摘　　要：介绍了AG50系列电涌保护器(SPD)的结构、功能、技术原理、主要技术性能指标。AG50系列SPD有Ⅰ、Ⅱ、Ⅲ类,分别采用了不同的功能模块,具备直击雷、感应雷和操作过电压等电涌防护功能,可有效地保护供电、配电系统的安全。AG50系列SPD适用于不同电磁环境的供电、配电系统和不同接地的供电系统的安装要求。SPD选用时,应考虑自身的安全和保护能力。The design, function, technological principles and main technical parameters of AG50 type SPD were described. The Ⅰ, Ⅱ and Ⅲ models of AG50 SPD, using different functional blocks for protection against straight thunder, inductive thunder and switching overvoltage, can provide effective protection to power supply and distribution system. SPD of AG50 series can meet requirements for all power supply and distribution system with different electro-magnetic environments and grounding mode. Safety of itself and protection capability shall be also considered in selection of SPD.
