Method for eliminating stray current of track system
The invention discloses a method for eliminating stray current of a track system, which comprises the following steps of: S1, setting the distance between two substations in the track system to be 2-8 kilometers; s2, a drainage net is arranged in the concrete track bed, a positive temperature coefficient material is arranged in the middle of longitudinal steel bars in the drainage net, and a heater is arranged on the outer side of the positive temperature coefficient material; and S3, a plurality of sensors are arranged between the buried pipeline and the drainage net, the current value of the stray current is transmitted to a monitoring system, and the monitored value is transmitted to a microcomputer management system. The current drainage net is connected with the substation through the grounding wire, so that stray current is prevented from generating interference in a track and a signal circuit and damaging equipment. By arranging a plurality of sensors, when the monitored stray current value is greater than a threshold value, the heating module is used for heating the positive temperature coefficient material, increasing the resistance value of the current drainage net, improving the grounding effect, reducing the flowing of the stray current, and eliminating the current value of the stray current to a certain extent.
本发明公开了一种消除轨道系统杂散电流的方法，包括：S1、将轨道系统中，两个变电所之间的距离设置在2～8公里；S2、在混凝土道床中设置排流网，排流网中纵向钢筋的中部设置正温度系数材料，且在正温度系数材料外侧设置加热器；S3、在埋地管道与排流网之间设置若干传感器，将杂散电流的电流值传输到监测系统，并将监测到的数值传输到微机管理系统。通过设置排流网，与变电所通过接地线连接在一起，防止杂散电流在轨道和信号电路中产生干扰和损坏设备。通过设置若干传感器，当监测到的杂散电流值大于阈值时，通过加热模块对正温度系数材料加热，增加排流网的电阻值，提高接地效果，减少杂散电流的流动，并在一定程度上消除杂散电流的电流值。
