一、概述定子是水轮发电机的主要组成部份,其寿命取决于机组本身的设计是否合理,安装工艺质量的优劣,操作维护是否得当等。对于分瓣定子,大部份工作是在制造厂完成的。如铁芯全部在厂叠压完毕,除合缝线外,其余线卷都在制造厂嵌放并耐压合格。随着单机容量的不断增大,超高超长超重的限制,分瓣定子已远不适应长途运输的要求,而要实行定子散装结构,即把电机制造厂的制造任务转移到电站工地来完成。近年 I. Overview The stator is the main component of the hydroelectric generator, its life depends on the design of the unit itself is reasonable, the quality of the installation process, operation and maintenance are properly. For the split stator, most of the work is done at the factory. If the iron core all in the factory lamination is completed, in addition to the suture line, the remaining coils are embedded in the manufacturer and withstand voltage. With the increasing of stand-alone capacity and ultra-long and overweight limit, the splitter stator is far from meeting the requirements of long-distance transportation. Instead, the stator stator structure is implemented, that is, the manufacturing tasks of the motor manufacturer are transferred to the power station site. in recent years
