| 摘 要： | 以钢轨电位的降低程度为评价综合接地效果的指标, 分析了钢轨电位与综合地线接地阻抗和分流系数的关系, 开发了综合接地效果评价系统, 研究了影响综合地线接地阻抗和分流系数的主要因素, 对比了综合接地效果评价系统的理论结果与现场测试结果。分析结果表明: 钢轨电位随着综合地线接地阻抗的增大而增大, 随着分流系数的增大而减小; 综合地线的选材、土壤电阻率及横向连接距离对接地阻抗和分流系数有较大影响, 而埋设深度对其影响较小; 接地电阻、分流系数的理论值和测试结果差异分别为18%、5.62%。可见, 系统的计算误差较小, 可用于高速铁路综合接地系统的设计与施工。

| Abstract: | The decreasing degree of rail potential was taken as a standard for evaluating integrated grounding effectiveness.The relationship among rail potential,integrated grounding line impedance and shunt coefficient was analyzed.The integrated grounding effectiveness evaluating system(IGEES) was developed,and the main influence factors of integrated grounding line impedance and shunt coefficient were studied.The theoretical result and measurement result of IGEES were compared.Analysis result shows that rail poten... |
