摘要
某厂超临界600 MW定子绕组水内冷发电机在投产3年后,定子上下层线棒槽层间温差逐渐升高,发电机定子线棒进、出水差压高达340 kPa,详细介绍了采用碱洗+酸洗+漂洗钝化的复合清洗工艺。经化学清洗后,定子上下层线棒槽层间温差趋于正常,发电机定子线棒进、出水差压下降至合理值,保证了发电机的安全运行。
Factory 600 MW supercritical water cooled generator stator windings after 3 years in operation, The stator slot bar on the lower layer gradually increased temperature difference between, Into the generator stator bar, the water pressure up to 340 kPa. Described in detail by Caustic ＋ acid ＋ cleaning process rinse passivation compound.
