摘要
在无法安装轨道电路的部分区段,采用轨道电路原理的断轨检测技术是一种有效途径.在分析ZPW-2000A等型号轨道电路原理的基础上,提出了一种轨道断轨检测方法,为中央发送信号,两端电流接受式的无绝缘轨道电路.结果表明:安装在4条钢轨上的电流传感器及其组合信号能够表征钢轨是否发生断轨.该方法受环境因素影响小、抗干扰能力强、设备简单,具有较高的推广应用价值.
It is an effective way to employ the method of broken rail detection in some railway sections without a track circuits. Based on the analysis of track circuit principle of ZPW - 2000A model, a broken rail detection method is proposed, and its essence is centre-fed double-sided current-received without insulation track circuit. Through analysis, the four rail combination of current sensor and its signal can show whether rail break or not. This method has strong anti-interference ability, the advantages of simple equipment, higher application value.
