发生雷击故障时,接地体起到泄放故障电流的作用。由于雷电流幅值与瞬时频率均随注入时间快速变化,在雷电流作用下注流点附近土壤电气参数同时呈现时变性和频变性,忽略土壤的时变性和频变性会给接地体的冲击阻抗计算带来误差。针对土壤的频变性,通过希尔伯特黄变换对雷电流作时频域分解,用Viascro-Alipio土壤频变公式对土壤电阻率、介电常数等频变参数进行修正;针对土壤的时变性,将接地体分段,计算各段随时间变化的火花放电区域等效半径,建立了考虑土壤时变性和频变性的接地体暂态模型,并与文献真型试验结果对比验证其有效性。

为实现线路避雷器的带电拆换,本研究设计了一种基于磁吸力的电气连接方式,仿真计算了金属连接线在短路电流冲击和雷电流冲击下的温升和电动力,给出了连接线截面积和磁吸插头磁吸力的选择。温升仿真表明:极限条件下的短路电流会使连接线的温升急剧升高,选择截面积为25mm2及以上的连接线能耐受短路电流的冲击,而雷电流冲击不会使连接线发生烧蚀,4/10μs、65kA雷电流作用下的最大温升为2.26℃,100kA雷电流作用下的最大温升为5.35℃。电动力仿真表明:连接线受到的电动力与与短路电流的平方呈正相关 ...
