摘　　要：上桥泵站改造工程的三台立式同步电动机在空载试验中开机30min后,定子温度急剧升高,高出环境温度85°并仍上升不止。文章对温升偏高的原因作定性分析,提出处理方案及施工方法。处理后现场负载试验数据符合国家有关标准。In the noload test of three vertical synchro nous motors installed in the Shangqiao Pumping Station, the temperature of the stator rose rapidly in 30 rain to reach 85° , higher than that of ambient and still continued to rise. The reason of the high temperaturerise was analyzed while the treatment and processing method were worked out. The final field test and load test data met with those specified in the National Standard.
