Kufotokozera Kwachidule:

Kudulira kwa fusesi kosiya ndi kutsika kwa fusesi ndi zida zoteteza panja zamphamvu kwambiri. Kulumikizidwa ndi ma feeder omwe akubwera ogawa, ma transfoma kapena mizere yogawa. Imateteza kwambiri thiransifoma kapena mizere kuchokera kufupipafupi ndikudzaza mochulukira komanso ON/OFF kutsitsa pakali pano. Dropout fuse cutout imapangidwa ndi zothandizira zotetezera komanso chubu cha fuse. Kulumikizana kwa static kumakhazikika pa mbali ziwiri za chithandizo cha insulator, zosuntha zimayikidwa pamphepete mwa fuse chubu. Fuse chubu imapangidwa ndi chubu chozimitsa chamkati cha arc. Outlineer phenolic pawiri pepala chubu kapena epoxyglasstube. Load switching fuse cutout imapereka zolumikizira zotanuka zothandizira ndi chishango cha arc pozimitsa kutsitsa kwapano. Pamalo ogwirira ntchito, ulalo wa fusesi umakhazikika chubu la fusesi limakhazikika kuti likhale pafupi. Ngati dongosolo lalakwika, mphamvu yamagetsi imalola fuseyi kuti isungunuke nthawi yomweyo ndipo arc yamagetsi idzabweretsedwa, zomwe zimalola kuti chubu chozimitsira arc chitenthedwe ndikuthetsa gasi wambiri. Izi zidzatulutsa kuthamanga kwambiri mu chubu, ndikuwomba pamodzi ndi chubu, ndiyeno arc idzakulitsidwa ndikuzimitsidwa. Ulalo wa fusewu ukasungunuka, zolumikizira zilibe mphamvu zomangika, chida chotseka chimamasula fuse, chubu cha fuse chimasiya, cutout tsopano ili pamalo otseguka. Pakufunika kuzimitsa pa cutout Mumakonda, ntchito insulating opaleshoni mpira kukokera kukhudza kusuntha, tsopano kukhudzana waukulu ndi wothandiza malo amodzi kulankhula akadali kulankhula. Pamene kukoka, kulankhula wothandiza analekanitsidwa, ndiyeno Arc magetsi zinachitika pakati pa kukhudzana wothandiza, arc anawonjezera mu arc chishango, pa nthawi yomweyo ndi arc chishango kuphulika mpweya, pamene zimamuchulukira panopa, mulole izo kuzimitsa.
