Recently,　low-voltage,　medium　voltage　and　high　voltage　DC　transmission　and　distribution　system　has　been　in　a　period　of　rapid　development.　DC　circuit　breaker　has　also　become　a　new　hot　research　area　in　electrical　engineering.　Switching　arc　plays　a　significant　role　in　the　DC　current　interruption　which　is　formed　in　the　interrupting　process　of　DC　circuit　breaker　(DCCB).　The　control　of　arc　evolution　and　extinction　is　one　of　the　most　important　problems　to　be　solved　in　the　development　of　DCCB.　According　to　the　differences　of　breaking　principle　and　work　voltage,　there　mainly　have　been　three　types　of　DCCB　related　to　arc　phenomenon,　such　as　air　circuit　breaker,　self-excited　oscillation　circuit　breaker　and　hybrid　circuit　breaker.　In　this　paper,　previous　simulation　and　experimental　works　on　the　switching　arc　phenomenon　in　these　DCCB　are　reviewed.　And　some　points　for　the　future　development　needs　are　presented.
