| 摘 要： | 为了研究不同形状、不同材质的避雷针接闪体的引雷性能,采用雷云板模拟雷云对装有防绕击避雷针的地线放电,统计雷云板对防绕击避雷针的击闪概率,对比分析了不同结构、不同材料防绕击避雷针的接闪性能。试验表明,针形铜避雷针闪络率较环形铜避雷针接闪率更高,引雷效果更优,而针形铜避雷针和针形钢避雷针的接闪性能一致。研究结论对线路雷电绕击的实验室模拟方法以及防绕击措施的改进研究均有参考价值。

| Abstract: | In order to study the lightning attracting performances of lightning rods with different structures and materials,and simulating the lightning strike from thundercloud to the grounding line of overhead transmission lines through the flashover from the thundercloud-simulating plate to the lightning rod against shielding failure,this paper counts the rate of flashovers,contrasts the flashover performances of lightning rods with different structures and materials.The simulations show that the flashover rate of... |
