摘　　要：氢电导率作为电厂运行监督的一项重要指标之一,是判断凝汽器是否泄漏的重要指标,但凝结水中溶解的二氧化碳含量对氢电导率测量值有很大影响。介绍了脱气氢电导率的原理及其应用现状,对大同二电厂660 MW直接空冷机组凝结水样进行相关试验,分析了测量脱气氢电导率的对直接空冷机组汽水品质监督的重要意义。As an important index,the cation conductivity also is the clue of condenser leakage, however,there will be a great impact on the value of hydrogen conductivity when the water dissolved a lot of Carbon dioxide. This paper introduces degassed cation conductivity and the present situation. On the basis of testing on condensate of 660 MW air cooling unit of Datong No. 2 Power Plant,it analyzed the significance of degassed cation conductivity value to water quality monitoring of direct air cooling unit.
