摘要:
为了明确接地装置冲击试验时回流极布置对冲击特性测试的影响,研究了回流路径对实际塔脚冲击特性的影响。测试了塔基的四种不同回流电极结构:单根电极、多根电极、环形电极、环形电极和多根电极的组合电极的冲击响应,同时与常用的单回路电极测试的结果进行了比较。研究表明:在不同的回流极结构下,测量得到不同的冲击接地电阻值和地电位升,相比单根回流极,多根回流极和环形回流极的组合可更好的地模拟雷电真实放电情况。
Abstract:
In order to find out the influence of the arrangement of the reflow electrode on the impact characteristic in the grounding device impact test, this paper studies the impact of the return path on the impact characteristics of the actual tower leg. Four different reflow electrode structures of tower foundation are tested: the shock response of a single electrode, multiple electrodes, ring electrodes, the combination electrode of ring electrodes and multiple electrodes; at the same time, they are compared with the test results of a single-loop electrode. Studies have shown that comparing the impact resistance and earth potential rise of different reflow electrodes, the combination of multiple reflow electrodes and ring reflow electrodes has a better simulation of real lightning discharge than a single reflow pole.
