The invention discloses an electrified railway arc extinction automatic neutral section passing system and a control method thereof. The electrified railway arc extinction automatic neutral section passing system comprises an electric neutral section, a thyristor switch device, a follow current resistor, a vacuum switch device, a train position recognition device and a control unit. The electric split-phase comprises a sectionalizer I, a neutral section and a sectionalizer II; the thyristor switch device is connected in parallel to two ends of the sectionalizer I and the sectionalizer II; and the vacuum switch device is connected in parallel to the two ends of the sectionalizer I, or the vacuum switch device is connected in parallel to the two ends of the sectionalizer II, or the vacuum switch device is connected in parallel to the two ends of the sectionalizer I and the sectionalizer II. The method can effectively reduce or eliminate the arc discharge phenomenon caused by the ground control automatic passing neutral section device based on the thyristor switch in the process that the train pantograph passes through the sectionalizer of the electric split phase, and can effectively suppress the transient electrical process and the overvoltage and overcurrent problems.
