摘　　要：从发电机转子水冷系统设计、安装和运行维护入手,详细分析了嵩屿电厂二期300 MW双水内冷发电机转子出水支座甩水原因,认为主要由于出水支座内水位太高和风压过大、转子卸水槽错位造成。对此,提出了改进方案,实施后彻底消除了甩水现象。starting with the system design, equipment installation, and maintenance in operation of the water cooling rotor in generator, the causes leading to water throw- off from water - discharging susupport of the rotor in dual internal water cooling 300 MW generator in secondary - phase project of Songyu Power Plant have been analysed in detail. After suggesting and implementing the improvement scheme, the water throw- off phenomenon has been thoroughly eliminated.
