| 摘 要： | 为提高综合贯通地线的利用率,以其接地阻抗及对钢轨电流的分流系数作为接地效果的评价指标,对地线半径、埋设深度、横向连线间隔和土壤电阻率与系统接地效果的关系进行了研究.结果表明,地线半径、横向连线间隔和土壤电阻率对接地阻抗和分流系数影响较大,埋设深度的影响较小.与遂渝线无砟轨道的实验结果相比,接地阻抗相差17.3%,分流系数相差11.4%. |
| 关 键 词： | 综合地线 阻抗 分流系数 钢轨电位 |

| Abstract: | In order to improve the utilization of integrated grounding wire(IGW),the inflences of its radius,buried depth,interval of transversal connections and soil resistivity on grounding effect were analyzed by taking IGW grounding impedance and shunting coefficient for rail current as the assessment indices of the grounding effect.The research result shows that the grounding impedance and the shunting coefficient are sensitive to the changes of IGW radius,interval of transversal connections and soil resistivity,... |
| Keywords: | integrated grounding wire impedance shunting coefficient rail potential |
