Yuav ua li cas xaiv lub ntsuas hluav taws xob los ntawm tam sim no?
Muaj ob qhov txiaj ntsig tam sim no ntawm lub vaj huam sib luag ntawm lub ntsuas ntsuas ntse, raws li pom hauv daim duab hauv qab no.Lub Linyangmeterqhab nia 5 (60) A. 5A yog qhov yooj yim tam sim no thiab 60A yog qhov ntsuas qhov siab tshaj plaws tam sim no.Yog tias qhov tam sim no tshaj 60A, nws yuav dhau mus thiab lub ntsuas ntsuas ntse yuav hlawv.Yog li ntawd, thaum xaiv lub ntsuas ntsuas ntse, ntawm ib sab, nws yuav tsum tsis txhob qis tshaj qhov tam sim no thiab ntawm qhov tod tes, nws yuav tsum tsis txhob siab tshaj qhov siab tshaj plaws tam sim no.
Piv txwv tias peb cov khoom siv hauv tsev: 300W computer, 350W TV, 1500W cua txias, 400W tub yees, 2000W dej rhaub.Peb tuaj yeem xam raws li hauv qab no: tam sim no = (300 + 350 + 1500 + 400 + 2000) W / 220V≈ 20.6A.Peb yuav tuaj yeem nruab 5 (60) A meters vim tias muaj peev xwm ntxiv cov khoom siv yav tom ntej.
Sim xaiv hom ntsuas raws li qhov ntsuas tam sim no.Cov ntsuas hluav taws xob tau muab faib ua peb theem hluav taws xob ntsuas thiab ib-theem hluav taws xob ntsuas.Feem ntau, peb-theem hluav taws xob ntsuas hluav taws xob yog siv thaum ntsuas tam sim no ntau dua 80A, tab sis muaj ntau hom thiab cov ntsiab lus ntawm ib-theem hluav taws xob meters thiab peb-theem hluav taws xob ntsuas, yog li yuav ua li cas xaiv cov hom thiab specifications?
Yuav ua li cas xaiv tus qauv ntawm ib theem 'meter'
Ib theem ntsuas ntsuas kuj muaj cov ntsuas hluav taws xob thiab ntsuas ntsuas ntse.Rau cov tsev xauj tsev thiab qhov chaw nyob uas tsis muaj kev ua haujlwm nyuaj ntxiv, peb tuaj yeem xaiv cov ntsuas hluav taws xob ib-theem.Hom ntsuas no muaj cov haujlwm dav dav ntawm kev ntsuas.Yog tias xav tau ntau lub zog xws li lub zog siab thiab lub kwj deg, lub sijhawm them nqi, kev them nyiaj ua ntej, peb yuav xaiv cov ntsuas ntse.Tam sim no, ntau lub zej zog ua kev kho dua tshiab nrog cov ntsuas ntse.
Yuav ua li cas xaiv tus qauv ntawm peb-theem hluav taws xob ntsuas
Qhov tseeb, yuav ua li cas xaiv lub ntsuas hluav taws xob peb theem kuj yuav tsum tau kuaj xyuas seb yuav tsum ua haujlwm li cas.Feem ntau, yog tias tsuas yog lub zog yuav tsum tau kuaj xyuas, cov kev cob qhia, cov chaw tsim khoom me lossis cov khw muag khoom lag luam, tsuas yog yuav tsum xaiv cov khoom siv hluav taws xob zoo tib yam peb theem hluav taws xob, xws li Linyang SM350, uas muaj ntau yam kev qhia tshwj xeeb rau xaiv, xws li 1.5. (6) A, 5 (40) A, 10 (60) A, thiab lwm yam, Qhov siab tshaj plaws tuaj yeem yog 100A.Yog tias qhov tam sim no ntawm ib theem siab tshaj 100A, nws raug nquahu kom siv 1.5 (6) A thiab transformer ua ke.Hom ntsuas no feem ntau tsis tshua muaj hluav taws xob ntsuas nrog qhov ntsuas hluav taws xob ntawm 220/380V.
Nyob rau hauv lub rhiav ntawm nruab nrab thiab loj factories, tam sim no kuj loj, thiab ib theem tam sim no yuav tsum tshaj 100A.Tsis tas li ntawd, cov chaw tsim khoom loj tsis yog tsuas yog yuav tsum tau kuaj xyuas cov hluav taws xob hluav taws xob, tab sis kuj yuav tsum tau ua ntau cov ntaub ntawv txheeb xyuas, xws li kev tsom xam ntawm lub zog load nkhaus, thiab lwm yam. Yog li ntawd, cov khoom siv hluav taws xob hluav taws xob zoo tib yam yog deb ntawm kev ua tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob. cov neeg siv khoom.Lub sij hawm no peb xaiv peb lub tshuab hluav taws xob peb-theem lossis ntau lub tshuab hluav taws xob.Cov ntsuas hluav taws xob zoo li no tuaj yeem ncav cuag qhov tseeb ntawm 0.5s thiab 0.2s, nrog rau kev ntsuas ntau dua thiab tus nqi txheeb ze.Hom hluav taws xob ntsuas hluav taws xob no muaj lub zog muaj zog ntau dua li cov ntsuas hluav taws xob saum toj no, xws li kev ntsuas lub sij hawm sib faib thiab kev them nqi, kev soj ntsuam kev ntsuas thiab cov ntaub ntawv teev xwm txheej, thiab lwm yam. Yog li ntawd, tus nqi yuav siab dua.
Nyob rau hauv cov ntaub ntawv ntawm ib tug fais fab nroj tsuag metering neeg siv, substation cov neeg siv, peb-theem peb-xaim high-voltage hluav taws xob meter tej zaum yuav xav tau.Kuj tseem muaj qee qhov kev lag luam ntawm high voltage, uas siv peb-theem peb-xaim high voltage meter thiab peb theem plaub hlau voltage meter nyob rau hauv lub high voltage txee, thiab txiav txim siab seb ib tug yuav siv raws li nyob rau hauv lub site yuav tsum tau.Feem ntau, qhov loj dua qhov tam sim no yuav tsum tau ntsuas yog, qhov siab dua qhov yuav tsum tau yog thiab yog li ntawd, qhov siab dua qhov ntsuas tus nqi.Tus nqi ntawm 0.2S 'meter' yuav ntau dua peb npaug ntawm 0.5S 'meter'.
Yuav ua li cas xaiv lub ntsuas ntsuas ntse
Lub ntsuas hluav taws xob zoo yuav tsum muaj ntau lub zog muaj zog, ntxiv rau cov haujlwm saum toj no, tab sis kuj tseem muaj cov haujlwm ntawm kev tiv thaiv kev tiv thaiv, cov ntaub ntawv khaws cia, cov ntaub ntawv teev tseg, kev ntsuas cov chaw taws teeb, kev saib xyuas kev siv hluav taws xob, thiab lwm yam haujlwm, suav nrog cov chaw taws teeb ntsuas. , kev siv hluav taws xob saib xyuas kev ua haujlwm.Peb siv nyiaj ntau dua li cov ntsuas hluav taws xob ib txwm siv los yuav cov ntsuas ntsuas tsis yog kom pom lub zog, tab sis pom lwm yam kev txawj ntse ntawm lub ntsuas ntsuas ntse.
Kev soj ntsuam nrog kev ua haujlwm ntawm cov cuab yeej saib xyuas, nws tuaj yeem pom los ntawm kev txheeb xyuas cov ntaub ntawv thaum hloov chaw, thaum kaw, nws qhov hluav taws xob, tam sim no, lub zog hluav taws xob sib txawv ntawm qhov qub, seb cov ntaub ntawv no thiab cov khoom siv ua haujlwm kub npaum li cas, txawm tias qhib theem. , seb vim hais tias ntawm mechanical teeb meem yog overburdened, thiab lwm yam, muaj ib tug saib cov ntaub ntawv yog ib tug mesh.
Tus nqi ntawm smart meters nrog tej thaj chaw deb prepaid meter nyeem ntawv system
Thaum lub ntsuas ntsuas ntse tau nruab nrog cov chaw taws teeb prepaid meter nyeem ntawv, nws tsis tsuas yog paub qhov chaw taws teeb tsis siv neeg nyeem ntawv, tab sis kuj tseem tuaj yeem rub tawm qhov hloov pauv, them nqi online, kho qhov txhaum thiab lwm yam haujlwm.Cov neeg ua haujlwm tswj xyuas hluav taws xob tseem tuaj yeem ua haujlwm 24-teev saib xyuas thiab tswj los ntawm lub computer lossis mobile APP, thiab cov neeg siv kuj tuaj yeem them tus nqi thiab nug txog cov nqi hluav taws xob.Nyob rau tib lub sijhawm, nws yog cov txheej txheem ntawm kev sau cov ntaub ntawv zoo tshaj plaws ntawm lub zog thiab kev tswj hwm kev daws teeb meem, suav nrog cov kev pabcuam vaj tsev, kev saib xyuas engineering, cov neeg siv APP, cov neeg siv nyiaj txiag, muab kev pabcuam huab cua tsis siv neeg, tswj cov nqi khiav lag luam, txhim kho cov txiaj ntsig, thiab pab cov lag luam. kom scale nce sai.
