Siea molaetsa
Li-transformer tsa motlakase li hlile li bohareng ba hore na re fumana motlakase joang ho tloha sebakeng se seng ho ea ho se seng. Li re lumella hore re tsamaise matla a motlakase hantle lipakeng tsa li-circuits ka ho nyolla motlakase holimo kapa tlase, kaofela ha tahlehelo e ntse e le tlase.
1. Transformer ke eng le hore na e sebetsa joang
1.1 Tlhaloso ea Motheo ea Transformer
Transformer, motheong oa eona, ke sesebelisoa se tsitsitseng-ha ho letho le sisinyehang. Ha ho likarolo tsa mochini, ha ho potoloho; matla a motlakase a fetisoang ho tloha potolohong e 'ngoe ea AC ho ea ho e 'ngoe. Bonolo boo ke hantle hore na ke hobane'ng ha mokhoa ona o sebetsa hantle.
Seo e hlileng e se etsang ke shift voltage le maemo a hona joale. Le ts'ebetso eo e nyane-ea molumo? Ke ka lebaka leo motlakase o ka romelloang libakeng tse telele ntle le tahlehelo e kholo ea motlakase tseleng.
1.2 Molao-motheo oa ho Kenyelletsoa ha Electromagnetic
Boselamose bo ka morao ho transformer ke Molao oa Faraday oa Induction ea Electromagnetic. Lintlha ke tsena:
Ha AC e feta har'a matsoelintsoeke a mantlha, e baka phetoho ea makenete bohareng.
Phetoho ena e fetohang e ntan'o "hlohlelletsa" motlakase sebakeng sa bobeli, 'me motlakase o ipapisitse le karo-karolelano lipakeng tsa mantlha le tsa bobeli.
Karolo e thahasellisang? Voltage le hona joale li hokahane ka tsela e fapaneng. Kahoo, haeba motlakase o nyoloha, matla a hona joale a theoha. 'Me haeba motlakase o theoha, hona joale o nyoloha. Ke ka lebaka leo li-transformer li ka fetolang matla ho eng kapa eng eo sistimi e e hlokang.

6. Ntho e 'ngoe le e' ngoe eo U Lokelang ho e Tseba ka Power Transformers
Li-transformer tsa motlakase ke mechini e rarahaneng, 'me ho utloisisa litsamaiso tsa tsona tsa mantlha, tse tsoelipanang, tse pholileng le tsa ho kenya letsoho ke senotlolo sa ho li rala, ho li sebetsa le ho li boloka ka nepo.
6.1 Mefuta ea Konokono le Litlhophiso tsa Maqhubu
Ea mantlha
Li-transformer li sebelisa mefuta e fapaneng ea mantlha ho latela matla a motlakase, matla le litlhoko tsa mochini.
Tse tlwaelehileng-mehato e meraro:
Tse tharo- tsa mantlha
Maoto a mahlano-a mantlha
Kaho ea mantlha:
Li-cores tsa laminated ho fokotsa tahlehelo ea hona joale ea eddy
Li-cores tsa Toroidal (tse roliloeng) bakeng sa moralo o kopaneng le lerata le tlase
Lisebelisoa tsa mantlha:
Litšepe tsa silicon tse batang-- tse tloaelehileng bakeng sa li-transformer tse ngata
Amorphous alloy steel - e sebediswa ho boloka matla-, le ho fokotsa{1}tahlehelo e tlase.
Ho tsokotsa moea
Mapheo a phahameng-matla a motlakase (HV) hangata ke a terata-e leng maqeba 'me a sebelisa layer, sectional, kapa sectional-layer mekhoa ea ho mamella voltage le matla a makhutšoane{3} a potoloho. Maqhubu a tlase-matla a matla (LV) hangata a foil-maqeba 'me a sebelisa mapheo a sa khaotseng kapa a helical ho sebetsana le maqhubu a maholo a nang le leakage e fokolang.
Lisebelisoa tsa li-conductor:
Koporo - conductivity e phahameng, e sebelisoang hangata
Aluminium - e bobebe, khetho ea moruo bakeng sa li-transformer tse ling
Tlhokomeliso: Maqhubu a Wire-HV windings a ntlafatsa boemo ba motlakase, athe foil{1}} mapheo a LV a fokotsa ho lutla le tahlehelo ea koporo.
6.2 Mekhoa ea ho Pholisa
Ho pholisa ha se taba ea boikhethelo bakeng sa li-transformer-ho bohlokoa. Ho sebetsa hantle ho itšetlehile ka eona; bophelo ba tšebeletso bo itšetlehile ka eona. Mefuta e fapaneng ea li-transformer, ka tlhaho, e itšetlehile ka mekhoa e fapaneng ea ho pholisa.

Ha e le hantle hore na mekhoa ena e bolela eng: ONAN e sebelisa phepelo ea oli ea tlhaho le moea o pholileng oa tlhaho-ha e na lipompo, ha e na lifenehi. ONAF e ntse e itšetlehile ka phallo ea oli ea tlhaho empa e eketsa moea o qobelloang ho tlosa mocheso kapele. OFAF e tsoela pele ho feta, e qobella ho potoloha ha oli le moea bakeng sa ho tlosa mocheso o mongata.
Ha e le hantle, boholo le boemo ba voltage li etsa qeto ea ntho e 'ngoe le e' ngoe. Hangata li-transformer tse kholo tse phahameng-li hloka ONAF kapa OFAF ho laola khatello e phahameng ea mocheso, athe lisebelisuoa tse nyane, -tse phahamisitsoeng, kapa pad{3}li-pad{3}li ka sebetsa ka ts'epo ka ONAN kapa KNAN feela.
6.3 Lisebelisoa tsa Insulation le Oli ea Transformer
Sistimi ea Insulation:
Pampiri – mosireletsi oa setso oa matsoeli, hangata a kopanngoa le oli ka har'a oli-li-transformer tse qoelitsoeng
Letlapa la ho tobetsa – le sebedisoa e le sebaka sa sebaka kapa se tshehetsang dipakeng tsa maqhubu
Epoxy Resin – e tholahalang ho li-transformer-e omileng, e fana ka matla a phahameng a mochini, e thibela mongobo, le ts'ireletso ea mollo.
Oli ea Transformer
Oli ea liminerale-e ntse e le khetho ea khale bakeng sa oli-li-transformer tse qoelitsoeng. E fana ka insulation, e tlosa mocheso; o etsa mesebetsi ka bobeli ka botšepehi.
Oli ea FR3, eo hape e bitsoang oli ea ester ea tlhaho, e nka tsela e tala. Biodegradable, e sebetsana le mocheso o phahameng, o betere bakeng sa tikoloho.
Oli ea maiketsetso ea ester e lutse pheletsong e phahameng-matla a matla a dielectric, a tsitsitseng ka mocheso, hangata a sebelisoa maemong a khethehileng kapa a boima.
Ka har'a oli-li-transformer tse qoelitsoeng, oli ha se setlatsi feela; e etsa insulate le ho pholisa ka nako e le 'ngoe. Li-transformer- tsa mofuta o omileng li sebetsa ka tsela e fapaneng-ha li na oli, li kenya moea feela le boroku li hlokomela mocheso.
6.4 Ho hloleha ho Tloaelehileng ha Li-Transformer tsa Matla
Ke ka seoelo ho hloleha ho hlahang feela. Tse ngata li tlameletsoe khatellong ea mocheso, liphoso tsa motlakase, ho apara ha mechine, kapa maemo a thata a tikoloho. Ha nako e ntse e ea, likhatello tsena lia eketseha.
Ka holimo: mesebetsi ea tlhokomelo ea thibelo. Tlhahlobo ea oli, litšoantšo tsa mocheso, tlhahlobo ea ho kenya letsoho, le DGA (Dissolved Gas Analysis) li tšoara mathata a ka bang teng pele a eketseha. Mehato e bonolo, empa e etsa phapang e kholo.
7. Likopo tsa Transformers ho AC Power Systems
Li-transformer{{0}li teng hohle litsing tsa motlakase tsa AC. U li bona lifemeng tsa motlakase, moo li-transformer-tse nyolohang li sutumelletsang motlakase ho ea holimo; hobaneng? Ho etsa hore -phetiso ea sebaka se selelele e sebetse hantle haholoanyane.
Ho latela mehala ea phetisetso le ho aba, ba etsa se fapaneng: theola motlakase ho ea maemong a bolokehileng, a ka sebelisoang-libaka tsa liindasteri, matlo, libaka tsa boahelani, kaofela.
Ka har'a lifeme le lits'ebeletso tsa khoebo, ba boloka mechini e ntse e sebetsa, ho fepa likoloi tsa makoloi, likhoele tsa tlhahiso, eng kapa eng e hlokang matla a tšepahalang.
Le lefats'eng la kajeno la matla{{0}lipolasi tsa moea, lipaka tsa letsatsi, li-grid tse bohlale-li ntse li le mosebetsing, li thusa ho kopanya lintho tse ka nchafatsoang, ho beha leihlo, ho etsa hore ho khonehe ho iketsetsa lintho.
Qetello
Li-transformer tsa motlakase ha se feela mabokose a tsitsitseng holim'a marang-rang. Ke mokokotlo oa phallo ea motlakase{1}ho o boloka o bolokehile, o tsitsitse, o sebetsa hantle. Ho tseba mefuta, mokhoa oa ho li kenya, ho li hlokomela, ho li lokisa-ke tsela eo lienjineri le li-operator li li etsang hore li tšoarelle nako e telele, li sebetse hantle, le ho boloka tsamaiso eohle e tsitsitse, leha mojaro kapa maemo a fetoha.
