Description

Domaine technique de l'inventionTechnical field of the invention

L'invention concerne les dispositifs joint tournant électrique configurés pour équiper des installations d'exploitation de fluides, par exemple d'hydrocarbures, notamment sur des plateformes du type offshore. En particulier, l'invention vise un dispositif joint tournant électrique haute tension.The invention relates to electric rotary joint devices configured to equip installations for the exploitation of fluids, for example hydrocarbons, in particular on platforms of the offshore type. In particular, the invention relates to a high voltage electric rotary joint device.

L'invention vise également une installation d'exploitation de fluides notamment sur une plateforme du type offshore, comportant au moins un tel dispositif joint tournant électrique.The invention also relates to an installation for the exploitation of fluids, in particular on an offshore type platform, comprising at least one such electrical rotating joint device.

Etat de la techniqueState of the art

Les dispositifs joint tournant électrique installés dans des installations sous pression peuvent trouver une application dans les navires de production pétrolières du domaine de l'offshore, permettant l'exploitation de champs d'hydrocarbures en mer. Des unités flottantes de production, de stockage et de déchargement peuvent être formées par un navire qui est mobile, du fait de son environnement, autour d'une tourelle d'amarrage qui est géostationnaire. Le navire peut être assujetti temporairement à la tourelle. Les installations peuvent comporter des conduits qui forment un réseau de canalisations subaquatiques et qui permettent une communication fluidique pour le transfert d'un fluide entre la tourelle et le navire.Electrical rotating joint devices installed in pressurized installations can find an application in oil production vessels in the offshore sector, allowing the exploitation of hydrocarbon fields at sea. Floating production, storage and unloading can be formed by a ship which is mobile, due to its environment, around a mooring turret which is geostationary. The vessel may be temporarily secured to the turret. The installations may include conduits which form a network of underwater pipes and which allow fluid communication for the transfer of a fluid between the turret and the ship.

De tels dispositifs joint tournant électrique peuvent faire partie d'un ensemble joint tournant comportant en outre un empilement de dispositifs joint tournant d'étanchéité (« swivel stack device » en terminologie anglo-saxonne), le dispositif joint tournant électrique étant interposé entre les dispositifs joint tournant d'étanchéité.Such electrical rotating joint devices may form part of a rotating joint assembly further comprising a stack of rotating sealing devices ("swivel stack device" in English terminology), the electrical rotating joint device being interposed between the devices. rotating seal.

De tels dispositifs joint tournant électrique, aussi appelés collecteurs électriques tournants ou bien, en terminologie anglo-saxonne, « electrical swivel devices » sont des dispositifs électromécaniques configurés pour transférer une énergie électrique entre le navire qui est mobile et la tourelle d'amarrage qui est fixe.Such electrical rotating joint devices, also called rotating electrical collectors or, in Anglo-Saxon terminology, “electrical swivel devices” are electromechanical devices configured to transfer electrical energy between the ship which is mobile and the mooring turret which is fixed.

Pour assurer le transfert d'énergie électrique entre le navire et la tourelle, les dispositifs joint tournant électrique sont pourvus d'une première partie, dite fixe, assujettie à la tourelle et d'une deuxième partie, dite mobile, assujettie au navire. La deuxième partie des dispositifs joint tournant électrique est donc mobile par rapport à la première partie des dispositifs joint tournant électrique.To ensure the transfer of electrical energy between the ship and the turret, the electric rotary joint devices are provided with a first part, called fixed, attached to the turret and a second part, called mobile, subject to the vessel. The second part of the electric rotary joint devices is therefore movable relative to the first part of the electric rotary joint devices.

Les dispositifs joint tournant électrique présentent une chambre interne délimitée par les première et deuxième parties. Cette chambre interne est globalement fermée et étanche aux fluides.The electric rotary joint devices have an internal chamber delimited by the first and second parts. This internal chamber is generally closed and fluid-tight.

Les dispositifs joint tournant électrique fonctionnent avec des pistes conductrices circulaires qui sont montées sur l'une des première partie fixe et deuxième partie mobile, dans la chambre interne, et qui coopèrent avec des blocs frotteur qui sont montés sur l'autre des deuxième partie mobile et première partie fixe, dans la chambre interne, afin d'établir des liaisons électriques, notamment selon plusieurs phases électriques.The electric rotary joint devices operate with circular conductive tracks which are mounted on one of the first fixed part and second movable part, in the internal chamber, and which cooperate with friction blocks which are mounted on the other of the second movable part. and first fixed part, in the internal chamber, in order to establish electrical connections, in particular according to several electrical phases.

Les dispositifs joint tournant électrique dits haute tension peuvent par exemple être configurés pour faire transiter des tensions de l'ordre de ou supérieures à 1 500 V en courant continu ou 1 000 V en courant alternatif.So-called high voltage electrical rotating joint devices can for example be configured to pass voltages of the order of or greater than 1,500 V in direct current or 1,000 V in alternating current.

Les dispositifs joint tournant électrique utilisés dans de telles applications offshore doivent répondre à des exigences de qualité prédéterminées pour offrir un certain niveau de sécurité, notamment dans une atmosphère explosive.The electrical rotary joint devices used in such offshore applications must meet predetermined quality requirements to provide a certain level of safety, especially in an explosive atmosphere.

A ces fins, un fluide diélectrique, par exemple de l'huile, est généralement introduit dans la chambre interne à l'intérieur de laquelle sont placés les pistes conductrices et les blocs frotteur associés du dispositif joint tournant électrique.For these purposes, a dielectric fluid, for example oil, is generally introduced into the internal chamber inside which the conductive tracks and the associated friction blocks of the electric rotary joint device are placed.

Un tel fluide diélectrique a classiquement pour fonction d'isoler les pistes conductrices les unes des autres afin d'éviter la formation d'arcs électriques entre une piste conductrice et une piste conductrice voisine, et permet ainsi de réduire la distance entre ces pistes conductrices.Such a dielectric fluid conventionally has the function of insulating the conductive tracks from one another in order to avoid the formation of electric arcs between a conductive track and a neighboring conductive track, and thus makes it possible to reduce the distance between these conductive tracks.

En effet, la distance séparant les pistes conductrices dépend notamment de la rigidité diélectrique du milieu dans lequel elles se trouvent, laquelle rigidité diélectrique s'exprime en kV/mm (kilovolts par millimètre) et caractérise le champ électrique qu'il est possible d'appliquer entre deux électrodes différentes avant qu'il ne se produise un arc électrique et donc qu'un phénomène de claquage apparaisse.In fact, the distance separating the conductive tracks depends in particular on the dielectric strength of the medium in which they are located, which dielectric strength is expressed in kV / mm (kilovolts per millimeter) and characterizes the electric field that it is possible to achieve. apply between two different electrodes before an electric arc occurs and therefore a breakdown phenomenon appears.

Le brevet EP 2 353 213 décrit un tel dispositif joint tournant électrique comportant une première et une seconde parties, mobiles l'une par rapport à l'autre et formant une chambre interne. Chacune des deux parties comporte des connecteurs électriques, des pistes électriques reliées électriquement à des connecteurs de l'une des deux parties et des blocs frotteurs reliés électriquement à des connecteurs de l'autre des deux parties. Les blocs frotteurs coopèrent avec les pistes électriques pour établir des contacts électriques. Les pistes électriques et les blocs frotteurs sont logés dans la chambre interne. La chambre interne est fermée et est remplie d'huile diélectrique ayant une rigidité diélectrique supérieure à celle de l'air environnant le dispositif joint tournant électrique. Au surplus, dans le brevet EP 2 353 213 , le dispositif joint tournant électrique est pourvu d'éléments isolants qui interconnectent les éléments conducteurs et qui sont situés selon un agencement particulier dans la chambre interne.The patent EP 2 353 213 describes such an electric rotary joint device comprising a first and a second part, movable with respect to one another and forming an internal chamber. Each of the two parts comprises electrical connectors, electrical tracks electrically connected to connectors of one of the two parts and friction blocks electrically connected to connectors of the other of the two parts. The friction blocks cooperate with the electrical tracks to establish electrical contacts. The electrical tracks and the friction blocks are housed in the internal chamber. The internal chamber is closed and is filled with dielectric oil having a higher dielectric strength than that of the air surrounding the electric rotary joint device. In addition, in the patent EP 2 353 213 , the electric rotary joint device is provided with insulating elements which interconnect the conductive elements and which are located in a particular arrangement in the internal chamber.

La demande de brevet FR 3 064 122 décrit un autre dispositif joint tournant électrique, comportant une première partie et une seconde partie, mobiles l'une par rapport à l'autre et formant une chambre interne. Chacune des deux parties comporte des connecteurs électriques, des pistes électriques reliées électriquement à des connecteurs de l'une des deux parties et des blocs frotteurs reliés électriquement à des connecteurs de l'autre des deux parties. Les blocs frotteurs coopèrent avec les pistes électriques pour établir des contacts électriques. Les pistes électriques et les blocs frotteurs sont logés dans la chambre interne. La chambre interne est fermée et est remplie d'un gaz d'isolation diélectrique ayant une rigidité diélectrique supérieure à celle de l'air environnant le dispositif joint tournant électrique. L'utilisation d'un tel gaz d'isolation diélectrique autorise une faible fréquence de maintenance liée à la pollution du fluide dans la chambre interne. Au surplus, un tel gaz d'isolation diélectrique voit sa rigidité diélectrique augmenter avec la pression, de sorte qu'un phénomène d'échauffement et donc de surpression survenant dans la chambre interne fermée du dispositif joint tournant électrique améliore la rigidité diélectrique du gaz et réduit encore les risques de claquage.The patent application FR 3 064 122 describes another electric rotary joint device, comprising a first part and a second part, movable with respect to one another and forming an internal chamber. Each of the two parts comprises electrical connectors, electrical tracks electrically connected to connectors of one of the two parts and friction blocks electrically connected to connectors of the other of the two parts. The friction blocks cooperate with the electrical tracks to establish electrical contacts. The electrical tracks and the friction blocks are housed in the internal chamber. The internal chamber is closed and is filled with a dielectric insulating gas having a higher dielectric strength than that of the air surrounding the electric rotary joint device. The use of such a dielectric insulating gas allows a low frequency of maintenance linked to the pollution of the fluid in the internal chamber. In addition, such a dielectric insulating gas sees its dielectric strength increase with pressure, so that a phenomenon of heating and therefore overpressure occurring in the Closed internal chamber of the electric rotary joint device improves the dielectric strength of the gas and further reduces the risk of breakdown.

Exposé de l'inventionDisclosure of the invention

L'invention concerne un dispositif joint tournant électrique, notamment haute tension, configuré pour équiper une installation d'exploitation de fluides, présentant des performances améliorées par rapport aux dispositifs de l'art antérieur susmentionné, tout en étant simple, commode et économique.The invention relates to an electrical rotating joint device, in particular a high voltage device, configured to equip an installation for operating fluids, exhibiting improved performance compared to the devices of the aforementioned prior art, while being simple, convenient and economical.

L'invention a ainsi pour objet, sous un premier aspect, un dispositif joint tournant électrique, notamment haute tension, configuré pour équiper une installation d'exploitation de fluides, par exemple un hydrocarbure et notamment sur une plateforme offshore, comportant une première partie, une deuxième partie mobile en rotation par rapport à ladite première partie, lesdites première partie et deuxième partie formant une chambre interne et étant chacune pourvue d'au moins un connecteur électrique, au moins une piste électrique logée dans ladite chambre interne et reliée électriquement à un dit connecteur de l'une desdites première partie et deuxième partie, au moins un bloc frotteur logé dans ladite chambre interne et relié électriquement à un dit connecteur de l'autre desdites deuxième partie annulaire et première partie, ledit au moins un bloc frotteur coopérant avec ladite au moins une piste électrique pour établir un contact électrique, ladite chambre interne comportant un fluide diélectrique ; caractérisé en ce qu'il comporte un système de génération et d'injection d'un brouillard de fluide diélectrique dans ladite chambre interne, et un système de récupération et de réinjection dudit milieu diélectrique formé dudit fluide diélectrique et dudit brouillard de fluide diélectrique dans ladite chambre interne.The subject of the invention is thus, in a first aspect, an electrical rotating joint device, in particular high voltage, configured to equip an installation for the exploitation of fluids, for example a hydrocarbon and in particular on an offshore platform, comprising a first part, a second part movable in rotation with respect to said first part, said first part and second part forming an internal chamber and each being provided with at least one electrical connector, at least one electrical track housed in said internal chamber and electrically connected to a said connector of one of said first part and second part, at least one friction block housed in said internal chamber and electrically connected to one said connector of the other of said second annular part and first part, said at least one friction block cooperating with said at least one electrical track for establishing electrical contact, said internal chamber comprising a di fluid electric; characterized in that it comprises a system for generating and injecting a mist of dielectric fluid into said internal chamber, and a system for recovering and reinjecting said dielectric medium formed from said dielectric fluid and said mist of dielectric fluid into said internal chamber.

Le dispositif joint tournant électrique selon l'invention comporte, dans sa chambre interne, un milieu diélectrique formé au moins par le mélange d'un liquide diélectrique et/ou d'un gaz diélectrique, avec un brouillard de fluide diélectrique.The electric rotary joint device according to the invention comprises, in its internal chamber, a dielectric medium formed at least by the mixture of a dielectric liquid and / or a dielectric gas, with a dielectric fluid mist.

Un tel milieu diélectrique permet, en plus de sa fonction d'isolation électrique, de nettoyer la chambre interne de particules polluantes pouvant s'y trouver, lesquelles particules polluantes ont tendance à diminuer la rigidité diélectrique du milieu diélectrique.Such a dielectric medium makes it possible, in addition to its electrically insulating function, to clean the internal chamber of polluting particles which may be there, which polluting particles tend to reduce the dielectric strength of the dielectric medium.

A noter que cette pollution résulte d'une part de l'usure des pièces en mouvement, principalement des frotteurs, et d'autre part des décharges électriques partielles dans la chambre interne.Note that this pollution results on the one hand from the wear of moving parts, mainly the wipers, and on the other hand from partial electric discharges in the internal chamber.

Le brouillard de fluide diélectrique permet non seulement de réduire la génération des phénomènes de claquage en augmentant la rigidité diélectrique du milieu diélectrique, mais aussi de capter les particules polluantes qui peuvent se trouver en suspension dans le liquide diélectrique et/ou dans le gaz diélectrique du milieu diélectrique et/ou qui peuvent se trouver sur des parois internes des première et/ou deuxième parties annulaires.The mist of dielectric fluid not only makes it possible to reduce the generation of breakdown phenomena by increasing the dielectric strength of the dielectric medium, but also to capture the polluting particles which may be in suspension in the dielectric liquid and / or in the dielectric gas of the dielectric medium and / or which may be on internal walls of the first and / or second annular portions.

Ceci permet de nettoyer la chambre interne et le milieu diélectrique s'y trouvant. Un tel nettoyage de la chambre interne et du milieu diélectrique qu'elle comporte favorise encore la réduction de formation d'arcs électriques dans le temps au sein du dispositif joint tournant électrique.This makes it possible to clean the internal chamber and the dielectric medium therein. Such cleaning of the internal chamber and of the dielectric medium that it comprises further promotes the reduction in the formation of electric arcs over time within the electric rotary joint device.

Ceci permet en outre de réduire et donc d'espacer les opérations de maintenance d'un tel dispositif joint tournant électrique, lesquelles opérations sont souvent compliquées par la localisation d'un tel dispositif joint tournant électrique, en particulier s'il se trouve dans un empilement de dispositifs joint tournant d'étanchéité.This also makes it possible to reduce and therefore to space out the maintenance operations of such an electric rotary joint device, which operations are often complicated by the location of such an electric rotary joint device, in particular if it is in a stack of rotating seal devices.
