摘　　要：双绕组交流励磁机是在同一个电枢铁心内设置两套星型连接的绕组,两套星型连接的绕组感应出三相交流电后通过旋转的三相桥式整流器整流后为同轴安装的两个同步发电机提供励磁电压、励磁电流。当任意一个同步发电机负载发生扰动,该励磁机对应绕组能相应的做出补偿,而对另一同步发电机没有任何影响,即互不干扰。The double winding AC exciter is two sets of windings of star connection are set in the same armature core.The windings of the two star-connected windings are induced to produce three-phase alternating current and then rectified by a rotating three-phase bridge rectifier to provide excitation voltage and excitation current for the two coaxial synchronous generators.When the load of any synchronous generator is disturbed,the corresponding windings of the exciter can compensate accordingly,without any influence on the other synchronous generator,it’s called non-interference.
