DOMAINE TECHNIQUE ET ART ANTÉRIEURTECHNICAL FIELD AND PRIOR ART

L'invention s'applique particulièrement à un sectionneur de terre, dit sectionneur très haute vitesse, ce type de sectionneur présentant un temps de commutation très faible et étant capable de mettre à la terre des conducteurs traversés par le courant.The invention is particularly applicable to an earthing switch, said disconnector very high speed, this type of disconnector having a very short switching time and being able to ground conductors crossed by the current.
Les sectionneurs de terre comportent généralement une enveloppe fermée de manière étanche et remplie d'un gaz diélectrique, au moins un ensemble logé dans l'enveloppe comprenant un contact de terre fixe, un contact de phase et un élément de commutation destiné à connecter électriquement le contact de terre et le contact de phase, pour mettre à la terre le contact de phase.The earthing switches generally comprise a casing sealed and filled with a dielectric gas, at least one assembly housed in the casing comprising a fixed earth contact, a phase contact and a switching element for electrically connecting the earth contact and phase contact, to ground the phase contact.
Un tel sectionneur est, par exemple connu du document JP 56-116810, dans lequel l'élément de commutation est mobile en translation selon un axe reliant le contact de terre fixe et le contact de phase. Le contact de terre fixe est fixé sur une plaque obturant une ouverture prévue dans une paroi cylindrique de l'enveloppe du sectionneur. L'élément de commutation est, quant à lui, actionné par un dispositif d' actionnement fixé sur la face intérieure de l'enveloppe.Such a disconnector is, for example known from JP 56-116810, wherein the switching element is movable in translation along an axis connecting the fixed earth contact and the phase contact. The fixed earth contact is fixed on a plate closing an opening provided in a cylindrical wall of the disconnector envelope. The switching element is, in turn, actuated by an actuating device attached to the inner face of the casing.
Ce sectionneur présente l'inconvénient d'être de fabrication longue puisque le montage du contact de terre fixe et de l'élément de commutation s'effectue en deux étapes. De plus la fixation sur la paroi interne de l'élément de commutation est complexe.This disconnector has the disadvantage of being long manufacturing since the mounting of the fixed earth contact and the switching element is carried out in two steps. In addition, the fixing on the inner wall of the switching element is complex.
Du document WO 2005/018066, est connu un autre type de sectionneur, comportant un contact de terre fixe, un contact de phase et un élément de commutation, le contact de terre étant décalé par rapport à la direction axiale de déplacement de l'élément de commutation. Ce sectionneur apparaît comme relativement encombrant.Document WO 2005/018066 discloses another type of disconnector comprising a fixed earth contact, a phase contact and a switching element, the earth contact being offset with respect to the axial direction of movement of the element. of commutation. This disconnector appears to be relatively bulky.
On connaît également du document EP 1 507 274, un sectionneur de terre, dans lequel le contact de terre fixe, l'élément de commutation et son dispositif d' actionnement sont assemblés sur une même plaque, qui est elle-même fixée sur l'enveloppe du sectionneur .Also known from EP 1 507 274, an earthing switch, in which the fixed earth contact, the switching element and its actuating device are assembled on the same plate, which is itself fixed on the disconnector envelope.
L'élément de commutation est apte à se déplacer en rotation autour d'un axe sensiblement parallèle à l'axe reliant le contact de terre fixe et le contact de phase et se déplace dans un plan perpendiculaire à cet axe. L'élément de commutation est de forme relativement complexe. II est également connu du document USThe switching element is able to move in rotation about an axis substantially parallel to the axis connecting the fixed earth contact and the phase contact and moves in a plane perpendicular to this axis. The switching element is relatively complex in shape. It is also known from the US document

Un contact mobile est porté par un mécanisme d' actionnement , le contact mobile se déplace perpendiculairement à la plaque. La distance entre la plaque de montage et le deuxième contact mobile est très importante, le sectionneur est donc très encombrant.2004/0042158 an earthing switch in an envelope waterproof housing comprising an envelope and a plate on which is mounted a ground switch, and two electrodes each connected to a conductor.

C'est par conséquent un but de la présente invention d'offrir un sectionneur de terre de réalisation simple et de maintenance facilitée.It is therefore an object of the present invention to provide an earthing switch of simple construction and easy maintenance.

EXPOSÉ DÉTAILLÉ DE MODES DE RÉALISATION PARTICULIERSDETAILED PRESENTATION OF PARTICULAR EMBODIMENTS
La présente invention s'applique à la fois aux sectionneurs de terre monophasés et aux sectionneurs de terre triphasés.The present invention applies to both single-phase earthing switches and three-phase earthing switches.
Nous décrirons par la suite un sectionneur de terre triphasé.We will describe a three-phase earthing switch.
Sur la figure 1, on peut voir un sectionneur de terre ou de mise à la terre comportant un boîtier 2 comprenant une ouverture 4 permettant d'accéder à l'intérieur du boîtier 2.In FIG. 1, an earthing or earthing switch having a housing 2 comprising an opening 4 allowing access to the inside of the housing 2 can be seen.
Dans l'exemple représenté, l'ouverture est circulaire mais on peut prévoir une ouverture polygonale, par exemple de forme carrée.In the example shown, the opening is circular but it can provide a polygonal opening, for example of square shape.
Le sectionneur comporte également un couvercle 6 formé par une plaque, destiné à obturer de manière étanche l'ouverture 4, afin de délimiter avec le boîtier 2 un volume étanche destiné à contenir un gaz diélectrique. Par la suite, cette plaque 6 sera appelée plaque de montage.The disconnector also comprises a cover 6 formed by a plate, intended to seal the opening 4, in order to define with the housing 2 a sealed volume for containing a dielectric gas. Subsequently, this plate 6 will be called mounting plate.
Le boîtier 2 et la plaque 6 peuvent être réalisés par exemple en aluminium.The housing 2 and the plate 6 can be made for example of aluminum.
Le boîtier 2 comporte trois barres conductrices 8 (une seule est visible sur la figure 1) disposées sensiblement parallèlement et maintenues dans le boîtier 2 par l'intermédiaire d'une plaque 10 en matériau isolant. Les barres 8 sont, par exemple, disposées dans un même plan ou en triangle. Le sectionneur de terre comporte également des moyens pour mettre à la terre chacune des barres conductrices 8. Ces moyens comprennent, pour chaque barre conductrice 8, un contact de terre 12, un contact de phase 14 et un moyen de connexion électrique mobile 16 entre le contact de terre 12 et le contact de phase 14.The housing 2 comprises three conductive bars 8 (only one is visible in Figure 1) disposed substantially parallel and held in the housing 2 through a plate 10 of insulating material. The bars 8 are, for example, arranged in the same plane or in a triangle. The earthing switch also comprises means for grounding each of the busbars 8. These means comprise, for each busbar 8, an earth contact 12, a phase contact 14 and a movable electrical connection means 16 between the earth contact 12 and phase contact 14.
Selon la présente invention, le contact de terre 12, le contact de phase 14 et le moyen de connexion mobile 16 sont montés sur une face intérieure 18 de la plaque de montage 6, permettant ainsi un pré assemblage de l'ensemble de mise à la terre avant la fermeture du boîtier.According to the present invention, the earth contact 12, the phase contact 14 and the mobile connection means 16 are mounted on an inner face 18 of the mounting plate 6, thus allowing a pre-assembly of the setting assembly. ground before closing the case.
Dans le cas d'un sectionneur de terre triphasé, celui-ci comporte, dans l'exemple représenté, les trois mêmes moyens de mise à la terre, nous décrirons les moyens de mise à la terre associés à une barre conductrice.In the case of a three-phase earthing switch, it comprises, in the example shown, the same three grounding means, we will describe the grounding means associated with a conductive bar.
Le contact de terre fixe 12 comporte une tige 20 montée par une première extrémité 22 dans passage 24 pratiqué dans la plaque de montage 6. La tige 20 est, dans l'exemple représenté, sensiblement perpendiculaire à la plaque de montage 6.The fixed earth contact 12 comprises a rod 20 mounted by a first end 22 in passage 24 formed in the mounting plate 6. The rod 20 is, in the example shown, substantially perpendicular to the mounting plate 6.
Cette tige 20 est, par exemple, rendue solidaire de la plaque de montage 6 au moyen d'un ensemble de vis, directement vissé dans des alésages prévus dans une face extérieure 26 de la plaque de montage 6.This rod 20 is, for example, made integral with the mounting plate 6 by means of a set of screws directly screwed into bores provided in an outer face 26 of the mounting plate 6.
Dans l'exemple représenté en détail sur la figure 3, une plaquette 28 est fixée à l'extrémité 22 de la tige 20 par une vis 30, et ladite plaquette 28 est solidarisée à la plaque de montage 6 par des visIn the example shown in detail in FIG. 3, a plate 28 is fixed to the end 22 of the rod 20 by a screw 30, and said plate 28 is secured to the mounting plate 6 by screws
110. La plaquette 28, en forme de disque, est connectée à la terre par une liaison 34. Cette liaison 34 en forme de plaquette rectangulaire est fixée par une extrémité à la plaquette 28 au moyen d'une vis 32, et par une deuxième extrémité à la plaque 6 au moyen d'une vis 113. Il est prévu entre le la plaque 6 et la plaquette 34 une entretoise conductrice électriquement110. The disc-shaped plate 28 is connected to the earth by a connection 34. This connection 34 in the form of a rectangular plate is fixed at one end to the plate 28 by means of a screw 32, and by a second end to the plate 6 by means of a screw 113. There is provided between the plate 6 and the plate 34 an electrically conductive spacer
(non visible). D'autres moyens de fixation entre les éléments 28,34, et 6 sont envisageables.(non visible). Other fixing means between the elements 28, 34, and 6 are conceivable.
De manière avantageuse, un manchon 23 en matériau isolant est disposé entre l'ensemble tige 20 - plaquette 28 et la paroi du passage 24 de manière à isoler le contact de terre 12 de la plaque de montage 6. Un manchon isolant est également prévu entre la vis 111 et la plaque 6 (figure 3) .Advantageously, a sleeve 23 of insulating material is disposed between the assembly 20-wafer rod 28 and the wall of the passage 24 so as to isolate the earth contact 12 of the mounting plate 6. An insulating sleeve is also provided between the screw 111 and the plate 6 (Figure 3).
Cette configuration permet avantageusement de mesurer le courant dans le contact de terre 12.This configuration advantageously makes it possible to measure the current in the earth contact 12.
A l'intérieur du boîtier 2, la tige de terre 20 comporte un passage 38 traversant dont l'axe Y est sensiblement orthogonal à l'axe principal X de la tige 20, permettant le passage d'un élément de connexion formant le moyen de connexion mobile 16. L'élément de connexion a la forme d'une tige dans l'exemple représenté.Inside the housing 2, the earth rod 20 comprises a through passage 38 whose Y axis is substantially orthogonal to the main axis X of the rod 20, allowing the passage of a connecting element forming the means of mobile connection 16. The connection element has the shape of a rod in the example shown.
La tige 16 est mobile selon l'axe Y entre une première position d' isolation du contact de terre 12 et du contact de phase 14 (représentée en trait plein sur la figure 2) et une deuxième position de connexion électrique entre le contact de terre 12 et le contact de phase 14 (représentée en pointillés sur la figure 2) .The rod 16 is movable along the Y axis between a first isolation position of the earth contact 12 and the phase contact 14 (shown in solid lines in FIG. 2) and a second position of electrical connection between the earth contact 12 and the phase contact 14 (shown in dashed lines in FIG. 2).
La tige 16 est réalisée, par exemple en cuivre argenté, et son extrémité 50 destinée à venir en contact avec le contact de phase, est réalisée en un matériau résistant aux arcs électriques, tel qu'un alliage de cuivre et de tungstène.The rod 16 is made of, for example silver-plated copper, and its end 50 intended to come into contact with the phase contact, is made of a material resistant to electric arcs, such as a copper alloy and tungsten.
Dans la première position, la tige 16 est maintenue dans le passage 38. De manière avantageuse, comme on peut le voir sur la figure 4, un élément de contact 42 en forme de tulipe est monté dans le passage 38. La forme particulière de l'élément de connexion 42 permet de compenser les défauts d'alignement et ainsi d'assurer un contact électrique permanent entre la tige 16 du moyen de connexion mobile et le contact de terre 12. L'élément 42 est réalisé en un matériau élastiquement déformable et électriquement conducteur, par exemple en un alliage de cuivre et de chrome. Un manchon de guidage 46 est disposé, avantageusement à l'intérieur de l'élément 42 en forme de tulipe pour améliorer le guidage axial de la tige 16. Le manchon 46 a un diamètre intérieur sensiblement égal au diamètre de la tige 16 et un diamètre extérieur inférieur au diamètre au repos de l'élément 42 en forme de tulipe Ce manchon 46 est également réalisé en un matériau isolant, offrant des propriétés de glissement, et plus souple que celui composant la tige 16, par exemple en un matériau thermoplastique, par exemple du polyéthylènethéraphtalate . Le manchon de guidage 46 est de longueur suffisante pour éviter le coincement de la tige 16. Le manchon de guidage 46, par exemple une longueur égale à 2 à 3 fois le diamètre de la tige 16.In the first position, the rod 16 is held in the passage 38. Advantageously, as can be seen in FIG. 4, a tulip-shaped contact element 42 is mounted in the passage 38. The particular shape of the connection element 42 makes it possible to compensate for misalignments and thus to ensure permanent electrical contact between the rod 16 of the mobile connection means and the earth contact 12. The element 42 is made of an elastically deformable material and electrically conductive, for example an alloy of copper and chromium. A guide sleeve 46 is advantageously disposed inside the tulip-shaped element 42 to improve the axial guidance of the rod 16. The sleeve 46 has an internal diameter substantially equal to the diameter of the rod 16 and a diameter outside the diameter at rest of the element 42 in the form of a tulip This sleeve 46 is also made of an insulating material, offering sliding properties, and more flexible than that comprising the rod 16, for example a thermoplastic material, by example of polyethylene terephthalate. The guiding sleeve 46 is of sufficient length to prevent jamming of the rod 16. The guide sleeve 46, for example a length equal to 2 to 3 times the diameter of the rod 16.
Sur la figure 4, on peut voir un exemple de montage de du contact 42 en forme de tulipe et du manchon 46 sur le contact de terre 12. Le contact de terre 12 comporte une partie taraudée 121 dans laquelle vient se visser le contact 42 au moyen d'une partie filetée extérieure 421. Le manchon 46 comporte une saillie annulaire 461 pincée entre un talon annulaire 442 d'une bague 44 et une extrémité inférieure 422 du contact 42, la bague 44 comportant un taraudage 441 coopérant avec le filetage 421 du contact 42.FIG. 4 shows an example of mounting of the tulip-shaped contact 42 and the sleeve 46 on the earth contact 12. The earth contact 12 comprises a threaded portion 121 in which the contact 42 is screwed in. The sleeve 46 has an annular projection 461 pinched between an annular bead 442 of a ring 44 and a lower end 422 of the contact 42, the ring 44 having a tapping 441 cooperating with the thread 421 of the contact 42.
Dans l'exemple représenté, le contact de terre 16 est en permanence en contact avec la tige 16. En variante, on pourrait prévoir une tige 16 en retrait du contact de terre et qui viendrait uniquement en contact avec le contact de terre 12 dans le cas d'une mise à la terre.In the example shown, the earth contact 16 is permanently in contact with the rod 16. In a variant, it is possible to provide a rod 16 set back from the earth contact and which would only come into contact with the earth contact 12 in the case of an earthing.
Il serait envisageable de monter la tige 16 coulissante dans le contact de phase 14 et de déplacer la tige 16 en direction du contact de terre.It would be possible to mount the sliding rod 16 in the phase contact 14 and move the rod 16 towards the earth contact.
Le contact de phase 14 est disposé à une distance d déterminée du contact de terre 12 et est aligné avec celui-ci et avec la tige 16 selon l'axe Y. Le contact de phase 14 comporte un corps 47 muni d'une cavité 48 pour recevoir une première extrémité 50 de la tige 16. De manière avantageuse, la cavité 48 est munie d'un élément de contact 52 en forme de tulipe, réalisé en un matériau conducteur, identique au non à celui formant l'élément 42. L'élément 52 comporte avantageusement une couronne en un matériau résistant aux arcs électriques. L'élément 52 est avantageusement fixé dans la cavité 48, par exemple par vissage dans le fond de la cavité. Une fixation par encliquetage peut également être envisagée. Le contact de phase 14 est solidaire de la plaque de montage 6. Dans l'exemple représenté, le contact de phase 14 est monté sur une plaque support 54, fixée par une première extrémité 56 à une deuxième extrémité 36 de la tige 20 et par une deuxième extrémité 58 à au moins un axe 60 solidaire de la plaque de montage 6.The phase contact 14 is arranged at a determined distance d from the earth contact 12 and is aligned therewith and with the rod 16 along the Y axis. The phase contact 14 comprises a body 47 provided with a cavity 48 to receive a first end 50 of the rod 16. Advantageously, the cavity 48 is provided with a contact member 52 in the form of a tulip, made of a conductive material, identical to that not forming the element 42. L element 52 advantageously comprises a crown made of a material arc-resistant. The element 52 is advantageously fixed in the cavity 48, for example by screwing into the bottom of the cavity. Snap fastening may also be considered. The phase contact 14 is integral with the mounting plate 6. In the example shown, the phase contact 14 is mounted on a support plate 54, fixed by a first end 56 to a second end 36 of the rod 20 and by a second end 58 to at least one axis 60 secured to the mounting plate 6.
Sur la figure 2, on peut voir la plaque support 54 en pointillé, sur laquelle les trois contacts de phase 14 sont montés. Dans l'exemple représenté, la plaque support 54 est fixée sur la plaque de montage 6 par deux axes 60 et les trois tiges 20. Comme le montre la figure 2, deux axes 60' supplémentaires sont prévus. Ceux-ci sont disposés entre les tiges de terre 20 et relient la plaque support 54 à la plaque de montage 6, ce qui permet de réduire les sollicitations mécaniques sur les tiges de terre 20.In Figure 2, we can see the support plate 54 in dotted line, on which the three phase contacts 14 are mounted. In the example shown, the support plate 54 is fixed on the mounting plate 6 by two axes 60 and the three rods 20. As shown in Figure 2, two additional axes 60 'are provided. These are arranged between the earth rods 20 and connect the support plate 54 to the mounting plate 6, which makes it possible to reduce the mechanical stresses on the earth rods 20.
La plaque support 54 est réalisée en un matériau isolant pour tenir les tensions de service et d'essai de la barre conductrice 8.The support plate 54 is made of an insulating material to hold the service and test voltages of the conductive bar 8.
Le contact de phase 14 est destiné à être connecté à une tige conductrice 8 correspondante, lors du montage de la plaque de montage 6 sur le boîtier 2.The phase contact 14 is intended to be connected to a corresponding conducting rod 8, during mounting of the mounting plate 6 on the housing 2.
Il est prévu, de manière avantageuse, une connexion automatique du contact de phase 14 et de la tige conductrice 8. Pour cela le contact de phase 14 peut comporter un connecteur tel que celui décrit dans le document FR 2 811 147, ayant une forme de cylindre muni de lamelles recouvert d'un matériau conducteur.Advantageously, an automatic connection of the phase contact 14 and the conducting rod 8 is provided. For this, the phase contact 14 may comprise a connector such as that described in document FR 2 811 147, having a cylinder shape provided with lamellae covered with a conductive material.
Le contact de phase 14 est disposé sur la plaque de montage 6, de manière à ce que lors du montage il soit aligné avec la partie de connexion de la barre conductrice 8.The phase contact 14 is arranged on the mounting plate 6, so that during assembly it is aligned with the connection portion of the conductive bar 8.
Ainsi, lors de la fixation de la plaque de montage 6 sur le boîtier 2, le connecteur pénètre automatiquement dans l'élément de connexion 101 fixé à la barre conductrice 8, évitant toute intervention supplémentaire pour réaliser cette connexion et donc toute ouverture supplémentaire pour atteindre l'intérieur du boîtier. Le sectionneur comporte également un dispositif d' actionnement 62 du moyen de connexion mobile 16, avantageusement monté sur la plaque de montage 6. En variante, ce dispositif d' actionnement pourrait également être disposé sur le boîtier 2. Le sectionneur comporte un arbre 64 apte à être entraîné par un arbre d'entraînement (non visible) du dispositif d' actionnement 62. L'arbre entraîné 62 est monté libre en rotation dans un passage 66 traversant la plaque de montage 6, sensiblement perpendiculairement à celle-ci au moyen de paliers 68. Le déplacement en rotation de l'arbre 64 s'effectue de manière étanche, pour cela des moyens d'étanchéité 70, par exemple des joints toriques sont montés dans des gorges pratiquées dans la périphérie de l'arbre 64. Des gorges prévues dans la paroi du passageThus, when fixing the mounting plate 6 on the housing 2, the connector automatically enters the connection element 101 fixed to the conductive bar 8, avoiding any additional intervention to make this connection and therefore any additional opening to reach the inside of the case. The disconnector also comprises an actuating device 62 of the mobile connection means 16, advantageously mounted on the mounting plate 6. Alternatively, this actuating device could also be arranged on the housing 2. The disconnector comprises a suitable shaft 64 to be driven by a drive shaft (not visible) of the actuating device 62. The driven shaft 62 is rotatably mounted in a passage 66 passing through the mounting plate 6, substantially perpendicular thereto by means of Bearings 68. The rotational movement of the shaft 64 is effected in a sealed manner, for this sealing means 70, for example O-rings are mounted in grooves formed in the periphery of the shaft 64. Grooves provided in the wall of the passage
66 sont également envisageables. L'arbre 64 est muni d'une butée 72 du côté intérieur et du côté extérieur de la plaque de montage pour maintenir axialement cet arbre 64.66 are also conceivable. The shaft 64 is provided with a stop 72 on the inside and the outside of the mounting plate for axially holding the shaft 64.
L'arbre 64 est raccordé par une première extrémité (non visible) à un moyen d'activation monté sur la face extérieure de la plaque de montage 6. Le moyen d'activation peut être de type électrique.The shaft 64 is connected by a first end (not visible) to an activation means mounted on the outer face of the mounting plate 6. The activation means may be of the electric type.
Le sectionneur comporte également un mécanisme de bielle 74 (figure 2) raccordé à une deuxième extrémité 78 de l'arbre 64 et à une extrémité 79 de la tige 16, opposée à l'extrémité destinée à venir pénétrer dans la cavité 48 du contact de phase 14.The disconnector also comprises a connecting rod mechanism 74 (FIG. 2) connected to a second end 78 of the shaft 64 and at one end 79 of the rod 16, opposite the end intended to penetrate into the cavity 48 of the contact of phase 14.
Le mécanisme de bielle 74 comporte un premier levier 80 lié par une première extrémité en rotation à l'arbre 64 et un deuxième levier 82 monté libre en rotation sur une deuxième extrémité du premier levier 80 et sur l'extrémité 79 de la tige 16.The connecting rod mechanism 74 comprises a first lever 80 connected by a first end in rotation to the shaft 64 and a second lever 82 mounted free to rotate on a second end of the first lever 80 and on the end 79 of the rod 16.
La tige 16 est isolée électriquement du deuxième levier 82, par exemple au moyen de manchons 81a, 81b en matériau électriquement isolant.The rod 16 is electrically insulated from the second lever 82, for example by means of sleeves 81a, 81b of electrically insulating material.
Ainsi le mouvement de rotation de l'arbre 64 est transformé en mouvement de translation de la tige 16. Dans l'exemple représenté en figure 2, les trois extrémités 79 des tiges 16 sont raccordées à une barre transversale unique 84, sur laquelle le deuxième levier 82 est articulé. Ainsi, l' actionnement de l'arbre 64 permet de déplacer simultanément les trois tiges 16. On pourrait cependant prévoir un mécanisme d' actionnement séparé pour chaque tige 16, c'est-à-dire pour chaque ensemble de mise à la terre.Thus the rotational movement of the shaft 64 is transformed into translational movement of the rod 16. In the example shown in Figure 2, the three ends 79 of the rods 16 are connected to a single transverse bar 84, on which the second lever 82 is articulated. Thus, the actuation of the shaft 64 makes it possible to simultaneously move the three rods 16. However, it would be possible to provide a separate actuating mechanism for each rod 16, that is to say for each set of grounding.
Comme décrit précédemment, on pourrait également prévoir de fixer le dispositif d' actionnement 62 sur le boîtier 2 ; celui-ci pourrait par exemple être formé par un poussoir disposé axialement en arrière de la tige 16 par rapport aux contacts 12 et 14. La plaque de montage 6 est destinée à être fixée sur le boîtier 2 pour obturer l'ouverture 4 de manière étanche. L'ouverture 4 est bordée par une portée annulaire 86 formant un appui pour la bordure extérieure de la plaque de montage 6. Un moyen d'étanchéité 87 est interposé entre la portée 86 et la bordure extérieure de la plaque de montage 6.As previously described, it would also be possible to fix the actuating device 62 on the housing 2; this could for example be formed by a pusher disposed axially behind the rod 16 relative to the contacts 12 and 14. The mounting plate 6 is intended to be fixed on the housing 2 to seal the opening 4 sealingly . The opening 4 is bordered by an annular bearing surface 86 forming a support for the outer edge of the mounting plate 6. A sealing means 87 is interposed between the bearing surface 86 and the outer edge of the mounting plate 6.
Comme on peut l'observer, le mécanisme de bielle 74, la tige 16 et les contacts de terre 12 et de phase 14 sont sensiblement dans un même plan parallèle à la plaque de montage 6. Ceci permet d'avoir une configuration relativement plane de la partie de mise à la terre du sectionneur.As can be seen, the link mechanism 74, the rod 16 and the earth contacts 12 and phase 14 are substantially in the same plane parallel to the mounting plate 6. This allows for a relatively flat configuration of the earthing part of the disconnector.
La distance D entre la plaque de montage 6 et le plan de déplacement de l'ensemble de mise à la terre peut être choisie relativement faible, en tenant compte cependant d'une distance minimale d'isolation entre le contact de phase 14 et la plaque de montage 6.The distance D between the mounting plate 6 and the plane of movement of the grounding assembly can be chosen relatively small, taking into account, however, a minimum isolation distance between the phase contact 14 and the plate mounting 6.
A titre d'exemple, on peut donner des dimensions de l'ensemble selon la présente invention pour un sectionneur de terre dont la tension de tenue est de 275kv, rempli avec un gaz diélectrique de type SF6 sous pression nominale de 6,3 bars :By way of example, dimensions of the assembly according to the present invention can be given for an earthing switch whose holding voltage is 275kv, filled with a SF6 type dielectric gas at a nominal pressure of 6.3 bars:
La distance D entre l'axe Y et la face 18 est de 97 mm, la distance d entre une extrémité libre 90 du contact de phase 14 en regard de la face intérieure de plaque de montage 18 le et cette face 18 est de 55 mm.The distance D between the Y axis and the face 18 is 97 mm, the distance d between a free end 90 of the phase contact 14 opposite the inside face of the mounting plate 18 and this face 18 is 55 mm. .
Un second exemple peut être donné pour une tension de tenue de 375 kV ; dans ce cas, la distance D entre l'axe Y et la face 18 serait de 117 mm, la distance d entre une extrémité libre 90 du contact de phase 14 en regard de la face intérieure de plaque de montage 18 le et cette face 18 est de 65 mm.A second example can be given for a withstand voltage of 375 kV; in this case, the distance D between the Y axis and the face 18 would be 117 mm, the distance d between a free end 90 of the phase contact 14 facing the inside of the mounting plate 18 and the face 18 is 65 mm.
Ces dimensions, ainsi que la longueur de la connexion entre 101 et 54 dépendent des paramètres ci- dessus, dans une moindre mesure de la forme et de la surface des électrodes.These dimensions, as well as the length of the connection between 101 and 54 depend on the above parameters, to a lesser extent the shape and surface of the electrodes.
La distance D correspond donc à l'épaisseur du mécanisme de mise à la terre dans la chambre. Celle- ci apparaît donc comme relativement faible par rapport à celle du mécanisme décrit dans le documentThe distance D therefore corresponds to the thickness of the grounding mechanism in the chamber. This appears to be relatively weak compared to the mechanism described in the document
US2004/0042158.US2004 / 0042158.
La présente invention permet de réduire le nombre d' étanchéités à réaliser, et ainsi de diminuer les risques de fuite de gaz diélectrique.The present invention makes it possible to reduce the number of seals to be produced, and thus to reduce the risk of leakage of dielectric gas.
De plus, dans le cas d'une maintenance, il suffit de retirer la plaque de montage 6, sans avoir à démonter d'autres pièces du sectionneur.In addition, in the case of maintenance, simply remove the mounting plate 6, without having to disassemble other parts of the disconnector.
En outre, le nombre d'éléments est réduit ce qui permet de diminuer le coût de revient d'un sectionneur . La présente invention permet également une grande liberté pour le montage et le positionnement du sectionneur de terre, et la configuration de l'appareillage électrique complet. Nous allons maintenant expliquer le fonctionnement de ce sectionneur selon la présente invention .In addition, the number of elements is reduced which allows to reduce the cost of a disconnector. The present invention also allows great freedom for the mounting and positioning of the earthing switch, and the configuration of the complete electrical equipment. We will now explain the operation of this disconnector according to the present invention.
Pour mettre la barre conductrice 8 à la terre, l'arbre 64 est mis en rotation par le moyen d'entraînement 62 disposé à l'extérieur du boîtier 2 autour de son axe, provoquant un coulissement du moyen de connexion 16 en direction du contact de phase 14. L'extrémité de la tige 16 pénètre alors dans l'élément de contact 52. La tige 16 assure alors la connexion électrique entre le contact de terre 12 et le contact de phase 14 (figure 2, en pointillé), et la mise à la terre de la barre conductrice 8 connectée au contact de phase 14.To ground the busbar 8, the shaft 64 is rotated by the drive means 62 disposed outside the housing 2 about its axis, causing the connection means 16 to slide towards the contact phase 14. The end of the rod 16 then enters the contact element 52. The rod 16 then provides the electrical connection between the earth contact 12 and the phase contact 14 (Figure 2, dotted), and the grounding of the conductive bar 8 connected to the phase contact 14.
Nous allons également décrire le procédé de fabrication d'un tel sectionneur de terre.We will also describe the method of manufacturing such an earthing switch.
Le procédé de fabrication comporte les étapes : a) de fixation sur une plaque de montage 6 d' au moins un ensemble comportant un contact de terre 12, un contact de phase 14 et un moyen mobile de connexion électrique 16 entre les contacts de phase 14 et de terre 12, b) de fixation de la plaque de montage 6 sur un boîtier 2 comportant au moins une barre conductrice 8. De manière avantageuse, la connexion du contact de phase 14 avec la barre conductrice 8 s'effectue de manière automatique lors d'un montage de la plaque de montage 6 sur le boîtier 2. Lors de l'étape a), il peut également être prévu de fixer un mécanisme de déplacement 62 du moyen de connexion 16 sur la plaque de montage 6.The manufacturing method comprises the steps of: a) fixing on a mounting plate 6 at least one assembly comprising a ground contact 12, a phase contact 14 and a movable electrical connection means 16 between the phase contacts 14 and earth 12, b) fixing the mounting plate 6 on a housing 2 having at least one conductive bar 8. Advantageously, the connection of the phase contact 14 with the conductive bar 8 takes place automatically when mounting the mounting plate 6 on the housing 2. In step a), it can also be provided to fix a movement mechanism 62 of the connecting means 16 on the mounting plate 6.
Lors de l'étape b) , un moyen d'étanchéité 87 est interposé entre la plaque de montage 6 et le boîtier 2. In step b), a sealing means 87 is interposed between the mounting plate 6 and the housing 2.
