摘　　要：本文源于一起电抗选型设计失误而导致高压调谐电抗器烧毁事故分析过程而引起的思考,通过对国外电力电容器选型设计计算正确指导,进而引起对调谐电抗器设计与选型问题重新认识,说明高压调谐型铁心电抗器因设计容量不匹配,会给系统运行所带来严重危害,最后延伸探讨了高压调谐型铁心电抗器不同形式匹配失误(选型过大或偏小),都会给系统稳定运行带来一定事故隐患或危害,为处理类似事故提供了很好的帮助。This article is originated from an accident of high voltage tuning reactors burnout caused by errors of type selection and design of reactor. Through the correct guidance of type selection and design calculation of foreign power capacitors, re-thinking of design and type selection of tuning reac- tor is initiated further, showing that mismatching of design capacity of high voltage tuning core reactor brings serious harm to the system. And, finally, different types of incorrect matching of high voltage tuning iron core reactor （type selection is too big or small） will bring a definite hidden fault or dan- ger to system stability, which provides good help for the treatment of similar fault.
