摘要
在相复励旋硅式无刷同步励磁电机中,如果在正常运行过程中出现硅整流管开路或短路的故障,必将危及到发电机组的运行。本文提出了一种在线监测旋转硅整流管的方法和设计出监测电路,当硅整流管开路时能发出信号,在短路时能迅速解列发电机,以维护机组的安全。
In the rotating-diode phase compound excitation Brushless synchronous machine, if one diode appears fault, such as opening or shorting during the normal operating, it will do harm to the generator, The design of this model give one way to monitor the rotating-diode, which gives a sign for opening diode or makes the generator trip for shorting diode, and protects the machinei＇s safety.
