Ama-Oyili Type Power Transformers ayizinto ezibucayi ezinhlelweni zesimanje zamandla kagesi, evumela ukuguqulwa okusebenzayo kwe-voltage kanye nokusatshalaliswa kwamandla kuwo wonke ama-grid.
Yiluphi uhlobo lohlobo lwamafutha?
Uhlobo lwe-oyili yama-torverformer luyidivaysi kagesi eqinile edlulisela amandla phakathi kwemibuthalo ngokungeniswa kwe-electromagnetic ngenkathi ugcina imvamisa engapheli. uwoyela ofaka uwoyela
- Umongo: Ngokuvamile i-silicon yensimbi ye-silicon ukunciphisa ukulahleka kwamanje kwe-Eddy.
- Uningings: Abaqhubi beCopper noma i-Aluminium bahlela emakhompiyutha aphambili nawesibili.
- Uwoyela ofaka uwoyela: Amafutha amaminerali, i-aillicone fluid, noma ama-bidesradable esters aqeda ukushisa futhi avikele ukuxabana.
- Ithange: Isitsha esivaliwe esiseduze komgogodla, nomoya kanye namafutha.
- Umesi: I-reservoir inxephezela ukunwetshwa kawoyela / ukuthengiswa ngenxa yezinguquko zokushisa.
- I-Buchholz edluliselwe: Idivaysi yokuphepha ithola amaphutha angaphakathi njengokuqongelelwa kwegesi noma ukuvuza kwamafutha.
Ngesikhathi sokusebenza, ukushintshana kwamanje okuphokomane kwakha i-flux kazibuthe ku-core, kuncenga amandla asemqoka eMvinini Yesibili.
Izici ezibalulekile nezinzuzo
Ama-Oyili Type Power Transformers anikela ngezinzuzo ezihlukile ngaphezu kwezobuchwepheshe obuhlukile:
1. Ukusebenza kahle okupholile okuphezulu
- Ukuvuselelwa okuphezulu okufudumele kwamafutha okufaka amandla kunika amandla ukuncipha kokushisa okusebenzayo, okuvumela abaguqukayo ukuthi baphathe Imithwalo ephakeme
- Ukujikeleza kwamafutha wemvelo (i-thermosiphon umphumela) kunciphisa ukuthembela ezinhlelweni zangaphandle zokupholisa.
2. Kuthuthukiswe amandla dielectric
- I-Transformer Amafutha ihlinzeka ngokufakwa kukagesi okunamandla (ukuhlukaniswa kwamandla kagesi we-30-40 kV / mm), ukuvimbela ukwakheka kwe-arc phakathi kwezinto ezinikezwe amandla.
3. Isikhathi eside sokuphila
- Abaguquli bamafutha abalondolozwe kahle bangasebenza Iminyaka engama-30- 40, ngisho nangaphansi kwemijikelezo eqhubekayo yokulayisha.
- Amafutha anciphisa i-oxidation kanye nokonakaliswa kokufakelwa okusekwe ku-cellulose emandleni.
4. Ukulayisha ngokweqile
- Ingakwazi ukuxhasa ukulayisha ngokweqile kwesikhashana (kuze kufike ku-150% wamandla alinganiselwe) ngaphandle kokuwohloka kokusebenza okubalulekile.
I-5. I-Design enobulungiswa bokulungisa
- Isampula kawoyela ivumela ukulungiswa kokubikezela ngokuhlaziya amagesi ancibilikisiwe (e.g., Methane, i-hydrogen) ukuthola amaphutha ama-insupient.
- I-Sludge kanye nokususwa komswakama ngezinhlelo ze-Filtration zibuyisela izakhiwo zikawoyela.
6. Ukusebenza kwezindleko
- Izindleko eziphansi zokuqala ziqhathaniswa nabaguquli bokwenziwa kokomile kwezicelo eziphakeme ze-voltage (> 33 kv).
- Ukulahleka kwamandla okuncishisiwe (ukusebenza kahle kuze kube yi-99.75%) izindleko eziphansi zokusebenza.
Izicelo embonini kagesi
Ama-oyili wohlobo lwamandla ama-transformers athunyelwa emikhakheni ehlukahlukene:
1. Ukudlulisela Ukufakwa Kwezinto
- I-Step-up Transformers yandisa i-voltage (E.G., 11 KV kuya ku-400 kv) ngokudluliswa kwebanga elide, ukunciphisa ukulahleka komugqa.
2. Izikhungo zezimboni
- Kutholakala ezitshalweni zensimbi, amafektri amakhemikhali, kanye nemisebenzi yezimayini ukuze anciphise ama-grid voltage ngemishini esindayo.
3. Ukuhlanganiswa kwamandla okuvuselelekayo
- Xhuma amapulazi omoya kanye namapaki elanga kuya kumagridi wokuhambisa ngokungena nge-voltage ekhiqizayo (e.g., 0.69 KV ku-132 kv).
4. Ukufakwa kukagesi
- Nikeza amandla esigaba esisodwa ku-25 kV noma ama-50 kV ama-locomotives kagesi.
5. Ukufakwa ngokhetho lwasemakhaya
- I-Step-Down Delivice Transformers (11 KV / 400 v) ukuletha amandla ezindaweni ezikude ngesidingo esishintshashintshayo.

Ukuthathwa Key:
- Abaguquli bamafutha be-Excel ku-High-Voltage, izinhlelo zokusebenza eziphakeme kakhulu kepha zidinga izindlela zokuphepha zomlilo ngokucophelela.
- Abaguquli bohlobo lwe-Dry-Transformers bakhethelwa ukufakwa kwe-Urban ngaphakathi ngenxa yezingozi eziphansi zokuvutha.
