Abstract
A hybrid high-voltage DC breaker, consists of a plurality of completely identical breaker modules connected in series. Each of the breaker modules comprises a main current circuit, a transfer current circuit, an over-voltage limiting circuit and a control system, wherein a high-speed mechanical switch, the transfer current circuit and the over-voltage limiting circuit are connected in parallel. The transfer current circuit consists of circuits 1-4, wherein the circuit 1 and the circuit 4 are connected in series at first and then connected with the main current circuit in parallel; a pre-charged capacitor is connected with the circuit 4 in parallel after being connected with the circuit 3 in series; and, one end of the circuit 2 is connected with the left end of the main current circuit while the other end thereof is connected with a connection point of the pre-charged capacitor and the circuit 3.
