摘　　要：受电弓是电力机车最重要的高压电器之一,其控制原理和电路分析是高职院校铁道机车专业学生需掌握的核心技能。分别梳理SS9直流机车和HXD3交流机车两种典型的电力机车受电弓控制原理,使用Multisim软件对其控制电路进行仿真建模,编写控制逻辑程序,交互仿真升弓、降弓、电钥匙互锁等功能,直观地观察到电路原理图、仿真响应、测试参数,为机车受电弓控制电路的教学提供良好的平台。Understanding the control principles and circuit analysis of pantographs,one of the most critical high-voltage components in electric locomotives,is essential for students majoring in railway locomotive engineering at higher vocational colleges.This study focuses on the pantograph control systems of two representative electric locomotives:the SS9 DC locomotive and the HXD3 AC locomotive.Using Multisim software,the study developed simulation models of the control circuits for both locomotive types and implemented control logic programs.The study simulates key interactive functions,including raising and lowering the pantograph and electric key interlocking.This approach allows for direct observation of circuit diagrams,simulation responses,and test parameters,providing an excellent platform for teaching locomotive pantograph control circuits.
