高壓跌落式熔斷器的內(nèi)熔絲一般用銅和銀等材料制成，因?yàn)殂~和銀的電阻率很小，導(dǎo)電性能強(qiáng)，所以導(dǎo)線可以做細(xì)些，這樣有利于滅弧,但它們的熔點(diǎn)很高，可使熔斷器的熔管過熱，易于損壞。所以用銀和銅質(zhì)做的熔絲，均采用人為的方法使熔絲的熔點(diǎn)降低，即在熔絲上焊上小錫珠或鉛珠。當(dāng)熔絲加熱到錫(232℃)或鉛(327℃)的熔點(diǎn)時，小球珠先熔化，使熔絲中斷，中斷點(diǎn)所形成的電弧使熔絲朝兩邊熔化，從而保護(hù)線路或電氣設(shè)備不受過大電流的發(fā)熱而損壞。

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，可自動切斷電路，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，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。熔體材料具有相對熔點(diǎn)低、特性穩(wěn)定、易于熔斷的特點(diǎn)。</p><p> 跌落式熔斷器操作時由兩人進(jìn)行(一人監(jiān)護(hù)，一人操作)，但需要戴經(jīng)試驗(yàn)合格的絕緣手套，穿絕緣靴、戴護(hù)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?yàn)榕潆娮儔浩饔扇噙\(yùn)行改為兩相運(yùn)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?yàn)橹虚g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(xiàng)頻繁的項(xiàng)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。

熔斷器有個非常明顯的特點(diǎn)性能，就是安秒特性。對熔體來說，其動作電流和動作時間特性即熔斷器的安秒特性，也叫反時延特性，即：過載電流小時，熔斷時間長；過載電流大時，熔斷對安秒特性的理解，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)熱時間T成正比，也就是說：當(dāng)電流較大時，熔體熔斷所需的時間就較短。而電流較小時，熔體熔斷所需用的時間就較長，甚至如果熱量積累的速度小于熱擴(kuò)散的速度，熔斷器溫度就不會上升到熔點(diǎn)，熔斷器甚至不會熔斷。因此，在一定過載電流范圍內(nèi)，當(dāng)電流恢復(fù)正常時，熔斷器不會熔斷，可繼續(xù)使用。
