为了确定原60周率发电机改为50周率运行后各量的变化,以及选择合理的运行方式,在某3000瓩改周率发电机进行了较详细的比较试验,以供其他改周率发电机选择运行方式的参考,对於已改为50周运行发电机可以不再进行60周的各种试验。 一、发电机情况的简述 该发电机为德国AEG厂於1920年以前制造名牌为:周率60周、转速3600转/分、电压2300伏、电流1087安、力率0.7、转 In order to determine the changes in the quantity of generators after the original 60-week-rate generator was changed to 50 cycles and to select a reasonable mode of operation, a more detailed comparison test was conducted on a 3000-period alternator generator for other weeks. The reference for the mode of operation of the alternator is selected and the generator can no longer be tested for 60 weeks for generators that have been changed to 50 weeks. I. Brief description of the generator The generator was a German AEG factory manufacturing brand name before 1920: weekly 60 weeks, speed 3600 rev / min, voltage 2300 volts, current 1087 amps, power rate 0.7, turn
