Abstract

L'invention concerne un conducteur de transport d'énergie électrique aérien haute tension comportant un groupe central (1) comprenant dans au moins une couche interne des fils tubulaires métalliques (1A) autour d'un jonc central (1B), ce groupe central (1) étant entouré d'au moins une couche externe de fils pleins conducteurs (2).Selon l'invention, ladite couche interne comprend également au moins un fil plein (1D).

Description

  • L'invention concerne un conducteur de transport d'énergie électrique aérien haute tension.
  • Le document de brevet CN 203520993 décrit un conducteur de transport d'énergie électrique aérien haute tension comportant un groupe central de tubes en aluminium toronnés entouré de couches de fils conducteurs pleins en aluminium également toronnés.
  • Si ce groupe central de tubes en aluminium permet d'obtenir un conducteur de diamètre relativement important et donc d'éviter l'effet couronne appelé également effet corona propre à générer un bruit audible, lorsque ce conducteur est installé et sous tension, ce type de conducteur pose le problème technique suivant.
  • Ce conducteur connu présente une tenue au sertissage de manchons de connexion très limitée, les tubes du groupe central ayant une forte tendance à se déformer.
  • L'invention résout ce problème en proposant un conducteur de transport d'énergie électrique aérien haute tension présentant une résistance transversale assurant une bonne tenue au sertissage de manchons de connexion.
  • L'invention concerne un conducteur de transport d'énergie électrique aérien haute tension comportant un groupe central comprenant dans au moins une couche interne des fils tubulaires métalliques autour d'un jonc central, ce groupe central étant entouré d'au moins une couche externe de fils pleins conducteurs, caractérisé en ce que ladite couche interne comprend également au moins un fil plein.
  • Grâce à l'invention, le diamètre du conducteur est augmenté sans augmentation notable de son poids, ce qui est important, car ce type de conducteur aérien est installé sur des pylônes et le renfort mécanique de ces pylônes est complexe et coûteux.
  • L'invention permet également d'obtenir un conducteur pouvant travailler à haute température et garantissant une bonne durée de vie.
  • Selon un mode de réalisation préféré, ladite couche interne comporte au moins deux fils pleins.
  • Lesdits deux fils pleins sont de préférence diamétralement opposés dans ladite couche interne.
  • De préférence, le(s)dit(s) fil(s) plein(s) est (sont) de même diamètre externe que lesdits fils tubulaires.
  • Avantageusement, le(s)dit(s) fil(s) plein(s) est (sont) métalliques.
  • De préférence, lesdits fils sont en aluminium ou alliage d'aluminium. L'aluminium peut être dur ou recuit.
  • Ledit jonc central est de préférence constitué de fibres noyées dans une résine.
  • Le conducteur présente grâce à ce type de jonc composite une tenue mécanique particulièrement importante, permettant une installation sur des pylônes relativement éloignés.
  • Le jonc central peut être également un jonc en fils d'acier ou en fils d'aluminium ou d'alliage d'aluminium.
  • Ledit jonc central est avantageusement constitué de fibres de carbone noyées dans une résine époxy.
  • Ledit jonc comporte avantageusement une couche de revêtement d'aluminium ou alliage d'aluminium.
  • De préférence, les fils conducteurs de ladite couche externe sont de diamètre inférieur à celui des fils de ladite couche interne. En effet, la réduction du diamètre des fils de la couche externe par rapport au diamètre des fils de la couche interne permet de réduire le bruit engendré par l'effet de couronne, émis par la ligne en fonctionnement, en limitant l'effet de pointe à l'origine de l'ionisation de l'air et du bruit.
  • Lesdits fils sont de préférence toronnés.
  • L'invention est décrite ci-après plus en détail à l'aide d'une figure ne représentant qu'un mode de réalisation préféré de l'invention
  • La figure unique est une vue en coupe transversale d'un conducteur de transport d'énergie électrique aérien haute tension conforme à l'invention.
  • Un conducteur de transport d'énergie électrique aérien haute tension conforme à l'invention comporte un groupe central 1 comprenant dans une ou plusieurs couche(s) interne(s) des fils tubulaires métalliques 1A, de préférence en aluminium ou alliage d'aluminium, et également au moins un fil plein 1D de même diamètre externe, autour d'un jonc central 1B et ce groupe central est entouré d'au moins une couche externe de fils pleins conducteurs 2, de préférence en aluminium ou alliage d'aluminium.
  • Selon ce mode de réalisation préféré, la couche interne comporte au moins deux fils pleins 2A métalliques, et de préférence en aluminium ou alliage d'aluminium, diamétralement opposés dans la couche interne. Il est ainsi obtenu une bonne résistance à la compression transversale.
  • Tous les fils sont toronnés pour former le conducteur.
  • Le jonc central 1B est constitué de fibres de carbone noyées, de préférence par pultrusion, dans une résine époxy et comporte une couche d'aluminium 1E de revêtement d'aluminium ou alliage d'aluminium.
  • Les fils conducteurs 2 de la couche externe sont de diamètre inférieur à celui des fils 1A, 1D de la couche interne.
  • A titre d'exemple dimensionnel, un tel conducteur peut comprendre :
    • un jonc central 1B composite d'un diamètre de l'ordre de 7 millimètres avec une couche de revêtement 1E d'une épaisseur de l'ordre de 0,5 millimètre,
    • six fils tubulaires 1A de la couche interne, d'un diamètre de l'ordre de 5 millimètres et d'une épaisseur de l'ordre de 1,5 millimètre,
    • deux fils pleins 1D de la couche interne d'un diamètre de l'ordre de 5 millimètres,
    • dix-huit fils conducteurs 2 de la couche externe d'un diamètre de l'ordre de 3,5 millimètres.
