本文介绍 ABB 公司大型水轮发电机中的斜构件结构,包括上下机架采用斜支臂、定子机座上下端的斜脚板和转子支架用斜支板。斜构件结构使发电机受力好,减小了热应力以及铁心对基础上的转矩作用力,对发电机运行十分有利。 This article introduces the structure of diagonal components in ABB’s large hydroelectric generator, including the upper and lower racks with inclined arm, the upper and lower slanting legs of the stator frame and the inclined support plate for rotor support. The structure of the diagonal member enables the generator to exert a good force, which reduces the thermal stress and the torque acting on the base of the iron core, which is very beneficial to the generator operation.
