供应避雷器

moa是当今最先进的过电压保护电器。由于zno阀片是具有优异的非线性和良好的陡波响应，用其组装的避雷器可将过电压限制在较低水平，从而对被保护设备提供可靠的保护。复合外套无间隙氧化锌避雷器（以下简称hmoa）较瓷moa更具有耐污性、抗老化性、防爆性、抗紫外线能力强、体积小、重量轻等优点。可缩小设备安装面积、改善外部污秽及周围环境条件对其的影响。日新电气经多方调研，采用先进科研单位的阀片元件，及高性能的复合外套材料生产的hmoa产品，确保产品性能的可靠性。主要技术参数及外型尺寸使用场所型号系统（电机）额定电压（kv）避雷器额定电压（kv）避雷器待续运行电压直流参考电压1ma下不小于（kv）最大残压峰植2ms方拨电流辐植(a)8/20us标准放电电流8/20us（kv）30/60us操作冲击8/20us（kv）陡波（kv）配电hy1.5-0.28/1.3hy1.5w-0.5/2.6hy5ws-10/30hy5ws-17/501.220.386100.280.510170.240.42813.60.61.210251.32.6305025.645.234.657.5307575100电站hy5wz-5/13.5hy5wz-10/27hy5wz-17/453610510174813.67.514.42413.5274511.52338.315.53151.8150旋转电机hy2.5wd-4/9.5hy2.5wd-8/19hy2.5wd-13.5/31hy5wd-17.5/40hy5wd-20/453.356.310.513.815.754813.517.5203.26.310.513.815.85.711.218.624.4289.518.73140457.61525323610.72134.744.850.4200电机中性点hy1.5w-2.4/6hy1.5w-4.8/12hy1.5w-8/193.156.310.52.44.881.93.86.43.46.811.46121951013.9200电容器hy5wr-5/13.5hy5wr-10/27.03610510174813.67.214.42413.5274610.52135400(600)电气化轨道hy5wt-42/12027.542346812098138400电力机车hy100wj-42/10527.54230581059811840035kv电站hy5wz-42/134hy5wz-51/1343535425123.440.8737313413411411415415415066kv电站hy5w-90/224hy5w-90/2356666909072.572.5130.0130.0224.0224.0190.0139.0258.0258.0400600110kv电站hy5w1-100/260hy5w1-102/266hy5w1-108/28111011011010010210878.079.684.0145.0148.0157.0260.0266.0281.0221.0236.0239.0229.0305.0323.0400400400220kvhy10w5-200/520hy10w5-204/530hy10w5-216/562220220220200204216146146146290296305520530562442450478582592628?
