摘要: The present invention discloses a magnetic pulse inducted transfer-type DC circuit breaker. The DC circuit breaker comprises a main current circuit and a transfer current circuit, the main current circuit comprising a combination of a fast mechanical switch or a mechanical switch with a power electronic device; the transfer current circuit comprises an arrester and a mutual inductor. The voltage generated through a mutual inductor may directly transfer current to the arrestor, thereby eliminating a process of transfer of the current to the capacitor or a power electronic device; it has a high current limiting or breaking speed, with a stability far superior to traditional technologies. The isolation between the capacitance charging unit and the DC system significantly reduces the voltage level and size of the charging unit, and enhances action reliability. The power semiconductor devices or trigger gaps are used at the primary side of the mutual inductor of the transfer current circuit form a bridge circuit, thereby realizing bidirectional current transfer; the bridge circuit is voltage-withstanding and low-cost.

摘要: In a DC circuit breaker device, first and second semiconductor switches are connected in series on a main circuit line such that current-carrying directions of the switches are opposite to each other. A first diode is connected in anti-parallel with the first semiconductor switch, and a second diode is connected in anti-parallel with the second semiconductor switch. First and second mechanical circuit breakers are connected in series with each other and in parallel with the whole of the first and semiconductor switches. First and second backward current generation circuits are connected in series with each other and in parallel with the whole of the first and second mechanical circuit breakers. An injection switch is connected between a node between the first and second mechanical circuit breakers and a node between the first and second backward current generation circuits.
