Yuav Ua Li Cas Xaiv Ib Lub Zog Siv Hluav Taws Xob (APF)
Dec 05, 2025| I. Dab tsi yog qhov Active Power Filter (APF)?
Ib qho Active Power Filter (APF) yog cov khoom siv sib haum xeeb raws li kev siv hluav taws xob hluav taws xob. Nws ua haujlwm los ntawm kev txheeb xyuas qhov sib haum xeeb hauv lub zog hluav taws xob hauv lub sijhawm tiag tiag- thiab tsim cov nyiaj them rov qab rau cov kev sib raug zoo los ntawm lub inverter kom tshem tawm lawv.
II. Kev sib raug zoo ntawm Harmonic yam ntxwv thiab kev xaiv APF
1. Hom Harmonics
Kev xaiv ntawm Active Power Filter nyob ntawm seb hom kev sib haum xeeb los txiav txim siab nws cov nyiaj them ntau npaum li cas. Feem ntau, APFs tuaj yeem teeb tsa los lim cov zaus tshwj xeeb, tiv thaiv qee yam kev sib haum xeeb.
2. Qhov loj ntawm Harmonics
Qhov loj ntawm harmonics sawv cev rau theem ntawm kev sib kis uas lawv qhia rau lub zog hluav taws xob. Kev sib haum xeeb siab dua tuaj yeem ua rau muaj teeb meem xws li qhov cuam tshuam ntawm qhov hluav taws xob thiab cov khoom siv overheating. Yog li, APF cov cuab yeej yuav tsum muaj peev xwm tuav cov kev sib haum xeeb ntawm qhov sib txawv. Thaum xaiv, nws yog ib qho tseem ceeb uas yuav tau xaiv APF uas muaj peev xwm them nyiaj txaus raws li qhov sib haum xeeb muaj nyob hauv lub zog hluav taws xob.
3. Zaus ntawm Harmonics
Cov yam ntxwv ntawm cov lus teb zaus ntawm Active Fais Fab Lim yuav tsum npog qhov ntau ntawm cov zaus sib haum xeeb tam sim no hauv lub zog hluav taws xob. Feem ntau, siab -kev ua tau zoo APF cov cuab yeej tuaj yeem kho qhov sib haum xeeb ntawm cov zaus sib txawv, ua kom muaj kev sib haum xeeb thiab muaj txiaj ntsig zoo.
III. Xaiv APF Cov Khoom Siv raws li cov yam ntxwv Load
1. Variable Frequency Drive (VFD) Loads
Variable Frequency Drives (VFDs) yog ib qho chaw ntawm kev sib haum xeeb, nrog rau qhov thib peb thiab thib tsib harmonics yog qhov tseem ceeb. Rau VFD- tsav tsheb thauj khoom, kev xaiv APF yuav tsum ua qhov tseem ceeb ntawm lub peev xwm los txo qis - zaus harmonics, xws li qhov thib peb harmonics. Ib qho khoom siv APF zoo tshaj plaws yuav tsum teb sai sai thiab tshem tawm cov kev sib haum xeeb hauv lub sijhawm luv luv kom ntseeg tau tias kev ua haujlwm zoo ntawm VFD.
2. Highly Nonlinear Loads xws li hluav taws xob Arc rauv
Highly nonlinear loads xws li hluav taws xob arc furnaces tsim cov ntsiab lus tseem ceeb nrog kev hloov pauv loj. Nyob rau hauv ib puag ncig zoo li no, APF xaiv yuav tsum muaj lub peev xwm teb tau zoo los kuaj xyuas thiab them nyiaj rau kev hloov pauv sai sai hauv lub sijhawm tiag tiag -.
Thaum xaiv ib qho khoom siv APF uas tsim nyog, ntxiv rau kev txiav txim siab txog hom, qhov loj me, thiab zaus ntawm kev sib haum xeeb, nws tseem yog qhov tseem ceeb rau kev ntsuas cov yam ntxwv xws li cov yam ntxwv ntawm kev thauj khoom, kev ruaj ntseg, thiab cov lus teb muaj peev xwm ntawm cov khoom siv.
