Abstract: The existing protection circuit with switch lying in receiving-departure track cannot meet the demand of train departure with middle switch in reverse position. Depending on the computer based interlocking, this paper puts forward a design scheme suitable for train departure with middle switch in reverse position on the basis of the existing protection circuit with switch lying in receiving-departure track. The specific design scheme includes the special design of the end of the departure route with the middle switch in the reverse position, and the design of special release and scattered circuits in relevant sections of the route. The proposed scheme has been applied to Yungang West Station of Shanxi Jinneng Holding Group Co., Ltd, and is able to meet the operation requirements of the station, with good performance during field operation.

Key words: train departure with middle switch in reverse position, logical terminal, special release

摘要： 原有到发线出岔电路不能满足中岔反位发车作业需求,针对此种情况，基于计算机联锁，在原有到发线出岔电路的基础上，提出适用于中岔反位发车作业场景的设计方案。具体的设计方案包含中岔反位发车进路终端的特殊设计及进路中相关区段的特殊解锁以及零散电路的设计。该方案应用于山西晋能控股的云冈西站，满足车站的作业需求，现场运行状况良好。
