200MW汽轮发电机加装轴向气隙隔板的试验研究

Test and research on adding axial air space diaphragm to 200MW turbine generator

对早期生产的200MW汽轮发电机加装轴向气隙隔板技术进行了试验研究。经多次试验表明，对降低发电机转子绕组的平均温升有显著的效果，从而为国产300—600MW发电机应用这一技术提供了经验。

The paper tested and researched a technology of adding axial air space diaphragm to 200 MW turbine generator made earlier, the tested results showed that the technology can remarkably decrease the average steam temperature of rotor windings, which provides a good reference for using it for from 300 to 600 MW unit.
