摘　　要：阐述了某重型机械厂真空超速室发电机增容改造技术。主要介绍了电磁设计中斜槽铁心、变断面电枢绕组的选用、每槽2片全节距异槽式单迭绕组的优点等;结构设计中转子支架轴结构、电枢迭片铁心特点、主换向极铁心及线圈结构特点等。简单介绍了换向器结构、刷杆座圈结构以及VPI绝缘工艺。This paper describes an uprating modification technology adopting in the generator of Beizhong vacuum overspeed room. The electromagnetic design is chiefly introduced in aspects of application of skewed-slot core, selection of variable crosssection armature windings and advantages of 2 full-pitch different-slot single-lap windings per slot. The structural design is also described in aspects of structure of rotor shaft with supporting frame, features of armature lamination core and structural characteristics of core and coils in main commutating pole. The structures of commutator, brushholder stud and base ring and VPI insulation technology are briefly introduced.
