摘　　要：某电厂#2机定冷水箱内氢气浓度超标,严重影响机组的安全稳定运行。通过采取对定冷水箱连续充氮、更换发电机氢-水压差低开关等措施,将定冷水箱内氢气浓度控制在了安全范围内。文章通过对#2机定冷水箱氢气浓度异常现象的出现、采取的措施和相关运行参数的变化情况进行分析总结,为今后定冷水系统的运行监督提供经验借鉴。The hydrogen concentration in the cooling water tank of Unit#2 in our factory exceeds the standard,seriously affecting the safe and stable operation of the unit.By taking measures such as continuously filling nitrogen into the cooling water tank and replacing the low hydrogen water pressure differential switch of the generator,the hydrogen concentration in the cooling water tank is controlled within a safe range.This article aims to analyze and summarize the occurrence of abnormal hydrogen concentration in the cooling water tank of Unit#2,the measures taken,and the changes in relevant operating parameters,in order to provide experience and reference for the operation supervision of the cooling water system in the future.
