Isimo Esijwayelekile Sokusebenza kanye Nendawo Yokufaka

1. Izinga lokushisa eliphakathi: -5℃ ~ 40℃, izinga lokushisa eliphakathi kwamahora angama-24 alidluli +35℃

2. Ukuphakama: akudluli ku-2000m

3. Umkhathi: umswakama wawo ohlobene awudluli ku-50% uma useku-40℃, ungaba nomswakama ophezulu uma usekushiseni okuphansi, isibonelo, umswakama ohlobene ungafinyelela ku-90% uma useku-20℃. Kufanele kucatshangelwe

ukujiya kwenzeke emikhiqizweni ngenxaukuhlukahluka kwezinga lokushisa

4. I-Voltage: i-voltage ephezulu yesistimu akufanele idlule u-110% we-voltage ekalwe yi-fuse

5. Isigaba sokufakwa: Ⅲ

6. Ibanga lokungcoliswa: okungenani ama-3

7.Isikhundla sokufakwa: singafakwa ngokuqondile ezindaweni ezingenakho ukushukuma okusobala kanye nokudlidliza okushukumayo

Ukwephula Ububanzi kanye Nesigaba Sokusetshenziswa

Umthamo wokuphuka kwefusi: "g", isigaba sokusetshenziswa: "G", okuwukusetshenziswa okuvamile kanye nohlu oluphelele lwe-fuse yomthamo wokuphuka.

Izici Zesakhiwo

● Le fuse yakhiwe ngesixhumanisi sefuse kanye nesiphathi sefuse.

● Isixhumanisi se-fuse sakhiwe ngethubhu yokuhlanganisa, isixhumanisi se-fuse kanye nokugcwalisa. Isixhumanisi se-fuse esenziwe ngomucu wethusi omsulwa noma ucingo sifakwe eshubhu yokuhlanganisa enamandla aphezulu, kanti ithubhu yokuhlanganisa igcwele isihlabathi se-quartz esimsulwa esiphezulu njenge-arc-extinguishing medium. Isixhumanisi se-fuse sixhunywe ngokuqinile nesivalo sokugcina ngokushisela.

●I-fuse ivalwe ngokuphelele uma isebenza. Isibambi se-fuse singaba nesibani sokukhombisa, isibani sokukhombisa sizokhanyiswa uma isixhumanisi se-fuse sihlanganiswa. Isibambi se-fuse sisebenzisa ukufakwa kwesitimela se-DIN esijwayelekile se-TH35, ama-terminal ayo amabili axhunywe ngezintambo zangaphandle ngesikulufu.

Izici zesakhiwo Lolu chungechunge lwe-fuse luqukethe isixhumanisi se-fuse, kanye nesiphathi se-fuse (isisekelo se-fuse, ingxenye yokulayisha ye-fusion).

Isixhumanisi se-fuse siqukethe ithubhu le-fuse, i-melt, kanye ne-filler. Ukuncibilika kwesigaba esiguquguqukayo sebhande lethusi elihlanzekile noma ucingo kuvalwa kuthubhu le-fuse elinamandla aphezulu, lapho kugcwaliswa kuthubhu le-fuse ngobumsulwa obukhulu besihlabathi se-quartz esicutshungulwa ngamakhemikhali njengendawo yokuxhuma.

Izinhlangothi ezimbili zokuncibilika zishintshwa zibe yi-spot weld ukuze zibe kagesi eqinile futhi zixhunywe nepuleti lokugcina (noma ipuleti lokuxhuma), elakha i-cylindrical cap fuse. Isibambi se-fuse sakhiwe isisekelo se-fuse kanye nengxenye yokulayisha ye-fusion, sibonakala njengesakhiwo sohlobo oluphelele lokuvala lapho i-fuse isebenza.

Kungaba khona isibani sokukhombisa ukuhlanganiswa kwe-fusion engxenyeni yokulayisha i-fusion, isibani sokukhombisa sizokhanya lapho isixhumanisi se-fuse sihlanganiswa ukuze kukhunjulwe umqhubi. Isibambi sifakwe ngesitimela esijwayelekile se-TH35, kulula futhi kulula. I-terminal yokuxhuma yezinhlangothi ezimbili ixhunywe nentambo yangaphandle ngesikulufu.
