对电气集中侵限绝缘检查电路设计的变更探讨

调车折返信号机接近区段为仅有一组道岔的被侵限轨道区段,由于区段长度较短,调车车列极易越过该区段后在其解锁的情况下,再由此折返而造成漏解锁,挤岔或列车、车列相撞的严重后果。这种事故已频繁发生。本文就此问题提出电路设计的变更意见,与大家共同探讨。

Discussion about Modifying the Check Circuit Design of Insulated Joint Located Within the Clearance Limit in the Case of Electric Interlocking

Approaching section of shunting turn-back signal is a section,which is equipped with only one group of switches,and because of short section length,has the insulated joint located within the clearance limit.So after a shunting train set runs over the section, which has been released,it is liable to turn back again wherefrom and makes severe consequences as release missing,switch trailing,or collision between train and train set.This kind of accident is seen frequently,The paper sets forth the opinion regarding modifying the circuit design,and the discussion with you is expected.
