一起发电机定冷水系统故障处理及原因分析

Cause analysis and treatment of a fault of generator stator water-cooling system

针对一起300 MW水氢氢冷汽轮发电机定冷水系统所出现的故障,通过对发电机定冷水系统结构的分析,对引起发电机定冷水含氢气的各种原因进行了深入的探讨,提出了在定冷水系统运行、检修过程中的一些注意事项,为同类型发电机定冷水系统的运行、检修提供了解决办法和参考。

Treatment on stator water cooling system fault of a 300MW water hydrogen inner-cooler turbogenerator was illustrated. Furthermore, the paper introduced the structure of generator stator water cooling system and discussed reasons caused hydrogen in generator. Finally, the notice should be pay attention to in operation and maintenace was put forward providing solutions and reference to same tpye system.
