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.
