1000 kVA Oli e Tlatsang Pad Mounted Transformer-13.8/0.48 kV|Sebelisa 2024

01 Kakaretso

1.1 Semelo sa Morero

Ka 2024, 1,000 kVA pad-transformer e phahamisitsoeng e ile ea isoa United States bakeng sa Lefapha la Mabone la Masepala oa Belmont. Transformer ena-ea mekhahlelo e meraro e etselitsoe ho sebetsa ho 13.8 kV grounded wye (GrdY)/7.97 kV mme e na le ±2 × 2.5% no{10}}load tap changer (NLTC) bakeng sa ho feto-fetoha ha motlakase. Motlakase oa bobeli ke 0.208/0.12 kV, o etsa sehlopha sa YNyn0 vector, 'me o hlophisoa hore e be loop-feed transformer bakeng sa ts'ebetso ea netweke e tšepahalang.

Transformer ena ha e sebelise PCB mme e tletse FR3, oli e baballang tikoloho. E na le-moetso o shoeleng oa pele, oa loop-o etsang hore e bolokehe ebile e ts'epahala ts'ebetsong ea letsatsi le letsatsi. Kaha e phahamisitsoe-, e ka kengoa ka ntle holim'a konkreite, kahoo e sebetsa hantle litoropong, libakeng tsa bolulo, lirapeng tsa boikhathollo, libakeng tsa indasteri, boemafofaneng-o e bolela ka mabitso.

Karolo ea bohlokoa ea transformer ena ke sebopeho sa mabokose a eona a arohaneng: transformer ka boeona le likarolo tse phahameng- tsa motlakase{1}joaloka li-load switch, plug{2}}in fuse, le li-backup current-li-limiting fuse{4}}kaofela li ka litankang tsa tsona tse tiisitsoeng, li arotsoe ka karohano. Karolo ena e bile e na le sekontiri sa-ea lebota, se etsang hore ho hokahanya transformer le li-switches tsa mojaro ho be bonolo haholoanyane. Ho boetse ho bolela hore o ka boloka kapa oa fetola likarolo ntle le ho senya le likarolo tse ling, tse hlileng li leng bonolo. Moralo ona o etsa hore ho be bonolo ho lokisa le ho fetola karolo, ntle le ho ama ts'ebetso e tloaelehileng ea likarolo tse ling.

Ka kakaretso, transformer ena e tshesane, ho bonolo ho e kenya le ho e hlokomela,{0}}lerata le tlase-tahlehelo e tlase, e thibela{2}}bosholu, 'me e khona ho sebetsana le meroalo e boima. E fana ka ts'ireletso e felletseng 'me e loketse phepelo ea motlakase ea loop, phepelo ea matla a mabeli, kapa lisebelisoa tsa phepelo ea motlakase oa terminal, e sebetsang e le sesebelisoa sa phetoho ea motlakase, metering, matšeliso, taolo le ts'ireletso.

 Mokotla wa silicon-ya maoto a mahlano,{1}ya boleng bo hodimo; -tahlehelo e tlase, ho kenella haholo, ho thibela-botsofali.

 Maqhubu a koporo bakeng sa ts'ebetso e phahameng le ho tšoarella.

 Ho lokisa ka thata ho fokotsa ho thothomela, lerata le ho sotha ha lipalangoang.

 E tlatsitsoe ka FR3 e fokolang-e tukang, e eco{2}}mokelikeli o bonolo, o netefatsang ts'ebetso e sireletsehileng{3}}ea nako e telele ea kantle ho naha.

02 Tlhahiso

2.1 Ntlha ea bohlokoa

Koko e tla ba tse maoto a mahlano-e be a hahiloe ka boleng bo phahameng ka ho fetisisa,-e sa tsofalang, e batang-e thetheha, e sekametse lijo-thollo,{3}e se nang khatello ea maikutlo{3}mahala, a masesaane a silicon steel laminations. Moko oa mantlha o tla ba le ho kenella ho hoholo le tahlehelo e tlase ea hysteresis. Li-lamination tsa tšepe li lokela ho kenngoa hantle 'me li be le bokaholimo bo boreleli mathōkong. Letlapa le leng le le leng le tla ba le bokaholimo bo sirelelitsoeng, bo ke keng ba mamella oli e chesang ea transformer.

Mokotla o tla tlamelloa ka thata-thata le ho thibeloa ho thibela ho sisinyeha ho senyehang, ho kena-kenana le phallo ea oli, maemo a lerata a sa rateheng, le ho kheloha ha potoloho e khutšoanyane le ho tsamaisa thepa. Mokotla o lokela ho theoa ka mokhoa o sireletsehileng ka tanka.

2.2 Ho tsubella

Li-winding tsa transformer li entsoe ka koporo. The foil-maqeba a tlase{2}moetso oa motlakase o eketsa bokaholimo bakeng sa ho ntša mocheso hantle, o ts'ehetsa ts'ebetso e tsoelang pele{3}}ea phalliso e phahameng. E netefatsa kabo e tšoanang ea hajoale, e matlafatsa botsitso ka kakaretso, e hanela matla a motlakase a tsoang lipotolohong tse khutšoane, e fokotsa tahlehelo ea ho lutla, 'me e theola ho phahama ha mocheso ka har'a mapheo. Motsoako ona o ntlafatsa katleho le ho lelefatsa bophelo ba tšebeletso ea transformer.

2.3 Tanka

Tanka ea transformer ha e kenelle boemo ba leholimo, tšepe e cheselitsoeng, e tiileng-ea mokelikeli e kentsoeng holim'a skid base bakeng sa ho thellisa kapa ho thellisa, e nang le lihoko tsa ho phahamisa le lisebelisoa tsa ho phunya. E na le liphaposi tse peli tsa koporo- tse shebileng fatše, tse shoeleng{3}}ka pele tse nang le mamati a lihokelo, litšepe, le lisebelisoa tsa koporo. Li-radiator tsa tubula li cheselitsoe ka ho sa feleng ka morao. Menyako e ka buloa ka likhato tse 150 bakeng sa tlhokomelo e sireletsehileng. Bokaholimo bo entsoe ka lehlabathe, bo hloekisitsoe ka hare, 'me bokantle bo koahetsoe ka primer le likarolo tse peli tsa ho qetela (min{8}} mils) ho Munsell Green 7GY 3.29/1.5, e nang le tšireletso e eketsehileng tlase le sill.

2.4 Kopano ea ho Qetela
