Analysis and treatment for anomaly of direct-current leakage of generator stator winding caused by hydrogen cooler fault 氢气冷却器故障使发电机定子绕组直流泄漏异常的分析与处理
This system can print performance of direct-current generator relative factually and make testing results convenient for consulting at any moment. 对性能建立数据库,使测试结果能随时查阅,并能打印出性能曲线及测试数据报表。
It is described that new installations such as variable speed water pump with direct-current generator, large observing-windows with sealed entrance gate, manhole and water-spray mist-remover all have operated efficiently. 还对直流电机无级变速拖动水泵,大型观测窗,大型密封门,快速人孔和喷水除雾刷等新技术,在运行应用上取得较好效果。
The direct-current leakage test is implemented by using the microampere shielded in low-voltage, and the leakage current increasing of generator stator winding abnormally is detected. 采用低压屏蔽法对发电机定子绕组进行直流泄漏试验,发现泄漏电流异常增大。
