Abstract:A high-voltage direct-current circuit breaker is a key equipment to construct a flexible direct current transmission system. Most of the existing design schemes have some shortcomings such as slow fault-breaking speed, poor current-limiting effect, large capacity of the arrester, and long reclosing operation time. To solve the above problems, this paper proposes an H-type high-voltage direct current circuit breaker with a current-limiting function. The current-limiting inductance is put into operation by judgi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
