Yuav ua li cas UPS cov tshuab SafeGuard tseem ceeb los ntawm lub hwj chim Surges
Feb 12, 2025| Uninterruptible zog mov (UPS) cov tshuab yog cov khoom tseem ceeb uas muab lub zog thaub qab rau cov khoom cuam tshuam thaum muaj kev cuam tshuam fais fab tuag. Txawm li cas los xij, lawv lub luag haujlwm mus dhau tsuas yog muab lub zog thaum muaj kev tawm tsam; Lawv kuj tiv thaiv cov khoom siv rhiab los ntawm cov hwj chim surges. Lub zog surges tuaj yeem ua puas cov khoom siv hluav taws xob thiab ua rau cov ntaub ntawv poob, ua kom pom kev tiv thaiv ib qho tseem ceeb ntawm kev nce qib. Cov ntawv no tshawb nrhiav li cas cov tshuab Safeguard tseem ceeb, sib txawv ntawm cov kev tiv thaiv kev ntxhov siab, thiab vim li cas xaiv txoj cai nce yog qhov tseem ceeb.
Lub zog muaj hwj chim yog dab tsi?
Lub zog sib tsoo, tseem hu ua qhov hluav taws xob ntau, tshwm sim thaum theem voltage nyob rau hauv lub hluav taws xob hluav taws xob cia li nce dhau nws qib. Cov surges no tuaj yeem tshwm sim los ntawm ntau yam, xws li xob laim, cov phiaj xwm hluav taws xob hloov, lossis cov khoom siv hluav taws xob. Qhov kev tawm ntawm feem ntau kav tsuas yog ib feem ntawm ob, tab sis qhov cuam tshuam rau cov khoom siv rhiab tuaj yeem hnyav.
Kev nce qib tuaj yeem ua rau cov hluav taws xob ua rau cov hluav taws xob los ntawm kev kub ntxhov los ntawm kev kub siab, hlawv tawm ntawm cov hluav taws xob, lossis ua rau tsis ua haujlwm tas li. Nws kuj tseem tuaj yeem txo lub neej ntawm cov khoom siv hluav taws xob thiab cov peev xwm ua rau cov ntaub ntawv kev noj nyiaj txiag lossis poob hauv cov khoom siv xws li khoos phis tawj, servers, thiab cov tshuab cia. Muab cov kev cuam tshuam muaj peev xwm, tiv thaiv cov kev puas tsuaj ntawd yog vim li cas los ntawm kev siv cov tshuab uas cov khoom siv nyob rau hauv qhov chaw thiab cov ntaub ntawv kev ncaj ncees yog qhov tseem ceeb.
Yuav ua li cas UPS tshuab tiv thaiv rau lub zog hluav taws xob?
UPS cov tshuab yog tsim los muab cov hluav taws xob txuas ntxiv, ruaj khov rau cov khoom sib txuas thaum ob lub zog hluav taws xob thiab cov hluav taws xob hloov pauv. Lawv tau nruab nrog kev tiv thaiv surge cov nta uas pab txo cov kev cuam tshuam ntawm lub zog ntawm lub zog.
Kev muaj zog txias thiab kev cai
UPS Cov Txiaj Ntsig Lub Zog Tuaj Los Ntawm Lim Tawm Suab nrov thiab du hloov pauv. Qhov no yog qhov tseem ceeb tshwj xeeb rau ib cheeb tsam uas cov khoom siv hluav taws xob tsis zoo tuaj yeem tsis raug cai. Ntxiv rau kev muab hwj huam rov qab thaum lub sijhawm muaj kev txhawb nqa, nce mus ib txwm tswj cov hluav taws xob tsis tu ncua, ua kom muaj kev tswj hwm tam sim ntawd lossis dips tau mus cuag cov khoom siv sib txuas.
Surge Tiv Thaiv Mechanism
Ntau cov tshuab hluav taws xob niaj hnub tuaj nrog kev tiv thaiv kev tiv thaiv kev tiv thaiv, uas ua raws li thawj kab ntawm kev tiv thaiv tawm tsam voltage spikes. Cov kws tiv thaiv cov txheej txheem no tsim los nqus kom nqus tau ntau tshaj voltage thiab dissipate nws nyab xeeb. Thaum qhov kev soj ntsuam yog kuaj pom, cov UPS tau dhau los ua qhov hluav taws xob ntxiv kom deb ntawm cov khoom sib txuas, tiv thaiv cov khoom sib txuas los ntawm kev puas tsuaj.
Tus neeg tiv thaiv cov haujlwm ua haujlwm los ntawm kev siv cov Cheebtsam xws li hlau oxide varistors (mov), uas hloov pauv lawv cov lus teb rau ntau heev voltage. Thaum lub voltage nce siab tshaj ib qho kev pib, cov txav pauv qhov ntau dhau mus rau hauv av, tiv thaiv nws kom tsis txhob tuaj txog cov khoom siv.
Roj teeb backup thiab inverter technology
Thaum lub sij hawm tawg, cov UPS system tuaj yeem hloov mus rau nws lub roj teeb hauv lub roj teeb yuav luag tam sim ntawd, kom cov khoom siv tseem muaj zog thaum lub caij nyoog dhau los. Qhov no dual-nqis peev-voltage cov kev cai sib txuas nrog kev hloov pauv sai rau cov roj teeb hluav taws xob thiab ruaj khov raws li kev ua haujlwm zoo.
Teb lub sijhawm thiab kev kuaj pomQhov kev ua tau zoo ntawm cov nyiaj nce siab hauv kev tiv thaiv kev tiv thaiv cov hwj chim ntawm lub sijhawm nyob ntawm nws lub sijhawm teb. Khawb cov tshuab ua tau zoo tuaj yeem tshawb pom cov hluav taws xob tsis ntev hauv ib feem ob thiab koom nrog kev tiv thaiv kev tiv thaiv kev puas tsuaj ua ntej muaj kev puas tsuaj. Qhov nrawm dua ntawm UPS reacts, qhov kev tiv thaiv zoo dua.
Surge Kev Txhim Kho thiab Clamping
Surge Kev Ua Haujlwm yog lwm txoj haujlwm tseem ceeb ntawm UPS cov tshuab. Los ntawm kev nqus thiab clamping lub voltage rau qib kev nyab xeeb, cov UPS tiv thaiv cov khoom siv los ntawm kev paub kev puas tsuaj spikes. Qhov kev tiv thaiv no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau hauv cov cheeb tsam uas muaj cov roj teeb tsis ruaj khov lossis tsis khov fais fab.
Dab tsi ntawm UPS cov tshuab muab cov kev tiv thaiv ncaj qha?
Ntau hom UPS cov tshuab muaj cov theem sib txawv ntawm kev tiv thaiv tawg. Cov thawj hom ntawm cov tshuab nce yog:
Offline (standby) ups
Hom kev hloov kho no muaj cov kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev ntxhov siab thiab cov roj teeb thaub qab. Thaum nws muab kev tiv thaiv tiv thaiv cov hwj chim surges, nws yuav tsis zoo rau cov xwm txheej siab. Nws yog qhov zoo tagnrho rau cov chaw haujlwm hauv tsev lossis teeb tsa me me uas tsis tas yuav tsum muaj zog txuas ntxiv.
Txoj kev sib tham sib
Cov kev sib cuam tshuam sib txuas cov khoom siv sib cuam tshuam sib txuas cov tshuab muab qib siab dua ntawm kev tiv thaiv kev ntxhov siab dua li cov qauv standby. Lawv tswj voltage dhau los ntawm tsis siv neeg voltage kev tswj (AVR), kho kom haum rau kev hloov pauv hauv voltage. Cov kab ke no yog feem ntau siv nyob rau hauv ib cheeb tsam uas lub zog zoo yog tsis zoo tab sis tas li uptime tsis yog qhov tseem ceeb.
Online UPS
Cov tshuab Ups online yog cov feem ntau tshaj thiab muab kev tiv thaiv zoo tshaj plaws rau lub zog. Lawv muab cov hluav taws xob txuas ntxiv thiab hloov lub zog tuaj rau DC ua ntej txhim kho nws rov qab rau AC. Txoj kev no ua kom cov khoom siv tau ua kom zoo ib yam, lub zog huv, tsis hais qhov hloov pauv lossis kev hloov kho. Cov Systems online UPS yog qhov zoo tshaj rau cov ntaub ntawv cov ntaub ntawv, tsev kho mob, thiab lwm thaj chaw tseem ceeb uas muaj kev cuam tshuam fais fab uas muaj kev puas tsuaj lossis downtime.
Vim li cas nws tseem ceeb kom xaiv txoj cai nce rau kev tiv thaiv surge?
Thaum xaiv lub system UPS los tiv thaiv kev tiv thaiv cov hwj chim, nws yog qhov tseem ceeb uas yuav tau txiav txim siab ntau yam:
Lub peev xwm
Lub UPS yuav tsum muaj lub peev xwm txaus los lis lub peev xwm sib txuas. Overloading cov UPS tuaj yeem ua rau nws tsis tiv thaiv cov khoom siv kom zoo thaum lub sij hawm. Nco ntsoov tias cov UPS yog qhov ntsuas rau tsawg kawg 20-30% muaj peev xwm ntau dua li tag nrho cov khoom siv hluav taws xob ntawm koj cov khoom siv.
Lub Sijhawm Teb Teb
Lub sijhawm teb sai yog qhov tseem ceeb rau kev tiv thaiv kev puas tsuaj thaum lub zog nthwv cua. Saib rau cov txheej txheem nce nrog lub sijhawm teb tsawg dua 5 milliseconds rau kev tiv thaiv zoo.
Surge Kev Tiv Thaiv
Txheeb xyuas cov UPS qhov kev tiv thaiv kev tiv thaiv kev ntxhov siab, feem ntau qhia hauv Joules. Lub siab dua cov kev ntaus nqi Joules, lub zog ntau dua cov nce tuaj yeem nqus tau ua ntej nws ua tsis tau zoo. Qhov kev ntsuas ntau dua ua kom muaj kev tiv thaiv zoo dua rau kev tiv thaiv loj.
Lub zog zoo
Xaiv cov txheej txheem nce siab uas muaj cov peev xwm zoo rau cov yam ntxwv zoo, xws li AVR thiab lim, ntxiv rau kev tiv thaiv surge. Qhov no yuav pab pov hwm koj cov cuab yeej los ntawm ob qho teeb meem thiab lwm cov teeb meem muaj teeb meem, xws li sags, spikes, thiab suab nrov.
UPS cov tshuab yog tsis tseem ceeb hauv kev tiv thaiv cov khoom tseem ceeb los ntawm cov hluav taws xob surges. Los ntawm kev muab lub zog ua haujlwm, kev nqus dej num, thiab lub sijhawm sai, UPS cov tshuab kom paub meej tias cov cuab yeej siv rhiab nyob nyab xeeb thaum muaj kev ntxhov siab. Thaum xaiv cov txheej txheem nce, nws yog qhov tseem ceeb uas yuav xav txog yam muaj peev xwm xws li muaj peev xwm, teb lub sijhawm, kev tiv thaiv screat, thiab ua kom muaj zog ua si. Nrog rau txoj cai UPS, kev lag luam thiab cov tib neeg tuaj yeem tiv thaiv lawv cov khoom siv los ntawm cov kev ua kom muaj kev puas tsuaj ntawm lub zog thiab ua haujlwm tsis tu ncua yam tsis muaj kev cuam tshuam.
