熔斷器有個(gè)非常明顯的特點(diǎn)性能，就是安秒特性。對(duì)熔體來說，其動(dòng)作電流和動(dòng)作時(shí)間特性即熔斷器的安秒特性，也叫反時(shí)延特性，即：過載電流小時(shí)，熔斷時(shí)間長(zhǎng)；過載電流大時(shí)，熔斷對(duì)安秒特性的理解，從焦耳定律上可以看到Q=I2*R*T，串聯(lián)回路里，熔斷器的R值基本不變，成都熔斷器廠家，發(fā)熱量與電流I的平方成正比，與發(fā)熱時(shí)間T成正比，也就是說：當(dāng)電流較大時(shí)，熔體熔斷所需的時(shí)間就較短。而電流較小時(shí)，熔體熔斷所需用的時(shí)間就較長(zhǎng)，甚至如果熱量積累的速度小于熱擴(kuò)散的速度，熔斷器溫度就不會(huì)上升到熔點(diǎn)，成都熔斷器廠家，成都熔斷器廠家，熔斷器甚至不會(huì)熔斷。因此，在一定過載電流范圍內(nèi)，當(dāng)電流恢復(fù)正常時(shí)，熔斷器不會(huì)熔斷，可繼續(xù)使用。

跌落式熔斷器主要功能：熔絲管兩端的動(dòng)觸頭依靠熔絲(熔體)系緊，將上動(dòng)觸頭推入"鴨嘴"凸出部分后，磷銅片等制成的上靜觸頭頂著上動(dòng)觸頭，故而熔絲管牢固地卡在"鴨嘴"里。當(dāng)短路電流通過熔絲熔斷時(shí)，產(chǎn)生電弧，熔絲管內(nèi)襯的鋼紙管在電弧作用下產(chǎn)生大量的氣體因熔絲管上端被封死，氣體向下端噴出，吹滅電弧。由于熔絲熔斷，熔絲管的上下動(dòng)觸頭失去熔絲的系緊力，在熔絲管自身重力和上、下靜觸頭彈簧片的作用下，熔絲管迅速跌落，使電路斷開，切除故障段線路或者故障設(shè)備。

style="text-indent:25px">低壓配電系統(tǒng)中熔斷器是起保護(hù)作用的一種電器，熔斷器多應(yīng)用于電網(wǎng)保護(hù)和用電設(shè)備保護(hù)，當(dāng)電網(wǎng)或用電設(shè)備發(fā)生短路故障或過載時(shí)，可自動(dòng)切斷電路，避免電器設(shè)備損壞，防止***蔓延。熔斷器由絕緣底座（或支持件）、觸頭、熔體等組成，熔體是熔斷器的主要工作部分，熔體相當(dāng)于串聯(lián)在電路中的一段特殊的導(dǎo)線，當(dāng)電路發(fā)生短路或過載時(shí)，電流過大，熔體因過熱而熔化，從而切斷電路。熔體常做成絲狀、柵狀或片狀。熔體材料具有相對(duì)熔點(diǎn)低、特性穩(wěn)定、易于熔斷的特點(diǎn)。一般采用鉛錫合金、鍍銀銅片、鋅、銀等金屬。在熔體熔斷切斷電路的過程中會(huì)產(chǎn)生電弧，為了很好地熄滅電弧，一般均將熔體安裝在熔斷器殼體內(nèi)，采取措施，快速熄滅電弧。</p><p>

style="text-indent:25px">在電氣設(shè)備正常運(yùn)行時(shí)，熔斷器不應(yīng)熔斷；在出現(xiàn)短路時(shí)，應(yīng)立即熔斷；在電流發(fā)生正常變動(dòng)（如電動(dòng)機(jī)起動(dòng)過程）時(shí)，熔斷器不應(yīng)熔斷；在用電設(shè)備持續(xù)過載時(shí)，應(yīng)延時(shí)熔斷。對(duì)熔斷器的選用主要包括類型選擇和熔體額定電流的確定。選擇熔斷器的類型時(shí)，主要依據(jù)負(fù)載的保護(hù)特性和短路電流的大小。比如用于保護(hù)照明和電動(dòng)機(jī)的熔斷器，通常是考慮它們的過載保護(hù)，這時(shí)，希望熔斷器的熔化系數(shù)適當(dāng)小些，所以容量較小的照明線路和電動(dòng)機(jī)宜采用熔體為鉛鋅合金的RC1A系列熔斷器，而大容量的照明線路和電動(dòng)機(jī)，除過載保護(hù)外，還應(yīng)考慮短路時(shí)分?jǐn)喽搪冯娏鞯哪芰?。熔斷器的額定電壓要大于或等于電路的額定電壓。熔斷器的額定電流要依據(jù)負(fù)載情況而選擇。跌落式熔斷器有哪些特點(diǎn)性能？成都熔斷器廠家</p><p style="text-indent:25px">關(guān)于熔斷器你了解多少？成都熔斷器廠家</p><p style="text-indent:25px">高壓跌落式熔斷器三相的操作順序。停電操作時(shí)，應(yīng)先拉中間相，后拉兩邊相。送電時(shí)則先合兩邊相，后合中間相。停電時(shí)先拉中相的原因主要是考慮到中相切斷時(shí)的電流要小于邊相(電路一部分負(fù)荷轉(zhuǎn)由兩相承擔(dān))，因而電弧小，對(duì)兩邊相無危險(xiǎn)。操作第二相(邊相)跌落式熔斷器時(shí)，電流較大，而此時(shí)中相已拉開，另兩個(gè)跌落式熔斷器相距較遠(yuǎn)，可防止電弧拉長(zhǎng)造成相間短路。遇到大風(fēng)時(shí)，要按先拉中間相，再拉背風(fēng)相，之后拉迎風(fēng)相的順序進(jìn)行停電。送電時(shí)則先合迎風(fēng)相，再合背鳳相，末尾合中間相，這樣可以防止風(fēng)吹電弧造成短路。成都熔斷器廠家</p><p
