Isingeniso sefusi yamandla

Umgomo we-fuse yamandla

I-fuse yamandla ingenye yama-fuse, okubhekisela kumshini kagesi ohlanganisa ukuncibilika nokushisa okukhiqizwa yiwo futhi unqamule isekethe lapho ugesi udlula inani elithile. I-fuse iyisivikelo samandla esenziwa ngokusebenzisa ukushisa okukhiqizwa yiwo ukuze kuncibilikiswe ukuncibilika ngemva kokuba ugesi udlula inani elithile isikhathi esithile, ngaleyo ndlela kunqamule isekethe.

Umgomo wokusebenza wefusi ulula uma uqhathaniswa nesikhathi. Uma ugesi uphakeme, isikhathi sokuxuba noma sokuvula sifushane. Ukushabalaliswa kwamandla kwefusi kuhambisana nesikwele sogesi ngefusi. Uma ukusetshenziswa kwamandla kuphezulu kakhulu, ifusi iyavunguza. Lesi sici sisebenza futhi kuma-harnesses avikelwe yifusi. Uma ukushisa okukhiqizwayo kudlula ukushisa okuphelile, izinga lokushisa lefusi lizokhuphuka. Lapho izinga lokushisa lenyuka lize lifike endaweni yokuncibilika kwefusi yefusi, ifusi izovunguzwa, okungukuthi, isekethe izonqanyulwa ukuze ivikelwe.

Ama-fuse asetshenziswa kabanzi ezinhlelweni zokusabalalisa amandla kagesi aphezulu naphansi kanye nezinhlelo zokulawula kanye nemishini kagesi. Njengesivikelo se-short circuit kanye ne-overcurrent, ingenye yamadivayisi okuvikela asetshenziswa kakhulu.

Ukuhlukaniswa kwama-fuse kagesi

Ama-fuse kagesi ayingxenye yama-fuse (ama-fuse), angahlukaniswa ngama-fuse okuvikela e-semiconductor, ama-fuse e-DC, ama-fuse akhethekile, ama-fuse ajwayelekile kanye nama-disconnector e-fuse.

Izici zesakhiwo sefusi yamandla

Isakhiwo sefusi yamandla sifana kakhulu nesefusi. Yakhiwe kakhulu ngokuncibilika, igobolondo kanye nokusekela, lapho ukuncibilika kuyisici esibalulekile sokulawula izici zokuhlanganisa. Izinto, usayizi kanye nesimo sokuncibilika kunquma izici zokuhlanganisa. Izinto zokuncibilika zihlukaniswe ngezigaba ezimbili: iphuzu lokuncibilika eliphansi kanye nephuzu lokuncibilika eliphezulu. Izinto zokuncibilika eziphansi njenge-lead kanye ne-lead alloys zinephuzu lokuncibilika eliphansi futhi kulula ukuzihlanganisa. Ngenxa yokumelana kwazo okukhulu, usayizi wesigaba sokuncibilika mkhulu, futhi kukhiqizwa umusi wensimbi omningi ngesikhathi sokuhlanganisa. Kufanelekela kuphela ukuhlanganisa ngomthamo wokuphuka ophansi. Izinto zokuncibilika eziphakeme njengethusi nesiliva zinephuzu lokuncibilika eliphezulu futhi akulula ukuzihlanganisa, kodwa ngenxa yokumelana kwazo okuphansi, zingenziwa zibe yizilinganiso ezincane zokunqamula kunephuzu lokuncibilika eliphansi elincibilikayo, futhi zikhiqize umusi wensimbi omncane uma zihlanganiswa, ofanele amaphuzu aphezulu okuphuka. Ukuma kokuncibilika kuhlukaniswe ngezinhlobo ezimbili: i-filament kanye neribhoni. Ukushintsha ukuma kwesigaba esiguquguqukayo kungashintsha kakhulu izici zokuhlanganisa zefusi.
