摘　　要：针对部队作战快速机动的需求,按照防雷接地的基本原理,设计了一种机动式防雷地网,并计算了地网的接地电阻,建立了土壤火花效应下水平接地体与垂直接地体组成的复合型接地网的等效电路模型.采用电磁暂态分析程序(ATP-EMTP)对地网泄放雷电流情况进行了仿真分析,仿真结果验证了该机动式防雷地网的可靠性.Directing at the demand of troops operating fast and flexibly, this paper designs a mobile lightening protection ground network in terms of the fundamentals of lightening protection grounding, calculates the grounding resistance of the ground network, and sets up an equivalent circuit model for the compound type of grounding network that is composed of horizontal earth lead and vertical earth lead under the effect of soil spark. Furthermore, by using the ATP-EMTP, the cases of leakage lightening current to the ground network is analyzed and simulated in this paper, and the simulation results prove the. reliability of the mobile lightening protection grounding network.
