摘要

通过实地考察，发现国产大型汽轮发电机内氢气湿度超标的主要水源来自密封油系统的漏油和窜油，本文着重分析了密封瓦漏油、窜油的主要原因和相应的改进措施，为国产发电机油系统的改进提供了依据。

Abstract

Through on—site investigation in some power plants it is found that the main source of over—limited moisture content of hydrogen inside the large domestic turbogenerators are thc leakage of sealing oil and its diffusion to other channels in hydrogen shaft seals. This paper analyses in detail the main causes of the sealing oil leakage and its diffusion to other channels and proposes improvement measures

thus providing basis to improve oil system for domestic turbogenerators.
