矿区铁路轨道电路智能防护监控技术研究

Intelligent mine railway track circuit protection monitoring technology research

JZXC-480型交流轨道电路设备是矿区铁路行车监督列车车列的动态的重要基础设备,在使用中因锈蚀、轨面积尘等原因而导致的轮对分路不良,使轨道继电器在轨道区段内有车占用时不能可靠落下,它违背了铁路行车的"故障-导向安全"原则,是威胁铁路运输的一个重大安全隐患。通过轨道电路智能防护监控技术研究,确定研制了适合矿区铁路实际的"智能型轨道电路防护监控盒"(以下简称监控盒),以提高轨道继电器返还系数,提高了轨道电路的分路灵敏性,使轨道继电器在较高的轨道残压的情况下可靠落下,可大幅度改善轨道电路分路不良状况,保障了行车安全和行车组织效率。

Ac track circuit JZXC-480 type equipment is mine railway traffic supervision and train the important foundation of dynamic equipment, car in use due to rust, rail area of dust and other reasons caused by the wheel to shunt the bad, make the orbital relay in car track segment when not reliable, it violates the principle of ＂fault-oriented security＂ railway traffic, railway transport is a major security hidden danger.Determined by track circuit intelligent protection monitoring technology research, has been developed for the fact of the mine railway ＂intelligent track circuit protection monitoring box＂（hereinafter referred to as the control box）, in order to improve the track relay return coefficient, improves the shunt sensitivity of track circuit, make the track relay in high orbit residual pressure under the condition of reliable, can greatly improve the track circuit shunt adverse condition, ensure the running safety and operational efficiency.
