工作原理：1，当电流(liu)(liu)流(liu)(liu)过导体(ti)时(shi)(shi)(shi)，因导体(ti)存在一定(ding)的(de)(de)(de)电阻(zu)(zu)，所以(yi)导体(ti)将(jiang)会(hui)(hui)发(fa)热(re)(re)(re)。且发(fa)热(re)(re)(re)量(liang)(liang)遵循着这个公式：Q=0.24I2RT；其中Q是(shi)发(fa)热(re)(re)(re)量(liang)(liang)，0.24是(shi)一个常(chang)数(shu)，I是(shi)流(liu)(liu)过导体(ti)的(de)(de)(de)电流(liu)(liu)，R是(shi)导体(ti)的(de)(de)(de)电阻(zu)(zu)，T是(shi)电流(liu)(liu)流(liu)(liu)过导体(ti)的(de)(de)(de)时(shi)(shi)(shi)间(jian)；依此(ci)公式我们不(bu)难(nan)看出熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)的(de)(de)(de)简单的(de)(de)(de)工作原理了(le)(le)。一种熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)当制作熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)的(de)(de)(de)材料及其形状确(que)定(ding)了(le)(le)，其电阻(zu)(zu)R就相对确(que)定(ding)了(le)(le)（若不(bu)考虑它(ta)(ta)的(de)(de)(de)电阻(zu)(zu)温(wen)(wen)度系数(shu)）。2，当电流(liu)(liu)流(liu)(liu)过它(ta)(ta)时(shi)(shi)(shi)，它(ta)(ta)就会(hui)(hui)发(fa)热(re)(re)(re)，随着时(shi)(shi)(shi)间(jian)的(de)(de)(de)增(zeng)加(jia)其发(fa)热(re)(re)(re)量(liang)(liang)也在增(zeng)加(jia)。电流(liu)(liu)与(yu)电阻(zu)(zu)的(de)(de)(de)大小确(que)定(ding)了(le)(le)产(chan)(chan)生(sheng)(sheng)(sheng)(sheng)热(re)(re)(re)量(liang)(liang)的(de)(de)(de)速(su)度，熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)的(de)(de)(de)构造(zao)与(yu)其安(an)装的(de)(de)(de)状况确(que)定(ding)了(le)(le)热(re)(re)(re)量(liang)(liang)耗(hao)散(san)的(de)(de)(de)速(su)度，若产(chan)(chan)生(sheng)(sheng)(sheng)(sheng)热(re)(re)(re)量(liang)(liang)的(de)(de)(de)速(su)度小于(yu)热(re)(re)(re)量(liang)(liang)耗(hao)散(san)的(de)(de)(de)速(su)度时(shi)(shi)(shi)，熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)是(shi)不(bu)会(hui)(hui)熔(rong)(rong)断(duan)(duan)(duan)的(de)(de)(de)。若产(chan)(chan)生(sheng)(sheng)(sheng)(sheng)热(re)(re)(re)量(liang)(liang)的(de)(de)(de)速(su)度等于(yu)热(re)(re)(re)量(liang)(liang)耗(hao)散(san)的(de)(de)(de)速(su)度时(shi)(shi)(shi)，在相当长的(de)(de)(de)时(shi)(shi)(shi)间(jian)内它(ta)(ta)也不(bu)会(hui)(hui)熔(rong)(rong)断(duan)(duan)(duan)。3，若产(chan)(chan)生(sheng)(sheng)(sheng)(sheng)热(re)(re)(re)量(liang)(liang)的(de)(de)(de)速(su)度大于(yu)热(re)(re)(re)量(liang)(liang)耗(hao)散(san)的(de)(de)(de)速(su)度时(shi)(shi)(shi)，那么产(chan)(chan)生(sheng)(sheng)(sheng)(sheng)的(de)(de)(de)热(re)(re)(re)量(liang)(liang)就会(hui)(hui)越来越多。又因为它(ta)(ta)有(you)一定(ding)比(bi)热(re)(re)(re)及质(zhi)量(liang)(liang)，其热(re)(re)(re)量(liang)(liang)的(de)(de)(de)增(zeng)加(jia)就表(biao)现在温(wen)(wen)度的(de)(de)(de)升高上，当温(wen)(wen)度升高到(dao)熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)的(de)(de)(de)熔(rong)(rong)点(dian)以(yi)上时(shi)(shi)(shi)熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)就发(fa)生(sheng)(sheng)(sheng)(sheng)了(le)(le)熔(rong)(rong)断(duan)(duan)(duan)。这就是(shi)熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)的(de)(de)(de)工作原理。熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)的(de)(de)(de)安(an)装应符(fu)合相关(guan)的(de)(de)(de)安(an)全规范和标准，确(que)保(bao)正常(chang)运行和提(ti)供(gong)有(you)效的(de)(de)(de)保(bao)护。汕尾直流(liu)(liu)熔(rong)(rong)断(duan)(duan)(duan)器(qi)(qi)企业
