摘　　要：干式铁心串联电抗器是无功补偿装置中的重要元件,起到保护电容器组及消除电网谐波的作用。其使用不当或配置不当容易造成非常严重的后果,可能造成谐波放大或电抗器损毁。文中介绍一起干式铁心串联电抗器在电力系统中运行损坏的事故,对电抗器非正常振动作了简单的分析,找出串联电抗器的噪音异常增大的原因,提出了解决方案,可供运行维护人员参考。Dry type iron core series reactor is an important element in reactive power compensation device and plays the role in protecting capacitor bank and eliminating grid harmonics. Incorrect use or configuration will easily cause very serious consequences and likely results in harmonic enlargement or damage reactor. In this paper, the damage of dry type iron series reactor during operation in the power system is introduced, simple analysis on normal vibration of reactor is made, the reason on abnormal increase of noise of the series reactor is found out and corresponding solution is proposed, which can provide reference to the operation and maintenance staffs.
