簡短描述:

熔(rong)(rong)(rong)斷(duan)器(qi)是指當(dang)電(dian)(dian)(dian)(dian)(dian)流超(chao)過(guo)規定(ding)值時，以本身產(chan)生(sheng)(sheng)的(de)(de)(de)熱(re)量使熔(rong)(rong)(rong)體(ti)熔(rong)(rong)(rong)斷(duan)，斷(duan)開電(dian)(dian)(dian)(dian)(dian)路的(de)(de)(de)一種電(dian)(dian)(dian)(dian)(dian)器(qi)。熔(rong)(rong)(rong)斷(duan)器(qi)是根據電(dian)(dian)(dian)(dian)(dian)流超(chao)過(guo)規定(ding)值一段時間后，以其自身產(chan)生(sheng)(sheng)的(de)(de)(de)熱(re)量使熔(rong)(rong)(rong)體(ti)熔(rong)(rong)(rong)化(hua)，從而使電(dian)(dian)(dian)(dian)(dian)路斷(duan)開；運用(yong)這種原理(li)(li)制(zhi)成(cheng)的(de)(de)(de)一種電(dian)(dian)(dian)(dian)(dian)流保護(hu)器(qi)。熔(rong)(rong)(rong)斷(duan)器(qi)廣泛(fan)應用(yong)于高(gao)低壓配電(dian)(dian)(dian)(dian)(dian)系(xi)統和控制(zhi)系(xi)統以及(ji)用(yong)電(dian)(dian)(dian)(dian)(dian)設備(bei)中，作(zuo)為(wei)短路和過(guo)電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)保護(hu)器(qi)，是應用(yong)最(zui)普遍的(de)(de)(de)保護(hu)器(qi)件(jian)之(zhi)一。銘(ming)玨(jue)金(jin)屬(shu)開發的(de)(de)(de)熔(rong)(rong)(rong)斷(duan)器(qi)專用(yong)銅(tong)箔(bo)，是一款作(zuo)為(wei)熔(rong)(rong)(rong)斷(duan)器(qi)熔(rong)(rong)(rong)體(ti)的(de)(de)(de)理(li)(li)想材料(liao)(liao)。經過(guo)脫(tuo)脂處(chu)理(li)(li)和表(biao)面(mian)常溫抗氧(yang)化(hua)處(chu)理(li)(li)后的(de)(de)(de)銅(tong)箔(bo)，可以有(you)(you)效的(de)(de)(de)延(yan)長銅(tong)箔(bo)表(biao)面(mian)氧(yang)化(hua)周(zhou)期。為(wei)了能更(geng)好(hao)的(de)(de)(de)配合客戶的(de)(de)(de)需求(qiu)，銘(ming)玨(jue)金(jin)屬(shu)還可以對(dui)材料(liao)(liao)進行電(dian)(dian)(dian)(dian)(dian)鍍處(chu)理(li)(li)，從而讓銅(tong)箔(bo)具有(you)(you)更(geng)好(hao)的(de)(de)(de)耐腐蝕(shi)性(xing)能。
