300MW发电机出线套管漏氢的根治

Resolusion of H_2 Leakage from the Outlet Lead Sleeve of the 300MW Generator

氢冷发电机漏氢是影响机组安全运行的重大隐患,出线套管部位的漏氢缺陷很难提前发现,而一旦有此类故障就会引发恶性事故。因此,采取措施彻底根治出线套管部位漏氢缺陷是发电厂急需解决的技术问题。

H2 leakage of the hydrogen-cooled generator was one of the most important hidden troubles to influence the safe operation of the generator set. Once this hidden trouble existed, the malign accident would take place. It was the key technical problem for the power plant to take means to resolve the H2 leakage from the outlet lead sleeve.
