Ijenereyitha engathathi hlangothi kwikhabhinethi yokumelana nesiseko

Ijenereyitha inqaku elingathathi hlangothi lokumelana nekhabhathi eFakelweyo Umfanekiso

Inkcazelo emfutshane:

Ikhabhinethi engathathi hlangothi yokumelana ne-Hongyan generator ifakwe phakathi kwendawo engathathi hlangothi yejeneretha kunye nomhlaba.Ngethuba lokusebenza kwe-generator, i-single-phase-grounding iyona nto ixhaphake kakhulu, kwaye indawo ephosakeleyo iya kwandisa ngakumbi xa i-arcing isekelwe.Umonakalo wokugquma kwe-stator okanye ukutshisa okuphakathi kwentsimbi kunye nokutshisa.Ngamazwe ngamazwe, kwiimpazamo zomhlaba wesigaba esisodwa kwiinkqubo zejeneretha, ukuchasana okuphezulu kwesiseko kwindawo engathathi hlangothi yeejeneretha kusetyenziswa ngokubanzi ukukhawulela umhlaba okhoyo kunye nokuthintela iingozi ezahlukeneyo zokugqithisa.Inqaku elingathathi hlangothi linokuthi lisekelwe kwi-resistor ukukhawulela impazamo yangoku kwixabiso elifanelekileyo, ukuphucula uvakalelo lokukhusela i-relay kunye nesenzo sokukhubeka;ngelo xesha, kuphela ukutshisa okuncinci kwendawo kunokuthi kwenzeke kwindawo yempazamo, kwaye ukugqithisa okwethutyana kunqunyelwe kumbane oqhelekileyo womgca.Amaxesha angama-2.6 we-voltage ye-neutral point, ethintela ukutshiswa kwakhona kwe-arc;ikhusela i-arc gap overvoltage ekonakalisa izixhobo eziphambili;kwangaxeshanye, inokuthintela ngempumelelo i-ferromagnetic resonance overvoltage, ngaloo ndlela iqinisekisa ukusebenza ngokukhuselekileyo kwejenereyitha.

Ingcaciso yeMveliso

Zininzi iindlela zolwakhiwo lwekhabhathi engathathi hlangothi yejenereyitha, ezona zixhaphakileyo zezi zimbini zilandelayo:
(1) Inkqubo yesakhiwo apho indawo engathathi hlangothi yejeneretha isekelwe ngokuthe ngqo kwikhabhinethi yokumelana.
(2) Iskimu sesakhiwo apho indawo engathathi hlangothi yejeneretha idibaniswe ne-single-phase-grounding transformer kunye ne-resistor.
