近幾年因為劣質電源適配器而引發火災(zai)的(de)案例(li)十分的(de)常(chang)見，大部(bu)分人(ren)會抱怨無良電源(yuan)適配(pei)器廠家(jia)劣勢產(chan)品害人(ren)不淺，實際上(shang)用戶的(de)使用不當(dang)也是產(chan)生火災(zai)最直接的(de)原因。那電源(yuan)適配(pei)器引發火災(zai)怎么回(hui)事?如何防范(fan)?

　　空接電源適配器導致發熱過度

　　電(dian)(dian)(dian)(dian)(dian)源適配(pei)器(qi)一定是(shi)(shi)(shi)一種有源的(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，這(zhe)(zhe)種電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)完成的(de)是(shi)(shi)(shi)對(dui)于(yu)電(dian)(dian)(dian)(dian)(dian)能(neng)的(de)轉化，比如(ru)(ru)說降壓(ya)或(huo)者(zhe)(zhe)是(shi)(shi)(shi)整流。這(zhe)(zhe)部分電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)是(shi)(shi)(shi)會(hui)產(chan)生(sheng)一定的(de)負載的(de)，而在很多(duo)的(de)劣(lie)勢電(dian)(dian)(dian)(dian)(dian)源適配(pei)器(qi)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)之中廠家沒(mei)(mei)(mei)有加(jia)入防(fang)止(zhi)負載持續運作產(chan)生(sheng)的(de)高溫應對(dui)措施。這(zhe)(zhe)樣電(dian)(dian)(dian)(dian)(dian)源適配(pei)器(qi)在實際接入了電(dian)(dian)(dian)(dian)(dian)源但是(shi)(shi)(shi)沒(mei)(mei)(mei)有充電(dian)(dian)(dian)(dian)(dian)的(de)情況之下也是(shi)(shi)(shi)會(hui)發(fa)(fa)熱(re)，在熱(re)到了一定程度就是(shi)(shi)(shi)會(hui)導致內部的(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)損(sun)壞(huai)，并且這(zhe)(zhe)種損(sun)壞(huai)很多(duo)也是(shi)(shi)(shi)伴隨著短路(lu)(lu)的(de)現(xian)象發(fa)(fa)生(sheng)，這(zhe)(zhe)種短路(lu)(lu)的(de)現(xian)象發(fa)(fa)生(sheng)對(dui)于(yu)自己房間之內的(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)存在很大的(de)危害(hai)。如(ru)(ru)果沒(mei)(mei)(mei)有安(an)裝保險絲或(huo)者(zhe)(zhe)是(shi)(shi)(shi)空氣閘的(de)話發(fa)(fa)生(sheng)火災的(de)可能(neng)性十(shi)分大。

　　過量充電導致電池破裂爆炸

　　過(guo)(guo)量充電(dian)(dian)也是(shi)會(hui)導致(zhi)電(dian)(dian)源適配器產生巨大的(de)熱(re)量其帶(dai)來的(de)后果(guo)在上文(wen)之(zhi)中(zhong)我們已經(jing)是(shi)解釋(shi)過(guo)(guo)了，但是(shi)同(tong)時應當知道的(de)就是(shi)這(zhe)種過(guo)(guo)量的(de)充電(dian)(dian)對于電(dian)(dian)池(chi)也是(shi)一種傷害。如果(guo)是(shi)充電(dian)(dian)時間過(guo)(guo)長的(de)話電(dian)(dian)池(chi)有可能會(hui)爆炸，現在的(de)電(dian)(dian)池(chi)多是(shi)采用惰性鋰來維持(chi)供(gong)電(dian)(dian)，一旦燃燒這(zhe)種鋰元(yuan)素會(hui)被激(ji)活(huo)并且是(shi)在空氣之(zhi)中(zhong)急(ji)速的(de)氧(yang)化并且是(shi)產生熱(re)量。這(zhe)就是(shi)會(hui)導致(zhi)火災(zai)的(de)發(fa)生。
