| 摘 要： | 通过试验研究了小电流真空电弧不稳定时电弧电压、电弧电流的高频变化过程，观察到电弧不稳定过程中存在许多不成功截断，导致电弧电压和电弧电流波形上叠加高频分量。负载电容、触头并联电容和回路连线电感等对电弧电压、电弧电流的高频过程具有不同的影响；也影响真空开关的截流值。

| Abstract: | In this paper, the high frequency transient components of the vacuum arc voltage and current were investigated experimentally. It was observed that many unsuccessful choppings happened in the arc unstable processes, which induced the high frequency oscillation of the arc voltage and current. The load capacitance, the contact parallelled capacitance and the connecting wire inductance have different influences on the high frequency transient components and the chopping currents. |
