Abstract: Introduction was made to the significance of the direct current (DC) circuit breaker as one DC system component. This paper analyzed and compared the difference between electric power project DC system design technical code of new version and that of old one. This paper researched on the requirement of the type selection and stage difference coordination of DC circuit breaker. Taking real project for case and combining with the on-site debugging and data analysis, this paper obtained the type selection and coordination method, which guides?the application of new DC technical code for the designers, and also ensures the design reliability of DC system.
Key words: direct current technical code; direct current circuit breaker; type selection; stage
