style="text-indent:25px">熔斷器的動(dòng)作是靠熔體的熔斷來(lái)實(shí)現(xiàn)的，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(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。嘉興跌落式熔斷器供應(yīng)商熔斷器的分類那么多，該如何選擇？</p><div

跌落式熔斷器安裝時(shí)應(yīng)將熔體拉緊(使熔體大約受到24.5N左右的拉力)，否則容易引起觸頭發(fā)熱。熔斷器安裝在橫擔(dān)(構(gòu)架)上應(yīng)牢固可靠，不能有任何的晃動(dòng)或搖晃現(xiàn)象。熔管應(yīng)有向下25°±2°的傾角，以利熔體熔斷時(shí)熔管能依靠自身重量迅速跌落。熔斷器應(yīng)安裝在離地面垂直距離不小于4m的橫擔(dān)(構(gòu)架)上，若安裝在配電變壓器上方，應(yīng)與配變的外輪廓邊界保持0.5m以上的水平距離，以防萬(wàn)一熔管掉落引發(fā)其他***。熔管的長(zhǎng)度應(yīng)調(diào)整適中，要求合閘后鴨嘴舌頭能扣住觸頭長(zhǎng)度的三分之二以上，以免在運(yùn)行中發(fā)生自行跌落的誤動(dòng)作，熔管亦不可頂死鴨嘴，以防止熔體熔斷后熔管不能及時(shí)跌落。所使用的熔體需要是正規(guī)廠家的標(biāo)準(zhǔn)產(chǎn)品，并具有一定的機(jī)械強(qiáng)度，通常要求熔體至少能承受147N以上的拉力。10kV跌落式熔斷器安裝在戶外，要求相間距離大于70cm </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(zhǎng)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(kāi)距離。使電路斷開(kāi)，切除故障段線路或者故障設(shè)備。哪些方面是我們選擇跌落式熔斷器需要注意的呢？</p><div
