Lub tshuab nqus tsev siab impregnation
1. Txhim kho kev ya raws cov kab ntawm ib ncig ntawm cov pab pawg
Txij li cov pores ntawm capillary raug txo qis, qhov saum npoo tau tsim rau hauv zaj duab xis ntom thiab du xim, thiab nws yog qhov nyuaj rau dej rau sab hauv sab hauv ntawm txheej txheej insulating, yog li cov dej noo kom zoo dua qhov cuam tshuam. Piv txwv li, E-chav tsev tiv thaiv lub cev muaj zog me uas tsis muaj cov kua roj vanish tau ntub (qhov txheeb ze li cua sov 95% -98%) (48h, lub rwb thaiv tsis kam poob los ntawm 40MΩ txog 0.2MΩ, thaum VPI-kho lub cev muaj zog, nyob rau hauv tib qho kev mob , Qhov rwb thaiv tsev tseem nyob saum 16MΩ.
2. Txhim kho qhov hluav taws xob ua rau ntawm winding
Cov khoom hluav taws xob muaj zog ntawm insulating varnishes muaj ntau yam zoo dua li huab cua. Piv txwv li, cov xim 1032 muaj lub zog tawg ntawm 70 txog 90 kV / hli hauv cov kev mob ib txwm, thiab lub zog tawg ntawm huab cua hauv cov txheej txheem cov qauv tsuas yog 33 kV / hli. Tom qab ua tiav VPI, cov kab hlau tau sib koom ua ke thiab cov huab cua hauv cov txheej txheej insulating yog tshem tawm, yog li ua kom pib pib qhov pib hluav taws xob dawb thiab lwm yam khoom siv hluav taws xob ntawm qhov winding.
3. Txhim kho cov cua sov thiab cov thermal conductivity ntawm winding
Tom qab kev kho cov rwb thaiv tsev, kev tiv thaiv tshav kub ntawm cov organic ua kom muaj zog tau nce los ntawm Y txog Qib A. Cov thermal conductivity ntawm cov kua roj insulating qhuav yog 0.14 ~ 0.6W / (m · ° C (lub epoxy nplaum yog 0.2-0.5W / (m · ° C (thiab cov thermal conductivity ntawm huab cua yog 0.025 ～ 0.03W / (m ·) ° C (, tom qab VPI kev kho mob, qhov tseem ceeb, zawj thiab sab hauv tsis muaj cua ntawm cov cua tau muaj cov xim pleev xim, uas txhim kho lub thermal conductivity ntawm lub winding.
4. Txhim kho cov khoom siv ntawm cov winding
Tom qab kev kho mob ntawm VPI, cov xaim xaim xaim tau sib koom ua ke tag nrho, yog li txhim kho qhov plam thiab hnav ntawm kev rwb thaiv tsev vim kev vibration, lub zog ntawm cov hluav taws xob thiab cov thermal ua kom loj thiab muaj kev sib txuam.
5. Txhim kho qhov ruaj khov tshuaj ntawm cov winding
Tom qab kev kho VPI, cov xim pleev xim tuaj yeem tiv thaiv cov khoom insulating los ntawm kev sib cuag ncaj qha rau cov tshuaj lom neeg nruab nrab thiab ua rau lub rwb thaiv tsev ua haujlwm. Lub kiav txhab no tseem tuaj yeem ua tus ntxig tiv thaiv kom tsis txhob muaj cov corona thiab roj.
