Piav kom pom cov kev sib nrig sib nruab nrab ntawm UPS thiab cov generator teeb
Nrog txoj kev loj hlob sai hauv Is Taws Nem, qhov kev thov rau lub zog ua haujlwm UPS thiab cov generators nyob rau hauv cov chaw khaws ntaub ntawv yog nce zuj zus, thiab qee qhov teeb meem tshiab tau tshwm sim. Nyob rau hauv daim ntawv no, qhov feem ntau ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv lub tshuab hluav taws xob tau muab cais tawm thiab cov lus tseeb piav qhia kom meej qhov teeb meem ntawm qhov teeb meem, thiab nrhiav kev daws teeb meem.
1 txuam teeb meem ntawm generator teeb thiab UPS
Manufacturers thiab cov neeg siv ntawm UPS fais fab mov tshuab tau ntev pom qhov teeb meem piv txuam ntawm cov generator set thiab UPS, tshwj xeeb tshaj yog cov kev sib haum xeeb uas tau tsim los ntawm rectifier tsis zoo rau cov khoom siv hluav taws xob xws li qhov kev tiv thaiv hluav taws xob ntawm cov generator teeb thiab cov synchronous Circuit Court ntawm UPS. Qhov tshwm sim yog cuab kev heev. Vim li no, cov kws kho tsheb tsim cov lim tawm tswv yim thiab siv nws mus rau UPS kom ua zoo tswj cov kev sib raug zoo tam sim no hauv UPS daim ntawv thov. Cov ntxaij lim dej no ua si lub luag haujlwm tseem ceeb hauv qhov kev sib tw nrog lub teeb tsa nrog cov generator.
Zoo tag nrho cov lim tswv yim siv cov capacitors thiab inductors los nqus dej harmonics tam sim no ntawm cov tswv yim UPS. Tus tsim ntawm cov khoom siv hluav taws xob yuav siv sij hawm mus rau hauv tus txheej txheem qhov feem pua ntawm qhov tau siab tshaj plaws ntawm kev sib haum xeeb mus rau UPS Circuit Court thiab ntawm tag nrho cov khoom thauj. Lwm cov txiaj ntsig ntawm cov ntxaij lim dej feem ntau yog ua kom lub zog qhov tseem ceeb ntawm cov nqi thauj hauv UPS. Txawm li cas los xij, lwm qhov kev tsim nyog ntawm daim ntawv thov lub lim dej lim yog tias tag nrho kev ua haujlwm ntawm UPS raug txo. Cov ntxaij lim dej feem ntau siv li 1% ntawm lub zog hauv UPS. Tus qauv tsim ntawm cov khoom lag luam lim dej yeej ib txwm nrhiav ib qho kev sib npaug ntawm cov txiaj ntsim zoo thiab tsis zoo.
Yuav kom ua tiav cov kev ua haujlwm ntawm UPS, cov tub ua haujlwm UPS nyuam qhuav tau tsim kho kom zoo dua rau cov kev siv hluav taws xob. Qhov nce ntawm kev ua haujlwm tau zoo yog nyob ntawm cov ntaub ntawv IGBT (Insulated Gate-Level Transistor) mus rau UPS. Lub high efficiency ntawm IGBT inverter tau coj mus rau kev txhim kho ntawm UPS. Lub lim tshuaj muaj peev xwm nqus tau cov kev sib raug zoo tam sim no thaum uas ua rau me me feem ntawm lub hwj chim. Hauv cov ntsiab lus, qhov sib piv ntawm cov kev ntxawg hauv kev lag luam hauv qhov txo tsawg zog, thiab UPS txo qis thiab kev ua haujlwm. Qhov teeb meem ntawm compatibility ntawm UPS thiab generators tau arisen dua.
2 qhov teeb meem muaj zog
Feem ntau, cov tib neeg them nyiaj rau lub xeev ua hauj lwm ntawm UPS ntawm tag nrho cov load lossis ze ntawm tag nrho cov load. Feem ntau cov engineers to taub UPS kev ua haujlwm cov kev coj ntawm kev thauj khoom, tshwj xeeb tshaj yog cov yam ntxwv ntawm cov khoom siv lim, tab sis muaj tsawg tus neeg txaus siab nyob rau hauv lub lim ntawm lub lim tsis muaj load los yog nyob ze tsis muaj load. Tom qab tag nrho, qhov UPS thiab nws cov hluav taws xob system muaj kev txuam me ntsis rau cov kev sib raug zoo tam sim no nyob rau hauv lub teeb ntsiag to ntawm cov neeg mob. Txawm li cas los xij, qhov kev khiav hauj lwm tsis nyob ntawm UPS tsis muaj qhov khoom, tshwj xeeb tshaj yog cov hluav taws xob muaj peev xwm, yog qhov tseem ceeb rau kev sib tw ntawm UPS nrog lub tshuab hluav taws xob.
Lub lim dej tshiab tsim tau lim tau zoo los txo cov kev sib raug zoo tam sim no thiab ua kom muaj zog txaus ntawm qhov puv load. Txawm li cas los xij, hauv qab tsis muaj qhov nyhav los yog tsis tshua muaj me me, qhov tseem ceeb ntawm qhov muaj peev xwm ua kom muaj cov hmoov lead loj txaus, tshwj xeeb yog cov uas ua tau raws li qhov 5% siab tshaj tam sim no. Feem ntau, cov lim dej ntawm ntau lub nruab UPS tuaj yeem ua rau lub hwj huam tseem ceeb txo thaum qhov nyhav tshaj 25%. Dua li qhov no, qhov tseem ceeb tawm tswv yim tsis tshua muaj tsawg dua li 30%, thiab qee lub tshuab tshiab kuj tau mus txog qhov muaj zog tsis muaj zog ntawm tsawg tshaj li 2%, nyob ze rau qhov kev them nqi siab loj.
Qhov teeb meem no tsis cuam tshuam qhov tsim tawm UPS thiab cov khoom tseem ceeb, thiab cov mains transformers thiab kis kab mob sib kis thiab tsis muaj kev cuam tshuam. Tab sis cov generators yog txawv. Cov kws paub txog kev tsim hluav taws xob (generator engineers) paub hais tias lub tshuab hluav taws xob yuav tsis ua hauj lwm zoo thaum nws muaj lub zog loj loj. Thaum nws txuas nrog rau qhov txo qis zog, feem ntau tsawg dua li 15% mus rau 20% capacitive, Lub tshuab hluav taws xob tej zaum yuav raug kaw vim muaj kev tsis txaus siab. Qhov tshwm sim ntawm kev kaw dej tom qab qhov hluav taws xob tsis ua hauj lwm, qhov hluav taws xob thaum muaj xwm ceev khiav tsav UPS system load yuav ua rau muaj kev sib tsoo. Downtime ua rau muaj kev phom sij rau kev mob hnyav vim yog ob qho laj thawj: (1) lub tshuab hluav taws xob yuav tsum tau rov pib dua tshiab thiab yuav tsum yog ua ntej xaus UPS cov roj teeb tawm; (2) lub tshuab hluav taws xob tej zaum yuav ua rau "overvoltage" ntawm lub cev ua ntej qhov kev kaw, nws cov khoom siv sib txuas lus, hluav taws kub tswb, kev tes hauj lwm, thiab tej zaum UPS modules yuav raug puas tsuaj.
Yuav ua kom mob loj tuaj, tom qab muaj kev sib tsoo, nws yog qhov nyuaj rau qhov txawv ntawm cov dej num, cim qhov teeb meem thiab kho nws. Qhov chaw ua lag luam hais tias UPS qhov system yog nyob rau hauv zoo mob thiab taw qhia tias cov teeb meem zoo li no tau tshwm sim nyob rau hauv tib lub cuab yeej siv lwm qhov chaw. Cov chaw tsim hluav taws xob tsim tau hais tias nws yog qhov teeb meem thauj khoom thiab yuav tsis kho cov generator los daws qhov teeb meem. Tib lub sij hawm, tus neeg siv khoom siv tshuab piav txog cov lus qhia thiab xav kom sib haum. Yuav kom nkag siab tias vim li cas ho muaj xwm txheej thiab yuav ua li cas kom tsis txhob muaj nws (los yog yuav ua li cas nrhiav kev daws rau hauv ib daim ntawv tseem ceeb), koj yuav tsum xub to taub txoj haujlwm kev sib raug zoo ntawm lub tshuab hluav taws xob.
