弧后电流可以反映电极间隙中残留等离子体和零区特性，因此对断路器的分断有很大影响。本文设计了一种永磁斥力混合作动器，并建立了弧后电流测量系统。基于强制电流过零法，在真空灭弧室综合试验电路中进行了一系列高频直流开断实验。研究了换相频率和恢复电压对真空直流开断的影响。结果表明，弧后电流与恢复电压之间存在约80ns的短滞后阶段。高换相频率导致弧后电流增大，不利于真空直流开断。弧后电流也随着恢复电压的增加而增加。中断不仅仅受di/dt 和du/dt 的影响。本研究中，当瞬态恢复电压接近2800 V时，会发生首次电流过零时的失败中断，在高换相频率下容易发生电流斩波。斩波电流值与换相频率成正比，在 4.0kHz 时斩波电流高达 120 A。
Post arc current can reflect the residual plasma in the electrode gap and the zero zone characteristics, so it has a great influence on the interruption of the breakers. In this paper, a permanent magnet-repulsive force hybrid actuator is designed, and the post arc current measurement system is established. Based on the forced current zero method, a series of high frequency DC interruption experiments are carried out in the synthetic test circuit with vacuum interrupters. The influence of the commutation frequency and recovery voltage on the vacuum DC interruption is investigated. The results show that a short lag phase about 80 ns exists between the post arc current and recovery voltage. High commutation frequency leads to the rise of the post arc current, which is disadvantageous for the vacuum DC interruption. The post arc current also rises with the increase in the recovery voltage. The interruption is not just affected by the di/dt and du/dt. In this study, failing interruption at the first current zero happens when the transient recovery voltage is near 2800 V. The current chopping occurs easily at high commutation frequency. And the chopping current value is proportional to the commutation frequency, which is up to 120 A at 4.0 kHz.
