Ukusika i-fuse ephumayo kanye nokusika i-fuse yokushintsha umthwalo kuyidivayisi evikela amandla kagesi aphezulu esetshenziswa ngaphandle, i-Tobe exhunywe ne-incomin-g feeder yesiguquli sokusabalalisa noma imigqa yokusabalalisa, ivikela ikakhulukazi i-transformer noma imigqa ekusekeni okufushane nokulayishwa ngokweqile, kanye nokuvula/ukuvala ukulayisha. ,okwamanje,I-drop-out ye-fuse cutout yenziwe ngezisekelo ze-insulate insulator kanye neshubhu ye-fuse, othintana nabo abangaguquki bamiswe ezinhlangothini ezimbili zokusekela isivikelo kanye nokuxhumana okunyakazayo kufakwa emaphethelweni amabili eshubhu le-fuse,Ishubhu le-Fuse lakhiwe ngaphakathi kwe-arcexting tube.Outer phenolic compound paper tube noma epoxy glasstube,Layisha switching fuse cutout inikeza okuqinisiwe koxhumana nabo okunwebekayo kanye ne-arc-extinguishing exclosure switching on-off loading current.Ngokujwayelekile ukusebenza nge-fuselink kuyaqiniswa ishubhu ye-fuse iyalungiswa ukuze yakhe indawo eseduze. Uma kwenzeka amaphutha esistimu, umphumela wamanje oyiphutha uncibilika ngokushesha bese uthatha ucezu lukagesi, okuvumela ishubhu lokucisha i-arc ukuba lishise futhi liqhume kakhulu. yegesi, i-Th-os izokhiqiza umfutho ophezulu futhi ngaphansi kwayo ihambisana ne-tube.Ngemuva kokuthi i-fuselink incibilike incibilikisa othintana naye onyakazayo ayisenawo amandla aqinisiwe futhi, i-mecganismis ikhiyiwe futhi i-fuse tube iphuma, i-Cutout manje isisendaweni evulekile, Uma idinga ukucisha ngesikhathi sokulayisha okusikiwe, isebenze-noma izodonsa othintana naye onyakazayo nge-insulating operation bar, i-atits iqala ukuthintana okuyinhloko kanye ne-axiliary static contactic contactedst-ill, Ngenkathi idonsa othintana naye oyisizayo ihlukaniswa phakathi koxhumana nabo abasizayo kuba khona i-arc kagesi futhi i-arc izokwelulwa esikhaleni esivale i-arc-cima i-arc futhi okwamanje iqhume igesi ukuze iqhume. i-arc ngesikhathi sokudlula uziro.
