    • Zinc Oxide Arrester

    Zinc Oxide Arrester

    避雷器是電力系統(tǒng)各類電氣設(shè)備(變壓器、電抗器、電容器、發(fā)電機(jī)、電動(dòng)機(jī)、PT、CT、斷路器、接觸器等)絕緣配合的基礎(chǔ),由避雷器的保護(hù)性能確定電力系統(tǒng)所有電氣設(shè)備的內(nèi)外絕緣指標(biāo)(短時(shí)工頻耐壓、雷電沖擊耐壓和操作沖擊耐壓等)。 金屬氧化物避雷器,俗稱“氧化鋅避雷器”是20世紀(jì)八十年代由美、日等國開始在國際上普及推廣的新一代避雷器,是常規(guī)避雷器中最先進(jìn)的產(chǎn)品。我國八十年代中期全面引進(jìn)該項(xiàng)技術(shù)后,通過多年實(shí)踐消化,目前各專業(yè)避雷器廠的交流避雷器性能與美、日、西歐等國的最先進(jìn)產(chǎn)品差距并不大,真正達(dá)到了國際全部要求的產(chǎn)品也可以滿足國際IEC標(biāo)準(zhǔn)的全部要求。 該產(chǎn)品核心工作元件采用以氧化鋅為主的多元金屬氧化物粉末燒制,具有優(yōu)異的非線性狀-安特性,陡波響應(yīng)快,通流容量大。有間隙產(chǎn)品采用自吹間隙,帶均壓照射結(jié)構(gòu),降低了放電的分散性,沖擊系數(shù)小。 復(fù)合絕緣外套的采用,順應(yīng)了國際電力產(chǎn)品小型化,安全化,免維護(hù)的發(fā)展趨勢(shì)。高分子有機(jī)復(fù)合材料與傳統(tǒng)的陶瓷和玻璃等無機(jī)材料相比,具有體積小、重量輕、耐污穢、免清掃、防爆防震動(dòng)的優(yōu)點(diǎn)。是集成化、模塊化的中高壓輸變電成套設(shè)備中首選的防雷元件。
