摘要
发电机漏氢是汽轮发电机组安装中比较普遍的质量问题。通过分析以往造成发电机漏氢的各方面原因,在华润首阳山电厂2号发电机施工中采取了相应的控制措施,在168h运行期间经过实测,2号发电机漏氢量在5.5m3/d,远小于厂家安装说明书要求的氢气耗量13～19m3/d,最终证明所采取的控制措施是有效的。
Hydrogen leaking is a common quality problem in turbine-generator unit installation. By analyzing the causes for past generator hydrogen leakage, corresponding countermeasures were taken in the construction of No. 2 generator of Huarun Shouyangshan Power Plant. During the 168 h operation, the measured hydrogen leakage from No. 2 generator was 5.5 Nm^3/d, which is far less than the manufacturer specified 13-19 m^3/d. It proves that the countermeasures are effective.
