Lus Cim: Lub hwj chim muab rau peb los ntawm lub hwj chim kab hluav taws xob feem ntau dynamically balanced.Feem ntau, ntev npaum li qhov voltage txwv tsis pub dhau ib qho kev teev tseg, peb tuaj yeem tau txais ib puag ncig zoo dua rau kev siv hluav taws xob.Tab sis lub hwj huam mov system tsis muab lub zog zoo meej.Tsis tas li ntawd, tsis muaj txoj hauv kev rau cov tuam txhab tsim khoom los muab cov cuab yeej tiv thaiv kev tiv thaiv hluav taws xob rau txhua yam khoom siv hluav taws xob.Qhov teeb meem ntawm qhov hluav taws xob sag yuav ua rau muaj kev tsis yooj yim thiab teeb meem rau lub neej txhua hnub thiab kev tsim khoom.Yog li dab tsi zoo them cov cuab yeej muaj los txo qhov cuam tshuam ntawm voltage sags?Feem ntau, peb siv peb hom kev them nyiaj: UPS (Uninterruptible Power Supply), Solid State Transfer Switch (SSTS), thiab Dynamic Voltage Restorer (DVR-Dynamic Voltage Restorer).Los ntawm kev tso cov nyiaj them rau cov khoom siv no ntawm cov khoom siv hluav taws xob thiab cov neeg siv hluav taws xob network.Peb cov khoom siv them nyiaj no muaj lawv tus kheej qhov zoo thiab qhov tsis zoo.
Uninterruptible Power Supply (UPS—Uninterruptible Power Supply): UPS luv luv, yog cov khoom siv feem ntau siv los txo cov nqi hluav taws xob.Lub hauv paus ntsiab lus ua haujlwm ntawm UPS feem ntau yog siv lub zog tshuaj xws li roj teeb los khaws cov hluav taws xob hluav taws xob.Thaum ntsib teeb meem ntawm lub zog tsis ua hauj lwm tam sim ntawd ntawm lub tshuab hluav taws xob, UPS tuaj yeem siv lub zog khaws cia ua ntej kom tswj tau lub zog hluav taws xob rau ob peb feeb mus rau ob peb teev.Nyob rau hauv txoj kev no, qhov teeb meem voltage sag tshwm sim los ntawm lub hwj chim mov system yuav daws tau nyob rau hauv ib tug tej lub sij hawm ntawm lub sij hawm.Tab sis UPS kuj muaj nws qhov tsis muaj zog dua.Hluav taws xob yog khaws cia los ntawm cov tshuaj siv hluav taws xob, thiab qhov tsim qauv no nws tus kheej siv ntau lub zog.Lub zog cia roj teeb tsis tsuas yog siv ntau qhov chaw, tab sis kuj tseem nyuaj rau kev tswj hwm.Nyob rau tib lub sijhawm, rau cov loads uas muaj kev cuam tshuam ntau dua ntawm daim phiaj, nws yog qhov yuav tsum tau ua kom nws lub zog nce ntxiv.Txwv tsis pub, nws yooj yim ua rau lub zog cia roj teeb ua tsis tiav.
Lub Xeev Hloov Hloov Hloov Hloov (SSTS—Lub Xeev Hloov Hloov Hloov), hu ua SSTS.Nyob rau hauv cov txheej txheem ntawm industrial manufacturing factories los yog siv hluav taws xob tiag tiag los ntawm cov neeg siv.Feem ntau muaj ob qhov sib txawv busbars lossis cov kab hluav taws xob los ntawm cov chaw sib txawv rau cov khoom siv hluav taws xob.Lub sijhawm no, ib zaug ib qho ntawm cov khoom siv hluav taws xob muaj kev cuam tshuam lossis qhov hluav taws xob tsis zoo, nws tuaj yeem hloov mus rau lwm lub zog siv hluav taws xob los ntawm kev siv SSTS, yog li ua kom muaj kev txuas ntxiv ntawm tag nrho cov khoom siv hluav taws xob.Qhov tshwm sim ntawm SSTS yog tsom rau kev daws teeb meem UPS.Tsis tsuas yog tag nrho cov nqi ntawm cov cuab yeej siv peev tsawg, tab sis nws kuj yog ib qho kev daws teeb meem zoo tshaj plaws rau kev poob qis ntawm cov khoom siv hluav taws xob siab.Piv nrog UPS, SSTS kuj muaj ntau yam zoo xws li tus nqi qis, hneev taw me me, thiab kev tu-dawb.Qhov tsuas yog qhov tsis zoo yog qhov thib ob busbar lossis cov kab lag luam los ntawm cov chaw sib txawv yuav tsum muaj rau cov khoom siv hluav taws xob, uas yog, yuav tsum muaj cov khoom siv hluav taws xob rov qab.
Dynamic Voltage Restorer (DVR—Dynamic Voltage Restorer), hu ua DVR.Feem ntau, nws yuav raug ntsia nruab nrab ntawm cov khoom siv hluav taws xob thiab cov khoom siv thauj khoom.Lub DVR tuaj yeem them nyiaj rau sab load rau qhov tsim nyog poob voltage nyob rau hauv milliseconds, rov qab load sab mus rau qhov qub voltage, thiab tshem tawm qhov cuam tshuam ntawm voltage sag.Lub luag haujlwm tseem ceeb tshaj plaws ntawm DVR yog muab lub sijhawm teb sai txaus, thiab nws tuaj yeem ua rau kom qhov tob ntawm kev tiv thaiv hluav taws xob sag.Qhov kev tiv thaiv qhov tob tuaj yeem txhais tau raws li qhov ntau ntawm qhov hluav taws xob sag uas DVR tuaj yeem haum.Tshwj xeeb tshaj yog rau cov neeg siv lub Hoobkas, feem ntau hais lus, ib zaug muaj qhov hloov pauv ntawm qhov hluav taws xob sag thaum lub sijhawm ua haujlwm ntawm lub tshuab thiab khoom siv, nws yuav yooj yim ua rau muaj teeb meem hauv kev ua tiav ntawm cov khoom lag luam, uas yog, yuav muaj cov khoom tsis raug.Los ntawm kev siv DVR, qhov kev ua haujlwm ib txwm ua ntawm lub Hoobkas tuaj yeem lav tau, thiab qhov cuam tshuam los ntawm qhov tsis tshua muaj hluav taws xob hloov pauv tsis tuaj yeem xav tau.Tab sis lub DVR tsis muaj txoj hauv kev los them nqi hluav taws xob cuam tshuam ntau tshaj qhov voltage sag tiv thaiv qhov tob.Yog li ntawd, thaum qhov hluav taws xob poob nyob rau hauv qhov ntau ntawm qhov voltage sag tiv thaiv qhov tob, lub DVR tsuas tuaj yeem ua nws lub luag haujlwm vim nws tau lees tias tsis muaj kev cuam tshuam.
Lub DVR tsim los ntawm Hongyan Electric muaj kev ntseeg tau zoo heev: kev ntseeg siab, tshwj xeeb tshaj yog tsim rau cov khoom lag luam, kev ua haujlwm siab, cov lus teb ceev ceev, kev ua haujlwm zoo tshaj plaws, tsis muaj kev sib raug zoo, kev tswj hwm digital tag nrho raws li DSP, txhim khu kev qha kev ua haujlwm siab, kev sib txuas ua ke siab. muaj nuj nqi, modular tsim, multi-function vaj huam sib luag nrog graphic TFT tseeb xim zaub, kiag li tu-dawb, tsis tshua muaj nqi khiav hauj lwm, tsis xav tau rau cov khoom cua txias, compact qauv tsim, me me hneev taw thiab ntau lwm yam zoo.
