摘　　要：为解决海上采油平台大型进口发电机组主要部件损坏后出现的严重故障,对其进行国产化翻新意义重大。概括了海上油气平台进口主发电机转子匝间短路的表现形式和诊断方法,初步探讨了发电机转子新线圈的选择和绕制等国产化步骤,阐述了使用新转子后发电机的动平衡调整过程,明显降低了发电机运行振动。研究结果表明,该研究为深入实施进口发电机国产化奠定了基础。For resolving the serious failure due to the damage of main parts in the large imported generating units on the offshore oil platform, the localization refurbishment of the parts is significant. The form and diagnostic method of turn-to-turn short circuit on the imported main generator rotor of the offshore oil gas platform were generalized , the localization steps of the choice and winding for generator rotor new coil were explored preliminary, the generator dynamic balance adjustment process was illustrated after using the new rotor, and the generators running vibrations was obviously decreased. The results show that the research lays a foundation for the deep implementation of imported generator localization.
