，轎(jiao)車(che)保(bao)險(xian)絲(si)座(zuo)的(de)保(bao)險(xian)絲(si)應(ying)在(zai)固(gu)定(ding)時(shi)間(jian)內(nei)阻(zu)攔(lan)過(guo)載(zai)電(dian)流(liu)。轎(jiao)車(che)保(bao)險(xian)絲(si)座(zuo)能(neng)夠(gou)在(zai)必(bi)定(ding)程(cheng)度(du)上(shang)需(xu)要(yao)保(bao)持(chi)控(kong)製(zhi)電(dian)路(lu)中(zhong)其(qi)他(ta)電(dian)子(zi)設(she)備(bei)元(yuan)件(jian)的(de)安(an)全(quan)性(xing)。當(dang)電路結構發生各種短路並顯示大電流時，保險絲能夠有用安全地堵截電路

，然後到達避免因過電流而損壞電路。  

轎車保險絲架中的熔斷器能夠在等於或小於其額外電壓的電壓下運用，但一般不能用於電路電壓大於熔斷器額外電壓的電路。

一般保險絲座由三個重要部分組成：  

一(yi)是(shi)熔(rong)化(hua)部(bu)分(fen)，它(ta)是(shi)熔(rong)斷(duan)器(qi)的(de)中(zhong)心(xin)，在(zai)熔(rong)斷(duan)時(shi)具(ju)有(you)堵(du)塞(sai)電(dian)流(liu)的(de)效(xiao)果(guo)。相(xiang)同(tong)類(lei)型(xing)和(he)相(xiang)同(tong)規(gui)範(fan)熔(rong)斷(duan)器(qi)的(de)熔(rong)體(ti)應(ying)由(you)具(ju)有(you)相(xiang)同(tong)幾(ji)許(xu)尺(chi)度(du)的(de)相(xiang)同(tong)材(cai)料(liao)製(zhi)成(cheng)，其(qi)電(dian)阻(zu)值(zhi)盡(jin)可(ke)能(neng)小(xiao)，且(qie)一(yi)致(zhi)
，重(zhong)要(yao)的(de)是(shi)具(ju)有(you)相(xiang)同(tong)的(de)熔(rong)斷(duan)器(qi)特(te)性(xing)。  

二(er)，一(yi)般(ban)存(cun)在(zai)兩(liang)個(ge)電(dian)極(ji)元(yuan)件(jian)，它(ta)們(men)連(lian)接(jie)在(zai)熔(rong)體(ti)和(he)電(dian)路(lu)之(zhi)間(jian)的(de)重(zhong)要(yao)組(zu)件(jian)。他(ta)們(men)必(bi)須(xu)有(you)良(liang)好(hao)的(de)導(dao)電(dian)性(xing)，並(bing)且(qie)不(bu)應(ying)該(gai)發(fa)生(sheng)觸(chu)摸(mo)設(she)備(bei)阻(zu)力(li)顯(xian)著(zhu)性(xing)。
