Abstract
Disclosed embodiments relate to a DC circuit breaker and a circuit breaking method thereof which comprises: a measuring portion for measuring a DC current conducted through a first circuit portion; the first circuit portion for conducting and blocking the DC current; and a second circuit portion for conducting and blocking the DC current which is bypassed from the first circuit portion and controlling the open/close operation of the first circuit portion according to a measuring result of the measuring portion, wherein, in the first circuit portion and the second circuit portion, switching elements, which are included in each of them, are connected in a parallel configuration such that a high switching operation during a blocking operation can be improved and the DC current can be blocked in a safer and more efficient manner, and a circuit breaking method of the DC circuit breaker.
