02 Tlhahiso

2.1 Ntlha ea bohlokoa

Moko oa mantlha o sebelisa tšepe ea silicon ea CRGO e nang le moaho oa li-step-lap ho fokotsa tahlehelo ea hona joale ea hysteresis le eddy. Tahlehelo e lekantsoeng ea ho se be le moroalo (0.728 kW) le ha ho na moroalo hona joale (0.60%) li ka tlase ho 0.95 kW le 1.2%, li tsamaellana ka botlalo le ho lumellana le IEC 60076. Liteko tsa kamehla li netefalitse ts'ebetso e tsitsitseng ea mocheso (HV winding e lekana le 59.25 K le Les60 K) haholo le Les60.25 K (46.9 dB(A) khahlano le. 75 dB(A) moeli). Boleng bo netefatsoa ke tlhahlobo ea 100% ea thepa e kenang le taolo ea marang-rang. Ntlha ea bohlokoa ea tlhahiso ke tahlehelo e tlase, ea mantlha e khutsitseng e fetang litlhoko tse sebetsang hantle.

2.2 Ho tsubella

Li-windings li tsoa ho 99.9% ea koporo ea electrolytic bakeng sa conductivity e phahameng le matla a mochine. Tahlehelo ea meroalo (5.657 kW) le ho sitisa potoloho e khuts'oane (5.91%) li ts'oana le tse hlokahalang Ka tlase kapa ho lekana le 5.8 kW le 5.75% ±7.5%, tlasa IEC 60076. Liteko tsa dielectric tse fetisitsoeng ho kenyeletsoa matla a lehalima (75 kV), voltage e sebelisitsoeng (28 kV HV / LV) ho phahama ha mocheso e ne e le 59.25 K bakeng sa HV le 58.23 K bakeng sa LV (ka bobeli e le Ka tlase ho kapa e lekana le 60 K). Boleng ba moea bo laoloa ke ho lekola tsitsipano, tlhahlobo ea 100% ea ho kenya letsoho, le ho omisa vacuum pele ho tlatsoa oli. Ntlha ea bohlokoa ke bokhoni bo phahameng ba ho mamella potoloho e khuts'oane bakeng sa ts'ebeletso e thata ea kantle.

2.3 Tanka

Tanka ea tšepe e tiisitsoeng ka botlalo ha e na sebolokelo kapa mosamo oa naetrojene mme e fana ka tšireletso ea IP56. Ho phahama ha mocheso oa oli (48.89 K) ho ka har'a moeli oa 55 K, 'me tanka e fetisitse teko ea ho lutla ha lihora tse 15 kPa / 24 ntle le ho lutla, ho kopana le IEC 60076. Boleng bo tiisetsoa ka ho tjheseletsa ho laoloang, ho lemoha ho lutla ha parafine ea 100%, le sandblasting pele ho penta. Tanka e koahetsoe ka RAL 7035 polyurethane (bonyane 100 μm DFT) bakeng sa kutu le ho hanyetsa UV, e etsa hore e tšoanele libaka tse nang le letsoai le phahameng joalo ka Barrow Island.

2.4 Kopano ea ho Qetela

Setsi se kopantseng se kopanya likarolo tsohle tse boletsoeng ke morero: FR3 tikoloho ea tlhaho ester fluid (mollo o phahameng o moholo ho feta kapa o lekana le 300 degree, biodegradable, K-class), lebokose la cable le tlatsitsoeng ka khase la HV le likhokahano tse ka senyehang, lebokose la cable la LV le nang le mekoallo ea koporo e atolositsoeng le litšehetso, lebokose le nang le mochini o thibelang ho hema (lebokose la mohala) ho shebella mocheso oa oli, mocheso o tsoelipanang le khatello. Lisebelisoa tsohle li lumellana le litekanyetso tsa transformer 'me li lumellana le IEC 60076 le AS/NZS 60076. Liteko li netefalitse ts'ebetso e nepahetseng ea mocheso oa mocheso (WTI), khanyetso e tsitsitseng ea "no-load tap changer" (NLTC), 'me e fetisitse ho mamella mocheso oa potoloho ea bobeli. Boleng bo netefatsoa ka ts'ebetso ea FAT le tlhahlobo ea ho hula mabitso a bobeli. Ntlha ea bohlokoa ea tlhahiso ke mabokose a modular cable le lebokose la anti-condensation, le loketseng tikoloho ea lihlekehleke tse mongobo, tse phahameng tsa mocheso.

03 Teko

Liteko tsohle tsa tloaelo li entsoe ho latela IEC 60076 mme li pakiloe. Liphetho tsa bohlokoa: ha ho tahlehelo ea moroalo 0.728 kW (Ka tlase kapa e lekanang le 0.95), tahlehelo ea mojaro 5.657 kW (Ka tlase kapa e lekanang le 5.8), impedance 5.91% (5.75% ± 7.5%), ho phahama ha oli e kaholimo ho 48.89 K (Ka tlase ho kapa ho lekana le 55 K / 5), moea o nyolohang 52 K / 5. (Ka tlase kapa ho lekana le 60 K), matla a lehalima (75 kV) a fetisitsoe, matla a sebelisitsoeng (28/3 kV) a fetile, boemo ba molumo bo Tlase kapa bo lekana le 46.9 dB (A) ( Ka tlase kapa ho lekana le 75), le 15 kPa / 24h leak teko e fetisitsoeng ntle le ho lutla.

04 Ho paka le ho Romela

4.1 Ho paka

Transformer e pakiloe holim'a skid ea lepolanka kapa setsi sa tšepe se nang le sekoaelo se sa keneleng metsi le likhoele tsa tšepe tsa maemo a kantle ho naha. Li-bushings tsohle, li-cable box le lebokose la li-terminal li kenngoa ka li-caps tse sireletsang, 'me desiccant e kenngoa ka har'a mokotla o tiisitsoeng ho thibela mongobo o kenang. Ho paka ho ikamahanya le ditlhoko tsa ho romelwa ka ntle ho lewatle (AS/NZS) mme ho kenyeletsa tshireletso ya tshoso le mafome. Boleng bo tiisetsoa ke cheke ea ho qetela ea motlakase pele e paka, litokomane tsa lifoto, le sehokelo sa tlaleho e felletseng ea tlhahlobo le setšoantšo sa lebitso.

4.2 Ho tsamaisa thepa

Ho romelloa ho etsoa ka har'a sets'oants'o se bulehileng sa 40-ft kapa rack e sephara e nang le transformer e kopaneng ka botlalo. E sirelelitsoe ka liboutu tse tlase, litšepe tsa lehong, likhoele tsa tšepe le meseme e thibelang ho skipa. Khatello e ntle (moea o omileng kapa naetrojene) e bolokiloe nakong ea lipalangoang ho qoba ho kenella ha mongobo. Thepa e latela melao ea machaba e seng kotsi (FR3 ke mokelikeli oa tikoloho oa K-class). Letšoao la ho ts'oha le tlameletsoe pele le tloha 'me le hlahlojoe ha le fihla ho netefatsa hore ha le tšoaroe hampe.

05 Kakaretso

500kVA 11/0.415kV enatransformer e qoelisoang ka olie lumellana ka botlalo le litlhaloso tsa projeke ea tekheniki. E kenyelletsa FR3tikolohoOli, HV le mabokose a cable a LV (a morao-rao a na le mekoallo e atolositsoeng ea koporo le litšehetso), lebokose la li-anti-condensation, le likhokahano tsa bobeli tsa likhoele. Litekanyetso tsohle li lumellana le IEC 60076 le AS/NZS 60076. Ho tšepahala ho pakoa ke tlaleho ea tlhahlobo e tloaelehileng: tahlehelo e tlase ho feta e tiisitsoeng, likhahla tse lekaneng tsa ho phahama ha mocheso, liteko tsohle tsa dielectric le impulse li fetile, leak-tight, le lerata le tlaase haholo. Boleng bo netefatsoa ke ts'ebetso ea tlhahiso e ka latelloang ea ISO 9001. Ka tanka ea eona ea masenke e tiisitsoeng ka hermetically, ts'ireletso ea IP56 le likarolo tsa tikoloho e mongobo / letsoai, transformer ena e loketse hantle libaka tse pepeneneng tse kang Barrow Island, WA.
