国产QFSN-600-2YHG型汽轮发电机漏氢原因分析及处理

Analysis and treatment to the hydrogen gas leak in the QFSN-600-2 YHG Turbonator

氢系统对于发电机的安全运行起到了关键的作用.介绍了庄河发电公司QFSN-600-2YHG型汽轮发电机组,在运行中发现严重漏氢现象,叙述了对氢系统进行全面检查的过程,及漏点的处理工艺和原因分析.实践表明:采用标准的工艺流程对机组漏氢进行检修,可得到满意的效果.

This paper mainly introduces the serious hydrogen gas leak in the QFSN-600-2 YHG turbonator of the Chuang river generate company. The QFSN-600-2 YHG turbonator has whole sealing structure to realize internal hydrogen circulation, and its stator winding adopts water inner-cooling while the core, the stator ends and the rotor winding adopt hydrogen cooling. During the serving, hydrogen gas leak is very serious. Through the overall checking to the hydrogen system, this paper gives the reason and treatment to the leak source.
