MENENE CANJIN SAUKI WUTA?YAYA AKE AIKI?

Ana buƙatar masu canza canjin wuta a sauya kayan wuta.To mene ne masu sauya taransfoma?Menene ka'idodin aiki da ayyuka na sauya tafsiri?Mu fahimce su.

 

·Gabatarwa

Canjin wutan lantarki yana nufin mai canza wuta da ake amfani da shi a cikin wutar lantarki.Yana aiki a cikin yanayin bugun jini tare da mitar goma zuwa dubun kilohertz ko ma ɗaruruwan kilohertz.Ƙarfe gaba ɗaya an yi shi da kayan ferrite.

           

·Ƙa'idar aiki na canza canjin

Transformer na'urar lantarki ce da aka yi ta amfani da ƙa'idar shigar da wutar lantarki.Lokacin da aka haɗa babban coil na na'ura mai canzawa zuwa tushen wutar lantarki na AC, core baƙin ƙarfe yana samar da canjin maganadisu.Ana sarrafa wutar lantarki ta hanyar kewayawa, kuma bututu mai sauyawa yana canzawa cikin sauri.

Ana ba da jujjuya halin yanzu kai tsaye zuwa babban mitar alternating current zuwa na'ura mai canzawa don canzawa, ta haka ne ke haifar da saiti ɗaya ko fiye na ƙarfin lantarki.Tunda ingancin babban mitar AC a cikin da'irar taswira ya fi girma fiye da 50Hz, ana iya yin duk na'urorin canza canji kaɗan kaɗan, ta haka rage farashin.

 

·Tya taka rawar canza tasfoma

Babban ayyuka na sauya tafsirin su ne watsa wutar lantarki, jujjuyawar wutar lantarki da kuma rufi.

Babban fa'idodinsa shine ƙananan girman, babban inganci, da arha mikewa.A matsayin babban ɓangaren maganadisu mai laushi mai laushi, ana amfani da masu canza canjin wutar lantarki sosai wajen sauya fasahar samar da wutar lantarki da fasahar lantarki, kuma ana amfani da su a cikin da'irori masu yawa kamar sauya kayan wuta.

 

Dangane da ikon watsawar na'ura mai canzawa, ana iya raba masu taswirar wutar lantarki zuwa maki da yawa: 10kVA babban iko ne, 10kVA ~ 0.5kVA matsakaici ne, 0.5kVA ~ 25VA ƙaramin ƙarfi ne, kuma ƙasa 25VA shine ƙaramin ƙarfi.Ikon watsawa daban-daban, ƙirar wutar lantarki shima ya bambanta.ferrite core da Magnetic saturation coefficient na wutar lantarki ba su da kyau kamar na silin karfe core core, yana haifar da ƙarancin kuzari a kowane Hertz na canja wurin wutar AC.Amma yana aiki a cikin da'ira mai girma, kuma mitar musayar makamashi a kowane tazara na lokaci yana da girma sosai (sau 1000 na na'ura mai ɗaukar nauyi).Idan aka haɗu, ingancinsa na iya kaiwa sau da yawa fiye da na masu canji mara ƙarfi.

 

·Wani aikin na'urar ta sauya sheka shi ne cewa yana da jujjuyawar martani

Gudun ra'ayoyin yana ba da siginar amsawa mai kyau ga PWM IC, yana haifar da shi don haifar da maɗaukakiyar oscillation tare da iska na biyu, ta yadda DC da ke shiga farkon iska na na'ura yana da babban ɓangaren AC, da kuma AC mai girma. An keɓe bangaren da na’urar wutan lantarki (transformer core), wanda ke samar da AC mai tsafta mai tsafta ta biyu, wanda aka gyara da tacewa don samar da kayan lantarki.Juyawar martani na iya daidaita ƙarfin fitarwa zuwa madaidaicin ƙima.A taƙaice, na'ura mai canzawa tana taka rawar watsa wutar lantarki, jujjuyawar wutar lantarki da kuma rufewa.
