发电机转子

• During its operation , the rotor of the machine is always under the great suppression of centrifugal force . the surface of rotor is the most important part to enduring the forces and thermal energy . so the windings of rotor are in a common problem of happening one - point to earth short fault , two - point to earth short fault , or turn - to - turn short fault
  汽轮发电机是一种高速隐极式同步电机，在其运行时，转子受到强大的离心力的作用，而转子表面是承受机械应力和发热的最关键的部件，因此汽轮发电机转子绕组容易发生一点接地、匝间短路和两点接地短路故障。
