| Summary: | According to the characteristics of plateau diesel locomotives, i.e. high operating altitude, complex heat dissipation conditions and high lightweight requirement, this paper introduces the main circuit structure, working principle and design method for the traction converter of Fuxing plateau dual-source power centralized diesel multiple units(DMU). For high operating altitude, the in-cabinet electrical insulation performance was strengthened by the altitude correction method; for complex heat dissipation conditions, a reasonable cooling scheme was selected and the detailed thermal design for the loss and heat dissipation capability of the whole cabinet was carried out to ensure its heat dissipation capability; for high lightweight requirement, the modular layout and finite element structural simulation method were used to ensure the structural strength and realize lightweight design at the same time. The tests show that the traction converter can meet the requirements of all performance indicators. |
