俄制TBM-160-2型发电机定子绝缘受潮的分析与处理

ANALYSIS AND TREATMENT OF DAMPNESS IN STATOR INSULATION FOR A RUSSIA-MADE TBM-160-2 TYPE GENERATOR

洛阳热电厂俄制TBM 16 0 2型汽轮发电机组定子绕组绝缘不合格。分析其原因为受潮所致。经采取相应措施后 ,发电机定子三相绕阻交、直流耐压试验一次通过 ,发电机在各种工况下运行良好。

The stator winding insulation of a Russia-made TBM-160-z type turbine-generator at Luoyang Thermal Power Plant wasn't up to standard due to being affected with dampness. A scheme of solution was worked out after analysis. Through treatment, the AC and DC voltage endurance tests on three phase stator windings of the said generator have been passed on their first run, making the said generator to operate well under various working conditions.
