发电机定子冷却水系统在电厂中处于重要的地位,它保证了发电机在正常运行功率下的最大连续输出。在这个输出功率下,定子冷却水系统可以从定子绕组和端子带走热量,并把热量散到常规岛闭式循环冷却水系统。介绍了福清核电3号机组定子冷却水系统的功能,分析了其初步运行试验内容及问题,以期为发电机组长期稳定运行提供保障。
Generator stator cooling water system in the power plant is in an important position, it ensures that the generator at normal operating power under the maximum continuous output. At this output, the stator cooling water system removes heat from the stator windings and terminals and dissipates the heat to the conventional island closed-circuit cooling water system. The function of the stator cooling water system of Fuqing NPP Unit 3 is introduced. The contents and problems of the preliminary operation test are analyzed in order to provide guarantee for the long - term stable operation of generating units.
