一、概述

    跌落(luo)式(shi)(shi)熔斷(duan)器(qi)及(ji)拉負(fu)荷跌落(luo)式(shi)(shi)熔斷(duan)器(qi)是(shi)戶外(wai)高(gao)壓保護(hu)電(dian)器(qi)。它裝置在配(pei)電(dian)變(bian)壓器(qi)高(gao)壓側或配(pei)電(dian)線(xian)支干線(xian)路(lu)上、用(yong)作(zuo)變(bian)壓器(qi)和線(xian)路(lu)的(de)短(duan)路(lu)、過(guo)載保護(hu)及(ji)分(fen)、合負(fu)荷電(dian)流(liu)(liu)。跌落(luo)式(shi)(shi)熔斷(duan)器(qi)由(you)絕(jue)緣支架和熔絲(si)管(guan)二部分(fen)組(zu)成(cheng)，靜(jing)觸頭(tou)安(an)裝在絕(jue)緣支架兩端，動觸頭(tou)安(an)裝在熔絲(si)管(guan)兩端，熔絲(si)管(guan)由(you)內(nei)層的(de)消弧(hu)管(guan)和外(wai)層的(de)酚醛(quan)紙管(guan)或環氧玻璃(li)布管(guan)組(zu)成(cheng)。拉負(fu)荷跌落(luo)式(shi)(shi)熔斷(duan)器(qi)增強(qiang)彈性輔助觸頭(tou)及(ji)滅弧(hu)罩，用(yong)以分(fen)，合負(fu)荷電(dian)流(liu)(liu)。

    跌(die)落式熔(rong)(rong)斷(duan)器在正常運行時(shi)(shi)，熔(rong)(rong)絲(si)管借助熔(rong)(rong)絲(si)張緊(jin)后形(xing)成(cheng)(cheng)(cheng)閉合位置。當系(xi)統發(fa)生(sheng)(sheng)故障(zhang)時(shi)(shi)，故障(zhang)電(dian)(dian)(dian)流時(shi)(shi)熔(rong)(rong)絲(si)迅速熔(rong)(rong)斷(duan)，并形(xing)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)弧(hu)(hu)，消弧(hu)(hu)管受電(dian)(dian)(dian)弧(hu)(hu)灼熱，分解出大(da)量的氣體，使館內形(xing)成(cheng)(cheng)(cheng)很(hen)高壓(ya)力，并沿(yan)管道形(xing)成(cheng)(cheng)(cheng)縱吹，電(dian)(dian)(dian)弧(hu)(hu)被迅速拉長(chang)而熄(xi)滅。熔(rong)(rong)絲(si)熔(rong)(rong)斷(duan)后，下部動(dong)(dong)觸(chu)(chu)頭(tou)(tou)(tou)(tou)失去張力二(er)下翻，鎖緊(jin)機(ji)械，釋放熔(rong)(rong)絲(si)管，熔(rong)(rong)絲(si)管跌(die)落，形(xing)成(cheng)(cheng)(cheng)明顯的開斷(duan)位置。當需要拉負荷時(shi)(shi)，用絕(jue)緣(yuan)桿(gan)拉開動(dong)(dong)觸(chu)(chu)頭(tou)(tou)(tou)(tou)，此時(shi)(shi)主(zhu)動(dong)(dong)、靜動(dong)(dong)觸(chu)(chu)頭(tou)(tou)(tou)(tou)仍然接觸(chu)(chu)，繼(ji)續用絕(jue)緣(yuan)桿(gan)拉動(dong)(dong)觸(chu)(chu)頭(tou)(tou)(tou)(tou)，輔助觸(chu)(chu)頭(tou)(tou)(tou)(tou)也分離，在輔助觸(chu)(chu)頭(tou)(tou)(tou)(tou)之間產生(sheng)(sheng)電(dian)(dian)(dian)弧(hu)(hu)，電(dian)(dian)(dian)弧(hu)(hu)在滅罩狹縫中被拉長(chang)，同時(shi)(shi)滅弧(hu)(hu)罩產生(sheng)(sheng)氣體，在電(dian)(dian)(dian)流過(guo)零時(shi)(shi)，將電(dian)(dian)(dian)弧(hu)(hu)熄(xi)滅。

二、用途

    戶外高(gao)壓(ya)(ya)熔斷(duan)器(qi)適用于35kv及以下(xia)電(dian)壓(ya)(ya)頻率50Hz電(dian)力(li)系統(tong)中(zhong)，作輸電(dian)線路、電(dian)力(li)變(bian)壓(ya)(ya)器(qi)過載(zai)和短路保護，分合額定負(fu)荷電(dian)流只(zhi)用，機械壽命≥2000次。

三、使用條件

1.適(shi)用于環境溫度上(shang)限40℃，下限-30℃之內。

2.海拔不超過1000m，風速(su)不大于35m/s

3.熔(rong)斷(duan)器不適用于(yu)下述場(chang)所(suo)

3.2有(you)劇烈震動或沖(chong)擊的場所(suo)。

3.3有異電化(hua)學氣體作用及嚴重空氣污穢(hui)，煙(yan)霧地區。

四、結構簡介

    熔(rong)斷器是由(you)基座和消弧裝置(zhi)兩大部(bu)分組成，滅(mie)(mie)弧管(guan)下(xia)端裝有可能轉動的彈簧支架，始終使熔(rong)絲處(chu)于緊張狀態，以保證滅(mie)(mie)弧管(guan)在合閘位置(zhi)的自(zi)鎖，線路與變壓器過(guo)載或短路中(zhong)，熔(rong)絲熔(rong)斷，熔(rong)絲迅(xun)速從(cong)滅(mie)(mie)弧管(guan)中(zhong)抽(chou)出，滅(mie)(mie)弧管(guan)設計為逐(zhu)級排氣式解決在同一熔(rong)斷器上開(kai)斷大小電流的矛盾。
