直流熔斷器：

【直流熔(rong)(rong)斷(duan)器主要由熔(rong)(rong)體(ti)和熔(rong)(rong)管以及外(wai)加填料等部分組成。使(shi)用時(shi)，將熔(rong)(rong)斷(duan)器串(chuan)聯于(yu)被保護電(dian)(dian)路中，當被保護電(dian)(dian)路的(de)電(dian)(dian)流超過規定值，并經過一(yi)定時(shi)間后，由熔(rong)(rong)體(ti)自身產(chan)生(sheng)的(de)熱量熔(rong)(rong)斷(duan)熔(rong)(rong)體(ti)，使(shi)電(dian)(dian)路斷(duan)開，從(cong)而起到保護的(de)作用】。以(yi)金屬導體(ti)作為熔(rong)(rong)(rong)體(ti)而分斷(duan)電(dian)路(lu)(lu)的電(dian)器(qi)，串聯于(yu)電(dian)路(lu)(lu)中，當(dang)過載(zai)(zai)或短路(lu)(lu)電(dian)流(liu)通過熔(rong)(rong)(rong)體(ti)時(shi)(shi)，熔(rong)(rong)(rong)體(ti)自身將發熱而熔(rong)(rong)(rong)斷(duan)，從而對電(dian)力系統、各種(zhong)電(dian)工設備以(yi)及家用(yong)電(dian)器(qi)都起到了一定的保護作用(yong)。具有反時(shi)(shi)延特性，當(dang)過載(zai)(zai)電(dian)流(liu)小時(shi)(shi)，熔(rong)(rong)(rong)斷(duan)時(shi)(shi)間長(chang)；過載(zai)(zai)電(dian)流(liu)大時(shi)(shi)，熔(rong)(rong)(rong)斷(duan)時(shi)(shi)間短。因此，在一定過載(zai)(zai)電(dian)流(liu)范(fan)圍內(nei)至電(dian)流(liu)恢(hui)復正常，熔(rong)(rong)(rong)斷(duan)器(qi)不會熔(rong)(rong)(rong)斷(duan)，可以(yi)繼續使用(yong)，直流(liu)熔(rong)(rong)(rong)斷(duan)器(qi)是一種(zhong)過電(dian)流(liu)保護器(qi)。 

直流熔斷器構(gou)成：

熔(rong)斷器(qi)主要(yao)由熔(rong)體(ti)、外殼和(he)支座3部分(fen)組成(cheng)，其中熔(rong)體(ti)是(shi)控(kong)制(zhi)熔(rong)斷特性的關鍵(jian)元件(jian)。熔(rong)體(ti)的材料、尺寸和(he)形狀(zhuang)決定了(le)熔(rong)斷特性。

直流(liu)熔斷器特性：

【熔(rong)(rong)(rong)(rong)斷器(qi)具有反時延特性，即過(guo)載電(dian)流(liu)小時，熔(rong)(rong)(rong)(rong)斷時間長；過(guo)載電(dian)流(liu)大時，熔(rong)(rong)(rong)(rong)斷時間短。所以，在一定過(guo)載電(dian)流(liu)范圍內，當電(dian)流(liu)恢復正常時，熔(rong)(rong)(rong)(rong)斷器(qi)不會(hui)熔(rong)(rong)(rong)(rong)斷，可(ke)繼續(xu)使(shi)用(yong)。熔斷器有(you)各(ge)種不同的熔斷特(te)性(xing)曲(qu)線(xian)，可以適用(yong)于不同類型保護(hu)對象的需要】。
