摘　　要：为了研究水轮发电机升流试验三相电路点的设置位置,以便在设计阶段就综合考虑完善,以利于后期的现场试验。根据发电机出口断路器及主引出线的不同形式,研究了发电机出口三相短路点设置的几种情况。得出结论:在进行电气主接线设计时,应根据不同的接线形式,考虑好三相短路点的设置,在三相短路点与发电机之间布置一组测量电流互感器,以免试验时要另外增加,引起试验的不便。三相短路点的位置应设置在现场便于安装的地方。The study of the setting position of three-phase circuit points for hydrogenerator current boosting test, so as to improve and consider comprehensively in the design stage, benefits the later field test. According to the different types of generator circuit breaker and main lead line, this paper studies several cases of three-phase short-circuit points setting of generator outlet. It is concluded that a set of measuring current transformers is arranged between the three-phase short-circuit point and the generator according to different wiring forms and the setting of three-phase short-circuit points in the design of the main electrical connection scheme, so as to avoid additional increase in the test and cause inconvenience in the test. The location of three-phase short-circuit points should be at a site where it is easy to install.
