Los ntawm chav kawm physics peb paub tias lub tshuab hluav taws xob kuj tuaj yeem ua haujlwm raws li lub tshuab hluav taws xob; cov nyhuv no yog siv los rov qab hluav taws xob. Yog tias peb muaj ib yam dab tsi loj uas tau tsav los ntawm lub tshuab hluav taws xob, tom qab ntawd thaum braking, lub zog txhua yam tuaj yeem hloov mus rau hauv hluav taws xob hluav taws xob thiab xa rov qab rau hauv qhov system. Txoj hauv kev no tau nquag siv hauv kev lag luam thiab kev thauj mus los: nws txo qis kev siv hluav taws xob, tab sis tsis zoo sib xws nrog cov khoom siv hluav taws xob tsis cuam tshuam. Nyob rau hauv ib tug recuperative system lawv yuav tsum tau siv nrog zoo saib xyuas.
Thaum twg rov tsim dua tshiab ntsib nrog UPS?
Qhov teeb meem tshwm sim nrog qee hom kev lag luam thauj khoom, feem ntau cov no yog qee yam ntawm cov cuab yeej siv tshuab lossis lwm yam khoom siv uas tau tsav. Lawv yog tswj los ntawm qhov hu ua zaus converters los yog servos, uas yog qhov tseem ceeb kuj zaus converters nrog tawm tswv yim. Thaum lub cav ntawm qhov kev teeb tsa no tsis muaj zog lawm, nws tuaj yeem hloov mus rau lub tshuab hluav taws xob, pib tsim hluav taws xob thaum lub sijhawm braking thiab muab nws mus rau lub tswv yim network.
Niaj hnub nimno industrial regenerative installation yog feem ntau tiv thaiv lub hwj chim tsis ua hauj lwm siv ib tug UPS. Piv txwv li, peb tuaj yeem xav txog CNC tshuab siv rau kev ua haujlwm siab ntawm cov khoom kim heev. Lub voj voog thev naus laus zis yuav tsum ua kom tiav kom raug, thiab yog tias cov txheej txheem cuam tshuam, nws yuav tsis tuaj yeem rov qab tau thiab cov khoom ua haujlwm yuav tsum tau muab pov tseg. Nws tuaj yeem raug nqi ntau dua ib lab rubles, yog tias peb tham txog kev tsim kho tshuab, kev tsim nkoj thiab kev tsim dav hlau, nrog rau kev ua tub rog thiab chaw siv tshuab.
Vim li cas UPSs tsis sib haum nrog kev rov zoo?
Lub zaus converter hla cov hluav taws xob generated thiab outputs nws mus rau lub tswv yim. Nyob rau hauv rooj plaub no, lub zog tswj kev tswj hwm yuav tsum tau pib xav tias muaj peev xwm rov qab tau lub zog rau lub network kom tau txais txiaj ntsig zoo. Cov txheej txheem zoo li no tau ua tib zoo xam thiab raug nqi ntau dua, tab sis nws tso cai rau koj txo cov nqi hluav taws xob thiab tsis txhob muaj xwm txheej. Yog tias ob peb qhov kev tiv thaiv UPS ua haujlwm ib txhij, lub zog tsim los ntawm ib qho ntawm lawv tuaj yeem siv los ntawm cov neeg nyob sib ze. Yog tias muaj teeb meem nrog kev tswj hwm kev thauj khoom thiab kev suav, lossis tsuas yog ib chav ua haujlwm hauv lub kaw lus, kev rov ua haujlwm dua yuav cuam tshuam rau UPS. Cov cuab yeej ua tau raws li cov txheej txheem classical tsuas yog tsis tsim rau qhov no: lub zog dhau los ntawm lub inverter, uas pib ua lub luag haujlwm ntawm ib hom kev txhawb zog, uas ua rau muaj qhov nce ntawm qhov hluav taws xob ntawm lub tsheb npav DC. Yuav luag tsis muaj UPS niaj hnub no muaj peev xwm daws tau qhov teeb meem no; tom qab kev tiv thaiv tau tshwm sim, nws yuav hloov mus rau hom bypass.
Yuav tawm mus qhov twg?
Txhawm rau tiv thaiv lub zaus hloov pauv los ntawm kev tawg, los ntawm qhov uas lub zog tsim los ntawm kev teeb tsa thaum lub sij hawm rov qab mus rau hauv lub cev, tshwj xeeb modules nrog braking resistors raug ntsia. Lawv suav nrog hauv Circuit Court thaum lub sijhawm, dissipate lub zog ntau dhau ntawm cov cua sov thiab, ntxiv rau cov khoom siv, kuj tseem tiv thaiv UPS. Qhov teeb meem, peb rov hais dua, yog daws tau nyob rau theem tsim ntawm cov txheej txheem thev naus laus zis: kev thauj khoom thiab kev tswj hwm lub zog yuav tsum raug teeb tsa kom raug. Koj tseem tuaj yeem txuas ob peb lub UPS nyob rau tib lub sijhawm rau ib qho khoom me me - qhov no, qhov kev rov qab los yog "tawg" los ntawm lub zog thiab nws yuav tsis muaj peev xwm ua rau lub zog tsis cuam tshuam.
