戶外式熔斷器，用來保護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。
