Ijenereyitha sisixhobo esiguqula amandla omatshini ajikelezayo abe ngumsinga wombane. Iijeneretha ze-asynchronous zisebenzisa imigaqo yeemotor zokungenisa ukuguqula amandla e-kinetic ukusuka kwimagnethi ezihambayo kunye neekhoyili, ezidityaniswe ngocingo olunamavili lobhedu kumbindi wentsimbi, zibe ngumbane wombane kwaye emva koko zitshintshe umsinga kwizixhobo zasekhaya okanye iinjongo zoshishino.
Inkqubo yokuvelisa i-AC ye-asynchronous ngokuqhelekileyo ibandakanya amacandelo amathathu amakhulu: i-rotor (inxalenye ejikelezayo), i-stator (isethi emileyo yabaqhubi) kunye neesekethe zemagneti ezifakwe macala onke ukuze zime ngokuhambelana ne-axis yayo yokujikeleza; imimandla ye-electromagnetic edalwe kuloo mimandla ibangela imisinga kwiingcingo ezijikajikayo xa idlula kwezi ndawo ngenxa yotshintsho olunyanzelise ukuba luhambe-directionality.

Isebenza njani ijenereyitha yoqhelaniso?
Amandla e-generator induction aveliswa kumahluko kwizantya zokujikeleza phakathi kwe-rotor kunye ne-stator. Kumsebenzi wesiqhelo, amasimi ajikelezayo emoto ajikeleza ngesantya esiphezulu kuneekhoyili ezihambelanayo ukwenza umbane. Oku kuvelisa i-magnetic fluxes kunye ne-polarities echaseneyo ethi idale imisinga evelisa ukujikeleza okungaphezulu kumacala omabini - elinye icala livelisa umsinga wombane ngelixa elinye linyusa i-torque yokuqala de ifikelele kwizantya ezihambelanayo apho kuya kubakho amandla awoneleyo okuvelisa imveliso epheleleyo ngaphandle kwegalelo. amandla afunekayo!
Uthini umahluko phakathi kwe-synchronous kunye ne-induction generator?
Iijeneretha ze-synchronous zivelisa i-voltage ehambelana nesantya se-rotor. Iijenereyitha zokungenisa, kwelinye icala, zithatha amandla asebenzayo kwigridi yombane yengingqi yakho ukuze zivuyise amasimi azo kwaye zivelise umbane- ke zinovakalelo kakhulu kutshintsho kwigalelo lefrikhwensi kunokuba zinjalo iijenereyitha ezihambelanayo!
Ziziphi izinto ezingeloncedo kwijenereyitha yokwenziwa?
Iijenereyitha zokungeniswa aziqhelekanga ukusetyenziswa kwiinkqubo zamandla kuba zinezinto ezimbalwa ezingeloncedo. Umzekelo, ayifanelekanga ukuba isebenze ngokwahlukeneyo, yodwa; i-generator idla kunokuba ibonelele nge-magnetizing i-KVAR eshiya ngakumbi ukuba yenziwe yi-synchronous generator kunye ne-capacitors; kwaye ekugqibeleni ukufakwa akunakho ukufaka isandla ekugcineni amanqanaba ombane wenkqubo njengezinye iintlobo zeeyunithi zokuvelisa.
Ngaba ijenereyitha yokuqalisa ukuziqalela?
Iijenereyitha zokungeniswa aziqalisi. Banokwenza kuphela ujikelezo lwabo xa besebenza njengejenereyitha. Xa umatshini usebenza kule ndima, uthatha amandla asebenzayo kumgca wakho we-AC kwaye uvelise amandla asebenzayo abuyele kucingo oluphilayo!

Kutheni le nto umatshini wokwazisa ungafane usetyenziswe njengejenereyitha?
Umatshini wokungeniswa awusetyenziswanga njengejenereyitha ngenxa yokufumaneka kweejeneretha ze-synchronous kunye nee-alternators. Ii-SG ziyakwazi ukuvelisa zombini amandla asebenzayo kunye namandla asebenzayo, ngelixa ii-IGs zivelisa kuphela amandla asebenzayo ngelixa zisebenzisa amandla asebenzayo. Oku kuthetha ukuba i-IG kuya kufuneka ukuba yenziwe ibenkulu kunokufuneka kwimveliso yayo ukuze ikwazi ukumelana neemfuno zayo zegalelo ezinokubiza kakhulu ngenxa yamanqanaba asezantsi okusebenza kwayo.
Kuphantsi kweyiphi imeko apho umatshini wokungenisa izinto unokusetyenzwa njengejenereyitha?
Iinjini zokungeniswa zinokuvelisa amandla njengejenereyitha xa isantya se-prime mover sikwizantya ezihambelanayo kodwa hayi ngaphezulu kwayo. Umgaqo-siseko osisiseko wokuvelisa umbane ngemoto yokungeniswa ine-frequency resonant, kwaye ukuze uvelise loo maza omoya udinga okungaphezulu nje komatshini wokungeniswa ngokwakho. Xa usebenzisa le jenereyitha ngokufanelekileyo, ukudibanisa kufuneka kwenziwe phakathi kwamacandelo amabini aya kuthi omabini abe nendawo yawo ejikelezayo ye-electromagnetic edityaniswayo ukuze ahambelane njengeyunithi enye.
Kuphantsi kwayiphi imeko apho i-Induction Motor isebenza njengeJenereyitha? Njengoko bekutshiwo ngaphambili, ukuba akukho mthwalo wangaphandle udityanisiweyo, ngoku uqukuqela ngokukhululekileyo kuyo nayiphi na isekethe ene-self-inductance impedance-nto leyo ethetha ukuba amandla ombane anqumlayo aqala ukwakha de i-terminal voltages igqithe kabini umbane welayini ukusuka kumthombo.
Kutheni le nto i-motor induction ingenakubaleka ngesantya esihambelanayo?
Akunakwenzeka ukuba i-motor induction isebenze ngesantya esihambelanayo kuba umthwalo kuyo kufuneka uhlale usetyenziswa. Nangona kungekho mithwalo, bekuya kuhlala kukho ilahleko yobhedu kunye nokukhuhlana komoya ngenxa yokuqhuba umatshini onamandla ngolo hlobo. Ngoku engqondweni, isiliphu senjini asinakuze sifike ku-zero
