摘　　要：介绍了国内1000MW核电站氢冷发电机使用的2种密封油系统的功能、结构和特点,并进行综合分析比较,指出单流环密封结构简单,又具有油、水分离装置,运行安全可靠;双流环密封结构复杂,但运行比较灵活。从发展的观点来看,单流环密封具有替代双流环密封的趋势。An introduction is being presented to the function, structure and features of 2 sealing oil systems for hydrogen-cooled generators of domestic 1 000 MW nuclear power stations. By comparing the 2 sealing structures, it is found that the single-flow sealing structure has advantages of more simple construction, higher safety and reliable operation performance, and with oil/water separation device, while the double-flow sealing structure is featured by complicated construction, but facile operation. From the point of view of development, there is a tendency that the double-flow sealing structure is going to be replaced by the single-flow one.
