【摘要】：雷电流是描述闪电放电最重要的物理量,对于雷电防护相关研究意义重大,因此,雷电流测量一直是雷电研究领域的基础性工作。为了获得自然雷电流全波波形,在南京第一高楼紫峰大厦(约450 m)楼顶的避雷针处安装了一套雷电流全波测量系统,用于长期检测雷击建筑物回击电流和建筑物上行先导电流。该系统包含两套子系统,分别由雷电流传感器、数据传输系统、数据采集系统、远程控制系统构成,能够同时测量回击电流和建筑物上行先导电流,对国内特别是华东地区高塔自然雷电流研究具有重大意义。首先对所安装的雷电流测量系统进行了介绍,对测得的两组上行先导电流波形进行了全面分析,得出高建筑物上行先导电流波形的相关特征。
[Abstract]:Lightning current is the most important physical quantity to describe the lightning discharge, which is of great significance to the research of lightning protection. Therefore, the measurement of lightning current is always the basic work in the field of lightning research. In order to obtain the full wave waveform of natural lightning current, a full wave measuring system of lightning current is installed at the lightning arrester on the roof of Zifeng Building, No. 1 building in Nanjing, which is used to detect the lightning stroke current of buildings and the upstream lead current of buildings for a long time. The system consists of two subsystems, which are lightning current sensor, data transmission system, data acquisition system and remote control system. It is of great significance to study the natural lightning current of tower in China, especially in East China. First, the installed lightning current measurement system is introduced, and the two sets of uplink current waveforms are analyzed comprehensively, and the relevant characteristics of the uplink current waveforms of high buildings are obtained.
