Abstract
A direct-current circuit breaker includes a first main circuit breaker inserted into a first direct-current line, a resonance circuit connected in parallel to the first main circuit breaker, a MOSA connected in parallel to the first main circuit breaker via the resonance circuit, a second main circuit breaker inserted into a second direct-current line, a switch connected in series to the second main circuit breaker, a resonance circuit connected in parallel to the second main circuit breaker, and a MOSA connected in parallel to the second main circuit breaker via the resonance circuit. The second direct-current line is a line that branches off from the first direct-current line and returns to the first direct-current line. The switch is inserted upstream of the second direct-current line.
