【摘要】 抽水蓄能机组起动频繁,转子可以正逆两个时针方向转动,绕组绝缘反复经受电磁、热、机械应力的冲击,从而对绝缘系统的可靠性和稳定性提出了比普通水轮发电机更高的要求。本文对发电电动机定子铁心,定子绕组和转子绕组三个部分中相关的绝缘问题展开扼要的说明和分析,总结其绝缘结构设计与制造工艺特点,为今后国内大型发电电动机的绝缘系统优化提供参考依据。更多还原

【Abstract】 The winding insulation of pumped storage generating unit is exposed to repeated impact of electrical,thermal and mechanical stress during the frequent start and stop of the unit with the rotor rotates alternatively in both directions of clockwise and counter-clockwise.Thus the requirement for its reliability and stability is higher than that of usual hydrogenerating units.This paper briefly introduces and analyzes the insulation problem of stator core,stator winding and rotor winding of the generator/motor,summarizes the features of its structural design and manufacturing process.It provides reference for future optimization for the insulation system of large generator/rotor.更多还原
