摘要

针对高原型内燃机车运行海拔高、散热工况复杂和轻量化要求高的特点，文章介绍了一种复兴号高原双源动力集中动车组内燃车牵引变流器的主电路结构、工作原理及其设计方法。对于运行海拔高的特点，使用海拔修正的方法对柜内电气绝缘性能进行加强；对于散热工况复杂的特点，选择合理的冷却方案，并对整柜的损耗和散热能力进行精细化热设计，确保其散热能力；对于轻量化要求高的特点，使用模块化布局和有限元结构仿真的方法，在保证结构强度的同时实现轻量化设计。试验表明，牵引变流器能满足各项性能指标要求。

Abstract

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.
