Yuav ua li cas thiaj ua tau txoj haujlwm zoo hauv kev saib xyuas lub zog zaus converters
1. Raws li qhov tseeb ib puag ncig, txiav txim siab qhov ntev ntawm lub voj voog lub sijhawm rau kev tshuaj xyuas thiab kev saib xyuas ntawm lub tshuab hloov zaus. Yog tias tsim nyog, disassemble, tshuaj xyuas, ntsuas, tshem cov plua plav, thiab ua kom nruj lub rectifier module, inverter module, thiab Circuit Court board hauv lub txee tswj. Vim yog qhov tsis tshua muaj qhov thaiv ntawm cov cua nkag hauv qab thiab lub qhov hluav taws xob sab saud ntawm lub tshuab hluav taws xob zaus vim muaj plua plav los yog cov plua plav ntau dhau, lub peev xwm ntawm cov cua kub dissipation yog siab thiab qhov cua yuav tsum tau ua. Yog li ntawd, tom qab ua haujlwm rau qee lub sijhawm, muaj plua plav tsub zuj zuj ntawm lub rooj tsavxwm Circuit Court (vim hluav taws xob zoo li qub), uas yuav tsum tau ntxuav thiab tshuaj xyuas.
2. Tom qab kho lub rooj tsav xwm hauv Circuit Court, busbar, thiab lwm yam, yuav tsum tau ua raws li kev kho mob tiv thaiv corrosion, cov xim rwb thaiv tsev yuav tsum tau siv, thiab lub busbar uas tau dhau los ua ib feem ntawm qhov paug los yog arcing yuav tsum tau deburred thiab insulated. Rau cov kab hluav taws xob uas tau raug rwb thaiv tsev thiab tawg, carbonization yuav tsum tau muab tshem tawm lossis hloov.
3. Tshawb xyuas thiab ceev txhua qhov txuas txuas txuas kom tsis txhob muaj cua sov loj los ntawm kev xoob.
4. Ua ib qho kev tshuaj ntsuam xyuas thiab ntsuas qhov ntsuas ntawm cov tswv yim (nrog rau cov zis) terminals, rectifier modules, inverter modules, DC capacitors, thiab ceev melting li. Yog tias ib qho khoom siv tau pom tias raug hlawv lossis muaj qhov hloov pauv tseem ceeb, lawv yuav tsum tau hloov raws sijhawm.
5. Tsis tu ncua thiab ua tib zoo xyuas cov xwm txheej ntawm kev sib hloov ntawm lub kiv cua hauv lub tshuab hloov zaus. Tom qab lub hwj chim raug txiav tawm, tig lub kiv cua los ntawm txhais tes, saib seb cov bearings yog daig los yog tsis tig flexibly, thiab hloov lawv yog tias tsim nyog.
6. Ua tib zoo tshuaj xyuas cov khoom siv hluav taws xob ntawm lub rooj tsav xwm tswj xyuas, xyuas thiab tswj cov xwm txheej txawv txav xws li solder detachment, discoloration, bulging, cracking, thiab wire breakage (luam tawm Circuit Court). Yog tias tsim nyog, cov khoom uas muaj qhov txawv txav tuaj yeem raug ntsuas thiab hloov los ntawm lub rooj tsav xwm hauv Circuit Court.
Hauv kev xyaum, qhov txo qis hauv capacitor muaj peev xwm cuam tshuam ncaj qha rau qhov chaw ua haujlwm, qhov loj me, kev ua haujlwm, thiab lwm yam kev hloov pauv ntawm zaus. Ib puag ncig hnyav, kev thauj khoom loj, kev kaw ntau zaus, thiab lwm yam kev ua haujlwm tuaj yeem ua rau kev laus ntawm DC lub ntsiab capacitor. Tsis tas li ntawd, thaum lub sij hawm tu, nws yog ib qho tsim nyog yuav tsum ua tib zoo tshuaj xyuas lub ntsiab DC Circuit Court capacitor rau txhua qhov xau, nthuav dav, blistering lossis deformation ntawm lub plhaub, thiab seb qhov kev nyab xeeb valve qhib. Lub peev xwm capacitor, cov xau tam sim no (qhov hluav taws xob hluav taws xob siab tuaj yeem ua rau overheating ntawm lub capacitor, ua rau qhov kev nyab xeeb valve qhib, lossis txawm tias lub capacitor tawg), thiab qhov voltage kuj yuav tsum tau kuaj. Capacitors nrog lub peev xwm txo qis dua 30 feem pua, cov dej ntws tam sim no tshaj 70mA, thiab qhov hluav taws xob tsis zoo hauv qab 650V yuav tsum tau hloov raws sijhawm. Rau cov capacitors tshiab lossis capacitors uas tsis tau siv rau lub sijhawm ntev, kev ntsuas kev ua haujlwm yuav tsum tau ua kom tau raws li qhov yuav tsum tau siv ua ntej lawv tuaj yeem hloov pauv.
8. Rau cov khoom siv uas muaj peev xwm nqa tam sim no xws li rectifier blocks thiab inverter GTRs (lossis IGBTs), cov cuab yeej thiab cov cuab yeej xws li multimeter thiab choj yuav tsum tau siv rau kev ntsuas thiab qhov ntsuas qhov ntsuas. Qhov tseem ceeb rau pem hauv ntej thiab thim rov qab yuav tsum tau ntsuas thiab sau rau hauv ib lub rooj. Modules uas muaj qhov sib txawv tseem ceeb yuav tsum tau hloov.
9. Tshawb xyuas lub ntsiab contactor thiab lwm yam auxiliary relays, ua tib zoo saib seb cov dynamic thiab zoo li qub ntawm txhua tus contactor muaj arcing, burrs, los yog nto oxidation, unevenness, thiab lwm yam. Yog tias muaj teeb meem zoo li no, cov kev sib cuag dynamic thiab zoo li qub yuav tsum tau hloov. kom muaj kev nyab xeeb thiab txhim khu kev qha.
10. Tsis tu ncua xyuas qhov hloov pauv ntawm qhov hluav taws xob hloov hluav taws xob zaus. Peb yuav tsum tau txhim kho qhov tshwm sim ntawm zaus converters nyob rau hauv tshwj xeeb kev pab cuam ib puag ncig thiab loj load fluctuations kom tsis txhob muaj kev cuam tshuam ntawm high tam sim no ntawm lub zaus converter, uas tej zaum yuav cuam tshuam rau nws ib txwm ua hauj lwm.
Kev hloov pauv zaus tau siv dav hauv kev lag luam xws li metallurgy, petrochemical, lub zog, tshuab, thiab cov khoom siv hauv pej xeem vim lawv qhov dav dav, cov lus teb ceev ceev, kev ceev ceev cov neeg raug, ua tiav kev tiv thaiv, thiab kev ua haujlwm yooj yim. Feem ntau, tom qab siv lub zaus hloov pauv rau li 7 xyoo, nws yuav nkag mus rau lub sijhawm ua haujlwm tsis tu ncua, uas tuaj yeem ua rau cov khoom siv hluav taws xob tsis zoo, tsis ua haujlwm, nquag ua haujlwm ntawm kev tiv thaiv kev ua haujlwm, thiab lwm yam kev ua txhaum, cuam tshuam rau nws cov haujlwm ib txwm muaj.
