Ukusika i-fuse okuphumayo kanye nokusika i-fuse yokushintsha umthwalo kuyidivayisi evikela amandla kagesi aphezulu esetshenziswa ngaphandle, i-Tobe connecte ne-incomin-g feeder yesiguquli sokusabalalisa noma imigqa yokusabalalisa, ivikela ikakhulukazi imigqa ye-transformeror ekujikelezweni okufushane nokulayishwa ngokweqile, kanye nokulayisha / ukuvala ukulayisha, okwamanje, ukusika kwe-fuse okuphumayo kwenziwa nge-insulat insulator, izisekelo ezisekela amashubhu amabili kanye ne-fuse ehlangothini elisekelayo. ukuthintana kufakwe emaphethelweni amabili e-fuse tube, i-Fuse tube yakhiwa ngaphakathi kwe-arcexting tube. Ishubhu yephepha ehlanganisiwe ye-phenolic yangaphandle noma i-epoxy glasstube, ukunqamula ukushintshwa kwe-fuse kokulayisha kunikeza oxhumana nabo abanwebekayo abasizayo kanye nokuvezwa kwe-arc-ecimayo ukuze kucishwe amandla okulayisha.
Ngokujwayelekile ukusebenza nge-fuselink kuqiniswe ishubhu ye-fuse iyalungiswa ukuze yakhe indawo eseduze, Uma kwenzeka amaphutha esistimu, umphumela wamanje wephutha ku-fuse uncibilike ngokushesha futhi uthathe ucezu lukagesi, okuvumela ishubhu lokucisha i-arc lishiswe futhi liqhume i-lotofgas, i-Th-os izokhiqiza umfutho ophezulu futhi ngaphansi kwawo kuhambisana namashubhu ancibilikisiwe futhi axhumeke futhi I-fuse tube drop out, i-Cutoutnow isendaweni evulekile, Lapho idinga ukucishwa ngesikhathi ilayisha ukunqamula, i-opharetha-noma izodonsa othintana naye onyakazayo ngebha ye-insulating, iqale ukuthintana naye oyinhloko kanye nokuxhumana okuqinile okuxhumene kakhulu, ngenkathi idonsa othintana naye ihlukaniswa phakathi koxhumana nabo abasizayo lapho kwenzeka i-arc-exercishi kagesi. igebe lendawo ebiyelwe kanye nokuqhuma kwe-arc-exting gas ukuze kuqhunyiswe i-arc phakathi noziro wamanje odlulayo
