style="text-indent:25px">跌落式熔斷器適用于環(huán)境空氣無導(dǎo)電粉塵、無腐蝕性氣體及易燃、易爆等危險(xiǎn)性環(huán)境，年度溫差變比在±40℃以內(nèi)的戶外場(chǎng)所。其選擇是按照額定電壓和額定電流兩項(xiàng)參數(shù)進(jìn)行，也就是熔斷器的額定電壓需要與被保護(hù)設(shè)備(線路)的額定電壓相匹配。熔斷器具的額定電流應(yīng)大于或等于熔體的額定電流。而熔體的額定電流可選為額定負(fù)荷電流的1.5～2倍。此外，應(yīng)按被保護(hù)系統(tǒng)三相短路容量，對(duì)所選定的跌落式熔斷器進(jìn)行校核。保證被保護(hù)系統(tǒng)三相短路容量小于熔斷器額定斷開容量的上限，但需要大于額定斷開容量的下限。若熔斷器的額定斷開容量(一般是指其上限)過大，很可能使被保護(hù)系統(tǒng)三相短路容量小于熔斷器額定斷開容量的下限，造成在熔體熔斷時(shí)難以滅弧，引起熔管燒毀，等狀況。目前，一些供電單位仍處于農(nóng)網(wǎng)改造高峰，在選用該類熔斷器時(shí)，需要嚴(yán)把產(chǎn)品質(zhì)量關(guān)，保護(hù)合格的設(shè)備入網(wǎng)，同時(shí)要注意到它的額定斷開容量上限值和下限值。</p><p> 跌落式熔斷器由絕緣支架和熔絲管兩大部分組成，靜觸頭安裝在絕緣支架的兩端，動(dòng)觸頭安裝在熔絲管的兩端，熔絲管由內(nèi)層的消弧管和外層環(huán)氧玻璃管組成。拉負(fù)荷跌落式熔斷器增加彈性輔助頭及滅弧罩，用以分、合負(fù)荷電流。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(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，電弧在滅弧罩狹縫中被拉長(zhǎng)，同時(shí)滅弧罩產(chǎn)生氣體，在電流過零時(shí)，將電弧熄滅。

戶外式熔斷器，用來保護(hù)10kV電力變壓器和電力線路。由固定支持部分、活動(dòng)熔管及熔絲組成，固定支持部分為瓷或合成絕緣體。其工作原理是：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(dòng)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(dòng)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)。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(duì)電弧形成強(qiáng)有力的縱向吹弧,使電弧迅速拉長(zhǎng)而熄滅.與此同時(shí),由于熔絲熔斷,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。使電路斷開，切除故障段線路或者故障設(shè)備。
