摘要（英）：

The invention relates to a high voltage direct current circuit breaker for direct current transmission. The circuit breaker is characterized in that the circuit breaker comprises a large resistance value inductor, a trigger switch, a diode, a protection capacitor, a small resistance value inductor, an alternating current circuit breaker and a grounding switch; the large resistance value inductor and the alternating current circuit breaker are connected in series in a direct current line; the diode, the protection capacitor and the small resistance value inductor form a charging circuit; the first end is connected between the large resistance value inductor and the alternating current circuit breaker, and the tail end is directly grounded; the trigger switch is connected in parallel with the diode; and the grounding switch is connected with the line side of the alternating current circuit breaker. According to the invention, the cost of a device can be reduced; when the device is in normal operation, conduction loss is prevented; and the high voltage direct current circuit breaker can be widely applied in the technical field of high voltage direct current transmission.
