| 摘 要： | 为防止对雷击输配电杆塔后，输配电杆塔附近的鱼塘中出现大量死鱼现象，对该现象的机理用有限元软件仿真的方法分析研究。研究表明，导致鱼死亡的原因是鱼遭受了雷电入地电流的电击；针对珠三角地区土壤电阻率较低的具体情况，提出了使用向背离鱼塘方向使用水平接地极，向背离鱼塘方向迁移接地体，以及在接地极与鱼塘之间设置挡板的方案；通过有限... |

| Abstract: | The mechanism of mass mortality of fish in a fishpond,which results from the lightning current of transmission tower nearby,is analyzed.It is revealed that the death of fish is caused by the lightning current from the transmission tower.Based on the condition of low resistivity of the soil in the Pearl River Delta Region,three measures are proposed,namely,using horizontal earth electrode outward from the fishpond,moving the grounding electrode outward from the fishpond,and placing an insulating barrier betw... |
