摘　　要：介绍了一种灭磁回路跨接器的新型检测方法:根据发电机转子的电感特性,功率整流桥输出电压的负半波可模拟成转子反相电压,对跨接器的功能进行检测。现场实际应用表明,该方法可保证相关灭磁回路的可靠性,最大限度减少灭磁回路故障导致的发电机组灭磁事故。This paper introduced a new detection method for deexcitation circuit jumper function test using rotor reverse voltage,which could be simulated from the negative half cycle of power rectifier bridge output voltage according to the inductance characteristics of generator rotor. Field application indicated that this method could ensure the reliability of related de-excitation circuit and reduce the de-excitation accidents of power unit due to faults of de-excitation circuit to the most extent.
