不饱和聚酯玻璃纤维增强模塑料在发电机中的应用优化

Application Design Optimization of Dough Molding Compound(DMC) in Generator

大型汽轮发电机定子绕组端部振动是设计、制造和运行中不可忽略的问题,抑制汽轮发电机定子绕组端部振动的方法就是加强绕组端部固定。国内厂家从2005年开始使用新型热固性材料——不饱和聚酯玻璃纤维增强模塑料DMC,来解决大型汽轮发电机定子下线过程中线棒端部渐开线与端部绑环配合紧密问题。本文着重介绍DMC用于汽轮发电机定子绕组端部固定的情况,以及为满足生产需要而对DMC进行的固化工艺优化。

The Vibration of stator end winding is a problem that can not be ignored in designing and manufacturing and operation of large capacity tarbine generators.Method to restrain vibration of turbine generator stator end winding is strengthening the fixture of end winding.Since 2005,some domestic manufacturers began to use Dough molding compound（DMC） to solve the problem of fit dimensions between stator end windings and end support rings.This paper mainly introduces the Dough molding compound（DMC）which is used in turbine generators to fix the stator end winding,and the optimization of curing process to meet the manufacturing requirements.
