Ifuse yokusika yokuyeka kunye nokutshintsha ukulayisha ifyuzi yokusika zezo zixhobo zokukhusela amandla ombane aphezulu. Ukudibaniswa ne-feeder engenayo ye-transformer yokusabalalisa okanye imigca yokusabalalisa ikhusela ngokukodwa i-transformer okanye imigca ukusuka kwisiphaluka esifutshane kunye nokugqithiswa, kunye nokulayisha / ukuvala ukulayisha okwangoku.I-fuse ye-cut-out cut-out fuse yenziwe ngenkxaso ye-insulat insulator kunye ne-tube ye-fuse, uqhagamshelwano lwe-static luqiniswe kumacala amabini enkxaso ye-insulator kunye noqhagamshelwano oluhambayo lufakwe kwiiphelo ezimbini ze-tube. ityhubhu yokucima i-arc, i-phenoilc yangaphandle ityhubhu yephepha okanye ityhubhu yeglasi ye-epoxy. Umthwalo wokutshintsha i-fuse ye-cutout ibonelela ngokunyanzeliswa koqhagamshelwano lwe-elastic auxil-iary kunye ne-arc yokucima i-enclosure yokucima / ukuvala ukulayisha ngoku.

Ngokuqhelekileyo ukusebenza nge-fuselink kuqinisiwe ityhubhu ye-fuse igxininiswe ukuze yenze indawo ekufutshane. Kwimeko apho inkqubo yenzeke iimpazamo, impazamo yangoku ibangela ukuba ifyuzi inyibilike ngoko nangoko kwaye yenzeke i-arc yombane, evumela ityhubhu yokucima i-arc ukuba ifudunyezwe kwaye idubule igesi eninzi. Oku kuya kuvelisa uxinzelelo oluphezulu kunye nokuvuthela i-arc kunye ne-tube.Emva kokuba i-fuselink inyibilika uqhagamshelwano oluhambayo alunamandla aqiniweyo kwakhona, inkqubo itshixiwe kwaye i-fuse tube iyancipha. I-cutout ngoku ikwindawo evulekileyo. Xa ifuna ukucima ngexesha lokulayishwa kwe-cutout, umsebenzisi uya kutsalela umnxeba oshukumayo nge-insulation bar yoqhagamshelwano, ekuqalekeni kwayo okungundoqo kuqhagamshelwano olusisigxina kunye noqhagamshelwano olusisigxina olusisigxina. Ngelixa utsala uqhagamshelwano oluncedisayo lwahlulwe phakathi koqhagamshelwano oluncedisayo kukho i-arc yombane kwaye i-arc iya kwandiswa kwi-arc yokucima umsantsa wokucima kwaye ngeli xesha i-arc yokucima igesi eqhumayo ukuvuthela i-arc ngexesha langoku lokudlula i-zero.
