摘要

为了更有效地研究电力线路杆塔在不同地形下防雷性能的差异性

笔者针对珠三角地区中的杆塔在3种不同地形下受雷击次数分布差异性问题进行分析。首先建立区域雷击统计模型

研究统计区域雷击次数的方法。然后基于雷电定位系统

对珠三角地区三种地形上10年落雷情况进行统计分析

得出电力杆塔在山区受雷击次数略高于平原建筑区

平原建筑区上的杆塔虽受高层建筑屏蔽保护作用

不易受雷击

但杆塔所处区域受雷击次数高于平原植被区。经过统计得出平原建筑落雷次数增长率明显增大

而山区与平原植被区落雷次数增长率呈下降趋势。最后利用电场仿真软件仿真坐落在3种地形上杆塔周围的电场分布趋势

验证统计出区域雷击次数规律的合理性。

Abstract

In order to more effectively understand the difference among protection performances of the power towers in different terrains

the lightning frequency distributions on the power towers in three different terrains in the Pearl River Delta is analyzed.A statistical model of regional lightning is established to obtain lightning data.The lightning distribution of 10 years in the three terrains in the Pearl River Delta is statistically analyzed based on the lightning location system.The results show that the frequency of lightning stroke in mountain terrain is slightly higher than that in plain construction zone;though the towers in plain construction zone are protected by the near tall buildings

the number of lightning in this region is larger than the number in plain vegetation zone.The statistics indicate that the growth rate of the lightning number increases significantly in plain construction zone

but decreases in either mountain zone or plain vegetation zone.Moreover

a software for electric field simulation is used to analyze the field distributions around the towers in the three terrains

and the result verifies the reasonability of the proposed statistical method.
