The present invention discloses an automatic split phase crossing system and method for electrified railway section posts. The system comprises: a pantograph identifier for sensing a traveling position and direction of a train; a voltage transformer for detecting a voltage of a first power supply arm; a first resistor and a first thyristor switch, which are connected to two ends of a first sectionalizer in parallel, respectively; a second resistor and a second thyristor switch, which are connected to two ends of a second sectionalizer in parallel, respectively; and a control unit for executing the following operations: in the event that the train travels from the first power supply arm to the first sectionalizer, controlling the first thyristor switch to be turned on during voltage zero-crossing of the first power supply arm; in the event that the train travels from the first power supply arm into the neutral section via the first sectionalizer, controlling the first thyristor switch to be turned off and simultaneously controlling the second thyristor switch to be turned on by means of current zero-crossing of the first thyristor switch for the time being; and in the event that the train travels from the neutral section into the second power supply arm via the second sectionalizer, controlling the second thyristor switch to be turned off.
