Hauv -} qhov tob tob ntawm lub harmonic lim lub peev xwm ntawm apf (nquag siv fais fab lim) khoom siv
Jul 28, 2025| Hauv kev tswj hwm niaj hnub kev tswj hwm, APF (nquag siv fais fab lim) tau dhau los ua cov cuab yeej tseem ceeb vim nws muaj peev xwm ua tau zoo tshaj plaws vim nws muaj peev xwm ua tau zoo tshaj plaws vim nws cov peev txheej harmpression ntxiv vim nws cov peev txheej harmression muaj peev xwm. Txawm li cas los xij, ntau tus neeg siv enterprise tsis paub meej txog qhov tseeb harmonic filting muaj peev xwm ntawm APF. Tom ntej no, peb yuav txheeb xyuas lub harmonic sppression thiab lim lub peev xwm ntawm APF!
Ⅰ. Yooj yim har harmonic lim lub peev xwm
1. Tus qauv APF (nquag lim dej) Ntaus inverter tuaj yeem siv cov nyhuv ntawm 2 mus rau qhov tsis muaj txiaj ntsig ntawm qhov tsis yog {{tus yam ntxwv zoo. Cov ntaub ntawv sim qhia tau hais tias rau qis - Kev txiav txim siab ua rau muaj kev phom sij xws li 5 thiab 7, cov lim lim ntawm cov lim apf nquag tuaj yeem ncav cuag 95%.
2. Rau siab - Kev txiav txim siab ua rau muaj kev phom sij nrog ntau dua 23 lub voj voog, nws tseem tuaj yeem tswj kev siv lim dej ntau tshaj 85%. Qhov no dav - Kev tswj hwm kev tswj hwm tau ua rau nws haum rau cov khoom siv harcon uas muaj cov hloov pauv ntau dua li cov hloov pauv thiab kho cov khoom.
Ii. Qhov cuam tshuam ntawm cov kev ntsuas ntawm cov nyhuv pom
1. Qhov tseeb harmonic filting muaj peev xwm ntawm APF (nquag ua kom pom cov tswj hwm ntawm kev sib raug zoo (10 kHz piv txwv txog kev muaj peev xwm txheeb xyuas 50 qhov kev sib raug zoo);
2. Tus hloov pauv zaus ntawm IGBT cuam tshuam rau kev them nyiaj ntau tshaj plaws uas tau them ntau tshaj plaws (feem ntau yog 1/10 ntawm kev hloov pauv zaus);
3. Lub kaw lus muaj peev xwm txiav txim tag nrho cov nyiaj ntawm kev ua kom zoo nkauj uas tuaj yeem them nyiaj. Kev kuaj pom tau pom tias thaum lub harmonic tam sim no ntau tshaj 120% ntawm lub peev txheej ntawm apf nquag lim, kev them nyiaj yuav yooj yim rau hauv qab 60%. Yog li ntawd, kev xaiv ntawm lub peev xwm tsim nyog yog ntawm qhov tseem ceeb tshaj plaws.
III. Tshwj Xeeb Harmonic tswj thev naus laus zis
1. To address the demand for the mitigation of ultra-high order harmonics (>50th, Lub Cim Tshiab ntawm Apf (nquag siv fais fab lim) tau saws cov qauv thev naus laus zis tau tsa cov sib npaug hloov mus rau saum 50 khz.
2. Cov txheej txheem lim cov algorithm tuaj yeem txheeb xyuas cov khoom sib haum xeeb hauv 150 mus.
3. Qhov kev hloov kho cov kev rov ua haujlwm thaum ub suppression ua si tuaj yeem tiv thaiv lub amplification ntawm high- zaus misconics. Hauv cov chaw sib txawv xws li cov ntaub ntawv cov ntaub ntawv, cov siab -}} Lub zog ua kom zoo rau cov khoom siv hluav taws xob ua kom zoo rau cov khoom siv ua kom zoo rau cov khoom siv ua ntej.
Lub harmonic lim lub peev xwm ntawm APF (nquag siv fais fab lim) tau nthuav dav los ntawm cov tsoos 50th Harmonics, ntsib qhov xav tau ntawm cov xwm txheej muaj kev lag luam. Thaum xaiv, nws yog ib qho tsim nyog kom muaj kev nkag siab tsis xws li Harmonic Spectrum, Kev Kho Mob kom tob, thiab teb ceev. Nws raug nquahu kom tau txais 20% muaj peev xwm npoo los daws tau kev thauj khoom.
