Ijeneretha iyisisetshenziswa esiguqula amandla emishini ajikelezayo abe wamanje kagesi. Amajeneretha angama-asynchronous asebenzisa izimiso zamamotho angeniswayo ukuze aguqule amandla e-kinetic asuka kuzibuthe namakhoyili ahambayo, axhunywe ngamawindi ocingo lwethusi kunkango yensimbi, abe amandla kagesi bese ashintshana ngemishini yasendlini noma ngezinjongo zezimboni.
Isistimu ekhiqizayo ye-AC engavumelaniyo ngokuvamile ihlanganisa izingxenye ezintathu ezinkulu: i-rotor (ingxenye ejikelezayo), i-stator (isethi emile yamakhondatha) eneziyingi kazibuthe ezigxunyekwe eduze kwayo ukuze ime ngokuhlobene ne-eksisi yayo yokuzungezisa; Izinkambu zikagesi ezidalwe kulezo zifunda zibangela imisinga ezintanjeni ezijikajikayo uma zidlula kulezi zindawo ngenxa yoshintsho lwazo olubeke ukunyakaza-isiqondiso.
Kulokhu okuthunyelwe sizomboza:
- Isebenza kanjani ijeneretha yokungeniswa?
- Uyini umehluko phakathi kwejeneretha ye-synchronous kanye ne-induction?
- Yibuphi ububi bejeneretha yokungeniswa?
- Ingabe ijeneretha yokungeniswa iyijeneretha yokuziqala?
- Kungani umshini wokungenisa izinto ungavamile ukusetshenziswa njengejeneretha?
- Kungaphansi kwasiphi isimo lapho umshini wokungeniswa ungasetshenziswa njengejeneretha?

Isebenza kanjani ijeneretha yokungeniswa?
Amandla ejeneretha yokungeniswa akhiqizwa kusukela kumehluko wesivinini sokujikeleza phakathi kwe-rotor yayo ne-stator. Ekusebenzeni okuvamile, amasimu enjini ajikelezayo ajikeleza ngesivinini esikhulu kunamakhoyili azo ahambisanayo ukuze akhe ugesi. Lokhu kukhiqiza ama-fluxes kazibuthe ane-polarities ephikisanayo bese idala imisinga ekhiqiza ukuzungezisa okuningi ezinhlangothini zombili - uhlangothi olulodwa lukhiqiza amandla kagesi kanti olunye lukhuphula i-torque yokuqala ize ifinyelele isivinini esivumelanayo lapho kuzoba namandla anele okukhiqiza okuphumayo okugcwele ngaphandle kwanoma yikuphi okokufaka. amandla adingekayo!
Uyini umehluko phakathi kwejeneretha ye-synchronous kanye ne-induction?
Amajeneretha angama-synchronous akhiqiza i-voltage evumelaniswa nesivinini se-rotor. Amajeneretha okungenisa, ngakolunye uhlangothi, athatha amandla asebenzayo kugridi yangakini kagesi ukuze athokozise izinkambu zawo futhi akhiqize ugesi - ngakho azwela kakhulu ezinguqukweni zefrikhwensi yokufaka kunamajeneretha ahambelanayo!
Yibuphi ububi bejeneretha yokungeniswa?
Amajeneretha okungenisa awavamile ukusetshenziswa ezinhlelweni zamandla ngoba anobubi obumbalwa. Isibonelo, ayifanele ukusebenza ngokwehlukana, okukodwa; i-generator idla kunokuba inikeze i-KVAR eyenza i-magnetizing eshiya okuningi okumele kwenziwe ngamajeneretha nama-capacitor angama-synchronous; futhi ekugcineni ukufakwa akukwazi ukufaka isandla ekugcineni amazinga kagesi wesistimu njengezinye izinhlobo zamayunithi akhiqizayo.
Ingabe ijeneretha yokungeniswa iyijeneretha yokuziqala?
Amajeneretha okungenisa awazona iziqalisi. Bangakwazi ukunika amandla ukuzungezisa kwabo kuphela uma besebenza njengejeneretha. Uma umshini usebenza kule ndima, uthatha amandla asebenzayo emugqeni wakho we-AC futhi ukhiqize amandla asebenzayo abuyele entanjeni ebukhoma!

Kungani umshini wokungenisa izinto ungavamile ukusetshenziswa njengejeneretha?
Umshini wokungeniswa awusetshenziswa njengejeneretha ngenxa yokutholakala kwamajeneretha nama-alternator ahambisanayo. Ama-SG ayakwazi ukukhiqiza kokubili amandla asebenzayo namandla asebenzayo, kuyilapho ama-IG ekhiqiza amandla asebenzayo kuphela kuyilapho esebenzisa amandla asebenzayo. Lokhu kusho ukuthi i-IG izodinga usayizi omkhulu kunalowo odingekayo ukuze ikhiphe ukuze isingathe izidingo zayo zokufaka ezingabiza kakhulu ngenxa yamazinga azo aphansi okusebenza kahle.
Kungaphansi kwasiphi isimo lapho umshini wokungeniswa ungasetshenziswa njengejeneretha?
Ama-induction motors angakhiqiza amandla njengamajeneretha lapho ijubane le-prime mover lisesivinini esivumelanayo kodwa lingekho ngaphezu kwalo. Umgomo oyisisekelo wokukhiqiza ugesi nge-induction motor ine-resonant frequency, futhi ukuze ukhiqize leyo frikhwensi udinga okungaphezu nje komshini wokungeniswa uwedwa. Uma usebenzisa le generator kahle, ukuhlanganisa kufanele kwenziwe phakathi kwezingcezu ezimbili zombili zizovunyelaniswa inkambu yazo kagesi kagesi ukuze zihambisane njengeyunithi eyodwa .
I-Induction Motor isebenza ngaphansi kwasiphi isimo njengeGeneretha? Njengoba kushiwo ngaphambili uma ungekho umthwalo wangaphandle oxhumene, khona-ke okwamanje kugeleza ngokukhululeka kunoma iyiphi isekethe ene-self-inductance impedance-okusho ukuthi i-voltage ngaphesheya iqala ukukhula kuze kube yilapho ama-terminal voltages edlula kabili i-voltage yolayini ukusuka emthonjeni.
Kungani injini yokungeniswa ingakwazi ukusebenza ngesivinini esivumelanayo?
Akwenzeki ukuthi i-induction motor isebenze ngesivinini esivumelanayo ngoba umthwalo okuyo kufanele uhlale usetshenziswa. Ngisho noma ingekho imithwalo, bekuyoba khona ukulahlekelwa yithusi nomoya ngenxa yokusebenzisa umshini onamandla kangaka. Unalokhu engqondweni, isiliphu se-motor asisoze safinyelela kuziro
