Mabapi le ts’ireletso ea li-transformer tse qoelisoang ka oli, ho tsoa fekthering ea China
Mona, SPL, feme ea China transformer, e u fa leseli mabapi le ts’ireletso ea lipalangoang tse qoelisoang ka oli. Ho na le lisebelisoa tse 3 tsa mantlha tsa tšireletso:
1, relay ea khase: e sebelisetsoa 800kVA le ka holimo ho transformer e qoelitsoeng ka oli. Ha matla a khokahanyo a phepelo ea khase a le kholo ho feta 66VA kapa 15W mme pokello ea khase e le 250 ~ 300ml kapa ka har’a lebelo le behiloeng ka lebelo la oli, lebitso le ts’oanang le lona le lokela ho hokahanngoa. Sebopeho le boemo ba ho kenya mochine oa khase o lokela ho khona ho bona palo le ‘mala oa khase,’ me ho bonolo ho nka khase. E kenye ka keketseho ea 1.5% ea gradient. Sekoaelo sa tanka ea oli ea transformer ea 220kV le sona se lokela ho ba le 1 ~ 1.5% e ntseng e eketseha.
2, valve ea ho lokolla khatello: e sebelisetsoang 800kVA le ka holimo ho li-transformer; Ha khatello e ka lebokoseng la oli ea tsela e sireletsehileng ea moea kapa valve ea khatello ea khatello e fihla ho 5.07 × 104Pa, e lokela ho lokolloa ka botšepehi. Li-valve tse peli tsa khatello ea khatello li lokela ho behoa bakeng sa transformer e nang le 120000kVA le holimo.
3, valve, plug plug: lebota lohle la tanka ea transformer le lokela ho ba le valve ea sampole ea oli, 110kV, 90000kVA le 220kV, 63000kVA le ka holim’a bohareng ba lebota la tanka le eona e tlameha ho ba le valve ea sampole ea oli. Litanka tsa 315kVA ho ea holimo li tla ba le mochini o ntšang metsi ka tlase. Karolo e ka tlase ea tanka ea transformer e lokela ho ba valve e lekaneng ea ho ntša oli, 220kV transformer le eona e lokela ho ba le valve ea ho ntša oli ka kotsi. Transformer e tlameha ho ntša khase ha e tlatsa oli le tlhahlobo, kahoo karolo e ka holimo ea sekontiri sa transformer, radiator, bushing, joalo-joalo, e na le plug ea vent ho netefatsa polokeho ea transformer.
