The invention discloses a local replacement process method for an upper-layer wire rod of a stator of a large-scale gas turbine generator. The new process method for dismantling the single stator bar on the upper layer and the lower layer of the large-scale gas turbine generator is adopted, and the number of the required door-opening bars is determined by performing a process test on the old bars, so that the new stator bar is safely and effectively replaced, and the local replacement of the upper layer of the stator bar becomes possible. By adopting the new process method for local replacement of the stator winding, the upper-layer stator bar of the large-scale gas turbine generator can be removed to the minimum extent, the safety of the adjacent stator bars is ensured, the construction period and the huge cost are saved, and the economic and social significance is great. Meanwhile, the blank of local repair in China of the gas turbine generator is made up. |
