摘　　要：矿区铁路担负着运输矿产资源的重要任务。为解决矿区铁路专线生锈、行车设备年久未修引发的分路不良问题,从改造目标、改造需求、改造难点等方面出发,提出了针对矿区铁路轨道电路系统的3 V化改造的实施方案。现场实地多次多点试验结果表明:该方案符合信号专业“故障导向安全”技术要求,通过提高轨面电压击穿不良导电层,并相应地改造部分轨道电路器件,能解决分路不良的难题。选择3 V最小轨面电压、分路灵敏度0.25Ω,在最不利的情况下,受端电压为4.3 V,可靠地实现了轨道电路的分路功能。The railway in mining area undertakes the important task of transporting mineral resources. In order to solve the problem of poor shunting caused by the rust of railway dedicated lines in the mining area and the long-term unrepaired running equipment, from the aspects of transformation objectives, transformation needs and transformation difficulties, the implementation scheme of 3 V transformation for railway track circuit system in mining area was put forward. The results of many on-site multi-point tests show that the scheme meets the technical requirements of “fault oriented safety” of the signal discipline. By increasing the rail surface voltage to puncture the poor conductive layer and correspondingly transforming some track circuit devices, the problem of poor shunting can be solved. The minimum rail surface voltage of 3 V and shunting sensitivity of 0.25 Ω are selected. Under the most unfavorable conditions, the receiving terminal voltage is 4.3 V, which reliably realizes the shunting function of the track circuit.
