Abstract

Improper design and installation of lightning protection systems can result in severe consequences for buildings and their occupants. This paper presents some common mistakes in lightning protection design and installation, including the absence of a lightning protection system for metal tanks, inadequate surge protection for field devices, improper cable management, and inadequate earthing methods. Remedial actions have been proposed to mitigate these mistakes, including the installation of a lightning protection system for metal tanks, the installation of a surge protection device (SPD) on the field devices, proper cable management and segregation of signal cables, the adequate separation distance between the electrical earth (E) chamber and the extra low-voltage earth (ELVE) chamber, and proper record of resistance value between the E and ELVE chambers. Finally, the paper emphasizes the importance of hiring qualified professionals to design and install lightning protection systems to ensure proper design and installation.

防雷设计与安装中的常见错误

防雷系统的设计和安装不当会对建筑物及其居住者造成严重后果。本文介绍了在防雷设计和安装中常见的一些错误，包括金属储罐没有防雷系统、现场设备防雷不到位、电缆管理不当、接地方法不合理等。建议采取补救措施以减轻这些错误，包括为金属储罐安装防雷系统，在现场设备上安装防雷装置(SPD)，适当的电缆管理和信号电缆隔离，电接地(E)室和特低压接地(ELVE)室之间适当的间隔距离，以及E室和ELVE室之间适当的电阻值记录。最后，本文强调了聘请合格的专业人员设计和安装防雷系统的重要性，以确保正确的设计和安装。
