Abstract

Den foreliggende oppfinnelsen angår en fremgangsmåte for å reparere et viklingssystem i en roterende elektrisk maskin for høyspent, hvilken maskin er designet for direkte tilkopling til et distribusjons- eller overføringsnett og omfatter en stator (20), en rotor og viklinger (30) innbefattet i viklingssystemet. Viklingene (30) omfatter høyspentkabler som i det alt vesentlige inneholder det elektriske feltet i viklingene (30). Fremgangsmåten omfatter trinnet, i tilfelle skade på høyspentkabelen, å skjøte høyspentkabelen på en slik måte at i det minste en del av i det minste en opprinnelig spoleendebøy blir omformet til i det minste et hovedsakelig rettlinjet parti etter skjøtingen, hvor i det minste en skjøt er anordnet utenfor den opprinnelige spoleendebunten, hvilken sammenføyning blir utført uten å demontere den roterende elektriske maskinen.The present invention relates to a method for repairing a winding system in a high voltage rotating electric machine, which 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 which essentially contain the electric field in the windings (30). The method comprises the step, in the event of damage to the high voltage cable, to join the high voltage cable in such a way that at least a portion of at least one original coil end bend is converted into at least a substantially rectilinear portion after the joint, wherein at least one joint is arranged outside the original coil end bundle, which joint is performed without disassembling the rotary electric machine.
