摘　　要：氢气冷却汽轮发电机漏氢量(率)的大小直接影响机组的安全运行、影响着发电机的冷却效果、影响着发电机的带负荷能力,这个指标是汽轮发电机运行的主要技术指标之一,所以对发电机组漏氢量(率)的控制很重要。影响发电机漏氢的因素很多,包含发电机密封油系统、发电机氢气冷却系统、发电机定子水冷却系统、发电机本体及与氢气相关的所有结合面、管道、法兰等各方面,本文主要介绍华润电力登封有限公司二期工程2×600MW氢内冷汽轮发电机组氢气冷却器自由端滑动结合面密封漏氢的分析处理,以及处理对发电机漏氢量(率)的影响和处理效果。The hydrogen leakage （rate） of hydrogen cooled turbogenerator directly affects the safety of the unit.. It is one of the major technical indicators of turbogenerator , which influences cooling efficiency and load capability. So it is very important to control hydrogen Leakage （rate） for generator sets. Many factors may lead to hydrogen leakage,such as generator sealing oil system, generator hydrogen cooling system, generator stator water cooling system and all the joint surface, pipes, flanges of the generator body which is hydrogen-related. This paper describes hydrogen leakage processing of the hydrogen cooler free end combined surface ,China Resources Power Dengfeng Co., the second phase of the project 2 ×600MW hydrogen-cooled turbine generator.
