摘要:
介绍了地铁列车再生制动能馈系统的工作原理,给出了一种基于模块化设计思路的能馈变流器结构设计方案。通过建立变流器柜的三维结构仿真模型,对柜内散热系统进行了热场分析;通过柜内温升试验及风速测试,验证了变流器散热系统结构的合理性。试验及测试结果表明,再生制动能馈变流器体积小、重量轻,不仅满足了产品的设计要求,还解决了变流器柜内散热效果不好的问题。
Abstracts:
The working principles of metro train regenerative braking energy (MRBE) feedback system is introduced, a structural scheme design of MRBE feedback converter based on modular design idea is presented. Through establishing a 3D simulation model of converter cabinet, the thermal filed of internal cooling system is analyzed, and the rationality of internal cooling system is verified through experiment of the converter temperature rise and wind velocity. The results show that the MRBE feedback converter could fulfill the product design requests and solve the problems of poor cooling effects in converter cabinet owing to the small size and light weight.
