| 摘 要： | 由电弧启动到正常工作这段时间，电网线路的电流电压波动性较大，往往给电路其它各元件造成强烈的冲击。据此，利用电弧伏安特性曲线对电网电路非稳态过程进行了分析，并理论推导了既适合电路稳定性要求又能保证电弧具有理想输出功率的最佳电网阻抗匹配值，现实上对正确使用直流电弧具有重要意义。

| Abstract: | From starting-up to stabilization of the arc, the electric current and voltage usually fluctuate acutely, which makes a great impact on other circuit components.And so, unsteady process of the power network is analyzed through volt-ampere characteristics curve of the arc and optimal impedance matching of the power network, which can both meet the electric steady requirements and assure that the arc has satisfactory output power, is also deduced. This paper has a great importance for guiding to use correctly Dc-Arc in practice. |
