真空断路器弧后相位是中压电流中断时介质恢复的关键相位。一个二维混合模型旨在了解这一阶段，并评估在这一阶段的电路断开故障的风险已经开发。在本文中，我们展示了恢复电压如何将等离子体从间隙中驱逐出来，并说明了屏蔽极性的影响。
The post-arc phase of a vacuum circuit breaker is a critical phase for dielectric recovery in the context of medium voltage current interruption. A 2-D hybrid model aimed at understanding this phase and at evaluating the risk of circuit-breaking failure during this phase has been developed. In this paper, we show how the recovery voltage expels the plasma from the gap and illustrate the influence of the shield polarity.
