驼峰分路道岔是驼峰场溜放及调车作业的关键设备,其控制电路的准确性、稳定性对驼峰场安全作业尤其重要。近年来,铁道部建设管理司、铁道部运输局根据驼峰分路道岔控制电路在全国各个驼峰场的使用情况,针对控制电路存在的不安全因素,对修改方案进行了技术审查,修改后的控制电路 Camel sub-turnouts are the key equipment for hump peak operation and shunting operations. The accuracy and stability of the control circuit are particularly important for the hump peak operation. In recent years, the Ministry of Railways Construction Management Division, the Ministry of Railways Transport Bureau according to hump sub-turnout control circuit in the country each hump field usage, control circuit for the existence of unsafe factors, the revised program for technical review of the revised control Circuit
