白山电站安装的SF300—48/1230型水轮发电机,定子铁芯外径12300mm,内径11340mm,长度2750mm,是目前国产容量最大的水轮发电机。定子为现场组装。按规程要求,每台机都进行了铁损试验。试验方案基本与《水轮发电机试验》中《铁损试验》一章相同。每台机的试验结果中,单位损耗值都符合厂家要求,绝大多数测点的温升及各点温差,也在规程规定的范围以内,但是,出现了局部温升过高。
Baishan Power Station installed SF300-48 / 1230-type hydro-generator, stator core diameter 12300mm, diameter 11340mm, length 2750mm, is the largest domestically produced hydroelectric generator. The stator is assembled on site. According to the rules and regulations, each machine has carried out iron loss test. The test plan is basically the same as the chapter of “iron loss test” in “Hydraulic Turbine Test”. The test results of each machine, unit loss values are in line with factory requirements, the vast majority of temperature measurement points and the temperature difference between points, but also within the scope of the rules, however, there has been a local temperature rise is too high.
