kutheni i-VPD ibaluleke kangaka kwimveliso ye-power transformer kwaye ngoobani ababoneleli abaphambili eTshayina
Ukomisa iVapor Phase (VPD) yenye yezona nkqubo zibalulekileyo ekwenzeni iitransformer zamandla kuba iqinisekisa ukususwa ngokupheleleyo komswakama kwinkqubo yokukhusela (ngokuyintloko iphepha le-cellulose kunye nebhodi yokucinezela). Ukufuma yenye yezona ntshaba zinkulu zokuthembeka kweetransformer.
Nazi izizathu eziphambili zokuba kutheni i-VPD ibaluleke kangaka:
- Ukufuma Kunciphisa Kakhulu Amandla Okugquma
Iinkqubo zokufakelwa kwe-transformer zenziwe ikakhulu ngezinto ze-cellulose (iphepha, ibhodi yokucinezela) ezidityaniswe neoyile ye-transformer.
- Nokuba yi-1–2% yokufuma kwi-cellulose kunokunciphisa kakhulu amandla e-dielectric.
- Amanzi anokubangela ukukhupha okungaphelelanga, ukungasebenzi kakuhle kobushushu, kunye neempazamo zangaphakathi.
I-VPD inciphisa umxholo wokufuma kwi-insulation ube ngaphantsi kwe-0.5%, nto leyo efunekayo kwii-transformers ezine-voltage ephezulu kunye ne-extra-high-voltage.
- Yandisa Ubomi Bokuguqula
Ukufuma kukhawulezisa ukuguga kwe-cellulose nge-hydrolysis.
Iziphumo zokufuma:
- Ukonakala kwetyathanga lepolymer ngokukhawuleza
- Iqondo elinciphileyo le-polymerization (DP)
- Ubomi bomguquli obufutshane
Ukomisa kakuhle nge-VPD kunokwandisa ubomi be-transformer ukusuka kwiminyaka engama-20 ukuya kwiminyaka engama-40 nangaphezulu kwiimeko ezininzi.
- Ikhawuleza Kakhulu Kunokomisa Nge-Vacuum Eqhelekileyo
Ukomisa umoya oshushu wendabuko okanye i-vacuum kuhamba kancinci kuba ukudluliselwa kobushushu ngaphakathi kokujija akusebenzanga kakuhle.
I-VPD isebenzisa isinyibilikisi esinomphunga (ngesiqhelo i-kerosene) esi:
- Ii-condens kumphezulu we-insulation obandayo
- Ikhupha ubushushu obukhulu obufihlakeleyo
- Ingena nzulu kwindawo ejikelezayo
Isiphumo:
- Ukufudumeza okufanayo
- Ukomisa ngokukhawuleza kakhulu
Uthelekiso lwexesha oluqhelekileyo:
Indlela Yokomisa Ixesha Eliqhelekileyo
Ukomisa umoya oshushu iintsuku ezili-10--20
Ukomisa nge-vacuum iintsuku ezi-5--10
I-VPD iintsuku ezi-2--5
- Ukomisa nzulu izakhiwo zokukhusela ezixineneyo
Iitransformer ezinkulu zamandla zinezakhiwo zokukhusela ezixineneyo kakhulu:
- Iisilinda zebhodi yokucinezela ezixineneyo
- Iiwindings ezineeleya ezininzi
- Iindibano ezinkulu ze-core-coil
I-VPD ibonelela ngobushushu obungena nzulu, ivumela umswakama ukuba uphume kwiileya zangaphakathi zokukhusela, nto leyo enzima ngezinye iindlela zokomisa.
- Kubalulekile kwiiTransformers zeVoltage ephezulu
Kwi-transformers eziyi-≥220 kV, ingakumbi i-400 kV / 500 kV / 765 kV, i-VPD ithathwa njengezixhobo ezisemgangathweni kushishino.
Uninzi lwabavelisi abakhulu bayisebenzisa, njengale:
- Amandla eSiemens
- Amandla eHitachi
- GE Vernova
- I-TBEA
Ngaphandle kokomiswa ngokufanelekileyo, i-transformer ayinakudlula kwi-implication kwaye i-AC iyakwazi ukumelana novavanyo.
- Iphucula ukusebenza kakuhle kwemveliso
Iinkqubo ze-VPD zikwaphucula ukusebenza kakuhle kwemveliso:
- Umjikelo wemveliso omfutshane
- Umgangatho wobushushu ohambelanayo ngakumbi
- Umngcipheko ophantsi wokungaphumeleli kovavanyo lwasefektri
Kwimizi-mveliso evelisa ii-transformer ezinkulu zamandla, i-VPD idla ngokuba yingxaki yemveliso, ngoko ke ukuthembeka kwayo kunye nomthamo wayo kubalulekile.
Ngamagama alula:
Ukuba ukujija "yintliziyo" yetransformer, ukoma kwe-insulation "bubomi" bayo.
I-VPD yeyona ndlela isebenzayo yokuqinisekisa ubomi.
Ekubeni ukhankanyile ngaphambili ukuba usebenza kwiithenda zezixhobo ze-transformer kwiiprojekthi ze-Siemens, izixhobo ze-VPD zihlala ziphakathi kwezona matshini zixabisekileyo kakhulu kwaye zivavanywa kakhulu ngobuchwephesha kutyalo-mali lwefektri ye-transformer.
Ukuba ungathanda, ndingachaza:
- Kutheni iifektri ezininzi ze-transformer zikhetha i-VPD kune-Hot Oil Spray (HOS)
- Iiparameter eziphambili zobugcisa ezivavanywa ngabathengi xa bebhida iinkqubo ze-VPD
- Zeziphi iinkampani ezilawula imarike yezixhobo zeVPD kwihlabathi liphela
Ezi ngongoma zihlala zibaluleke kakhulu kwiithenda zezixhobo ze-transformer.
Kwishishini le-power transformer, imakethi yezixhobo zeVapor Phase Drying (VPD) incinci kwaye ikhethekile, ngenani elilinganiselweyo lababoneleli abanamava kwihlabathi liphela. Abavelisi be-transformer badla ngokukhetha ababoneleli abaneereferensi ezinde kunye nobuchwepheshe bokomisa obuvunyiweyo, kuba i-VPD ibalulekile kumgangatho wobushushu.
Apha ngezantsi kukho umbono osebenzayo weshishini ngababoneleli abaphambili.
