| 摘要: |
| 提出一种新型磁控式故障限流器，它由电流源提供直流电流，并采用晶闸管导通切断直流电流。阐述了新型磁控式故障限流器的基本工作原理与基本结构。设计了一台220 V的新型磁控式故障限流器实验样机，对样机的性能进行了测试。测试结果表明：电力系统正常运行时，磁控式故障限流器对电力系统正常输电能力影响较小；电力系统发生短路故障时，磁控式故障限流器可以用20 ms左右的时间把短路电流减小至危害较小的程度。 |

| Abstract: |
| A magnetic-control-type FCL（Fault Current Limiter） is proposed，which supplies DC from the current source and cuts off it by switching on the thyristor. Its basic operational principle and configuration are introduced. A 220 V prototype is designed and its performance is tested. The test results show that，it has little influence on the transmission capacity of power grid in normal operating conditions while it diminishes the fault current to a less harmful level within about 20 ms during the short circuit fault of power grid. |
