| 摘 要： | 电容式电压互感器由电容元件和非线性电感组成，当有外部扰动时，电容式电压互感器内部有可能产生铁磁谐振．导致二次电压异常升高。在一起电容式电压互感器二次电压异常情况处理过程中，通过二次回路检查、停电试验和解体检查等步骤，分析认为引起电容式电压互感器二次电压异常升高的主要原因是发生铁磁谐振以至烧毁阻尼器．并从理论上对该现象进行了深入分析，最后提出建议以预防类似故障的发生。

| Abstract: | Capacitor voltage transformer is composed of capacitance components and non-linear inductance.The ferromagnetic resonance may arise within capacitive voltage transformer(CVT) and lead to abnormal rise of secondary voltage when external disturbance occur.In this paper,in dealing with the CVT secondary voltage rise,it's suggested that CVT secondary voltage abnormal rise is mainly due to the ferroresonance and burn-out of damper with harmonic elimination based on the secondary circuit checking, power failure t... |
