit breaker according to the invention.

Les figures 2 et 3 sont des vues schématiques de côté du dispositif de commande de l'invention.Figures 2 and 3 are schematic side views of the control device of the invention.

Un disjoncteur auto-sectionneur triphasé, comme représenté sur la figure 1, comporte trois chambres de coupure 1, 2, 3, en particulier des ampoules à vide.A three-phase self-disconnecting circuit breaker, as shown in FIG. 1, comprises three breaking chambers 1, 2, 3, in particular vacuum interrupters.

Leur ouverture et leur fermeture sont actionnées par un mécanisme d'actionnement qui sera décrit plus loin.Their opening and closing are actuated by an actuation mechanism which will be described later.

Elles sont fixées à un profilé commun 4, par exemple métallique et au potentiel de la terre. Ce profilé 4 peut tourner selon l'axe 5, de préférence horizontal, pour assurer la fonction sectionnement de l'appareil. Pour ce faire, l'axe 5 est pivotant sur un châssis fixe 6. Dans le profilé 4 est logé un arbre rotatif 7 d'actionnement des chambres.They are fixed to a common profile 4, for example metallic and to the earth potential. This profile 4 can rotate along the axis 5, preferably horizontal, to ensure the disconnecting function of the device. To do this, the axis 5 is pivoted on a fixed frame 6. In the profile 4 is housed a rotary shaft 7 for actuating the chambers.

Le mécanisme d'actionnement comporte ledit arbre d'actionnement 7 supportant, pour chaque chambre 1, 2, 3, une bielle 8 articulée selon un axe 9 de préférence horizontal, à une extrémité d'une tige de manoeuvre 10 dont l'autre extrémité est articulée à une extrémité d'un levier de renvoi 11 pivotant sur un axe fixe 12 et actionnant le contact mobile de chaque chambre 1, 2, 3.The actuation mechanism comprises said actuation shaft 7 supporting, for each chamber 1, 2, 3, a connecting rod 8 articulated along an axis 9 preferably horizontal, at one end of an operating rod 10, the other end is articulated at one end of a return lever 11 pivoting on a fixed axis 12 and actuating the movable contact of each chamber 1, 2, 3.

Le contact mobile de chaque chambre est électriquement relié à une première mâchoire de connexion 13 et son contact fixe est reliée électriquement à une seconde mâchoire de connexion 14. Ses mâchoires 13, 14 viennent s'embrocher dans des jeux de barres, lorsque l'appareil est en position non sectionnée, le jeu de barres 17 associé aux mâchoires 13 constituant l'arrivée du courant et le jeu de barres 18 associé aux mâchoires 14 constituant la sortie du courant.The movable contact of each chamber is electrically connected to a first connection jaw 13 and its fixed contact is electrically connected to a second connection jaw 14. Its jaws 13, 14 are plugged into busbars, when the device is in the uncut position, the busbar 17 associated with the jaws 13 constituting the current inlet and the busbar 18 associated with the jaws 14 constituting the current outlet.

En ce qui concerne ces premiers éléments techniques, le disjoncteur auto-sectionneur est identique à celui décrit dans la demande de brevet antérieure FR-2 683 939.With regard to these first technical elements, the self-disconnecting circuit breaker is identical to that described in the prior patent application FR-2 683 939.

A une de ses extrémités, l'arbre 4 comporte une bielle supplémentaire 8' dont l'axe 9' est relié à une tringle 15 entraîné par un dispositif de commande 16, qui entraîne donc l'arbre 4 en rotation assurant l'ouverture et la fermeture des contacts des chambres de coupure 1, 2, 3. L'axe 9' est, avantageusement, aligné à l'axe 9 des bielles 8 du dispositif d'actionnement.At one of its ends, the shaft 4 comprises an additional connecting rod 8 'whose axis 9' is connected to a rod 15 driven by a control device 16, which therefore drives the shaft 4 in rotation ensuring the opening and closing the contacts of the interrupting chambers 1, 2, 3. The axis 9 ′ is advantageously aligned with the axis 9 of the connecting rods 8 of the actuating device.

sur la figure 1, les chambres de coupure 1, 2, 3 sont représentées en position ouverte et en position embrochée. En traits pointillés, est représentée la bielle 8' d'extrémité en position fermée des chambres de coupures 1, 2, 3.in FIG. 1, the interrupting chambers 1, 2, 3 are shown in the open position and in the plugged-in position. In dotted lines, the connecting rod 8 ′ is shown in the closed position of the interrupting chambers 1, 2, 3.

Le dispositif de commande 16 est fixe. Le passage de la position embrochée à la position sectionnée et inversement se fait par rotation seule de la poutre 4 et donc des chambres 1, 2, 3 et de leur dispositif d'actionnement solidaires de la poutre 4.The control device 16 is fixed. The transition from the plugged-in position to the sectioned position and Conversely, the beam 4 and only the chambers 1, 2, 3 and their actuation device integral with the beam 4 rotate only by rotation.

En position ouverte des contacts des chambres de coupure, comme représentée sur la figure 1, l'axe 5 et l'axe 9' sont alignés. Par cette caractéristique est réalisé un auto-verrouillage du disjoncteur. En effet, ce n'est que dans cette position d'alignement des axes 5 et 9' que la rotation de l'ensemble poutre 4/chambres de coupure 1, 2, 3 peut être réalisée. Il est donc impossible de passer de la position embrochée à la position sectionnée, lorsque les contacts des chambres de coupure sont fermés.In the open position of the contacts of the interrupting chambers, as shown in FIG. 1, the axis 5 and the axis 9 'are aligned. By this characteristic is achieved a self-locking of the circuit breaker. Indeed, it is only in this position of alignment of the axes 5 and 9 ′ that the rotation of the beam 4 / breaking chambers 1, 2, 3 assembly can be carried out. It is therefore impossible to pass from the plugged-in position to the sectioned position, when the contacts of the switching chambers are closed.

Les figures 2 et 3 illustrent cet effet d'auto-verrouillage.Figures 2 and 3 illustrate this self-locking effect.

La figure 2 est une vue schématique de côté du disjoncteur en position embrochée et la figure 3 est une vue analogue en position sectionnée.Figure 2 is a schematic side view of the circuit breaker in the plugged-in position and Figure 3 is a similar view in the sectioned position.

Dans la position représentée en traits pleins, les contacts des chambres de coupure sont en position ouverte et les axes 5 et 9' sont alignés. La poutre 4 et les chambres de coupure 1, 2, 3 solidaires de celle-ci peuvent alors être tournées dans le sens de la flèche pour passer de la position embrochée à la position sectionnée représentée sur la figure 3. Les leviers 8 et 8' tournent alors autour de leur axe 9 et 9' en même temps que la poutre tourne autour de l'axe 5.In the position shown in solid lines, the contacts of the switching chambers are in the open position and the axes 5 and 9 ′ are aligned. The beam 4 and the breaking chambers 1, 2, 3 integral with the latter can then be turned in the direction of the arrow to pass from the plugged-in position to the sectioned position shown in FIG. 3. The levers 8 and 8 ' then rotate around their axis 9 and 9 'at the same time as the beam rotates around axis 5.

En position fermée des contacts des chambres de coupure 1, 2, 3, le levier 8' et son axe 9' sont dans la position représentée en pointillés. L'axe 9' n'est pas aligné avec l'axe 5 qui est fixe et il est donc impossible de déplacer la poutre 4 et les chambres de coupure. Il y a donc auto-verrouillage en position embrochée lorsque les contacts des chambres de coupure sont en position fermée.In the closed position of the contacts of the interrupting chambers 1, 2, 3, the lever 8 'and its axis 9' are in the position shown in dotted lines. The axis 9 'is not aligned with the axis 5 which is fixed and it is therefore impossible to move the beam 4 and the breaking chambers. There is therefore self-locking in the plugged-in position when the contacts of the switching chambers are in the closed position.
