摘　　要：为探讨高压输电线路下特殊地形的电场分布问题,利用Ansoft Maxwell软件建立了带地线的水平排列500 k V输电线路模型。分析了各种可能存在的特殊地形所对应的数学模型下电场分布特性,结果表明,最大场强值与地表面的曲面程度很有关系,曲面所表示的数学模型不同其电场值相应也会有所不同,其走廊宽度也发生了变化。To explore the electric field distribution problem of special terrain under the high-voltage transmission lines, the software Ansoft Maxwell was used to establish a 500 kV transmission line model horizontally aligned with the ground. This paper analyzed the electric field distribution characteristics of a variety of special terrain that may exist a corresponding mathematical model. The result shows that the maximum electric field density is much related to cambering degree of the ground surface, the mathematical model of camber is corresponding to the electric field value and its aisle width.
