摘　　要：为提升铁路行车安全与运输效益,解决神朔铁路既有地面控制带电自动过分相设备开关寿命低、故障率高且随机性突出等问题,神朔铁路成功研制出智能电分相试验并投入使用。通过电子开关晶闸管替代地面控制带电自动过分相应用的真空断路器,利用轨道计轴探测系统,实现整体设备检测精确、寿命长、故障率低、分合闸的时间短且无电压电流冲击,列车可以无感知、无牵引力损失过分相。In order to improve railway operation safety and transportation efficiency,and solve the problems of low switch service life,high failure rate,and obvious randomness of the existing ground controlled live automatic neutral-section passing equipment of Shenmu-Shuozhou Railway,the intelligent neutral section test has been successfully developed and put into use.It uses electronic switch thyristor instead of the vacuum circuit breaker for the ground control live automatic neutral-section passing application,and uses rail axle counter detection system to realize the overall equipment detection accuracy,long service life,low failure rate,short switching-off and switching-on time with no voltage and current impact,so that the train can pass the neutral section without sensing and traction loss.
