摘　　要：目前国内汽轮发电机转子一般采用间苯二酚与聚芳纤维纸聚酰亚胺薄膜复合材料(NHN)热压而成的"U"形槽绝缘,这种槽绝缘的力学性能不高,并且制造工艺及所需模具都比较复杂。而国外一些发电机生产厂家采用了环氧树脂浸渍玻璃坯布和聚芳酰胺纤维纸(Nomex)热压而成的新型"L"形复合槽绝缘。本文就是对这种使用方便、性能优良的环氧型槽绝缘进行结构研究和性能分析,为今后国内大型火电发电机转子槽绝缘结构的设计提供参考。Slot armor for turbine generator rotor in our country is generally resorcin-NHN construction with ＂U＂shape. The manufacture process and the mold used for this structure is complexed. Now, a new type of slot insulation has been adopted by some nanufacturer abroad. It is epoxy glass cloth-Nomex construction with ＂L＂shape. This paper mainly analyzes its structure feature to give reference for design of turbine generator rotor slot armor in our country.
