The short arc ignition and its characteristics were analysed. It was also pointed out that contact bounce duration decided the closing short arcduration.
分析了短电弧的产生机理和基本特性，指出了触点弹跳时间决定闭合短电弧的时间。

According to the dynamic behavior of the breaking current, breaking arcduration is extract from the breaking current waveform by using the concept of moving average of statistics.
利用分断电弧过程中的电流动态特性，使用移动平均法提取了每次分断电流的燃弧时间。
