摘　　要：消弧线圈串联非线性阻尼电阻,克服了自动跟踪消弧装置中线性阻尼电阻并联短接装置的固有缺点,改善了手动调谐消弧线圈的运行状况,从而提高了电网的安全性。从南京西华门变电站10kV电网消弧线圈串联非线性电阻器的现场试验及近一年的运行经验证明,新产品——DFD型大功率非线性电阻器将会在消弧线圈接地系统中得到广泛应用。The application of the nonlinear damping resistor connecting in series with arc suppression coil, can overcome the inherent shortcoming of the linear damping resistor shunt short-circuit apparatus in the automatic tracing are suppression apparatus, can improve the operating condition of the manual adjustment resonance arc suppression coil, and thus can enhance the security of power distribution network. The field-test and the nearly one year's running experience of the nonlinear resistor and the are suppression coil in series at the Nanjing Xihua Men Transformer Substation of 10kV power distribution network have stronly proved that the new product-DFD type high power nonlinear resistor can be widely used in the grounding system by the arc suppression coil.
