Description

La présente invention se rapporte à un disjoncteur à haute ou moyenne tension comprenant dans une enveloppe remplie de gaz diélectrique, en particulier de SF6, un premier contact d'arc relié à une première prise de courant, un second contact d'arc relié à une seconde prise de courant et mobile dans un cylindre fixe, où il forme avec un piston une chambre de compression.The present invention relates to a high or medium voltage circuit breaker comprising, in an envelope filled with dielectric gas, in particular SF6, a first arcing contact connected to a first socket, a second arcing contact connected to a second outlet and mobile in a fixed cylinder, where it forms with a piston a compression chamber.

Généralement, dans de tels disjoncteurs, le premier contact et le piston sont fixes, la séparation des contacts et la mise en compression du gaz diélectrique dans la chambre de compression se faisant par simple déplacement du second contact mobile.Generally, in such circuit breakers, the first contact and the piston are fixed, the separation of the contacts and the compression of the dielectric gas in the compression chamber being done by simple displacement of the second movable contact.

Le brevet français FR - 2 491 675 divulgue un dispositif de coupure dont les contacts sont déplacés dans des sens opposés, afin d'augmenter la vitesse de séparation des contacts sans augmenter la vitesse du contact mobile. Les moyens d'actionnement sont constitués d'un agencement de tirants et de bielles.French patent FR-2 491 675 discloses a breaking device whose contacts are moved in opposite directions, in order to increase the speed of separation of the contacts without increasing the speed of the movable contact. The actuating means consist of an arrangement of tie rods and connecting rods.

Le brevet français FR - 2 320 626 décrit un disjoncteur à piston et contact mobiles par l'intermédiaire de tringles, le contact fixe étant solidaire du cylindre formant chambre de soufflage.French patent FR-2 320 626 describes a circuit breaker with piston and contact movable by means of rods, the fixed contact being integral with the cylinder forming blowing chamber.

Dans un disjoncteur à gaz diélectrique tel que le SF6, une vitesse de séparation élevée des contacts et une course importante pour tenir la tension sont recherchées pour couper les courants capacitifs. Pour couper les courants de court-circuit et de défaut kilométrique, il faut une grande pression de soufflage ainsi qu'une montée en pression rapide.In a dielectric gas circuit breaker such as SF6, a high speed of separation of the contacts and a large stroke to hold the voltage are sought to cut the capacitive currents. To cut short-circuit and mileage fault currents, a high blowing pressure and a rapid pressure build-up are required.

Le but de l'invention est de permettre une coupure correcte de ces types de courant, tout en utilisant une énergie de manoeuvre la plus réduite possible.The object of the invention is to allow correct cutting of these types of current, while using the lowest possible operating energy.

Pour ce faire, selon l'invention, le premier contact d'arc et le piston sont mobiles, le disjoncteur comportant des moyens d'actionnement du premier contact d'arc dans le sens opposé à celui du déplacement du second contact et du piston dans le sens opposé à celui du déplacement du second contact.To do this, according to the invention, the first arcing contact and the piston are movable, the circuit breaker comprising means for actuating the first arcing contact in the direction opposite to that of the displacement of the second contact and of the piston in the opposite direction to that of the displacement of the second contact.

L'on obtient ainsi une vitesse de séparation importante des contacts, par coopération des déplacements des deux contacts, sans nécessité d'une vitesse excessive de l'un des contacts, et une montée en pression rapide et élevée, par coopération des déplacements du second contact et du piston dans le cylindre fixe.This results in a high speed of separation of the contacts, by cooperation of the movements of the two contacts, without the need for excessive speed of one of the contacts, and a rapid and high pressure build-up, by cooperation of the movements of the second. contact and piston in the fixed cylinder.

De plus, l'énergie de manoeuvre peut être minimalisée. La pièce de poids élevé, que constitue le second contact, peut avoir une vitesse et une course relativement faibles. Le cylindre est, quant à lui, fixe. La pièce légère, que constitue le premier contact, peut avoir une vitesse et une course relativement élevées.In addition, the operating energy can be minimized. The heavy piece, which is the second contact, can have a relatively low speed and stroke. The cylinder is fixed. The light part, which constitutes the first contact, can have a relatively high speed and stroke.

Grâce à l'invention, le disjoncteur peut être rempli de gaz diélectrique à basse pression, ce qui améliore sa tenue aux grands froids.Thanks to the invention, the circuit breaker can be filled with dielectric gas at low pressure, which improves its resistance to very cold weather.

Il résulte, de plus, de l'invention une faible usure des contacts et une faible pollution du gaz diélectrique.In addition, the invention results in low wear of the contacts and low pollution of the dielectric gas.

De préférence, les moyens d'actionnement des contacts et du piston sont à commande unique et, plus particulièrement, cette commande est à arbre rotatif.Preferably, the means for actuating the contacts and the piston are of single control and, more particularly, this control has a rotary shaft.

Selon des caractéristiques constructives, l'extrémité supérieure du premier contact est logée dans un cylindre creux solidaire de l'enveloppe, un ressort poussant le contact vers le haut, et est actionnée par une tige traversant deux lumières oblongues du cylindre, reposant sur l'extrémité supérieure du premier contact et reliant deux tirants dont le déplacement est commandé par l'arbre.According to constructive characteristics, the upper end of the first contact is housed in a hollow cylinder integral with the envelope, a spring pushing the contact upwards, and is actuated by a rod passing through two oblong holes in the cylinder, resting on the upper end of the first contact and connecting two tie rods whose movement is controlled by the shaft.

Par ailleurs, les moyens d'actionnement du second contact et du piston sont constitués de bielles articulées.Furthermore, the means for actuating the second contact and the piston consist of articulated connecting rods.

L'invention est décrite ci-après plus en détail à l'aide de dessins ne représentant qu'un mode de réalisation.The invention is described below in more detail using drawings representing only one embodiment.

La figure 1 est une vue en coupe longitudinale d'un disjoncteur conforme à l'invention, en position fermée.Figure 1 is a longitudinal sectional view of a circuit breaker according to the invention, in the closed position.

La figure 2 est une vue en coupe longitudinale du disjoncteur, en position ouverte.Figure 2 is a longitudinal sectional view of the circuit breaker, in the open position.

La figure 3 est une vue en coupe longitudinale (perpendiculairement aux précédentes) du disjoncteur, en position fermée.Figure 3 is a longitudinal sectional view (perpendicular to the previous) of the circuit breaker, in the closed position.

Le disjoncteur comprend dans une enveloppe 1 un premier contact d'arc 2 relié à une première prise de courant 3, un second contact d'arc 4 relié à une seconde prise de courant 5 et mobile dans un cylindre fixe 6 où il forme avec un piston 7 une chambre de soufflage 8.The circuit breaker comprises in a casing 1 a first arcing contact 2 connected to a first socket 3, a second arcing contact 4 connected to a second socket 5 and movable in a fixed cylinder 6 where it forms with a piston 7 a blowing chamber 8.

Le disjoncteur représenté est à enveloppe isolante 1 et pour plus de clarté, les contacts permanents ne sont pas représentés; ils peuvent être internes ou externes à l'enveloppe, de façon connue. Le disjoncteur peut être destiné à la haute ou à la moyenne tension.The circuit breaker shown is with an insulating casing 1 and for clarity, the permanent contacts are not shown; they can be internal or external to the envelope, in a known manner. The circuit breaker can be intended for high or medium voltage.

Le premier contact d'arc 2 et le piston 7 sont mobiles par l'intermédiaire de moyens d'actionnement assurant le déplacement du premier contact d'arc 2 dans le sens oppose à celui du déplacement du second contact 4 et le déplacement du piston 7 dans le sens opposé à celui du déplacement du second contact 4.The first arcing contact 2 and the piston 7 are movable by means of actuation means ensuring the displacement of the first arcing contact 2 in the opposite direction to that of the displacement of the second contact 4 and the displacement of the piston 7 in the opposite direction to that of the displacement of the second contact 4.

Ces moyens d'actionnement sont à commande unique à arbre rotatif 9. A cet arbre 9 horizontal disposé en partie basse du disjoncteur, est liée en rotation un levier 10 portant à l'une de ses extrémités un tourillon 11 et formant à son autre extrémité une fourche supportant un axe 12.These actuating means are a single control rotary shaft 9. To this horizontal shaft 9 disposed in the lower part of the circuit breaker, is linked in rotation a lever 10 carrying at one of its ends a pin 11 and forming at its other end a fork supporting an axis 12.

Sur le tourillon 11, à ses extrémités, sont montés rotatifs deux bielles 13, en matériau isolant, tournant respectivement sur des tenons 14 horizontaux solidaires du piston 7 pourvu d'un clapet de remplissage, pour l'enclenchement.On the pin 11, at its ends, are rotatably mounted two connecting rods 13, made of insulating material, rotating respectively on horizontal studs 14 integral with the piston 7 provided with a filling valve, for engagement.

Sur le levier 10, à proximité de la liaison avec le tourillon 11, sont fixés deux axes 15 horizontaux sur lesquels tournent deux tirants 16 ,en matériau isolant, reliés à leur extrémité supérieure par une tige 17 horizontale, en matériau isolant, entraînant le premier contact 2 par l'intermédiaire d'un agencement décrit plus loin. Ces tirants 16 ne travaillant qu'en traction sont de section simple par exemple ronde.On the lever 10, near the connection with the pin 11, two horizontal axes 15 are fixed on which two tie rods 16 turn, made of insulating material, connected at their upper end by a horizontal rod 17, made of insulating material, driving the first contact 2 via an arrangement described below. These tie rods 16 working only in traction are of simple section, for example round.

Sur l'axe 12, est monté une bielle 18 , en matériau isolant, lié à un axe 19 horizontal solidaire du second contact 4.On the axis 12, a connecting rod 18 is mounted, made of insulating material, linked to a horizontal axis 19 integral with the second contact 4.

L'extrémité supérieure du premier contact 2 comporte une bride annulaire logée dans un cylindre 19 creux solidaire de la première prise de courant 3. Un ressort 20 en appui entre cette bride et un rebord inférieur du cylindre 19 pousse le contact 2 vers le haut. La tige 17 traverse deux lumières oblongues du cylindre 19 et repose sur l'extrémité supérieure du premier contact 2.The upper end of the first contact 2 has an annular flange housed in a hollow cylinder 19 integral with the first socket 3. A spring 20 bearing between this flange and a lower edge of the cylinder 19 pushes the contact 2 upwards. The rod 17 passes through two oblong slots in the cylinder 19 and rests on the upper end of the first contact 2.

Sur la figure 1, le disjoncteur est en position fermée. Dans cette position de l'arbre de commande 9, la bielle 18 est en position haute poussant le second contact 4 en position haute, ainsi que sa bride annulaire portant la buse de soufflage et coulissante dans le cylindre fixe 6 par l'intermédiaire de contacts glissants; cette bride est alors à proximité de l'extrémité supérieure du cylindre 6.In Figure 1, the circuit breaker is in the closed position. In this position of the control shaft 9, the connecting rod 18 is in the high position pushing the second contact 4 in the high position, as well as its annular flange carrying the blowing nozzle and sliding in the fixed cylinder 6 via contacts slippery; this flange is then near the upper end of the cylinder 6.

Les bielles 13 sont, par contre, en position basse, tirant le piston 7 en position basse à proximité de l'extrémité inférieure du cylindre 6. Le volume de compression 8 est alors maximal.The connecting rods 13 are, on the other hand, in the low position, pulling the piston 7 in the low position near the lower end of the cylinder 6. The compression volume 8 is then maximum.

Les tirants 16 sont en conséquence également en position basse, la tige 17 poussant le premier contact 2 vers le bas à l'encontre de la sollicitation du ressort 20.The tie rods 16 are consequently also in the low position, the rod 17 pushing the first contact 2 downwards against the bias of the spring 20.

Lors de l'ouverture, l'arbre de commande 9 est tourné dans le sens des aiguilles d'une montre selon les figures 1 et 2, et le second contact 4 tiré vers le bas par la bielle 18, le piston 7 poussé vers le haut par les bielles 13 et le premier contact 2 poussé vers le haut par le ressort 20. Le volume de la chambre de soufflage 8 est ainsi diminué rapidement et la montée en pression non seulement élevée mais rapide. Les contacts 2 et 4 sont ainsi rapidement séparés. Le passage de la position fermée (figure 1) à la position ouverte (figure 2) est réalisé par une faible rotation de l'arbre de commande 9, sur environ 45° et est donc particulièrement rapide.When opening, the control shaft 9 is turned clockwise according to FIGS. 1 and 2, and the second contact 4 pulled down by the connecting rod 18, the piston 7 pushed towards the high by the connecting rods 13 and the first contact 2 pushed upwards by the spring 20. The volume of the blowing chamber 8 is thus rapidly reduced and the pressure rise not only high but rapid. Contacts 2 and 4 are thus quickly separated. The transition from the closed position (Figure 1) to the open position (Figure 2) is achieved by a slight rotation of the control shaft 9, about 45 ° and is therefore particularly rapid.
