In this case, the device is placed in an electrical circuit for supplying electricity to a railway vehicle in order to protect said electrical supply circuit in the event of a short circuit.

On connait du document CN 104330733 un disjoncteur à haute tension disposé en partie sur la toiture d'un véhicule et s'étendant à travers une ouverture ménagée dans ladite toiture. Ce disjoncteur comprend une enveloppe en matériau époxy, un interrupteur à vide à l'intérieur duquel s'étendent un premier contact électrique et un deuxième contact électrique mobile par rapport au premier contact électrique, chaque contact électrique étant relié à des connecteurs présentant des potentiels élevés, typiquement des potentiels supérieurs à 5 kV. Un tel dispositif est aussi connu du document FR 2 925 755 A1 .We know from the document CN 104330733 a high voltage circuit breaker disposed in part on the roof of a vehicle and extending through an opening made in said roof.

Un tel dispositif ne donne pas cependant entière satisfaction et est notamment susceptible d'engendrer un risque d'amorçage interne d'un arc électrique.However, such a device is not entirely satisfactory and is in particular liable to give rise to a risk of internal ignition of an electric arc.

Un but de l'invention est de proposer un dispositif électrique limitant le risque de dysfonctionnement.An object of the invention is to provide an electrical device limiting the risk of malfunction.

A cet effet, l'invention a pour objet un dispositif électrique de type précité selon la revendication 1.To this end, the invention relates to an electrical device of the aforementioned type according to claim 1.

Le dispositif électrique est donc plus sûr, et sa durée de vie est en outre prolongée.The electrical device according to the invention makes it possible, through said screen, to oppose the creation and propagation of a possible electric arc outside the enclosure. The screen also makes it possible to limit the diffusion, in the direction of electrically live parts, of humidity and dust present outside the device.

L'invention a également pour objet un véhicule, notamment ferroviaire, comprenant un dispositif électrique tel que défini ci-dessus.The subject of the invention is also a vehicle, in particular a railway vehicle, comprising an electrical device as defined above.

D'autres aspects et avantages de l'invention apparaîtront à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en se référant aux dessins annexés, sur lesquels :

  • la figure 1 est une vue schématique en coupe d'un dispositif électrique selon l'invention, le dispositif comprenant une enceinte haute tension à l'intérieur de laquelle s'est formé un arc électrique, le dispositif comprenant en outre un écran disposé à l'écart d'un organe d'entrainement ;
  • la figure 2 est une vue schématique en coupe d'une partie d'un dispositif électrique analogue au dispositif de la figure 1, dans lequel l'écran est en contact avec l'organe d'entrainement ; et

Other aspects and advantages of the invention will become apparent on reading the description which follows, given solely by way of example, and made with reference to the appended drawings, in which:

Dans la suite de la description, l'expression « sensiblement égal à » définit une relation d'égalité à plus ou moins 20%, de préférence à plus ou moins 10%.In the remainder of the description, the expression “substantially equal to” defines a relation of equality at plus or minus 20%, preferably at plus or minus 10%.

On entend par « haute tension » au sens de l'invention, une tension électrique sensiblement supérieure ou égale à 5 kilovolts (5 kV).For the purposes of the invention, the term “high voltage” is understood to mean an electric voltage substantially greater than or equal to 5 kilovolts (5 kV).

Sur la figure 1, un dispositif électrique 10 est destiné à être monté au-dessus ou à l'intérieur d'un véhicule ferroviaire (non représenté), en particulier un train, un tramway, un métro ou autre. De façon classique, le véhicule ferroviaire comprend notamment un toit, un pantographe et un réseau électrique haute tension. Le dispositif électrique 10 est par exemple destiné à être monté sur le toit du véhicule ferroviaire.On the figure 1 , an electrical device 10 is intended to be mounted above or inside a railway vehicle (not shown), in particular a train, a tram, a metro or the like. Conventionally, the rail vehicle comprises in particular a roof, a pantograph and a high voltage electrical network. The electrical device 10 is for example intended to be mounted on the roof of the rail vehicle.

Le dispositif électrique 10 est par exemple un disjoncteur, un commutateur, un contacteur, ou tout autre dispositif configuré pour permettre la circulation d'un courant électrique ayant une tension supérieure ou égale à 5 kV. Le courant est notamment apte à circuler via des pièces nues sous tension.The electrical device 10 is for example a circuit breaker, a switch, a contactor, or any other device configured to allow the circulation of an electric current having a voltage greater than or equal to 5 kV. The current is in particular able to flow via bare live parts.

En référence à la figure 1, le dispositif 10 comprend une enceinte haute tension 12, un actionneur 14, un organe d'entrainement 16 et un écran 18. Le terme « écran » signifie au sens de la présente invention une paroi de séparation ou une membrane de séparation. De préférence, le dispositif électrique 10 comprend en outre un support 19.With reference to the figure 1 , the device 10 comprises a high voltage enclosure 12, an actuator 14, a drive member 16 and a screen 18. The term “screen” means within the meaning of the present invention a separation wall or a separation membrane. Preferably, the electrical device 10 further comprises a support 19.

L'enceinte haute tension 12 est configurée pour permettre la circulation d'un courant électrique ayant une tension supérieure ou égale à 5 kV.The high voltage enclosure 12 is configured to allow the flow of an electric current having a voltage greater than or equal to 5 kV.

L'enceinte 12 est susceptible de présenter différentes formes suivant la nature du dispositif électrique 10. Par exemple, l'enceinte 12 présente une forme de parallélépipède rectangle. En variante, l'enceinte 12 présente une symétrie de révolution autour d'un axe longitudinal.The enclosure 12 is likely to have different shapes depending on the nature of the electrical device 10. For example, the enclosure 12 has the shape of a rectangular parallelepiped. As a variant, the enclosure 12 has a symmetry of revolution about a longitudinal axis.

Dans l'exemple de la figure 1, l'enceinte 12 présente une forme sensiblement cylindrique s'étendant selon un axe longitudinal A.In the example of figure 1 , the enclosure 12 has a substantially cylindrical shape extending along a longitudinal axis A.

L'enceinte 12 définit une cavité 20 centrale délimitée par une paroi externe 22. L'enceinte 12 présente au moins une ouverture 24. Dans l'exemple de la figure 1, l'enceinte 12 présente une première ouverture 24 orientée vers l'actionneur 14. La première ouverture 24 est de préférence disposée à proximité de l'actionneur 14, par exemple à une distance inférieure à 5 cm de l'actionneur 14.The enclosure 12 defines a central cavity 20 delimited by an outer wall 22. The enclosure 12 has at least one opening 24. In the example of figure 1 , the enclosure 12 has a first opening 24 oriented towards the actuator 14. The first opening 24 is preferably placed near the actuator 14, for example at a distance of less than 5 cm from the actuator 14.

Avantageusement, la paroi externe 22 présente une pluralité d'ailettes 26 annulaires circonférentielles s'étendant en saillie radialement vers l'extérieur du dispositif 10. Les ailettes 26 sont sensiblement parallèles entre elles. Les ailettes 26 réduisent le risque de création et propagation d'un arc électrique à la surface de la paroi externe 22 de l'enceinte 12.Advantageously, the outer wall 22 has a plurality of circumferential annular fins 26 extending radially outwardly from the device 10. The fins 26 are substantially parallel to one another. The fins 26 reduce the risk of creating and propagating an electric arc on the surface of the outer wall 22 of the enclosure 12.

L'enceinte 12 est réalisée en un matériau isolant. Avantageusement, l'enceinte 12 est dépourvue de matériau métallique de sorte à n'assurer aucune conduction électrique. De préférence, l'enceinte 12 est réalisée en un matériau polymérique. Le matériau polymérique comprend préférentiellement au moins un polymère époxyde, aussi connu sous le nom de « polyépoxyde » ou de « polymère époxy ». En variante, l'enceinte 12 est réalisée en un matériau céramique.The enclosure 12 is made of an insulating material. Advantageously, the enclosure 12 is devoid of metallic material so as to ensure no electrical conduction. Preferably, the enclosure 12 is made of a polymeric material. The polymeric material preferably comprises at least one epoxy polymer, also known under the name of “polyepoxide” or of “epoxy polymer”. As a variant, the enclosure 12 is made of a ceramic material.

Sur la figure 1, un arc électrique 27 est représenté se propageant à l'intérieur de l'enceinte 12.On the figure 1 , an electric arc 27 is shown propagating inside the enclosure 12.

L'enceinte 12 comporte un interrupteur électrique 30, disposé dans l'enceinte 12.The enclosure 12 comprises an electrical switch 30, arranged in the enclosure 12.

L'interrupteur électrique 30 comprend un premier contact électrique 32, un deuxième contact électrique 34 et une ampoule 36 à l'intérieur de laquelle s'étendent le premier contact électrique 32 et le deuxième contact électrique 34.The electrical switch 30 comprises a first electrical contact 32, a second electrical contact 34 and a bulb 36 within which extend the first electrical contact 32 and the second electrical contact 34.

Par exemple, l'interrupteur 30 est un interrupteur à vide, l'ampoule 36 étant alors une ampoule à vide. Comme connu en soi, l'utilisation d'un interrupteur à vide 30 permet de commuter des courants et d'isoler un circuit sous une tension élevée avec des distances inter-contact faibles, le vide jouant le rôle d'isolant électrique.For example, the switch 30 is a vacuum interrupter, the bulb 36 then being a vacuum interrupter. As known per se, the use of a vacuum interrupter 30 allows to switch currents and to isolate a circuit under a high voltage with short inter-contact distances, the vacuum playing the role of electrical insulator.

Le premier contact 32 est fixe par rapport à l'ampoule 36. Le deuxième contact électrique 34 est mobile entre une position de fermeture (ou position fermée) de l'interrupteur 30 dans laquelle le deuxième contact 34 est en appui contre le premier contact 32 (comme représenté sur la figure 1) et une position d'ouverture (ou position ouverte) de l'interrupteur 30 dans laquelle le deuxième contact 34 est à l'écart du premier contact 32.The first contact 32 is fixed relative to the bulb 36. The second electrical contact 34 is movable between a closed position (or closed position) of the switch 30 in which the second contact 34 bears against the first contact 32. (as shown on figure 1 ) and an open position (or open position) of the switch 30 in which the second contact 34 is away from the first contact 32.

Les contacts électriques 32, 34 sont reliés électriquement à une borne respective de connexion électrique 38, 40, chaque borne de connexion 38, 40 étant disposée à l'extérieur de l'ampoule 36. Par exemple, le deuxième contact électrique 34 est relié à sa borne de connexion 40 respective au moyen d'une tresse 42.The electrical contacts 32, 34 are electrically connected to a respective electrical connection terminal 38, 40, each connection terminal 38, 40 being disposed outside the bulb 36. For example, the second electrical contact 34 is connected to its respective connection terminal 40 by means of a braid 42.

Comme connu en soi, les bornes de connexion 38, 40 sont aptes à être reliées électriquement entre elles en position de fermeture de l'interrupteur 30, les contacts électriques 32, 34 étant alors en appui l'un contre l'autre, et sont aptes à être isolées électriquement l'une de l'autre en position d'ouverture de l'interrupteur 30, les contacts électriques 32, 34 étant alors à l'écart l'un de l'autre. Les bornes de connexion 38, 40 sont propres à supporter des tensions électriques supérieures à 5 kV. Les bornes de connexion 38, 40 sont par exemple reliées à un pantographe ou au réseau électrique du véhicule ferroviaire.As known per se, the connection terminals 38, 40 are able to be electrically connected together in the closed position of the switch 30, the electrical contacts 32, 34 then being pressed against each other, and are capable of being electrically isolated from one another in the open position of the switch 30, the electrical contacts 32, 34 then being away from one another. The connection terminals 38, 40 are suitable for withstanding electrical voltages greater than 5 kV. The connection terminals 38, 40 are for example connected to a pantograph or to the electrical network of the railway vehicle.

L'organe d'entrainement 16 est disposé à l'extérieur de l'interrupteur 30 et s'étend selon un axe d'extension. Dans l'exemple de la figure 1, ledit axe d'extension est confondu avec l'axe longitudinal A de l'enceinte 12. L'organe d'entrainement 16 s'étend à travers l'ouverture de l'enceinte 12.The drive member 16 is arranged outside the switch 30 and extends along an axis of extension. In the example of figure 1 , said axis of extension coincides with the longitudinal axis A of the enclosure 12. The drive member 16 extends through the opening of the enclosure 12.

L'organe d'entrainement 16 présente une première extrémité 50 et une deuxième extrémité 52 opposée à la première extrémité 50 selon l'axe d'extension de l'organe d'entrainement 16. L'organe d'entrainement 16 est fixé au deuxième contact 34 mobile en sa première extrémité 50 et est fixé à l'actionneur 14 en sa deuxième extrémité 52. La fixation de l'organe d'entrainement 16 en sa deuxième extrémité 52 à l'actionneur 14 est une fixation directe, ou encore indirecte via un renvoi d'angle ou un réducteur.The drive member 16 has a first end 50 and a second end 52 opposite the first end 50 along the axis of extension of the drive member 16. The drive member 16 is fixed to the second contact 34 movable at its first end 50 and is fixed to the actuator 14 at its second end 52. The fixing of the drive member 16 at its second end 52 to the actuator 14 is a direct or even indirect fixing via an angle transmission or a reduction gear.

L'organe d'entrainement 16 relie l'interrupteur 30 à l'actionneur 14. L'organe d'entrainement 16 permet le déplacement du deuxième contact électrique 34 entre la position de fermeture et la position d'ouverture de l'interrupteur 30.The drive member 16 connects the switch 30 to the actuator 14. The drive member 16 allows the movement of the second electrical contact 34 between the closed position and the open position of the switch 30.

Dans l'exemple de la figure 1, l'organe d'entrainement 16 présente la forme d'une tige 54. La tige 54 présente une section radiale, ladite section ayant par exemple la forme d'un cercle, d'une ellipse ou d'un polygone, notamment d'un rectangle.In the example of figure 1 , the drive member 16 has the shape of a rod 54. The rod 54 has a radial section, said section having for example the shape of a circle, an ellipse or a polygon, in particular of a rectangle.

L'organe d'entrainement 16 assure une isolation électrique entre le deuxième contact électrique 34 et l'actionneur 14. L'organe d'entrainement 16 est réalisé par exemple en matériau stratifié à base de fibres de verre.The drive member 16 provides electrical insulation between the second electrical contact 34 and the actuator 14. The drive member 16 is made, for example, of laminated material based on glass fibers.

Avantageusement, et comme représenté sur la figure 1, l'organe d'entrainement 16 comporte au moins une ailette 56 s'étendant en saillie radialement par rapport à la tige 54. La ou les ailette(s) 56 limite(nt) le risque de propagation d'un arc électrique 27 respectif à la surface de l'organe d'entrainement 16.Advantageously, and as shown in figure 1 , the drive member 16 comprises at least one fin 56 projecting radially with respect to the rod 54. The fin (s) 56 limit (s) the risk of propagation of a respective electric arc 27 on the surface of the drive member 16.

L'organe d'entrainement 16 comporte au moins un organe de rappel (non représenté) agencé pour exercer sur le deuxième contact électrique 34 un effort de rappel de la position de fermeture de l'interrupteur 30 vers la position d'ouverture de l'interrupteur 30. L'organe de rappel est par exemple un ressort.The drive member 16 comprises at least one return member (not shown) arranged to exert on the second electrical contact 34 a return force from the closed position of the switch 30 to the open position of the switch. switch 30. The return member is for example a spring.

L'actionneur 14 agit à l'encontre de l'organe de rappel. L'actionneur 14 est agencé pour exercer une force opposée à la force exercée par l'organe de rappel en maintenant le deuxième contact électrique 34 dans la position fermée. Dans l'exemple de la figure 1, l'actionneur 14 est un électroaimant.The actuator 14 acts against the return member. The actuator 14 is arranged to exert a force opposite to the force exerted by the return member while maintaining the second electrical contact 34 in the closed position. In the example of figure 1 , the actuator 14 is an electromagnet.

L'actionneur 14 est disposé sur un support. Par exemple, l'actionneur 14 est disposé à l'intérieur d'un caisson 58.The actuator 14 is arranged on a support. For example, the actuator 14 is placed inside a box 58.

L'actionneur 14 est configuré pour entrainer le déplacement de l'organe d'entrainement 16 et ainsi le déplacement du deuxième contact électrique 34 entre la position ouverte et la position fermée. L'actionneur 14 commande ainsi le passage du courant à l'intérieur de l'interrupteur électrique 30.The actuator 14 is configured to cause the movement of the drive member 16 and thus the movement of the second electrical contact 34 between the open position and the closed position. The actuator 14 thus controls the passage of current inside the electrical switch 30.

L'écran 18 est disposé entre l'enceinte haute tension 12 et l'actionneur 14, de sorte que l'enceinte 12 et l'actionneur 14 sont disposés de part et d'autre dudit écran 18. L'écran 18 est préférentiellement fixé à l'enceinte 12, par exemple au moyen d'un organe de vissage et/ou pinçage (non représenté). En variante, l'écran 18 est collé à l'enceinte 12.The screen 18 is placed between the high voltage enclosure 12 and the actuator 14, so that the enclosure 12 and the actuator 14 are arranged on either side of said screen 18. The screen 18 is preferably fixed. to the enclosure 12, for example by means of a screwing and / or clamping member (not shown). As a variant, the screen 18 is glued to the enclosure 12.

Comme représenté sur la figure 1, la cavité 20 de l'enceinte 12 est en partie délimitée par l'écran 18. L'écran 18 obture partiellement la première ouverture 24 en une extrémité de l'enceinte 12 selon l'axe d'extension.As shown on figure 1 , the cavity 20 of the enclosure 12 is partly delimited by the screen 18. The screen 18 partially closes the first opening 24 at one end of the enclosure 12 along the axis of extension.

L'écran 18 présente une épaisseur E supérieure ou égale à 2 mm, l'épaisseur E de l'écran 18 étant mesurée selon l'axe d'extension de l'organe d'entrainement 16. Dans l'exemple des figures 1 et 2, l'épaisseur E de l'écran 18 est sensiblement constante.The screen 18 has a thickness E greater than or equal to 2 mm, the thickness E of the screen 18 being measured along the axis of extension of the drive member 16. In the example of figures 1 and 2 , the thickness E of the screen 18 is substantially constant.

En variante, sur la figure 3, l'écran 18 présente une épaisseur E non constante.Alternatively, on the figure 3 , the screen 18 has a non-constant thickness E.

L'écran 18 est réalisé en un matériau polymérique. De préférence, le matériau polymérique comprend au moins un élastomère, avantageusement au moins une silicone, aussi appelée polysiloxane.The screen 18 is made of a polymeric material. Preferably, the polymeric material comprises at least one elastomer, advantageously at least one silicone, also called polysiloxane.

L'écran 18 présente un évidement 62 à travers lequel s'étend l'organe d'entrainement 16. La distance D entre l'écran 18 et l'organe d'entrainement 16 est inférieure à 3 mm, de préférence inférieure à 2 mm.The screen 18 has a recess 62 through which extends the driving member 16. The distance D between the screen 18 and the driving member 16 is less than 3 mm, preferably less than 2 mm. .

Cette distance D limite le risque de création ou de propagation d'un arc électrique 27 formé dans l'enceinte 12 vers l'extérieur de ladite enceinte 12. Cette distance D limite en outre la diffusion de l'humidité présente dans l'air, depuis l'extérieur de l'enceinte 12 vers l'intérieur de l'enceinte 12. Ainsi, l'intérieur de l'enceinte 12 présente un taux d'humidité plus faible que le taux d'humidité à proximité de l'actionneur 14. L'écran 18 joue le rôle de barrière anti-humidité et anti-arc électrique.This distance D limits the risk of creation or propagation of an electric arc 27 formed in the enclosure 12 towards the outside of said enclosure 12. This distance D also limits the diffusion of humidity present in the air, from the outside of the enclosure 12 towards the inside of the enclosure 12. Thus, the inside of the enclosure 12 has a lower humidity level than the humidity level near the actuator 14 The screen 18 acts as an anti-humidity and anti-electric arc barrier.

L'organe d'entrainement 16 est mobile par rapport à l'écran 18.The drive member 16 is movable relative to the screen 18.

Comme représenté sur la figure 1, l'écran 18 est disposé à l'écart de l'organe d'entrainement 16. La distance D entre l'écran 18 et l'organe d'entrainement 16 est supérieure ou égale à 0,5 mm.As shown on figure 1 , the screen 18 is disposed away from the driving member 16. The distance D between the screen 18 and the driving member 16 is greater than or equal to 0.5 mm.

En variante, sur les figures 2 et 3, l'écran 18 est en appui contre l'organe d'entrainement 16. Dans l'exemple de la figure 3, l'arête 61 est en appui contre l'organe d'entrainement 16. Les forces de frottement entre l'écran 18 et l'organe d'entrainement 16 sont suffisamment faibles pour permettre le déplacement de l'organe d'entrainement 16 entre la position fermée et la position ouverte.As a variant, on figures 2 and 3 , the screen 18 rests against the driving member 16. In the example of figure 3 , the edge 61 bears against the driving member 16. The frictional forces between the screen 18 and the driving member 16 are low enough to allow the movement of the driving member 16 between the closed position and the open position.

En variante, l'écran 18 est fixé à l'organe d'entrainement 16, par exemple par collage. Selon cette variante, l'écran 18 est apte à se rompre en cas de pression supérieure à 0,2 MPa (2 bars).As a variant, the screen 18 is fixed to the drive member 16, for example by gluing. According to this variant, the screen 18 is capable of breaking in the event of a pressure greater than 0.2 MPa (2 bars).

Avantageusement, l'écran 18 est flexible. Par « flexible », on entend que l'écran 18 est apte à se déformer sous l'effet d'une pression supérieure à 0,2 MPa (2 bars), dite pression critique Pc.Advantageously, the screen 18 is flexible. The term “flexible” is understood to mean that the screen 18 is capable of deforming under the effect of a pressure greater than 0.2 MPa (2 bars), called the critical pressure Pc.

L'écran 18 est apte à se déformer entre une configuration de repos, représentée en traits pleins sur la figure 1, et une configuration déformée, représentée en traits pointillés sur la figure 1.The screen 18 is able to deform between a rest configuration, shown in solid lines on the figure 1 , and a distorted configuration, shown in dotted lines on the figure 1 .

En configuration de repos, l'écran 18 s'étend sensiblement selon un plan normal à l'axe d'extension de l'organe d'entrainement 16 et l'évidement 62 présente une aire minimale, appelée Arepos.In the rest configuration, the screen 18 extends substantially along a plane normal to the axis of extension of the drive member 16 and the recess 62 has a minimum area, called A rest .

En configuration déformée, l'écran 18 présente une surface courbe, et l'évidement 62 présente une aire supérieure à l'aire minimale Arepos.In the deformed configuration, the screen 18 has a curved surface, and the recess 62 has an area greater than the minimum area A at rest .

En cas de surpression au sein de l'enceinte 12, due par exemple à un arc électrique 27 (aussi appelé «flashover» en anglais), l'écran 18 est apte à se déformer, limitant le risque de dégradation du dispositif électrique 10, pouvant aller jusqu'à la perforation de l'enceinte 12.In the event of an overpressure within the enclosure 12, due for example to an electric arc 27 (also called “ flashover” in English), the screen 18 is able to deform, limiting the risk of degradation of the electrical device 10, up to perforation of the enclosure 12.

On comprend qu'il est possible de choisir la nature et/ou l'épaisseur E de l'écran 18 en fonction du dispositif électrique 10, des tensions mises en jeu ou de la pression susceptible d'être supportée par l'enceinte 12.It will be understood that it is possible to choose the nature and / or the thickness E of the screen 18 as a function of the electrical device 10, of the voltages involved or of the pressure capable of being supported by the enclosure 12.

Dans l'exemple de la figure 1, l'enceinte 12 est disposée sur le support 19 et s'étend selon une direction sensiblement perpendiculaire au plan dudit support 19. L'écran 18 est disposé entre l'enceinte 12 et le support 19.In the example of figure 1 , the enclosure 12 is arranged on the support 19 and extends in a direction substantially perpendicular to the plane of said support 19. The screen 18 is arranged between the enclosure 12 and the support 19.

Par exemple, le support 19 est formé par au moins une partie du toit du véhicule ferroviaire. En variante, le support 19 est formé d'une plaque fixée à au moins une partie du toit du véhicule ferroviaire.For example, the support 19 is formed by at least part of the roof of the rail vehicle. As a variant, the support 19 is formed of a plate fixed to at least part of the roof of the rail vehicle.

Le support 19 présente une ouverture 72 à travers laquelle s'étend l'organe d'entrainement 16, de sorte que l'interrupteur 30 et l'actionneur 14 sont disposés de part et d'autre du support 19.The support 19 has an opening 72 through which extends the drive member 16, so that the switch 30 and the actuator 14 are arranged on either side of the support 19.

Le fonctionnement du dispositif électrique 10 selon l'invention va être à présent décrit.The operation of the electrical device 10 according to the invention will now be described.

Lors de l'utilisation du dispositif électrique 10, un courant électrique à haute tension circule au travers des pièces conductrices de l'enceinte 12. L'écran 18 est alors en configuration de repos.When using the electrical device 10, a high voltage electric current flows through the conductive parts of the enclosure 12. The screen 18 is then in the idle configuration.

Lorsqu'un arc électrique 27 se forme à l'intérieur de l'enceinte 12, l'écran 18 fait, au moins temporairement, obstacle à la propagation dudit arc électrique 27 en dehors de l'enceinte 12.When an electric arc 27 forms inside the enclosure 12, the screen 18 forms, at least temporarily, an obstacle to the propagation of said electric arc 27 outside the enclosure 12.

L'arc électrique 27 entraine une augmentation de la pression à l'intérieur de l'enceinte 12. Lorsque la pression est inférieure à la pression critique Pc, l'écran 18 ne se déforme pas et reste en configuration de repos.The electric arc 27 causes an increase in the pressure inside the enclosure 12. When the pressure is less than the critical pressure Pc, the screen 18 does not deform and remains in the rest configuration.

Lorsque la pression à l'intérieur de l'enceinte 12 est supérieure ou égale à la pression critique Pc, l'écran 18 se déforme jusqu'à une configuration déformée représentée en traits pointillés sur la figure 1. Cela permet de réduire la pression à l'intérieur de l'enceinte 12 et de la répartir dans le caisson 58.When the pressure inside the enclosure 12 is greater than or equal to the critical pressure Pc, the screen 18 is deformed to a deformed configuration shown in dotted lines on the diagram. figure 1 . This makes it possible to reduce the pressure inside the enclosure 12 and to distribute it in the box 58.

L'écran 18 permet d'une part de gêner, voire d'empêcher, la création d'un éventuel arc électrique 27 vers l'extérieur de l'enceinte 12 et, d'autre part, de limiter la diffusion de l'humidité présente en dehors du dispositif 10 vers l'interrupteur électrique 30.The screen 18 makes it possible on the one hand to hinder, or even prevent, the creation of a possible electric arc 27 towards the outside of the enclosure 12 and, on the other hand, to limit the diffusion of humidity. present outside the device 10 to the electric switch 30.

De plus, dans le cas où l'arc électrique 27 est suffisamment important et risque d'endommager le dispositif 10, ou même d'entrainer la dégradation de l'enceinte 12, l'écran 18 se déforme, empêchant ainsi une surpression trop grande à l'intérieur du dispositif 10. Le bon fonctionnement du dispositif électrique 10 est ainsi renforcé.In addition, in the case where the electric arc 27 is sufficiently strong and risks damaging the device 10, or even causing the degradation of the enclosure 12, the screen 18 is deformed, thus preventing too great an overpressure. inside the device 10. The correct operation of the electrical device 10 is thus reinforced.

On comprend alors que le dispositif électrique 10 selon l'invention est plus sûr et présente une durée de vie plus importante que le dispositif de l'état de la technique.It will then be understood that the electrical device 10 according to the invention is safer and has a longer lifespan than the device of the state of the art.
