Kungani Ijeneretha Isetha Khiqiza I-Shaft Yamanje

Ngaphansi kwezimo ezijwayelekile, ukumelana nokwahlukanisa kwengxenye ejikelezayo yejeneretha esethelwe phansi kuyadingeka ukuthi kube kukhulu kuno-0.5m Ω.Uma iziphetho zombili ze-shaft eyinhloko zisekelwe ngesikhathi esifanayo, i-shaft current ingase yenziwe.I-shaft current idala umonakalo omkhulu kusethi yejeneretha enomjikelezo omude wokusebenza.Uma ingatholakali isikhathi eside, izodala umonakalo omkhulu ezingxenyeni zemishini yesethi ye-generator.Kungani i- isethi yejeneretha ukukhiqiza shaft current?

Izizathu zimi kanje:

Lapho isethi ye-motor iyi-rotor ye-motor, isizathu sibangelwa ngokuyinhloko ukusatshalaliswa kwe-asymmetric yemigqa yamagnetic yamandla kanye nomphumela wamagnetization we-shaft ejikelezayo.Ukusatshalaliswa kwe-asymmetric yemigqa yamagnetic yamandla ngokuvamile kubangelwa i-asymmetry yegebe le-lamination.

Kukhona futhi into yokuthi i-shaft current ikhiqizwa ngenxa yokusetshenziswa kwamandla angaphandle.Isizathu siwukuthi insimu yamagnetic ejikelezayo yeyunithi yemoto yeselula isika umqhubi noma i-rotor engalingani, okuholela kumagnetization we-shaft ejikelezayo.Ukungqubuzana, ukuhlanganisa, ukungqubuzana kanye nemishini yamanje ye-eddy ingase ibangele uzibuthe wemishini futhi isungule indawo kazibuthe.

Lapho inkambu kazibuthe ezungezayo isika umqhubi, lezi zingxenye zizoheha amandla athile.Lapho amandla ekhuphuka ngokwanele ukuze aphule ifilimu kawoyela, kuzokwakhiwa umjikelezo wamanje.Le loop yamanje ingase idlule kuyo yonke i-rotor, noma ingase yakhe kuphela i-current short-circuit yasendaweni ku-bearing noma indandatho entantayo.Le misinga yona ikhiqiza izizibuthe ezintsha ezidonsa izinsimbi noma ezinye izingxenye.Ngakho-ke, lokhu kuguqulwa okuhlangene kwe-magnetoelectricity kuzokwakha insimu enamandla kazibuthe kanye nomthamo ophezulu kusethi ye-generator.I-voltage ebangela i-shaft current yesethi ye-generator ingaphezu kuka-20V, kanti i-voltage eyonakele iphakathi kuka-30 ~ 100V.Ngakho-ke, ukuqinisekisa ukusebenza okuvamile kwesethi ye-generator kunganciphisa ngempumelelo i-voltage yesethi ye-generator.Uma i-voltage isingaphansi kwe-1V, i-shaft current ngeke ivezwe.

Uma sisebenzisa isethi yejeneretha, kufanele sihlale sinake ukuthi i-shaft current iyakhiqizwa yini.Uma ikhiqizwa, kufanele sihlaziye ngesikhathi futhi sithole izimbangela, ukuze sigweme isizukulwane se-shaft current.

Kuthiwani uma i-jeneretha shaft current ikhuphuka?

Izinyathelo zokuphepha ezilandelayo zivame ukuthathwa:

(1) Ngesikhathi sokuklama nokufakwa, amaphedi okuvikela ngokuvamile afakwa phakathi kwesisekelo sokuthwala kanye nesisekelo ekugcineni kwe-excitation yejeneretha, futhi izinyathelo zokufakelwa zithathwa kuwo wonke amapayipi kawoyela, izikulufu nezikulufu.

(2) Ukuze uvimbele i-voltage ye-shaft ebangelwa iphuzu elilodwa lokumisa isifunda esifushane sokujika kwe-rotor, faka idivayisi yokuvikela phansi enamaphuzu amabili wesekethe evusa amadlingozi.

(3) Ukuze unqamule i-shaft current, i-exciter side ihlanganisa i-generator bear, uphawu lukawoyela lwe-generator, indawo yokufaka amanzi kanye ne-outlet support kanye ne-inlet yamanzi kanye ne-flange yepayipi yokuphuma. generator amanzi selehlile i-rotor, futhi i-insulating pad ifakwe phakathi kwe-exciter ne-axiliary exciter bear kanye ne-base plate yesisekelo.Ama-fasteners we-bearing pedestal kanye nepayipi likawoyela elixhunywe ku-bearing pedestal nazo zizofakwa i-insulated kusukela ekuthwaleni, futhi izinyathelo zokufakelwa kwezingqimba ezimbili zingamukelwa.

(4) Gwema i-asymmetry yesekethe kazibuthe ekwakhiweni kwemoto.

(5) I-axial magnetic flux izogwenywa ngesikhathi sokuklama, ukwakhiwa kanye nokusebenza kwenjini.

(6) Gxilisa i-bearing pedestal ukusuka phansi.

(7) Faka ibhulashi lesisekelo kushaft.

(8) Yamukela isisekelo esine-non-magnetic bearing noma ikhoyili eyengeziwe.

(9) Engeza i-bypass capacitor phansi ekugcineni kwe-arature motor ye-DC motor.
