Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention se rapporte au domaine technique des appareillages électriques pour ligne électrique à moyenne, haute ou très haute tension. Plus spécifiquement, l'invention concerne un sectionneur haute tension comprenant un élément rabattable configuré pour la protection et le capotage d'une partie aval sous tension lorsque le sectionneur est en position d'ouverture.The invention relates to the technical field of electrical apparatus for medium, high or very high voltage electrical lines. More specifically, the invention relates to a high-voltage disconnector comprising a folding element configured for the protection and overturning of a downstream portion under voltage when the disconnector is in the open position.

ÉTAT DE LA TECHNIQUE ANTÉRIEURESTATE OF THE PRIOR ART

Les termes « interrupteurs » et « sectionneurs » servent à définir dans ce document des appareillages mécaniques de connexion destinés à mettre hors courant, respectivement hors tension, tout ou partie d'une installation électrique conformément aux définitions de la Commission électrotechnique internationale (CEI).The terms "switches" and "disconnectors" are used to define in this document mechanical switchgear intended to turn off or de-energize all or part of an electrical installation in accordance with the definitions of the International Electrotechnical Commission (IEC).

Un sectionneur haute intensité comprend principalement une partie amont, une partie aval, un conducteur mobile monté mobile par rapport à la partie amont entre une position d'ouverture du sectionneur et une position de fermeture du sectionneur dans laquelle le conducteur mobile relie électriquement la partie amont et la partie aval. Le sectionneur comprend de plus des éléments d'entraînement configurés pour entraîner le conducteur mobile en déplacement entre la position d'ouverture et la position de fermeture.A high intensity disconnector mainly comprises an upstream part, a downstream part, a movable conductor movably mounted with respect to the upstream part between an open position of the disconnector and a closed position of the disconnector in which the mobile conductor electrically connects the upstream part. and the downstream part. The disconnector further comprises drive elements configured to driving the movable conductor moving between the open position and the closed position.

Lors d'opérations de maintenance, du personnel peut avoir à intervenir à proximité du sectionneur.During maintenance operations, personnel may have to intervene near the disconnector.

Afin de protéger ce personnel, des moyens de capotage du sectionneur sont prévus pour recouvrir la partie aval en position d'ouverture. Ces moyens de capotage peuvent notamment comprendre un volet permettant de dégager en position de fermeture du sectionneur une zone de contact de la partie aval contre laquelle le conducteur mobile est configuré pour venir en contact électrique.In order to protect this personnel, the switch disconnecting means are provided to cover the downstream part in the open position. These cowling means may in particular comprise a flap for disengaging in the closed position of the disconnector a contact area of the downstream part against which the movable conductor is configured to come into electrical contact.

Selon un mode de réalisation connu, le sectionneur comprend un volant de manoeuvre distinct des éléments d'entraînement, le volant permettant d'entraîner le volet en déplacement de manière à recouvrir la partie aval.According to a known embodiment, the disconnector comprises a steering wheel separate from the drive elements, the steering wheel for driving the flap in displacement so as to cover the downstream part.

De ce fait, il est nécessaire que le personnel entraîne le déplacement du volet pour recouvrir la partie aval de manière indépendante de la mise en position d'ouverture du sectionneur. Il en résulte un risque supplémentaire d'erreur humaine.Therefore, it is necessary that the staff causes the movement of the shutter to cover the downstream part independently of the opening position of the disconnector. This results in an additional risk of human error.

De tels sectionneurs sont également assez encombrants, présentent un coût assez important et sont relativement complexes d'utilisation pour du personnel intervenant à proximité du sectionneur.Such disconnectors are also quite bulky, have a fairly high cost and are relatively complex to use for personnel working near the disconnector.

Il existe donc un besoin persistant pour un appareillage électrique pour ligne électrique moyenne, haute ou très haute tension d'encombrement limité, de coût raisonnable et susceptible d'améliorer la sécurité du personnel travaillant à proximité de l'appareillage.There is therefore a persistent need for electrical equipment for medium, high or very high voltage electrical line of limited size, of reasonable cost and likely to improve the safety of personnel working near the switchgear.

EXPOSÉ DE L'INVENTIONSTATEMENT OF THE INVENTION

L'invention vise à résoudre les problèmes rencontrés avec les solutions de l'art antérieur. L'invention a notamment pour but de limiter l'encombrement et d'améliorer la sécurité du personnel travaillant à proximité d'un appareillage pour ligne électrique moyenne, haute ou très haute tension de coût raisonnable.The invention aims to solve the problems encountered with the solutions of the prior art. The invention is intended in particular to limit the size and improve the safety of personnel working near a switchgear for medium electrical line, high or very high voltage reasonable cost.

A cet égard, l'invention a pour objet un appareillage électrique pour ligne électrique à moyenne, haute ou très haute tension, notamment un sectionneur à barres, comprenant :

  • une partie amont et une partie aval conductrices,
  • une paire de conducteurs mobiles reliés mécaniquement et électriquement à la partie amont, les conducteurs mobiles étant montés mobiles par rapport à la partie amont entre une position de fermeture de l'appareillage électrique dans laquelle les conducteurs mobiles sont en contact électrique avec la partie aval et une position d'ouverture de l'appareillage électrique dans laquelle les conducteurs mobiles sont à distance et isolés électriquement de la partie aval,
  • une paire d'éléments rabattables réalisés dans au moins un matériau isolant électriquement, les éléments rabattables étant configurés pour pivoter autour d'un axe fixe par rapport à la partie aval,
  • des éléments d'entraînement du conducteur mobile.
In this regard, the subject of the invention is an electrical switchgear for medium, high or very high voltage electrical lines, in particular a bar switch, comprising:
  • an upstream portion and a downstream conductive portion,
  • a pair of movable conductors mechanically and electrically connected to the upstream part, the movable conductors being movably mounted relative to the upstream part between a closed position of the electrical equipment in which the mobile conductors are in electrical contact with the downstream part and an open position of the electrical equipment in which the mobile conductors are remote and electrically isolated from the downstream part,
  • a pair of folding elements made of at least one electrically insulating material, the folding elements being configured to pivot about a fixed axis relative to the downstream portion,
  • drive elements of the mobile conductor.

Les conducteurs mobiles sont reliés mécaniquement aux éléments rabattables et les éléments d'entraînement sont configurés pour entraîner à la fois les éléments rabattables en pivotement par rapport à la partie aval et les conducteurs mobiles en déplacement entre la position de fermeture et la position d'ouverture. Les conducteurs mobiles et les éléments rabattables de chaque paire sont agencés sensiblement symétriquement par symétrie plane par rapport à un même plan.The movable conductors are mechanically connected to the folding elements and the drive elements are configured to drive both the pivotally foldable elements with respect to the downstream part and the movable conductors moving between the closed position and the open position. . The movable conductors and the folding elements of each pair are arranged substantially symmetrically by plane symmetry with respect to the same plane.

Lors de l'ouverture de l'appareillage, chaque élément rabattable en matériau isolant pivote automatiquement pour protéger la partie aval conductrice, notamment lorsqu'elle est sous tension. Ainsi, l'appareillage ne requiert aucune action supplémentaire d'un opérateur pour entraîner l'élément rabattable en pivotement une fois que l'appareillage est en position d'ouverture. L'appareillage selon l'invention permet de ce fait d'assurer une sécurité accrue au personnel travaillant à proximité de l'appareillage.When opening the apparatus, each folding element of insulating material pivots automatically to protect the conductive downstream part, especially when it is under tension. Thus, the apparatus requires no additional action of an operator to drive the folding element pivotally once the apparatus is in the open position. The apparatus according to the invention thus makes it possible to ensure increased safety for personnel working near the apparatus.

L'appareillage ne comporte pas de moyens supplémentaires d'entraînement des éléments rabattables. Par conséquent, les coûts et l'encombrement de l'appareillage sont réduits.The apparatus does not include additional means for driving the folding elements. Consequently, the costs and the size of the apparatus are reduced.

Les deux conducteurs mobiles de l'appareillage permettent une meilleure connexion électrique de la partie amont et de la partie aval en position de fermeture. Les éléments d'entraînement peuvent entraîner sensiblement simultanément chacun des deux éléments rabattables et sensiblement simultanément les deux conducteurs mobiles lors du passage de la position de fermeture à la position d'ouverture.The two mobile conductors of the equipment allow a better connection electrical part of the upstream part and the downstream part in the closed position. The drive elements can substantially simultaneously drive each of the two folding elements and substantially simultaneously the two movable conductors during the transition from the closed position to the open position.

Du fait de la liaison mécanique du conducteur mobile avec les éléments rabattables, le déplacement des conducteurs mobiles entre la position d'ouverture et la position de fermeture et le pivotement des éléments rabattables ont lieu sensiblement simultanément.Because of the mechanical connection of the movable conductor with the folding elements, the movement of the movable conductors between the open position and the closed position and the pivoting of the folding elements take place substantially simultaneously.

Les éléments rabattables pivotent notamment entre une position de capotage de la partie aval correspondant à la position d'ouverture de l'appareillage et une position de décapotage de la partie aval correspondant à une position de fermeture de l'appareillage.The folding elements pivot in particular between a rollover position of the downstream portion corresponding to the open position of the apparatus and a decapoting position of the downstream portion corresponding to a closed position of the apparatus.

Sous l'action des éléments d'entraînement, le déplacement des conducteurs mobiles entre la position d'ouverture et la position de fermeture provoque le pivotement des éléments rabattables entre la position de capotage et la position de décapotage. Réciproquement le pivotement des éléments rabattables entre la position de capotage et la position de décapotage sous l'action des éléments d'entraînement provoque le déplacement des conducteurs mobiles entre la position d'ouverture et la position de fermeture. En particulier, les éléments d'entraînements peuvent entraîner directement les conducteurs mobiles en déplacement entre la position d'ouverture et la position de fermeture ou directement le pivotement des éléments rabattables entre la position de capotage et de décapotage, suivant qu'ils sont reliés mécaniquement directement à l'un ou l'autre de ces éléments.Under the action of the driving elements, the movement of the movable conductors between the open position and the closed position causes the folding elements to pivot between the rollover position and the decapotage position. Conversely, the pivoting of the folding elements between the rollover position and the decapotage position under the action of the drive elements causes the movable conductors to move between the open position and the closed position. In particular, the drive elements can directly drive the moving conductors moving between the open position and the closing position or directly the pivoting of the folding elements between the rollover position and decapotage, depending on whether they are mechanically connected directly to one or the other of these elements.

En position de fermeture, les conducteurs mobiles relient électriquement la partie amont et la partie aval. En position d'ouverture, les conducteurs mobiles sont à distance et isolés électriquement de la partie aval. La partie amont et la partie aval sont alors isolées mécaniquement et électriquement.In the closed position, the mobile conductors electrically connect the upstream portion and the downstream portion. In the open position, the mobile conductors are remote and electrically isolated from the downstream part. The upstream part and the downstream part are then mechanically and electrically isolated.

Par exemple, la partie amont et la partie aval sont configurées pour être reliées à une installation électrique. En position d'ouverture, l'installation électrique est mise au moins partiellement hors tension et/ou au moins partiellement hors courant alors que le courant peut circuler en position de fermeture. En d'autres termes l'appareillage peut servir d'élément de déconnexion d'une installation électrique en position d'ouverture et d'élément de connexion d'une installation électrique en position de fermeture.For example, the upstream portion and the downstream portion are configured to be connected to an electrical installation. In the open position, the electrical installation is at least partially de-energized and / or at least partially de-energized while the current can flow in the closed position. In other words the apparatus can serve as a disconnection element of an electrical installation in the open position and connection element of an electrical installation in the closed position.

De préférence, l'appareillage est sensiblement symétrique par symétrie plane par rapport à un plan médian par la partie amont et la partie aval.Preferably, the apparatus is substantially symmetrical by planar symmetry with respect to a median plane by the upstream portion and the downstream portion.

L'invention peut comporter de manière facultative une ou plusieurs des caractéristiques suivantes combinées entre elles ou non :The invention may optionally include one or more of the following features combined with one another or not:

De préférence, les éléments d'entraînement sont configurés pour entraîner les éléments rabattables indirectement en pivotement par rapport à la partie aval par l'intermédiaire des conducteurs mobiles.Preferably, the driving elements are configured to drive the folding elements indirectly pivotally relative to the downstream portion via the movable conductors.

Dans cette configuration préférée, au moins une partie des éléments d'entraînement sont solidaires des conducteurs mobiles. Les éléments d'entraînement sont alors configurés pour entraîner directement les conducteurs mobiles en déplacement entre la position d'ouverture et la position de fermeture et indirectement les éléments rabattables en pivotement entre la position de capotage et la position de décapotage par liaison mécanique des conducteurs mobiles et des éléments rabattables.In this preferred configuration, at least a portion of the driving elements are integral with the movable conductors. The drive elements are then configured to directly drive the moving conductors moving between the open position and the closed position and indirectly the pivotally foldable elements between the rollover position and the convertible position by mechanical connection of the moving conductors. and folding elements.

De préférence, chaque conducteur mobile et chaque élément rabattable sont reliés par une rainure et un doigt suiveur, le doigt suiveur venant s'engager dans la rainure. Le doigt suiveur et la rainure peuvent être disposés chacun respectivement sur l'élément rabattable ou sur le conducteur mobile ou du moins être solidaires chacun respectivement du conducteur mobile ou de l'élément rabattable. Le doigt suiveur est réalisé par exemple en un matériau isolant électriquement. La rainure est de préférence une rainure traversante.Preferably, each movable conductor and each folding element are connected by a groove and a follower pin, the follower pin engaging in the groove. The follower finger and the groove may each be respectively arranged on the folding element or on the movable conductor or at least each of the movable conductor or the folding element being integral with each other. The follower pin is made for example of an electrically insulating material. The groove is preferably a through groove.

La rainure et le doigt suiveur sont des moyens de guidage robustes mécaniquement qui permettent de limiter l'encombrement de l'appareillage. Ils permettent également un déplacement du conducteur mobile d'amplitude suffisante entre la position d'ouverture et la position de fermeture.The groove and the follower pin are mechanically robust guiding means which make it possible to limit the size of the apparatus. They also allow movement of the movable conductor of sufficient amplitude between the open position and the closed position.

Cependant, la liaison entre un des éléments rabattables et le conducteur mobile auquel il est relié peut comprendre, à la place d'une rainure et d'un doigt suiveur, n'importe quel autre moyen de liaison du conducteur mobile à l'élément rabattable, configuré pour permettre l'ouverture et la fermeture de l'appareillage sous l'action des éléments d'entraînement avec à la fois un déplacement du conducteur mobile entre la position d'ouverture et la position de fermeture et le pivotement de l'élément rabattable entre la position de capotage et la position de décapotage.However, the connection between one of the folding elements and the movable conductor to which it is connected may comprise, in place of a groove and a follower pin, any other connecting means of the movable conductor with the folding element, configured to allow the opening and closing of the apparatus under the action of the drive elements with both a displacement of the movable conductor between the open position and the closed position and pivoting the folding element between the rollover position and the decapotage position.

L'appareillage comprend de préférence deux segments intermédiaires solidaires d'un des conducteurs mobiles et formant de préférence un coude avec les conducteurs mobiles, les conducteurs mobiles de forme oblongue étant reliés mécaniquement aux éléments rabattables par l'intermédiaire des segments intermédiaires.The apparatus preferably comprises two intermediate segments integral with one of the movable conductors and preferably forming a bend with the movable conductors, the oblong-shaped movable conductors being mechanically connected to the folding elements via the intermediate segments.

De préférence, les segments intermédiaires sont en matériau isolant électriquement.Preferably, the intermediate segments are of electrically insulating material.

La configuration de l'appareillage avec des conducteurs mobiles de forme oblongue et des segments intermédiaires permet de limiter les risques de connexion électrique inopinée de la partie amont et de la partie aval en position d'ouverture.The configuration of the apparatus with oblong mobile conductors and intermediate segments makes it possible to limit the risks of unexpected electrical connection of the upstream part and the downstream part in the open position.

De préférence, la partie aval comprend une zone de contact de fermeture avec laquelle les conducteurs mobiles sont en contact électrique en position de fermeture, les éléments rabattables étant configurés pour recouvrir la zone de contact de fermeture en position de capotage.Preferably, the downstream portion comprises a closing contact zone with which the movable conductors are in electrical contact in the closed position, the folding elements being configured to cover the closing contact zone in the rollover position.

Les éléments rabattables peuvent ainsi permettre d'isoler électriquement efficacement la partie aval en position d'ouverture lorsqu'elle reste sous tension. En particulier, les éléments rabattables peuvent limiter le risque de formation d'arcs électriques.The folding elements can thus effectively electrically isolate the downstream portion in the open position when it remains under pressure. In particular, the folding elements can limit the risk of arcing.

De préférence, les éléments rabattables sont configurés pour être en contact mécanique direct avec la zone de contact de fermeture en position d'ouverture de l'appareillage. Ceci permet notamment de réduire l'encombrement de l'appareillage.Preferably, the folding elements are configured to be in direct mechanical contact with the closing contact zone in the open position of the apparatus. This allows in particular to reduce the size of the equipment.

La partie aval est de préférence au moins en partie recouverte par au moins une couche isolante fixe en dehors de la zone de contact de fermeture. Les éléments rabattables et la couche isolante forment alors une protection isolante hermétique de la partie aval en position d'ouverture.The downstream portion is preferably at least partly covered by at least one fixed insulating layer outside the closing contact zone. The folding elements and the insulating layer then form a hermetic insulating protection of the downstream part in the open position.

Les éléments d'entraînement comprennent par exemple un seul moteur entraînant à la fois les conducteurs mobiles en déplacement et les éléments rabattables en pivotement. A titre d'alternative, les éléments d'entraînement peuvent comprendre un seul volant de manoeuvre entraînant à la fois chaque conducteur mobile en mouvement et chaque élément rabattable en pivotement.The drive elements comprise, for example, a single motor driving both the mobile moving conductors and the pivotally folding elements. As an alternative, the drive elements may comprise a single operating wheel driving both each movable conductor in motion and each pivotally foldable element.

L'invention porte aussi sur un élément rabattable pour un appareillage tel que défini ci-dessus, l'élément rabattable comprenant une portion en saillie et une portion emboitable, la portion emboitable étant conformée pour venir, au moins en partie, en contact mécanique direct avec la partie aval en position d'ouverture et pour être à distance de la partie aval en position de fermeture, la portion en saillie comprenant au moins une rainure fermée configurée pour former une butée pour un doigt suiveur.The invention also relates to a folding element for an apparatus as defined above, the folding element comprising a projecting portion and a nestable portion, the engageable portion being shaped to come, at least partly, in direct mechanical contact with the downstream part in the open position and to be at a distance from the downstream part in the closed position, the portion in projection comprising at least one closed groove configured to form a stop for a follower pin.

L'invention concerne également un ensemble comprenant une paire d'éléments rabattables de l'appareillage dont chacun est tel que défini ci-dessus, dans lequel les éléments rabattables sont articulés l'un par rapport à l'autre autour de l'axe fixe de pivotement par rapport à la partie aval, les éléments rabattables de la paire étant de préférence symétriques par symétrie plane de plan comprenant l'axe fixe.The invention also relates to an assembly comprising a pair of folding elements of the apparatus each of which is as defined above, in which the folding elements are hinged relative to one another about the fixed axis pivoting relative to the downstream portion, the folding elements of the pair being preferably symmetrical plane plane symmetry comprising the fixed axis.

Chaque élément rabattable de l'ensemble peut notamment comprendre une portion d'articulation située entre la portion en saillie et la portion emboitable, au niveau de laquelle l'élément rabattable est configuré pour pivoter par rapport à la partie aval.Each folding element of the assembly may include in particular a hinge portion located between the projecting portion and the engageable portion, at which the folding element is configured to pivot relative to the downstream portion.

EXPOSÉ DÉTAILLÉ DE MODES DE RÉALISATION PARTICULIERSDETAILED PRESENTATION OF PARTICULAR EMBODIMENTS

Des parties identiques, similaires ou équivalentes des différentes figures portent les mêmes références numériques de façon à faciliter le passage d'une figure à l'autre.Identical, similar or equivalent parts of the different figures bear the same numerical references so as to facilitate the passage from one figure to another.

Les différentes variantes doivent être comprises comme n'étant pas exclusives les unes des autres et peuvent se combiner entre elles.The different variants must be understood as not being exclusive of each other and can be combined with one another.

La figure 1 représente un appareillage électrique 1 pour une ligne électrique à moyenne, haute ou très haute tension. L'appareillage 1 peut être de diverse nature, par exemple un sectionneur ou un interrupteur-sectionneur. L'appareillage 1 comprend une partie amont 2 et une partie aval 4 conductrices. Les parties amont 2 et aval 4 sont fixées ici sur un support 6.The figure 1 represents an electrical apparatus 1 for a medium, high or very high voltage electrical line. The apparatus 1 may be of various kinds, for example a disconnector or a switch-disconnector. The apparatus 1 comprises an upstream portion 2 and a downstream 4 conductive portion. The upstream and downstream parts 4 are fixed here on a support 6.

L'appareillage 1 est de préférence configuré pour qu'en position d'ouverture de l'appareillage 1, la partie aval 4 puisse rester sous tension alors que la partie amont 2 est déconnectée de toute installation électrique. Cependant, selon une variante de réalisation non représentée, il est tout à fait envisageable de configurer l'appareillage 1 pour que la partie amont 2 reste sous tension de manière indépendante de la partie aval 4 en position d'ouverture, tandis que la partie aval 4 est déconnectée de toute installation électrique.The apparatus 1 is preferably configured so that in the open position of the apparatus 1, the downstream portion 4 can remain energized while the upstream portion 2 is disconnected from any electrical installation. However, according to an alternative embodiment not shown, it is quite possible to configure the apparatus 1 so that the upstream portion 2 remains energized independently of the downstream portion 4 in the open position, while the downstream portion 4 is disconnected from any electrical installation.

Les termes amont et aval sont arbitraires et ne se réfèrent pas nécessairement au sens de parcours du courant électrique. Pour plus de simplicité, les éléments de l'appareillage 1 correspondant par symétrie plane de plan P portent la même référence avec éventuellement adjonction du signe prime (`).The terms upstream and downstream are arbitrary and do not necessarily refer to the direction of travel of the electric current. For simplicity, the elements of the apparatus 1 corresponding planar plane symmetry P have the same reference with possibly addition of the prime sign (`).

L'appareillage 1 comprend également un conducteur mobile 30, 30' qui est relié mécaniquement et électriquement à la partie amont 2. Le conducteur mobile 30, 30' est en permanence relié mécaniquement et électriquement à la partie amont 2 en position de fermeture et en position d'ouverture.The apparatus 1 also comprises a movable conductor 30, 30 'which is mechanically and electrically connected to the upstream part 2. The movable conductor 30, 30' is permanently mechanically and electrically connected to the upstream part 2 in the closed position and in opening position.

Le conducteur mobile 30, 30' est monté mobile par rapport à la partie amont 2 entre une position de fermeture de l'appareillage électrique 1 représentée sur la figure 1 et la figure 5 et une position d'ouverture de l'appareillage électrique 1 représentée sur les figures 2 et 3. Dans le mode de réalisation préféré, le conducteur mobile 30, 30' est de forme oblongue, telle qu'une barre, une succession de barres ou une plaque, en matériau conducteur tel que du métal.The movable conductor 30, 30 'is movably mounted relative to the upstream portion 2 between a closed position of the electrical equipment 1 shown in FIG. figure 1 and the figure 5 and an open position of the electrical equipment 1 shown on the figures 2 and 3 . In the preferred embodiment, the movable conductor 30, 30 'is of oblong shape, such as a bar, a succession of bars or a plate, of conductive material such as metal.

En position de fermeture, le conducteur mobile 30, 30' relie électriquement la partie amont 2 et la partie aval 4. Le conducteur mobile 30, 30' est en contact électrique avec la partie aval 4 en position de fermeture.In the closed position, the movable conductor 30, 30 'electrically connects the upstream part 2 and the downstream part 4. The movable conductor 30, 30' is in electrical contact with the downstream part 4 in the closed position.

En référence plus spécifiquement aux figures 2 et 3, lorsqu'il est en position d'ouverture, le conducteur mobile 30, 30' est à distance et isolé électriquement de la partie aval 4. La partie amont 2 et la partie aval 4 sont alors isolées mécaniquement et électriquement.With reference more specifically to figures 2 and 3 when it is in the open position, the mobile conductor 30, 30 'is remote and electrically isolated from the downstream part 4. The upstream part 2 and the downstream part 4 are then mechanically and electrically isolated.

Le conducteur mobile 30, respectivement 30' est de préférence relié mécaniquement à la partie amont 2 par une liaison pivot au point B, respectivement au point B' comme représenté plus en détail à la figure 2. Les éléments constitutifs de la liaison entre la partie amont 2 et le conducteur mobile 30, 30' sont en grande partie en matériau conducteur afin de permettre un contact électrique permanant de la partie amont 2 et du conducteur mobile 30, 30'.The movable conductor 30, respectively 30 'is preferably mechanically connected to the upstream portion 2 by a pivot connection at the point B, respectively at the point B' as shown in more detail in FIG. figure 2 . The constituent elements of the connection between the upstream part 2 and the movable conductor 30, 30 'are largely of conductive material to allow permanent electrical contact of the upstream portion 2 and the movable conductor 30, 30'.

La liaison mécanique du conducteur mobile 30, 30' avec la partie amont 2 pourrait être différente de celle de la figure 2 du moment qu'elle reste compatible avec un déplacement du conducteur mobile 30, 30' entre une position d'ouverture et une position de fermeture de l'appareillage 1.The mechanical connection of the movable conductor 30, 30 'with the upstream part 2 could be different from that of the figure 2 as long as it remains compatible with a displacement of the movable conductor 30, 30 'between an open position and a closed position of the apparatus 1.

Des opérations de maintenance peuvent avoir lieu lorsque l'appareillage électrique 1 est en position d'ouverture. Il est nécessaire d'isoler électriquement la partie aval 4 de la partie amont 2 et du conducteur mobile 30, 30' en position d'ouverture de l'appareillage 1 afin de protéger le personnel d'intervention.Maintenance operations can take place when the electrical equipment 1 is in the open position. It is necessary to isolate electrically the downstream portion 4 of the upstream portion 2 and the movable conductor 30, 30 'in the open position of the apparatus 1 to protect the emergency personnel.

A cet effet, l'appareillage 1 comprend également un élément rabattable 50, 50', visible notamment en référence aux figures 1 à 5, réalisé dans au moins un matériau isolant électriquement. L'élément rabattable 50, 50' pivote autour d'un axe fixe 13 par rapport à la partie aval 4 entre une position de capotage de la partie aval 4 correspondant à la position d'ouverture de l'appareillage 1 et une position de décapotage de la partie aval 4 correspondant à une position de fermeture de l'appareillage 1.For this purpose, the apparatus 1 also comprises a folding element 50, 50 ', visible in particular with reference to the Figures 1 to 5 made in at least one electrically insulating material. The folding element 50, 50 'pivots about a fixed axis 13 relative to the downstream part 4 between a rollover position of the downstream part 4 corresponding to the open position of the apparatus 1 and a decapotage position of the downstream part 4 corresponding to a closed position of the apparatus 1.

En position de capotage, l'élément rabattable 50, 50' est configuré pour recouvrir au moins une partie 4a, 4a' de la partie aval 4. La partie aval 4 est alors protégée mécaniquement par l'élément rabattable 50, 50'. Elle est également protégée de tout contact électrique avec le conducteur mobile 30, 30' et la partie amont 2 par l'élément rabattable 50, 50'.In the rollover position, the folding element 50, 50 'is configured to cover at least one part 4a, 4a' of the downstream part 4. The downstream part 4 is then mechanically protected by the folding element 50, 50 '. It is also protected from any electrical contact with the movable conductor 30, 30 'and the upstream part 2 by the folding element 50, 50'.

En position de décapotage, l'élément rabattable 50, 50' est configuré pour permettre le contact électrique du conducteur mobile 30, 30' et de la partie aval 4. Dans cette position, en référence à la figure 1 et à la figure 5, l'élément rabattable 50, 50' est de préférence sensiblement replié sur la partie aval 4 de manière symétrique par rapport à l'axe principal 3 de l'appareillage 1.In the uncoupling position, the folding element 50, 50 'is configured to allow the electrical contact of the movable conductor 30, 30' and the downstream part 4. In this position, with reference to FIG. figure 1 and at the figure 5 , the folding element 50, 50 'is preferably substantially folded on the downstream part 4 symmetrically with respect to the main axis 3 of the apparatus 1.

Dans le mode de réalisation préféré, la partie aval 4 comprend une zone de contact de fermeture 4a, 4a' avec laquelle le conducteur mobile 30, 30' est en contact électrique lorsqu'il est en position de fermeture. L'élément rabattable 50, 50' est configuré pour recouvrir la zone de contact de fermeture 4a, 4a' en position de capotage et pour la dégager en position de décapotage.In the preferred embodiment, the downstream portion 4 comprises a closing contact area 4a, 4a 'with which the movable conductor 30, 30' is in electrical contact when in the closed position. The folding element 50, 50 'is configured to cover the closing contact zone 4a, 4a' in the rollover position and to disengage it in the decapoting position.

De préférence, la partie aval 4 est au moins en partie recouverte par au moins une couche isolante fixe 9, 9', visible à la figure 2, dans une zone de protection fixe 4b, 4b' de la partie aval en dehors de la zone de contact de fermeture 4a, 4a'. La zone de protection fixe 4b, 4b'est complémentaire de la zone de contact de fermeture 4a, 4a'. Ces deux zones permettent de préférence de conférer une protection électriquement isolante quasi hermétique à la partie aval 4 en position d'ouverture de l'appareillage 1.Preferably, the downstream portion 4 is at least partly covered by at least one fixed insulating layer 9, 9 ', visible at the figure 2 in a fixed protective zone 4b, 4b 'of the downstream part outside the closing contact zone 4a, 4a'. The fixed protection zone 4b, 4b is complementary to the closing contact zone 4a, 4a '. These two zones preferably make it possible to confer a quasi-hermetic electrically insulating protection to the downstream part 4 in the open position of the apparatus 1.

Dans le mode de réalisation préféré, l'élément rabattable 50, 50' est en contact mécanique direct avec la zone de contact de fermeture 4a, 4a' lorsqu'il est en position de capotage. Selon une variante de réalisation non représentée de l'appareillage 1, l'élément rabattable 50, 50' n'est pas en contact mécanique direct avec la partie aval 4 lorsqu'il est en position de capotage en isolant la partie aval 4 du conducteur mobile 30, 30' et de la partie amont 2.In the preferred embodiment, the folding element 50, 50 'is in direct mechanical contact with the closing contact zone 4a, 4a' when it is in the rollover position. According to a not shown embodiment of the apparatus 1, the folding element 50, 50 'is not in direct mechanical contact with the downstream part 4 when it is in the rollover position by isolating the downstream portion 4 of the driver mobile 30, 30 'and the upstream part 2.

L'élément rabattable 50, 50' est de préférence de forme oblongue tel qu'un volet. Il sera décrit plus en détail en référence à la figure 6.The folding element 50, 50 'is preferably of oblong shape such as a flap. It will be described in more detail with reference to the figure 6 .

L'élément rabattable 50, 50' est relié mécaniquement au conducteur mobile 30, 30'.The folding element 50, 50 'is mechanically connected to the movable conductor 30, 30'.

Dans le mode de réalisation préféré, le conducteur mobile 30, 30' et l'élément rabattable 50, 50' sont reliés mécaniquement par une rainure 55, 57, 55', 57' et un doigt suiveur 33, 35, 33', 35', le doigt suiveur 33, 35, 33', 35' venant s'engager dans la rainure 55, 57, 55', 57'. Le doigt suiveur 33, 35, 33', 35' peut être monté solidaire de l'élément rabattable 50, 50' ou être monté respectivement solidaire du conducteur mobile 30, 30'. La rainure 55, 57, 55', 57' est alors montée par rapport au doigt suiveur 33, 35, 33', 35' solidaire du conducteur mobile 30, 30' ou respectivement solidaire de l'élément rabattable 50, 50'.In the preferred embodiment, the movable conductor 30, 30 'and the folding element 50, 50' are mechanically connected by a groove 55, 57, 55 ', 57' and a follower pin 33, 35, 33 ', 35'.
