Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev siv fuses los tiv thaiv circuits?
Lub ntsiab zoo thiab cov yam ntxwv ntawm fuses:
① Kev xaiv zoo. Ntev npaum li qhov ntsuas tam sim no ntawm fuse txuas ntawm qib siab thiab qis fuses ua tau raws li qhov yuav tsum tau ua ntawm lub teb chaws tus qauv thiab IEC tus qauv uas qhov kev xaiv overcurrent piv yog 1.6: 1, uas yog, qhov ntsuas tam sim no ntawm qib siab fuse txuas. tsis tsawg dua 1.6 npaug ntawm tus nqi ntawm qib qis, nws suav tias yog qib siab thiab qis dua. Xaiv txiav tawm qhov txhaum tam sim no; ② Cov yam ntxwv zoo tam sim no txwv, muaj peev xwm tawg siab; ③ me me; ④ Tus nqi pheej yig dua.
Lub ntsiab qhov tsis zoo thiab qhov tsis muaj zog ntawm fuses:
① Lub fuse yuav tsum tau hloov tom qab lub tshuab ua txhaum; ② Kev tiv thaiv muaj nuj nqi yog ib leeg, thiab tsuas yog ib feem ntawm overcurrent inverse time characteristic, uas yog siv los tiv thaiv overload, luv Circuit Court thiab av txhaum; ③ Thaum ib-theem fusing tshwm sim, nws yuav ua rau muaj kev cuam tshuam tsis zoo ntawm ob-theem kev ua haujlwm rau peb-theem motors. Tau kawg, nws tuaj yeem them nyiaj los ntawm lub fuse nrog lub tswb nrov. Ib-theem fusing tuaj yeem txiav peb theem; ④ Kev tswj chaw taws teeb tsis tuaj yeem paub, nws yuav tsum tau ua ke nrog hluav taws xob riam hloov thiab hloov mus ua tau.
