改用自并激励磁系统的水冷发电机进水装置改造

Retrofit the Water Inlet Devices of Water-cooled Generator Upgraded to Self Shunted Excitation

略阳电厂ＳＱＦ－７５－２型发电机系统将励磁机他励方式改为自并激励磁方式。若取掉励磁机，需对转子进水装置进行改造。根据转子动力学理论，进行了方案比较和选型设计，实施改造后，已投入正常运行。对双水内冷机组的更新改造具有参考价值。

The independent excitation ' pattern of SQF-75-2 type generator system is upgraded to self—shunted excitation in Lueyang Power Plant A retrofit to the rotor water inlet devices is required to remove the exciter Program comparison and configuration design are made based on rotor dynamic theory After retrofit implementation, the unit is put into operation and in good service The can be reference to the retrofit of double—water inner—cooled units
