发电机转子绕组短路检测方法

The Detection of Short Circuit of Generator Rotor Windings

通过对发电机转子绕组匝间短路、绕组接地故障的分析,提出了利用传统的交流阻抗、直流电阻测量,结合转子极电压平衡和绕组频谱特性曲线测试,检测发电机转子故障的新方法。

Based on the analysis of generator rotor winding faults such as inter-turn short circuit and abnormal earthing, a new method,which utilizes the traditional technique to measure alternating impedance and D.C. resistance, combining to measure rotor pole balance and rotor winding frequency characteristics, has been presented to detect rotor faults.
