摘要
通过对某公司#1发电机发生误强励前后发电机空载特性参数及转子绕组的交流阻抗和功率损耗等测试数据分析,论述了强励电流冲击对发电机转子绕组的影响以及机组异常振动与发电机转子绕组匝间短路的关系,并提出相应的防范措施。
This article discusses the influence of generator rotor windings under strong exciting current shock and the relationship between abnormal vibration of generator and short circuit of generator rotor windings. Based on analysis be-fore-and-after the generator have some mal-excitations with some test data like no-load characteristic parameters and gen-erator rotor windings’ AC Impedance and power loss. And then put forward the corresponding precautions.
