摘要
分析了相复励旋硅式无刷同步励磁电机旋转二极管的开路和短路状态 ,并以某大功率中速柴油发电机组为例 ,分析了其旋转二极管监测电路框图的工作原理 ,该监测电路在二极管开路时能延时发出信号 ,而在二极管短路时能迅速解列发电机 ,以维护机组的安全。
In this paper, both open and short circuit of the rotating diodes in brushless synchronous excitation machines with rotating diode phase compound excitation are is analyzed in detail. The diesel generation unit of my company is selected to study. The principle of its rotating diodes monitoring circuit is investigated. The diode in the monitoring circuit can send a delayed signal when open, and disconnect the generator from system at once for protection when short. The performance of the monitoring circuit is illuminated and discussed briefly at the end of this paper.
