Advanced drying method for dry-type transformers: induction cua sov thiab cua kub kom qhuav

Cov tshuab ziab khaub ncaws qhuav yog ib qho tseem ceeb hauv ntau lub tshuab hluav taws xob, muab cov rwb thaiv tsev zoo tshaj plaws thiab kev nyab xeeb piv rau cov khoom siv roj-immersed. Txawm li cas los xij, txhawm rau txhawm rau ua kom zoo tshaj plaws thiab ua haujlwm ntev, kev ziab kom zoo thaum tsim khoom yog qhov tseem ceeb. Hauv qhov blog no, peb yuav tshawb txog ob txoj hauv kev kom qhuav qhuav-hom transformers: induction cua sov thiab cua kub kom qhuav. Cov txheej txheem no tau lees paub qhov kev tshem tawm ntawm cov dej noo, xyuas kom muaj kev ruaj ntseg thiab ua raws li VI) E0550, IEC 439, JB 5555, GB5226 thiab lwm yam qauv thoob ntiaj teb.

1. Induction cua sov txoj kev:

Txoj kev siv cua sov induction yog siv cov cua sov uas tsim los ntawm qhov poob tam sim no hauv lub tank phab ntsa kom ua tiav lub hom phiaj ntawm ziab. Cov txheej txheem yuav tsum muab lub cev tseem ceeb ntawm cov cuab yeej nyob rau hauv lub tank thiab dhau lub zog zaus tam sim no los ntawm cov txheej winding coil. Nov yog qee cov ntsiab lus tseem ceeb ntawm txoj kev:

- Kev Tswj Kub: Txhawm rau tiv thaiv kev puas tsuaj rau lub tshuab hloov pauv, nws yog ib qho tseem ceeb kom tswj tau qhov kub thiab txias. Qhov kub ntawm lub thawv phab ntsa yuav tsum tsis txhob siab tshaj 115-120 ° C, thiab qhov kub ntawm lub thawv yuav tsum khaws cia ntawm 90-95 ° C.

- Coil Winding: Rau qhov yooj yim ntawm coil winding, nws raug nquahu kom siv tsawg dua los yog qis dua tam sim no. Ib qho tam sim no ntawm ib ncig ntawm 150A yog qhov tsim nyog thiab siv cov hlau loj ntawm 35-50mm2. Tsis tas li ntawd, muab ntau cov asbestos strips rau ntawm phab ntsa ntawm cov roj tank yog qhov zoo rau kev sib tw ntawm cov xov hlau.

2. Cov cua kub kom qhuav txoj kev:

Cov cua kub kom qhuav yog muab lub cev qhuav-hom transformer rau hauv chav tswj kom qhuav kom qhuav cua kub. Xav txog cov ntsiab lus hauv qab no rau txoj hauv kev no:

- Kev tswj ntsuas kub: Thaum siv cov cua kub, nws yog ib qho tseem ceeb kom maj mam nce qhov kub ntawm qhov nkag thiab xyuas kom tsis pub dhau 95 ° C. Txoj kev tswj hwm no tso cai rau kom qhuav kom ntseeg tau yam tsis muaj kev phom sij.

- Cua Lim: Txhim kho lub lim ntawm cov cua kub nkag yog qhov tseem ceeb los tiv thaiv cov pa taws thiab plua plav nkag mus rau hauv chav ziab. Cov kauj ruam pom no ua kom ib puag ncig huv thiab nyab xeeb.

Txhawm rau kom tau txais cov cua kub kom qhuav, tsis txhob tshuab cua kub ncaj qha mus rau lub cev tseem ceeb ntawm cov khoom siv. Hloov chaw, cov cua ntws yuav tsum tau muab sib npaug ntawm txhua qhov kev qhia los ntawm hauv qab, tso cai rau cov dej noo kom dim ntawm cov vents hauv lub hau.

Hauv kev xaus:

Cov tshuab ziab khaub ncaws qhuav yuav tsum tau ziab kom zoo kom tshem tawm cov dej noo, ua kom zoo tshaj plaws thiab ua raws li cov qauv thoob ntiaj teb. Los ntawm kev siv cov kev tshaj lij xws li induction cua sov thiab cua kub kom qhuav, cov tuam ntxhab tuaj yeem lav qhov kev lag luam txhim khu kev qha thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob tseem ceeb no. Ob txoj hauv kev muaj qhov zoo meej, thiab lawv qhov kev siv yog nyob ntawm cov kev xav tau tshwj xeeb thiab muaj peev xwm tsim khoom. Nrog rau kev ziab kom zoo, cov tshuab ziab khaub ncaws qhuav yuav txuas ntxiv muab cov rwb thaiv tsev zoo thiab ua tau raws li cov kev xav tau ntawm cov tshuab hluav taws xob niaj hnub no.

(Ceeb Toom: Qhov blog no muab cov lus qhia txog kev ziab ntawm cov tshuab ziab khaub ncaws qhuav thiab qhia txog lawv qhov tseem ceeb. Rau kev qhia thiab cov lus qhia tshwj xeeb, nws raug nquahu kom sab laj cov kws tshaj lij kev lag luam thiab ua raws li cov qauv thiab cov kev cai.)
