Ama-Fuse: Isihluthulelo sokunika amandla izinhlelo zikagesi
Emkhakheni wobunjiniyela kagesi kanye nezinhlelo zamandla, igama elithi “fuse” libaluleke kakhulu. Amafuse ayizingxenye ezibalulekile ezidlala indima ebalulekile ekuvikeleni amasekethe nezinhlelo kumasekethe adlulayo kanye nama-short circuits. Asebenza njengedivayisi yokuphepha, ephazamisa ukuhamba kukagesi uma udlula izinga elinqunyiwe, ngaleyo ndlela evimbela ukulimala kwezingxenye zikagesi futhi eqinisekisa ukuphepha kohlelo kanye nabasebenzisi balo.
Isimiso esiyisisekelo ngemuva kwama-fuse silula kodwa siyasebenza. Siqukethe umucu omncane wensimbi, ovame ukwenziwa ngethusi noma i-aluminium, owenzelwe ukuncibilikisa nokuphula isekethe lapho ugesi udlula umthamo olinganiselwe we-fuse. Lesi senzo sinqamula ngempumelelo ukunikezwa kwamandla futhi sivimbele ukugeleza kogesi okuqhubekayo, ngaleyo ndlela sivikele imishini kagesi futhi sivimbele izingozi ezingaba khona njengomlilo noma ukushaqeka kukagesi.
Ama-fuse eza ngezinhlobo eziningi nosayizi, ngalinye lenzelwe uhlelo lokusebenza oluthile kanye nesilinganiso samanje. Izinhlobo ezivame kakhulu zifaka phakathi ama-fuse e-cartridge, ama-chip fuse, kanye nama-fuse angasethwa kabusha. Ama-fuse e-barrel anesimo esiyindilinga futhi avame ukusetshenziswa ezinhlotsheni zezimboni kanye namandla aphezulu. Ama-fuse e-chip, ngakolunye uhlangothi, avame ukutholakala ezimotweni kanye nasezintweni zikagesi zabathengi futhi anomzimba wepulasitiki oyisicaba kanye nama-prong amabili ukuze kube lula ukuwafaka. Ama-fuse angasethwa kabusha, aziwa nangokuthi amadivayisi e-Polymer Positive Temperature Coefficient (PPTC), aklanyelwe ukusetha kabusha ngokuzenzakalelayo lapho isimo sephutha sisuswa, okuhlinzeka ngesisombululo esilula nesingabizi kakhulu sokuvikela ugesi ngokweqile.
Ukukhetha i-fuse efanele yohlelo oluthile kubalulekile ekuqinisekiseni ukusebenza okuthembekile nokuphephile kohlelo lwakho lukagesi. Izici ezifana nesilinganiso samanje esiphezulu, isilinganiso samandla kagesi, ikhono lokuphazamisa kanye nesikhathi sokuphendula kudingeka zicatshangelwe ngokucophelela lapho kukhethwa i-fuse. Izilinganiso ze-fuse kumele zihambisane nezidingo zesekethe ukuze zinikeze isivikelo esisebenzayo ngaphandle kokuphazamisa ukusebenza kohlelo.
Ngaphezu kwemisebenzi yazo yokuvikela, ama-fuse angasetshenziswa njengamathuluzi okuxilonga ukuze kutholakale amaphutha ngaphakathi kwezinhlelo zikagesi. Uma i-fuse ishaya, kubonisa ukuthi kukhona i-overcurrent noma i-short circuit. Ngokuhlola nokufaka esikhundleni ama-fuse aqhumile, onjiniyela nochwepheshe bangathola futhi balungise inkinga eyisisekelo, baqinisekise ukuthembeka okuqhubekayo nokuphepha kwesistimu yakho kagesi.
Njengoba ubuchwepheshe buthuthuka, ama-fuse esimanje ayaqhubeka nokuguquka ukuze ahlangabezane nezidingo zezinhlelo zikagesi eziyinkimbinkimbi. Isibonelo, ama-fuse ahlakaniphile manje afakwe izinzwa namakhono okuxhumana ukuze anikeze ukuqapha ngesikhathi sangempela kanye nesibonakaliso sesimo esikude. Lawa ma-fuse ahlakaniphile ahlinzeka ngokuvikelwa okuthuthukisiwe kanye nokuxilonga, okwenza kube lula ukugcinwa okusheshayo kanye nokuthuthukisa ukuthembeka kohlelo.
Ngamafuphi, ama-fuse ayizingxenye ezibalulekile ezinhlelweni zikagesi futhi angumugqa wokuqala wokuzivikela emaphutheni okusebenzisa ugesi ngokweqile kanye namaphutha okujikeleza okufushane. Indima yawo ekuvikeleni imishini, ekuvimbeleni izingozi kanye nokwenza kube lula ukuxilongwa kwamaphutha ayinakweqiswa. Njengoba izinhlelo zikagesi ziqhubeka nokuthuthuka, ukuthuthukiswa kobuchwepheshe be-fuse obusha kuzothuthukisa kakhulu ukuphepha nokuthembeka kokusatshalaliswa kwamandla nokusetshenziswa kwawo. Ngakho-ke, ukuqonda ukubaluleka kwama-fuse nokukhetha ama-fuse afanele okusetshenziswa ngakunye kubalulekile ekuqinisekiseni ukuthi izinhlelo zikagesi zisebenza kahle nangokuphephile.
