摘要
Abstract
When a track circuit in the station does not meet the three-point inspection conditions,the missing release of the route a light strap is triggered as a passive protection method to ensure train operation safety.The reasons for not meeting the three-point inspection are complex,essentially due to changes in Relay GJ status that do not meet interlocking conditions,such as bad shunting,changes in Relay GJ delay characteristics,etc.Starting from two typical cases,this paper focuses on analyzing the problem of missing releasing of the route a light strap caused by non bad-shunting defects,summarizing the key points for handling such problems,in order to draw inferences and reduce the threat of such missing release to train operation safety.关键词
