Louver type waterproof assembly for traction converter cabinet
The invention relates to a traction converter cabinet heat dissipation technology, in particular to a louver type waterproof assembly for a traction converter cabinet. Effective ventilation and heat dissipation of the traction converter cabinet are achieved, dust and water drops are prevented from entering the traction converter cabinet, the electromagnetic compatibility requirement is met, and reliable and safe operation of the traction converter cabinet is comprehensively guaranteed. A louver-type waterproof assembly for a traction converter cabinet comprises a support frame enclosed by front, back, left and right support frames. A plurality of fan blades which are arranged in parallel are mounted in the supporting frame; the fan blades are installed between the left supporting frame and the right supporting frame in the left-right direction and provided with water guiding grooves in the left-right direction, and the installation positions of the left ends of the fan blades are lower than the installation positions of the right ends of the fan blades. A gap is formed between every two adjacent fan blades, and the projection of all the fan blades on the horizontal plane is a fully-closed surface; a groove with the length covering all the fan blades is formed in the left side supporting frame and serves as a water collecting groove; and the water collecting tank is communicated with all the water guide grooves. When the fan blades are seen from bottom to top, a metal closed area is formed, and electromagnetic interference can be effectively weakened; the processing procedure is simple and easy to implement, and the cost is low.
本发明涉及牵引变流柜散热技术，具体为一种牵引变流柜用百叶窗式防水组件。实现了牵引变流柜有效通风散热，避免灰尘及水滴进入，满足电磁兼容要求，全面保障牵引变流柜可靠安全运行。一种牵引变流柜用百叶窗式防水组件，包括由前后左右四个支撑架围成的支撑框架；支撑框架内安装有多个相互平行排列的扇叶；扇叶呈左右走向安装在左右支撑架之间，扇叶上设有左右走向的导水槽且扇叶左端的安装位置低于右端；相邻扇叶之间有间隙且所有扇叶在水平面的投影呈全封闭面；左侧支撑架上开有长度覆盖所有扇叶的凹槽作为集水槽；所述集水槽与所有导水槽相连通。扇叶从底部往上看，形成金属封闭区域，能有效减弱电磁干扰；加工工序简单易实现，成本较低。
