摘要：
For DC vacuum circuit breakers used in high current and high di/dt breaking environments, the post-arc transient process with insulation recovery as the main feature directly affects their breaking characteristics. During the development of the sheath, the electric field strength and power density of the cathode surface after the end of arcing are the two factors that cause arc reignition. From the perspective of improving the recovery capability of the medium after the arcing, different test schemes were carried out at the peak arc current of about 23kA and the rate of the arc-extinguishing current of about 300A/μs. Moreover, based on continuous transitional sheath modeling, the variables such as contact opening dynamic process and the effective diameter of the arc are introduced. The design of commutation circuit parameters is guided based on the improved arc model. Finally, the equivalent analysis of PSCAD/EMTDC electromagnetic transient simulation and test is carried out. It is shown that the arc re-ignition trend of the vacuum circuit breaker after the arcing in the test is consistent with the simulation results, and the type of re-strike can be determined through the simulation results. Therefore, the improved post-arc electromagnetic transient modeling of vacuum circuit breaker is verified. © 2021, Electrical Technology Press Co. Ltd. All right reserved.
