style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="福州熔斷器廠家直銷,熔斷器" src="http://tyunfile.71360.com/UploadFile/pxbaixin/637188533639541015/7254425.jpg"></div><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)。當被保護線路發(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備。四川熔斷器廠家直銷選擇跌落式熔斷器的優(yōu)勢有哪些？</p><div

style="text-indent:25px">跌落式熔斷器的安裝和運行維護：跌落式熔斷器瓷件應良好，熔絲管不應有吸潮膨脹、彎曲變形現(xiàn)象。熔絲管上下觸頭的中心線與熔絲管軸線應在同一平面內(nèi)，不得扭歪。跌落式熔斷器應安裝牢固、排列整齊，不得左右轉(zhuǎn)動，10kV跌落式熔斷器相間水平距離不應小于0.5m。為便于操作和熔絲熔斷時自跌，使熔絲管軸線有一定傾斜度，瓷座軸線與地面垂線的夾角一般為20°~30°。分、合閘操作應靈活、可靠，接觸緊密。合閘前調(diào)整上下觸頭應有一定的壓縮行程。在運行中，跌落式熔斷器熔絲熔斷3~4次后，應檢查熔絲管內(nèi)徑是否增大，如果增大2~3mm,則應考慮更換新的熔絲管。在運行中如發(fā)現(xiàn)跌落式熔斷器分、合閘不靈活、則應立即檢修調(diào)整。</p><p> 跌落式熔斷器的注意事項：我們在操作的時候是要戴防護色眼鏡這也是為了避免在操作的時候出現(xiàn)故障卻不知道從而拉還有合的時候會發(fā)生弧光，那樣的話很容易灼傷眼鏡的還需要同時站在一個比較可靠的位置操作的時候，不能夠猶豫需要要果斷并且迅速，但是迅速也不可以用大力，我們用的力是需要適中的。也是為了避免沖擊從而造成不可逆轉(zhuǎn)的對瓷體的損傷。當我們合的時候首先需要要合兩側(cè)也就是兩邊的相然后再合中間相，而拉就需要先拉開中間相了以后然后拉來兩側(cè)這是開關(guān)的時候需要注意的可千萬別弄錯了，而且我們在操作的時候是不允許帶負荷操作的。
