跌落式熔斷器操作時由兩人進行(一人監(jiān)護，一人操作)，但需要戴經(jīng)試驗合格的絕緣手套，穿絕緣靴、戴護目眼鏡，使用電壓等級相匹配的合格絕緣棒操作，在雷電或者大雨的氣候下禁止操作。在拉閘操作時，一般規(guī)定為先拉斷中間相，再拉背風(fēng)的邊相，之后拉斷迎風(fēng)的邊相。這是因為配電變壓器由三相運行改為兩相運行，拉斷中間相時所產(chǎn)生的電弧火花小，不致造成相間短路。其次是拉斷背風(fēng)邊相，因為中間相已被拉開，背風(fēng)邊相與迎風(fēng)邊相的距離增加了一倍，即使有過電壓產(chǎn)生，造成相間短路的可能性也很小。之后拉斷迎風(fēng)邊相時，*有對地的電容電流，產(chǎn)生的電火花則已很輕微。合閘的時候操作順序拉閘時相反，先合迎風(fēng)邊相，再合背風(fēng)的邊相，之后合上中間相。操作熔管是一項頻繁的項目，注意不到便會造成觸頭燒傷引起接觸不良，使觸頭過熱，彈簧退火，促使觸頭接觸更為不良，形成惡性循環(huán)。因此，拉、合熔管時要用力適度，合好后，要仔細(xì)檢查鴨嘴舌頭能緊緊扣住舌頭長度三分之二以上，可用拉閘桿鉤住上鴨嘴向下壓幾下，再輕輕試?yán)?，檢查是否合好。合閘時未能到位或未合牢靠，熔斷器上靜觸頭壓力不足，很容易造成觸頭燒傷或者熔管自行跌落。

充有石英砂的熔斷器，當(dāng)熔體熔斷時，電弧在石英砂中的狹溝里燃燒，根據(jù)狹縫滅弧原理，電弧與周圍填料緊密接觸受到冷卻而熄滅，它的熄弧能力很強，可在電流未到峰值之前就熄滅電弧，具有限流作用。但它會產(chǎn)生過電壓，其過電壓的情況與使用地點的電壓有關(guān)，如果用在低于額定電壓的電網(wǎng)中，過電壓可能達(dá)到3.5-4倍的相電壓，將使電網(wǎng)產(chǎn)生電暈，甚至損壞電網(wǎng)中的設(shè)備。如果用在高于其額定電壓的電網(wǎng)中，則熔斷器產(chǎn)生的過電壓有可能引起電弧重燃，無法再度熄滅，會造成熔斷器外殼燒壞:而用在額定電壓相同的電網(wǎng)中，熔斷時的過電壓*為2-2.5倍的電網(wǎng)相電壓，比設(shè)備的線電壓稍高一些。

style="text-indent:25px">當(dāng)電流超過規(guī)定值時，以本身產(chǎn)生的熱量使熔體熔斷，斷開電路的一種電器叫做熔斷器。熔斷器是根據(jù)電流超過規(guī)定值一段時間后，用其自身產(chǎn)生的熱量使熔體熔化，從而使電路斷開；采用這種原理制成的一種電流保護器。熔斷器多應(yīng)用于高低壓配電系統(tǒng)和控制系統(tǒng)以及用電設(shè)備中，作為短路和過電流的保護器，是應(yīng)用比較普遍的保護器件之一。運用金屬導(dǎo)體作為熔體串聯(lián)于電路中，當(dāng)過載或短路電流通過熔體時，由于其自身發(fā)熱而熔斷，從而分?jǐn)嚯娐返囊环N電器。熔斷器的維護方面應(yīng)該注意什么？</p><div
