IiFuses: Isitshixo sokunika amandla iinkqubo zombane
Kwicandelo lobunjineli bombane kunye neenkqubo zamandla, igama elithi "fuse" libaluleke kakhulu. Iifuse zizinto ezibalulekileyo ezidlala indima ebalulekileyo ekukhuseleni iisekethe kunye neenkqubo kwi-overcurrent kunye nee-short circuits. Zisebenza njengesixhobo sokhuseleko, ziphazamisa ukuhamba kombane xa udlula kwinqanaba elimiselweyo, ngaloo ndlela zithintela ukonakala kwezixhobo zombane kwaye ziqinisekisa ukhuseleko lwenkqubo kunye nabasebenzisi bayo.
Umgaqo osisiseko weefusi ulula kodwa uyasebenza. Uqulathe umcu omncinci wesinyithi, odla ngokwenziwa ngobhedu okanye i-aluminium, owenzelwe ukunyibilikisa nokuphula isekethe xa umbane udlula amandla efusi alinganisiweyo. Esi senzo siqhawula ngokufanelekileyo umbane kwaye sithintele ukuhamba kombane okungakumbi, ngaloo ndlela sikhusela izixhobo zombane kwaye sithintele iingozi ezinokubakho ezifana nomlilo okanye ukutshayiswa kombane.
Iifusi ziza ngeentlobo ezahlukeneyo kunye nobukhulu, nganye yenzelwe usetyenziso oluthile kunye novavanyo lwangoku. Ezona ntlobo zixhaphakileyo ziquka iifusi zekhatriji, iifusi zeetship, kunye neefusi ezibuyiselwayo. Iifusi zebhareli zimile okwesilinda kwaye zihlala zisetyenziswa kwizicelo zoshishino kunye namandla aphezulu. Iifusi zeetship, kwelinye icala, zihlala zifumaneka kwiimoto nakwii-elektroniki zabathengi kwaye zinomzimba weplastiki othe tyaba kunye neeprong ezimbini ukuze kube lula ukuzifaka. Iifusi ezibuyiselwayo, ezaziwa ngokuba zizixhobo zePolymer Positive Temperature Coefficient (PPTC), zenzelwe ukuseta ngokuzenzekelayo xa imeko yempazamo isusiwe, zibonelela ngesisombululo esilula nesingabizi kakhulu sokukhusela umbane ogqithisileyo.
Ukukhetha ifusi efanelekileyo yesicelo esithile kubalulekile ukuqinisekisa ukusebenza okuthembekileyo nokukhuselekileyo kwenkqubo yakho yombane. Izinto ezinje ngomlinganiselo ophezulu wamandla ombane, umlinganiselo wombane, amandla okuphazamisa kunye nexesha lokuphendula kufuneka ziqwalaselwe ngononophelo xa ukhetha ifusi. Umlinganiselo wefusi kufuneka uhambelane neemfuno zesekethe ukuze unike ukhuseleko olusebenzayo ngaphandle kokuchaphazela ukusebenza kwenkqubo.
Ukongeza kwimisebenzi yazo yokukhusela, iifusi zingasetyenziswa njengezixhobo zokuxilonga ukuchonga iimpazamo kwiinkqubo zombane. Xa ifusi ivuthuza, ibonisa ukuba kukho i-overcurrent okanye i-short circuit kwisekethe. Ngokuhlola nokutshintsha iifusi ezivuthuzayo, iinjineli kunye neengcali zinokufumana kwaye zilungise ingxaki engundoqo, ziqinisekise ukuthembeka okuqhubekayo kunye nokhuseleko lwenkqubo yakho yombane.
Njengoko ubuchwepheshe buqhubeka, iifusi zanamhlanje ziyaqhubeka nokukhula ukuze zihlangabezane neemfuno zeenkqubo zombane ezintsonkothileyo. Umzekelo, iifusi ezikrelekrele ngoku zixhotyiswe ngezixhobo zokubona kunye nonxibelelwano ukuze zibonelele ngokubekwa esweni ngexesha langempela kunye nokubonisa imeko ekude. Ezi fusi ezikrelekrele zibonelela ngokhuseleko oluphuculweyo kunye nokuxilongwa, okuvumela ukugcinwa kwangaphambili kunye nokuphucula ukuthembeka kwenkqubo.
Ngamafutshane, iifusi zizinto ezibalulekileyo kwiinkqubo zombane kwaye ziyindlela yokuqala yokuzikhusela kwiimpazamo zombane ogqithisileyo kunye neze-short-circuit. Indima yazo ekukhuseleni izixhobo, ukuthintela iingozi kunye nokwenza kube lula ukuxilongwa kweempazamo ayinakugqithiswa. Njengoko iinkqubo zombane ziqhubeka zihambela phambili, uphuhliso lwetekhnoloji entsha yefusi luya kuphucula ngakumbi ukhuseleko kunye nokuthembeka kokusasazwa kwamandla kunye nokusetyenziswa kwawo. Ke ngoko, ukuqonda ukubaluleka kweefusi kunye nokukhetha iifusi ezifanelekileyo kwisicelo ngasinye kubalulekile ukuqinisekisa ukuba iinkqubo zombane zisebenza ngokufanelekileyo nangokukhuselekileyo.
