Abstract

The circuit breaker, comprising a basically cylindrical shell (26) closed by a base (22) at one end, and an inner sleeve forming central and annular passages that are connected adjacent to the base, has two diametrically opposite gas discharge apertures in the shell that are located in the horizontal plane. The apertures are situated at a certain distance from the end of the annular passage and are separated by radial partitions that force the gas to pass as far as the end of the annular passage before exiting through the apertures.

Description

L'invention concerne un échappement de gaz pour disjoncteur, comprenant une enveloppe de forme générale cylindrique fermée par un fond à une extrémité et présentant des ouvertures pour l'échappement du gaz, un fourreau disposé dans l'enveloppe pour délimiter, intérieurement, un passage central et extérieurement, avec l'enveloppe, un passage annulaire entourant le passage central, une communication étant prévue dans le fourreau à proximité du fond pour réaliser une communication du passage central du fourreau vers le passage annulaire.The invention relates to a gas escape for a circuit breaker, comprising a casing of generally cylindrical shape closed by a bottom at one end and having openings for the escape of the gas, a sheath disposed in the casing for delimiting, internally, a passage central and outer, with the casing, an annular passage surrounding the central passage, a communication being provided in the sleeve near the bottom to achieve a communication of the central passage of the sleeve to the annular passage.

On connaît déjà ( WO 03/096366 ) un appareil électrique comportant un échappement de ce type (voir figure 7). L'appareil électrique présente une zone de coupure dans laquelle un gaz est généré par un arc dans une tuyère. Ce gaz s'écoule à travers un canal dans un dispositif de refroidissement qui présente la forme d'un tube de refroidissement. Ce tube présente une paroi épaisse dans laquelle de nombreux orifices traversant sont prévus pour le passage du gaz. Un dispositif de ce type conduit à une mauvaise utilisation du volume enfermé dans l'échappement que les gaz chauds générés par la coupure doivent chasser avant d'atteindre la sortie de l'échappement qui comporte des arêtes vives qui conduisent à des augmentation de champ telles qu'un arc risque de s'amorcer à partir de ces arêtes vers la cuve métallique dans laquelle l'appareil électrique est logé.We already know ( WO 03/096366 ) an electrical appliance with an exhaust of this type (see Figure 7). The electrical apparatus has a cutoff zone in which a gas is generated by an arc in a nozzle. This gas flows through a channel in a cooling device which is in the form of a cooling tube. This tube has a thick wall in which many through holes are provided for the passage of gas. A device of this type leads to a misuse of the volume enclosed in the exhaust that the hot gases generated by the cut must chase before reaching the exhaust outlet which has sharp edges that lead to field increases such as that an arc may start from these edges to the tank in which the electrical apparatus is housed.

Par ailleurs, des poussières et des particules s'amassent au fond de la cuve parmi lesquelles peuvent se trouver des particules électriquement conductrices. Le champ électrique qui reigne entre la surface extérieur de l'échappement et la surface intérieure de la cuve suffit parfois à faire bouger ou même orienter verticalement ces particules conductrices. A partir du moment où ces particules conductrices s'orientent verticalement elles peuvent avoir des effets de pointe. Cet effet de pointe favorise l'amorçage d'arcs entre l'échappement de l'appareil sous tension et la cuve métallique reliée à la terre. Le tube de refroidissement percé d'orifices est une pièce axisymétrique de telle sorte que les gaz sont soufflés dans toutes les directions, notamment vers le haut et vers le bas. Au moment où le gaz est engendré, il souffle dans cet amas de particules qui se mettent alors à virevolter. Ceci favorise le redressement des particules conductrices et donc l'amorçage.In addition, dust and particles accumulate at the bottom of the tank, among which electrically conductive particles may be found. The electric field that reigns between the outer surface of the exhaust and the inner surface of the tank is sometimes enough to move or even vertically orient these conductive particles. From the moment these conductive particles are oriented vertically they can have peak effects. This peak effect favors arcing between the exhaust of the live device and the metal tank connected to the earth. The cooling tube pierced with orifices is an axisymmetrical piece so that the gases are blown in all directions, in particular upwards and downwards. At the moment when the gas is generated, it blows into this mass of particles that begin to twirl. This favors the recovery of the conductive particles and thus the priming.

Avant que l'échappement ne soit complètement rempli de gaz chaud, une partie de ce gaz quitte l'échappement et se fraie un chemin vers la cuve. Etant donné que le gaz chaud est beaucoup plus conducteur que le gaz froid, des amorçages tardifs entre l'échappement et la cuve en sont la conséquence si la quantité de gaz chaud quittant l'échappement est significative.Before the exhaust is completely filled with hot gas, some of this gas leaves the exhaust and makes its way to the tank. Since the hot gas is much more conductive than the cold gas, late ignitions between the exhaust and the tank are the consequence if the amount of hot gas leaving the exhaust is significant.

Par ailleurs la partie du tube de refroidissement percée d'orifices qui peut être traversée par des gaz chauds est axialement longue.Furthermore, the portion of the cooling tube pierced with orifices which can be traversed by hot gases is axially long.

Elle s'étend des repères 114a à 115. Il existe donc deux chemins vers la sortie de l'échappement qui diffèrent nettement en logueur. Partant toujours du repère 108 pour aboutir au repère 112, le gaz qui traverse le tube de refroidissement au repère 114a atteint la sortie 112 après un chemin nettement plus court. C'est ce chemin le plus court qui force à augmenter le volume total du gaz contenu dans l'échappement. Il y est donc proche du repère 115 du gaz froid qui n'est poussé hors de l'échappement que tardivement.It extends from the markers 114a to 115. There are therefore two paths to the exit of the exhaust which clearly differ in logger. Always starting from the reference 108 to reach the mark 112, the gas passing through the cooling tube at 114a reaches the exit 112 after a significantly shorter path. It is this shortest path that forces to increase the total volume of gas contained in the exhaust. It is therefore close to the mark 115 of the cold gas that is pushed out of the exhaust late.

L'invention a pour objet un échappement qui remédie à ces inconvénients. Ces buts sont atteints, conformément à l'invention, par le fait que l'enveloppe comprend deux ouvertures diamétralement opposées situées dans un plan horizontal.The invention relates to an escapement that overcomes these disadvantages. These objects are achieved, according to the invention, in that the envelope comprises two diametrically opposed openings located in a horizontal plane.

Grâce à cette caractéristique l'échappement ne comporte pas, comme dans l'art antérieur, un grand nombre de petits orifices présentant une résistance à l'écoulement des gaz, mais au contraire des ouvertures de grand diamètre dont les rayons de courbure peuvent être rendus suffisamment grands pour empêcher l'apparition d'une augmentation de champ électrique. Les rayons de courbure sont compatibles à la fois avec l'échappement facile des gaz et une tenue électrique vis-à-vis de la cuve qui est proche. D'autre part, étant donné que les ouvertures sont dans un plan horizontal les particules de poussières lourdes et de produits dérivés causés par les interruption du courant ne sont pas soufflées dans une zone de la cuve où d'autres particules se sont déjà accumulées.Thanks to this characteristic, the escapement does not comprise, as in the prior art, a large number of small orifices having resistance to the flow of gases, but unlike large diameter openings whose radii of curvature can be rendered large enough to prevent the occurrence of an electric field increase. The radii of curvature are compatible with both the easy escape of the gases and an electrical resistance vis-à-vis the tank that is close. On the other hand, since the openings are in a horizontal plane the particles of heavy dust and Derivatives caused by current interruptions are not blown into an area of the tank where other particles have already accumulated.

Selon l'invention, les particules ne sont pas expulsées à l'extérieur de l'échappement parce que le gaz change plusieurs fois de direction avant d'atteindre la sortie de l'échappement. Dans chaque tournant les forces centrifuges agissent sur les particules lourdes pour les séparer du courant principal, comme dans un cyclone.According to the invention, the particles are not expelled outside the exhaust because the gas changes direction several times before reaching the outlet of the exhaust. In each turn the centrifugal forces act on the heavy particles to separate them from the main stream, as in a cyclone.

De préférence, la section de passage offerte au gaz est monotone et progressivement croissante.Preferably, the passage section offered to gas is monotonous and progressively increasing.

Grâce à cette caractéristique la section de passage disponible pour l'écoulement du gaz augmente de façon monotone depuis la tuyère (le divergent) jusqu'à une valeur maximale. De cette manière, on évite ainsi les vortex qui créent une contre pression nuisible et diminuent les performances de la coupure, on évite aussi les poches de gaz froid, c'est-à-dire une partie du volume de l'échappement qui ne contient pas de gaz chaud.Thanks to this characteristic, the passage section available for the flow of gas increases monotonically from the nozzle (the divergent) to a maximum value. In this way, the vortexes that create a harmful pressure against and reduce the performance of the cut are thus avoided, the pockets of cold gas, that is to say a part of the volume of the exhaust which contains no hot gas.

On ralentit le gaz chaud et on permet aux particules dont certaines sont conductrices de rester en partie dans l'échappement.The hot gas is slowed down and the particles, some of which are conductive, are allowed to remain partly in the exhaust.

De préférence, la section de passage offerte au gaz ne varie pas de plus d'un facteur quatre à chaque augmentation de section.Preferably, the passage section offered to the gas does not change by more than a factor of four at each section increase.

Dans un mode de réalisation préféré, les deux ouvertures formées dans l'enveloppe sont espacées d'une certaine distance d'un fond du passage annulaire et quatre cloisons radiales sont prévues pour, d'une part, caréner les ouvertures formées dans l'enveloppe et, d'autre part, délimiter des passages de gaz isolés des ouvertures afin d'obliger le gaz à aller jusqu'au fond du passage annulaire avant de pouvoir sortir par les ouvertures.In a preferred embodiment, the two openings formed in the envelope are spaced a certain distance from a bottom of the annular passage. and four radial partitions are provided for, on the one hand, fairing the openings formed in the envelope and, on the other hand, delimit gas passages insulated openings to force the gas to go to the bottom of the passage ring before being able to exit through the openings.

Grâce à cette caractéristique, le gaz suit deux trajets différents pour sortir de l'échappement. Les courants de gaz balayent la totalité du volume intérieur de l'échappement et on évite qu'il y ait des poches de gaz froid qui restent dans l'appareil.With this feature, the gas follows two different paths out of the exhaust. The gas streams sweep the entire interior volume of the exhaust and prevents pockets of cold gas remaining in the apparatus.

De préférence, les ouvertures formées dans l'enveloppe s'étendent sur environ un tiers de la périphérie de l'enveloppe.Preferably, the openings formed in the envelope extend over about one-third of the periphery of the envelope.

Dans une réalisation particulière, la communication prévue dans le fourreau à proximité du fond pour réaliser une communication du passage central du fourreau vers le passage annulaire est constituée de quatre trous.In a particular embodiment, the communication provided in the sleeve near the bottom to make a communication of the central passage of the sleeve towards the annular passage consists of four holes.

D'autres caractéristiques et avantages de l'invention apparaîtront encore à la lecture de la description qui suit d'un exemple de réalisation donné à titre illustratif en référence aux figures annexées. Sur ces figures:

  • la figure 7 est une vue en coupe d'un disjoncteur de l'art antérieur.
Other features and advantages of the invention will become apparent upon reading the following description of an exemplary embodiment given by way of illustration with reference to the appended figures. In these figures:
  • FIG. 1 is a sectional elevational view of a circuit breaker comprising a gas exhaust according to the present invention;
  • Figure 2 is a horizontal sectional view of the circuit breaker of Figure 1;

Les figures 1 et 2 représentent schématiquement un appareillage électrique de coupure, tel qu'un disjoncteur.Figures 1 and 2 show schematically an electrical switchgear, such as a circuit breaker.

L'appareillage électrique est logé dans une cuve 4 remplie d'un gaz isolant 6 tel que par exemple le SF6. Le disjoncteur comporte un contact d'arc mobile 8 ainsi qu'un contact d'arc fixe 10 monté sur trois pieds 11. Lors d'une coupure, un arc apparaît entre les contacts mobile 8 et fixe 10. Pour cette raison, l'espace situé entre le contact fixe et le contact mobile est entouré d'une buse ou tuyère isolante 12 présentant une extrémité 14 évasée. La fonction de la tuyère 12 est de canaliser le gaz ou plasma engendré par l'arc électrique entre le contact fixe et le contact mobile. Le contact fixe 10 est entouré par un fourreau 16 dans lequel la partie évasée 14 de la tuyère 12 coulisse à la manière d'un piston. Une extrémité du fourreau 16 est fermée par un fond constitué par dôme 18. A proximité du dôme 18 le fourreau est percé de quatre orifices 20 de section sensiblement rectangulaire. Extérieurement au dôme 18 on trouve une coquille 22 de forme arrondie présentant un grand rayon de courbure et dont la forme rappelle celle d'un oeuf.The electrical equipment is housed in a tank 4 filled with an insulating gas 6 such as, for example, SF 6 . The circuit breaker comprises a movable arcing contact 8 and a fixed arcing contact 10 mounted on three legs 11. During a break, an arc appears between the movable contacts 8 and fixed 10. For this reason, the space between the fixed contact and the movable contact is surrounded by an insulating nozzle or nozzle 12 having a flared end 14. The function of the nozzle 12 is to channel the gas or plasma generated by the electric arc between the fixed contact and the movable contact. The fixed contact 10 is surrounded by a sleeve 16 in which the flared portion 14 of the nozzle 12 slides in the manner of a piston. One end of the sheath 16 is closed by a bottom consisting of a dome 18. In the vicinity of the dome 18 the sheath is pierced with four orifices 20 of substantially rectangular section. Externally to the dome 18 is a shell 22 of rounded shape presenting a large radius of curvature and whose shape is reminiscent of an egg.

Extérieurement, le fourreau est entouré une enveloppe 26 qui a été représentée en perspective sur la figure 3. A la partie droite de la figure on peut apercevoir, débouchant de l'enveloppe 26, l'extrémité droite du fourreau 16 comportant les quatre trous de passage 20 (la coquille 22 étant retirée). L'enveloppe 26 présente une forme cylindrique coaxiale à l'axe XX du disjoncteur. A sa partie supérieure un conducteur électrique 28 est relié au disjoncteur. Deux ouvertures 30 dirigées horizontalement sont formées dans l'enveloppe 26 (une seule ouverture est visible sur la figure 3). Pour réaliser les ouvertures 30 on a formé deux cloisons radiales 32, 34, 36, 38 pour chaque ouverture 30 (voir figures 5 et 6). Chaque cloison est dirigée radialement vers l'intérieur et s'étend jusqu'à la surface périphérique extérieure du fourreau 16 dont on peut apercevoir une partie à travers l'ouverture 30 sur la figure 3.Externally, the sheath is surrounded by an envelope 26 which has been shown in perspective in FIG. 3. At the right-hand part of the figure, the right end of the sheath 16 with the four holes of the sheath 16 can be seen emerging from the envelope 26. passage 20 (the shell 22 being removed). The envelope 26 has a cylindrical shape coaxial with the axis XX of the circuit breaker. At its upper part an electrical conductor 28 is connected to the circuit breaker. Two horizontally directed openings 30 are formed in the envelope 26 (only one opening is visible in FIG. 3). To make the openings 30, two radial partitions 32, 34, 36, 38 have been formed for each opening 30 (see FIGS. 5 and 6). Each partition is directed radially inward and extends to the outer peripheral surface of the sleeve 16, a portion of which can be seen through the opening 30 in FIG.

Le fourreau délimite, intérieurement, un passage central 40 et, extérieurement, un passage annulaire 42 avec l'enveloppe 26. Le passage central 40 et le passage annulaire 42 communiquent l'un avec l'autre par l'intermédiaire des quatre trous 20 formés à l'extrémité du fourreau proche du dôme 18. On réalise ainsi un parcours en labyrinthe avantageux comme on l'a expliqué précédemment, pour permettre le dépôt des particules lourdes en suspension dans le courant de gaz et d'autre part, pour réaliser une section monotone croissante afin d'éviter d'emprisonner des poches de gaz froid dans l'échappement, particulièrement dans le passage central 40. Comme on peut le voir plus particulièrement sur la figure 4, le passage annulaire 42 est scindé en deux parties par les deux paires de cloisons radiales 32 et 34 d'une part, 36 et 38 d'autre part. Une partie de ce canal annulaire communique directement avec les ouvertures 30 de telle sorte que le gaz peut s'échapper directement. La partie du passage annulaire comprise entre les cloisons radiales 32 et 38 d'une part, la partie du passage comprise entre les cloisons 34 et 36 d'autre part constituent deux passages de gaz isolés des ouvertures 30 afin de contraindre la partie du gaz qui passe par ces passages à aller jusqu'à un fond 44 du passage annulaire opposé à la coquille 22. De préférence, la section de passage des trous 30 est environ un tiers de la section des canaux isolés situés entre les cloisons radiales 32 et 38 d'une part et 34 et 36 d'autre part. En d'autres termes, la section de passage des canaux isolés est sensiblement deux fois supérieure à celle des orifices de sortie 30.The sleeve defines, internally, a central passage 40 and, externally, an annular passage 42 with the envelope 26. The central passage 40 and the annular passage 42 communicate with each other via the four holes 20 formed at the end of the sheath close to the dome 18. This provides a labyrinth route advantageous as explained above, to allow the deposition of heavy particles suspended in the gas stream and secondly, to achieve a growing monotonous section to avoid trapping pockets of cold gas in the exhaust, particularly in the central passage 40. As can be seen more particularly in Figure 4, the annular passage 42 is split into two parts by the two pairs of radial partitions 32 and 34 on the one hand, 36 and 38 on the other hand. Part of this annular channel communicates directly with the openings 30 so that the gas can escape directly. The portion of the annular passage between the radial partitions 32 and 38 on the one hand, the portion of the passage between the partitions 34 and 36 on the other hand constitute two gas passages isolated from the openings 30 in order to constrain the part of the gas which passes through these passages to a bottom 44 of the annular passage opposite the shell 22. Preferably, the passage section of the holes 30 is about one third of the section of the isolated channels located between the radial partitions 32 and 38 d on the one hand and 34 and 36 on the other. In other words, the passage section of the insulated channels is substantially twice that of the outlet ports 30.

Grâce à ces formes la section de passage offerte au gaz est monotone croissante. En effet, la section du canal annulaire 42 est sensiblement supérieure à la section du passage central 40. D'autre part, dans tous les points du parcours, les rayons de courbure sont importants ce qui facilite la circulation des gaz. Les cloisons radiales 32 sont elles-mêmes prévues avec des rayons de courbure importants par rapport à la surface périphérique extérieure de l'enveloppe 26 de telle sorte qu'en aucun point n'apparaît une concentration de champ électrique.Thanks to these forms the passage section offered to gas is monotonous growing. Indeed, the section of the annular channel 42 is substantially greater than the cross section of the central passage 40. On the other hand, in all points of the path, the radii of curvature are important which facilitates the flow of gas. The radial partitions 32 themselves are provided with large radii of curvature relative to the outer peripheral surface of the envelope 26 so that at no point does an electric field concentration appear.

Le fonctionnement de ce dispositif est le suivant. Lors d'une coupure, un arc apparaît entre le contact mobile 8 et le contact fixe 10. Une quantité de gaz chaud est engendrée. Elle se propage à partir de la tuyère 12 dans le fourreau 16 qu'elle parcourt selon toute sa longueur jusqu'à parvenir jusqu'au dôme 18 sur lequel elle s'oriente perpendiculairement de manière à passer par les orifices 20. Le jet de gaz frappe alors les parties arrondies de la coquille 22 réalisant un premier changement de direction. Le gaz parcourt alors le passage annulaire 42. Une partie du gaz sort directement par les orifices 30 tandis que la partie restant du gaz s'écoule jusqu'au fond 44 dans lequel il subit un second changement de direction. Le gaz retourne alors vers les orifices 30 en passant pardessus les cloisons radiales 32, 34, 36, 38 et ressort par les ouvertures 30.The operation of this device is as follows. During a break, an arc appears between the movable contact 8 and the fixed contact 10. A quantity of hot gas is generated. It is propagated from the nozzle 12 in the sleeve 16 that it runs along its entire length until it reaches the dome 18 on which it is oriented perpendicularly so as to pass through the orifices 20. The jet of gas then strikes the rounded portions of the shell 22 making a first change of direction. The gas then travels through the annular passage 42. A portion of the gas exits directly through the orifices 30 while the remaining portion of the gas flows to the bottom 44 in which it undergoes a second change of direction. The gas then returns to the orifices 30 passing over the radial partitions 32, 34, 36, 38 and leaves through the openings 30.
