Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention propose un appareillage électrique pour une ligne de transport de courant électrique à haute tension, tel qu'un sectionneur de mise à la terre, un sectionneur ou un disjoncteur, comportant des moyens pour retarder le moment d'apparition d'un arc électrique lors d'une phase de fermeture de l'appareillage électrique et pour limiter la durée d'un tel arc lors d'une phase de fermeture ou d'ouverture de l'appareillage électrique.The invention provides an electrical apparatus for a high voltage electrical power transmission line, such as an earthing switch, a disconnector or a circuit breaker, including means for delaying the moment of appearance of an arc. during a closing phase of the electrical equipment and to limit the duration of such an arc during a closing phase or opening of the electrical equipment.

ÉTAT DE LA TECHNIQUE ANTÉRIEURESTATE OF THE PRIOR ART

Un appareillage électrique pour une ligne de transport de courant électrique à haute tension tel que par exemple un sectionneur pour une ligne de transport à haute tension est un appareil de sécurité qui a pour but d'établir une isolation électrique entre des parties sous tension.An electrical apparatus for a high voltage electrical power transmission line such as for example a disconnector for a high voltage transmission line is a safety device which aims to establish electrical isolation between live parts.

L'appareillage électrique comporte un contact amont et un contact aval, qui sont aptes à être mis en contact ou à être séparés, selon que l'on veut établir ou non une connexion électrique entre les deux parties sous tension.The electrical equipment comprises an upstream contact and a downstream contact, which are able to be brought into contact or to be separated, depending on whether or not an electrical connection is to be established between the two parts under tension.

L'appareillage comporte aussi une enceinte fermée conductrice électriquement, dans laquelle les contacts sont reçus, et cette enceinte est remplie d'un gaz isolant électriquement tel que par exemple de l'hexafluorure de soufre SF6 ou un mélange gazeux sous pression, permettant de limiter la formation de l'arc électrique.The apparatus also comprises an electrically conductive closed enclosure, in which the contacts are received, and this enclosure is filled with an electrically insulating gas such as, for example, sulfur hexafluoride SF6 or a gaseous mixture under pressure, to limit the formation of the electric arc.

Lors de la fermeture ou de l'ouverture de l'appareillage électrique, du fait de la différence de potentiel entre les contacts, un ou plusieurs arcs électriques se forment entre les deux contacts. Ces arcs entre contacts peuvent comporter des ramifications radiales qui, dans certaines conditions, risquent de se propager radialement et atteindre l'enceinte conductrice environnante.When closing or opening the electrical equipment, because of the potential difference between the contacts, one or more arcs are formed between the two contacts. These arcs between contacts may have radial branches which, under certain conditions, may propagate radially and reach the surrounding conductive enclosure.

Ces arcs électriques radiaux endommagent fortement l'enceinte puisque un court-circuit s'établit dans l'occurrence d'un tel événement.These radial electric arcs strongly damage the enclosure since a short circuit is established in the occurrence of such an event.

Il est donc important de diminuer les causes d'apparition de ces ramifications radiales des arcs électriques pour ne pas qu'elles atteignent l'enveloppe.It is therefore important to reduce the causes of appearance of these radial branches of electric arcs so that they do not reach the envelope.

C'est pourquoi il a été recherché des solutions qui permettent de limiter les possibilités d'apparition des arcs électriques, ou bien les solutions qui permettent de réduire la durée d'existence d'un arc électrique pour réduire ainsi la probabilité qu'une ramification de l'arc atteigne la cuve, ou encore des solutions concernant l'environnement de l'arc électrique principal qui permettent de contrôler les ramifications radiales.This is why solutions have been sought to limit the possibilities of occurrence of arcing, or solutions that reduce the duration of the existence of an electric arc to reduce the probability of branching. the arc reaches the tank, or solutions concerning the environment of the main electric arc that can control the radial branches.

Une solution permettant en partie de limiter l'apparition des ramifications radiales des arcs électriques consiste à d'augmenter la vitesse de déplacement du contact mobile. Cependant, cela implique de concevoir des moyens d'entraînement de grandes dimensions, augmentant par conséquent les coûts de l'appareillage. Par ailleurs il est également connu que l'ouverture rapide d'un sectionneur sur une portion de jeux de barre à vide peut induire une charge électrique dite "piégée" qui est plus importante que dans le cas d'une manouvre lente. Cela augmente la probabilité de voir un arc se développer en direction de la cuve à la manoeuvre de fermeture suivante.A solution that makes it possible in part to limit the appearance of the radial branches of the electric arcs consists in increasing the speed of movement of the moving contact. However, this involves designing large training means dimensions, thus increasing the cost of fitting. Furthermore, it is also known that the rapid opening of a disconnector on a portion of vacuum bar sets can induce a so-called "trapped" electrical charge which is greater than in the case of a slow maneuver. This increases the likelihood of an arc developing towards the tank at the next closing maneuver.

Le document DE 32 37 146 A1 divulgue un appareillage à haute tension selon le préambule de la revendication 1.The document DE 32 37 146 A1 discloses a high voltage switchgear according to the preamble of claim 1.

L'invention a pour but de proposer un appareillage électrique réalisé de manière à limiter les risques d'apparitions de ramifications radiales des arcs électriques, pour optimiser la fiabilité de l'appareillage lors d'une étape d'ouverture ou de fermeture de l'appareillage en améliorant les capacités du dispositif selon les trois points cités ci -dessus.The object of the invention is to propose electrical equipment designed to limit the risk of occurrence of radial branches of electric arcs, to optimize the reliability of the equipment during a step of opening or closing the apparatus by improving the capabilities of the device according to the three points mentioned above.

Selon le mode de réalisation représenté aux figures 1 à 5, le contact amont 12 et le contact aval 22 consistent chacun ici en une tige axiale qui s'étend axialement et la face d'extrémité amont 22a du contact aval 22 est apte à venir en contact permanent avec la face d'extrémité aval 12a en vis-à-vis du contact fixe 12 lorsque l'appareillage est dans une position de fermeture.According to the embodiment shown in Figures 1 to 5 , the upstream contact 12 and the downstream contact 22 each consist of an axially extending axial shaft and the upstream end face 22a of the downstream contact 22 is able to come into permanent contact with the downstream end face 12a. vis-à-vis the fixed contact 12 when the equipment is in a closed position.

Dans la présente description de l'invention, il sera compris que le terme "tige" utilisé peut désigner aussi bien une tige pleine qu'une tige creuse ou tubulaire.In the present description of the invention, it will be understood that the term "rod" used may designate both a solid rod and a hollow or tubular rod.

Selon le mode de réalisation représenté à la figure 6, le contact amont 12 a une forme tubulaire et le contact aval 22 comporte une tige radialement interne 14 et une portion tubulaire 16 entourant la tige interne 14.According to the embodiment shown in figure 6 the upstream contact 12 has a tubular shape and the downstream contact 22 has a radially inner rod 14 and a tubular portion 16 surrounding the inner rod 14.

L'extrémité amont 14a de la tige 14 est définie de manière à être reçue sans jeu à l'intérieur du contact amont 12, lorsque les contacts amont 12 et aval 22 sont raccordés l'un à l'autre, comme on le verra plus en détails par la suite.The upstream end 14a of the rod 14 is defined to be received without play inside the upstream contact 12, when the upstream 12 and downstream contacts 22 are connected to each other, as will be seen more in detail later.

L'appareillage 10 comporte aussi un corps fixe 20 par l'intermédiaire duquel le contact aval 22 est guidé en translation axiale. Le corps fixe 20 est réalisé en un matériau conducteur électriquement et est raccordé au potentiel électrique terrestre. Un support en matériau isolant 18 permet d'isoler électriquement le corps fixe d'avec le contact aval 22.The apparatus 10 also comprises a fixed body 20 through which the downstream contact 22 is guided in axial translation. The fixed body 20 is made of an electrically conductive material and is connected to the earth's electrical potential. An insulating material support 18 makes it possible to electrically isolate the fixed body from the downstream contact 22.

Lors de la fermeture de l'appareillage 10, le contact aval 22 se déplace axialement vers l'amont en direction du contact amont 12, à partir d'une première position aval d'ouverture de l'appareillage 10 représentée aux figures 1 et 6, dans laquelle le contact aval 22 est situé à distance du contact amont 12.When closing the apparatus 10, the downstream contact 22 moves axially upstream towards the upstream contact 12, from a first downstream opening position of the apparatus 10 shown in FIGS. figures 1 and 6 , in which the downstream contact 22 is situated at a distance from the upstream contact 12.

Dans une certaine position axiale représentée à la figure 4, qui est située axialement entre la position aval d'ouverture et la position amont de fermeture de l'appareillage 10, le contact aval 22 vient en contact avec le contact amont 12. Dans cette position axiale dite de contact, les deux contacts 12, 22 sont directement raccordés l'un à l'autre.In a certain axial position represented in the figure 4 , which is situated axially between the downstream opening position and the upstream closing position of the apparatus 10, the downstream contact 22 comes into contact with the upstream contact 12. In this so-called axial contact position, the two contacts 12, 22 are directly connected to each other.

Lors du déplacement du contact aval 22 entre la position d'ouverture représentée à la figure 1 et la position de contact représentée à la figure 4, des arcs électriques peuvent se former entre les deux contacts 12, 22 et des arcs électriques secondaires peuvent se former entre les contacts 12, 22 et le corps 20 à partir de ces arcs électriques.When moving the downstream contact 22 between the open position shown in FIG. figure 1 and the contact position shown in the figure 4 , electric arcs can be formed between the two contacts 12, 22 and secondary electric arcs may be formed between the contacts 12, 22 and the body 20 from these arcs.

Pour limiter la formation de ces arcs électriques secondaires, l'appareillage 10 comporte une électrode aval 30 qui est montée au niveau de l'extrémité aval de l'appareillage 10 et une électrode amont 32 qui est montée au niveau de l'extrémité amont de l'appareillage 10.To limit the formation of these secondary arcs, the apparatus 10 comprises a downstream electrode 30 which is mounted at the downstream end of the apparatus 10 and an upstream electrode 32 which is mounted at the upstream end of the apparatus. the apparatus 10.

L'électrode aval 30 consiste en un élément de révolution qui entoure le contact aval 22. L'électrode aval 30 comporte une face amont 30a s'étendant principalement radialement qui fait face au contact amont 12 et à l'électrode amont 32.The downstream electrode 30 consists of an element of revolution which surrounds the downstream contact 22. The downstream electrode 30 has a radially extending upstream face 30a which faces the upstream contact 12 and the upstream electrode 32.

L'électrode amont 32 est de forme similaire à la forme de l'électrode aval 30. Elle consiste en un élément de révolution qui entoure le contact amont 12 et elle comporte une face aval 32a s'étendant principalement radialement qui fait face à la face amont 30a de l'électrode aval 30.The upstream electrode 32 is similar in shape to the shape of the downstream electrode 30. It consists of a revolution element which surrounds the upstream contact 12 and has a downstream face 32a extending mainly radially facing the face. upstream 30a of the downstream electrode 30.

L'électrode aval 30 est montée mobile axialement par rapport au corps 20 entre une position aval représentée à la figure 1, dans laquelle la face amont 30a de l'électrode aval 30 affleure avec la face amont 22a du contact mobile 22 et une position amont représentée aux figures 2 et suivantes.The downstream electrode 30 is mounted axially movable relative to the body 20 between a downstream position represented at figure 1 , in which the upstream face 30a of the downstream electrode 30 is flush with the upstream face 22a of the movable contact 22 and an upstream position shown in FIGS. figures 2 and following.

L'électrode aval 30 se déplace axialement de manière synchronisée avec le déplacement axial du contact aval 22 à partir de la position aval jusqu'à une position intermédiaire représentée à la figure 2 dans laquelle l'électrode aval 30 est dans sa position extrême amont.The downstream electrode 30 moves axially in synchronism with the axial displacement of the downstream contact 22 from the downstream position to an intermediate position shown in FIG. figure 2 in which the downstream electrode 30 is in its extreme upstream position.

Selon l'invention, le contact aval 22 se déplace axialement vers l'amont au-delà de la position de contact représentée à la figure 4, vers une position de fermeture de l'appareillage 10 représentée à la figure 5.According to the invention, the downstream contact 22 moves axially upstream beyond the contact position shown in FIG. figure 4 towards a closed position of the apparatus 10 shown in FIG. figure 5 .

Lorsque le contact aval 22 est dans la position de fermeture de l'appareillage 10, il est simultanément en contact avec le contact amont 12 et l'électrode amont 32.When the downstream contact 22 is in the closed position of the apparatus 10, it is simultaneously in contact with the upstream contact 12 and the upstream electrode 32.

Les deux électrodes sont ainsi raccordée électriquement l'une avec l'autre par l'intermédiaire du contact aval 12.The two electrodes are thus electrically connected to one another via the downstream contact 12.

Lors de ce déplacement entre la position de contact et la position de fermeture, le contact aval 22 est en permanence en contact avec le contact amont 12, pour éviter toute apparition d'un arc électrique dans l'appareillage.During this movement between the contact position and the closed position, the downstream contact 22 is permanently in contact with the upstream contact 12, to avoid any occurrence of an electric arc in the equipment.

Selon un premier mode de réalisation de l'invention, le contact amont 12 est apte à se déplacer vers l'amont, simultanément avec le contact aval 22.According to a first embodiment of the invention, the upstream contact 12 is able to move upstream, simultaneously with the downstream contact 22.

A cet effet, le contact amont 12 est monté mobile par rapport au corps fixe 20 entre une position aval représentée aux figures 1 à 4, et une position amont représentée à la figue 5.For this purpose, the upstream contact 12 is mounted to move relative to the fixed body 20 between a downstream position shown in FIGS. Figures 1 to 4 , and an upstream position shown in FIG.

L'entraînement du contact amont 12 depuis sa position aval vers sa position amont est réalisé par l'intermédiaire du contact aval 22, de manière telle que le déplacement des deux contacts 12, 22 est simultané.The drive of the upstream contact 12 from its downstream position to its upstream position is performed via the downstream contact 22, so that the displacement of the two contacts 12, 22 is simultaneous.

L'entraînement du contact amont 12 depuis sa position amont vers sa position aval est réalisé par exemple par des moyens élastiques (non représentés) tels qu'un ressort de compression par exemple. Les moyens élastiques exercent sur le contact amont 12 une action continue d'entraînement du contact amont 12 vers sa position aval.The drive of the upstream contact 12 from its upstream position to its downstream position is carried out by example by elastic means (not shown) such as a compression spring for example. The elastic means exert on the upstream contact 12 a continuous action of driving the upstream contact 12 to its downstream position.

Ainsi, les moyens élastiques permettent de maintenir le contact amont 12 et le contact aval 22 en contact l'un avec l'autre lors de leurs déplacements vers l'amont ou vers l'aval entre la position de contact et la position de fermeture de l'appareillage 10.Selon un deuxième mode de réalisation de l'invention représenté à la figure 6, le contact amont 12 reste immobile lorsque le contact aval 22 se déplace entre la position de contact et la position de fermeture de l'appareillage 10.Thus, the elastic means make it possible to maintain the upstream contact 12 and the downstream contact 22 in contact with each other during their upstream or downstream displacements between the contact position and the closed position of the 10. According to a second embodiment of the invention shown in figure 6 the upstream contact 12 remains stationary when the downstream contact 22 moves between the contact position and the closed position of the apparatus 10.

Comme on l'a dit précédemment, le raccordement électrique entre le contact amont 12 et le contact aval 22 est réalisé par l'intermédiaire de la tige 14 dont l'extrémité libre 14a est reçue sans jeu dans le contact amont 12. Pour que le contact électrique soit maintenu entre les deux contacts électriques, la forme interne du contact amont 12 est cylindrique, pour permettre un coulissement axial vers l'amont de l'extrémité libre 14a de la tige 14, tout en maintenant un contact électrique.As mentioned above, the electrical connection between the upstream contact 12 and the downstream contact 22 is made via the rod 14 whose free end 14a is received without play in the upstream contact 12. electrical contact is maintained between the two electrical contacts, the inner shape of the upstream contact 12 is cylindrical, to allow axial sliding upstream of the free end 14a of the rod 14, while maintaining an electrical contact.

Le raccordement électrique entre le contact aval 22 et l'électrode amont 32 est réalisé par le contact entre une face cylindrique externe du contact aval 22 et une face cylindrique interne complémentaire de l'électrode amont 32.The electrical connection between the downstream contact 22 and the upstream electrode 32 is formed by the contact between an outer cylindrical face of the downstream contact 22 and an inner cylindrical face complementary to the upstream electrode 32.

Selon le mode de réalisation représenté aux figures 1 à 5, cette face cylindrique externe du contact aval 22 est sa face externe. Selon le mode de réalisation représenté aux figures 1 à 5, cette face cylindrique externe du contact aval 22 est la face externe de la portion tubulaire 16 entourant la tige interne 14. Comme on l'a décrit précédemment, le contact aval 22 et l'électrode aval se déplacent de manière synchronisée façon coordonnée, de préférence, ils se déplacent de manière simultanée.According to the embodiment shown in Figures 1 to 5 this outer cylindrical face of the downstream contact 22 is its external face. According to the embodiment shown in Figures 1 to 5 this external cylindrical face of the downstream contact 22 is the external face of the tubular portion 16 surrounding the inner rod 14. As described above, the downstream contact 22 and the downstream electrode move in a synchronized manner in a coordinated fashion, preferably, they move simultaneously.

Lors du déplacement simultané du contact aval 22 et de l'électrode aval 30, selon un mode de réalisation préféré mais non limitatif, leurs faces amont respectives 22a, 30a sont toujours à la même cote axiale l'une par rapport à l'autre, le long de l'axe principal A.During the simultaneous displacement of the downstream contact 22 and the downstream electrode 30, according to a preferred but non-limiting embodiment, their respective upstream faces 22a, 30a are always at the same axial dimension with respect to each other, along the main axis A.

Ainsi, elles se rapprochent simultanément des faces aval respectives 12a, 32a du contact amont 12 et de l'électrode amont 32, de manière à limiter la formation des arcs secondaires radiaux entre le contact amont 12 et le corps fixe 20.Thus, they are simultaneously approaching respective downstream faces 12a, 32a of the upstream contact 12 and the upstream electrode 32, so as to limit the formation of the radial secondary arcs between the upstream contact 12 and the fixed body 20.

Lorsque le contact aval 22 et l'électrode aval 30 atteignent la position intermédiaire représentée à la figure 2, il est considéré que les arcs secondaires radiaux ne peuvent plus se former.When the downstream contact 22 and the downstream electrode 30 reach the intermediate position shown in FIG. figure 2 it is considered that the radial secondary arches can no longer be formed.

A partir de cette position intermédiaire, seul le contact aval 22 se déplace vers l'amont, comme on peut le voir notamment à la figure 3, indépendamment de l'électrode aval 30. La face amont 22a du contact aval fait alors saillie axialement vers l'amont par rapport à la face amont 30a de l'électrode aval 30.From this intermediate position, only the downstream contact 22 moves upstream, as can be seen in particular in FIG. figure 3 , independently of the downstream electrode 30. The upstream face 22a of the downstream contact then projects axially upstream with respect to the upstream face 30a of the downstream electrode 30.

Des arcs électriques sont aptes à se former entre le contact amont 12 et le contact aval 22. Ces deux composants 12, 22 sont conçus de manière à pouvoir supporter les contraintes provenant de ces arcs électriques.Electrical arcs are formed between the upstream contact 12 and the downstream contact 22. These two components 12, 22 are designed to be able to withstand the stresses from these arcs.

Ensuite, le contact aval 22 vient en contact avec le contact amont 12, comme représenté à la figure 4 puis, comme décrit précédemment, le contact aval 22 se déplacent en direction la position amont de fermeture de l'appareillage 10, simultanément avec le contact amont 12 selon le premier mode de réalisation de l'invention représenté à la figure 5, ou bien en coulissement par rapport au contact amont selon le mode de réalisation représenté à la figure 6.Then, the downstream contact 22 comes into contact with the upstream contact 12, as shown in FIG. figure 4 then, as previously described, the downstream contact 22 move towards the upstream closing position of the apparatus 10, simultaneously with the upstream contact 12 according to the first embodiment of the invention shown in FIG. figure 5 , or in sliding relative to the upstream contact according to the embodiment shown in FIG. figure 6 .

Le contact aval 22 vient alors en contact avec l'électrode amont 32, fermant ainsi l'appareillage 10.The downstream contact 22 then comes into contact with the upstream electrode 32, thus closing the apparatus 10.

L'ouverture de l'appareillage 10 s'effectue selon un mouvement inverse du contact amont 12, du contact aval 22 et de l'électrode aval 30, c'est-à-dire en passant successivement de l'état représenté à la figure 5 à l'état représenté à la figure 1.The apparatus 10 is opened in a reverse movement of the upstream contact 12, the downstream contact 22 and the downstream electrode 30, that is to say by successively passing from the state shown in FIG. figure 5 in the state shown in figure 1 .

Ainsi, selon un premier mouvement, le contact amont 12 se déplace vers l'aval jusqu'à la position de contact représentée à la figure 4.Thus, in a first movement, the upstream contact 12 moves downstream to the contact position shown in FIG. figure 4 .

Le contact électrique entre le contact aval 22 et l'électrode amont 32, puis le contact électrique enter le contact amont 12 et le contact aval 22 sont rompus l'un après l'autre, permettant la formation d'arcs électriques.The electrical contact between the downstream contact 22 and the upstream electrode 32, then the electrical contact enter the upstream contact 12 and the downstream contact 22 are broken one after the other, allowing the formation of electric arcs.

Ensuite, le contact aval 22 atteint la position intermédiaire représentée à la figure 2 dans laquelle sa face d'extrémité amont 22a est à la même cote axiale que la face d'extrémité amont 30a de l'électrode aval 30.Then the downstream contact 22 reaches the intermediate position shown in FIG. figure 2 in which its upstream end face 22a is at the same axial dimension as the upstream end face 30a of the downstream electrode 30.

A partir de cette position intermédiaire, le contact aval 22 et l'électrode aval 30 se déplacent simultanément vers l'aval jusqu'à la position d'ouverture de l'appareillage 10 représenté à la figure 1. Pendant ce déplacement simultané du contact aval 22 et de l'électrode aval 30, leurs faces d'extrémité amont 22a et 30a sont toujours à la même cote axiale l'une par rapport à l'autre, limitant la formation des arcs électriques radiaux.From this intermediate position, the downstream contact 22 and the downstream electrode 30 move simultaneously downstream to the open position of the apparatus 10 shown in FIG. figure 1 . During this simultaneous movement of the downstream contact 22 and the downstream electrode 30, their upstream end faces 22a and 30a are always at the same axial dimension with respect to each other, limiting the formation of the radial electric arcs.
