戶外式熔斷器，用來(lái)保護(hù)10kV電力變壓器和電力線路。由固定支持部分、活動(dòng)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(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,形成明顯的斷開距離。使電路斷開，切除故障段線路或者故障設(shè)備。
