摘要
随着中国轨道交通车辆技术的不断发展和速度的提升,对牵引变流器,变压器用复合冷却复合冷却塔提出了更高的要求;冷却塔在满足性能的前提下,具有更优,更合理的设计.文中主要针对复合冷却塔进风口过滤网阻力测试方法进行了研究,得到不同过滤网局部阻力系数和阻力曲线,提出了一种更合理的滤网结构.
With the development of China’s rail transit locomotives technology and improvement of speed,higher requirements are put forward for the cooling tower,which provide cooling for traction converters and transformers:on the premise of satisfying performance,cooling tower has better and more reasonable design.For this article mainly study the resistance measurement method of filter screen for inlet of compound cooling tow-er,the local resistance factor and resistance curve of different filter screen are obtained,and a more reasonable filter screen structure is proposed.
