Qhuav Hom Epoxy Resin Cast Transformer Structure
1. Hlau Core
1.1 Core qauv. Cov tub ntxhais hlau ntawm lub tshuab ziab khaub ncaws qhuav yog qhov sib nqus ntawm qhov sib nqus, uas muaj cov hlau core kem thiab ib tug quab hlau. Cov windings yog qhwv ib ncig ntawm lub hauv paus ob txhais ceg, thiab tus quab yog siv los kaw tag nrho cov hlau nplaum Circuit Court. Cov qauv ntawm cov tub ntxhais hlau feem ntau muab faib ua ob hom: core hom thiab plhaub hom. Cov tub ntxhais-hom core yog tus cwj pwm nyob rau hauv hais tias lub yoke hlau nyob rau sab saum toj thiab hauv qab qhov chaw ntawm lub winding, tab sis tsis nyob ib ncig ntawm ob sab ntawm winding; lub plhaub-hom core yog tus cwj pwm nyob rau hauv hais tias lub yoke hlau tsis tsuas yog nyob ib ncig ntawm lub sab saum toj thiab hauv qab qhov chaw ntawm lub winding, tab sis kuj nyob ib ncig ntawm lub sab ntawm winding. Vim hais tias cov tub ntxhais-hom hlau core qauv yog yooj yim, kev npaj thiab rwb thaiv tsev ntawm cov windings kuj yog ib qho yooj yim, yog li cov tub ntxhais-hom hlau core feem ntau yog siv nyob rau hauv lub hwj chim qhuav-hom transformers nyob rau hauv kuv lub teb chaws, thiab lub plhaub-hom hlau. core tsuas yog siv nyob rau hauv qee qhov tshwj xeeb qhuav-hom transformers (xws li hluav taws xob rauv qhuav-hom transformers).
1.2 Cov khoom siv tseem ceeb. Txij li cov tub ntxhais hlau yog qhov sib nqus ntawm lub tshuab ziab khaub ncaws, nws cov khoom yuav tsum tau zoo sib nqus permeability. Tsuas yog nrog zoo sib nqus permeability tuaj yeem ua rau cov hlau poob me me. Yog li ntawd, cov tub ntxhais hlau ntawm qhov qhuav-hom transformer yog ua los ntawm silicon steel los xij. Muaj ob hom silicon steel los xij: kub dov thiab txias dov. Txij li cov ntawv txias-dov silicon steel ntawv muaj qhov sib nqus permeability ntau dua thiab cov chav me me poob thaum sib nqus raws cov kev taw qhia dov, nws cov kev ua tau zoo dua li ntawm cov kub-dov. Cov tshuab ziab khaub ncaws hauv tsev txhua tus siv cov ntawv txias-kuav los tiag silicon steel ntawv. Lub thickness ntawm domestic txias-dov silicon steel ntawv yog 0.35, 0.30, 0.27mm thiab hais txog. Cov ntawv tuab dua, qhov loj dua qhov poob tam sim no, thiab cov ntawv nyias nyias, qhov me me ntawm cov lamination, vim tias cov ntawv ntawm silicon steel yuav tsum tau coated nrog ib txheej ntawm insulating kua roj vanish kom insulate cov nplooj ntawv.
2. Cua
Lub winding yog ib feem ntawm lub tshuab ziab khaub ncaws qhuav, uas feem ntau yog ua los ntawm insulating enameled, ntawv qhwv aluminium hlau los yog tooj liab hlau.
Raws li kev sib txawv ntawm qhov siab thiab qis voltage windings, cov windings tau muab faib ua ob hom: concentric thiab pob zeb diamond-stacked. Rau concentric windings, txhawm rau pab txhawb kev rwb thaiv tsev ntawm cov cua ntsawj ntshab thiab cov tub ntxhais, qhov qis-voltage winding feem ntau yog muab tso rau ze ntawm cov tub ntxhais kem; rau lub overlapped winding, thiaj li yuav txo tau qhov kev ncua deb ntawm rwb thaiv tsev, qhov tsawg-voltage winding feem ntau yog muab tso rau ze rau cov hlau yoke.
3. rwb thaiv tsev
Lub ntsiab insulating cov ntaub ntawv nyob rau hauv lub qhuav-hom transformer yog qhuav-hom transformer roj, insulating cardboard, cable ntawv, crepe ntawv, thiab lwm yam.
4. Coj mus rhaub changer
Txhawm rau muab qhov hluav taws xob ruaj khov, tswj lub zog ntws los yog kho cov khoom thauj tam sim no, lub tshuab ziab khaub ncaws qhuav yuav tsum tau kho rau qhov hluav taws xob. Tam sim no, txoj kev kho qhov hluav taws xob ntawm lub tshuab ziab khaub ncaws qhuav yog los teeb tsa tus kais ntawm ib qho ntawm nws cov windings los txiav lossis ntxiv ib feem ntawm cov lem ntawm winding los hloov cov lej ntawm cov winding, thiaj li. ua tiav ib kauj ruam-rau-kauj ruam hloov txoj kev uas hloov qhov voltage piv. . Lub Circuit Court nyob rau hauv uas no winding yog tapping rau voltage tswj yog hu ua voltage regulating circuit; qhov hloov pauv siv rau kev hloov pauv thiab tapping rau kev tswj hluav taws xob yog hu ua kais hloov pauv. Feem ntau, qhov tsim nyog kais yog kos rau ntawm qhov siab voltage winding. Qhov no yog vim lub high-voltage winding feem ntau sheathed sab nraum, uas yog yooj yim rau coj tawm thiab kais. Tsis tas li ntawd, qhov tam sim no nyob rau sab high-voltage yog me me, qhov cross-section ntawm tus kais dej thiab cov khoom nqa tam sim no ntawm tus kais hloov pauv me me, thiab qhov kev sib cuag ntawm lub tshuab hluav taws xob kuj yooj yim dua rau kev tsim khoom.
Cov kev cai voltage nyob rau hauv lub thib ob sab ntawm lub qhuav-hom transformer tsis muaj load thiab thawj sab tseem yog disconnected los ntawm daim phiaj (tsis muaj fais fab mov excitation) yog hu ua non-excitation voltage regulation, thiab cov voltage tswj nyob rau hauv lub transformer winding. taps nrog load yog hu ua on-load voltage regulation.
5. Cov roj tank
Cov roj tank yog lub plhaub sab nraud ntawm lub tshuab ziab khaub ncaws qhuav, lub cev qhuav-hom hloov pauv tau muab tso rau hauv cov roj tank, thiab lub tank ntim nrog cov roj qhuav-hom transformer. Raws li qhov loj ntawm qhov qhuav-hom transformer, cov qauv roj tank tau muab faib ua ob hom: hanger lub cev roj tank thiab dai lub thawv plhaub roj tank.
(1) Lifter lub cev hom roj tank. Nws feem ntau yog siv rau qhuav-hom transformers ntawm 6300kVA thiab hauv qab no. Lub thawv ntug yog teem rau saum thiab lub thawv npog yog tiaj tus. Vim yog lub peev xwm me me ntawm cov tshuab ziab khaub ncaws qhuav, qhov hnyav yog lub teeb, thiab lub cev yog qhov yooj yim rau kev nqa thaum tu.
(2) Hanging box plhaub hom roj tank. Nws feem ntau yog siv rau qhuav-hom transformers ntawm 8000kVA thiab siab dua. Lub tank ntug yog nyob rau hauv qis qis, thiab sab sauv ntawm lub tank lub cev yog ua los ntawm hood, yog li nws tseem hu ua lub tswb-hom roj tank. Tsis muaj qhov xav tau rau lub cev hanger thaum lub sijhawm tu, tsuas yog lub thawv lub cev tuaj yeem nqa tau.
