摘　　要：本文介绍大秦线实施“V斝吞齑耙院蟛栉胝竟┑绶绞礁脑旆桨讣胺椒ā２栉胝舅┑绫畚玖帧栉搿伦┑绫?由于该站交接口较多,机车换挂,车辆转线作业频繁,加之上下行股道不均衡,不可避免地存在上下行股道混接列车的情况,如果木林—下庄供电臂上行(或下行)天窗停电,就势必影响该站的作业。为了既保证木林—茶坞及茶坞—下庄2个区间的供电设备能进行“V”型天窗作业,又不影响该站的接发列车,对该站的供电方式进行了改造,使之具有单独的停、送电功能。This paper introduces the improvement and method in Chawu Railway Station from Datong to Qinghuangdao after the implementation of V traffic break time. The power supply section of Chawu Railway Station is located in Mulin--Chawu--Xiazhuang. Because there are many interfaces with frequent work of locomotives exchanging, rolling stock turning, uneven power supply between up and down line, so it is not avoidable for the mixing up of receiving and departure of trains. It must influence the works of the station if the power in Mulin--Xiazhuang up line (down line) is off in traffic break time. In order to ensure to do the work in 'V' traffic break time for feeding section in Mulin--Chawu and Chawu--Xiazhuang two power supply sections without any influence of receiving and departure of trains at the same time, we improved the feeding mode of Chawu Railway Station which has separate function of power off and on.
