Description
La présente invention se rapporte à un connecteur de deux câbles d'énergie électrique et une connexion comportant un tel connecteur.The present invention relates to a connector of two cables of electrical energy and a connection comprising such a connector.
Elle concerne plus précisément un connecteur de deux câbles d'énergie électrique de moyenne tension, comportant chacun un conducteur entouré d'une enveloppe isolante et éventuellement d'une couche semi-conductrice, connecteur comportant des contacts vissés tubulaires et destiné à connecter ensemble les extrémités mises à nu desdits conducteurs engagés dans lesdits contacts et maintenues au moyen de vis.It relates more precisely to a connector of two cables medium voltage electrical energy, each with a conductor surrounded by an insulating jacket and possibly a semiconductor layer, connector with screwed tubular contacts and intended connecting together the exposed ends of said conductors engaged in said contacts and held in place by screws.
Une connexion de câble comportant un tel connecteur est connue du
document de brevet GB 2 254 739. Le connecteur utilisé dans cette
connexion de câble connue est couvert d'une gaine isolante rétractable à
chaud. La gaine est positionnée au-dessus du connecteur et est rétractée
par chauffage puis, après l'opération de chauffage, reste en position
rétractée. Cette gaine tend donc à prendre la forme du connecteur qui est en
dessous d'elle et de l'enveloppe isolante de chacun des câbles. Cependant,
il reste toujours des espaces libres aux emplacements où le diamètre
change, c'est-à-dire entre l'enveloppe isolante et le connecteur, ainsi que des
espaces libres à cause de l'irrégularité de forme du connecteur, en particulier
les têtes des vis. Dans cette solution connue, pour combler les espaces
libres, une feuille de mastic isolant est enroulé autour du connecteur avant la
rétraction de la gaine.A cable connection comprising such a connector is known from
La différence de diamètre entre l'enveloppe isolante et le connecteur
est essentiellement due au fait que cet ensemble de contacts vissés couvre
généralement une plage importante de sections, par exemple de 50 à 300
mm2, et est donc plus grande que l'enveloppe isolante de chaque câble. Un
tel connecteur vissé est par exemple connu du document de brevet GB 2 262
396. De plus, le connecteur a une disposition excentrée par rapport au
conducteur. Ceci est dû à la présence des vis qui augmentent encore la
différence dimensionnelle entre l'enveloppe isolante et le connecteur. Les
têtes des vis et des taraudages font des points vifs sur la surface du
connecteur. Le résultat est que la gaine isolante ne peut pas suivre
fidèlement les contours de l'enveloppe isolante de chaque câble et des
surfaces du connecteur, et que le mastic isolant est exposé à un champ
électrique trop important juste aux emplacements les plus critiques sur le
plan électrique. Ceci est un problème qui peut mener au claquage de la
connexion surtout pour des applications à partir de 10 kVolts.The difference in diameter between the insulating jacket and the connector is essentially due to the fact that this set of screwed contacts generally covers a large range of sections, for example from 50 to 300 mm 2 , and is therefore larger than the insulating jacket. of each cable. Such a screwed connector is for example known from
Une solution a été proposée qui est décrite dans le document de brevet EP 1 206 024.A solution has been proposed which is described in the document of EP patent 1 206 024.
Selon cette solution antérieure, la connexion est pourvue de deux capots moulés en caoutchouc semi-conducteur couvrant une partie de l'enveloppe isolante du câble correspondant et se rejoignant l'un l'autre au-dessus du connecteur, chacun desdits capots ayant une forme interne adaptée pour être engagé au-dessus du connecteur et pour remplir l'espace formé par la différence de dimension entre le connecteur et l'enveloppe isolante du câble correspondant.According to this previous solution, the connection is provided with two molded semi-conductive rubber covers covering part of the insulating jacket of the corresponding cable and joining each other above of the connector, each of said covers having an internal shape adapted to be engaged above the connector and to fill the space formed by the difference in dimension between the connector and the casing insulator of the corresponding cable.
Un tel agencement fournit un résultat électrique satisfaisant mais est de montage problématique. En effet, ces deux capots séparés entre eux et séparés du connecteur doivent être enfilés sur les extrémités de câble avant réalisation de la connexion des câbles par le connecteur et ensuite repoussés sur le connecteur avant mise en place de la gaine isolante.Such an arrangement provides a satisfactory electrical result but is problematic mounting. Indeed, these two covers separated from each other and separate from connector must be threaded over front cable ends connection of cables through the connector and then pushed back onto the connector before fitting the insulating sheath.
Il a par ailleurs été proposé dans le document de brevet DE 27 40 232 un connecteur de deux câbles d'énergie électrique, comportant chacun un conducteur entouré d'une enveloppe isolante, connecteur comportant des contacts vissés tubulaires et destiné à connecter ensemble les extrémités mises à nu des conducteurs engagées dans les contacts et maintenues au moyen de vis. Ce connecteur comporte à ses extrémités un prolongement faisant partie du connecteur et destiné à couvrir une partie de l'enveloppe isolante du câble. Ce recouvrement est d'une longueur de l'ordre de quelques millimètres.It has also been proposed in patent document DE 27 40 232 a connector of two electric power cables, each comprising a conductor surrounded by an insulating envelope, connector comprising tubular screw contacts and intended to connect the ends together exposed conductors engaged in the contacts and kept at screw means. This connector has an extension at its ends forming part of the connector and intended to cover part of the casing cable insulator. This overlap has a length of the order of a few millimeters.
Sur les câbles à moyenne tension, l'enveloppe isolante peut se rétracter sur plusieurs millimètres et jusqu'à 10 mm. Un tel connecteur n'est donc pas adapté à assurer ce recouvrement dans le temps et en cas de retrait de l'enveloppe isolante, retrait en soi classique sur ce type de câbles, un espace vide se crée propice aux claquages comme il a été vu plus haut.On medium voltage cables, the insulating jacket can be retract over several millimeters and up to 10 mm. Such a connector is not therefore not suitable for ensuring this recovery over time and in the event of removal of the insulating jacket, removal in itself conventional on this type of cables, an empty space is created which is suitable for breakdowns as was seen above.
L'invention se propose de résoudre ce problème technique et pour ce faire, elle concerne un connecteur de deux câbles d'énergie électrique de moyenne tension, comportant chacun un conducteur entouré d'une enveloppe isolante, connecteur comportant des contacts vissés tubulaires et destiné à connecter ensemble les extrémités mises à nu des conducteurs engagées dans les contacts et maintenues au moyen de vis, connecteur comportant à au moins une de ses extrémités un moyen de prolongement solidaire du connecteur et destiné à couvrir une partie de l'enveloppe isolante du câble, caractérisé en ce que ledit moyen de recouvrement couvre l'enveloppe isolante sur une longueur supérieure à 10 mm.The invention proposes to solve this technical problem and for do this it relates to a connector of two electrical power cables from medium voltage, each comprising a conductor surrounded by a insulating jacket, connector comprising screwed tubular contacts and intended to connect together the exposed ends of the conductors engaged in the contacts and held in place by screws, connector comprising at least one of its ends an extension means integral with the connector and intended to cover part of the insulating envelope cable, characterized in that said covering means covers the insulating jacket over a length of more than 10 mm.
Solidaire du connecteur, le moyen de prolongement est disposé lors de la mise en place du connecteur, sans manipulation supplémentaire.Solid with the connector, the extension means is arranged during the placement of the connector, without additional manipulation.
De préférence, ledit moyen de recouvrement couvre l'enveloppe isolante sur une longueur comprise entre 10 et 20 mm.Preferably, said covering means covers the envelope insulating over a length between 10 and 20 mm.
Selon un mode de réalisation préféré, ledit moyen de prolongement comporte une extrémité libre arrondie.According to a preferred embodiment, said extension means has a rounded free end.
Ce moyen de prolongement fait saillie au-dessus de l'enveloppe isolante du câble ou sur cette enveloppe et forme écran dans cette zone de transition d'extrémité du connecteur, où des champs électriques importants existent, les contraintes électriques locales pouvant entraíner des décharges partielles et des défauts de la connexion. Grâce à son extrémité libre arrondie, l'écran formé assure une bonne distribution des champs électriques.This extension means protrudes above the envelope insulating cable or on this envelope and forms a screen in this area of connector end transition, where large electric fields exist, local electrical constraints can cause discharges partial and connection faults. Thanks to its free end rounded, the formed screen ensures a good distribution of the fields electric.
Selon un premier mode de réalisation, le moyen de prolongement est constitué d'une bride annulaire rigide disposée à la périphérie du connecteur.According to a first embodiment, the extension means is consisting of a rigid annular flange disposed at the periphery of the connector.
De préférence, la bride est une partie intégrante du connecteur.Preferably, the flange is an integral part of the connector.
Selon un second mode de réalisation, le moyen de prolongement est constitué d'une jupe flexible de caoutchouc semi-conducteur fixée à la périphérie du connecteur. According to a second embodiment, the extension means is consisting of a flexible semiconductor rubber skirt attached to the periphery of the connector.
L'invention concerne également une connexion de deux câbles d'énergie électrique de moyenne tension, comportant chacun au moins un conducteur entouré d'une enveloppe isolante, connexion comportant un connecteur tel que précisé ci-dessus et une gaine isolante adaptée pour couvrir intimement au moins le connecteur.The invention also relates to a connection of two cables. medium voltage electrical energy, each comprising at least one conductor surrounded by an insulating envelope, connection comprising a connector as specified above and an insulating sheath suitable for cover at least the connector intimately.
Avantageusement, l'espace entre le connecteur et l'enveloppe isolante du câble correspondant est rempli d'une couche de mastic isolant.Advantageously, the space between the connector and the casing insulation of the corresponding cable is filled with a layer of insulating putty.
Cette couche de mastic isolant est apportée par la gaine isolante pendant sa rétraction et sert à remplir toutes poches d'air restantes.This layer of insulating mastic is provided by the insulating sheath during its retraction and serves to fill any remaining air pockets.
De préférence, l'espace entre la couche de mastic isolant et chaque vis est rempli de mastic conducteur ou d'un capot en matériau semi-conducteur.Preferably, the space between the layer of insulating mastic and each screw is filled with conductive sealant or a cover made of semiconductor material.
