    • Zinc Oxide Arrester

    Zinc Oxide Arrester

    避雷器是电力系统各类电气设备(变压器、电抗器、电容器、发电机、电动机、PT、CT、断路器、接触器等)绝缘配合的基础,由避雷器的保护性能确定电力系统所有电气设备的内外绝缘指标(短时工频耐压、雷电冲击耐压和操作冲击耐压等)。 金属氧化物避雷器,俗称“氧化锌避雷器”是20世纪八十年代由美、日等国开始在国际上普及推广的新一代避雷器,是常规避雷器中最先进的产品。我国八十年代中期全面引进该项技术后,通过多年实践消化,目前各专业避雷器厂的交流避雷器性能与美、日、西欧等国的最先进产品差距并不大,真正达到了国际全部要求的产品也可以满足国际IEC标准的全部要求。 该产品核心工作元件采用以氧化锌为主的多元金属氧化物粉末烧制,具有优异的非线性状-安特性,陡波响应快,通流容量大。有间隙产品采用自吹间隙,带均压照射结构,降低了放电的分散性,冲击系数小。 复合绝缘外套的采用,顺应了国际电力产品小型化,安全化,免维护的发展趋势。高分子有机复合材料与传统的陶瓷和玻璃等无机材料相比,具有体积小、重量轻、耐污秽、免清扫、防爆防震动的优点。是集成化、模块化的中高压输变电成套设备中首选的防雷元件。
