        產(chǎn)品介紹
        避雷器是電力系統(tǒng)各類電氣設(shè)備(變壓器、電抗器、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)。
        ??? 金屬氧化物避雷器是20世紀(jì)八十年代由美、日等國(guó)開始在國(guó)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(guó)八十年代中期全面引進(jìn)該項(xiàng)技術(shù)后,通過(guò)多年實(shí)踐消化,目前各專業(yè)避雷器廠產(chǎn)品性能與美、日、西歐等國(guó)的最先進(jìn)產(chǎn)品差距并不大,真正達(dá)到了國(guó)際全部要求的產(chǎn)品也可以滿足國(guó)際IEC標(biāo)準(zhǔn)的全部要求。

        ??? 該產(chǎn)品的核心工作元件采用以氧化鋅為主的多元素金屬氧化物粉末燒制,具有優(yōu)異的非線性伏-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(guó)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(wú)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。
        用途及執(zhí)行標(biāo)準(zhǔn):
        ????本產(chǎn)品使用于交流220kV及以下發(fā)電、輸電、變電、配電系統(tǒng),用于將雷電和系統(tǒng)內(nèi)部操作過(guò)壓電的幅值限制到規(guī)定的水平,是整個(gè)系統(tǒng)絕緣配合的基礎(chǔ)設(shè)備。同時(shí),本產(chǎn)品不能用于限制諧振過(guò)電壓,系統(tǒng)消諧需要采用其它方式。
        ??? 本產(chǎn)品型號(hào)按JB/T8459-1996《避雷器產(chǎn)品型號(hào)編制方法》規(guī)定進(jìn)行編制,無(wú)間隙產(chǎn)品執(zhí)行GB11032-2000《交流無(wú)間隙金屬氧化物避雷器》標(biāo)準(zhǔn);有間隙產(chǎn)品執(zhí)行JB/T9672-2005《有串聯(lián)間隙金屬氧化物避雷器》標(biāo)準(zhǔn)。對(duì)以上標(biāo)準(zhǔn)中未明確定義的重要參數(shù)及配置方式,按DL/T620-1997《交流電氣裝置的過(guò)電壓保護(hù)和絕緣配合》的要求修正執(zhí)行。
