style="text-indent:25px">當(dāng)電流超過規(guī)定值時(shí)，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(shí)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(hù)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(hù)器，是應(yīng)用比較普遍的保護(hù)器件之一。運(yùn)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(shí)，由于其自身發(fā)熱而熔斷，從而分?jǐn)嚯娐返囊环N電器。無錫跌落式熔斷器選擇熔斷器時(shí)，我們應(yīng)該先了解哪些方面？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="無錫跌落式熔斷器,熔斷器" src="http://tyunfile.71360.com/UploadFile/pxbaixin/637188533503652343/6659730.jpg"></div><p> 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；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，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，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。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">戶外式熔斷器工作原理是：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(dòng)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(dòng)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(shí),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(duì)電弧形成強(qiáng)有力的縱向吹弧,使電弧迅速拉長而熄滅.與此同時(shí),由于熔絲熔斷,熔絲的拉力消失,使鎖緊機(jī)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。熔斷器的主要組成構(gòu)造是什么？</p><div

style="text-indent:25px">熔斷器組成的三個(gè)部分主要由熔體、外殼和支座，其中熔體是控制熔斷特性的關(guān)鍵元件。熔體的材料、尺寸和形狀決定了熔斷特性。熔體材料分為低熔點(diǎn)和高熔點(diǎn)兩類。低熔點(diǎn)材料如鉛和鉛合金，其熔點(diǎn)低容易熔斷，因?yàn)槠潆娮杪瘦^大，所以制成熔體的截面尺寸較大，熔斷時(shí)產(chǎn)生的金屬蒸氣較多，只適用于低分?jǐn)嗄芰Φ娜蹟嗥?。高熔點(diǎn)材料如銅、銀，其熔點(diǎn)高，不容易熔斷，但因?yàn)槠潆娮杪瘦^低，可制成比低熔點(diǎn)熔體較小的截面尺寸，熔斷時(shí)產(chǎn)生的金屬蒸氣少，適用于**斷能力的熔斷器。熔體的形狀分為絲狀和帶狀兩類。哪些方面是我們選擇跌落式熔斷器需要注意的呢？無錫跌落式熔斷器</p><p style="text-indent:25px">熔斷器的生產(chǎn)廠家那么多，一定要找正規(guī)的廠家。無錫跌落式熔斷器</p><p> 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(shí)，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。
