A method and a device for ground passing neutral section suppression of magnetizing inrush current of a traction transformer, includes: determining a no-power time interval of a traction transformer (S301) according to an acquired first phase angle of a voltage of a second feeding section that is lagging behind a phase angle of a voltage of a first feeding section, an acquired second phase angle of a voltage of primary current of the traction transformer that is lagging behind the phase angle of the voltage of the first feeding section when a locomotive is powered by the first feeding section, and an acquired off moment of a first power electronic switch corresponding to the first feeding section (S300); and determining an on moment of a second power electronic switch corresponding to the second feeding section according to the off moment of the first power electronic switch and the no-power time interval, such that the magnetic flux of the traction transformer is located within a preset magnetic flux range (S302).
