保(bao)(bao)(bao)險絲(fuse)也(ye)被稱為電(dian)(dian)(dian)(dian)(dian)流(liu)保(bao)(bao)(bao)險絲，IEC127標準將它(ta)定(ding)義為"熔斷體（fuse-link)"。其主要是起過載(zai)保(bao)(bao)(bao)護作用。電(dian)(dian)(dian)(dian)(dian)路(lu)中(zhong)正確安置保(bao)(bao)(bao)險絲，保(bao)(bao)(bao)險絲就會(hui)在電(dian)(dian)(dian)(dian)(dian)流(liu)異(yi)常升高到(dao)一定(ding)的(de)(de)(de)高度和熱度的(de)(de)(de)時(shi)(shi)候，自身熔斷切(qie)斷電(dian)(dian)(dian)(dian)(dian)流(liu)，保(bao)(bao)(bao)護了(le)電(dian)(dian)(dian)(dian)(dian)路(lu)安全運行當使能(neng)升壓(ya)變換(huan)器，且其輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)超過MAX810的(de)(de)(de)復(fu)位門(men)檻電(dian)(dian)(dian)(dian)(dian)平并經過復(fu)位延(yan)遲后，MAX810的(de)(de)(de)輸出將由高變低，使Q1導通(tong)，連通(tong)負(fu)載(zai)。同時(shi)(shi)，MAX810輸出的(de)(de)(de)低電(dian)(dian)(dian)(dian)(dian)平使端(duan)與NC端(duan)（常閉端(duan)）接通(tong)，使得反饋電(dian)(dian)(dian)(dian)(dian)阻由Q1的(de)(de)(de)源(yuan)極(ji)(ji)(ji)切(qie)換(huan)至Q1的(de)(de)(de)漏(lou)(lou)極(ji)(ji)(ji)，從而允(yun)許從遠離變換(huan)器的(de)(de)(de)負(fu)載(zai)端(duan)對輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)進行調節。上述MAX4544的(de)(de)(de)開關過程也(ye)把MAX810的(de)(de)(de)輸入端(duan)從Q1的(de)(de)(de)源(yuan)極(ji)(ji)(ji)切(qie)換(huan)到(dao)Q1的(de)(de)(de)漏(lou)(lou)極(ji)(ji)(ji)，這樣一來，MAX810可(ke)以(yi)用來監測負(fu)載(zai)是否過載(zai)。高壓(ya)保(bao)(bao)(bao)險絲SBFW如果不能(neng)找到(dao)具(ju)有相同電(dian)(dian)(dian)(dian)(dian)流(liu)負(fu)荷的(de)(de)(de)保(bao)(bao)(bao)險絲，則可(ke)采(cai)用比原保(bao)(bao)(bao)險絲額定(ding)電(dian)(dian)(dian)(dian)(dian)流(liu)低的(de)(de)(de)代替。
