双流环密封油系统发电机进油原因分析及处理

Reasons Analysis and Treatment of Generator Oil Intake in Double-flow Ring Sealing Oil System

发电机密封油系统是氢冷发电机的重要组成系统,可以有效地对发电机内部氢气进行密封并且对密封瓦起到润滑和冷却作用,但好多电厂均出现不同程度的发电机进油现象,从密封油系统和发电机的结构特点出发,通过现场参数调整和一些针对性措施对发电机进油问题进行处理,确保发电机安全稳定运行。

Generator sealing oil system is an important component of hydrogen-cooled generator system, which can effectively seal hydrogen inside the generator and lubricate and cool the sealing bush. But many power plants have different degrees of generator oil intake. Starting from the structural characteristics of sealing oil system and generator, this paper adjusted on-site parameters and took some targeted measures, to ensure the safe and stable operation of the generator.
