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 kwensimbi.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.

Ikhabhinethi yokumelana nephuzu elingathathi hlangothi le-Transformer
Kugridi yamandla engu-6-35KV AC yohlelo lwamandla ezwe lami, kunamaphuzu angathathi hlangothi angagxiliwe, asekelwe ngamakhoyili okucindezela ama-arc, asekelwe phansi ukumelana kakhulu, kanye nokumelana nokuncane okusekelwe phansi.Ohlelweni lwamandla (ikakhulukazi uhlelo lokuphakelwa kwamandla enethiwekhi yasemadolobheni enezintambo njengezintambo eziyinhloko zokudlulisa), i-ground capacitive current inkulu, engase yenze ukuvela kwe-arc overvoltage yomhlabathi "isikhashana" ibe nezimo ezithile "ezibucayi", okuholela e-arcing. Ukusetshenziswa kwendlela yokuqinisa ukumelana nephuzu lokungathathi hlangothi kokukhiqizwa kokugcwala kwe-grounding overvoltage kwakha isiteshi sokukhipha amandla (inkokhelo) kumthamo wegridi ukuya emhlabathini, futhi kujove amandla anamandla endaweni yephutha, okwenza iphutha eliphansi lithathe imvelo ye-resistance-capacitance, ukunciphisa kanye Umehluko we-engeli yesigaba se-voltage kunciphisa izinga lokuvutha kabusha ngemva kokuba i-current endaweni yephutha inqamule ku-zero futhi yephule isimo "esibucayi" se-arc overvoltage, ukuze i-overvoltage ikhawulelwe ngaphakathi kwe-2.6 izikhathi ze-voltage yesigaba, futhi ngesikhathi esifanayo kuqinisekisa ukuzwela okuphezulu kokuvikelwa kwephutha lomhlabathi Imishini inquma ngokunembile futhi inqamule amaphutha ayinhloko kanye nesibili omphakeli, ngaleyo ndlela ivikele ngempumelelo ukusebenza okuvamile kwesistimu.

Grounding ukumelana nekhabethe
Ngokuthuthuka okusheshayo kwamagridi kagesi asemadolobheni nasezindaweni zasemakhaya, izinguquko ezinkulu zenzeke esakhiweni segridi yamandla, futhi inethiwekhi yokusabalalisa elawulwa yizintambo iye yavela.I-ground capacitance current ikhule kakhulu.Uma kwenzeka iphutha lesigaba esisodwa ohlelweni, kuba namaphutha ambalwa futhi ambalwa abuyiselekayo.Ukusetshenziswa kwendlela yokuqinisa ukumelana akuzivumelanisi kuphela nezidingo eziyinhloko zokuthuthukiswa kanye noshintsho lwegridi yamandla ezwe lami, kodwa futhi kunciphisa izinga lokwahlukanisa lemishini yokudlulisa amandla ngebanga elilodwa noma amabili, kunciphisa ukutshalwa kwezimali kwegridi yamandla iyonke.Sika iphutha, cindezela i-resonance overvoltage, futhi uthuthukise ukuphepha nokuthembeka kwesistimu yamandla.
