摘要
针对空载合闸变压器励磁涌流在电力系统中产生的危害,提出了一种新的削弱励磁涌流的方法,利用ATP-EMTP详细分析了ZnO避雷器式故障限流器对励磁涌流的影响,通过四种方式对空载时的励磁涌流进行了对比,结果表明:ZnO避雷器式故障限流器对变压器励磁涌流有良好的抑制作用。
With regard to the harms of magnetizing inrush current caused by transformer energizing in electrical system, a new method to reduce magnetizing inrush current is presented. This paper analyzes the impact of ZnO surge arrester （MOA） based fault current limiter （FCL） on transformer magnetizing inrush current by ATP-EMTP and compares the impact on magnetizing inrush current in four ways. The results show that MOA-based FCL can effectively reduce transformer magnetizing inrush current.
