The transformer mounting pad core e amohela-moetso oa litho tse tharo, o tsamaellanang ka botlalo le 1500 kVA le sehlopha sa li-vector tsa Dyn1, 'me e lumellana le IEEE C57.12.34-2022. Tahlehelo e lekantsoeng ea ho se be le moroalo ke 1.395 kW feela (ka likhato tse 20) mme hona joale ha ho na moroalo o tlase joalo ka 0.13%, e bonts'ang ts'ebetso e ntle ea potoloho ea makenete le boleng ba thepa. Liphetho tsena li tsoa tlalehong ea tlhahlobo ea tloaelo (karolo ea 4.4), e pakang tahlehelo e tlase ea mantlha le ts'epo e phahameng. Tlhahiso e sebelisa tšepe ea silicon e khonang ho kenella ka bongata, e lahleheloang haholo ke lijo-thollo e nang le stacking e itirisang, e netefatsang ho tiea ho hong ho sa fetoheng le ts'ebetso ea makenete. Lintlha-khōlō tsa tlhahiso: thepa e khonang ho kenella ka mokhoa o phahameng, ho bokellana ka boiketsetso, moralo o tlase oa hysteresis.

2.2 Ho tsubella

Maqhubu ke aluminium, e nang le li-voltages tse lekantsoeng 34500‑400Y/230 V le mefuta e fapaneng ea ho theipi ± 2×2.5%, e tsamaellanang hantle le maemo a moralo. Li lumellana le litlhoko tsa IEEE C57.12.90-2021 bakeng sa ho hanyetsa ho se leka-lekane, matla a dielectric, le ho phahama ha mocheso. Ho ea ka tlaleho ea teko, boholo bo ka holimo ho HV winding resistance resistance ke 0.44% feela (hantle ka tlase ho moeli oa 4.88%). Teko ea motlakase e sebelisitsoeng e fetile ho 50 kV (HV) le 10 kV (LV) bakeng sa metsotsoana e 60; teko ea motlakase e hlahisitsoeng e fetile ho 30.8 kV e sebelisitsoeng / 69 kV e susumelitsoeng, 150 Hz bakeng sa metsotsoana e 48 ntle le ho senyeha. Ho sa le joalo, ka karolelano mocheso oa moea o nyoloha Ka tlase kapa ho lekana le likhato tse 65, sebaka se chesang se nyoloha Ka tlase kapa ho lekana le likhato tse 80, 'me oli e holimo e nyoloha Ka tlase kapa ho lekana le likhato tse 65, ho netefatsa ts'ebetso e bolokehileng ea nako e telele. Boleng bo tiisetsoa ke mechini e tsoelipanang ka boiketsetso e nang le taolo ea tsitsipano e sa khaotseng le tlhahlobo ea ho kenella ka har'a li-turn-turn. Lintlha-khōlō tsa tlhahiso: li-automatic windings, li-insulation tse peli, sebopeho sa motlakase se phahameng.

2.3 Tanka

Tanka ke sekoahelo se tiisitsoeng sa tšepe se entsoeng ka tšepe e bonolo, se nang le mekotla ea ho phahamisa le li-jacking pads, tse loketseng ho kenngoa kantle. Mmala le boholo li latela setšoantšo sa ho qetela (Munsell 9 GY 1.5 / 2.6 thepa e tala). E lumellana le litlhoko tsa IEEE C57.12.34 bakeng sa matla a mochine le tšireletso ea ho senya. Tlaleho ea tlhahlobo ea leak e bonts'a hore kamora ho sebelisa khatello ea 15 kPa bakeng sa lihora tse 24, ho ne ho se na ho lutla kapa ho senyeha ho sa feleng, ho tiisang botšepehi ba tanka. Netefatso ea boleng e kenyelletsa tlhahlobo ea weld ea 100% le lesela le hanyetsanang le ho bola. Lintlha-khōlō tsa tlhahiso: moralo oa sekoaelo se cheselitsoeng, teko ea ho lutla ha khatello ea lihora tse 24, pente ea boemo bo holimo e thibelang kutu.

2.4 Kopano ea ho Qetela

Kopano ea ho qetela e kopanya lihlahla tse tšeletseng tse arohaneng tsa HV, lihlahla tse tharo tsa resin LV, lithapo tse thellang, mochini o fetolang pompo o se nang matla, le - joalo ka ntlha ea bohlokoa ea projeke -li-fuse tsa Cooper tsa boleng bo holimo(mofuta oa bayonet le li-back-up tsa hajoale). Kopano e lumellana ka botlalo le lits'oants'o 'me e lumellana le mekhoa ea IEEE bakeng sa ho fana ka tumello le ho hokahanya ha mochini. Litekanyo tsa ho hanyetsa li-insulation li bontša: HV‑LV ho ea fatše 1.65 GΩ, LV‑HV ho ea fatše 1.58 GΩ, le HV&LV ho ea fatše 1.12 GΩ - hole ka holimo ho menyako e tloaelehileng ea tšireletso, ho paka botšepehi ba kopano. Boleng bo netefatsoa ka ho sebelisa likarolo tsa lebitso la Cooper, lirekoto tsa kopano tse ka lateloang, le ho lekola litorque tse bohlokoa habeli. Lintlha tsa bohlokoa tsa tlhahiso: li-fuse tsa Cooper, lihlahla tsa HV tse arohaneng, netefatso ea 100% ea ho hanyetsa insulation.

Liteko tsohle li etsoa ho latela IEEE C57.12.90-2021, ho koahela karo-karolelano, tahlehelo, impedance, polarity, dielectric, le ho tiisa. Liphetho tsa liteko li tsamaellana hantle le boleng bo tiisitsoeng: ho kheloha karo-karolelano ho theipi ea mantlha ke -0.08% ho ea ho -0.07% (Ka tlase kapa ho lekana le 0.5% e amohelehang); impedance e lekantsoeng ke 5.78% (mamello ± 7.5%); tahlehelo ea boima ka tekanyo ea 85 ke 9.836 kW; tahlehelo kaofela ke 11.231 kW. Habohlokoa ka ho fetisisa, transformer e finyella99.52% e sebetsang hantle– e fetang tlhokeho e tlwaelehileng ya DOE 2016 ya 99.48%, ho fihlella ka katleho sepheo sa projeke se baballang eneji. Li-voltage tsohle tse sebelisitsoeng, motlakase o kentsoeng, khanyetso ea insulation, le liteko tsa ho lutla li fetile tekong ea pele ntle le ho senyeha kapa ho lutla. Netefatso ea boleng e tšehetsoa ke laboratori e ngolisitsoeng ka molao ea ISO/IEC 17025, lisebelisoa tse hlophisitsoeng khafetsa, le ho rekota data ka boiketsetso. Lintlha-khōlō tsa tlhahiso: tlhahlobo e feletseng ea kamehla, ho tsamaisana le maemo a mang, ho lekanngoa ho sebetsa hantle ho feta DOE.

04 Ho paka le ho Romela

4.1 Ho paka

Ho paka ho sebelisa mohaho o matlafalitsoeng oa lehong o loketseng ho romelloa ka ntle ho naha kapa leoatleng. Transformer e romelloa ka nitrogen kapa oli ea FR3 ka hare ho thibela ho kenngoa ha mongobo. Ho paka ho lumellana le IEC 60076-10 le litlhaloso tsa bareki ba kantle ho naha. Pele o paka, ho etsoa tlhahlobo ea ho qetela ea botšepehi le teko ea ho boloka khatello ho netefatsa hore ha ho kotsi ea ho lutla. Likarete tsa li-desiccant le tsa mongobo li kenyelelitsoe bakeng sa ts'epo e eketsehileng nakong ea lipalangoang. Netefatso ea boleng e kenyelletsa lethathamo la ho qetela la tlhahlobo ea pono le lisebelisoa, hammoho le libuka tsa lipuo tse peli le litlaleho tsa liteko. Lintlha-khōlō tsa tlhahiso: matlafatso ea patsi-tšepe, tšireletso e tlatsitsoeng ke naetrojene/oli, ho sisinyeha le moralo o thibelang mongobo.

4.2 Ho tsamaisa thepa

Pele ho romelloa, litekanyo le boima ba kantle li netefatsoa khahlano le setšoantšo sa ho qetela hore se lekane lijana tse tloaelehileng kapa literaka tsa flatbed, tse tsamaellanang ka botlalo le leano la thepa. Ho romelloa ka sekepe ho latela melao ea machaba ea thepa e kotsi ea maoatleng (haeba ho hlokahala) le litlhoko tsa litokomane tsa bareki. Tlhahlobo ea ho qetela ea ponahalo le palo ea lisebelisoa li etsoa, ​​​​ho tsamaea le tlaleho e feletseng ea teko, setšoantšo sa nameplate, le buka ea litaelo. Ho ts'epahala ha thepa ho netefatsoa ke balekane ba nang le boiphihlelo ba lisebelisoa tsa li-heavy-lift, ba nang le ts'ebetso ea GPS le inshorense e felletseng ea lipalangoang. Lintlha-khōlō tsa tlhahiso: phihlelo e khethehileng ea thepa e boima, ho latelloa ka botlalo, sephutheloana se feletseng sa litokomane.
