due to its inherent advantages

has become a research focus boh at home and abroad. At present

medium-voltage DC circuit breaker has been widely used in DC distribution networks and is a critical equipment to ensure safe and reliable operation of DC systems. In this paper

based on the current development status of both DC distribution networks and medium-voltage DC circuit breaker

the technical analysis on the breaking test of medium-voltage DC circuit breaker is developed.The papers bagins with a general review of the research status

breaking principles and main types of the medium-voltage DC circuit breaker.The breaking testing technology of the medium-voltage DC circuit breaker is then

analyzed

with a particular focus on test method of breaking testing verification of the DC breaking performance of the medium-voltage DC circuti breaker. The existing test conditions both at home and abroadd are compared.The priniple of the synthetic test using low-frequency short-circuit generator is prticularly introduced and corresponding simulation analysis is performed. The research content in this paper is of great significance to the development of testing technology for key equipment in DC distribution networks.
