铁路贯通地线地电位分布影响因素分析

Analysis for affect factors of surface-potential gradient of railway run-through earth conductors

以综合贯通地线和不同电阻率的土壤结构作为整体进行建模,考虑综合贯通地线自身电阻率,结合有限元分析的方法,运用有限元专业分析软件ANSYS计算综合贯通地线的接地性能,分析影响综合地线在土壤中电位分布的影响因素.

The article will model the run-through earth conductors and different resistivity soil structure as a whole,according to Maxwell＇s electromagnetic theory,adopt finite element analysis method,and use finite element analysis software ANSYS for the performance parameters calculation of railway integrated grounding system performance parameters.And then the paper analyze the surface-potential gradient of railway run-through earth conductors and its affect factors.
