二、產(chǎn)品介紹

   跌落式熔斷器是現今輸配電系統中***的戶(hù)外高壓保護電器,裝置在配電變壓器高壓側或配電線(xiàn)支干線(xiàn)路上,用作變壓器和線(xiàn)路的短路、過(guò)載保護及分、合負荷電流。復合跌落式熔斷器由復合(硅橡膠)絕緣支架和熔絲管二部分組成,靜觸頭安裝在絕緣支架兩端,動(dòng)觸頭安裝在熔絲管兩端,熔絲管由內層的消弧管和外層的酚醛紙管或環(huán)氧玻璃布管組成。拉負荷跌落式熔斷器增強彈性輔助觸頭及滅弧罩,用以分、合負荷電流。

 

三,產(chǎn)品結構

   跌落式熔斷器由絕緣支架和熔絲管兩大部分組成,靜觸頭安裝在絕緣支架的兩端,動(dòng)觸頭安裝在熔絲管的兩端,熔絲管由內層的消弧管和外層環(huán)氧玻璃管組成。拉負荷跌落式熔斷器增加彈性輔助頭及滅弧罩,用以分、合負荷電流。跌落式熔斷器在正常運行時(shí),熔絲管借助熔絲張緊后形成閉合位置。當系統發(fā)生故障時(shí),故障電流使熔絲迅速熔斷,并形成電弧,消弧管受電弧灼熱,分解出大量的氣體,使管內形成很高壓力,并沿管道形成縱吹,電弧被迅速拉長(cháng)而熄滅。熔絲熔斷后,下部動(dòng)觸頭失去張力而下翻,鎖緊機構釋放熔絲管,熔絲管跌落,形成明顯的開(kāi)斷位置。當需要要拉負荷時(shí),用絕緣桿拉開(kāi)動(dòng)觸頭,此時(shí)主動(dòng)、靜助觸頭仍然接觸,繼續用絕緣桿拉動(dòng)觸頭,輔助觸頭也分離,在輔助觸頭之間產(chǎn)生電弧,電弧在滅弧罩狹縫中被拉長(cháng),同時(shí)滅弧罩產(chǎn)生氣體,在電流過(guò)零時(shí),將電弧熄滅。

四、用途

出口型跌落式熔斷器及拉負荷跌落式熔斷器是戶(hù)外高壓保護電器,它裝配在配電變壓器高壓側或配電線(xiàn)支干線(xiàn)路上,作輸電線(xiàn)路、電力變壓器過(guò)載和短路保護及分合額定負荷電流之用。
