The invention discloses a kind of AC electrified railway intelligent neutral section device. It consists of a first switch which connects the first power supply arm to the neutral section and its parallel impedance, a second switch which connects the second power supply arm to the neutral section and its parallel impedance, current and voltage sensors detecting the first switch and current and voltage sensors detecting the second switch etc. The device can automatically identify the train's pantograph position through the voltage information at both ends of the first switch and the second switch and current information flowing from the first switch and the second switch, and automatically close or open the first switch and the close or open the second switch to make the neutral section obtain or cut off the electric energy of power supply arm according to the identified location of the pantograph. The circuit structure of the switch and its parallel impedance can be replaced by the circuit structure of connecting two ends of a step-down transformer and its low-voltage winding to a switch. There is no need to install the train position detection device, with advantages of a simple structure and convenience of use and maintenance.
