The present invention relates to a method of repairing a winding system in a rotary electric machine for high voltages, which machine is designed for direct connection to a distribution or transmission network and comprises a stator (20), a rotor and windings (30) included in the winding system. The windings (30) comprise high-voltage cables that substantially contain the electric field in the windings (30). The method comprises the step of, in the event of damage to the high-voltage cable, splicing the high-voltage cable in such a manner that at least one part of at least one original coil-end bend is converted to at least one substantially straight portion after the splicing, wherein at least one join is arranged outside the original coil-end bundle, which splicing is performed without dismantling the rotary electric machine.
L'invention concerne un procédé de réparation d'un système d'enroulement dans une machine électrique tournante à haute tension, laquelle est conçue pour être connectée directement à un réseau de distribution ou de transmission et comporte un stator (20), un rotor et des enroulements (30) intégrés au système d'enroulement. Les enroulements (30) comprennent des câbles haute tension qui maintiennent sensiblement le champ électrique dans les enroulements (30). Ledit procédé consiste, en cas d'endommagement du câble haute tension, à épisser le câble haute tension de sorte qu'au moins une partie d'au moins un coude de la tête de bobine d'origine soit converti en au moins une partie sensiblement droite après l'épissage, au moins un joint étant placé à l'extérieur du faisceau de la tête de bobine d'origine, l'épissage s'effectuant sans démontage de la machine électrique tournante.
