摘　　要：驼峰电空转辙机广泛应用于大、中、小型自动化编组站驼峰场,是实现自动控制的执行单元,其性能好坏与稳定决定着编组效率。文章针对驼峰电空转辙机控制电路在特定条件下因迂回条件的构成形成迂回电路,并造成控制设备表示继电器的高频颤动及驼峰电空转辙机电磁阀非常规供电的问题,结合驼峰电空转辙设备与控制电路的特点,提出了改进措施,为同类项目提供参考。Hump electro-pneumatic switch machine,the executive unit to achieve automatic control,is widely used in large,medium and small hump automation marshalling yard. Whether its performance and stability are good or not decide the marshalling efficiency. In this paper,the roundabout route appears when the circuit of the electro-pneumatic switch machine works under the extreme condition in the practical application,which leads to high-frequency vibration of the relay for the indication of the control equipment,and the electrical magnetic valve of the electro-pneumatic switch machine is abnormally supplied the power. Combined with the characteristics of the equipment and control circuit of the electro-pneumatic switch machine,improvement measures are put forward which provides references for the same kinds of projects.
