摘要
介绍了大型船舶发电机转子线圈匝间短路故障时的机械特性和电磁特性,总结出了转子匝间短路时电磁电流和无功功率的变化规律,进而提出分析和诊断匝间短路故障的方法。
The paper analyses the mechanical and electric magnetic features on interturn short circuit in the larger shipping- generator rotor.And summarizes the regularity that the chang of output reactive power and exciting current,the anthors raise the method for fault analysis and diagnosis of Interturn in the larger shipping-generator rotor.
