摘　　要：氢冷发电机中,氢气品质降低会给发电机组带来一系列的安全、经济问题。基于常用的单流环、双环流密封油系统结构特点,分析两种形式的密封油系统差异及其对氢气纯度的不同影响,并提出了针对性改进措施,对于稳定氢冷发电机氢气纯度有一定帮助。In a hydrogen cooled generator, the reduction of hydrogen quality would bring about a series of safety and economic problems. Based on the structural characteristics of common single-ring and double-ring seal oil systems, analyses are carried out concerning the differential comparison of two types of seal oil systems and their different effects on hydrogen purity, and the corresponding preventive measures are put forward, which is regarded as a certain reference for maintaining the stability of hydrogen purity for hydrogen-cooled generators.

关 键 词：氢冷发电机 密封油系统 氢气纯度 密封油质量
