摘要
基于3D模拟电荷法(Charge Simulated Method,CSM),对高压线下吊车的感应电压进行了建模分析,并计算了输电线-吊车系统之间的电容值,之后系统地建立电路模型并计算人体触碰吊车后通过人体的电流.计算结果验证了模拟电荷法对输电线路下方大型物体感应电压计算的有效性,同时表明了输电线路下方的吊车对近地处电位分布具有较大影响,而且人体接触车体后产生的触电电流与人体的绝缘防护程度关系紧密,最后给出了相关施工安全的建议.
The 3D charge simulation method （CSM） is applied to modeling and analyzing the induced volt- age on a crane below high voltage transmission lines. Accordingly, the capacitance among the transmission lines-crane system is calculated; and a circuit model based on it is built in order to calculate the electric cur- rent through the human body when people touch the crane. The results of calculation verify the effective- ness of the CSM in calculating the induced voltage on large objects below transmission lines. Besides, it is shown that the crane below transmission lines perturbs the electric potential distribution in near-earth are- a; moreover, it indicates the close relationship between the short-circuited current and insulation protec- tion of human body. Finally, some advices are given for safety.
