Momwe Mungasankhire Kukula kwa Dongosolo Losungira Mafuta a Transformer

Chiyambi​

Mu ntchito za transformer yapakati ndi yapamwamba, makina osungira mafuta ndi ofunikira kwambiri poteteza chilengedwe, kutsatira malamulo, komanso chitetezo cha ntchito. Ku JZP, timapanga njira zolimba zosungira mafuta zomwe zimagwirizana ndi zosowa zapadera za ma transformer a mafakitale ndi ofunikira. Bukuli likufotokoza mfundo zazikulu ndi njira zodziwira kukula koyenera kwa makina osungira mafuta a transformer, kuonetsetsa kuti akugwirizana ndi miyezo yapadziko lonse lapansi komanso zofunikira za polojekiti.

Zinthu Zofunika Kwambiri Zomwe Zimakhudza Kukula kwa Dongosolo Losungira Zinthu​

 

Kuchuluka kwa Mafuta a Transformer​

 

Mfundo Yaikulu: Dongosolo losungiramo zinthu liyenera kukhala ndi 100% ya mphamvu yaikulu ya mafuta a transformerpansi pa mikhalidwe yabwinobwino ndi 110% panthawi ya moto(kuphatikizapo madzi ozimitsa moto ndi mvula)

 

Kuwerengera Chitsanzo:

 

Transforma ya 110 kV yokhala ndi mphamvu ya mafuta ya matani 30 (≈34 m³) imafuna mphamvu yosungira mafuta. 37.4 m³(34 m³ × 1.1) kuti ikwaniritse miyezo yotetezera moto.

 

Buku Lothandizira Malamulo:

 

GB50060-2008imalimbikitsa kuti machitidwe oletsa Transformer Yakunjamafuta okhala ndi mphamvu ya ≥1,000 kg ayenera kusungidwa60% ya kuchuluka kwa thanki lalikulu kwambiringati kulekanitsa mafuta ndi madzi kukuchitika.

 

Mikhalidwe Yokhudza Malo Omwe Ali​

 

 

Kukhazikitsa M'nyumba ndi Panja:

 

Ma transformer amkati (monga m'malo osinthira magetsi) nthawi zambiri amafunika kusungidwa pang'ono chifukwa cha malo olamulidwa, pomwe machitidwe akunja ayenera kuwerengera mvula ndi kulowa kwa nthaka.

 

Malo Ochotsera Chitetezo cha Moto:

 

Sungani mtunda wochepera mamita 1.5pakati pa ma transformer ndi makoma oyaka moto, ndi Mita imodzi kupitirira m'mphepete mwa transformerkufalikira kwa madzi a moto

 

Zinthu Zaukadaulo ndi Zachilengedwe​

 

Kutha Kunyamula Dothi: Yesani mtundu wa nthaka (monga dongo, miyala) kuti mudziwe kukhazikika kwa maziko ndi zofunikira pa madzi

 

Mphamvu ya Mvula: Pa machitidwe akunja, werengerani kuchuluka kwa mvula pogwiritsa ntchito deta ya nyengo yakomweko (monga, 100 mm/ola m'madera otentha).

 

 

Njira Yowerengera Kukula kwa Gawo ndi Gawo​

 

Dziwani Kuchuluka kwa Mafuta​

 

Unikani zojambula zaukadaulo za transformer kuti mudziwe kuchuluka kwa mafuta (monga malita 10,000 pa unit ya 60 MVA).

 

Gwiritsani Ntchito Zofunikira Zoyang'anira​

 

Kutsatira Malamulo a SPCC: Pa malo oyika mafuta ku US, tsatirani lamulo la EPA la 110% (kuchuluka kwa mafuta + 10% yaulere)

 

Miyezo ya ku China:

 

GB50053-2013: Imafunika kusungidwa kwa 20% kwa ma transformer amkati okhala ndi mafuta ≥100 kg, kukwera kufika pa 100% ngati madzi otuluka sakugwira ntchito.

 

Werengani Kuchuluka kwa Kusunga​

 

Fomula:

 

Muchiwerengero​=(Mumafuta​×1.1)+(Mumadzi​×0.35)

 

Madzi_V: Kuchuluka kwa madzi a moto (malo ozungulira × kuchuluka kwa madzi otuluka × nthawi).

 

0.35: Gawo lopanda kanthu la chosungira chodzaza ndi miyala (40% porosity)

 

Kapangidwe ka Ma Transformers Ambiri​

 

 

Sakanizani kuchuluka kwa mafuta a ma transformer ophatikizidwa ndipo onjezerani 20% yowonjezera kuti muwonjezere mtsogolo.

 

 

Njira Zabwino Kwambiri Zopangira Kapangidwe ka Makina Osungira Zinthu​

 

Kusankha Zinthu​

 

Konkire Yolimbikitsidwa: Imagwiritsidwa ntchito m'nyumba chifukwa cha kukana moto komanso kulimba.

 

Ma Geomembrane LinersGwiritsani ntchito ma HDPE liners panja kuti mupewe kutayikira kwa nthaka

 

Mafotokozedwe a Gulu la Miyala​

 

Kukhuthala: ≥250 mm.

 

Kukula kwa Mwala: 50–80 mm m'mimba mwake kuti pakhale ma porosity abwino komanso kuchepetsa moto

 

Kuchotsa Madzi ndi Kulekanitsa Mafuta ndi Madzi​

 

 

Ikani mapaipi obowoka okhala ndi mainchesi ≥150 mm ndi zotchingira zachitsulo chosapanga dzimbiri kuti musefe zodetsa.

 

Kukana kwa Zivomerezi ndi Mphepo​

 

Pangani maboluti oteteza kuti asawonongeke 0.4 static friction coefficientndi katundu wokhudzana ndi malo enieni a chivomerezi

 

 

Mapeto​

Kusankha kukula koyenera kwa mafuta osinthira kumafuna kusanthula mosamala kuchuluka kwa mafuta, malamulo oyendetsera ntchito, ndi momwe malo amagwirira ntchito. Ku JZP, timagwiritsa ntchito zida zamakono zamakono komanso njira zabwino kwambiri zamakampani kuti tipereke machitidwe otetezera omwe amaika patsogolo chitetezo, kutsatira malamulo, komanso magwiridwe antchito abwino. Gwirizanani nafe kuti muwonetsetse kuti muli ndi malo abwino komanso apamwamba.Ma Transformers a Voltage amatetezedwa ku kutuluka kwa madzi, moto, ndi zoopsa zachilengedwe.
