Abstract:
Provided are a method and apparatus for handling a grid-side converter apparatus of a multi-current electric locomotive. The method comprises: determining a target power supply standard of a multi-current electric locomotive (S101); under said target power supply standard, connecting in a target manner the input end of a sub-module using an intermediate frequency transformer in the grid-side converter apparatus (S102); connecting in said target manner the input end of said sub-module, then separately connecting to both a power supply grid and a ground (S103). The described method solves problems in the related art such as the large volume and weight and high difficulty and cost of manufacture of a transformer required for a grid-side converter apparatus of a multi-current electric locomotive.
