Okokuqala, sinokujonga kwiimpawu ze-fuses zombane ophezulu.
Njengoko sisazi, umsebenzi weiifusi zombane ophezulukukukhusela isekethe.Okokuthi, xa i-current in circuit idlula ixabiso elichaziweyo, inyibilika ngaphakathi kwe-fuse iya kuvelisa uhlobo lobushushu ukuphula isiphaluka.Ke ngoko, kwizinto zokudibanisa amandla ombane aphezulu, kufuneka zibe nendawo enyibilikayo ephantsi, kulula ukucima iimpawu ze-arc.Ngokubanzi kubandakanywa ubhedu, isilivere, i-zinc, ilothe, i-alloy tin alloy kunye nezinye izinto.Ngenxa yokuba iindawo zokunyibilika kwezi zixhobo zihlukile, izinto ezahlukeneyo ziyafuneka kwimisinga eyahlukeneyo.Ubushushu babo bokunyibilika buhambelana ne-1080 ℃, 960 ℃, 420 ℃, 327 ℃ kunye ne-200 ℃ ngokulandelelanayo.
Imiyalelo yokusetyenziswa kwezi zixhobo zahlukeneyo imi ngolu hlobo lulandelayo:
1. Indawo yokunyibilikisa i-zinc, ilothe, i-lead-tin alloy kunye nezinye izinyithi ziphantsi, kodwa ukuxhathisa kukhulu.Ngoko ke, ukusetyenziswa kwe-fuse indawo ye-cross-sectional inkulu, umphunga wesinyithi owenziweyo xa i-fusing ingenakulungele ukucima i-arc.Isetyenziswa kakhulu kwisekethe engaphantsi kwe-1kV.
2. Ubhedu kunye nesilivere zineendawo eziphezulu zokunyibilika, kodwa ukuxhathisa okuncinci kunye nokuhamba kakuhle kombane kunye ne-thermal conductivity.Ngoko ke, ukusetyenziswa kwe-fuse cross-sectional area incinci, umphunga wesinyithi owenziweyo xa i-fusing incinci, kulula ukucima i-arc.Inokusetyenziswa kwi-voltage ephezulu, isiphaluka esiphezulu sangoku.Nangona kunjalo, ukuba i-current inkulu kakhulu, ukushisa kwexesha elide kuphezulu kakhulu, kulula ukubangela umonakalo kwamanye amacandelo kwi-fuse.Ukuze wenze i-fuse encibilike ngokukhawuleza, kufuneka ihambe nge-current enkulu, ngaphandle koko iya kwandisa ixesha le-fuse, elingathandekiyo kwizixhobo zokukhusela.Ukuze kupheliswe le ntsilelo, i-tin okanye i-pellet ye-lead isoloko i-welded kwi-copper okanye i-silver melt ukunciphisa ukushisa okunyibilikayo kunye nokuphucula ukusebenza kokukhusela ukunyibilika.
