Kukhazikitsa Fuse ya Mtundu Wotayira

Fuse yotaya ndi mzere wa nthambi wa mizere yogawa ya 10 kV ndipo chosinthira chogawa ndi chosinthira choteteza cha short-circuit chomwe chimagwiritsidwa ntchito kwambiri. Chimagwira ntchito bwino komanso mopanda mavuto, kuti chigwirizane ndi malo akunja okhala ndi mawonekedwe amphamvu, chimagwiritsidwa ntchito kwambiri mu mizere yogawa ya 10kV ndi mbali yayikulu ya chosinthira chogawa ngati chitetezo ndi zida, chimagwira ntchito ndi. Chimayikidwa mu mzere wa nthambi ya mzere wogawa wa 10kV, chimachepetsa kuzima kwa magetsi, chifukwa chili ndi malo owonekera olumikizirana, chili ndi ntchito yolekanitsa chosinthira, chimapanga malo ogwirira ntchito otetezeka ku gawo losamalira la mzere ndi zida, ndikuwonjezera kumverera kwa chitetezo cha ogwira ntchito okonza. Choyikidwa pa chosinthira chogawa, chingagwiritsidwe ntchito ngati chitetezo chachikulu cha ma transformer ogawa, kotero, mu mizere yogawa ya 10kV ndi ma transformer ogawa akhala otchuka.

Mfundo yake yogwirira ntchito ndi iyi: chubu cha fuse kumapeto onse awiri a cholumikizira chosuntha chomwe chimamangirira fuse (kusungunuka), cholumikizira chosuntha chimakankhira "duckbill" bulge, phosphorous, mbale yamkuwa, ndi zina zotero. Chopangidwa ndi kukhudzana kosasunthika pamwamba pa cholumikizira chosuntha, motero chubu cha fuse chimamangiriridwa mwamphamvu pa "duckbill". Pamene mphamvu yafupikitsa kudzera mu fuse yaphulika, kupingasa, chubu cha fuse chomwe chili ndi ulusi wokhuthala pansi pa mphamvu ya arc chimapanga mpweya wambiri chifukwa cha kutsekedwa kwa chitoliro cha fuse, mpweya womwe umapita kumapeto kwa kupopera, umaphulika arc. Chifukwa cha fuse, mphamvu ya fuse yosuntha yolumikizira fuse imatayika, chubu cha fuse chosasunthika cholumikizira chimachepa, ndipo pansi pake, chubu cha fuse chimagwa mofulumira, dera limatsekedwa, kuchotsa gawo lolakwika la mzere kapena kulephera kwa zida.
