Provided in the invention is a hybrid active high-voltage direct-current circuit breaker comprising a main branch circuit, a converter branch circuit, an energy consumption branch circuit, a current-limiting inductor, a residual direct-current circuit breaker and a high-voltage ignition sphere gap for protection. The direct-current circuit breaker has advantage of simple circuit topological structure, simple and convenient control, high security and reliability, and fast motion; the used power electronic devices are mainly semi-controlled and uncontrolled ones, so that the number of control trigger circuits of the power electronic devices is reduced; the technology is mature and is easy to realize; the through-current capacity and the breaking current capability are great and the voltage-withstanding level is high; the expansion capability is excellent. Moreover, the high-voltage ignition sphere gap with the low cost and the mature technology is used as a discharging and protection switch, so that the cost is reduced substantially, the reliability is enhanced, and the equipment security is protected.
