Hauv cov xwm txheej uas muaj kev cuam tshuam loj heev, yuav tsum siv APF lim lossis lwm yam khoom siv?
Nov 23, 2025| Hauv cov xwm txheej uas muaj kev cuam tshuam loj heev, cov kev daws teeb meem muaj xws li siv Active Power Filters (APF) thiab lwm yam khoom siv lim.
I. Ua rau thiab cuam tshuam ntawm Harmonic Distortion
Harmonic distortion feem ntau yog tshwm sim los ntawm tsis yog -linear loads nyob rau hauv lub hwj chim system. Cov kev sib haum xeeb no feem ntau yog qhov sib npaug ntawm qhov tseem ceeb zaus thiab tuaj yeem cuam tshuam nrog daim phiaj xwm txheej, ua rau cov teeb meem hauv qab no:
1. Kev puas tsuaj rau cov khoom siv hluav taws xob: Harmonics tuaj yeem ua rau muaj kev puas tsuaj ntxiv hauv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog ua rau kub dhau ntawm cov khoom siv xws li cov motors thiab transformers, uas yuav ua rau cov cuab yeej tsis ua hauj lwm thaum mob hnyav.
2. Kev poob qis hauv lub zog tsis zoo: Cov pa phem cuam tshuam rau qhov zoo ntawm kev xa hluav taws xob, ua rau muaj qhov tsis muaj zog, uas cuam tshuam rau kev tsim khoom thiab kev ua haujlwm ntawm cov khoom siv.
3. Kev siv hluav taws xob tsawg: Harmonics tuaj yeem txo lub zog ntawm lub zog hluav taws xob, ua kom lub cev poob qis, thiab txo qis zog tag nrho.
II. Qhov zoo ntawm APF Active Power Filters
APF Active Power Filters yog cov khoom siv feem ntau siv rau kev sib haum xeeb. Qhov zoo ntawm APF lim muaj xws li:
1. High-kev ua tau zoo harmonic tshem tawm muaj peev xwm: APF tuaj yeem tshem tawm ntau yam kev sib haum xeeb, nrog rau siab -kev txiav txim siab sib haum xeeb, thiab muaj kev cuam tshuam zoo rau kev sib haum xeeb hauv ntau qhov ntau zaus, ua rau nws tsim nyog rau cov xwm txheej uas muaj kev sib haum xeeb loj.
2. Ceev ceev dynamic teb ceev: APF tuaj yeem saib xyuas kev sib haum xeeb hauv lub zog ntawm lub sijhawm thiab kho cov tswv yim them nyiaj sai. Qhov no ua rau nws tshwj xeeb tshaj yog haum rau cov xwm txheej uas muaj qhov hloov pauv loj, xws li cov khoom siv tsav tsheb sib txawv lossis hluav taws xob arc rauv taws.
3. Muaj zog yoog raws: Tsis zoo li cov lim dej tsis zoo, APF tuaj yeem hloov kho nws cov peev txheej them nyiaj raws li kev hloov pauv hauv kev sib haum xeeb, hloov mus rau qhov chaw muaj zog.
