1.1 Tlhaloso ea Morero

2000 kVA tse tharo phase pad mounted transformer e ile ea isoa USA ka 2025. Matla a lekantsoeng a transformer ke 2000 kVA le KNAN cooling. Matla a phahameng ke 13.8GrdY/7.97 kV e nang le ± 2 * 2.5% tapping range (NLTC), motlakase o tlase ke 0.48Y / 0.277 kV, ba thehile sehlopha sa vector sa YNyn0.

Pad mounted transformer ke sesebelisoa sa motlakase se feto-fetohang le se matla se etselitsoeng ho fihlela litlhoko tse fapaneng tsa marang-rang a sejoale-joale a kabo ea motlakase. E kentsoe holim'a letlapa la konkreite sebakeng sa fatše, e na le moralo o kopanetsoeng, o koaletsoeng o felisang tlhokahalo ea libaka tse koaletsoeng, e leng se etsang hore e be sebaka se loketseng bakeng sa libaka tsa litoropo le tsa litoropo tse nang le sebaka se fokolang. Transformer ena e na le lisebelisoa tse felletseng tse felletseng: oli ea FR3 ea ester ea tlhaho bakeng sa polokeho ea tikoloho le bophelo bo atolositsoeng, DOE-e lumellanang le matla-moetso o sebetsang hantle bakeng sa tšebeliso e fokotsehileng ea matla, e hahelletsoeng-ka sehahi bakeng sa ts'ireletso, le thebe e tsitsitseng bakeng sa ts'ebetso e ntlafalitsoeng ea ho koala. Lebokose le ka lehlakoreng- le fana ka tlhahlobo e bonolo ea boemo ba oli, mocheso, le lintlha tse ling tsa bohlokoa, ho thusa ho lokisoa le ho eketsa nako. Bokantle ba transformer bo felisitsoe ka pente-e tlositsoeng ka bosoeu (RAL 9003), e fanang ka matla a ho thibela kutu, mahlaseli a kotsi le boemo ba leholimo. E loketse lisebelisoa tsa radial kapa loop{12}}feed, e ka ikamahanya le litlhoko tse fapaneng tsa mojaro le maemo a ts'ebetso, ho tloha libakeng tsa bolulo ho isa litsing tse kholo tsa khoebo. Ka ts'ebetso ea eona e ts'epahalang, tlhophiso e felletseng, le ts'ebeliso e pharaletseng, transformer ena e kentsoeng ka pad ke tharollo e tšepahalang bakeng sa kabo ea motlakase e sebetsang hantle le e bolokehileng.

02 Tlhahiso

2.1 HV Bushing

The HV bushing for pad mounted transformers e bua ka Chardon's 15/25/35kV 200A class bushing insert, e etselitsoeng ho kopana le litsoe tse robehang le ho kopana le liliba tse tloaelehileng tse tsamaellanang le ANSI/IEEE 386. E thusa{5}}ho kenya le ho kenya sets'oants'o sa sets'oants'o, ho hloekisa le ho kenya li-silicone tse ncha{6}} e tiea ho 150-180lb-mo torque-ka #14 terata e fatše ea koporo bakeng sa polokeho. E loketse ts'ebetso ea loadbreak, e tlameha ho kenngoa/ho hlokomeloa ke basebetsi ba nang le tsebo ba nang le-lisebelisoa tse matla le lisebelisoa tse nepahetseng tsa ts'ireletso, tse netefatsang likhokahano tse tšepahalang tsa motlakase o phahameng.

2.2 LV bushing

The LV bushing for pad mounted transformers ke BFG-1/2500 resin dry-type bushing, ho latela maemo a moraorao a GB/T 4109 le IEC 60137. E na le 10kV AC e ommeng e mamellang voltage, 30kV lightning impulse voltage, ho hlajoa ha karolo Ka tlase kapa ho lekana le 10pC ho 1.2kV, -nako e khuts'oane ea nako ea mocheso ea 62.5kA/2s, 2000N cantilever load, le sebaka se lekanang le 3 ho feta 5mm kapa sebaka se lekanang. E etselitsoe hore e kenngoe ka mokhoa o tšekaletseng ka holim'a tin-plated conductive, e sebetsa maemong a -35℃ho +40 degree, e tla le ∅90×∅70×6 rectangular e koalang selikalikoe, 'me e bapisa litekanyo tsa ho buloa ha khabinete ka li-screw tsa 4-M12×50.

2.3 Tekanyo ea Boemo ba Oli

UHZ-01 Oil Level Gauge bakeng sa li-transformer tse kentsoeng li etselitsoe ho bonts'a boemo ba oli ka har'a-ho{3}}ho{3}}maoli a boima bo mahareng{10}}litanka tsa transfoma tse qoelitsoeng, tse nang le polokeho, ponahalo, ts'epo, le ts'ebeletso e telele ea bophelo. E sebetsa ho -40 ~ 80℃ambient thempereichara, e Ka tlase ho kapa e lekana le mongobo oa 90%, le Ka tlase kapa ho lekana le bophahamo ba 2000m, e hlokang ho kengoa e otlolohileng ntle le litšisinyeho tse bohale le matla a khoheli a matla. E entsoe ka float, lever e hokelang, sets'oants'o, tšepe ea makenete, le sesupo se nang le sebopeho se tiisitsoeng (sesupo se arolang ho phaphamala), se thibela ho thulana kapa ho otlolla / ho kobeha ha lehare le hokahanyang, mme e sebelisa O-ring bakeng sa ho tiisa tanka.

The 1'' flanged drain valve (e nang le 3/8'' sampler) bakeng sa pad mounted transformer ke ASME B1210-karolwana e ikamahanyang le maemo e lekantsweng bakeng sa kgatello ya ho sebetsa ya 1.6MPa, e sebetsa ho -20℃ho isa ho 150℃ka oli/non-rorod liquids/gase tse sa bola. E na le lebili la letsoho bakeng sa ts'ebetso, ho kenya flanged, le boema-kepe bo kopaneng ba 3/8 '': valve ena e thusa ho ts'oara oli ea transfoma e bolokehileng le sampole ea tlhokomelo ha e ntse e boloka ho tiisoa ha tanka, tlhophiso e loketseng ea pad e kentsoeng ea transformer.

2.5 Motšoantšisi oa Elbow

The elbow arrester e kopanya mochine oa metal oxide varistor (MOV) ka setsoe sa rabara ho fana ka tšireletso ea overvoltage. E na le peroxide{{1}e folisitsoeng ea EPDM thebe le semiconducting shield (e lumellanang le IEEE 386 bakeng sa interface le IEEE 592 bakeng sa ho sireletsa), e nang le #4AWG e flexible copper lead lead to faver surge current le kepisi ea tšepe e sa hloekang bakeng sa ho tiisa boemo ba leholimo. E etselitsoe lisebelisoa tsa ka tlas'a lefatše (mohlala, -likhabote tse kenngoeng tsa li-transformer tse kentsoeng, lisebelisoa tsa ho chencha vault), e fana ka tšireletso e sirelelitsoeng ka pele, e lelefatsa bophelo ba lithapo ha e kentsoe libakeng tse bulehileng tsa sisteme ea loop kapa ha ho fella li-radial system, 'me e fapanyetsana ka botlalo le lihlahisoa tsa bahlolisani ba IEEE 386.

03 Ho etsa liteko

Liteko tsa li-transformer tse kentsoeng (tse tsamaellanang le litekanyetso tsa IEEE C57) li hlahlobisisa: tekanyo ea ho hanyetsa maqhubu, netefatso ea karo-karolelano ea motlakase, ha ho na-tahlehelo ea mojaro / tlhahlobo ea hajoale, tlhahlobo ea tahlehelo ea meroalo, ho mamella motlakase (voltage e sebelisitsoeng / e kentsoeng), tlhahlobo ea ho hanyetsa le ho lutla ha khatello. Liteko tsena li netefatsa ts'ebetso ea motlakase, bots'epehi ba ho kenya letsoho, le ho tiisa tanka, ho netefatsa hore yuniti e fihlela litlhoko tsa ts'ireletso le ts'ebetso bakeng sa kabo e tšepahalang ea matla.
