    Abstract: Based on Cassie and Schwarz arc models, with the help of Simulink platform in Matlab, this paper carried out simulation analysis for the arc characteristics inside medium voltage direct current circuit breakers. The parameter scanning strategy was used to research on the transient response of arc voltage and current for each model, so as to determine the impacts of each parameter in the model on the output result. Via comparing the simulation results with the experimental results, the correctness of Schwarz arc model is verified, which is suitable for the research of medium voltage direct current circuit breakers arc.
    Key words: direct current circuit breaker; direct current arc; Cassie model; Schwarz model; medium voltage direct current system
