Ntawm cov khoom tseem ceeb ntawm lub transformer, lub winding ua hauj lwm ua "conduction center" rau hluav taws xob hloov dua siab tshiab. Nws cov txheej txheem zoo ncaj qha txiav txim siab qhov ruaj khov thiab kev ntseeg siab ntawm cov cuab yeej siv thaum lub sijhawm ua haujlwm ntev -. Txawm hais tias nws yog ib qho kev lag luam hluav taws xob faib hluav taws xob lossis lub zog tshiab-tshwj xeeb transformer, yog tias winding muaj cov txheej txheem tsis xws luag, nws yuav ua rau muaj teeb meem me me xws li kev kub ntxhov hauv zos thiab nce kev poob, lossis txawm tias muaj kev puas tsuaj loj xws li rwb thaiv tsev tawg thiab kub hnyiab, ua rau muaj kev lag luam loj. Cov kab lus no yuav pib los ntawm cov kev sib txuas tseem ceeb ntawm cov txheej txheem winding, txheeb xyuas nws hauv - qhov tob cuam tshuam rau kev ruaj ntseg transformer, thiab muab cov ntaub ntawv rau kev xaiv kev lag luam thiab kev tsim kho kom zoo.
I. Lub luag haujlwm tseem ceeb ntawm Cov Txheej Txheem Cuab Yeej: "Cov Kab Tseem Ceeb ntawm Kev Tiv Thaiv" rau kev ruaj ntseg
Lub tshuab hluav taws xob winding yog tsim los ntawm cov xov hlau winding, feem ntau ua haujlwm ntawm ob lub zog ntawm "electromagnetic induction" thiab "tam sim no kis tau tus mob". Thaum lub sij hawm ua haujlwm, lub winding yuav tsum tiv taus peb hom kev ntxhov siab: hluav taws xob kev nyuab siab, thermal stress, thiab mechanical stress. Kev ntxhov siab hluav taws xob yog los ntawm cov hluav taws xob hauv hluav taws xob hauv qhov hluav taws xob siab, kev ntxhov siab thermal tshwm sim los ntawm cov cua sov uas tshwm sim los ntawm kev poob tam sim no, thiab cov neeg kho tshuab kev ntxhov siab yog tshwm sim los ntawm cov hluav taws xob hluav taws xob vim yog luv luv -circuit tam sim no. Los ntawm kev sib txuas xws li kev xaiv cov hlau, winding precision, thiab kev kho rwb thaiv tsev, cov txheej txheem winding ncaj qha txiav txim siab lub peev xwm los tiv thaiv peb hom kev ntxhov siab, ua haujlwm raws li "cov kab hauv paus ntawm kev tiv thaiv" rau kev ua haujlwm ruaj khov transformer.
Raws li kev lag luam txhaum kev txheeb cais, kwv yees li 35% ntawm kev hloov pauv tam sim ntawd cuam tshuam nrog cov txheej txheem winding, ntawm cov "ib feem tawm los ntawm xoob winding" thiab "tig- rau-tig luv luv Circuit Court tshwm sim los ntawm cov txheej txheem rwb thaiv tsev puas tsuaj" rau feem ntau tshaj plaws. Cov ntaub ntawv no tau lees paub ntxiv tias qhov ua tau zoo - cov txheej txheem winding zoo tsis yog qhov yuav tsum tau ua ua ntej rau kev ua raws li cov khoom lag luam tab sis kuj tseem yog qhov tseem ceeb lav rau lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov khoom siv.
II. Kev cuam tshuam tshwj xeeb ntawm cov txheej txheem tseem ceeb txuas rau kev ruaj ntseg
Cov txheej txheem winding npog plaub qhov txuas: hlau xaiv, txoj kev winding, kev kho rwb thaiv tsev, thiab ziab & kho. Cov ntsiab lus ntawm txhua qhov txuas yog ze ze rau kev ruaj ntseg transformer, nrog rau cov kev cuam tshuam tshwj xeeb raws li hauv qab no:
1. Kev xaiv hlau: Tswj kev poob thiab cua sov ua haujlwm los ntawm "Qhov Chaw".
Raws li "lub hauv paus" ntawm winding, cov khoom siv, specification, thiab kev kho saum npoo ntawm cov hlau ncaj qha cuam tshuam rau cov conductive efficiency thiab thermal stability ntawm winding:
- Kev xaiv khoom siv:Tam sim no, lub ntsiab winding hlau yog tooj liab xov hlau thiab txhuas hlau. Lub conductivity ntawm tooj liab hlau yog kwv yees li 30% siab dua li ntawm txhuas hlau. Nyob rau hauv tib lub load, tooj liab windings muaj qis dua, tsawg tshav kub tiam, qeeb thermal aging thaum lub sij hawm ntev - ua hauj lwm, thiab tseem ceeb stability zoo. Txawm hais tias cov xov hlau txhuas muaj cov nqi qis dua, lawv yuav tsum muaj tus ntoo khaub lig loj dua - ntu ntu kom phim qhov kev ua tau zoo ntawm cov xov hlau tooj liab, uas yooj yim ua rau muaj qhov nce hauv qhov ntim thiab cov cua kub ntau dua. Yog hais tias tus txheej txheem tswj tsis raug, lub zos overheating yuav tshwm sim
- Hlau Specification:Txoj kab uas hla ntawm txoj kab sib txawv thiab qhov yuam kev roundness ntawm cov xaim ncaj qha cuam tshuam qhov nruj ntawm lub winding tom qab winding. Piv txwv li, thaum txoj kab uas hla ntawm txoj kab sib txawv tshaj 0.05mm, cov hlau yog qhov "qhov siab sib txawv" thaum lub sij hawm winding txheej txheem, uas ua rau ib tug tsis sib xws winding nto. Qhov no ua rau cov hluav taws xob tsis sib xws thaum lub sijhawm ua haujlwm thiab ua rau muaj kev pheej hmoo ntawm kev tso tawm ib nrab. Yog hais tias lub roundness tsis yog raws li tus qauv, nws yuav ua rau inconsistent xaim kev sib cuag cheeb tsam, ua rau unbalanced tam sim no faib thiab aggravating lub zos tshav kub tsim.
- Kev kho deg:Lub thickness thiab adhesion ntawm insulating xim zaj duab xis ntawm cov hlau nto yog qhov tseem ceeb heev. Lub siab - cov xim zoo nkauj yuav tsum muaj cov tuab tuab (nrog qhov ua yuam kev tsawg dua lossis sib npaug li 5%) thiab muaj zog adhesion. Yog hais tias cov xim zaj duab xis muaj pinholes, khawb, los yog tev, nws yuav txo tau qhov tig - mus rau -tig rwb thaiv tsev tsis kam, thiab tig - mus rau - tig tawg yuav tshwm sim thaum lub sij hawm ua hauj lwm, ncaj qha ua rau winding tsis ua hauj lwm.
2. Txoj kev Winding: Precision txiav "Stress Resistance".
Txoj kev winding yog qhov txuas tseem ceeb ntawm cov txheej txheem winding, thiab nws cov precision ncaj qha cuam tshuam rau lub zog ntawm lub zog thiab hluav taws xob qhov sib xws ntawm winding. Cov txheej txheem winding feem ntau suav nrog "ntau- txheej txheej cylindrical", "nruam hom", thiab qhov cuam tshuam ntawm ntau txoj hauv kev ntawm kev ruaj ntseg sib txawv:
- Winding Tension Control:Tsis sib xws thaum lub sij hawm winding txheej txheem yog lub ntsiab ua rau xoob windings. Yog tias qhov nro qis dhau lawm, yuav muaj qhov sib txawv ntawm cov xov hlau winding. Thaum lub sijhawm ua haujlwm, cov xaim xaim tuaj yeem hloov pauv raws li qhov kev txiav txim ntawm electromagnetic quab yuam, ua rau hnav ntawm txheej rwb thaiv tsev. Yog tias qhov nro siab dhau lawm, cov hlau tau yooj yim ncab thiab deformed, uas cuam tshuam rau tus ntoo khaub lig conductive -section thiab yuav ua rau cov xim insulating zaj duab xis puas. Kev ua haujlwm siab - cov txheej txheem zoo yuav tsum muaj qhov tsis siv neeg nruj tswj kev tswj xyuas qhov kev sib hloov ntawm qhov nro nyob rau hauv ± 5%, kom ntseeg tau tias lub winding yog nruj thiab tsis muaj kev puas tsuaj.
- Winding Precision:Qhov "tsis tu ncua" thiab "tightness" ntawm kev xaim xaim ncaj qha cuam tshuam rau kev faib hluav taws xob. Piv txwv li, yog tias "hloov tsis raug" lossis "overlapped lem" tshwm sim nyob rau hauv qhov nruam winding, lub zog hluav taws xob hauv cheeb tsam yuav nce siab (txog li 3 npaug ntawm thaj chaw ib txwm muaj), ua rau muaj qhov paug tawm. Yog tias qhov sib txawv ntawm - txheej sib txawv ntawm ntau - txheej cylindrical winding tshaj 0.1 hli, "air gap" yuav tsim. Txij li thaum lub zog tawg ntawm huab cua qis dua li ntawm cov ntawv insulating, inter-txheej txheej tawg tsis ua haujlwm yuav tshwm sim.
- Kev Kho Mob Kawg:Lub winding kawg yog lub concentrated cheeb tsam ntawm mechanical stress. Thaum lub sij hawm luv luv, lub zog hluav taws xob ntawm qhov kawg tuaj yeem ncav cuag ntau lub sijhawm uas nyob rau hauv ib txwm ua haujlwm. Yog tias qhov kawg khi tsis ruaj khov (piv txwv li, qhov sib nrug ntawm daim kab xev khi loj dhau, lossis cov pob qij txha tsis nruj), qhov kawg yog qhov yooj yim rau deformation thiab hloov chaw thaum lub sij hawm luv luv, uas ntxiv kua muag lub rwb thaiv tsev txheej. Kev ua haujlwm siab - cov txheej txheem zoo yuav tsum "ntau- txheej hla kev khi" thiab kev teeb tsa ntawm "pob rings" ntawm qhov kawg txhawm rau txhim kho cov neeg kho tshuab lub zog thiab ua kom cov duab ruaj khov ntawm winding thaum lub caij luv luv.
3. Kev kho rwb thaiv tsev: thaiv qhov "Fault Transmission Path".
Cov txheej txheem rwb thaiv tsev ntawm winding yog tus yuam sij rau kev tiv thaiv hluav taws xob thiab thermal stress. Qhov zoo ntawm cov txheej txheem rwb thaiv tsev kho mob ncaj qha txiav txim siab txog kev pab cuam lub neej thiab kev ntseeg siab ntawm cov txheej txheem rwb thaiv tsev:
- Kev xaiv cov khoom siv rwb thaiv tsev:Cov ntaub ntawv rwb thaiv tsev feem ntau suav nrog cov ntawv insulating, insulating xim, thiab spacers. Piv txwv li, qhov ntev -lub sij hawm ntsuas kub tsis kam ntawm Class A insulating ntawv yog 105 degree, thaum cov ntaub ntawv H insulating tuaj yeem ncav cuag 180 degree. Nyob rau hauv qhov chaw siab - qhov kub thiab txias (xws li cov chaw tsim hluav taws xob tshiab thiab cov chaw ua haujlwm metallurgical), xaiv Class H insulating ntawv tuaj yeem txuas lub neej kev pab cuam ntawm rwb thaiv tsev los ntawm 3-5 zaug. Yog tias cov khoom siv rwb thaiv tsev raug xaiv tsis raug, nws yog qhov ua rau kev laus thiab embrittlement ntawm qhov kub thiab txias, ua rau txo qis hauv rwb thaiv tsev.
- Impregnation thiab ziab txheej txheem:Lub hom phiaj ntawm kev kho impregnation yog tso cai rau cov xim insulating kom nkag mus rau hauv qhov khoob ntawm qhov winding, tsim ib qho "ib txheej rwb thaiv tsev". Yog hais tias lub impregnation tsis txaus (xws li, cov xim viscosity siab dhau lawm, los yog lub sij hawm impregnation tsis txaus), huab cua npuas yuav nyob twj ywm rau hauv lub winding. Lub zog tawg ntawm huab cua npuas yog tsawg, uas yooj yim ua rau ib nrab paug. Yog tias cov txheej txheem ziab tsis raug tswj kom zoo (piv txwv li, qhov kub thiab txias nce nrawm, lossis cov av noo tsis ua raws li tus qauv), nws yuav ua rau cov xim tsis sib xws ntawm cov xim insulating, ua rau tawg thiab tev, thiab poob cov nyhuv rwb thaiv tsev.
- Rwb thaiv tsev Thickness Control:Lub rwb thaiv tsev txheej thickness yuav tsum raug tsim raws li qhov ntsuas voltage ntawm lub transformer. Piv txwv li, tig - mus rau - tig rwb thaiv tsev thickness ntawm 10kV transformer yuav tsum siab tshaj los yog sib npaug rau 0.3mm. Yog hais tias lub thickness tsis txaus, nws yog yooj yim tawg los ntawm high voltage. Yog hais tias lub thickness yog tuab heev, nws yuav ua rau kom lub winding ntim, cuam tshuam rau tshav kub dissipation efficiency, thiab ua rau cov ntaub ntawv pov tseg. Lub siab - txheej txheem zoo yuav tsum tau "online thickness xyuas" kom ntseeg tau tias cov rwb thaiv tsev txheej thickness sib txawv tsawg dua los yog sib npaug rau 0.02mm.
4. Drying & Curing: Xauv hauv "Txheej Txheem Txheej Txheem".
Kev ziab thiab kho yog qhov kawg txuas ntawm cov txheej txheem winding. Nws lub hom phiaj yog kom tshem tawm cov dej noo los ntawm winding thiab xyuas kom meej tias cov xim insulating tau kho tag nrho. Yog tias tsis kho kom raug, qhov cuam tshuam ntawm cov txheej txheem dhau los yuav raug pov tseg:
- Moisture Control:Moisture nyob rau hauv winding yuav txo cov rwb thaiv tsev tiv thaiv thiab ua kom lub rwb thaiv tsev laus. Piv txwv li, thaum cov dej noo nyob rau hauv daim ntawv insulating siab tshaj 0.5%, nws lub zog tawg yuav txo qis dua 40%. Lub siab- txheej txheem ziab kom zoo yuav tsum "nqus kom qhuav" los tswj cov dej noo ntawm cov cua hauv qab 0.1%, thaum tsis txhob xaim oxidation vim qhov kub thiab txias heev.
- Curing Temperature thiab Sijhawm:Kev kho cov xim insulating yuav tsum ua raws li "stepwise kub nce" hauv paus ntsiab lus. Yog hais tias qhov kub thiab txias nce ceev heev, cov xim yuav ua rau "surface curing while internal uncuring", uas ua rau lub zog tsis txaus ntawm txheej rwb thaiv tsev. Yog tias lub sijhawm kho tsis txaus, cov xim insulating yuav tsis hla tag nrho - txuas, thiab nws yooj yim rau softening thiab ntws thaum lub sijhawm ua haujlwm ntev -. Piv txwv li, epoxy-raws li cov xim insulating yuav tsum tau khaws cia ntawm 120℃rau ntau tshaj 6 teev los xyuas kom meej qhov curing℃ntawm ntau dua los yog sib npaug li 95% thiab lav qhov kev ua haujlwm ruaj khov.
III. Optimization Directions of Winding Process: Los ntawm "Ua raws" mus rau "Excellence".
Rau cov tuam txhab tsim hluav taws xob, kev txhim kho kev ruaj ntseg ntawm cov txheej txheem winding yuav tsum muaj kev siv zog hauv peb yam: "khoom siv kho dua tshiab", "txheej txheem txheej txheem", thiab "kev sim txhim kho":
Automated Equipment Upgrading: Qhia tag nrho cov tshuab winding tsis siv neeg (nrog rau qhov nro kaw- lub voj voog tswj), kev ntsuas hluav taws xob hauv online, lub tshuab nqus tsev kom qhuav, thiab lwm yam khoom siv los txo cov kev ua haujlwm yuam kev thiab xyuas kom meej tswj cov txheej txheem tsis raug.
Tag Nrho-Txoj Kev Tswjhwm Zoo: Tsim kom muaj tag nrho- txheej txheem tswj kev npog "xaim nkag mus kuaj - winding txheej txheem tshuaj xyuas - rwb thaiv tsev kho cov qauv tshuaj xyuas - cov khoom tiav nrog qhov ntsuas hluav taws xob". Piv txwv li, cov xaim xaim xaim yuav tsum tau kuaj xyuas cov kab kab uas hla thiab xim zaj duab xis adhesion, thiab cov txheej txheem winding precision yuav tsum tau tshuaj xyuas txhua 100 lem thaum lub sij hawm winding txheej txheem.
Txhim khu kev ntseeg tau zoo: Kev ua tiav winding yuav tsum dhau peb qhov kev ntsuam xyuas tseem ceeb: "tig-to-tig tiv thaiv qhov ntsuas hluav taws xob", "kev ntsuas ib nrab", thiab "luv-circuit withstand test". Ntawm lawv, ib feem ntawm qhov tso tawm yuav tsum tau tswj qis dua 5pC (rau qib 10kV), thiab luv luv -circuit withstand test yuav tsum tiv taus qhov ntsuas luv luv -circuit tam sim no cuam tshuam rau 2 vib nas this kom ntseeg tau tias lub winding tseem ruaj khov txawm tias nyob rau hauv kev ua haujlwm hnyav.
IV. Xaus
Raws li "core technical barrier" nyob rau hauv transformer manufacturing, txhua yam ntawm cov txheej txheem winding yog ze ze rau cov khoom stability. Rau cov neeg siv, thaum xaiv lub transformer, lawv yuav tsum xyuam xim rau lub chaw tsim tshuaj paus lub winding txheej txheem muaj peev xwm (xws li seb nws muaj tsis siv neeg winding khoom thiab seb nws puas tau dhau lub International Electrotechnical Commission (IEC) daim ntawv pov thawj). Rau cov neeg tsim khoom, lawv yuav tsum tau hloov kho cov txheej txheem winding los ntawm "kev ua raws li qhov yuav tsum tau ua" mus rau "kev sib tw kom zoo dua" los ntawm cov txheej txheem optimization thiab kev kho dua tshiab, tso lub hauv paus ruaj khov rau lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm transformers.
