摘　　要：电涌是危害电力系统安全运行的主要因素之一,石化行业多采用安装电涌保护器的方法来抑制低压配电系统电路中产生的电涌,结合石化工程项目应用实例阐述了如何在石化低压配电系统中选择和安装布置电涌保护器。Electric surge is one of main factors harming safe operation of power system. In petrochemical industry, SPD often is used for depressing electric surge occurred in low voltage electric distribution system. In this article, combined with practical example in petrochemical engineering project, selection, arrangement and installation of SPD in low voltage electric distribution system were depicted.
