摘　　要：本文主要讨论了高压交流架空线路下人体对地感应电位和人体接触电流的算法。文中首先把人体简化等效为一个等值圆柱,用等效电荷法导出了单相架空线路下人体对地电位的计算模型。在此基础上,进一步将模型与算法推广到三相高压交流架空线路的情况。然后本文运用所推出的模型与算法计算出人接触架空线路下的导体时通过人体的电流。本文推出的模型与算法具有计算步骤简单,计算量小,便于工程运用等优势。This paper is mainly aimed at discussing the calculation method of human-earth induced voltage which is generated by AC high-voltage overhead power lines,as well as touch-current of human body.At the beginning of this paper,the human body is simply equivalent to a cylinder,and the calculation model of human-earth induced voltage generated by single phase high-voltage overhead power line is derived by Equivalent Charge Method.On basis of it,this model and calculation method are further extended to the three-phase high-voltage overhead power lines situation.Secondly,this paper applies the derived model and calculation method to calculate the current through the human body when the human body touches the conductor under overhead power lines.It has the advantages of simple calculation procedure,small calculation burden,and convenient to engineering application.
