Boemo ba insulation ea transformer

Joaloka lisebelisoa tsa bohlokoa tsa motlakase tsamaisong ea matla, boemo ba ho kenya letsoho ba transformer bo amana ka ho toba le ts'ebetso e sireletsehileng le e tsitsitseng ea tsamaiso ea matla. Boemo ba ho kenya letsoho ke bokhoni ba transformer ea ho mamella li-overvoltages tse fapaneng le matla a nako e telele a ho sebetsa nakong ea ts'ebetso, 'me ke ntlha ea bohlokoa e ke keng ea hlokomolohuoa moralo, tlhahiso, ts'ebetso le tlhokomelo ea transformer.

1. Tlhaloso ea boemo ba ho kenya letsoho ba transformer Boemo ba ho kenya letsoho bo bolela bokhoni ba sebopeho sa ho kenya letsoho sa transformer ho boloka botšepehi le tšireletseho ha e mamella li-overvoltages tse sa tšoaneng le nako e telele ea ho sebetsa ka nako e telele. Sena se kenyelletsa boemo ba motlakase bo ka mamelloang hammoho le sets'oants'o sa lehalima se sireletsang 'me ka ho toba se itšetlehile ka boholo ba motlakase oa Um oa thepa.

2. Sebopeho sa insulation sa transformer Ho ea ka hore na boemo ba ho koala ha moeli oa moeli o fela le ntlha e sa jeleng paate e tšoana, transformer e ka aroloa ka mekhoa e 'meli ea ho kenya letsoho: ho pata ka ho feletseng le ho kenngoa ka mekhahlelo. Transformer e nang le sebopeho se feletseng sa ho koala se na le boemo bo ts'oanang ba ho koala moeli oa moeli oa ho koala le ntlha e sa jeleng paate, e na le moeli o phahameng oa ho kenya letsoho, 'me e loketse li-transformer tse nang le maemo a phahameng a motlakase le libaka tse rarahaneng tsa ts'ebetso. Transformer e nang le sebopeho se kentsoeng ka sekhahla se beha maemo a fapaneng a ho kenella lipakeng pakeng tsa pheletso ea mohala oa matsoelintsoeke le ntlha e sa nke lehlakore ho latela litlhoko tsa 'nete tsa ho ntlafatsa moralo oa insulation le ho fokotsa litšenyehelo.

3. Ho lekoa ha boemo ba ho kenya letsoho ba transformer Ho etsa bonnete ba hore boemo ba mocheso oa transformer bo finyella litlhoko tsa moralo, ho hlokahala letoto la liteko tsa ho pata. Bakeng sa li-transformer tse nang le matla a motlakase a 220kV ho ea tlase, lebelo la motlakase la motsotso o le 1 le mamella teko ea motlakase le tlhahlobo ea motlakase oa impulse hangata li etsoa ho lekola matla a tsona a ho koala. Bakeng sa li-transformer tse nang le maemo a phahameng a motlakase, ho boetse ho hlokahala liteko tse rarahaneng tsa tšusumetso. Litekong tsa fektheri, teko ea ho mamella voltage hangata e etsoa ka makhetlo a fetang a mabeli a matla a lekantsoeng ho lekola ka nako e le 'ngoe ts'ebetso ea insulation ea mantlha le ho kenella ka longitudinal.

Ho phaella moo, ho lekanya ho hanyetsa ha insulation, ho monya karo-karolelano le polarization index ea matsoelintsoeke hammoho le bushing hape ke mokhoa oa bohlokoa oa ho lekola boemo ba kakaretso ba motlakase oa transformer. Litekanyo tsena li ka lemoha ka katleho mongobo o akaretsang oa sekontiri sa transformer, mongobo kapa litšila holim'a likaroloana, le mefokolo e tebileng ea ho kenella.

4. Lintlha tse amang boemo ba ho kenya letsoho ha transformer Nakong ea ts'ebetso ea transformer, lintlha tse amang boemo ba ho kenya letsoho haholo-holo li kenyelletsa mocheso, mongobo, mokhoa oa ho sireletsa oli le phello ea overvoltage. 1) Mocheso: Mocheso ke ntho ea bohlokoa e amang ts'ebetso ea ho kenya letsoho ea transformer. Ts'ebetso ea ts'ebetso ea thepa e sireletsang e fokotseha ka ho eketseha ha mocheso, 'me ho ba teng ha mongobo ka oli ho tla boela ho potlakise botsofali ba ho pata. Ka hona, ho laola mocheso oa ts'ebetso ea transformer le ho boloka boemo bo botle ba thepa e sireletsang ke mehato ea bohlokoa ea ho ntlafatsa boemo ba ho kenya letsoho.

2) Mongobo: Ho ba teng ha mongobo ho tla potlakisa botsofali ba thepa e sireletsang le ho fokotsa ts'ebetso ea eona ea ho pata. Ka hona, nakong ea ts'ebetso ea transformer, mongobo o teng o lokela ho laoloa ka thata ho thibela thepa e sireletsang hore e se ke ea ba mongobo.

3) Mokhoa oa ts'ireletso ea oli: Mekhoa e fapaneng ea ts'ireletso ea oli e na le litlamorao tse fapaneng ts'ebetsong ea insulation. Kaha karolo ea oli ea transformer e tiisitsoeng e kenngoa moeeng, e ka thibela ka katleho ho fetoha le ho hasana ha CO le CO2 ka oli, ka tsela eo ho boloka ts'ebetso e ntle ea oli e sireletsang.

4) Phello ea overvoltage: Phello ea overvoltage ke ntlha e 'ngoe ea bohlokoa e amang boemo ba insulation ba transformer. Ka bobeli overvoltage ea lehalima le overvoltage ea ho sebetsa e ka baka tšenyo ho sebopeho sa motlakase sa transformer. Ka hona, ha ho etsoa le ho sebetsa transformer, phello ea overvoltage e tlameha ho nkoa ka botlalo 'me mehato e ts'oanang ea ts'ireletso e lokela ho nkoa.

5. Mehato ea ho ntlafatsa boemo ba ho kenya letsoho ba transformer
Ho ntlafatsa boemo ba motlakase oa transformer, mehato e latelang e ka nkuoa:
1) Khetha lisebelisoa tsa boleng bo holimo tsa insulating: Lisebelisoa tsa boleng bo holimo tsa insulating li na le ts'ebetso e ntle ea ts'ireletso le bophelo bo bolelele ba ts'ebeletso, bo ka ntlafatsang haholo boemo ba motlakase oa transformer.
2) Ntlafatsa moralo oa insulation: Ho ea ka tikoloho ea 'nete ea ts'ebetso le litlhoko tsa transformer, ntlafatsa moralo oa ho kenya letsoho 'me u behe moeli oa insulation ka mokhoa o utloahalang ho netefatsa hore transformer e ka boloka ts'ebetso e ntle ea ho ts'oara tlas'a maemo a fapaneng a ts'ebetso.
3) Matlafatsa tlhokomelo le tlhokomelo ea insulation: Kamehla hlokomela le ho boloka insulation ea transformer, fumana hang-hang le ho sebetsana le mathata a ho kenya letsoho le mathata a botsofali, 'me u netefatse hore boemo ba motlakase oa transformer bo lula bo le boemong bo phahameng.
4) Adopt insulation boosting technology: Ka ho sebelisa theknoloji e matlafatsang insulation, joalo ka asoblique winding, spiral kapa cosine wave boosting, boemo ba ho kenya letsoho ba transformer bo ka ntlafatsoa haholo 'me matla a eona a ho thibela ho kena-kenana le mamello a ka ntlafatsoa.
Ka ho khetha lisebelisoa tsa boleng bo holimo, ho ntlafatsa moralo oa ho koala, ho matlafatsa ts'ebetso le tlhokomelo, le ho sebelisa theknoloji ea ho matlafatsa li-insulation, boemo ba transfoma bo ka ba teng. e ntlafalitsoe hantle, 'me bophelo ba eona ba ts'ebeletso bo ka eketsoa.
