摘　　要：国家能源局《防止电力生产事故二十五项重点要求》第10.5.2条明确规定发电机内冷水箱中含氢(体积含量)超过2%应加强对发电机的监视,超过10%应立即停机消缺。内冷水系统漏氢量达到0.3m3/d时,应计划消缺,漏氢量大于5m3/d时,应该立即停机处理。多年以来缺乏一种能够准确、快速有效的监测方法。Article 10.5.2 of the 25 key requirements for the prevention of power production accidents issued by the national energy administration clearly stipulates that if the hydrogen(volume content)in the cooling water tank of the generator exceeds 2%,the monitoring of the generator shall be strengthened,and if it exceeds 10%,the generator shall be shut down immediately for defect elimination.When the hydrogen leakage of internal cooling water system reaches 0.3m3/d,it shall be eliminated.When the hydrogen leakage is greater than 5M3/D,it shall be shut down immediately for treatment.For many years,there has been a lack of an accurate,rapid and effective monitoring method。
