| 摘 要： | 基于电气几何模型,推导单线和复线铁路接触网避雷线架设高度的计算公式,由此得到避雷线架设高度与雷电击距、接触网实际参数之间的对应关系.研究表明:避雷线架设高度随着雷电流幅值的增加而减小,复线铁路的避雷线架设高度明显小于单线铁路的避雷线架设高度.采用给出的避雷线架设高度的计算公式,以广-深铁路为例,根据其不同线路形式和接触...

| Abstract: | Based on the Electric Geometry Model(EGM),the formulas for calculating the installation height of catenary ground wire for single-track and double-track railway were derived,from which the corresponding relationships between the installation height of the ground wire and the lightning striking distance as well as the actual parameters of catenary were obtained.Research shows that the installation height of the ground wire decreases with the increase of the amplitude of lightning current.The installation hei... |
