Okwamanje Okujwayelekile: Okokuqala kufanele sazi usayizi wamanje ojwayelekile ogeleza ku-fuse kusekethe esetshenzisiwe.
Imvamisa kufanele sibeke ukwehliswa ngaphambi kwesikhathi, bese sikhetha ngokuya ngomgomo olandelayo: okungukuthi, i-current evamile kufanele ibe ngaphansi komkhiqizo wamanje okaliwe kanye ne-coefficient yokwehlisa.
I-2.Fuse yamanje: Ngokuya ngemininingwane ye-UL, i-fuse kufanele ihlanganiswe ngokushesha kumanje olinganisiwe kaningi. Ezimweni eziningi, noma kunjalo, ukuze kuqinisekiswe i-fuse ethembekile, sincoma ukuthi i-fuse current kufanele ibe nkulu kunangezikhathi ezi-2.5 zamanje ezilinganisiwe.
Ngaphezu kwalokho, isikhathi se-fuse sibalulekile, kepha futhi kufanele sikhombe kumdwebo wesici se-fuse esinikezwe ngumenzi ukwenza isahlulelo.
I-3.Open Circuit Voltage: i-voltage yesekethe evulekile kufanele ikhethwe ngokubanzi ukuthi ibe ngaphansi kwamandla kagesi alinganisiwe.
Isibonelo, lapho i-fuse ene-voltage elinganisiwe ye-dc24v isetshenziswa kumjikelezo we-ac100v, kungenzeka ukubasa noma ukuphula i-fuse.
I-4.Short-circuit yamanje: Inani eliphakeme lamanje esigelezayo lapho isifunda sifushane-circuited libizwa ngokuthi yi-short-circuit current. Kuma-fuse ahlukahlukene, inani lekhefu elilinganisiwe liyacaciswa, futhi kufanele siqaphele ukuthi singenzi i-short-circuit current idlule amandla wesifunda akaliwe lapho kukhethwa i-fuse.
Uma kukhethwa i-fuse enamandla amancane wesifunda ephukile, ingahle iphule i-fuse noma ibange umlilo.
I-5.Impact yamanje: I-waveform (i-pulse wave waveform) yokubheka umthelela wamanje isetshenziselwa ukubala amandla ayo kusetshenziswa inani le-I2T (inani elihlanganisiwe le-Joule). Umthelela wamanje uhlukile ngosayizi nobuningi, futhi umphumela ku-fuse uhlukile. Isilinganiso senani le-i2t lomthelela wamanje kunani le-fuse i2t le-pulse eyodwa linquma inani lezikhathi lapho i-fuse imelana nomthelela wamanje.
