摘　　要：输电线路的静电感应尤其是暂态电击一直被人们普遍关注。笔者分析了输电线路引起暂态电击的原因,采用有限元分析软件建立了输电线下的人体模型和3种常见的线下感应物体模型,计算了感应电压和可能引起人体暂态电击的能量水平,指出了人体独立处于线下电场时感应电压不超过1.2kV,线下物体上的感应电压和蓄积的能量则有引起人体电击的可能性。Attention has always been paid to electrostatic induction of transmission lines,especially to transient electric shock.The cause of the transient shock induced by transmission lines is analyzed.A model of human body and three models of common objects under transmission lines are built,hence the induced voltage and the energy level which may cause the shock are calculated.The results indicate that the induced voltage on a person staying alone under transmission lines is lower than 1.2 kV,but the induced voltage and energy on the objects under the lines are possible to result in electric shock on the human body.
