Tam sim no, lub peev xwm tswj kev sib haum xeeb zoo tshaj plaws hauv kev ua lag luam yog APF series qis-voltage nquag lim tsim thiab tsim los ntawm Hongyan Electric.Qhov no yog lub zog hluav taws xob tivthaiv raws li kev soj ntsuam tam sim no thiab kev siv thev naus laus zis tam sim no.Lub harmonic tam sim no tivthaiv yuav tsum tau compensated yog tau raws li kev soj ntsuam load tam sim no waveform.Los ntawm kev tswj lub IGBT trigger, lub mem tes dav hloov pauv tshuab siv los qhia txog kev sib haum xeeb, cov khoom siv hluav taws xob thiab cov khoom siv tam sim no nyob rau hauv qhov kev taw qhia rau lub zog xa hluav taws xob kom ua tiav cov txiaj ntsig ntawm kev tshem tawm cov kev sib haum xeeb.Cov lim dej zoo tuaj yeem tshaj li ntawm 95%, yog li txhim kho qhov kev nyab xeeb thiab kev ntseeg tau ntawm cov khoom siv hluav taws xob, thiab ua tiav lub hom phiaj ntawm kev tiv thaiv ib puag ncig, kev txuag hluav taws xob thiab kev ua haujlwm zoo.
Kev txiav txim siab txog kev tswj hwm lub tuam txhab kev siv hluav taws xob yog tus tsav tsheb tseem ceeb rau cov tuam txhab siv kev tswj hwm kev sib raug zoo.Lub tuam txhab muab hluav taws xob yuav tsum tau tsim hluav taws xob tsim nyog rau cov neeg siv khoom siv hluav taws xob.Yog li ntawd, lub tuam txhab muab hluav taws xob tau tshaj tawm cov kev tswj xyuas tam sim no rau cov neeg siv uas tuaj yeem ua paug rau daim phiaj.Raws li ntau thiab ntau lub tuam txhab xav tau lub zog zoo dua, cov tuam txhab hluav taws xob yuav muab cov kev cai nruj dua rau cov neeg siv khoom siv hluav taws xob.
Feem ntau hais lus, ib feem ntawm kev sib haum xeeb thiab kev tswj hwm kev sib haum xeeb hauv nruab nrab tuaj yeem ua ke los tsim cov kev daws teeb meem zoo.Rau harmonic qhov chaw loads nrog ntau zog (xws li intermediate zaus induction furnaces, soft starters, thiab lwm yam).), siv ultra-high voltage harmonic lim rau hauv zos harmonic tswj kom txo cov harmonic tam sim no nkag rau hauv daim phiaj fais fab.Rau kev sib cais ntawm cov khoom thauj nrog lub zog me me thiab lub zog sib faib, kev tswj hwm kev koom ua ke yuav tsum tau nqa tawm ntawm lub tsheb npav.Koj tuaj yeem siv Hongyan lub lim dej ua haujlwm lossis lim lim.
Lub refining thiab tshuaj lom neeg kev lag luam ntawm cov hlau uas tsis yog-ferrous yuav tsum tau siv cov txheej txheem ntawm electrolysis, yog li ib tug high-power rectifier yog ib qho tseem ceeb.Tib neeg siv hydrogen ntau lawm los ntawm electrolysis ntawm dej ua piv txwv.Cov neeg yuav tsum teeb tsa ib txheej ntawm rectifier transformer thiab thyristor rectifier txee.Txoj kev ballast yog rau-theem ob lub hnub qub inverted hom.Lub generated alternating tam sim no yog siv rau lub electrolytic cell: 10KV / 50HZ-rectifier transformer-theem voltage 172V * 1.732 theem voltage 2160A-rectifier txee-AC 7200A / 179V-electrolytic cell.Rectifier transformer: rau-theem ob lub hnub qub rov qab sib npaug series reactor lossis peb-theem tsib-kem rau-theem ob lub hnub qub rov qab.Input kab ntim: 1576 kVA valve sab ntim 2230 kVA hom ntim 1902 kVA thyristor rectifier txee K671-7200 A / 1179 volts (plaub tag nrho).Cov khoom siv rectifier yuav ua rau muaj ntau lub zog tam sim no, uas yuav ua rau muaj kev phom sij heev rau lub zog hluav taws xob ntawm daim phiaj hluav taws xob.
Nyob rau hauv lub high-power peb-theem puv-bridge 6-mem tes rectifier ntaus ntawv, lub siab-order harmonics generated los ntawm lub rectifier account rau 25-33% ntawm tag nrho cov high-order harmonics, uas yuav ua rau muaj kev puas tsuaj loj rau lub hwj chim daim phiaj, thiab cov yam ntxwv siab kev sib haum xeeb tsim tawm yog 6N ± 1 zaug, uas yog, lub sijhawm tus yam ntxwv ntawm lub valve sab yog 5th, 7th, 11th, 13th, 17th, 19th, 23rd, 25th, thiab lwm yam, thiab 5th thiab 7th siab dua. harmonic Cheebtsam yog generated los ntawm lub PCC taw tes nyob rau hauv loj network sab Tus yam ntxwv high-order harmonics yog nyob rau tib lub valve sab, cov uas 5th kev txiav txim loj, thiab 7th kev txiav txim txo nyob rau hauv lem.Kev ua haujlwm sib luag ntawm pawg rectifier transformer nrog theem-hloov windings tuaj yeem tsim 12 pulses, thiab cov yam ntxwv lub sijhawm ntawm lub network sab yog 11 zaug, 13 zaug, 23 zaug, 25 zaug, thiab lwm yam, thiab 11 zaug thiab 13 zaug yog qhov loj tshaj.
Yog tias tsis muaj cov cuab yeej lim tau nruab rau ntawm daim phiaj sab lossis sab valve, tag nrho cov mem tes tam sim no txhaj rau hauv daim phiaj yuav dhau ntawm kev lag luam tus qauv ntawm peb lub tuam txhab, thiab cov yam ntxwv sib haum xeeb tam sim no txhaj rau hauv lub ntsiab transformer tseem yuav tshaj qhov kev tswj hwm tus nqi. peb lub tuam txhab kev lag luam tus qauv.Kev sib raug zoo siab dua yuav ua rau cov xaim xaim hluav taws xob, hluav taws xob hloov hluav taws xob, cov khoom siv tsis raug cai tsis tuaj yeem tawm hauv lub Hoobkas, kev sib txuas lus tsis zoo, kev hloov pauv huab cua tsis zoo, lub tshuab hluav taws xob surges thiab lwm yam tsis zoo.
Feem ntau hais lus, nyob rau hauv lub zog loj zog network ntawm lub system, cov yam ntxwv siab dua harmonics yuav raug tshem tawm los ntawm kev siv passive lim (fc) li, thiab cov kev tswj cov hom phiaj yuav ua tau raws li.Nyob rau hauv cov ntaub ntawv ntawm ib tug me me hluav taws xob daim phiaj system, lub hom phiaj ntawm kev soj ntsuam nrog high-order harmonics yog siab.Ntxiv rau kev txhim kho lub peev xwm loj ntawm cov khoom siv lim dej, lub peev xwm me me ua haujlwm lim (apf) kuj tuaj yeem siv los ua kom tau txais lub zog zoo tiv thaiv kev xav tau.Rau rectifier installation systems nrog ntau txoj kev sib txuas, peb cov kws tshaj lij lim kev them nyiaj teeb tsa muaj cov hom phiaj sib txawv.Tom qab kev sim ntawm qhov chaw, lawv tuaj yeem "kho" rau cov neeg siv khoom thiab xaiv txoj kev kho mob uas haum rau qhov xwm txheej ntawm qhov chaw.
