    跌落式熔斷器及拉負(fù)荷跌落式熔斷器是戶外高壓保護(hù)電器。它裝置在配電變壓器高壓側(cè)或配電線支干線路上、用作變壓器和線路的短路、過載保護(hù)及分、合負(fù)荷電流。跌落式熔斷器由絕緣支架和熔絲管二部分組成,靜觸頭安裝在絕緣支架兩端,動(dòng)觸頭安裝在熔絲管兩端,熔絲管由內(nèi)層的消弧管和外層的酚醛紙管或環(huán)氧玻璃布管組成。拉負(fù)荷跌落式熔斷器增強(qiáng)彈性輔助觸頭及滅弧罩,用以分,合負(fù)荷電流。
    ??? 跌落式熔斷器在正常運(yùn)行時(shí),熔絲管借助熔絲張緊后形成閉合位置。當(dāng)系統(tǒng)發(fā)生故障時(shí),故障電流時(shí)熔絲迅速熔斷,并形成電弧,消弧管受電弧灼熱,分解出大量的氣體,使館內(nèi)形成很高壓力,并沿管道形成縱吹,電弧被迅速拉長而熄滅。熔絲熔斷后,下部動(dòng)觸頭失去張力二下翻,鎖緊機(jī)械,釋放熔絲管,熔絲管跌落,形成明顯的開斷位置。當(dāng)需要拉負(fù)荷時(shí),用絕緣桿拉開動(dòng)觸頭,此時(shí)主動(dòng)、靜動(dòng)觸頭仍然接觸,繼續(xù)用絕緣桿拉動(dòng)觸頭,輔助觸頭也分離,在輔助觸頭之間產(chǎn)生電弧,電弧在滅罩狹縫中被拉長,同時(shí)滅弧罩產(chǎn)生氣體,在電流過零時(shí),將電弧熄滅。
