摘　　要：通过对各种道岔控制电路的对比分析,探讨了一例直流转辙机多机牵引道岔不能正常启动故障的原因,并提出增设切断复示继电器的方式,解决了切断继电器电容放电缓放时间不足的问题,试验结果也验证了该方法安全有效。Through analyzing each kind of turnout control circuits comparatively, the author ex- plores the fault reason why a DC switch machine＇s multiple traction turnout is unable to startup normally. A method of adding more on-off repeating relays is proposed to address the insufficient release time problem of the capacitors in the on-off repeating relays. The experimental results also validate the effectiveness of the method.
