Kev sib haum xeeb hauv qab yog ib qho tshwj xeeb scalar kom muaj nuj nqis, uas feem ntau tsis quav ntsej los ntawm cov tuam txhab tsim khoom feem ntau, txawm tias tom qab kev cuam tshuam ntawm cov tshuab thiab khoom siv, nws tsis tuaj yeem txiav txim siab cuam tshuam cov teeb liab.Tam sim no lub hwj huam mov system chav tsev muaj cov kev cai meej ntawm kev ntsuam xyuas ntawm cov tuam txhab siv hluav taws xob.Raws li lub teb chaws tus qauv: GB / T12326-2008 (lub hwj chim zoo voltage fluctuation thiab flicker), lub hwj chim mov chaw ua hauj lwm teev hais tias qhov voltage fluctuations generated los ntawm lub hwj chim noj tuam txhab uas muag yuav tsum tsawg tshaj li THDU (harmonic voltage fluctuation) txwv tus nqi, tab sis tus qauv no tsis tuaj yeem lav rau ntau lub tuam txhab uas siv cov khoom sib txawv ntawm qhov sib txawv, tshwj xeeb tshaj yog cov kev sib haum xeeb ntawm qhov hluav taws xob los ntawm kev thauj khoom xws li nruab nrab zaus induction furnaces thiab qhov sib txawv zaus ceev regulators.Nws yog qhov yooj yim heev kom dhau tus qauv nrog cov ruggedness!
Harmonic voltage yog "kis" los ntawm daim phiaj hluav taws xob rau kev tshaj tawm, thiab lub hauv paus ntawm harmonic voltage feem ntau muab faib ua peb pawg:
① Kev thauj mus los ntawm cov haujlwm tsis tsim nyog ntawm lub zog hluav taws xob kawg;
② Lub harmonic voltage hloov pauv los ntawm nws tus kheej cov cuab yeej tshaj tus qauv;
③Siv transformers nrog lwm lub tuam txhab, thiab cov khoom siv sib haum xeeb ntawm lwm lub tuam txhab yuav raug cuam tshuam;
Cov teeb meem tseem ceeb ntawm keeb kwm kev sib haum xeeb hauv kab hluav taws xob feem ntau suav nrog:
1. Lub tshuab tswj tsis siv neeg (frequency conversion ceev maub los code, PLC) ua haujlwm tsis raug thiab tsis tsim nyog;
2. Kev ua haujlwm ntawm cov tshuab ua haujlwm siab thiab cov khoom siv thiab cov cuab yeej tiv thaiv yog chaotic;
3. Cov khoom tiv thaiv relay ua tsis tiav;
4. Lub inverter ntaus ntawv tsis tuaj yeem ua haujlwm;
5. Lub luv luv-circuit txhaum ntawm peb-theem transformer ntsia hauv kev hloov pauv ntawm cov tsis muaj zog tam sim no, thiab lwm yam.
Qhov kev phom sij zoo li no yuav ua rau lub tuam txhab tsis ua haujlwm ntawm cov tshuab thiab cov khoom siv thiab kev sib tsoo ntawm cov kab ntau lawm, ua rau muaj kev puas tsuaj tag nrho thiab ua rau muaj kev puas tsuaj loj rau kev ruaj ntseg ntawm cov tshuab thiab khoom siv;
Nyob rau hauv niaj hnub kev lag luam ntau lawm, precision tshuab cuab yeej, tsis siv neeg ntau lawm kab, automation khoom, thiab hluav taws xob ntaus ntawv metrology thiab cov ntaub ntawv pov thawj yog dav siv.Lub tshuab tswj tsis siv neeg ua lub luag haujlwm ntawm tib neeg lub hlwb hauv txhua yam khoom siv, siv rau kev tso saib, kev ntsuas kev ntsuas siab, cov txheej txheem sib koom ua ke, thiab cov Stepper lub cev muaj zog, kev hloov pauv ceev thiab lwm yam tsis siv neeg siab, ua tiav kev tsim khoom sai.Txawm li cas los xij, qee lub tuam txhab feem ntau muaj qhov ua tsis tau zoo xws li ablation ntawm lub zog hluav taws xob sab hauv ntawm lub tshuab tswj tsis siv neeg, tsis siv neeg dhia ntawm cov lej, thiab PLC cov lus txib tsis raug, uas cuam tshuam rau kev tsim khoom thiab kev tsim khoom, ua rau lub tuam txhab nres kev tsim khoom thiab txo cov txiaj ntsig kev lag luam. .Tus neeg ua txhaum tom qab qhov xwm txheej no yog, muaj ntau qhov kev sib raug zoo tom qab ntawm daim phiaj fais fab!Ntau lub tuam txhab feem ntau muaj kev txhawj xeeb txog kev puas tsuaj los ntawm kev sib haum xeeb ib puag ncig ntawm lawv cov tshuab thiab khoom siv.Vim hais tias cov kev sib haum xeeb tam sim no tshaj tus qauv, lub reactive fais fab nyiaj them lub txee tsis tuaj yeem hloov tau, ua rau lub zog qis thiab raug rau txim los ntawm lub tuam tsev.Tam sim no nws yuav tsum tau hais meej tias keeb kwm kev sib haum xeeb yuav tsum tau saib xyuas thiab.Ntau lub tuam txhab tau tso tseg kev siv tshuab thiab khoom siv thiab cov txheej txheem ntau lawm vim muaj kev puas tsuaj ntawm keeb kwm yav dhau los, uas tau ua rau kev lag luam loj loj poob rau lub tuam txhab!
Muaj qhov sib txawv ntawm keeb kwm kev sib haum xeeb thiab cov neeg ua haujlwm sib haum xeeb ib puag ncig muaj kuab paug.Cov khoom siv tswj kev sib haum xeeb los ntawm lub tuam txhab nws tus kheej yog lub lim dej uas txhua tus paub txog.Nws yeej yog nyob ntawm kev them nyiaj rau qhov hloov pauv ntawm cov kev sib haum xeeb tam sim no thiab tiv thaiv cov kev sib haum xeeb los ntawm kev cuam tshuam lossis txawm tias puas tsuaj rau lub tuam txhab cov khoom siv., kom txo tau ib puag ncig muaj kuab paug rau hauv daim phiaj fais fab;Txawm li cas los xij, qee lub tuam txhab cov tshuab thiab cov cuab yeej tsis ua kom muaj kev sib haum xeeb lossis ua rau muaj kev sib haum xeeb tsawg, thiab qee lub tuam txhab tau tsim muaj cov khoom siv lim dej, tab sis cov tshuab thiab cov tshuab tswj tsis siv neeg tseem feem ntau cuam tshuam los ntawm kev sib haum xeeb, ua rau tsis meej pem hauv kev tswj tsis siv neeg, ablation. ntawm me me transformers, tsis ua hauj lwm ntawm precision tshuab cuab yeej thiab lwm yam faults!Cov xwm txheej zoo li no yuav tshwm sim los ntawm keeb kwm kev sib raug zoo.Txawm hais tias lub lim dej ua haujlwm raug teeb tsa, yuav tsis muaj kev vam meej.Lub sijhawm no, peb yuav tsum xaiv cov khoom siv lim dej kom ua tau zoo nrog cov kev cuam tshuam los ntawm qhov sib txawv ntawm qhov hluav taws xob!
Cov khoom siv lim dej siv cov khoom siv hluav taws xob hloov pauv raws li lub hom phiaj tswj, thiab nws tuaj yeem paub zoo txog kev zom zaub mov, nqus, txo qis thiab kev tiv thaiv kev sib cais ntawm sab nraud tom qab kev sib haum xeeb.Purification khoom kho mob.Nws tuaj yeem kho ntau yam kev hloov pauv ntawm qhov hluav taws xob thiab muab kev ruaj khov hloov hluav taws xob rau cov khoom siv hluav taws xob siab.Nws yog raws li cov hauv paus ntsiab lus ntawm cov hlau nplaum series resonance thiab microwave sensor filtering.Nws muaj kev ruaj ntseg siab heev thiab tuaj yeem suav tau tias yog lub zog hloov hluav taws xob ib nrab.Nws yog tshwj xeeb tshaj yog haum rau daim ntaub ntawv nyob rau hauv huab tej yam ntuj tso ib puag ncig xws li industrial ntau lawm.Lub lim yog txawv los ntawm kev tswj hwm lub hwj chim.Nws tuaj yeem tsis tsuas yog tso tawm qhov ruaj khov AC voltage, tab sis kuj tshem tawm cov kev sib haum xeeb, kev tiv thaiv hluav taws xob, thiab RF cuam tshuam qhov hluav taws xob hauv qhov hluav taws xob input.
