基本原理：氧化锌避雷器是目前国际上理想的过电压保护器, 它采用了氧化锌电阻为主要原件, 与传统的碳化硅避雷器相比, 大大改善了电阻片的伏安特性, 提高了通流能力, 可以做成无间隙避雷器。因此带来了电器结构特点的根本变化。当避雷器在正常工作电压下, 流过避雷的电流仅是微安级, 当遭受过电压时, 避雷器优异的非线特性发挥了作用, 流过避雷器的电流达数千安培, 避雷器处于导通状态, 释放过电压能量, 从而防止了过电压对输变电设备的侵害。使用条件：1.环境温度不高于+40℃, 不低于-40℃2.海拔高度不超过1000m-2000m3.最大风速不超过35m/s4.地震裂度7度及以下地区5.电源频率50Yz或60Yz6.长期施加在避雷器上的工频电压不超过避雷器的持续运行电压。异常使用条件、需在订货时说明并双方协商解决。性能特点：本公司生产的0.22-110KV级各种类型的氧化锌避雷器。除各项性能符合国家标准GB11032外, 还有以下特点：1 .实配直流参考电压高于国标规定值4%以上, 有利于提高避雷器的稳定性。2 .能量耐受能力裕度大, 如10KV配电型避雷器2mA方波通流容量实际可达150A; 4/10μs大电流冲击耐受能力达65KA。3 .泄漏电流小, 0.75倍直流1mA电压下的泄漏电流通常不大于20μA,而且耐老化性能好, 长期使用稳定可靠。4 .密封结构先进可靠, 复合外套采取一次性整体模压成型。5 .产品爬电距离大, 耐污性能好。6 .可根据用户要求进行设计和生产各类有特殊要求的产品。出口避雷器技术参数：产品型号额定电压(kV)持续运行电压(kV)最大残压通流容量At0.5kA kVAt5kA kVAt5kA kV2000μS A8/20μS kA4/10μS kAHY5W-12129.6283640150565HY5W-212116.8506370150565HY5W-242419.2587280150565HY5W-303024.07290100150565HY5W-333326.47898110150565HY10W-12129.62734382001065HY10W-242419.25468762001065HY10W-303024.06784942001065交流无间隙氧化锌避雷器主要产品电气性能参数：类别避雷器型号避雷器额定电压(kV)系统标称电压(kV)持续运行电压(kV)直流1mA参考电压(不小于)(kV)0.75倍直流参考电压下漏流(不大于)(μA)陡坡冲击电流(不大于)(kV)雷电冲击电流(不大于)(kV)操作冲击残压(不大于)(kV)2mS方波通流容量(电流A、18次)4/10μS冲击电流(kV)低压H(Y)1.5W-0.28/1.300.280.220.240.6030-1.30-7525H(Y)1.5W-0.5/2.600.500.380.421.2030-2.60-7525配电(S)H(Y)5WS-5/15534.07.53017.315.012.812065H(Y)5WS-10/301068.016.03034.630.025.612065H(Y)5WS-17/50171013.625.03057.550.042.512065电站(Z)H(Y)5WZ-5/13.5534.07.23015.513.511.520065H(Y)5WZ-10/271068.014.43031.027.023.020065H(Y)5WZ-17/45171013.624.03051.845.038.320065H(Y)5WZ-51/134(130,125)513540.873.040154(150,154)134(130,125)114(112,110)40065 100H(Y)5WZ-52.7/134(130,125)52.73542.273.040400H(Y)5WZ-54/134(130,125)543543.274.040400H(Y)10WZ-100/2601001108014550299260221600100H(Y)10WZ-102/26510211081.614850305265226600100H(Y)10WZ-108/28110811086.415750332281239600100发电机(D)H(Y)5WD-4/9.5*43.153.2574010.79.57.640065H(Y)5WD-8/18.7*86.36.311.24021.018.715.040065H(Y)5WD-13/31*13.510.510.518.64034.731.025.040065H(Y)5WD-17.5/10*17.513.813.824.44044.840.032.040065H(Y)5WD-20/45*2015.815.828.04050.445.036.040065H(Y)5WD-23/51*2318.018.031.94057.251.040.840065H(Y)5WD-25/56.2*2520.020.035.44062.956.245.040065旋转电机(D)H(Y)2.5WD-4/9.5*431.53.25.73010.79.57.620065H(Y)2.5WD-8/18.7*86.36.311.23021.018.715.020065H(Y)2.5WD-13.5/31*13.510.510.518.63034.731.025.020065并联补偿电容器(R)H(Y)5WR-8/13.5534.07.240-13.510.54006565-100H(Y)5WR-10/271068.014.44027.021.0400H(Y)5WR-17/44171013.624.05046.035.0400-1200H(Y)5WR-48/134(130,125)483538.173.050-134(130,125)105400-120065-100H(Y)5WR-51/134(130,125)513540.873.050105400-120065-100H(Y)5WR-52.7/134(130,125)52.73542.273.050105400-120065-100H(Y)5WR-54/134(130,125)543543.273.050105400-120065-100变压器电抗器中性点H(Y)1.5W-55/13255110447940-13212640065H(Y)1.5W-60/1446011048854014413540065H(Y)1.5W-72/18672110581034018617440065H(Y)1.5W-73/2007311058.41054020016540065电气化铁道(T)H(Y)5WT-42/1204227.53465401381209840065H(Y)5WT-84/2408455681304027624019640065H(Y)10WT-42/1204227.53465401381209840065H(Y)10WT-84/2408455681304027624019640065线路(X)H(Y)10WX-17/60171013.625407060-40065H(Y)10WX-51/220513540.87340240220-40065H(Y)10WX-51/170513540.87340190120-40065产品参数：品牌: 任丘市迈进电器有限公司; 型号: HY5WS-17/50; 极数: 全部; 额定频率: 50（Hz）; 额定绝缘电压: 12（V）; 灭弧方式: 避雷; 机械寿命: 10（万次）; 产品认证: ISO9001-2000  电话：0317-2915139
