style="text-indent:25px">戶外式熔斷器工作原理是：將熔絲穿入熔管內(nèi),兩端擰緊,并使熔絲位于熔管中間偏上方,上動觸頭由于熔絲拉緊的張力而垂直于熔絲管向上翹起,用絕緣拉桿將上動觸頭推入上靜觸頭內(nèi),成閉合狀態(tài)(合閘狀態(tài))并保持這一狀態(tài)，河南熔斷器廠家。當(dāng)被保護(hù)線路發(fā)生故障,故障電流使熔絲熔斷時(shí),形成電弧,消弧管在電弧高溫作用下分解出大量氣體,使管內(nèi)壓力急劇增大,氣體向外高速噴出,對電弧形成強(qiáng)有力的縱向吹弧,使電弧迅速拉長而熄滅.與此同時(shí),由于熔絲熔斷，河南熔斷器廠家,熔絲的拉力消失,使鎖緊機(jī)構(gòu)釋放,熔絲管在上靜觸頭的彈力及其自重的作用下,繞下軸翻轉(zhuǎn)跌落,形成明顯的斷開距離，河南熔斷器廠家。使電路斷開，切除故障段線路或者故障設(shè)備。關(guān)于熔斷器的知識你了解多少？河南熔斷器廠家</p><div

跌落式熔斷器在下常運(yùn)行時(shí)，熔絲管借助熔絲緊后形成閉位置。當(dāng)系統(tǒng)發(fā)生故障時(shí)，故障電流使熔絲通迅速熔斷，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，電弧被速拉長而熄滅。熔絲熔斷后，下部動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)。用絕緣桿拉開動觸頭，此時(shí)主動、靜助觸頭仍接觸，繼續(xù)用絕緣桿拉動觸頭，輔助觸頭也分離，在輔助觸頭之間產(chǎn)生電弧，電弧在滅弧罩狹縫中被拉長，同時(shí)滅弧罩產(chǎn)生氣體，在電流過零時(shí)，將電弧熄滅。
