保(bao)(bao)(bao)險絲(si)(si)的(de)(de)工作原理(li)是，當(dang)電流(liu)通過(guo)導(dao)體時(shi)，導(dao)體會因為本身具(ju)有的(de)(de)一定(ding)(ding)電阻而發熱(re)(re)(re)。在(zai)確(que)定(ding)(ding)保(bao)(bao)(bao)險絲(si)(si)的(de)(de)材料和(he)(he)形狀后(hou)，還將確(que)定(ding)(ding)其電阻。當(dang)電流(liu)流(liu)過(guo)它(ta)時(shi)，它(ta)會產生熱(re)(re)(re)量(liang)(liang)，其熱(re)(re)(re)量(liang)(liang)也會隨(sui)著時(shi)間的(de)(de)增(zeng)加(jia)而增(zeng)加(jia)。電流(liu)和(he)(he)電阻的(de)(de)大小決定(ding)(ding)了熱(re)(re)(re)量(liang)(liang)產生的(de)(de)速(su)度(du)(du)，保(bao)(bao)(bao)險絲(si)(si)的(de)(de)結構(gou)及其安裝條件決定(ding)(ding)了熱(re)(re)(re)量(liang)(liang)消(xiao)耗的(de)(de)速(su)度(du)(du)。如果(guo)發熱(re)(re)(re)速(su)度(du)(du)小于散熱(re)(re)(re)速(su)度(du)(du)，保(bao)(bao)(bao)險絲(si)(si)不會熔(rong)(rong)斷(duan)(duan)。如果(guo)熱(re)(re)(re)量(liang)(liang)產生的(de)(de)速(su)度(du)(du)與散熱(re)(re)(re)的(de)(de)速(su)度(du)(du)相等(deng)，那么(me)它(ta)的(de)(de)使(shi)用壽命會很長。如果(guo)熱(re)(re)(re)量(liang)(liang)產生的(de)(de)速(su)度(du)(du)大于熱(re)(re)(re)量(liang)(liang)消(xiao)失的(de)(de)速(su)度(du)(du)，產生的(de)(de)熱(re)(re)(re)量(liang)(liang)就會越(yue)來(lai)越(yue)多。熱(re)(re)(re)量(liang)(liang)的(de)(de)增(zeng)加(jia)會導(dao)致溫度(du)(du)升(sheng)(sheng)高。當(dang)溫度(du)(du)升(sheng)(sheng)高到保(bao)(bao)(bao)險絲(si)(si)熔(rong)(rong)點以(yi)上時(shi)，保(bao)(bao)(bao)險絲(si)(si)將熔(rong)(rong)斷(duan)(duan)。0603醫(yi)療保(bao)(bao)(bao)險絲(si)(si)廠(chang)商
