摘要
由于诸多原因,济南站1001DG、1021-1077DG等区段存在轨道电路分路不良的现象,严重危害行车安全。高压脉冲轨道电路利用发码器产生不对称高压脉冲,电压幅值最高可达100V;能够有力地击穿钢轨表面的不良导电层。当有车占用时,二元差动继电器失磁落下,导向安全,从而彻底解决分路不良问题。
For many reasons, bad shunting of track circuit exists in many sections, such as 1001DG and 1021-1077DG, of Ji＇nan Station, seriously endangering the operation safety. High-voltage pulse track circuit generates asymmetrical high-voltage pulse by using a code generator, the voltage amplitude may up to 100V, so the poor conductive layer on the rail surface can be powerfully broken down. When the train is passing, two differential relay will be deenergized for leading to the safety side, so as to solve the problem of bad shunting thoroughly.
