Ka mor'a hore u kenye transformer ea hona joale e arohaneng, u lokela ho etsa bonnete ba hore e sebetsa kamoo ho lebeletsoeng kateng. Ho etsa liteko le ho netefatsa ts'ebetso ho u thusa ho fumana mathata kapele le ho netefatsa hore sistimi ea hau e lula e bolokehile ebile e nepahetse. U ka latela mehato ena ea bohlokoa ho hlahloba transformer ea hau:
- Teko ea Karo-karolelano
U bapisa hona joale ka lehlakoreng le ka sehloohong le hona joale ka lehlakoreng la bobeli. Teko ena e bontša hore na transformer e fana ka tlhahiso e nepahetseng. Haeba karo-karolelano e tima, 'malo oa hau o ke ke oa nepahala. - Tlhahlobo ea Polarity
U hlahloba tataiso ea windings. Mohato ona o netefatsa hore hona joale o phalla ka tsela e nepahetseng ka transformer. Haeba o hokahanya polarity e fosahetseng, litekanyo tsa hau li ka ba morao kapa li fosahetse. - Tlhasimollo (Saturation) Teko
U eketsa motlakase 'me u shebelle ha motsoako oa transformer o qala ho tlala. "Knee point" ke moo mokokotlo o sa khoneng ho sebetsana le hona joale. Teko ena e u thusa ho tseba meeli ea transformer ea hau. - Teko ea ho hanyetsa Insulation
U lekanya hore na insulation e sireletsa lifensetere hantle hakae. Ho koala hantle ho u boloka u sireletsehile ho ts'oenyeho ea motlakase le ho thibela li-circuits tse khutšoane. - Maqhubu a Resistance Test
U hlahloba ho hanyetsa ha windings ea transformer. Haeba khanyetso e phahame haholo kapa e le tlase haholo, transformer e ka ba le bothata ka hare. - Teko ea Moroalo
U kopanya transformer ho mojaro oa eona o lekantsoeng 'me u bone hore na e sebetsa tlas'a maemo a tloaelehileng. Teko ena e bontša hore na transformer e khona ho sebetsana le lisebelisoa tseo u rerang ho li sebelisa.
Keletso:Kamehla ngola liphetho tsa liteko tsa hau. Ho boloka litlaleho tse ntle ho u thusa ho bona liphetoho kapa mathata nakong e tlang.
Ho etsa liteko le ho netefatsa transformer ea hau e arohaneng ea hona joale ho u fa kholiseho ho instola ea hau. U sireletsa lisebelisoa tsa hau mme u netefatsa hore litekanyo tsa hau li lula li tšepahala. Haeba u fumana mathata leha e le afe nakong ea liteko tsena, li lokise pele u sebelisa transformer tsamaisong ea hau.
U ka khetha le ho kenya sesebelisoa sa hona joale se arohaneng ka kholiseho ha u latela mehato ena:
- Hlahloba maemo a hau a hona joale le litlhoko tsa mojaro.
- Khetha sehlopha sa ho nepahala le lisebelisoa tsa mantlha.
- Sheba hore na li-cable li lumellana joang le litifikeiti tsa polokeho.
- Itokisetse ho kenya ts'ebetso e sireletsehileng le ts'ebetso ea liteko.
Hopola: Litekanyo tse nepahetseng le mekhoa e sireletsehileng li sireletsa lisebelisoa tsa hau le sehlopha sa hau. Sebelisa tataiso ena ho etsa liqeto tse bohlale bakeng sa morero o mong le o mong.

Molemo o ka sehloohong oa ho sebelisa transformer ea hona joale e arohaneng ke efe?
U ka kenya transformer ea hona joale e arohaneng ntle le ho khaola lithapo kapa ho tima motlakase. Moralo ona o o bolokela nako mme o boloka sistimi ea hau e sebetsa. U boetse u fokotsa kotsi ea likotsi tsa motlakase nakong ea ho kenya.
U tseba joang hore na u khetha sehlopha sefe sa ho nepahala?
U lokela ho hlahloba litlhoko tsa morero oa hau. Bakeng sa taolo ea litefiso kapa matla, khetha transformer e nang le liperesente tse tlase tsa liphoso, joalo ka sehlopha sa 0.5 kapa 1.0. Ho nepahala ho holimo ho u thusa ho fumana litekanyo tse tšepahalang le ho qoba liphoso tse theko e boima.
A na u ka sebelisa li-transformer tsa mantlha tse arohaneng kantle?
U ka sebelisa li-transformer tsa morao-rao tse arohaneng ka ntle haeba li na le libaka tse thibelang boemo ba leholimo. Kamehla hlahloba lintlha tsa sehlahisoa bakeng sa tšireletso ea mongobo le lerōle. Batla lintlha tsa IP joalo ka IP65 kapa ho feta bakeng sa ts'ebeliso ea kantle.
Ho etsahala'ng haeba u tlohela potoloho ea bobeli e butsoe?
Haeba u tlohela potoloho ea bobeli e butsoe, motlakase o phahameng o kotsi o ka eketseha. Sena se ka senya thepa ea hau mme sa u beha kotsing ea ho tsosoa ke motlakase. Kamehla boloka potoloho ea bobeli e koetsoe nakong ea ts'ebetso.
U lekola joang transfoma ea mantlha e arohaneng kamora ho e kenya?
U ka leka transformer ea hau ka ho lekola karo-karolelano ea hajoale, ho netefatsa polarity, le ho lekanya khanyetso ea insulation. Sebelisa metara ho bapisa lipalo. Rekota liphetho tsa hau ho latela ts'ebetso ha nako e ntse e ea.
