Gabatarwa ga ka'idar babban mai canzawa

1920

Kamar yadda sunan ke nunawa, babban mai juyawa shine kayan lantarki mai ƙarfi wanda ke canza ƙarfin lantarki.Na'ura ce da ke amfani da dokar Faraday na shigar da wutar lantarki don canza wutar lantarki ta AC, galibi ta ƙunshi na'urar farko, ferrite.core, secondary coil, da dai sauransu. Yana iya gane madaidaicin tuba na shigarwa da fitarwa na yanzu, ƙarfin lantarki da impedance, da kuma keɓewar jiki na matakin farko.Dangane da nau'in wutar lantarki na farko daban-daban, ana iya raba shi zuwa na'ura mai ɗaukar nauyi mai ƙarfi, mataki-up high-frequency transformer da keɓance babban mai canzawa.

Yawan wutar lantarki da ake amfani da shi a rayuwarmu ta yau da kullun shine 50Hz, wanda ake kira low-frequency alternating current.Idan na'ura mai karfin gaske yana aiki a wannan mitar, mukan kira shi da babban tafsirin mai karfin mitar mai-girma, wanda kuma ake kira da wutar lantarki mai girma.Babban mai juyawa yana da babban girma da ƙarancin inganci.An jibge tushen baƙin ƙarfe tare da zanen ƙarfe na siliki wanda aka keɓe tare, kuma nada na farko yana rauni da waya mai ƙyalli.Ƙarfin wutar lantarki na farko ya yi daidai da jujjuyawar su.

Bugu da kari, wasu manyan na'urorin na'urar wuta suna aiki a cikin daruruwan daruruwan kilohertz saituna, kuma wannan babban taswirar ta zama babban mai canzawa.Maɗaukakin tasfotoci gabaɗaya suna amfani da muryoyin maganadisu maimakon baƙin ƙarfe.Babban mai canzawa yana da ƙaramin ƙara, ƴan juyi na coil na farko da babban inganci.

Mitar aiki na babban taswira yawanci dubun zuwa ɗaruruwan kilohertz ne.Babban mai canzawa yana ɗaukar magnetic core, kuma babban ɓangaren magnetic core shine manganese zinc ferrite.Wannan abu yana da ƙarancin eddy halin yanzu, ƙarancin hasara da babban inganci a babban mitoci.Matsakaicin mitar aiki na babban mitar mai canzawa shine 50Hz.Babban mitar wutar lantarki wani nau'i ne na kayan maganadisu mai taushin ƙarfe.Bakin karfe siliki na bakin karfe na iya rage yawan asarar da aka yi a halin yanzu, amma asarar har yanzu ta fi na babban madanni mai canzawa.

Na'urar mai saurin mitar mai da wutar lantarki iri ɗaya ta fi ƙanƙanta fiye da na'urar wutar lantarki mai ƙaranci, kuma ƙarfin dumamasa kaɗan ne.Don haka a halin yanzu, yawancin adaftar wutar lantarki na masu amfani da kayan lantarki da samfuran cibiyar sadarwa suna canza kayan wuta, kuma babban mai canzawa na cikin gida shine mafi mahimmancin abin da ke canza wutar lantarki.Babban ka'idar ita ce canza shigar da musanya mai canzawa zuwa DC, sa'an nan kuma canza shi zuwa babban mitar ta hanyar triode ko FET.Ta hanyar canza canjin mai yawan mitoci, ana sake gyara kayan fitarwa, kuma ana ƙara wasu sassan sarrafawa don daidaita ƙarfin wutar lantarki na DC.

A takaice dai, kamanceceniya tsakanin manyan na'urori masu yawa da na'urori masu ƙarfi sun dogara ne akan ka'idar shigar da wutar lantarki.Bambance-bambancen shi ne cewa ƙananan mitar da manyan na'urori masu canzawa na ƙarfe ne da aka yi da zanen ƙarfe na siliki, kuma manyan injinan wutar lantarki gabaɗaya ne na manganese zinc ferrite da sauran kayan.
