Ikhabhinethi ye-Generator point grounding resistance resistance

Ikhabhinethi yokumelana nephuzu elingathathi hlangothi lejeneretha yaseHongyan ifakwe phakathi kwendawo engathathi hlangothi yejeneretha kanye nomhlabathi.Ngesikhathi sokusebenza kwejeneretha, ukubeka phansi kwesigaba esisodwa kuyiphutha elivame kakhulu, futhi iphuzu lephutha lizoqhubeka nokukhula lapho i-arcing isekelwe.Ukulimala kokufakwa kwe-Stator winding noma ukusha nokushiswa kwe-iron core.Emazweni ngamazwe, ngenxa yamaphutha aphansi esigaba esisodwa ezinhlelweni zamajeneretha, ukusekela ukumelana okuphezulu endaweni engathathi hlangothi yamajeneretha kusetshenziswa kabanzi ukuze kukhawulwe amandla angaphansi komhlaba kanye nokuvimbela izingozi ezihlukahlukene zokugcwala kwamanzi.Iphoyinti elingathathi hlangothi lingamiswa ngesiphikisayo ukuze kukhawulwe iphutha lamanje kunani elifanele, kuthuthukiswe ukuzwela kwesivikelo sokudlulisela kanye nokwenza okuthile ekukhubekeni;ngesikhathi esifanayo, ukushiswa okuncane kwendawo kuphela kungase kwenzeke endaweni yephutha, futhi i-overvoltage yesikhashana inqunyelwe ku-voltage yomugqa ovamile.Izikhathi ezingu-2.6 ze-voltage yephoyinti engathathi hlangothi, ekhawulela ukuvutha kabusha kwe-arc;ivimbela i-arc gap overvoltage ekulimazeni imishini eyinhloko;ngesikhathi esifanayo, ingavimbela ngempumelelo i-ferromagnetic resonance overvoltage, ngaleyo ndlela iqinisekise ukusebenza okuphephile kwejeneretha.
