Umsebenzi Wokuzivuselela We-Fuse

Uma ukwehluleka kokushisa ngokweqile kuqedwa, isici se-fuse singabuyiselwa ngokuzenzakalelayo esimweni sokumelana okuphansi. Lokhu kugwema izinguquko zokugcinwa kanye nezimo zokuvula nokuvala kwezihibe ezilandelanayo ezingabangela umonakalo wesekethe. Ngenxa yokwenziwa kwayo okukhethekile, i-fuse yokusetha kabusha inemisebenzi emibili yokuvikela i-overcurrent kanye ne-overheating kanye nokubuyisa okuzenzakalelayo. I-fuse yokuzivuselela yenziwe ngengxube yama-polymers nezinto zokuqhuba. I-fuse yokusetha kabusha i-polymer iqukethe i-polymer resin matrix kanye ne-conductive particle esatshalaliswa kuyo. Ngaphansi kwezimo ezivamile, izinhlayiya eziqhubayo ku-resin matrix zakha indlela ye-chain conductive, futhi i-polymer ingasetha kabusha i-fuse ukuze iveze impedance ephansi (a). Lapho kwenzeka ugesi osesekethe, ukushisa okukhiqizwa ugesi ophezulu ogeleza nge-polymer kungasetha kabusha i-fuse kubangela ukuthi ivolumu ye-polymer resin substrate ikhule, inqume indlela ye-chain conductive eyakhiwe yizinhlayiya eziqhubayo, okuholela ekwandeni okusheshayo kwe-impedance ngakho-ke, i-polymer ingasetha kabusha i-fuse ingadlala umphumela wokuvikela i-overcurrent kusekethe (b). Ngemva kokususwa kokwehluleka, i-resin iyaphola futhi icwebezele futhi, ivolumu iyancipha, izinhlayiya eziqhubayo zakha isiteshi esiqhubayo futhi, futhi i-polymer ingabuyisela i-fuse ku-impedance ephansi. Uma iqhathaniswa nama-fuse avamile, inezinzuzo zokuziphindaphinda, usayizi omncane noqinile.
