The high-voltage circuit breaker is characterized in that a pulse-driven linear motor type magnetic mechanism is used for driving the arc extinguish chamber of a high-voltage circuit breaker to move, thereby realizing the switching-off and switching-on movement of the high-voltage circuit breaker. A permanent magnet is adopted in the pulse-driven linear motor type magnetic mechanism to match the magnetic circuit therein, thereby leading to the upward and downward movement of a live coil therein under the effect of ampere force. The switching-off and switching-on positions are maintained through the closure of the magnetic circuit. The excitation of the coil is provided by a pulse capacitor, and the coil and the pulse capacitor are controlled by an external control system. The utility model solves the technical problem that the traditional electromagnetic mechanism can not realize the long-stroke and high-power operation and the technical problems of actuation accuracy and speed control of the operating mechanism of the existing ultra-high-voltage circuit breaker. The whole circuit breaker system has the advantages of simple control, direct operation and low cost.
