Abstract The post-arc characteristic of mechanical DC circuit breaker is an important parameter to characterize its breaking performance. In order to obtain the influence law of vacuum switch post-arc current, post-arc action time, di/dt and du/dt near current zero point during DC breaking process, this paper firstly analyzed the post-arc current of mechanical vacuum DC circuit breaker based on current transfer measurement principle. Then, the parameters of the mechanical DC circuit breaker arc current measurement device were designed, and a mechanical DC breaking experiment platform based on the forced zero crossing method was built. The mechanical vacuum DC circuit breaker arc was measured under the condition that the breaking current was 1.5kA, and the influence of the commutation frequency and the recovery voltage on post-arc current was discussed. The results show that the post-arc current measuring device based on current transfer can effectively measure the post-arc current. The increase of the commutation frequency and the recovery voltage will cause the post-arc current to increase. The recovery voltage slightly lags behind the post-arc current in phase by about 100 ns, and the change influence of the directional frequency on the post-arc current is greater than that of the recovery voltage, which provides a reference for the optimization research of the circuit breaker's breaking performance.
