Abstract (en)

A direct current circuit breaker is provided at a coupling point where three or more direct current power transmission lines (11 to 13) are electrically coupled in a direct current power transmission line network. The direct current circuit breaker includes three or more series circuits (2), each of the series circuit being connected to ends of two different direct current power transmission lines, and including a serial connection of two or more current disconnectors (21), and three or more wire connection circuits (3), one end of each of the wire connection circuits being connected to a middle point of the series circuit, and another end being connected to one point where other ends of the wire connection circuits are connected to, each of the wire connection circuits including a commutation circuit (31) in which a current is commutated.
