I.Ua rau muaj kev tso tawm ib feem

Lub tshuab hluav taws xob insulator, lub cev hlau thiab lwm yam feem ntau muaj qee lub kaum ntse ntse thiab burr, yog li cov nqi hluav taws xob nyob rau hauv qhov kev ua ntawm lub zog hluav taws xob yuav tsom mus rau lub kaum ntse ntse lossis burr txoj haujlwm thiab ua rau muaj kev tso tawm ib nrab.

Cov epoxy resin insulated qhuav transformer hauv lub tshuab nqus tsev casting, yog tias kev tswj hwm tsis zoo, nws kuj tseem yuav ua rau muaj cov npuas sab hauv thiab tom qab ntawd tsim cov pa tawm ib nrab. Feem ntau muaj qee qhov me me ntawm cov pa hauv epoxy resin insulator, thiab feem ntau cov dielectric coefficient ntawm cov npuas qis dua li cov insulator, yog li ntawd, lub zog hluav taws xob ntawm cov npuas hauv cov insulator siab dua li cov khoom siv insulating uas nyob ib sab, yog li nws yooj yim mus txog qib kev tawg thiab ua rau cov npuas hluav taws xob tawm ua ntej.

Yog tias qhov kev sib txuas hluav taws xob ntawm lub cev conductive tsis zoo, nws yooj yim los tsim hluav taws xob tawm, uas yog qhov loj tshaj plaws hauv cov hlau ncua kev kawm muaj peev xwm.

Cov huab cua noo ntau, lub zog rwb thaiv tsev ntawm ib feem ntawm qhov kev hloov pauv tsis txaus, lossis lub rwb thaiv tsev transformer puas tsuaj thaum lub sijhawm teeb tsa, lub sijhawm tsis ua haujlwm ntawm transformer ntev dhau, cov dej hauv cov khoom rwb thaiv tsev ntau dua li tus qauv, thiab tag nrho lub cev ntawm transformer ntub, uas tseem yuav cuam tshuam rau qhov tso tawm ib nrab.

Thaum tsim cov qauv rwb thaiv tsev qhuav, lub zog ntawm cov khaubncaws sab nraud povtseg lossis cov tig yog siab dhau, xws li kev tsim cov qauv rwb thaiv tsev tsis tsim nyog, cov khoom rwb thaiv tsev tsis zoo, qib ntawm kev sib ntswg, ziab thiab nchuav tsis zoo, qib ntawm kev sib dhos tsis zoo xws li kev tsim cov hlau xaim hluav taws xob siab thiab qis nrog burrs lossis qee qhov deb, txhua yam yuav cuam tshuam rau qhov tso tawm ib nrab kom nce.

II. Qhov Txaus Ntshai ntawm Kev Tso Tawm Ib Nrab

Muaj ntau hom kev tso tawm ib nrab. Ib qho yog ib hom kev tso tawm ib nrab uas tshwm sim ntawm qhov chaw rwb thaiv tsev. Yog tias lub zog loj, qhov kev tso tawm yuav raug cim rau ntawm qhov chaw rwb thaiv tsev thiab yuav cuam tshuam rau lub neej ua haujlwm ntawm lub transformer. Kuj tseem muaj qhov muaj zog tso tawm siab, tshwm sim hauv cavitation lossis electrode ntse, sib sau ua ke hauv ob peb hom kev tso tawm ib nrab yog kev tso tawm corrosive, uas tuaj yeem nkag mus rau hauv cov khaubncaws sab nraud povtseg thiab qhov tob ntawm lub rooj tsavxwm rwb thaiv tsev, thiab thaum kawg ua rau muaj kev tawg.

Kev tso tawm ib feem yog qhov ua rau cov rwb thaiv tsev laus thiab tawg. Lub sijhawm tso tawm luv luv yuav tsis ua rau tag nrho cov channel puas tsuaj, thiab qhov electrolytic action ntawm qhov tso tawm ua rau cov oxidation ntawm rwb thaiv tsev sai dua, thiab corrodes rwb thaiv tsev, yog li lub neej ntawm lub transformer txo qis. Qhov kev puas tsuaj nyob ntawm qhov ua tau zoo ntawm kev tso tawm thiab cov txheej txheem puas tsuaj ntawm rwb thaiv tsev thaum tso tawm. Yog tias qhov kev tso tawm ib feem ntawm lub transformer qhuav dhau nws qib tus qauv, nws lub neej ua haujlwm hauv 3 ~ 5 xyoos sab hauv rwb thaiv tsev laus thiab tawg yuav tshwm sim. Yog li qhov kev tso tawm ib feem ntawm lub transformer qhuav yuav tsum tau tswj hwm nruj me ntsis hauv Suav teb.

III. Kev Tswj Xyuas Ib Feem Ntawm Kev Tso Tawm Transformer Qhuav
Cov khoom siv rwb thaiv tsev tseem ceeb ntawm lub transformer qhuav yog cov khoom siv epoxy resin, muaj kev nyab xeeb thiab txhim khu kev qha, hauv lub zog fais fab qis dua 35kV cov khoom tau siv dav. Muaj ntau yam uas cuam tshuam rau kev tso tawm ib feem ntawm lub transformer qhuav, ntawm cov yam tseem ceeb yog kev xaiv cov khoom siv raw, kev tsim qauv khoom, cov txheej txheem casting winding thiab lwm yam. Vim peb lub tuam txhab tau hloov kho kev tsim qauv mus sij hawm ntev, kev txhim kho cov txheej txheem, kev xaiv cov khoom siv thiab kev xyaum tsim khoom, tau muab cov kev ntsuas tswj hwm hauv qab no.

1. Tsim Qauv Winding
(1) Qhov kev ncua deb ntawm lub rwb thaiv tsev tseem ceeb, thaum tsim cov cua tshuab hloov pauv, yuav tsum xyuas kom meej tias lub kauj hluav taws xob siab thiab qis, ntawm lub kauj hluav taws xob siab, lub kauj hluav taws xob siab mus rau hauv av muaj qhov nrug deb txaus, nyob rau hauv qhov xwm txheej tso cai, qhov deb ntawm lub rwb thaiv tsev loj dua, qhov deb ntawm lub zog teb me dua. Lub rwb thaiv tsev phab ntsa hauv HV kauj tuaj yeem nce ntxiv kom zoo kom txo tau lub zog teb sab nraud.
(2) Tsim cov kauj hluav taws xob siab ntawm cov txheej thiab ntu, uas yog kev tswj hwm lub zog ntawm lub kauj, thiab yog tias HV winding siv cov ntawv ci tooj liab nrog subsection, interlayer voltage sib npaug interturn voltage, feem ntau tsuas yog rau 10 txog 20 v, seem ntawm cov txheej ntawm cov qauv ntawm electromagnetic hlau voltage yog 400 ~ 800v, ​​tus lej seem yuav tsum ntau dua, xws li 35kv qhuav-hom transformer xav tau seem lej ntau dua 16 ~ 18 daim, Tau kawg, nws coj ntau teeb meem rau cov txheej txheem winder.
(3) kev tswj hwm kev tiv thaiv, txais yuav kev tiv thaiv zoo, cov npoo txiav, burrs thiab qhov sib txawv ntawm huab cua tuaj yeem ntim rau hauv lub ntaub thaiv, uas tuaj yeem tshem tawm cov hluav taws xob tawm ntawm qhov tawg, thiab txo qhov tawm ib nrab. HV ntaub thaiv thiab HV xaim kawg, LV thiab clamp yuav tsum muaj kev sib txuas txhim khu kev qha, kev ua haujlwm tiv thaiv yuav tsum khaws cia kom huv, cov txheej tiv thaiv yuav tsum du, tsis muaj tawg thiab taub hau, thiab lwm yam.

2. Coil winding, Molding thiab Vacuum Pouring Process Control

Qhov tseem ceeb tshaj plaws rau kev siv transformer yog qhov zoo lossis tsis zoo yog tias lub kauj puas lawm. Qhov cuam tshuam ntawm kev nchuav lub tshuab nqus tsev kuj tseem ceeb heev rau qhov tso tawm hauv zos, txawm tias cov qhov me me kuj cuam tshuam rau qhov tso tawm hauv zos ntawm lub transformer, yog li cov txheej txheem tsim khoom thiab casting ntawm lub kauj yuav tsum tau tswj hwm nruj me ntsis.

(1) thaum lub kauj vuam, peb yuav tsum paub txog cov duab kos thiab cov txheej txheem, thiab tsis tuaj yeem hloov pauv tus naj npawb ntawm kev tig ntawm cov khaubncaws sab nraud povtseg thiab tus naj npawb ntawm cov ntawv rwb thaiv tsev ntawm cov khaubncaws sab nraud povtseg! Xyuas kom tseeb tias txhua yam khoom siv huv si thaum lub sijhawm vuam.

(2) Thaum txhim kho pwm txhuas qhov chaw vuam, xyuam xim rau qhov kub siab ua rau lub kauj rwb thaiv tsev puas tsuaj, cov hlau vuam yuav tsum tau txhuam kom ntse ces kaum, thiab lwm yam. Xyuas kom tseeb tias txhua lub hlau raug rwb thaiv tsev ntawm qhov deb txaus kom puv nrog epoxy resin thiab ntxuav thoob plaws hauv cov txheej txheem sib dhos. Lub kauj tuag uas tau teeb tsa raug ziab kom nruj raws li cov txheej txheem ziab.

(3) cov khoom xyaw epoxy resin thiab degassing, cov txheej txheem batching yuav tsum ua raws li cov cai siv tshuab, xws li cov khoom siv, qhov sib tov sib piv, qhov kub thiab lub sijhawm degassing, qhov viscosity ntawm qib yuav tsum taug qab ze rau qhov sib xws, qib nqus tsev, qhov kub thiab npuas dej tshwm sim, sib tov, qhov kub thiab npuas dej ua kom lub kauj soj ntsuam (pwm) nyob rau hauv qhov ntau thiab tsawg ntawm kev tswj qhov kub hauv cov txheej txheem teev tseg. Hauv cov txheej txheem pouring, qhov ceev yuav tsum tsis txhob ceev dhau thiab tsim cov npuas dej. Thaum dynamic pouring, yuav tsum tau them sai sai rau lub sijhawm tom qab cov khoom xyaw tiav pouring kom tiv thaiv cov resin viscosity loj dhau.

3. Kev xaiv thiab kev tswj cov khoom siv raw

(1) Kev xaiv cov hlau electromagnetic, tuaj yeem xaiv cov hlau enameled rwb thaiv tsev tiaj tus tooj liab lossis puag ncig tooj liab hlau tsim winding; Cov neeg xa khoom hlau electromagnetic hauv kev tsim khoom, yuav tsum muaj cov khoom siv deburring tshwj xeeb thiab cov khoom siv kuaj pom, thiab siv zog kom txo cov burrs kom tsawg kawg nkaus.

(2) kev xaiv cov ntaub ntawv epoxy resin, epoxy resin sib txawv, nws cov yam ntxwv sib txawv, qhov kev tso tawm hauv zos ntawm cov khoom, qhov kev ua tau zoo ntawm qhov cuam tshuam kuj zoo heev, yuav tsum xaiv cov viscosity me me, toughness zoo, lub zog rwb thaiv tsev siab ntawm cov resin, cov qauv resin sib txawv, lub chaw haujlwm kev tshaj lij los tsim cov txheej txheem sib xws.

(3) kev tswj cov khoom siv rwb thaiv tsev hauv lub kauj, qhov zoo ntawm cov khoom siv rwb thaiv tsev ntawm cov txheej ntawm cov transformer qhuav yog ncaj qha cuam tshuam rau qhov loj ntawm cov khoom hauv zos. Yog li ntawd, cov neeg xa khoom mus sij hawm ntev thiab ruaj khov yuav tsum tau xaiv los muab cov khoom siv raw, vim tias tom qab hloov cov khoom tshiab, lub transformer tsis tuaj yeem pom teeb meem hauv lub sijhawm luv luv.
