Q: Ingakanani i-voltage ephezulu kwi-block ye-fuse terminal ye-5x20mm?
A: Iifusi zekhatriji eziqhelekileyo ze-5x20mm zilinganiswe kwiivolthi zenkqubo ukuya kuthi ga kwi-250V AC okanye kwi-DC yi-IEC 60127. Uninzi lweeblokhi zesiphelo sefusi ezisemgangathweni zilinganiswe kwi-250V AC ubuncinci, kwaye uninzi lwazo lulinganiswe kwi-400V AC ukubonelela ngemargin yezicelo zenkqubo yokusasazwa kwemizi-mveliso. Soloko uqinisekisa umlinganiselo wevolthi yefusi kunye neblokhi yesiphelo ngokuchasene nomlinganiselo ophezulu wevolthi yenkqubo kwisicelo sakho.

Q: Ndingayikhetha njani ireyithingi yangoku echanekileyo yefuse ye-5x20mm kwisekethe yam?
A: Umlinganiselo wamandla e-fuse kufuneka ukhethwe ukuba ube ngaphezulu komlinganiselo oqhelekileyo womthwalo opheleleyo wesekethe kodwa ube ngaphantsi komlinganiselo wamandla onokubangela umonakalo kwiikhontraktha okanye kwizixhobo ezikhuselweyo. Isikhokelo esiqhelekileyo kukukhetha umlinganiselo we-fuse we-125% ukuya kwi-150% womlinganiselo oqhelekileyo womthwalo opheleleyo. Kwiisekethe ezinee-motors okanye ii-transformers, jonga umlinganiselo wamandla ongenayo ngexesha lokuqalisa ukuqinisekisa ukuba i-fuse ayivuthuzi ngexesha lokusebenza okuqhelekileyo. Xa ungaqinisekanga, jonga izikhokelo zokulungelelanisa ukhuseleko lomenzi wezixhobo okanye uqhagamshelane nonjineli wombane ofanelekileyo.

Q: Ndingayivavanya njani ukuba ifuse yekhatriji ye-5x20mm isasebenza kakuhle?
A: I-cartridge fuse inokuvavanywa nge-multimeter esetiweyo yokulinganisa ukuqhubeka okanye ukumelana. I-fuse elungileyo iya kubonisa ukufundwa kokumelana okuphantsi (ngesiqhelo ngaphantsi kwe-1 ohm kwi-fuse eyi-5x20mm kubushushu begumbi). I-open fuse iya kubonisa ukumelana okungapheliyo (akukho ukuqhubeka). Qaphela ukuba ezinye iintlobo ze-fuse—ingakumbi ii-fuse ezisebenza ngokukhawuleza kakhulu ezine-elements ezintle kakhulu—zinokubonisa ukumelana okuphezulu kancinci nokuba zilungile, kodwa kufuneka ziqhubeke nokubonisa ukuqhubeka. I-fuse evulekileyo ngokuqinisekileyo ihlala ingaphumeleli kwaye kufuneka itshintshwe.
