DC Generator VS Syncrhonous Generator

Bambanci na asali tsakanin DC Generator da syncrhonous janareta ana iya fahimtar su daga sunayensu, DC janareta yana ba da Direct Current (DC) da Synchronous Generator yana ba da Alternating Current(AC).

Menene janareta?

Janareta na'urar lantarki ce da ke juyar da Makamashi Makamashi zuwa Makamashin Lantarki.

Menene ka'idar janareta ?

Ana haifar da EMF a cikin mai yanke hukunci ta hanyar juzu'in maganadisu.Dokar shigar da Faraday.

Bisa wannan ka'ida, don samar da wutar lantarki ana buƙatar:

Filin maganadisu.

Direbobin da aka sanya a cikin filin.

Hanya don ƙirƙirar saurin dangi tsakanin su biyun.

Hanyar fitar da wutar lantarki daga madugu.

A DC janareta, kamar yadda sunan ya nuna yana haifar, DC wutar lantarki.A wannan yanayin filin yana tsaye.Filin jujjuyawar tare da sandunan da filin ya yi rauni da kuma karkiya, firam ɗin waje na injin, wanda sandunan ke haɗin gwiwa da shi ana kiransa stator.A cikin stator akwai armature kafa na armature core da armature winding, wanda ake kira rotor.

Lokacin da rotor ke jujjuya ta wasu hanyoyi na waje, igiyar armature ta yanke ta cikin filin maganadisu da stator ya ƙirƙira.Ana fitar da wutar lantarki ta haka ne ta hanyar ɗimbin zoben zamewa da jan ƙarfe ko goga na carbon.Wutar lantarkin da aka samar ba DC da farko ba, lokaci guda ne AC.

Ta amfani da mai kewayawa wannan AC na biyu yana jujjuya zuwa AC unidirectional.Wannan unidirectional ne amma ba kawai DC ba.

Ya danganta da yadda aka tsara da'irar filin wutar lantarkin DC janareto iri biyu ne:

Na dabam mai farin ciki: filin yana samun kuzari daga tushen DC na waje.

Jin daɗin Kai: ana amfani da wani yanki na EMF da aka samar don ƙarfafa da'irar filin.Anan ana amfani da ragowar maganadisu don samar da wutar lantarki ta farko.Akwai nau'ikan janareta na DC guda uku masu jin daɗin kai:

Shunt Generator- Filin yana cikin shunt tare da armature.

Series Generator- Filin yana cikin jerin tare da armature.

Compound Generator- Yana da haɗe-haɗe na duka jerin da tsarin shunt.

Janareta mai aiki tare- yana aiki akan ƙa'ida ɗaya amma yana haifar da AC mai kashi 3.Akwai wani muhimmin bambanci, idan akwai janareta na DC filin yana tsaye, amma idan filin janareta na aiki tare yana jujjuyawa kuma armature yana tsaye.Stator yana gida zuwa iska mai hawa 3.Wutar lantarki da aka samar a cikin waɗannan iskoki suna da digiri 120 ban da juna a lokaci.Na'urori masu haɗaka da juna manyan injuna ne masu ƙarfi.

Amfanin armature na tsaye shine, yana kawar da zoben zamewa da gogewa daga yanayin yanayin, ana iya fitar da wutar lantarki kai tsaye daga tashoshi na armature yana sa tsarin ya fi dacewa ta hanyar rage asarar lamba.Da'irar filin tana jin daɗi ta hanyar da'ira mara gogewa wanda aka ɗora akan mashin rotor.

Karamin janareta na AC ne wanda armaturensa ke dora akan rotor shaft kuma filin a tsaye.Ana ba da filin na exciter kasancewar a tsaye tare da dc na waje.Tare da jujjuyawar rotor, 3-phase ac da aka samar wanda aka canza zuwa dc ta amfani da mai gyara lokaci 3 shima an ɗora akan rotor.Ana amfani da wannan DC don ƙarfafa babban filin.

Ana jujjuya na'urar ta amfani da firam mai motsi wanda zai iya zama iri-iri, misali: injin tururi, injin ruwa, injin injin iska, injin da sauransu.

Domin saitin janareta dizal , duk mafi yawan suna sanye da janareta na AC.Muna fatan bayanin da ke sama zai taimaka muku don koyo game da janareta.
