高壓跌落式熔斷器的內(nèi)熔絲一般用銅和銀等材料制成，因為銅和銀的電阻率很小，導(dǎo)電性能強，所以導(dǎo)線可以做細(xì)些，這樣有利于滅弧,但它們的熔點很高，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℃)的熔點時，小球珠先熔化，使熔絲中斷，中斷點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。

戶外式熔斷器，用來保護(hù)10kV電力變壓器和電力線路。由固定支持部分、活動熔管及熔絲組成，固定支持部分為瓷或合成絕緣體。其工作原理是：將熔絲穿入熔管內(nèi),兩端擰緊,并使熔絲位于熔管中間偏上方,上動觸頭由于熔絲拉緊的張力而垂直于熔絲管向上翹起,用絕緣拉桿將上動觸頭推入上靜觸頭內(nèi),成閉合狀態(tài)(合閘狀態(tài))并保持這一狀態(tài)。當(dāng)被保護(hù)線路發(fā)生故障,故障電流使熔絲熔斷時,形成電弧,消弧管在電弧高溫作用下分解出大量氣體,使管內(nèi)壓力急劇增大,氣體向外高速噴出,對電弧形成強有力的縱向吹弧,使電弧迅速拉長而熄滅.與此同時,由于熔絲熔斷,熔絲的拉力消失,使鎖緊機構(gòu)釋放,熔絲管在上靜觸頭的彈力及其自重的作用下,繞下軸翻轉(zhuǎn)跌落,形成明顯的斷開距離。使電路斷開，切除故障段線路或者故障設(shè)備。

"絕緣子", "電力元器件", "避雷器", "熔斷器" ]設(shè)施發(fā)展方面已形成了復(fù)合國情的技術(shù)基礎(chǔ)和產(chǎn)業(yè)基礎(chǔ)，但是市場對科學(xué)合理布局、提高服務(wù)水平也提出更高要求，體驗差、投資效益不佳的矛盾依然突出，相關(guān)設(shè)施的總體發(fā)展水平還有待提高。隨著家庭，辦公室，汽車，酒店和娛樂場所的[ "絕緣子", "電力元器件", "避雷器", "熔斷器" ]的數(shù)量的增加和普及，使用者無需再顧慮電池，并且使用者數(shù)量也將持續(xù)不斷地增長。反過來，這也延長了電池的使用壽命。此外，[ "絕緣子", "電力元器件", "避雷器", "熔斷器"
