The embodiment of the invention provides a pantograph and a train. The pantograph comprises a sliding plate, a first arm rod, a second arm rod and a flow guide cover which are sequentially connected. The second arm rod is provided with a windward side and two leeward sides, the windward side and the two leeward sides form a triangular prism shape, the middle of the windward side protrudes and is gradually bent from the middle to the two sides to guide air to the leeward sides on the two sides, the leeward sides are provided with a plurality of flow guide strips, and the flow guide strips are arranged in parallel at intervals to form a wave shape. A gap between every two adjacent flow guide strips leads to the joint of the two leeward sides from the windward side; the air guide cover guides air to the windward side and the leeward side of the second arm rod; by optimizing the shape of the second arm lever and arranging the air guide cover, air resistance and dipole noise in the train running process can be reduced.
本申请实施例提供了一种受电弓及列车,受电弓包括依次连接的滑板、第一臂杆、第二臂杆和导流罩;第二臂杆设有迎风面和两个背风面,迎风面和两个背风面形成三棱柱形状,迎风面的中部凸起并从中部向两侧逐渐弯曲以将空气导向两侧的背风面,背风面设有多条导流条,多条导流条平行地间隔设置以形成波浪状,相邻的两条导流条之间的间隙从迎风面通向两个背风面的连接处;导流罩将空气导向第二臂杆的迎风面和背风面;通过对第二臂杆形状的优化和设置导流罩,能够减小列车运行过程中的空气阻力和偶极子噪声。
