Okokuqala, kufuneka sinciphise ubungakanani bengxoxo ukuze sikuphephe ukuyenza ichukumiseke. I-genetor ekuxoxwe apha ibhekisa kwi-generator ye-Ac eqaqambileyo, i-AC-yenqanaba lesithathu le-AC le-AC ye-AC
Olu hlobo lomjelo luquka ubuncinci beenxalenye ezintathu eziphambili, eziya kuthi zichazwe kule ngxoxo ilandelayo:
Umvelisi ophambili, owahlulwe waba yeyona nto iphambili kunye nentloko ephambili; I-rotor ephambili ibonelela ngentsimi yemagneti, kwaye i-stator ephambili ivelisa umbane ukubonelela umthwalo; Uchulumancilini, wahlulahlulwe waba ngumculi kunye nengwevu; Itekisi yogcino ibonelela ngentsimi yemagnethi, umqolo lowo uvelisa umbane, kwaye emva kolungiso ngumnxibelelanisi ojikelezayo, ibonelela ngamandla kwi-rotor ephambili; Umlawuli wevolthi esenzekelayo (AVR) ufumana i-voltage yemveliso yemveliso ephambili, ilawula okwangoku i-Conser Callit, kwaye iphumelele injongo yokuzinzisa i-voltage yemveliso.
Inkcazo yomsebenzi wokuzinza kwe-Avr Vibiage
Injongo yokusebenzela ye-AVR kukugcina i-vogenerator yemveliso yemveliso, ehlala yaziwa ngokuba "yi-voltage stabilizer".
Ukusebenza kwayo kukwandisa i-stator okwangoku xa uvolografi wemveliso iphantsi kunexabiso lemigaqo, efana ne-voltarator ephambili yexabiso; Ngokuchasene noko, nciphisa umnyhadala okwangoku kwaye uvumele i-voltage ukuba inciphe; Ukuba umbono wemveliso womvelisi ulingana nexabiso leseti, i-AVR igcina imveliso ekhoyo ngaphandle kohlengahlengiso.
Ngaphaya koko, ngokwenqanaba lesigaba senqanaba phakathi kwangoku kunye ne-voltage, imithwalo ye-AC inokuhlelwa ngokwamanqanaba amathathu:
Umthwalo onyangekayo, apho okwangoku kwiSigaba kunye nevoli esetyenzisiweyo kuyo; Umthwalo ongaphezulu, inqanaba leleags yangoku emva kwevolthi; Umthwalo ongacacanga, inqanaba langoku liphambi kwe-voltage. Thelekisa iimpawu ezintathu zomthwalo usinceda ukuba siqonde ngcono imithwalo.
Ngomthwalo ongazixhasiyo, umthwalo omkhulu, okhulu ngakumbi onyanisekileyo ofunwayo kwi-rotor ephambili (ukwenzela ukuzinzisa ivolomu yemveliso yomvelisi).
Kwingxoxo elandelayo, siya kusebenzisa umnxibelelanisi wangoku ofunekayo kwimithwalo exhaphakileyo njengomgangatho wesalathiso, okuthetha ukuba ezinkulu zibhekiswa kuzo zibe zikhulu; Siyibiza ngokuba sincinci kunaye.
Xa umthwalo we-generator ukungasebenzi, eyona rotor iphambili iya kufuna ukuba kubekho umbulelo omkhulu ngolungelelwano ukuba alondoloze i-voltage evakalayo.
Umthwalo ongacacanga
Xa umnikiwe jetarator equlethe umthwalo ongacacanga, uchulumanco olufunekayo nge-rotor ophambili luncinci, okuthetha ukuba umnyhadala lowo mfutshane kufuneka ancitshiswe ukuze azinzisa i-voltator yemveliso.
Kutheni le nto yenzeke?
Sisenokukhumbula ukuba okwangoku umthwalo weCawa uqhubeka i-voltage, kwaye ezi ntlobo ziphambili (eziqukuqela i-stator ephambili) ziya kuvuswa kwi-rotor ephambili, eyakhiwe ngokugqibeleleyo kunye ne I-Magnetic Fielfic ye-rotor ephambili. Ke okwangoku kwi-bocreer kufuneka incitshiswe ukuze igcinwe i-voltage efanelekileyo yomvelisi.
Okukhulu komthwalo weCawative, incinci yokuphuma komnxibelelanisi; Xa umthwalo weCawational unyusa ukuya kwinqanaba elithile, iziphumo zomnxibelelanisi kufuneka zincitshiswe kwi-zero. Iziphumo zomnxibelelanisi ngu-zero, ongumda womvelisi; Okwangoku, i-voltage yemveliso yemveliso ayiyi kuba nokuzinza, kwaye olu hlobo loncedo lwamandla alusebenzi. Lo mqobo ukwabizwa ngokuba 'phantsi komda wobunqobotsheli'.
Umvelisi unokusamkela kuphela umthwalo olinganiselweyo; .
Ukuba iprojekthi ikhathazwa yimithwalo yamandla, kunokwenzeka ukuba ukhethe ukusebenzisa imithombo yamandla kunye namandla amancinci nge-kilowatt nge-kilowatt, okanye isebenzise imbuyekezo yembuyekezo. Ungavumeli ukuba ubeke umvelisi abeke usebenze kufutshane ne "phantsi komda wobugcisa".
