DC jenareta VS Syncrhonous jenareta

Musiyano wakakosha pakati peDC Jenareta uye jenareta inonzwisisika inogona kunzwisiswa kubva kumazita avo, DC jenareta inopa Direct Current(DC) uye Synchronous Generator inopa Alternating Current (AC).

Chii chinonzi jenareta?

Jenareta chishandiso chemagetsi chinoshandura Mechanical Energy kuita Magetsi Emagetsi.

Chii chinonzi musimboti we jenareta ?

Iyo EMF inonyengerwa mune conductor inocheka kuburikidza nemagineti flux.Mutemo waFaraday wekupinza.

Maererano nemusimboti uyu, kugadzira magetsi kunoda:

A magnetic field.

Kondakita akaiswa mukati memunda.

Mechanichani yekugadzira nhanho yehukama pakati pezviviri.

Nzira yekubvisa magetsi kubva kune conductor.

A DC jenareta, sekureva kunoita zita rinogadzira, DC magetsi.Muchiitiko ichi munda wakamira.Munda unomonereka pamwe chete nemapango anoroverwa mhepo yemunda uye joko, furemu yekunze yemuchina, iyo mapango anobatanidzwa nayo inonzi stator.Mukati me stator pane armature yakaumbwa yearature core uye armature winding, iyo inonzi rotor.

Kana iyo rotor ichitenderedzwa neimwe nzira yekunze iyo armature coil inocheka kuburikidza nemagnetic field yakagadzirwa ne stator.Magetsi anogadzirwa nekudaro anotorwa ne dint ye slip mhete nemhangura kana kabhoni brashi.Magetsi anogadzirwa haasi DC pakutanga, ichikamu chimwe chete AC.

Nekushandisa commutator iyi bidirectional AC inoshandurwa kuita unidirectional AC.Iyi haina unidirectional asi kwete chete DC.

Zvichienderana nekurongeka kwedunhu remumunda maDC jenareta ndeemhando mbiri:

Kuparadzaniswa kunakidzwa: munda unopihwa simba nekunze DC sosi.

Self Excited: chikamu cheEMF chinogadzirwa chinoshandiswa kupa simba redunhu remunda.Pano residual magnetism inoshandiswa kugadzira magetsi ekutanga.Kune 3 marudzi e-self-excited DC jenareta:

Shunt Jenareta- Munda uri mu shunt ne armature.

Series Jenareta- Munda uri munhevedzano neiyo armature.

Compound Jenareta- Musanganiswa wezvose zvakatevedzana uye shunt michina.

Jenareta inopindirana- inoshanda pamusimboti mumwe chete asi inogadzira 3-chikamu AC.Pane mumwe mutsauko wakakosha, kana DC jenareta munda wakamira, asi kana iri synchronous jenareta munda uri kutenderera uye armature yakamira.Iyo stator imba kune 3-chikamu mhepo.Iwo ma voltages anogadzirwa mune aya ma windings ari 120 madhigirii kubva kune mumwe nemumwe muchikamu.Synchronous jenareta michina yakasimba-yakasimba.

Chakanakira chekumira armature ndechekuti, inobvisa inotsvedza mhete uye mabhurashi kubva pane iyo mamiriro, magetsi anogona kutorwa zvakananga kubva kune armature terminals zvichiita kuti maitiro acho ashande nekudzikisa kurasikirwa kwekusangana.Nharaunda yemunda inonakidzwa nebrashiless exciter circuit yakasungirirwa pa rotor shaft.

Iyo idiki AC jenareta iyo armature yakaiswa pane rotor shaft uye munda wakamira.Munda weiyo exciter iri kumira unopihwa nekunze dc.Nekutenderera kwe rotor, 3-phase ac inogadzirwa iyo inoshandurwa kuita dc uchishandisa 3-phase rectifier zvakare yakaiswa pa rotor.Iyi DC inoshandiswa kupa simba munda mukuru.

Rotor inotenderedzwa uchishandisa prime mover inogona kuva yemhando dzakawanda, semuenzaniso: turbine yemvura, turbine yemvura, turbine yemhepo, injini uye nezvimwe.

For dhiziri jenareta set , ese akawanda ane AC jenareta.Tinovimba kuti ruzivo rwuri pamusoro rwunobatsira kwauri kuti udzidze nezve majenareta.
