摘要(Abstract)：

通过相量图分析各类典型故障后电流电压的变化,对500 kV主变低压侧干式电抗器开关及流变位于中性点侧接线方式下的保护方式进行了讨论。通过分析近年来电抗器发生的故障,并结合实际运行情况,积极探讨保护的最佳配置方式。
Through the analysis of the variations of current and voltage after various typical faults on the basis of phasor diagram,this paper discusses the protection method for neutral point side connection mode of switch and current transformer of dry-type reactor on the low-voltage side of the 500 kV transformer.The best configuration plan is explored based on the analysis of reactor faults and the actual operation in recent years.
