雷电流幅值及其特性是雷电科学研究以及输电线路防雷设计的重要基础数据。利用雷电定位系统监测获取的上海地区2001—2010年地闪落雷电流幅值数据,统计分析了上海市整体区域以及崇明县(含长兴)、宝山区、嘉定区、浦东新区、市区、青浦区、闵行区、南汇区、松江区、奉贤区和金山区共11个子区域的正极性、负极性及综合雷电流幅值的累积概率分布和均值分布变化规律。在此基础上,给出了上海市整体区域以及各子区域2001—2010年落雷电流的幅值概率密度计算公式,为上海地区输电线路防雷差异化设计、改造和评估提供科学依据。
Analysis of Distribution Characteristics of Lightning Current Magnitude in Shanghai Area
Lightning current amplitude and its features are an important basis for lightning scientific research and design of lightning protection for electric transmission line.The mean amplitude distribution and cumulative probability distributions of positive and negative flash in Shanghai area and its sub-administrative regions including Chongming,Changxing,Baoshan,Pudong,the downtown,Qingpu,Minhang,Nanhui,Fengxian and Jinshan,are analyzed by using the monitoring data of lightning location system from 2001 to 2010.Based on those work,probability density functions of lightning current amplitude from 2001 to 2010 for each administrative region and Shanghai area are shown,which provide the according to design,rebuild and evaluation of differentiation technology and strategy of lightning protection for electric transmission line in Shanghai area.
