Yuav ua li cas xaiv lub 3 theem fais fab meter?
Lub luag haujlwm tseem ceeb ntawm lub ntsuas hluav taws xob 3 theem yog ntsuas lub zog ua haujlwm thiab rov ua haujlwm hauv 3 theem circuit. Nws tuaj yeem ntsuas kev siv hluav taws xob sib txawv ntawm lub sijhawm sib txawv, khaws tag nrho lub zog siv thiab kev siv lub zog ntawm cov nqi sib txawv, thiab ua haujlwm xws li lub sijhawm khov, khov tam sim, pom zoo khov, thiab khov txhua hnub ntawm kev siv zog. Tsis tas li ntawd, lub ntsuas hluav taws xob 3 theem kuj tseem muaj cov nqi siv thiab lub sijhawm siv, tso cai rau kev hloov pauv ntawm daim ntawv qhia hnub, moos, thiab lub sijhawm tariff.
Nyob rau hauv cov nqe lus ntawm kev nthuav dav zog, tam sim no 3 theem fais fab meters tsis tsuas yog ntsuas hluav taws xob lub zog, tab sis kuj muaj ntau yam teeb liab tso zis interfaces, kev sib txuas lus interfaces, thiab lwm yam. ' meter ', uas pab cov neeg siv kom nkag siab qhov kev siv tag nrho ntawm lub ntsuas hluav taws xob thiab xyuas kom nws ua haujlwm li qub.
Thaum xaiv qhov tsim nyog 3 theem fais fab ntsuas, cov hauv qab no yuav tsum tau xav txog:
1. Qhov tseeb: Qhov tseeb yog ib qho tseem ceeb ntawm cov ntsuas hluav taws xob. Qhov siab dua qhov tseeb, qhov tseeb dua qhov ntsuas hluav taws xob lub zog yuav yog. Rau 3 theem fais fab ntsuas, feem ntau pom zoo kom xaiv Chav 0.5 lossis 1.
2. Ntau yam: Cov qauv sib txawv ntawm 3 theem fais fab ntsuas muaj ntau yam kev xaiv. Xaiv qhov ntau yam uas tsim nyog tuaj yeem ua kom qhov tseeb thiab txhim khu kev ntsuas lub zog. Rau 3 theem fais fab ntsuas ntsuas qhov kawg ntawm lub voj voog, feem ntau siv 100A tam sim no. Rau 3 theem hluav taws xob ntsuas hluav taws xob ncaj qha ntsia ntawm qhov kawg ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob, CT-hom fais fab ntsuas feem ntau yog siv, nrog cov ntsuas hluav taws xob ua piv txwv los ntawm cov khoom siv hluav taws xob sab nraud thiab cov hluav taws xob hloov hluav taws xob.
3. Nta: Kev xaiv ntawm kev ua haujlwm rau 3 theem fais fab ntsuas kuj tseem ceeb heev. Los ntawm kev xaiv cov haujlwm tsim nyog thiab kev nthuav dav xws li cov khoom siv tawm, cov kev xav tau tiag tiag tuaj yeem ua tiav.
4.Kev sib txuas lus muaj nuj nqi, tariff muaj nuj nqi, load tswj muaj nuj nqi, bidirectional metering muaj nuj nqi, thiab lwm yam. yog tag nrho cov kev siv zog tsim los ntawm 3 theem fais fab meters kom tau raws li kev lag luam xav tau.
Hom thiab zoo: Cov npe nrov npe ntawm 3 theem fais fab ntsuas muaj qhov zoo dua thiab kev pab cuam tom qab muag, uas tuaj yeem txo qhov teeb meem ntawm kev siv thiab tu. Kev tsim, kev tsim kho, thiab kev tsim khoom ntawm 3 theem hluav taws xob ntsuas hluav taws xob muaj cov ntsiab lus siab, yog li cov chaw tsim khoom ntawm lub ntsuas hluav taws xob yuav tsum muaj peev xwm ua haujlwm siab thiab lub suab ua haujlwm.
5.Tus nqi hluav taws xob siv: Raws li qhov sib txawv siab thiab tsis tshua muaj hluav taws xob siv hluav taws xob, 3 theem hluav taws xob ntsuas hluav taws xob tuaj yeem muab faib ua ob pawg: 3 theem peb-hlau meters thiab 3 theem plaub-hlau meters, nrog rau qhov sib txawv ntawm cov meters muaj qhov sib txawv voltage thiab tam sim no.
6.Qhov xav tau tiag tiag: Ua ntej kev yuav khoom, cov neeg siv tuaj yeem txiav txim siab seb lawv qhov kev xav tau tiag tiag yog dab tsi thiab xaiv 3 theem fais fab ntsuas tus qauv uas yog tsom rau cov kev xav tau. Piv txwv li, qee cov neeg siv khoom lag luam yuav xav tau ntau cov ntaub ntawv txheeb xyuas thiab yog li yuav tsum xaiv lub ntsuas hluav taws xob muaj tseeb dua.
Xaiv qhov tsim nyog 3 theem fais fab ntsuas yuav tsum muaj kev txiav txim siab ntawm yam xws li qhov tseeb, ntau yam, kev ua haujlwm, hom thiab zoo, kev siv hluav taws xob, thiab kev xav tau tiag tiag. Thaum lub sij hawm yuav thiab siv cov txheej txheem, kuj yuav tsum tau them nyiaj mloog mus rau cov khoom piav qhia, specifications, thiab cov ntsiab lus tseem ceeb nyob rau hauv thiaj li yuav siv tag nrho cov kev ua tau zoo thiab functionality ntawm 3 theem fais fab meter.
