Sehlooho: Mokhoa oa ho Etsa Tlhokomelo ea Transformer
Li-transformer ke lisebelisoa tsa bohlokoa tsa motlakase kabong le phetisong ea matla a motlakase. Ka hona, tlhokomelo e nepahetseng ea hlokahala ho netefatsa ts'ebetso e ntle le nako e telele. Transformer e hlokometsoeng hantle ha e fane feela ka katleho e phahameng empa hape e fokotsa kotsi ea litšitiso tse ka bang litšenyehelo tse ngata tsa ts'ebetso. Sengoloa sena se tla hlahloba mekhoa le mehato e fapaneng e amehang tlhokomelong ea li-transformer, hammoho le mabaka a bohlokoa ba tlhokomelo ea kamehla.
Bohlokoa ba Tlhokomelo ea Transformer
Tlhokomelo ea li-transformer e bohlokoa ho boloka botšepehi le botšepehi ba li-transformer tsamaisong ea gridi ea motlakase. Tlhokomelo ea thibelo e ikemiselitse ho lemoha mathata pele ho hlaha tšenyo e kholo. Litšenyehelo tsa ho lokisa kapa ho nkela transformer e senyehileng sebaka li ka ba holimo haholo ha li bapisoa le tlhokomelo ea kamehla. Ho feta moo, ho tima ha motlakase ho bakoang ke ho hloleha ha transformer ho ka ba le litlamorao tse kholo moruong, haholo-holo bakeng sa liindasteri tse itšetlehileng ka phepelo ea motlakase e tsitsitseng.
Mekhoa ea Tlhokomelo ea Transformer
1. Tlhahlobo ea Pono
Mohato oa pele tlhokomelong ea transformer ke tlhahlobo ea pono. Tlhahlobo ena e bonolo haholo empa e bohlokoa haholo. Lintlha tse ling tseo u lokelang ho li hlahloba li kenyelletsa:
– Boemo ba 'mele ba transformer: Etsa bonnete ba hore ha ho na tšenyo ea 'mele e kang mapetso kapa ho lutla ha oli ea transformer.
– Likarolo tsa Insulator le bushing: Etsa bonnete ba hore ha ho na mapetso kapa matšoao a ho tsofala ho insulator le bushing.
– Boemo ba sistimi ea ho pholisa: Hlahloba radiator, fene, kapa pompo ea oli ho netefatsa hore ntho e 'ngoe le e 'ngoe e sebetsa hantle.
Tlhahlobo e bonahalang e boetse e dumella ho lemoha mafome kapa ditshila tse ka amang tshebetso ya transformer.
2. Teko ea Oli ea Transformer
Oli ea transformer e sebetsa e le sebaka se sireletsang mocheso le ho pholisa li-transformer. Boleng ba oli ea transformer bo tlameha ho hlahlojoa khafetsa ka liteko tsa dielectric, liteko tsa tšilafalo, liteko tsa metsi le liteko tsa asiti. Liteko tsena li tla fumana hore na oli e ntse e le boemong bo botle kapa e hloka ho nkeloa sebaka. Boleng bo bobe ba oli bo ka fokotsa bokhoni ba eona ba ho thibela mocheso le ho pholisa, e leng se eketsang kotsi ea ho hloleha ha ts'ebetso.
3. Tlhokomelo ea Mocheso
Mocheso o feteletseng ka har'a transformer o ka baka tšenyo ea ka ho sa feleng likarolong tse ka hare. Ka hona, ho beha leihlo mocheso ho bohlokoa. Litekanyetso tsa mocheso li lokela ho kenngoa libakeng tsa bohlokoa ka har'a transformer ho netefatsa hore mocheso o lula o le ka har'a meeli e sireletsehileng. Haeba mocheso o phahama ka tšohanyetso kapa o bontša boleng bo sa tloaelehang, ho ka ba le bothata ka sistimi ea ho pholisa kapa ho jara boima bo feteletseng bo hlokang tlhokomelo e potlakileng.
4. Teko ea Thermography
Thermography ke mokhoa o sebelisoang ho lemoha ho chesa haholo ntle le ho ama likarolo tsa transformer. Ka ho sebelisa khamera ea mocheso, litsebi li ka bona litšoantšo tsa mocheso tse bontšang libaka tse chesang tse ka 'nang tsa bontša bothata. Tlhokomelo ena ea mocheso e sebetsa hantle haholo ho fumaneng mathata a sa bonahaleng mahlong.
5. Tekanyo ea Khanyetso ea Insulation
Khanyetso ea ho thibela ho ruruha ha transformer e tlameha ho lekanyetsoa ho netefatsa hore ho thibela ho ruruha ho boemong bo botle. Tekanyo ena hangata e etsoa ho sebelisoa Megger kapa sesebelisoa se seng sa ho lekanya ho thibela ho ruruha. Ho fokotseha ha khanyetso ea ho thibela ho ruruha ho ka bontša mongobo kapa tšilafalo ho ho thibela ho ruruha, e leng se hlokang tlhokomelo e potlakileng.
6. Teko ea Hona Joale le ea Phokotso ea Motlakase
Teko ea hona joale ea ho fokotseha ha motlakase le teko ea ho fokotseha ha motlakase ke mekhoa e sebelisoang ho lekola boemo ba liswichi le likhokahano ka har'a transformer. Liteko tsena li lumella litsebi ho lemoha tšenyo efe kapa efe kapa ho senyeha ha liswichi le likhokahano tse ka amang ts'ebetso ea transformer.
7. Ho Hloekisa Nako le Nako
Litšila, lerōle le likaroloana tse ling li ka bokellana holim'a transformer 'me tsa sitisa ts'ebetso ea eona. Ho hloekisa khafetsa hoa hlokahala ho thibela bothata bona. Sebelisa lesela le hloekileng le thepa e loketseng ea ho hloekisa ho netefatsa hore likarolo tsohle ha li na lithōle. Likarolo tse hlokang ho hloekisoa li kenyelletsa radiator, li-bushings le li-terminal tsa khokahano.
8. Ho Nkela Likarolo tse Senyehileng Sebaka
Likarolo tsa transformer tse bontšang matšoao a tšenyo li lokela ho nkeloa sebaka hang-hang. Phetolo ena e tlameha ho etsoa ka hloko 'me ho sebelisoe likarolo tse fihlelang litlhoko tsa moetsi. U se ke ua emela ho fihlela tšenyo e ba mpe haholo, kaha sena se ka lebisa tšenyo e mpe haholo.

9. Ho Nkela Likarolo tse Senyehileng Sebaka
– Hlalosa karolo e senyehileng mme o lokise karolo e loketseng e nkelang sebaka.
– Etsa phetolo ka hloko ho latela litaelo tsa moetsi.
Qetello
Tlhokomelo ea transformer e bohlokoa bakeng sa ho netefatsa ts'ebetso e ntle le e tšepahalang. Ka ho etsa liteko tsa pono, liteko tsa oli, tlhokomelo ea mocheso, thermography, litekanyo tsa ho hanyetsa ho kenella ha mocheso, liteko tsa phokotso ea hona joale le ea motlakase, ho hloekisa khafetsa, le ho nkela likarolo tse senyehileng sebaka, re ka lemoha le ho rarolla mathata esale pele. Ho kenya tšebetsong mekhoa e nepahetseng ea tlhokomelo ha ho ntlafatse feela katleho ea ts'ebetso ea transformer empa hape ho eketsa nako ea eona ea bophelo le ho fokotsa monyetla oa ho sitisoa. Ka hona, tlhokomelo e tsitsitseng ea transformer e bohlokoa bakeng sa ho netefatsa ho tsoela pele le ho tšepahala ha phepelo ea motlakase e sa sitisoeng.
