Incazelo emfushane:

Ukusika i-fuse ephumayo kanye nokusika i-fuse yokushintsha umthwalo kuyithuluzi elingaphandle elivikela amandla kagesi aphezulu. Ukuze ixhunywe nesiphakeli esingenayo sokusabalalisa, i-transformer noma imigqa yokusabalalisa. Ivikela kakhulu i-transformer noma imigqa ekujikelezeni okufushane kanye nokulayishwa ngokweqile kanye no-ON/OFF ukulayisha okwamanje. I-dropout fuse cutout yakhiwe ngezisekelo ze-insulator kanye neshubhu ye-fuse. Othintana nabo abanganyakazi bahlanganiswe ezinhlangothini ezimbili zosekelo lwe-insulator, othintana nabo abahambayo bafakwa emaphethelweni okudonsa eshubhu le-fuse. I-Fuse tube yakhiwe ngaphakathi kwe-arc extinguishing tube. I-Outlineer phenolic compound paper tube noma i-epoxyglasstube. Ukusika i-fuse yokushintsha ukulayisha kunikeza othintana nabo abaphoqelelwe bokunwebeka nesihlangu se-arc ukuze ucime ukulayisha ukulayisha. Esimeni esivamile sokusebenza, isixhumanisi se-fuse siqiniswa ishubhu ye-fuse igxilile ukuze yakhe indawo eseduze. Uma kwenzeka iphutha lesistimu, i-fault current izovumela i-fuse incibilike ngokushesha futhi ilethwe i-arc kagesi, evumela ishubhu lokucisha i-arc lishise futhi kuxazululwe igesi eningi. Lokhu kuzokhiqiza umfutho ophezulu kubhavu, futhi ushaye kanye neshubhu, bese i-arc izonwetshwa futhi icime. Ngemva kokuncibilika kwesixhumanisi se-fuse, othintana nabo abanyakazayo abanawo amandla aqinisiwe, idivayisi yokukhiya ikhulula i-fuse, ukuphuma kweshubhu ye-fuse, ukusika manje kusendaweni evulekile. Uma idinga ukucisha phakathi nokulayishwa kwe-cutout, sebenzisa ibhola le-insulate yokusebenza donsa othintana naye onyakazayo, manje othintana naye oyinhloko kanye noxhumana nabo abamile abasizayo basathintana. Ngenkathi idonsa, othintana nabo abasizayo bayahlukaniswa, bese kwenzeka i-arc kagesi phakathi koxhumana nabo abasizayo, i-arc inwetshwa ku-arc shield, ngesikhathi esifanayo isihlangu se-arc siqhuma igesi, lapho ukulayishwa kwamanje, kuvumela ukucisha.
