在21世(shi)紀發展的現(xian)在，汽車(che)行(xing)業也在迅猛(meng)的發展，而汽車(che)電(dian)路中有許(xu)多用電(dian)設(she)備被不(bu)同色(se)彩的電(dian)線連接起來，其間較不(bu)行(xing)忽視的應該是保險絲。保險絲是我們日常習慣叫(jiao)法，在國際標準中叫(jiao)做(zuo)熔斷(duan)器，它(ta)的作用是維護電(dian)路以及用電(dian)設(she)備。

汽(qi)車(che)保險(xian)絲(si)是電(dian)流保險(xian)絲(si)的(de)一(yi)種，當電(dian)路電(dian)流超越(yue)保險(xian)絲(si)額外電(dian)流的(de)2倍時會在幾秒內(nei)熔斷(duan)，起到電(dian)路維(wei)護(hu)的(de)作用(yong)(yong)(yong)。常用(yong)(yong)(yong)于(yu)汽(qi)車(che)電(dian)路過流維(wei)護(hu)，也用(yong)(yong)(yong)于(yu)工業設備的(de)過流維(wei)護(hu)。

汽車(che)保險(xian)(xian)(xian)絲(si)(si)(si)一共分(fen)為插片式(shi)保險(xian)(xian)(xian)絲(si)(si)(si)、叉栓式(shi)保險(xian)(xian)(xian)絲(si)(si)(si)、汽車(che)玻(bo)璃管保險(xian)(xian)(xian)絲(si)(si)(si)這三大類，接下來小編(bian)給大家具體具體講(jiang)講(jiang)這三大保險(xian)(xian)(xian)絲(si)(si)(si)的品種和電流電壓的大致(zhi)范圍(wei)。

插(cha)片式(shi)保(bao)險(xian)(xian)絲(si)(si)可分為：超小號(hao)(hao)插(cha)片保(bao)險(xian)(xian)絲(si)(si)、小號(hao)(hao)汽(qi)車(che)保(bao)險(xian)(xian)絲(si)(si)、中號(hao)(hao)汽(qi)車(che)保(bao)險(xian)(xian)絲(si)(si)、大(da)號(hao)(hao)汽(qi)車(che)保(bao)險(xian)(xian)絲(si)(si)，這些保(bao)險(xian)(xian)絲(si)(si)的額(e)外(wai)電(dian)流有(you)1-40安(an)(an)培(pei)(pei)(A)到(dao)大(da)號(hao)(hao)30-120安(an)(an)培(pei)(pei)(A)，額(e)外(wai)電(dian)壓32伏特(V)；叉栓式(shi)保(bao)險(xian)(xian)絲(si)(si)可分為：小號(hao)(hao)叉栓式(shi)保(bao)險(xian)(xian)絲(si)(si)、大(da)號(hao)(hao)叉栓式(shi)保(bao)險(xian)(xian)絲(si)(si)，額(e)外(wai)電(dian)流有(you)30-150安(an)(an)培(pei)(pei)(A)到(dao)大(da)號(hao)(hao)40-800安(an)(an)培(pei)(pei)(A)，額(e)外(wai)電(dian)壓32/125伏特(V）；汽(qi)車(che)玻(bo)(bo)璃管(guan)保(bao)險(xian)(xian)絲(si)(si)可分為：6.35×30mm玻(bo)(bo)璃管(guan)保(bao)險(xian)(xian)絲(si)(si)、6.35×31.75mm玻(bo)(bo)璃管(guan)保(bao)險(xian)(xian)絲(si)(si)、10×38mm玻(bo)(bo)璃管(guan)保(bao)險(xian)(xian)絲(si)(si)，額(e)外(wai)電(dian)流有(you)0.5-20安(an)(an)培(pei)(pei)(A)到(dao)10×38mm20-80安(an)(an)培(pei)(pei)(A)，額(e)外(wai)電(dian)壓32伏特(V)
