【摘要】 巨型水轮发电机一般额定转速较低,转动部分的重量和结构尺寸较大,因此发电机结构选型和设计工作非常重要。本文介绍了立轴半伞式密闭自循环全空冷三相凸极同步巨型水轮发电机结构特点,主要包括巨型水轮发电机定子、转子、推力轴承和下导轴承、下机架、轴承冷却系统等。对巨型水轮发电机的设计具有一定指导意义。更多还原

【Abstract】 Normally, the huge hydro-generator has heavy rotating components, large structural dimension and low rated speed, so the type selection and structure design is very important. This paper presents the design features of vertical shaft semi-umbrella type enclosed self-circulating totally air-cooled three-phase salient-pole synchronous huge hydro-generator, including stator, rotor, thrust bearing and guide bearing, lower bracket, bearing cooling system and so on. It is useful for guidance of the huge hydro-generator design.更多还原
