Uninterruptible Power Supply (UPS) systems yog qhov tseem ceeb hauv kev tswj xyuas lub zog txuas mus ntxiv rau cov tshuab tseem ceeb thaum lub hwj chim tawm. Hauv plawv ntawm cov tshuab no yog cov roj teeb uas khaws lub zog tsim nyog. Nkag siab txog ntau hom UPS roj teeb yog qhov tseem ceeb rau kev xaiv qhov kev xaiv zoo tshaj plaws

Thaum nws los txog rau kev xaiv lub roj teeb uas haum rau koj cov kev xav tau, nkag siab qhov sib txawv ntawm cov roj teeb lithium, tshwj xeeb tshaj yog LiFePO4, thiab cov roj lead-acid yog qhov tseem ceeb. Lawv cov yam ntxwv sib txawv ua rau lawv haum rau cov xwm txheej sib txawv. Qhov tseem ceeb sib pivRated Peev Xwm thiab Cycle LifeLithi

Lead-acid roj teeb tau ua lub hauv paus hauv lub zog cia khoom siv txij li lawv tsim nyob rau hauv nruab nrab-19th caug xyoo. Cov khoom siv hluav taws xob txhim khu kev qha no tau siv dav hauv ntau daim ntawv thov. To taub yuav ua li cas lead-acid roj teeb ua hauj lwm yog ib qho tseem ceeb rau optimizing lawv kev ua tau zoo thiab ncua lawv l

Roj teeb vulcanization, tseem hu ua sulfation, yog ib qho teeb meem tshwm sim uas cuam tshuam rau cov roj ntsha lead-acid, ua rau txo qis kev ua haujlwm thiab lub neej luv luv. Kev nkag siab txog cov laj thawj thiab kev siv cov kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb rau kev tswj xyuas kev noj qab haus huv thiab kev ua neej ntev ntawm cov roj ntsha lead-acid.Kuv

Txhawm rau nkag siab cov nuances ntawm kev tiv thaiv sab hauv thiab impedance, nws yog ib qho tseem ceeb kom paub tias impedance cuam tshuam rau AC (alternating tam sim no), thaum lub zog sab hauv muaj feem cuam tshuam nrog DC (direct tam sim no).
