地铁折返站道岔失表故障处置

地铁在正常运营过程中,除折返站外,其余站台均采用道岔定位通过,不涉及道岔的来回转动,而折返站的道岔在运营过程中不断进行定反位转换,故而出现道岔失表故障直接影响地铁正常运营。该文对折返站各类道岔的定反位失表情况进行逐一分析,总结出不同故障情况下的故障处置,降低道岔故障对地铁运营组织的不利影响,最大程度满足乘客出行需要。

In the normal operation of the subway,except for the return station,the other platforms use turnout positioning,which does not involve the back and forth rotation of the turnout,while the turnout of the return station is constantly converted in the course of operation.Therefore,the failure of the turnout table directly affects the normal operation of the subway.This paper analyzes the position loss table of all kinds of turnouts in the return station one by one,and summarizes the fault treatment under different fault conditions,so as to reduce the adverse impact of the turnout fault on the subway operation organization and meet the passenger travel needs to the maximum extent.
