摘要
对丹东电厂2号发电机氢气湿度超标的特点、东港地区空气湿度的走势进行了分析,探讨了环境湿度影响发电机氢气湿度的机理。2号发电机氢气湿度主要是在夏季超标,东港地区湿度的季节性与2号发电机氢气湿度趋势相吻合,其湿度超标是发电机氢气系统不严密、空气漏入所致。
This paper analyzes the characteristics of excess hydrogen humidity for generator and the trend of air humidity in Donggang area. It explores the mechanism generator hydrogen humidity is affected by the environment humidity. It approves that excess hydrogen humidity for No. 2 generator generally occurs in summer, and the change of hydrogen humidity for NO. 2 generator is related to the seasonal change of air humidity in Donggang area. It comes to the conclusion that air leakage and poor seal in generator hydrogen sys- tem causes excess hydrogen humidity.
