10kV跌落式熔斷器適合于環(huán)境空氣無導(dǎo)電粉塵、無腐蝕性氣體及易燃、易爆等危險性環(huán)境，年度溫差變比在±40℃以內(nèi)的戶外場所。其選擇是按照額定電壓和額定電流兩項參數(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，對所選定的熔斷器進(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，造成在熔體熔斷時難以滅弧，引起熔管燒毀，等***。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，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)，同時要注意到它的額定斷開容量上限值和下限值。

style="text-indent:25px">跌落式熔斷器的安裝和運行維護(hù)：跌落式熔斷器瓷件應(yīng)良好，熔絲管不應(yīng)有吸潮膨脹、彎曲變形現(xiàn)象。熔絲管上下觸頭的中心線與熔絲管軸線應(yīng)在同一平面內(nèi)，不得扭歪。跌落式熔斷器應(yīng)安裝牢固、排列整齊，不得左右轉(zhuǎn)動，10kV跌落式熔斷器相間水平距離不應(yīng)小于0.5m。為便于操作和熔絲熔斷時自跌，使熔絲管軸線有一定傾斜度，瓷座軸線與地面垂線的夾角一般為20°~30°。分、合閘操作應(yīng)靈活、可靠，接觸緊密。合閘前調(diào)整上下觸頭應(yīng)有一定的壓縮行程。在運行中，跌落式熔斷器熔絲熔斷3~4次后，應(yīng)檢查熔絲管內(nèi)徑是否增大，如果增大2~3mm,則應(yīng)考慮更換新的熔絲管。在運行中如發(fā)現(xiàn)跌落式熔斷器分、合閘不靈活、則應(yīng)立即檢修調(diào)整。熔斷器的維護(hù)方面我們應(yīng)該注意什么？廣州跌落式熔斷器供應(yīng)商</p><p style="text-indent:25px">熔斷器的安裝應(yīng)該注意什么？廣州跌落式熔斷器供應(yīng)商</p><p> 跌落式熔斷器在下常運行時，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，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。用絕緣桿拉開動觸頭，此時主動、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，同時滅弧罩產(chǎn)生氣體，在電流過零時，將電弧熄滅。
