摘要
为解决高土壤电阻率地区牵引供电系统的接地问题，文章提出一种基于导电混凝土的接触网支柱基础自然接地方法。围绕机械强度和导电性能进行导电混凝土的配比优化，筛选出20%石墨+2.5%钢纤维的复合导电相材料；对导电混凝土接触网支柱基础自然接地方案和接地效果进行了分析，发现该方案的接地电阻降低了73.16%，将相邻的多个接触网支柱基础相连时，可满足牵引供电系统接地电阻的要求。对雷电冲击下导电混凝土支柱基础的电热特性进行了分析，发现导电混凝土接触网支柱基础在泄放雷电流时温升较小，内部温度分布均匀，不易受到结构应力的影响。文章所提基于导电混凝土的牵引供电系统接地方法，只需将施工时的浇筑材料由普通混凝土替换成导电混凝土即可，实施简单便捷，为高土壤电阻率地区电气化铁路的接地提供了一种新的方法。
Abstract
A grounding method of OCS pillar foundation based on conductive concrete was proposed to solve the grounding problem of traction power supply system in areas with high soil resistivity. The proportioning of materials for conductive concrete was optimized from two aspects: mechanical strength and conductivity
and the composite conductive material composed of 20% graphite + 2.5% steel fiber was selected. By analyzing the natural grounding scheme and effect of conductive concrete OCS pillar foundation
it was found that scheme could reduce the grounding resistance by 73.16%. If the adjacent foundations were connected
it could meet the requirements of grounding resistance of traction power supply system. The electrothermal characteristics of conductive concrete foundation under lightning impulse were analyzed
and it was found that the temperature rise of conductive concrete OCS pillar foundation was small. The internal temperature distribution was uniform
and it was not easy to be affected by structural stress. The proposed grounding method of traction power supply system based on conductive concrete only needs to replace the ordinary concrete with conductive concrete during construction
which is simple and convenient to implement. It provides a new method for the grounding of electrified railway in areas with high soil resistivity.
