Boima ba oli ea transformer
Litšobotsi tsa mefuta eohle ea oli ea li-transformer li nkuoa e le ts'epo e ka tlase ea index ea density ho mocheso oa kantle le boleng bo tlase ba ntlha e teteaneng (mohlala, bakeng sa oli ea mofuta oa TKp, ea morao-rao ke -45).°C, le bakeng sa T-1500 - esita le -55 ° C).
Maemo a tloaelehileng a mafura a li-transformer a fapana ho latela boima ba oli ka har'a mefuta (0,84…0,89)×103 kg/m3. Lintlha tse ling tse amang density li kenyelletsa:
- Sebopeho sa lik'hemik'hale (ho ba teng ha li-additives, tse ka sehloohong ke ionol).
- Thermal conductivity.
- Viscosity (matla le kinematic).
- Thermal diffusivity.
Ho bala palo ea litšoaneleho tsa ts'ebetso, boima ba oli ea transformer bo nkoa e le boleng ba boitsebiso (haholo-holo, ho fumana maemo a likhohlano tsa ka hare tse amang matla a ho pholisa a mahareng).
Boima ba oli ea transformer e sebelisitsoeng
Ts'ebetsong ea ho tima lits'oants'o tsa motlakase tse ka bang teng ka har'a ntlo ea transformer, oli e silafatsoa ke likaroloana tse nyane ka ho fetesisa tsa motlakase, hammoho le lihlahisoa tsa karabelo ea lik'hemik'hale. Lithempereichara tse phahameng tsa sebakeng seo, li ka etsahala sebakeng se nang le oli. Ka hona, ha nako e ntse e ea, boima ba oli bo eketseha. Sena se lebisa ho fokotseha ha matla a pholileng a oli le ponahalo ea marokho a ka khonehang a ho khanna a fokotsang tšireletso ea motlakase ea transformer. Oli ena e hloka ho nkeloa sebaka. E etsoa ka mor'a lihora tse itseng tsa ho sebetsa ha sesebelisoa, seo hangata se bontšoang ke moetsi oa sona. Leha ho le joalo, haeba transformer e sebetsa tlas'a maemo a moeli, tlhokahalo ea ho nkeloa sebaka e ka hlaha pejana.
Bakeng sa lihlahisoa tse thehiloeng ho parafine, ho eketseha ha sekhahla sa oli ea transformer ho boetse ho bakoa ke hore lihlahisoa tsa oxidation (sludge) ha li khone ho qhibiliha 'me li lula ka tlas'a tanka. Sediment ena e sebetsa e le tšitiso tsamaisong ea ho pholisa. Ho feta moo, palo e feteletseng ea metsoako ea macromolecular e eketsa ntlha ea ho tšela oli.
Ho lekola boleng ba 'nete ba index ea density ho etsoa ka tatellano e latelang:
- Mehlala ea oli e nkuoa libakeng tse fapaneng tsa tanka. Sena se bakoa ke hore ho senyeha ha dielectric ho fapana ka tsela e fapaneng le metsi a eona, ho bolelang hore matla a dielectric a oli ea transformer a fokotseha ha metsi a ntse a eketseha.
- U sebelisa densitometer, lekanya boima ba oli 'me u bo bapise le litekanyetso tse khothalletsoang.
- Ho ipapisitse le palo ea lihora tseo oli e ntseng e sebetsa ka har'a transformer, e ka ba molumo o boletsoeng oa oli e ncha, kapa ea khale e tlhotliloeng ka hloko.
Viscosity ea oli ea transformer
Viscosity ke tšobotsi e amang ho fetisoa ha mocheso ka har'a letamo la oli. Palo ea viscosity e lula e le paramente ea bohlokoa ea ts'ebetso ha u khetha oli bakeng sa mofuta ofe kapa ofe oa sesebelisoa sa motlakase. Ke habohlokoa haholo ho tseba viscosity ea oli ea transformer ka mocheso o feteletseng. Ho ea ka litlhoko tsa maemo a mmuso, boikemisetso ba kinematic le viscosity e matla e etsoa ka mocheso oa 40.°C le 100°C. Ha transformer e sebelisoa haholo ka ntle, tekanyo e eketsehileng e boetse e etsoa ka mocheso oa 15.°C.
Ho nepahala ha boikemisetso ba viscosity ho eketseha haeba index ea refractive ea medium e boetse e hlahlojoa ka ho bapisa le refractometer. Phapang e nyane ea boleng ba viscosity e fumanoang lithempereichara tse fapaneng tsa liteko, oli e betere. Ho tsitsisa matšoao a viscosity, ho kgothaletswa hore nako le nako o tlose oli ea hydrotreat transformer.
