N2 - Multi-terminal DC (MTDC) transmission technology has the advantages of large transmission capacity and flexible control. The HVDC High Speed Switch (HSS) is a key device for fault isolation in MTDC transmission systems, contributing to system reliability and availability. Despite HSS only needs to interrupt the no-load charging current of tens of amps, little research has been done on the arc characteristics of interrupting the DC arc by using the arc negative resistance characteristics in the high-voltage field. In this paper, the interruption experiment of 20A DC current was carried out on the HSS filled with SF6 at 0.6 MPa, and the voltage and current characteristics of the arc were simulated by the Mayr arc model. In addition, a 2-D MHD model of arc combustion process is established to analyze the temperature and pressure distribution law in the arcing chamber. Based on the consistency of experimental and simulation results, the established model in this paper is valid and can provide a reference for the structural design and optimization of the HSS.
