Intshayelelo yefusi yamandla

Umgaqo wefusi yamandla

I-fuse yamandla yenye yee-fuse, ebhekisa kwisixhobo sombane esidibanisa i-melt nobushushu obuveliswa yiyo kwaye siqhawule isekethe xa i-current idlula ixabiso elithile. I-fuse sisikhuseli samandla esenziwe ngokusebenzisa ubushushu obuveliswa yiyo ukuze bunyibilike i-melt emva kokuba i-current idlula ixabiso elithile kangangexesha elithile, ngaloo ndlela siqhawule isekethe.

Umgaqo wokusebenza wefuse yi-I2R elula xa ithelekiswa nexesha. Okukhona umbane uphezulu, kokukhona ixesha lokudibanisa okanye lokuvula lifutshane. Ukuchithwa kwamandla kwefuse kuhambelana nesikwere sombane ngefuse. Xa ukusetyenziswa kwamandla kuphezulu kakhulu, ifuse iyavuthuza. Olu phawu lukwasebenza nakwii-harnesses ezikhuselwe yifuse. Ukuba ubushushu obuvelisiweyo budlula ubushushu obuphelileyo, ubushushu befuse buya kwanda. Xa ubushushu bunyuka buye kwinqanaba lokunyibilika kwefuse yefuse, ifuse iya kuvuthuzwa, oko kukuthi, isekethe iya kunqunyulwa ukuze ikhuseleke.

Iifusi zisetyenziswa kakhulu kwiinkqubo zokusasazwa kwamandla aphezulu naphantsi kunye neenkqubo zolawulo kunye nezixhobo zombane. Njengesikhuselo se-short circuit kunye ne-overcurrent, sesinye sezixhobo zokukhusela ezisetyenziswa kakhulu.

Uhlu lweefusi zamandla

Iifusi zamandla ziyinxalenye yeefusi (iifusi), zinokwahlulwa zibe ziifusi zokukhusela ze-semiconductor, iifusi ze-DC, iifusi ezikhethekileyo, iifusi zenjongo jikelele kunye nee-disconnectors zefusi.

Iimpawu zesakhiwo sefusi yamandla

Ulwakhiwo lwefuse yamandla lufana kakhulu nolwefuse. Iquka kakhulu ukunyibilika, iqokobhe kunye nenkxaso, apho ukunyibilika yeyona nto iphambili yokulawula iimpawu zokuxuba. Izinto, ubungakanani kunye nokuma kokunyibilika kumisela iimpawu zokuxuba. Izinto zokunyibilika zahlulwe zibe ziindidi ezimbini: indawo yokunyibilika ephantsi kunye nendawo yokunyibilika ephezulu. Izinto eziphantsi zokunyibilika ezifana ne-lead kunye ne-lead alloys zinendawo yokunyibilika ephantsi kwaye kulula ukuzihlanganisa. Ngenxa yokumelana kwazo okukhulu, ubungakanani obunqamlezileyo bokunyibilika bukhulu, kwaye umphunga wesinyithi omninzi wenziwa ngexesha lokuxuba. Ifanelekile kuphela ukuxuba ngomthamo ophantsi wokuqhekeza. Izinto eziphezulu zokunyibilika ezifana nobhedu nesilivere zinendawo yokunyibilika ephezulu kwaye azilula ukuzihlanganisa, kodwa ngenxa yokumelana kwazo okuphantsi, zinokwenziwa zibe ziimilinganiselo ezincinci zokunqumla kuneendawo eziphantsi zokunyibilika ezinyibilikayo, kwaye zivelise umphunga wesinyithi omncinci xa zidibene, ezifanelekileyo kwiindawo eziphezulu zokuqhekeka. Ubume bokunyibilika bahlulwe baba ziintlobo ezimbini: i-filament kunye neribhoni. Ukutshintsha imo yecandelo eliguquguqukayo kunokutshintsha kakhulu iimpawu zokuxuba zefuse.
