Nyob rau hauv kev teb rau daim ntawv thov thiab kev loj hlob ntawm kev siv technology tshiab hauv kev tsheb ciav hlau, Suav cov tswv hauv zej zog twb tau txiav txim siab yuav ua li cas los tsim txoj hauv kev tshiab ntawm kev ua haujlwm ntse thiab kev saib xyuas kev tsheb ciav hlau kom muaj kev nyab xeeb, ntsuab, txhim khu kev qha, kev ua haujlwm siab, thiab qis. -Cov nqi khiav lag luam hauv nroog pej xeem kev thauj mus los.
Hluav taws xob cov tsheb ciav hlau ceev ceev: siv lub zog hluav taws xob ntawm lub zog hluav taws xob, hloov lub zog hluav taws xob mus rau hauv lub zog hluav taws xob, thiab ua kom cov offset.Lub zog hluav taws xob teeb pom kev zoo hluav taws xob muab lub zog rau ntau yam teeb pom kev zoo, escalators, blowers, twj thiab lwm yam khoom siv hluav taws xob hauv cov chaw nres tsheb thiab cov ntu, nrog rau lub zog rau kev sib txuas lus, teeb liab, automation thiab lwm yam khoom siv.Lub zog hloov hluav taws xob ntawm lub zog hluav taws xob engineering teeb pom kev zoo suav nrog cov chaw nres tsheb ntshav siab txo qis thiab lub zog hluav taws xob engineering teeb pom kev zoo thiab cov khoom siv teeb pom kev zoo.
Cov lus piav qhia lub zog hluav taws xob tau piav qhia meej los ntawm qhov kev xav ntawm qhov chaw sab hauv tsev, uas muaj ntau cov khoom siv hluav taws xob nyob hauv txhua qhov chaw faib khoom.AC thiab DC tuaj yeem faib cov khoom siv hluav taws xob rau hauv AC system thiab DC system.
Harmonics nyob rau hauv nroog tsheb ciav hlau feem ntau yog los ntawm traction siv fais fab mov rectifier inverter chav tsev, ua raws li ib tug tag nrho ntawm DC fais fab mov units, teeb pom kev zoo, elevator, saib, cua txias, kav dej thiab lwm yam khoom siv.Cov kev sib haum xeeb tseem ceeb yog 5th, 7th, 11th thiab 13th harmonics, nrog rau qee qhov kev sib haum xeeb thib 3.Ineffective reserves nyob rau hauv qhov kev txiav txim siab harmonic noj system nce kab poob, cuam tshuam rau kev txhim khu kev qha kev lag luam ntawm relay tiv thaiv thiab tsis siv neeg controllers, thiab txo cov kev ruaj ntseg ntawm cov khoom siv hluav taws xob siv, yog li tsim electromagnetic cuam tshuam nyob rau hauv kev sib txuas lus thiab teeb liab.Harmonics kuj tuaj yeem muaj kev puas tsuaj rau lwm cov khoom siv hluav taws xob reactive hauv kab.Nyob rau tib lub sijhawm, cov khoom siv hluav taws xob reactive yuav ua rau kom muaj kev sib haum xeeb, tsim lub voj voog vicious.
Tus neeg siv tus nqi ntawm Harmonic Kev Tswj Xyuas
Kev tsheb ciav hlau hauv nroog, tshwj xeeb tshaj yog cov khoom siv hluav taws xob thiab kev faib hluav taws xob ntawm cov chaw nres tsheb hauv subway, yuav tsum muaj kev ntseeg siab ntawm cov khoom siv hluav taws xob nruj heev.Pulse tam sim no yog qhov tseem ceeb ntawm kev hem thawj rau kev ntseeg siab ntawm nws cov khoom siv hluav taws xob.Daim ntawv thov ntawm cov ntxaij lim dej muaj peev xwm tswj tau cov kev sib raug zoo, txo qhov kev puas tsuaj ntawm kev sib haum xeeb rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm kev tsheb ciav hlau hauv nroog.Nyob rau tib lub sijhawm, tom qab lub lim dej sib haum xeeb, qhov kev sib haum xeeb ntawm lub kaw lus raug txo, thiab cov khoom siv hluav taws xob qub tuaj yeem siv tau ib txwm, ntxiv kom txo qis qhov system poob.
Tej zaum koj yuav ntsib teeb meem?
1. Cov khoom siv hluav taws xob tsawg, thiab cov khoom siv hluav taws xob siv hluav taws xob tsis tuaj yeem muab tso rau hauv kev ua haujlwm lossis feem ntau puas lawm;
2. Load hloov
3. Qhov kev hloov pauv siab ntawm kev sib haum xeeb tam sim no cuam tshuam rau kev ua haujlwm txhim khu kev qha ntawm kev tiv thaiv relay thiab cov khoom siv tswj tsis siv neeg;
4. Peb-theem kev tsis sib haum xeeb hauv Is Taws Nem hauv cov khoom siv hluav taws xob yog qhov hnyav.
Peb qhov kev daws teeb meem:
1. Txhawm rau txo cov ntsiab lus ntawm kev txiav txim siab siab, ib qho khoom siv lim tau teeb tsa rau ntawm 400V theem nrab tsheb npav ntawm cov kauj ruam-down substation rau lim.
2. Txais yuav daim ntawv dynamic ntawm Hongyan series dynamic reactive fais fab generators los muab reactive zog rau txhua theem ntawm lub system thiab tswj cov harmonics ntawm lub system nyob rau tib lub sij hawm.
3. Xaiv Hongyan dynamic kev nyab xeeb cov khoom siv, zoo tsim capacitor thiab series reactor tsis raws li cov mem tes tam sim no ntawm lub cev, txhim kho lub zog los ntawm reactive zog them, thiab txhim kho lub hwj chim zoo ntawm lub nroog rail fais fab mov thiab tis system.
4. Hongyan's dynamic kev nyab xeeb nyiaj them cov cuab yeej siv cov kev them nyiaj hybrid ntawm peb-theem sib cais nyiaj thiab peb-theem co-compensation, thiab txiav txim siab cov nyiaj them yuav tsum tau ntawm peb-theem unbalance ntawm software system.
