现代防雷技术不断改进，为了解决当前弱电设备雷害及防护问题，采用了弱电设备外部防护与内部防护措施。其中外部防护包括避雷针的安装，将雷电中的大量的点电荷导入大地，使其保证弱电设备的安全性；内部防护主要为增设弱电装置，减少雷电对其设备的损坏。在此进行详细分析，提供可参考性的依据。%With the continuous improvement of the modern lightning protection technology, in order to solve the problem of the current weak current equipment lightning disturbance and protective, adopted the protection for weak current equipment external and internal safety measures, external safety measures including lightning rod installation, the large amount of point charge into the earth, to guarantee the safety of weak current equipment. Internal protection mainly is to add weak current device,reduce lightning damage to the equipment. The problems are detailed analyzed in order to provide reference.
