Ufakelo lweFuse yohlobo lokuwisa

I-Drop out fuse yilayini yesebe yemigca yokusasazwa ye-10 kV kwaye i-distribution transformer yeyona isetyenziswa kakhulu njengeswitshi yokukhusela i-short-circuit. Isebenza ngoqoqosho, kulula ukuyisebenzisa, ukuze ivumelane nokusingqongileyo kwangaphandle kunye neempawu ezinamandla, isetyenziswa kakhulu kwimigca yokusasazwa ye-10kV kunye necala eliphambili le-distribution transformer njengokhuseleko kunye nezixhobo, ukusebenza kunye nayo. Ifakwe kumgca wesebe lomgca wokusasazwa we-10kV, inciphisa ukucima kombane, kuba inendawo yokuqhawula ecacileyo, inomsebenzi wokwahlula iswitshi, idala indawo yokusebenza ekhuselekileyo kwicandelo lokugcinwa komgca kunye nezixhobo, yandisa ingqiqo yokhuseleko lwabasebenzi bolondolozo. Ifakwe kwi-distribution transformer, ingasetyenziswa njengokhuseleko oluphambili lwe-distribution transformers, ngoko ke, kwimigca yokusasazwa ye-10kV kunye ne-distribution transformers ziye zathandwa.

Umgaqo wayo osebenzayo ngulo: ityhubhu yefuse kuzo zombini iziphelo zoqhagamshelwano oluhambayo kwi-fasten fuse (melt), i-moving contact push "duckbill" bulge, i-phosphorus, ipleyiti yobhedu, njl.njl. yenziwe ngoqhagamshelwano olungashukumiyo phezulu koqhagamshelwano oluhambayo, ngoko ke ityhubhu yefuse ibambeke ngokuqinileyo kwi-"duckbill". Xa umsinga wesekethe emfutshane ngefuse uphumile, i-arcing, ityhubhu yefuse ilinen yefayibha evulcanized phantsi kwempembelelo ye-arc ivelisa inani elikhulu legesi ngenxa yokuba isiphelo esiphezulu sombhobho wefuse sivaliwe, igesi isiya esiphelweni esisezantsi se-spray, ikhupha i-arc. Ngenxa ye-fuse, ityhubhu yefuse ehambayo i-fyuse yoqhagamshelwano ilahlekile, ityhubhu yefuse i-static contact spring piece of self gravity, kwaye phantsi kwayo, ityhubhu yefuse iwela ngokukhawuleza, isekethe iqhawukile, isuswe icandelo lempazamo yomgca okanye ukusilela kwezixhobo.
