轨道电路分路不良是困扰全路电务系统多年的老大难问题。粉尘污染、钢轨生锈等造成轨道电路区段有车占用时,轨道继电器不能落下,对行车安全构成了极大的威胁。目前,全路普遍对轨道电路采用人工除锈、压道或挂牌警示等,在技术上采用高压不对称脉冲轨道电路、计轴等解决方案,但会 Bad track circuit shunt is bothering the whole road power system for many years the problem of chronicity. Dust pollution, rail rust caused by the track circuit section of a car occupied, the track relay can not fall, driving safety posed a great threat. At present, the road generally used artificial orbital circuit rust, gushed or listed warning, technically using high voltage asymmetrical pulse track circuit, axle counting and other solutions, but will
