摘　　要：分析了汽轮发电机传统的密封油系统转动设备多,运行不可靠,检修维护费用高的原因;提出了一种新的密封油供油方式,实行空、氢侧联合运行。改进的方案系统变动小,投资少,收效明显。High maintenance costs are generally required by oil sealing systems of conventional turbine generator units, because too many rotary equipment are included, which are easy to make operation unreliable. A new sealing oil supply way is being presented which applies combined cycle mode at both air and hydrogen side. The improved system has only small changes, with little investment, but obvious effects.
