摘　　要：仙衣滩电厂机组运行中,特别是在夏天外界环境温度较高时,存在温度偏高的现象,为了保证机组的安全运行,运行人员不得不降低出力运行,从而大大降低了电站的发电效益和机组运行的安全性;且灯泡头和定转子运行温度高,巡视人员的工作环境也较差。通过对仙衣滩电厂机组冷却系统冷却过程存在问题的研究分析,利用夏季、冬季不同实测温度对比,提出新增板式冷却器冷却功率及配套实施方案,达到降低发电机定子、轴承瓦温度的效果。when the environment temperature is high especially in the summer, problems in the operation of the Xianyitan power plant unit will appear. In order to ensure the safe operation of the unit, operators have to reduce output, so as to greatly reduce the efficiency of the unit and the safety of the unit operation. Through the Xianyitan power plant secondary cooling system research and analysis of problems in heat transfer process, using different measured temperature in summer and winter, the new plate cooler cooling power is put forward and a complete set of implementation plan is formed, to reduce the generator stator and bearing bushing temperature effect.
