Kev ua haujlwm ntawm cov khoom siv rectifier rau electrolysis, electroplating, thiab metallurgy generates tseem ceeb harmonics; 12-, 24-, thiab 36-pulse rectifier transformers sawv cev rau cov kev daws teeb meem loj. Cov pulse configurations txawv heev nyob rau hauv cov nqe lus ntawm harmonic supposed, tus nqi yuav khoom, nqi hluav taws xob, thiab cov peev uas yuav tsum tau rau cov khoom pab. Cov tuam txhab xws li Henan Xintailong tuaj yeem phim cov qauv mem tes tshwj xeeb rau ntawm qhov chaw hauv kab sib chaws, sib npaug pib peev tiv thaiv cov nqi khiav haujlwm mus sij hawm ntev.
I. Cov yam ntxwv tseem ceeb ntawm Peb Pulse Configurations
1. 12-Pulse
Qhov kev teeb tsa no tshem tawm tsuas yog 5th thiab 7th (tsawg- xaj) harmonics, tawm hauv 11th thiab 13th harmonics tam sim no, ua rau muaj cov ntsiab lus sib haum xeeb hauv daim phiaj. Lub transformer nta ib qho yooj yim qauv nrog ncaj winding thiab cov qauv tsim, muab tus nqi qis tshaj plaws thiab kev nqis peev tsawg tshaj plaws hauv cov khoom siv lim dej. Nws qhov tsis zoo suav nrog kev poob qis dua kev sib raug zoo thaum lub sijhawm ua haujlwm ntev - thiab nyiam qhov cuam tshuam ntawm qhov hluav taws xob ntawm daim phiaj sab. Nws yog qhov tsim nyog rau qis- rau- cov kab hluav taws xob nruab nrab uas ua haujlwm tsis tu ncua thiab tsis raug rau cov kev txwv nruj me ntsis ntawm cov kab hluav taws xob cog.
2. 24-Pulse
Qhov kev teeb tsa no tau tshem tawm 5th, 7th, 11th, thiab 13th harmonics, tawm tsuas yog qhov tsawg kawg nkaus siab -txoj kev sib haum xeeb thiab muab kev sib haum xeeb me ntsis. Cov khoom siv tus nqi yuav poob ntawm 12-pulse thiab 36{10}}pulse qauv. Nws tsis tas yuav muaj peev xwm lim cov khoom siv loj thiab yog ib qho kev xaiv rau cov khoom siv hluav taws xob siab, cov kab ntau lawm. Harmonic poob raug txo qis, ua rau pom kev txuag hluav taws xob txhua xyoo; nws muaj qhov sib npaug ntawm kev nqis peev thiab kev ua haujlwm rov qab los, ua rau nws tsim nyog rau feem ntau ntawm 24-teev nruam electrolysis thiab electroplating ua haujlwm.
3. 36-Pulse
Tsawg-kev txiav txim harmonics raug tshem tawm zoo, ua rau lub voj voog sib luag thiab muaj kuab paug tsawg tsawg. Lub transformer nta ib tug complex winding qauv yuav tsum tau ntau txheej ntawm theem- hloov windings; kev tsim khoom yuav tsum nruj, uas ua rau tus nqi siab tshaj plaws pib. Nws qhov zoo muaj xws li qhov tseeb tias nws tsis tshua xav tau cov tshuab lim dej ntxiv thiab ua raws li cov qauv kev sib haum xeeb nruj, ua rau nws zoo tagnrho rau siab - zog, siab - precision hlau electrolysis tej yaam num, nrog rau cov xwm txheej uas muaj peev xwm tsis muaj kab sib chaws los yog ib puag ncig kev ua raws cai.
II. Kev xaiv raws li tus nqi-Kev ua tau zoo thiab daim ntawv thov scenario
Xaiv 12-pulse kom tau txais txiaj ntsig zoo dua
1. Cov khoom siv hluav taws xob tsawg dua lossis sib npaug ntawm 1000 kVA; tsis tu ncua ntau lawm nrog kev ua haujlwm txhua hnub hauv 6 teev;
2. Cov kab sib chaws hauv zos muaj cov kev cai sib haum xeeb; tsis muaj qhov yuav tsum tau ua kom muaj kev sib haum xeeb;
3. luv- lub sij hawm / ib ntus cov kab ntau lawm los yog sim rectifier units nrog lub neej ua haujlwm qis dua 3 xyoos;
4. Kev siv nyiaj tsawg; tsis kam nqis peev ntxiv rau hauv complex multi-winding transformers.
Xaiv 24-pulse rau qhov zoo tshaj plaws tag nrho cov nqi-kev ua tau zoo
1. Lub zog ntsuas ntawm 1000-5000 kVA; 24-teev kev ua haujlwm tsis tu ncua rau electroplating lossis dav hlau electrolysis;
2. Daim phiaj muaj cov kev txwv kev sib haum xeeb tab sis tsis tas yuav xoom- cov zis tawm txawv txav;
3. Kev npaj ntev- siv sijhawm (ntau tshaj 8 xyoo); lub siab xav txo qis kev sib raug zoo thiab txuag cov nqi hluav taws xob;
4. Xav kom muaj kev sib haum xeeb txo qis kev ua tau zoo tshaj 12-pulse systems tsis muaj tus nqi yuav khoom siab ntawm 36-pulse systems.
Xaiv 36-pulse kom ntev dua- lub sij hawm siv nyiaj
1. Ib qho -unit zog> 5000 kVA; loj - nplai electrolytic aluminium lossis tsawg hlau refining ntau lawm kab;
2. Txwv cog daim phiaj muaj peev xwm; ntau harmonics yuav ua rau hnyav nplua;
3. Cov txheej txheem hauv qab yuav tsum muaj qhov siab tshaj DC voltage precision; waveform fluctuations tsis kam;
4. Project lifecycle tshaj 15 xyoo; kev txaus siab los ua kom muaj kev nqis peev ntau dua kom tsis txhob muaj cov nqi ntawm kev yuav khoom thiab tswj xyuas cov khoom siv lim cais.
III. Tag Nrho -Lifecycle Cost Comparison Logic
1. Tus Nqi Muag Khoom: 12-pulse < 24-pulse < 36-pulse. Kev suav cov mem tes ntau dua yuav tsum tau hloov cov theem hloov ntau dua, ua rau muaj kev nce ntxiv hauv cov khoom siv thiab cov nqi tsim khoom.
2. Tus Nqi Zog: 12-Pulse systems tau txais kev poob siab tshaj plaws thiab cov nqi hluav taws xob txhua xyoo; poob poob ntau nrog 24-pulse systems; 36-pulse systems muaj qhov qis tshaj qhov kev sib raug zoo ntxiv, muab cov txiaj ntsig zoo txuag hluav taws xob thaum lub sijhawm ua haujlwm ntev.
3. Tus nqi txo qis: 12-pulse systems feem ntau xav tau cov tshuab lim dej ntxiv, ua kom cov kev tu ncua ntev; 24-pulse systems tuaj yeem siv cov ntxaij lim dej me me; 36-pulse systems feem ntau tsis tas yuav muaj kev sib haum xeeb ntxiv rau hauv cov xwm txheej feem ntau.
4. Tus Nqi Kho Mob: 12-Pulse systems muaj kev sib raug zoo ntawm kev vibration, ua rau muaj kev laus sai ntawm windings thiab keyboards thiab xav tau kev pab ntau zaus; 24-pulse thiab 36-pulse systems ua haujlwm zoo dua thiab muaj qhov ua haujlwm qis dua.
Cov ntsiab lus
Rau cov ntawv thov ua ntej pib tus nqi qis thiab tsis sib xws, lub teeb -load haujlwm, 12-pulse system yog qhov kev xaiv zoo tshaj. Rau feem coob ntawm cov qauv, siab - fais fab kev lag luam rectification scenarios, 24-pulse system muab qhov zoo tshaj plaws tag nrho tus nqi los ntawm kev ntsuas tus nqi nrog kev siv zog. Rau qhov loj - nplai, siab{10}} cov haujlwm fais fab uas muaj cov kev cai nruj nruj thiab kev tsim khoom mus sij hawm ntev, 36-pulse system ua pov thawj ntau tus nqi-zoo nyob rau lub sijhawm ntev vim qhov kev poob qis thiab kev tshem tawm ntawm qhov xav tau rau cov khoom siv txo qis kev sib haum xeeb. Kev txiav txim siab xaiv yuav tsum tsis yog raws li tus nqi pib ntawm cov cuab yeej siv xwb tab sis yuav tsum coj mus rau hauv tus account xws li cov sijhawm ua haujlwm ntau lawm, cov qauv kab sib chaws, thiab qhov project lub neej kev pabcuam.
