摘　　要：受电弓是实现电力机车从接触网取得电能的重要设备,安装在机车车顶上。负荷电流通过受电弓滑板接触面的流畅程度与接触压力、过渡电阻、接触面积有关,本文重点对电力机车受电弓的工作状态进行研究,并针对其中的常见故障进行分析,并结合实际情况介绍了相应的维修策略。The pantograph is an important equipment for electric locomotive to obtain electric energy from the catenary,which is installed on the locomotive roof.The smoothness of the load current through the contact surface of the pantograph slide is related to the contact pressure,transition resistance and contact area.This paper focuses on the working state of the electric locomotive pantograph,analyzes the common faults,and introduces the corresponding maintenance strategy according to the actual situation.
