Ijenereyitha engathathi hlangothi kwikhabhinethi yokumelana nesiseko
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 i-overvoltage edlulayo inqunyelwe 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.

Ikhabhinethi yokumelana neTransformer engathathi hlangothi
Kwigridi yamandla ye-6-35KV AC yenkqubo yamandla yelizwe lam, kukho iindawo ezingathathi hlangothi, ezisekelwe kwiikhoyili zokucinezelwa kwe-arc, ukuxhathisa okuphezulu okusekelwe phantsi, kunye nokumelana okuncinci okusekelwe phantsi.Kwinkqubo yamandla (ingakumbi inkqubo yonikezelo lwamandla othungelwano lwasezidolophini kunye neentambo njengemigca yothumelo ephambili), i-ground capacitive current inkulu, enokwenza ukuba kwenzeke "intermittent" arc overvoltage yomhlaba ineemeko ezithile "ezibalulekileyo", ezikhokelela kwi-arcing. Ukusetyenziswa kwendlela yokusekela indawo engathathi hlangothi yokuvelisa i-grounding overvoltage yenza umjelo wokukhupha amandla (intlawulo) kwi-grid-to-ground capacitance, kwaye ifake i-resissive current kwi-fault point, yenza ukuba i-grounding fault current ithathele ingqalelo. indalo yokumelana-i-capacitance, ukunciphisa kunye Umehluko we-angle yesigaba se-voltage kunciphisa izinga lokutsha kwakhona emva kokuba okwangoku kwindawo yecala liwela i-zero kwaye liphule imeko "ebalulekileyo" ye-arc overvoltage, ukwenzela ukuba i-overvoltage iyancipha ngaphakathi kwe-2.6 amaxesha ombane wesigaba, kwaye kwangaxeshanye uqinisekisa ukhuseleko lomhlaba olunovakalelo oluphezulu Isixhobo simisela ngokuchanekileyo kwaye sinqumle iziphene eziziiprayimari nezesibini ze-feeder, ngaloo ndlela zikhusela ngokufanelekileyo ukusebenza kwesiqhelo kwenkqubo.
