Lub zog fais fab DC siab yog ua los ntawm cov khoom siv zoo IGBTs uas xa tawm los ua lub zog tseem ceeb, thiab siv cov khoom siv ultra-microcrystalline (tseem hu ua nanocrystalline) mos mos magnetic alloy ua lub hauv paus tseem ceeb ntawm lub transformer. Lub kaw lus tswj hwm tseem ceeb siv cov thev naus laus zis tswj hwm ntau lub voj voog, thiab cov qauv yog cov ntsev-pov thawj, cov ntsuas acidification pos huab. Lub zog fais fab muaj cov qauv tsim nyog thiab muaj kev ntseeg siab. Hom fais fab no tau dhau los ua cov khoom hloov tshiab ntawm SCR fais fab vim nws qhov me me, lub teeb yuag, kev ua haujlwm siab thiab kev ntseeg siab siab.
Lawv siv dav hauv cov chaw tsim hluav taws xob loj, cov chaw tsim hluav taws xob hydropower, cov chaw hloov pauv hluav taws xob siab heev, cov chaw hloov pauv tsis muaj neeg saib xyuas ua kev tswj hwm, teeb liab, tiv thaiv, rov ua haujlwm tsis siv neeg, teeb pom kev thaum muaj xwm txheej ceev, DC twj tso kua roj, kev sim, oxidation, electrolysis, zinc plating, nickel plating, tin plating, chrome plating, photoelectric, smelting, kev hloov pauv tshuaj lom neeg, corrosion thiab lwm yam kev kho qhov chaw. Hauv anodizing, vacuum coating, electrolysis, electrophoresis, kev kho dej, kev laus khoom siv hluav taws xob, hluav taws xob cua sov, electrochemistry, thiab lwm yam, nws kuj tau txais kev nyiam los ntawm ntau thiab ntau tus neeg siv. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam electroplating thiab electrolysis, nws tau dhau los ua thawj qhov kev xaiv rau ntau tus neeg siv khoom.
Cov yam ntxwv tseem ceeb:
1. Me me thiab lub teeb yuag:
Qhov ntim thiab qhov hnyav yog 1/5-1/10 ntawm SCR lub zog muab hluav taws xob, uas yooj yim rau koj los npaj, nthuav dav, tsiv teb tsaws chaw, tswj thiab teeb tsa.
2. Cov qauv ntawm lub voj voog muaj ntau yam thiab yoog tau, thiab muaj peev xwm muab faib ua qhov dav-kho tau, zaus-modulated, ib-kawg thiab ob-kawg. Cov khoom siv fais fab DC zaus siab uas haum rau cov xwm txheej thov tuaj yeem tsim raws li qhov xwm txheej tiag tiag.
3. Kev txuag hluav taws xob zoo:
Lub zog hloov pauv siv lub tshuab hloov pauv zaus siab, qhov ua tau zoo ntawm kev hloov pauv tau zoo heev. Hauv qhov xwm txheej ib txwm muaj, qhov ua tau zoo dua li ntawm SCR cov khoom siv ntau dua 10%, thiab thaum tus nqi thauj khoom qis dua 70%, qhov ua tau zoo dua li ntawm SCR cov khoom siv ntau dua 30%.
4. Kev ruaj khov ntawm cov zis siab:
Vim yog qhov ceev teb ntawm lub kaw lus (qib microsecond), nws muaj kev hloov pauv zoo rau lub zog network thiab kev hloov pauv thauj khoom, thiab qhov tseeb ntawm cov zis tuaj yeem zoo dua 1%. Lub zog hloov pauv muaj kev ua haujlwm zoo, yog li qhov tseeb ntawm kev tswj hwm yog siab, uas yog qhov zoo rau kev txhim kho cov khoom zoo.
5. Daim ntawv nthwv dej tso zis yooj yim rau kev hloov kho:
Vim yog qhov ua haujlwm ntau zaus, tus nqi ua haujlwm sib piv ntawm kev hloov kho cov zis waveform yog qhov tsawg, thiab cov zis waveform tuaj yeem hloov pauv tau yooj yim dua raws li cov txheej txheem ntawm tus neeg siv. Qhov no muaj kev cuam tshuam loj heev rau kev txhim kho qhov chaw ua haujlwm zoo thiab txhim kho qhov zoo ntawm cov khoom tiav.
