The invention discloses an electronic ground automatic neutral section passing device. The electronic ground automatic neutral section passing device comprises a train direction and position detection unit, an electronic switching valve bank unit and a central controller unit. By detecting the voltage of an alpha phase, a neutral section and a beta phase, the central controller unit determines the optimal switch-on moment according to train running direction and arrival position signals output by a train position signal processing unit so as to achieve the effect of minimum overvoltage impact and minimum overcurrent impact, and the central controller unit sends synchronous triggering switch-on or switch-off signals so as to achieve the ground automatic neutral section passing function of a train. By means of the electronic ground automatic neutral section passing device, train operation time is shortened, line carrying capacity is improved, the service life of high-voltage electrical equipment on the train is prolonged, and operation and maintenance cost is reduced.
