| 摘 要： | 通过对接口电路的分析可知,当电缆芯线混线时电路存在短路紧急停车按钮的安全隐患,提出电源分缆设计的方案;同时针对地铁的每个轨旁设备采用独缆设计,过多使用维修电源及电话电缆芯线的实际情况,提出维修电源与电话线贯通设置的方案。

| Abstract: | Through the analysis of interface circuits,it is found that the circuits may cause hidden trouble of shorting the emergency stop button circuit when crossed wires are used,so a design scheme of using separated cables for the power supply is proposed.Meanwhile,considering the actual condition of using large numbers of maintenance power supply and telephone cable wires because of the design of using an independent cable for each wayside equipment,a scheme of setting a through cable for the maintenance power supply and telephone cables is put forward. |
