I-fuse yokuyekai-cutout kanye ne-load switching fuse cutout isetshenziswa ngaphandleidivayisi yokuvikela i-voltage ephezulu, I-Tobe ixhuma nge-incomin-g feeder yesiguquli sokusabalalisa noma imigqa yokusabalalisa, ivikela ikakhulukazi imigqa ye-transformer kusuka kumjikelezo omfushane nokulayisha ngokweqile, kanye nokulayisha / ukuvala ukulayisha, okwamanje, i-Drop-out fuse cutout yakhiwe ngezisekelo ze-insulat insulator kanye ne-fuse tube, othintana nabo abangashintshi bagxilwe ezinhlangothini ezimbili zokusekelwa kwe-insulator kanye nokuxhumana okuhambayo kwe-fuse kufakwe kumashubhu amabili.Fusetube yakhiwe ngaphakathi 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
