1000/1150 kVA Distribution Transformer Substation-13.8/0.48 kV|USA 2025

01 Kakaretso

1.1 Tlhaloso ea Morero

1000/1150 kVA substation transformer e ile ea isoa Amerika ka 2025. Matla a lekantsoeng a transformer ke 1000/1150 kVA e nang le pholiso ea KNAN/KNAF. Motlakase o ka sehloohong ke 13.8 kV o nang le ± 2 * 2.5% tapping range (NLTC), motlakase oa bobeli ke 0.48GrdY / 0.277 kV, ba thehile sehlopha sa vector sa Dyn1.

The 2000/2300 kVA substation transformer e etselitsoe ho fana ka kabo ea motlakase e tšepahalang le e sebetsang hantle bakeng sa Junction House - 1. Transformer e tlatsitsoe ka FR3® dielectric fluid, oli e tšoarellang le e phahameng-e etsang hore ho be le botsitso, e lelefatsang nako ea bophelo ba lisebelisoa, 'me e fana ka polokeho ea oli ea tikoloho ha e bapisoa le e tloaelehileng ea oli.

Karolo e ka sehloohong ea tšireletso ea tsamaiso ena ke 5-amp neutral grounding resistor (NGR), e fokotsang phoso ea hona joale le e sireletsang transformer ho senya nakong ea liphoso tsa fatše. NGR e behoa leihlo ka 5: 5 ratio current transformer (CT) e nang le lintlha tse nepahetseng tsa C10, ho netefatsa hore ho na le phoso e nepahetseng le tšireletso ea tsamaiso.

E etselitsoe hore e tšoarelle nako e telele le ho latela maemo a indasteri, transformer ena e netefatsa hore ho fanoa ka motlakase ka mokhoa o tsitsitseng ha e ntse e etelletsa pele polokeho, botsitso le ts'ebetso e nepahetseng bakeng sa Junction House - 1.

02 Tlhahiso

2.1 Ntlha ea bohlokoa

Karolo e ka sehloohong ea-mehato e meraro-e ahiloe ka lishiti tsa tšepe tsa silicon tse stacked ho fokotsa tahlehelo ea hona joale le ho netefatsa ts'ebetso e phahameng ea makenete. Moetso ona o na le maoto le matsoho a mararo a otlolohileng a hokahantsoeng ka lijoko tse holimo le tse tlase, tse fanang ka tsela e leka-lekaneng ea khoheli bakeng sa-mohato oa boraro. Mokhoa o hlophisitsoeng-o matlafatsa botsitso ba mochini, o fokotsa-tahlehelo ea thepa, hape o ntlafatsa ts'ebetso ea transfoma. Popeho ea eona e matla le e momahaneng e e etsa hore e lokele {{8}lisebelisoa tse phahameng tsa phetisetso le kabo ea motlakase.

2.2 Ho tsubella

Moea oa LV:E entsoe ka foil ea koporo, e katiloeng ka thata, 'me e fana ka matla a makhutšoane-a potoloho le ho sebetsa hantle ha mocheso.

HV Winding:E hahiloe ka terata ea koporo e kentsoeng ka har'a{0}moetso oa mofuta, e netefatsang ho chencha ho ts'epahalang-ho{2}}ho fetola mokelikeli bakeng sa{3}}e phahameng e mamellang motlakase le botsitso ba mochini.

2.3 Tanka

Tanka e sebetsa e le sebaka se sireletsang, se entsoeng ka litšepe tse cheselitsoeng ka ho feletseng kapa liphanele tse matlafalitsoeng ho netefatsa botšepehi ba sebopeho ha ho ntse ho eketsa mocheso oa mocheso. Bokaholimo ba eona bo na le sandblasting le-layer anti{2}}corrosion coating bakeng sa-ea tšoarella nako e telele kantle. E tlatsitsoe ka-oli ea insulating ea boemo bo holimo, tanka e fana ka mohatsela oa motlakase le ho tsitsa hantle ha oli e potoloha. Kopano ea tanka e kenyelletsa lihlahla, matšoao a mocheso oa oli / boemo, lisebelisoa tsa ho imolla khatello, le relay ea Buchholz. Mabota a mathoko a kopanya li-radiator tse ntšitsoeng, tse nang le li-valve tsa drain le likou tsa sampole ka tlase, li etsa sistimi e felletseng ea ts'ireletso, pholiso le ho beha leihlo.

2.4 Kopano ea ho Qetela

Kopano ea ho qetela e kopanya li-core, HV/LV windings, le litsamaiso tsa ho kenella ka har'a tanka ea masenke ka mor'a ho omisoa ha vacuum le ho tlatsoa ka oli. Likarolo tsa bohlokoa joalo ka lihlahla, lisebelisoa tse futhumatsang, li-relay tsa ts'ireletso, le lits'ebetso tsa ho beha leihlo li kentsoe, li lateloe ke liteko tsa hermetic le liteko tse felletseng tsa ho netefatsa bots'epehi ba mochini, ts'ebetso ea motlakase le ts'epahalo ea ts'ebetso ho latela maemo.

4.1 Ho paka

Transformer ea seteishene sa motlakase e pakiloe ka tšepe-mohaho o kopantseng oa lehong, o phuthetsoeng ka filimi e thibelang mafome{1}'me e kenngoe ka lintho tse monyang- tse monyang. Lithapo tsa tšepe li tiisa bokantle, ka matšoao a ho phahamisa le mongobo-li-labels tse thibelang ho senyeha ha mechine le ho senyeha ha tikoloho nakong ea lipalangoang.

4.2 Ho tsamaisa thepa

The substation transformer e qala ka ho isoa boema-kepeng ka literaka tse boima{{0}, ka lisebelisoa tse khethehileng tse netefatsang botsitso. Ha e fihla boema-kepe ba likepe tsa likepe, e kenngoa ka har'a setshelo kapa rack e bataletseng, e matlafalitsoe, ebe e alafshoa bakeng sa ts'ireletso ea mongobo pele e romelloa ka sekepe sa setshelo. Nakong ea leeto, thepa e sirelelitsoe ka holim'a deki kapa moo ho ts'oaroang, ka nako ea sebele-ka leihlo la mocheso, mongobo, le ho thothomela ho netefatsa hore e fihla e bolokehile boema-kepeng.

05 Sebaka le Kakaretso

E le motheo oa litsamaiso tsa motlakase, li-transformer tsa rona li hlahella ka ts'epo e phahameng, ts'ebetso e phahameng, le nako e telele ea bophelo, ho netefatsa phetisetso e tsitsitseng ea matla lefatšeng ka bophara. Ka-theknoloji e tsoetseng pele le taolo e matla ea boleng, re fana ka litharollo tse etselitsoeng ho khotsofatsa litlhoko tse fapaneng. Ho khetha lihlahisoa tsa rona ho bolela ho amohela polokeho, ts'ebetso, le bokamoso bo tsitsitseng ba matla.
