style="text-indent:25px">跌落式熔斷器其工作原理是：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(guò)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(kāi)，切除故障段線路或者故障設(shè)備。</p><p style="text-indent:25px">對(duì)熔體來(lái)說(shuō)，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(guò)載電流小時(shí)，熔斷時(shí)間長(zhǎng)；過(guò)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，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(shuō)：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)，熔斷器甚至不會(huì)熔斷。因此，在一定過(guò)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。熔斷器的型號(hào)該怎么選擇？</p><div
