Kodi Ma Fuse Apamwamba Amagetsi Ndi Chiyani?

Choyamba, titha kuyang'ana mawonekedwe a ma fuse apamwamba kwambiri.

Monga tikudziwira, ntchito yama fuse apamwamba kwambirindi kuteteza dera.Ndiko kuti, pamene panopa mu dera ladutsa mtengo wotchulidwa, kusungunula mkati mwa fuse kumatulutsa mtundu wa kutentha kuswa dera.Chifukwa chake, pazida zophatikizira ma voltage apamwamba, ziyenera kukhala ndi malo otsika osungunuka, osavuta kuzimitsa mawonekedwe a arc.Nthawi zambiri kuphatikiza mkuwa, siliva, nthaka, lead, lead malata aloyi ndi zinthu zina.Chifukwa chakuti malo osungunuka a zipangizozi ndi osiyana, zipangizo zosiyanasiyana zimafunikira pa mafunde osiyanasiyana.Kutentha kwawo kumagwirizana ndi 1080 ℃, 960 ℃, 420 ℃, 327 ℃ ndi 200 ℃ motsatana.

Malangizo ogwiritsira ntchito zinthu zosiyanasiyanazi ndi awa:
1. Malo osungunuka a zinki, lead, lead-tin alloy ndi zitsulo zina ndizochepa, koma resistivity ndi yaikulu.Choncho, ntchito fuseji mtanda gawo m'dera lalikulu, nthunzi zitsulo kwaiye pamene fusing si kothandiza kuzimitsa arc.Amagwiritsidwa ntchito kwambiri m'dera lomwe lili pansipa 1kV.
2. Mkuwa ndi siliva zimakhala ndi malo osungunuka kwambiri, koma resistivity yaying'ono komanso magetsi abwino ndi matenthedwe.Choncho, ntchito fuseji mtanda gawo m'dera laling'ono, nthunzi zitsulo kwaiye pamene fusing ndi zochepa, zosavuta kuzimitsa arc.Ikhoza kugwiritsidwa ntchito mu high voltage, high current circuit.Komabe, ngati panopa ndi yaikulu kwambiri, kutentha kwa nthawi yaitali kumakhala kokwera kwambiri, kosavuta kuwononga zigawo zina mu fuseji.Pofuna kusungunula fusesi mofulumira, iyenera kudutsa mumtsinje waukulu, mwinamwake idzatalikitsa nthawi ya fusesi, yomwe si yabwino kwa zipangizo zotetezera.Kuti athetse vutoli, tini kapena pellet yotsogolera nthawi zambiri imawotchedwa pa mkuwa kapena siliva kusungunula kuti kuchepetsa kutentha kusungunuka ndi kupititsa patsogolo chitetezo cha sungunuka.
