Harmonics cuam tshuam rau IT, kev sib txuas lus / tuam txhab nyiaj hauv ob txoj hauv kev: kev coj ua thiab hluav taws xob.Cov xwm txheej kis tau yog hais txog qhov sib haum xeeb tam sim no nkag mus rau hauv lub zog hluav taws xob network los ntawm cov khoom siv hluav taws xob tam sim no xws li cov hloov pauv.Qhov teeb meem ntawm hluav taws xob yog tias cov hluav taws xob sib haum xeeb tau nkag mus rau hauv kev sib txuas lus.Raws li tau hais los saum toj no hauv qhov kev qhia tshwj xeeb, "Lub hom phiaj ntawm qhov kev qhia tshwj xeeb yog txhawm rau txo qhov kev sib haum xeeb tiag tiag hauv cov khoom siv hluav taws xob mus rau qib (adaptive level) uas yuav tsis ua rau muaj kev phom sij rau cov khoom siv rhiab heev.Tib neeg cov teebmeem kev sib haum xeeb feem ntau yog rau kev sib haum xeeb Cov kev cuam tshuam ntawm nthwv dej tam sim no thiab cov yam ntxwv impedance ntawm kev sib haum xeeb ua haujlwm voltage tshwm sim los ntawm kev sib kis software.
Kev puas tsuaj ntawm hluav taws xob engineering harmonics rau daim phiaj hluav taws xob yog nyob ntawm qhov kev puas tsuaj ntawm kev sib haum xeeb ua haujlwm voltage rau cov tshuab thiab cov khoom siv hauv daim phiaj hluav taws xob, uas yog, qhov kev sib haum xeeb ua haujlwm voltage tshaj li cov tshuab thiab cov cuab yeej siv tau.Lub hwj chim mov tog yog lub luag hauj lwm rau lub pulse tam sim no ua hauj lwm voltage ntawm lub hwj chim mov network, thiab cov neeg siv hluav taws xob yog lub luag hauj lwm los qhia cov harmonic tam sim no ntawm lub system software.
Txhawm rau txo qhov kev puas tsuaj ntawm kev sib haum xeeb rau lub zog hluav taws xob thiab kev faib tawm, lub tswv yim tseem ceeb yog pib nrog qhov sib haum xeeb, sim zam qhov kev sib haum xeeb tam sim no nyob ib puag ncig ntawm qhov sib haum xeeb, thiab tom qab ntawd txo qhov kev sib haum xeeb.Txoj hauv kev kom tsis txhob muaj kev puas tsuaj tam sim no yog txhawm rau txhim kho AC lim, uas tuaj yeem tsim kom muaj kev sib haum xeeb tam sim no, txo qhov kev hloov pauv hauv kev khiav hauj lwm voltage ntawm daim phiaj hluav taws xob, thiab txhim kho qhov zoo ntawm cov hluav taws xob xa hluav taws xob thiab kev faib tawm.Tsis tas li ntawd, nws tuaj yeem hloov kho siv qhov ua haujlwm siab ntawm lub zog thauj khoom, thiab kev pabcuam lub neej yog qhov ntev.Ntxiv, lub lim muab lub capacitive reactive load, uas muaj ib tug tej yam reactive hwj chim them nyiaj, yog li txhim kho lub hwj chim ntawm lub system.Raws li seb lub voj tseem ceeb suav nrog cov khoom siv, cov ntxaij lim dej tuaj yeem muab faib ua cov lim dej ua haujlwm thiab cov lim dej tsis zoo.
Nrog rau txoj kev loj hlob ntawm cov ntaub ntawv thev naus laus zis, kev sib txuas lus / kev lag luam credit, txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm lub khoos phis tawj tseem ceeb ntawm cov chaw loj thiab nruab nrab cov ntaub ntawv, daim ntawv thov ntim ntawm cov khoom sib haum xeeb xws li ups fais fab mov hauv cov khoom siv hluav taws xob. system software ntawm cov ntaub ntawv thev naus laus zis, kev sib txuas lus / tuam txhab nyiaj txiag tau nce ntxiv.Lub ntsiab harmonic qhov chaw ntawm lub low-voltage fais fab tis system ntawm cov ntaub ntawv technology, kev sib txuas lus / nyiaj txiag cov koom haum muaj xws li UPS fais fab mov, fais fab transformer, zaus converter cua txias, thiab lwm yam. Lub harmonic tam sim no cov ntsiab lus generated los ntawm cov khoom ntawm ntau manufacturers txawv heev, tab sis nws yog feem ntau siab.Thaum tag nrho cov harmonic distortion tus nqi THDi ntawm qhov tam sim no tshaj 50% (feem ntau tshaj 30%), lub 5th, 7th, thiab 11th harmonics tam sim no hnyav heev, qee zaum muaj ntau tshaj 3 harmonics.
Tus neeg siv tus nqi ntawm Harmonic Kev Tswj Xyuas
Txhim kho kev ntseeg siab ntawm cov neeg siv khoom sib txuas lus thiab cov khoom siv hluav taws xob faib hluav taws xob software, ua kom lub neej kev pab cuam ntawm cov neeg siv khoom sib txuas lus thiab hluav taws xob engineering;txhim kho kev sib txuas lus zoo ntawm kev sib txuas lus cov ntaub ntawv teeb liab, xyuas kom txhua qhov kev sib txuas lus ntawm cov ntaub ntawv sib txuas lus thiab kev ua haujlwm ntawm cov khoom siv sib txuas lus;tshem tawm cov kev pheej hmoo ntawm kev nyab xeeb xws li overheating ntawm cov khoom siv hluav taws xob, overheating ntawm cov fais fab cables, txo qhov muaj peev xwm nqa tam sim no, thiab qhov hluav taws xob yoj thav duab poob los ntawm cov mem tes tam sim no ntawm cov khoom siv hluav taws xob xws li UPS cov khoom siv hluav taws xob;nce kev siv hluav taws xob ntawm nruab nrab cua txias thiab lwm yam khoom siv hauv tsev, thiab txhim kho lub zog Lub zog ntawm cov software ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab txo qis emission.
Tej zaum koj yuav ntsib teeb meem?
1. Cov cuab yeej siv hluav taws xob tam sim no tsis tuaj yeem ua haujlwm ib txwm lossis feem ntau hlawv;
2. Nyob rau hauv kev sib txuas lus systems, harmonics cuam tshuam nrog cov kev sib txuas lus nyob ib sab.Lub suab nrov tsawg, qhov kev sib txuas lus tsis zoo, lub computer yuav tsis ua haujlwm zoo, thiab qhov hnyav dua, cov ntaub ntawv yuav ploj, ua rau lub cev poob.
3. Kev tiv thaiv relay tsis ua haujlwm lossis ua haujlwm tsis zoo, qhov ntsuas hluav taws xob ntsuas tsis ntsuas qhov tseeb, thiab cov khoom siv hluav taws xob precision yuav raug cuam tshuam loj lossis puas.
Peb qhov kev daws teeb meem:
1. Siv Hongyan passive lim cov cuab yeej los muab ib qho qis impedance channel rau kev sib haum xeeb ntawm qee zaus, thiab tshem tawm cov kev sib haum xeeb kom ua tiav cov kev cuam tshuam ntawm kev sib haum xeeb tiv thaiv thiab kev siv hluav taws xob reactive.
2. Siv cov lim dej ua haujlwm Hongyan APF los tswj cov kev sib haum xeeb, thiab cov khoom siv kev nyab xeeb zoo li qub los them cov hluav taws xob reactive ntawm lub cev, kom cov ntsiab lus sib haum xeeb thiab lub zog ntawm lub cev tuaj yeem ua tau raws li peb lub tuam txhab cov qauv.
3. Cov lim dej ua haujlwm Hongyan APF tau txais yuav, feem ntau ntawm cov capacitors ntawm lub lim dej lim dej tshem tawm cov lim dej sib haum xeeb, thiab ib feem ntawm lub capacitor compensates lub reactive zog, txhim kho lub hwj chim, thiab zoo tswj cov harmonics thiab reactive zog ntawm lub system. .
