大中型水轮发电机的定子，因外形尺寸大，受到运输条件的限制，其定子机座采用分瓣制造运输，在安装现场进行组装焊接、铁芯堆积及定子下线。定子铁损试验是在定子铁芯冲片叠装、压紧后进行，通过测量铁损、温升及温差的方法检查定子铁芯冲片的制造及叠装整体质量，定子铁芯制造及安装质量好坏关系着机组的长期安全运行。文章对弄令电站1＃发电机定子铁损试验的实施进行了研究分析。
大中型水輪髮電機的定子，因外形呎吋大，受到運輸條件的限製，其定子機座採用分瓣製造運輸，在安裝現場進行組裝銲接、鐵芯堆積及定子下線。定子鐵損試驗是在定子鐵芯遲片疊裝、壓緊後進行，通過測量鐵損、溫升及溫差的方法檢查定子鐵芯遲片的製造及疊裝整體質量，定子鐵芯製造及安裝質量好壞關繫著機組的長期安全運行。文章對弄令電站1＃髮電機定子鐵損試驗的實施進行瞭研究分析。

Abts ract:Large and medium-sized hydro-generator stator,because of large dimensions,the restriction of the transportation conditions,the stator frame is manufactured and transported in split parte,installing, assembly welding,iron accumulation and stator winding on site.The stator iron loss test is in the stator iron core punching sheet stacking, pressing.By measuring the iron loss, temperature rise and the temperature difference,manufacturing and stacking the overall quality of the stator iron core punching sheet is inspected.The stator core manufacturing and installation quality is of significance for long-term safe operation of the unit.This paper carried on the research and analysis for 1#generator stator iron loss test in Nongling Hydropower Station.
