摘要
介绍了三相五柱式消弧线圈的工作原理,单相电弧接地过电压的工频熄弧理论。对三相五柱式消弧线圈单相电弧接地过电压的等值计算电路进行了仿真分析,说明了电网中性点经并有阻尼电阻的三相五柱式消弧线圈接地具有明显的优点,既可减小出现过电压的概率,又降低过电压的幅值。
The principle of arc-suppression coil with three phases and five columns,and theory of power frequency extinguishing arcing were introduced.Marked advantages of damping resistor-both falling the probability and decreasing amplitude of overvoltage were pointed out by simulating and analyzing the circuit describing single phase arcing grounding overvoltage.
