摘要/Abstract

摘要： 基于人工触发闪电T179的10次回击过程，分析了雷电流作用下2个独立地网的相互作用及转移地电位特征，并通过冲击低压电源浪涌保护器（SPD），计算和评估了转移地电位冲击SPD的能量。结果发现，地网隔离40 m距离产生的转移电位（TGP）电压峰值比较大，平均值可达–10.9 kV。TGP电压峰值与触发闪电电流峰值之间呈现非常好的正相关性，拟合优度R²达到0.97。冲击SPD的能量比较小，10次回击平均值为1.5 J，电子设备加装SPD浪涌保护器是相对安全。

Abstract: Based on 10 return strokes of one artificially triggered lightning T179, the interaction of two independent ground networks and the characteristics of transferred ground potential(TGP) under the action of lightning current are analyzed, and the energy of SPD impacted by TGP is calculated and evaluated through the impulse low-voltage power surge protector (SPD). The results show that the generated peak TGP voltage at the ground network 40 m away is relatively large, reaching –10.9 kV on average. There is a very good positive correlation between the peak TGP voltage and the peak triggered lightning current with the correlation coefficient R² reaching 0.97. The energy of impacting SPD is relatively small, with the average value of 10 return strokes being 1.5 J. It is therefore very safe to install SPD surge protector for electronic equipment.

Key words: artificially triggered lightning, independent ground grid, transferred ground potential, SPD residual voltage, ground wire current
