| 摘 要： | 分析电气化铁道贯通地线引起的地电位升,建立贯通地线入地电流在周围引起地电位升的模型,推导贯通地线电流引起的地电位升的公式。根据不同的土壤电阻率和贯通地线上电流的大小,计算与贯通地线不同距离时的地电位升,对地下金属管线的布置及接地点的选取具有一定的参考作用。

| Abstract: | By analyzing ground potential rise caused by the connecting ground wire of electrified railway,we established a model of ground potential rise induced the in-earth current in connecting ground wire and derive the formula of ground potential rise caused by the current in connecting ground wire.According to different ground resistivity and different injection current,ground potential rise could be calculated by the distance from ground wire in the formula,which offers a valuable guide about the layout of unde... |
