一、用途特点本公司生产的HY系列避雷器主要用于35KV及以下电压系统，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。外壳采用硅橡胶浇铸而成，运输过程中不易损坏，增大了放电距离，使用寿命大大加长。二、型号说明三、工作原理氧化锌避雷器是目前国际 的过电压保护器。由于其核心元件采用氧化锌电阻片，与传统碳化硅避雷器相比，改善了避雷器的伏安特性，提高了过电压通流能力，从而带来避雷器特性的根本变化。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，由于氧化锌电阻的非线性，流过避雷器的电流瞬间达数千安培，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。四、使用条件环境温度：不低于－40℃，不高于＋60℃。海拔高度不超过3000m，超出3000m可根据实际情况特制。电网频率：48～52Hz（50Hz系统）、58～62Hz（60Hz系统）。长期加在避雷器上的电压不能超过其额定电压。安装场所的空气中不应含化学腐蚀气体、蒸汽、爆炸性尘埃，如有，在定货时要注明。常用型号：5KA无间隙避雷器：型号额定电压（KV）持续运行电压（KV）残压（KV）方波冲击电流耐受大电流耐受陡坡冲击电流操作冲击电流标准雷电冲击HY5W-332.559.57.7910065HY5W-665.119.015.441810065HY5W-997.6528.523.12710065HY5W-121210.238.030.83610065HY5W-151512.747.538.54510065HY5W-181815.357.046.25410065HY5W-212117.066.553.96310065HY5W-242419.276.061.67210065HY5W-272721.985.569.38110065HY5W-303024.495.076.59010065HY5W-333326.8104.584.79910065HY5W-363629114.092.410810065HY5W-424234.1132.3100.11261006510KA无间隙避雷器：型号额定电压（KV）持续运行电压（KV）残压（KV）线路放电等级大电流耐受陡坡冲击电流操作冲击电流标准雷电冲击HY10W-332.559.57.79１100HY10W-665.119.015.418１100HY10W-997.6528.523.127１100HY10W-121210.238.030.836１100HY10W-151512.747.538.545１100HY10W-181815.357.046.254１100HY10W-212117.066.553.963１100HY10W-242419.276.061.672１100HY10W-272721.985.569.381１100HY10W-303024.495.076.590１100HY10W-333326.8104.584.799１100HY10W-363629114.092.4108１100HY10W-424234.1132.0100.1126１100HY10W-484839152.0126.0150１100HY10W-545443171.0139.0162１100HY10W-606048208.0160.0180１100HY10W-666652.8230.0172.0198１100主要产品选型表型号避雷器额定电压系统标称电压持续运行电压直流1mA参考电压标称放电流下残压陡波冲击残压2Ma操作通流容量使用场所KVKVKVKVKVKVKVHY1.5W-0.28/1.70.280.220.240.61.3-75低压HY1.5W-0.5/2.60.50.380.421.22.6-75HY5WS-3.8/173.8327.51719.6100配电（S）HY5WS-7.6/307.664153034.5100HY5WS-10/301068153034.5100HY5WS-12.4/5012.7106.6255057.5100HY5WS-17/50171013.6255057.5100HY5WZ-3.8/13.53.8327.213.514.5200电站（Z）HY5WZ-7.6/277.66414.42731200HY5WZ-10/27106814.42731200HY5WZ-12.7/4512.7106.6244551.8200HY5WZ-17/45171013.6244551.8200HY5WZ-42/134423523.473134154400HY5WZ-51/134513540.873134154400HY5WZ-100/26010011078145260291400,600HY10WE-100/26
