摘要
Abstract
No.6 generator of Yunnan Dachaoshan Hydropower Station has been in operation for nearly 20 years and underwent A-level maintenance of the unit in February 2023.In the preventive test of the generator,a large number of corona points were found using ultraviolet equipment.The plan is to repair the stator corona during the maintenance period,improve the insulation level of the generator stator,and increase its service life.After treatment,the overall insulation level of the generator stator has been improved,effectively curbing the spread of corona and providing assurance for the safe and stable operation of the unit.关键词
