Dynamic Voltage Regulator
Kev cuam tshuam ntawm qhov system voltage ua rau luv luv -lub sij hawm voltage poob rau sab load (ntev los ntawm ob peb mus rau kaum ob lub voj voog), uas yog thawj qhov ua rau muaj kev ua haujlwm tsis zoo hauv cov khoom rhiab, tshwj xeeb hauv cov khoom siv computer.
Khoom Description
Dynamic Voltage Restorer (DVR) txais qhov tseeb PWM interleaving technology. Nyob rau hauv cov ntaub ntawv ntawm ib tug voltage dip, lub DVR tuaj yeem them sai sai rau qhov hloov pauv voltage, kho peb -theem voltage imbalances, mitigate flicker, thiab kho qhov voltage deviations kom tswj cov zis voltage, yog li tiv thaiv loads.
Yam khoom
Online DVR-X
Cov khoom yog tsim los ntawm inverter, cais transformer, supercapacitor, SCR hloov, thiab lwm yam, nrog rau superca-pacitor muab lub zog rau daim phiaj rau kev them nyiaj. Nyob rau hauv cov ntaub ntawv ntawm ib tug voltage dip, daim phiaj voltage yuav tsum tau disconnected, tso cai rau lub supercapacitor muab lub zog rau lub load yam tsis muaj kev cuam tshuam los ntawm fluctuations nyob rau hauv daim phiaj voltage. Kev them nyiaj qhov tob tuaj yeem npog 0-130%.
Offline DVR-D
Cov khoom muaj xws li ib tug rectifier, inverter, them nyiaj transformer, thiab bypass. Lub zog them nyiaj tau los ntawm daim phiaj hluav taws xob los ntawm lub converter. Nws muaj qhov voltage dip them nyiaj qhov tob ntawm 40%, tag nrho kho qhov voltage dip, thiab zoo hais txog qhov voltage dips thiab surges, uas pab tiv thaiv kev lag luam thiab ntau lawm los ntawm voltage fluctuations rau cov neeg siv.
Daim ntawv thov Scenario
Nws yog siv rau hauv kev lag luam nrog kev ua haujlwm tas mus li, xws li chip manufacturing, automotive, pharmaceuticals, petrochemicals, tsev kho mob, fais fab nroj tsuag, khoom noj khoom haus, tshuaj fiber ntau, iav ntau lawm, cov ntaub ntawv chaw, thiab luam yeeb.
Cov cuab yeej DVR tuaj yeem ntsia tau rau hauv series ntawm cov ntaub ntawv chaw, cov servers, thiab cov khoom siv hluav taws xob los tiv thaiv cov hluav taws xob poob qis, tiv thaiv cov neeg rau zaub mov tsis ua haujlwm thiab cov ntaub ntawv poob, thiab txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm cov tshuab computer;
Lub DVR ntaus ntawv kuj tseem tuaj yeem ntsia tau rau hauv cov kab nruab nrab ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob los tiv thaiv qhov cuam tshuam ntawm qhov hluav taws xob -bances, tiv thaiv kev ua haujlwm tsis zoo hauv cov khoom siv hluav taws xob. Piv txwv li, nyob rau hauv semiconductor factories, nws tiv thaiv voltage dips thiab luv luv interruptions uas yuav ua rau kom loj nyiaj txiag poob thiab ib tug loj npaum li cas ntawm cov khoom scraped;
Rau cov ntawv thov UPS uas tsis tas yuav siv sijhawm ntev - lub sijhawm rov qab fais fab, DVR cov cuab yeej muaj peev xwm ua kom muaj zog hluav taws xob zoo dua thiab tus nqi zoo dua - kev ua tau zoo piv rau UPS systems, ua rau nws muaj txiaj ntsig zoo rau kev txhim kho qhov hluav taws xob zoo ntawm sab load.

Q&A
Lub Dynamic Voltage Restorer (DVR) ua haujlwm li cas?
Lub Dynamic Voltage Restorer (DVR) feem ntau muaj lub zog cia khoom (supercapacitor), lub inverter, hloov pauv, thiab lub voj voog hla, txuas nrog hauv cov khoom siv hluav taws xob thiab cov khoom tiv thaiv. Thaum pom tias cov khoom siv hluav taws xob sib txawv ntawm qhov ntsuas hluav taws xob, DVR tam sim ntawd disconnects cov khoom siv hluav taws xob. Nyob rau tib lub sijhawm, nws rub lub zog xav tau los ntawm nws tus kheej lub zog cia khoom, tsim lub zog txhaj tshuaj nrog tib lub zog thiab theem raws li cov kab hluav taws xob hluav taws xob los ntawm peb -theem choj inverter circuit system, yog li muab lub zog tsim nyog rau lub sijhawm luv luv.
