摘要
光伏发电站大多地处宽阔高处,发电系统主要安装在露天状态下,且分布面积大,组件和支架都是导体,因此存在着受直接和间接雷击的危害。同时,光伏发电系统自身工作电压较低,耐压水平不高,故整个系统更易遭受雷电侵袭,造成设备毁坏、系统无法正常运行。因此,文章从光伏发电站的雷电侵袭特点出发,探析光伏发电站的内部防雷措施、外部防雷措施及防雷检测的技术要点。
Most photovoltaic power stations are located at broad heights,and the power generation system is mainly installed in the open air with a large distribution area.The components and brackets are all conductors,so there is a risk of direct and indirect lightning strikes.At the same time,the photovoltaic power generation system itself has a low working voltage and low voltage withstand level,making the entire system more susceptible to lightning attacks,causing equipment damage and system malfunction.Therefore,starting from the characteristics of lightning invasion in photovoltaic power plants,this article explores the internal lightning protection measures,external lightning protection measures,and technical key points of lightning protection detection in photovoltaic power plants.
