摘要

高速列车车顶高压设备裸露于室外，易受环境影响产生积污。针对高速列车车顶受电弓绝缘子区域的流场特性进行仿真计算，分析高速列车运行情况下的流场结构，对3 种不同导流罩下的车顶高压设备流场特性进行对比，得到了不同导流罩对高压设备区域流场的影响。结果表明：侧板型导流罩可增加绝缘子周围气流速度，避免污物沉积。

Abstract

The high-voltage device on the roof of the high-speed train are always running in the open air,which are easily polluted by the atmospheric pollutants. The simulation calculation was done to the flow field characteristics of the pantographic insulator region for the roof of the high-speed train, the flow field structure was analyzed. Three designs of the train roof devices were assessed. It has been found that the side panel design increased the wind velocity in the roof area and reduced the contamination level of the insulators.
