摘　　要：目前,CVT(电容式电压互感器)在我国电力系统中的应用越来越多,铁磁谐振问题成为影响CVT稳定运行的关键问题。本文的主要目的正是对铁磁谐振问题进行全面的总结,并提出具有一定借鉴作用的解决方法。针对某条线路的500kV电容式电压互感器铁磁谐振问题进行了系统的介绍、分析。采用了理论与实际结合的方法,概括总结阻尼器的种类和优缺点,并提出了500kV铁磁谐振问题具体改进措施,对同类问题的解决具有一定的参考价值。Currently, capacitor voltage transformers are used in the chinese power system more and more, ferro-resonance problem becomes the main problem which impacts the system stable operation . The main purpose of this paper is on issues of ferromagnetic resonance comprehensive summary, which will even give the helpful solutions. For certain lines of 500kV capacitor voltage transformer ferro-resonance issues systematic introduction and analysis. In this article We take the Theory and practical methods, besides, we also conclude the types, the advantages and disadvantages of the dampers .in the end we＇ll bring forward the specific measures for improvement, which will be good to the same kind of problem.
