关于对郑州北上行驼峰接收不到进路命令的分析与处理

Analysis and I kindling of Failure to Receiving Route Command in Upward Hump of North Zhengzhou Marshalling Yard

分析了郑州北上行驼峰接收不到进路命令的原因,提出7024驼峰自动集中使用时间过长,动作继电器的回路电阻明显变大,对有关继电器的动作配合要求提高,指出再处理此类故障时,不但要精通电路原理,而且还要特别重视观察继电器的动作状态。

Through analyzing the causes of the upward hump failing to receive routing command at Zhengzhou North marshalling yard, it is pointed out that auto-concentration of 7024 hump occupy too long time and the loop resistance of motion relay grow bigger obviously so as to require higher level of collaboration of relevant relays in motion. Thus, command of the working principle of the circuit the relays. the maintenance engineers should not only have a good but also attach importance to observe the moving status of
