V. Unveiling VPI cov txheej txheem: kos duab ntawm kev tsim khoom hauv cov kauj ruam ruaj khov
VPI cov txheej txheem yog deb ntawm qhov yooj yim "soaking"; Nws yog lub cev lub cev ua tiav raws li kev tswj hwm meej, feem ntau yog cov kauj ruam hauv qab no:
1. Ua ntej - ci thiab ua kom qhuav: Ua ntej, cov kev sib sau ua ke Transformer tau muab tso rau hauv qhov cub thiab ci rau lub sijhawm ntev nyob rau hauv cov chaw nqus dej thiab cua sov. Lub hom phiaj ntawm cov kauj ruam no yog kom ua kom tiav tag nrho cov dej noo thiab cov ntaub ntawv tsis sib xws (xws li cov ntaub ntawv, zaj duab xis) thiab hauv qhov khoob ntawm cov imprings, npaj rau cov impregnation tom ntej.
2. Nqus tsev impregnation: Cov kev hnav qhuav huv si tau hloov mus rau ib qho loj, sealable vpi kho mob. Tom qab ntawd, lub tshuab nqus hluav taws xob haib yog ua kom tiav los kos lub tank rau lub xeev siab nqus. Nyob rau hauv lub tshuab nqus tsev siab, noo noo noo nyob sab hauv lub tshuab windings sab hauv lub micro- qhov tsis zoo rau kev nkag mus tom qab ntawm insuling vanish.
3. Painting thiab Pressurization: Tom qab tswj lub tshuab nqus tsev lossis tso nws cov xim uas tau ua ntej epioxy eplicone lossis silicone resin lossis silicone resin) uas tau ua tiav rau hauv lub tank kom txog thaum nws ua tiav cov windergle. Tom qab ntawd los cov tub ntxhais tseem ceeb ntawm cov txheej txheem- thov ob peb lub tshuab cua ntawm lub siab (xws li 6 atmospheres) rau lub tank. Qhov kev siab siab no rog cov xim insulating kom raug nias rau hauv thiab sau txhua tus me nyuam me me uas tau nyob nrog cua, ua tiav tob thiab meej impregnation.
4. Sim thiab kho: Tom qab tus impregnation tiav lawm, cov kua roj ntau dhau, thiab cov windings tau tawm thiab rub tawm nrog cov kua roj vanish kom ntseeg tau tias ib qho chaw zoo. Thaum kawg, cov windings raug xa mus rau hauv kev kho qhov cub thiab rhaub kom sov raws li qhov ntsuas kub nruj raws li kub- lub sijhawm nkhaus. Thaum lub sijhawm cov txheej txheem no, lub insulating varnish undergish txawv, hloov los ntawm cov kua rau lub xeev muaj zog, thiab kho kom tau tag nrho cov pob zeb rau hauv lub pob zeb {}}} cov khoom insulating.
VI. Qhov Zoo Ntawm VPI Transformers
Lub tshuab nqus tsev siab impregnation (vpi) cov txheej txheem Nws cov ntsiab lus zoo tuaj yeem ua tau teev hauv qab cov ntsiab lus hauv qab no:
1. Cov Hluav Taws Xob Hluav Taws Xob Rwb Thaiv Tsev
Cov txheej txheem VPI insces resulating resulating resin rau txhua lub tshuab tsom me me tsis pub dhau lub tshuab winding hauv qab nqus thiab siab. Qhov no tshem tawm cov hauv paus cag tsim tawm ntawm lub zog sab hauv, tso cai rau lub neej ntawm lub neej kev ntxhov siab thiab ntau yam kev cuam tshuam ntau dua impulses.
2. Tshwj xeeb ib puag ncig tsis kam thiab tiv thaiv
Cov txheej txheem tsim cov txheej txheem tuab, ua kom tiav resin encapsulation txheej uas muaj zoo thaiv noo noo, cov tshuaj ntsev, cov tshuaj nplaum, thiab pwm. Qhov no ua rau VPI transformers tshwj xeeb haum rau cov av noo ib puag ncig, xws li cov nroj tsuag cua, tshuaj ntsuab, qhov chaw uas lawv tau ua rau muaj kev ruaj khov zoo.
3. Txhim Kho Thermal Kev tswj thiab kub dissipation
Lub thermal conductivity ntawm impregnating resin yog farior zoo dua rau cov cua nws hloov. Los ntawm sau cov voids, lub resin tsim cov cua txias tshaj cov cua sov sab hauv, tso cai ua cua sov kom tau pauv ntau yam rau sab nraud txias chaw. Qhov no tsis yog txo qis kev ua haujlwm kub tab sis kuj ua rau muaj peev xwm thauj khoom siab lossis tsim kev cog lus ntau dua.
4. Cov qauv muaj zog thiab cov lus luv-} Circuit Court wittst lub peev xwm
Tom qab Impregnation thiab kho, cov windings, insulating cov ntaub ntawv, thiab cov khoom yog solidified rau hauv ib qho, tawv tawv. Cov qauv no muab cov cua tshuab hluav taws xob muaj zog, ua rau muaj kev co electromagnet, yog li siv cov khoom siv hluav taws xob ntau ntxiv thiab ua kom luv {{sib zog.
5. Txuas ntxiv txoj kev pabcuam lub neej thiab kev ntseeg siab
Los ntawm kev sib txuas ua ke zoo hluav taws xob, tshuab, thiab anti -}}}} Cov txheej txheem laus, cov kev laus yog maj mam ua qeeb. Qhov no ncaj qha txhais ua kev tsim kho ntev dua, cov kev ua haujlwm qis dua, thiab kev txhawb siab ntau dua, piv txwv li, cov ntaub ntawv chaw, tsheb thauj mus los).
6. Optimized tag nrho cov nqi ntawm cov tswv cuab (TCO)
Txawm hais tias tus nqi pib tsim nyog ntawm VPI transformer tej zaum yuav muaj kev ntseeg siab dua, nws txoj kev hloov kho, thiab hloov pauv ntawm tag nrho cov kev pabcuam tag nrho. Nyob rau hauv lub sijhawm ntev, nws txoj haujlwm ua haujlwm ntau dua thiab kev saib xyuas tsawg kawg nkaus hauv kev ua haujlwm ntau dua ntawm cov tswv cuab.
