高速受电弓和普通受电弓一样,是由集电头(即弓头)、框架、底架和传动机构四个部分组成。众所周知,受电弓安装在车顶盖上,工作时其滑板和接触网的接触导线相接触,将电流引入机车或动车内。由于接触网是一个重量和弹性都不均匀的弹性系统,其接触导线的高度也不是恒定的,而运行中受电弓底架又不断地受到机车和轮轨传来的机械振动作用,除此之外,还有风和高速气流的空气动力作用,所以,在运行中受电弓滑板和接触导线之间的
Like high-speed pantograph and pantograph, it is composed of collecting head (ie bow head), frame, chassis and transmission mechanism. It is well-known that pantographs are mounted on the roof of a car and contact with the contact wires of the catenary during operation, directing current into the locomotive or motor car. As the catenary is an elastic system with uneven weight and elasticity, the height of the contact wire is not constant. However, the pantograph base under running continuously receives mechanical vibration from the locomotive and wheel rail. In addition, there is the aerodynamic effect of wind and high-speed airflow, so between the pantograph slide and the contact wire during operation
