2、斷器增加彈陛輔助觸頭及滅弧罩，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)，故障電流使熔絲迅速熔斷，并形成電弧，消弧管受電弧灼熱，分解出大量的氣體，使管內(nèi)形成很高壓力，并沿管道形成縱吹，電弧被迅速拉長(zhǎng)而熄滅。熔絲熔斷后，下部動(dòng)觸頭失去張力而下翻，鎖緊機(jī)構(gòu)釋放熔絲管，熔絲管跌落，形成明顯的開斷位置。當(dāng)需要要拉負(fù)荷時(shí)，用絕緣桿拉開動(dòng)觸頭，此時(shí)主動(dòng)、靜助觸頭仍然接觸，繼續(xù)用絕緣桿拉動(dòng)觸頭，輔

3、助觸頭也分離，在輔助觸頭之間產(chǎn)生電弧，電弧在滅弧罩狹縫中被拉長(zhǎng)，同時(shí)滅弧罩產(chǎn)生氣體，在電流過(guò)零時(shí)，將電弧熄滅。outfusecutoutloadswitchingfusecutoutareofoutdousedhighvoltageprotectivedevice.Tobeconnectewithincomingfeederofdistributiontransfmerdistributionlinesitmainlyprotectda
