Nrog rau kev siv dav dav ntawm cov tsav tsheb sib txawv, servo, ups thiab lwm yam khoom, ntau qhov kev sib haum xeeb tau tshwm sim hauv daim phiaj hluav taws xob, thiab kev sib haum xeeb tau ua rau muaj teeb meem loj heev.Yuav kom daws tau qhov teeb meem sib haum xeeb hauv daim phiaj hluav taws xob, peb lub tuam txhab tau tsim peb theemnquag limraws li ob-theem active lim.
Active harmonic limtuaj yeem siv dav hauv kev lag luam, kev lag luam thiab chaw faib khoom, xws li: hluav taws xob tshuab, electrolytic plating tuam txhab, khoom siv kho dej, petrochemical tuam txhab, khw loj loj thiab chaw ua hauj lwm cov tsev, precision electronics qhauj, tshav dav hlau / chaw nres nkoj fais fab mov systems, kho mob cov tsev kho mob. , etc. Raws li cov khoom siv sib txawv, daim ntawv thov ntawmactive zog limyuav ua lub luag haujlwm hauv kev ua kom muaj kev ntseeg siab ntawm cov khoom siv hluav taws xob, txo cov kev cuam tshuam, txhim kho cov khoom zoo, ua kom cov khoom siv lub neej thiab txo cov khoom puas.
Qhov thib 3 harmonic nyob rau hauv feem ntau semiconductor industries yog heev loj, feem ntau yog vim muaj coob tus ib-theem rectification khoom siv nyob rau hauv cov lag luam.Qhov thib peb harmonic belongs rau xoom sequence harmonics, uas muaj cov yam ntxwv ntawm kev sib sau ua ke nyob rau hauv lub nruab nrab kab, uas ua rau lub siab tshaj plaws nyob rau hauv lub nruab nrab kab, thiab txawm ignition phenomenon, uas muaj ib tug zoo zais kev nyab xeeb nyob rau hauv ntau lawm kev ruaj ntseg.Harmonics tseem tuaj yeem ua rau cov hluav taws xob tawg mus rau qhov chaw, ncua sij hawm ntau lawm.Qhov thib peb harmonic daim ntawv ib ncig nyob rau hauv lub transformer thiab accelerates lub aging ntawm lub transformer.Cov pa phem hnyav hnyav yuav ua rau muaj kev cuam tshuam rau kev pabcuam kev ua haujlwm thiab lub neej ntawm cov khoom siv hauv cov khoom siv hluav taws xob.
Feem ntau ntawm cov inverter rectification txuas yog daim ntawv thov ntawm 6 pulses los hloov AC rau DC, yog li cov harmonics generated mas yog 5, 7, 11 zaug.Nws qhov kev phom sij tseem ceeb yog kev phom sij rau cov khoom siv hluav taws xob thiab kev sib txawv hauv kev ntsuas.Kev siv ntawmnquag limtuaj yeem yog qhov kev daws teeb meem zoo rau qhov teeb meem no.
Kev siv ntawmactive harmoniclim:
1. Lim tawm cov kev sib haum xeeb tam sim no, uas tuaj yeem lim tawm cov kev sib haum xeeb ntawm 2-25 zaug hauv kev thauj khoom tam sim no, txhawm rau ua kom cov khoom xa tawm kom huv thiab ua tau zoo, thiab ua tau raws li cov kev cai ntawm lub teb chaws tus qauv rau kev faib network clipping.Cov lim dej ua kom tau txais txiaj ntsig zoo tshaj plaws, tuaj yeem txheeb xyuas qhov kev hloov pauv tag nrho thiab thauj cov ntsiab lus sib haum xeeb thiab taug qab cov nyiaj them sai sai, 80us teb rau kev hloov pauv, 20ms kom ua tiav cov nyiaj them tag nrho.
2. Txhim kho qhov system tsis sib xws, tuaj yeem tshem tawm tag nrho cov kev tsis sib haum xeeb los ntawm kev sib haum xeeb, nyob rau hauv cov ntaub ntawv ntawm cov cuab yeej muaj peev xwm tso cai, tuaj yeem teem caij raws li tus neeg siv los them nyiaj rau qhov system tsis zoo ib ntus thiab xoom sequence imbalance Cheebtsam thiab nruab nrab them nyiaj reactive zog.
3. Inhibit lub resonance ntawm daim phiaj fais fab, uas yuav tsis resonate nrog daim phiaj fais fab, thiab muaj peev xwm simulate resonance ntawm daim phiaj fais fab nws tus kheej nyob rau hauv lub peev xwm ntawm nws lub peev xwm.
4. Ntau yam kev tiv thaiv kev ua haujlwm, nrog rau tam sim no, dhau voltage, nyob rau hauv voltage, siab kub, ntsuas Circuit Court txhaum, xob laim tawm tsam thiab lwm yam kev tiv thaiv kev ua haujlwm.
5. Kev ua haujlwm digital tag nrho, nrog tus phooj ywg txiv neej-tshuab interface, ua haujlwm yooj yim, siv tau yooj yim thiab tswj.
