Ikhabhinethi yokumelana nephuzu elingathathi hlangothi le-Transformer

Incazelo emfushane:

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.

Izingxenye zekhabhinethi yokumelana nephoyinti elingathathi hlangothi le-transformer iphuzu: indikimba yekhabhinethi (ikhabethe lenhlanganisela yohlobo lwebhokisi), isiguquli esiyisisekelo (ongakukhetha uma kungekho uhlelo lwamaphuzu angathathi hlangothi), isitha esiphansi, isiguquli samanje, isethi ephelele yokushintsha ummese wokuzihlukanisa, isilawuli esihlakaniphile (iyunithi yokuqapha ehlakaniphile) .
