摘　　要：根据电容式电压互感器(CVT)的等值电路,建立了基于速饱和电抗型阻尼器CVT的铁磁谐振阻尼模型,从理论上推导了CVT阻尼条件。结合江苏无锡日新220 kV的电容式电压互感器(CVT)实际参数值,计算了阻尼器串联电阻的数值。结果表明,该理论很好地解决了阻尼器串联电阻的选择难题,可用于指导CVT的工程设计。Based on 220 kV capacitive voltage transformer（CVT） equivalent circuit, a model of ferromagnetic resonance damping of CVT with series saturation reactor damper is built, with which a damp condition is derived theoretically. Combined with the data of 220 kV CVT obtained from Jiangsu Wuxi Nissin Co.,Ltd., the value of damp resistance is calculated. Simulation results are consistent with the experimental,which is shown that the proposed theory is validated and it can be use to design CVT with no ferro-resonance under certain condition.
