一、基本原理
氧化锌避雷器是目前国际最先进的过电压保护器。由于其核心元件电阻片采用氧化锌及多种金属氧化物制作、与传统碳化硅避雷器相比，大大改善了电阻片伏安特性，提高了电阻片的通流能力，从而带来避雷器特征的根本变化。
当避雷器在正常工作电压下，流过避雷器的电流仅有微安级，当遭受过电压时，避雷器优异的非线性伏安特性发挥作用，流过避雷器的电流瞬间增大到数千安培，避雷器处于导通状态，释放过电压能量，从而有效地限制了过电压对输变电设备的侵害。
二、用途特点
氧化锌避雷器用于保护交流电力系统的电气设备免遭大气过电压和操作过电压损坏。
三、使用条件
环境温度不高于+40℃，不低于-40℃；
海拔高度不超过1000m(高原地区应在订货时注明); 电源的频率不小于48Hz,不超过62Hz;
长期施加在避雷器上工频电压应不超过避雷持续运行电压；
最大风速不超过35m/s;
地震烈度7度及以下地区
污秽地区要注明。
四、技术性能
产品性能符合GB11032-2000(eqvIEC60099-4)强制性国家标准技术要求。主要电气性能参见表。
