摘　　要：为查明引起人体暂态电击的根本原因并找出有效的防止措施,利用电磁暂态软件EMTP-ATP建立了某500kV输电线路下方近地面长导体的感应电压的分析模型,着重分析了近地面长导体的电磁感应电压,并对比了实测电压值与计算电压值。结果表明,近地面长导体的电磁感应电压可忽略,近地面长导体良好接地可有效避免人体暂态电击。In order to find out the cause of transient shock and the effective measures to prevent it, the electromagnet- ic transient software EMTP-ATP is used to build a model for analysis of the induced voltage of long conductors near the ground under 500kV transmission lines. And then it emphatically analyzes the electromagnetic induction voltage of the conductors. Combined with measurements of the electromagnetic induction voltage of a line under the transmission lines, the results show that the electromagnetic induction voltage of long conductor near the ground can be ignored and it is ef- fective way for the human body to avoid the transient shock that making a long conductor is close to the grounding.
