Ho Fetola ka Oli ka ho Koenya Transformer: Temoho ea Tekheniki le Likarolo tsa Moralo

Transformer e qoelitsoeng ka oli Li-winding ke likarolo tsa bohlokoa litsamaisong tsa kabo ea matla, tse etselitsoeng ho fetisetsa matla a motlakase ka katleho ha ka nako e ts'oanang li netefatsa ts'epo le ho tšoarella. Ka tlase ke tlhahlobo e qaqileng ea sebopeho sa tsona, thepa le melao-motheo ea ts'ebetso, tse entsoeng ho latela maemo a indasteri le litlhaloso tsa tekheniki.

Mocheso o kaholimo oa transformer o qoelitsoeng ka oli o thibetsoe ho feta 95 ° C, ka kakaretso o thibetsoe ho feta 85 ° C, khetho e akaretsang ea ho kobeha ha transformer ea thepa ea lera la insulation ea sehlopha sa A, mocheso o phahameng ka ho fetisisa o lumelletsoeng oa thepa ea insulation ke 95 ~ 105 ° C, litlhaloso tsa ho futhumatsa tsa transformer tsa Chaena li ipapisitse le mocheso o sebetsang oa 40 ° C joalo ka ha maemo a tloaelehileng, ho kobeha ha mocheso o tloaelehileng oa khase o kenyelelitsoe ho 65 ° C, Ho phahama ha mocheso oa oli e kaholimo ho ea khaseng ho behiloe ka nepo ho 55 ° C, kahoo ho kobeha ho nang le khubu ea transformer ho kenyelelitsoe ho phahama ha mocheso oa oli ho 10 ° C.

Haeba mocheso o ka hodimo wa transformer e le 85 ° C, mocheso o kobehang ke 95 ° C; Haeba mocheso o ka hodimo e le 95 ° C, mocheso o kobehang o fihlile ho 105 ° C, e leng mocheso o fihletseng mocheso o phahameng ka ho fetisisa o dumelletsweng wa thepa ya lera la ho kwahela e kobehang. Mocheso o phahameng haholo o tla potlakisa botsofali ba thepa ya lera la ho kwahela e kobehang, o potlakise ho senyeha ha oli ya transformer, o lematse bophelo ba tshebeletso ya Transformer ea Kabos, esita le ho lebisa likotsing tsa polokeho.

Sistimi e matla ea potoloho ea oli e nang le moea o pholileng, mocheso o phahameng oa 75℃ o futhumatsa 35℃; Sistimi ea potoloho ea tlhaho ea oli, tšireletso ea mocheso o feteletseng, transformer e nang le moea o pholileng, mocheso o phahameng hangata ha o loketse hangata ho feta 85 ° C, mocheso o phahameng o ke keng oa feta 95 ° C o ke ke oa feta 55 ° C, haeba ho fumanoa hore boleng ba moeli bo feta litlhoko, bo lokela ho tlaleha hang-hang kemiso ea tlhahiso, tšebeliso ea mehato ea ho hanyetsa ea mojaro.

1. Tlhaloso le Mosebetsi oa Bohlokoa

Mabili a transformer a qoelitsoeng ka oli a entsoe ka likhoele tsa koporo kapa tsa aluminium tse kobehileng ho potoloha setsi sa tšepe sa silicon se laminated. Mabili ana a qoelisoa ka botlalo ka oli e sireletsang mocheso, e sebeletsang merero e 'meli: ho sireletsa motlakase le tsamaiso ea mocheso. Mabili a fetola tlhahiso ea motlakase o phahameng hore e be tlhahiso ea motlakase o tlaase (kapa ka tsela e fapaneng) ka ho kenya motlakase ka motlakase, ho nolofalletsa phetiso ea motlakase o sireletsehileng ho pholletsa le li-grid.

2. Sebopeho sa thepa

​Lisebelisoa tse Tsamaisang:

Koporo: E sebelisoa haholo bakeng sa ho winding ha motlakase o phahameng ka lebaka la ho tsamaisa ha eona motlakase ka tsela e phahameng le matla a mechini. Ho winding ha motlakase o tlase (≤500 kVA) hangata ho nka sebopeho sa cylindrical sa lera le habeli, ha bokgoni bo boholo (≥630 kVA) bo sebedisa di-configurations tsa double-helix kapa quadruple-helix ho ntlafatsa kabo ya hajwale.

Aluminium: E sebelisoa ka linako tse ling bakeng sa lits'ebetso tse nang le litšenyehelo tse tlase, leha e le hore ha e sebetse hantle joaloka koporo.
Ho kenya mocheso:

Lisebelisoa tse hanyetsanang haholo (mohlala, li-resin tsa epoxy, pampiri e thehiloeng ho cellulose) li arola li-winding ho tloha bohareng le ho tse ling.

Ho kenya mocheso ka mekhahlelo e mengata ho thibela lipotoloho tse kgutshwane tlasa kgatello ya mocheso kapa phetoho ya mechini.

3. Moralo oa Sebopeho

Tokisetso ea ho Fetoha:

Ho kobeha ha Concentric (Cylindrical): Ho tloaelehile ho di-transformer tsa mekhahlelo e meraro, moo ho kobeha ha motlakase o tlase ho bewang ka hare ho ho kobeha ha motlakase o phahameng ho fokotsa phallo ya ho dutla ha motlakase.

Ho kobeha ha lera le leqeba (Helical): Ho sebelisoa bakeng sa lits'ebetso tsa motlakase o phahameng, tse nang le lera le kopaneng ho fokotsa tahlehelo ea motlakase o tsoang ka har'a eddy.

Kopanyo ea ho Pholisa:

Mabili a kenyelletsa liphaephe tsa oli ho tsamaisa phallo ea mocheso ka mokhoa oa tlhaho kapa o qobelloang oa convection.

Litanka tsa oli tse nang le masenke li nkela li-conservator tsa setso sebaka, li lumella katoloso ea oli mochesong ha ka nako e ts'oanang li boloka tikoloho e koetsoeng.

4. Ntlafatso ea Ts'ebetso​

Moralo oa Tahlehelo e Tlase:

Li-Cores tsa Alloy tse sa fetoheng: Fokotsa tahlehelo ea hysteresis le ea eddy current (mohlala, li-transformer tsa letoto la S11-M li fumana tahlehelo e tlase ka 30% ho feta mehlala ea khale)

Sehlopha sa Khokahano sa Dyn11: E fokotsa ho sotha ha harmonic le ho ntlafatsa boleng ba matla ka ho fokotsa maqhubu a harmonic a boraro

Khanyetso ea Potoloho e Khutšoanyane:

Li-clamp tse matlafalitsoeng tsa ho kobeha le mekhoa ea ho kobeha e potolohang li ntlafatsa botsitso ba mechini nakong ea maemo a phoso.

Li-breather tsa silica gel le Buchholz relay li hlahloba ho se tsitse ha mongobo le phallo ea oli

5. ​Ts'ebeliso le Tlhokomelo​

Maemo a ho Tsamaisa Mosebetsi:

Liteishene tse nyane tsa indasteri, li-grid tsa motlakase tsa litoropong, le litsamaiso tsa eneji e nchafatsoang (mohlala, mapolasi a moea).

Matla a lekantsoeng a tloha ho 50 kVA ho isa ho 25,000 kVA, ka li-voltage tse fihlang ho 35 kV

Mekhoa ea Tlhokomelo:

Ho nka disampole tsa oli kamehla le tlhahlobo ea khase e qhibilihisitsoeng (DGA) ho lemoha ho senyeha ha insulation.

Litšoantšo tsa mocheso ho khetholla libaka tse chesang tse fumanehang libakeng tse kobehileng.

6. ​Lintlha tse Ncha ho Theknoloji ea ho Fetola Maqhubu​

Ho kenngoa ha Vacuum: Ho felisa lipokotho tsa moea nakong ea tlhahiso, ho ntlafatsa botšepehi ba ho thibela ho ruruha

Tlhokomelo e Bohlale: Li-sensor tse sebelisang IoT li latela mocheso oa ho potoloha le matla a mojaro ka nako ea sebele.
