Nyob rau theem no, cov khoom siv hluav taws xob faib hluav taws xob thiab cov khoom siv hluav taws xob thiab kev faib hluav taws xob hauv kev lag luam petrochemical feem ntau siv lub zog AC ntawm UPS fais fab mov system.Tom qab ntau ceg raug tswj thiab ua tiav los ntawm cov hluav taws xob qis hluav taws xob, lawv tso tawm 24V DC thiab 110V AC los ntawm AC / DC converters lossis transformers thiab lwm yam khoom siv los muab cov khoom siv hluav taws xob rau cov khoom sib txuas.
Lub switchboard (lub thawv) ntsia rau hauv kev lag luam petrochemical yuav tsum tau nruab rau hauv tsev nrog ib puag ncig zoo.Yog tias yuav tsum muaj kev teeb tsa sab nraum zoov, thaj chaw uas muaj qhov hnyav hnyav yuav tsum tau zam, thiab cov thawv xa khoom (cov thawv) tsim nyog rau cov qauv ib puag ncig ntawm qhov chaw teeb tsa yuav tsum raug xaiv.
Vim qhov kev xav tau ntawm kev tsim khoom, muaj ntau lub twj tso kua mis loads hauv kev lag luam petrochemical, thiab ntau lub twj tso kua mis yog nruab nrog cov pib muag muag.Kev siv cov pib muag muag ntxiv ua rau cov ntsiab lus tam sim no ntawm cov khoom siv hluav taws xob faib hluav taws xob hauv kev lag luam petrochemical.Tam sim no, cov pib muag muag feem ntau siv 6 ib leeg-pulse rectifiers los hloov AC tam sim no rau hauv DC, thiab cov kev sib haum xeeb tshwm sim feem ntau yog 5th, 7th thiab 11th harmonics.Kev puas tsuaj ntawm kev sib haum xeeb hauv petrochemical system software tshwj xeeb yog tshwm sim hauv kev puas tsuaj rau hluav taws xob engineering thiab kev ua yuam kev ntawm kev ntsuas raug.Kev tshawb fawb tshawb fawb qhia tau hais tias kev sib haum xeeb tam sim no yuav ua rau poob ntxiv rau cov hloov pauv, uas tuaj yeem ua rau overheating, ua rau cov laus ntawm cov ntaub ntawv insulating thiab ua rau cov rwb thaiv tsev puas.Lub xub ntiag ntawm pulse tam sim no yuav ua rau kom pom tseeb lub zog thiab muaj kev cuam tshuam tsis zoo rau kev ua haujlwm ntawm lub transformer.Nyob rau tib lub sijhawm, harmonics ncaj qha cuam tshuam tsis zoo rau cov capacitors, Circuit Court breakers, thiab cov khoom siv tiv thaiv relay hauv lub zog hluav taws xob.Rau ntau cov cuab yeej ntsuas, lub hauv paus tiag tiag txhais tau tias square tus nqi ntsuas tsis tuaj yeem ntsuas, tab sis qhov nruab nrab tus nqi ntsuas tau, thiab tom qab ntawd qhov kev xav waveform yog sib npaug los ntawm qhov ntsuas qhov zoo kom tau txais tus nqi nyeem ntawv.Thaum cov kev sib haum xeeb loj heev, cov kev nyeem ntawv no yuav muaj qhov sib txawv loj, ua rau kev ntsuas qhov sib txawv.
Tej zaum koj yuav ntsib teeb meem?
1. Pib teeb meem ntawm ntau yam blowers thiab twj
2. Lub zaus converter tsim ib tug loj tus naj npawb ntawm harmonics, uas cuam tshuam rau kev ruaj ntseg ntawm cov khoom siv hluav taws xob nyob rau hauv lub system.
3. Kev nplua nyiaj tsis raug los ntawm qhov tsis zoo ntawm lub zog hluav taws xob (raws li "Power Factor Adjustment Electricity Fee Measures" tsim los ntawm Ministry of Water Resources thiab Hluav Taws Xob ntawm peb lub tuam txhab thiab Lub Tuam Txhab Nqe ntawm peb lub tuam txhab).
4. Kev lag luam petrochemical yog lub tuam txhab siv hluav taws xob siab.Vim muaj kev hloov pauv hauv peb lub tuam txhab txoj cai siv hluav taws xob thiab cov cai, nws yuav raug cuam tshuam los ntawm qhov sib txawv ntawm cov nqi hluav taws xob.
Peb qhov kev daws teeb meem:
1. Txhim kho hy-hom high-voltage reactive fais fab tsis siv neeg them nyiaj rau ntawm 6kV, 10kV lossis 35kV sab ntawm lub kaw lus kom them nyiaj rau lub zog reactive, txhim kho lub zog zoo, tsim kom muaj txiaj ntsig zoo, thiab ib feem ntawm kev tswj cov mem tes tam sim no;
2. Lub siab-voltage sab ntawm lub kaw lus siv lub zog zoo dynamic rov qab system kom dynamically compensate reactive loads nyob rau hauv lub sij hawm thiab tswj kev ntseeg tau ntawm lub hwj chim zoo ntawm lub system;
3. Lub tshuab lim dej Hongyan APF tau nruab rau ntawm qhov hluav taws xob qis 0.4kV sab los tswj cov kab ke kev sib haum xeeb, thiab cov khoom siv kev nyab xeeb zoo li qub yog siv los them cov hluav taws xob reactive ntawm lub kaw lus txhawm rau txhim kho lub zog zoo.
