Niaj hnub no, nrog kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, lub ntsuas hluav taws xob tshiab tau nce mus rau ntau lab tsev neeg. Hauv qab no yog lub ntsuas hluav taws xob zoo li qub watt-teev nrog cov ntsiab lus high-tech thiab prepaid watt-teev meter nrog daim npav hluav taws xob.
Static watt-teev meter
Static watt-teev meter yog ib hom tshiab ntawm watt-teev meter nrog cov txheej txheem siab tshaj plaws ntawm kev ntsuas hluav taws xob hluav taws xob, tau txais txiaj ntsig zoo ntawm ib txwm siv hluav taws xob induction watt-teev meter, txais yuav cov qauv tiv thaiv tag nrho thiab kaw tag nrho, uas muaj kev cuam tshuam zoo electromagnetic cuam tshuam. kev ua tau zoo thiab integrates lub zog txuag, kev ntseeg siab, lub teeb yuag, siab raug, siab tshaj thiab tiv thaiv tub sab.
Lub static watt-teev meter tau txais tam sim no sampling teeb liab los ntawm shunt, voltage sampling teeb liab los ntawm divider, khoom teeb liab ntawm voltage thiab tam sim no los ntawm multiplier, thiab ces generates ib tug suav mem tes uas nws zaus yog proportional rau cov khoom ntawm voltage thiab tam sim no los ntawm zaus conversion. Stepping lub cev muaj zog yog tsav los ntawm kev faib zaus los ua qhov ntsuas ntsuas.
Static watt-teev meters tuaj yeem muab faib ua ib-theem hluav taws xob hom, peb-theem hluav taws xob hom thiab peb-theem plaub-xaim hluav taws xob hom raws li qhov voltage. Lawv tuaj yeem muab faib ua ib hom thiab ntau hom haujlwm (active, reactive thiab compound type) raws li lawv siv.
Static watt-teev meter installation thiab siv cov kev cai, thiab cov neeg kho tshuab watt-teev meter yog roughly tib yam, tab sis cov xaim yuav tsum tuab, kom tsis txhob muaj cua sov vim kev sib cuag tsis zoo.

Electronic watt-teev meter daim ntawv qhia
Kev them nyiaj watt-teev meter, tseem hu ua IC card meter lossis magnetic card meter, raws li qhia hauv daim duab. Nws tsis tsuas yog muaj ntau yam zoo ntawm hluav taws xob watt-teev meter, tab sis kuj siv cov cuab yeej microelectronic siab heev los sau, txheej txheem thiab txuag cov ntaub ntawv, kom paub txog kev tswj hwm kev them nyiaj ua ntej thiab tom qab ntawd siv hluav taws xob.
Daim npav hluav taws xob them ua ntej watt-teev ntsuas ntsuas ntsuas qhov ntsuas hluav taws xob thiab cov cim tam sim no los ntawm kev tiv thaiv hluav taws xob sib faib network thiab shunting cov ntsiab lus raws li thiab xa lawv mus rau lub zog hluav taws xob metering nti. Nyob rau hauv lub nti, qhov sib txawv amplification, AD hloov dua siab tshiab thiab multiplier circuit tau siv rau kev ua haujlwm sib npaug. Kev ntsuas hluav taws xob tam sim ntawm kev ntsuas hluav taws xob hluav taws xob tau ua tiav, thiab tom qab ntawd qhov nruab nrab lub zog ntawm kev ntsuas hluav taws xob hluav taws xob tau tso tawm thiab ntsuas los ntawm kev lim dej thiab digital thiab zaus hloov pauv. Zaus pulse teeb liab nrog proportional npaum li cas, nyob rau hauv uas siab zaus mem tes tso zis yuav siv tau rau calibration, tsawg zaus mem tes tso zis rau lub meter zaub fais fab thiab CPU rau cov ntaub ntawv ua.
Daim npav hluav taws xob them ua ntej watt-teev meter tuaj yeem muab faib ua ib theem thiab peb theem. [5]
Cov yam ntxwv ua haujlwm ntawm Intelligent Meter
Cov ntsuas ntse yog tsim los nrog cov khoom siv hluav taws xob sib xyaw ua ke, yog li piv nrog cov ntsuas induction, cov ntsuas ntsuas ntse muaj qhov zoo ntawm kev ua haujlwm thiab kev ua haujlwm.
1) Kev siv hluav taws xob. Vim tias cov ntsuas ntsuas ntse yog tsim los ntawm cov khoom siv hluav taws xob, kev siv hluav taws xob ntawm txhua lub 'meter' tsuas yog hais txog 0.6-0.7W. Rau ntau tus neeg siv centralized ntse ntsuas, qhov nruab nrab lub zog rau txhua tsev neeg tsawg dua. Feem ntau, lub zog noj ntawm txhua qhov induction meter yog li 1.7W.
2) Qhov tseeb. Raws li qhov kev ua yuam kev ntawm qhov ntsuas ntsuas, qhov ntsuas qhov yuam kev ntawm 2.0 qib hluav taws xob watt-teev ntsuas ntsuas yog (ntxiv rau 2 feem pua) hauv thaj tsam ntawm 5 feem pua -400 feem pua calibration tam sim no , thiab qib raug yog 1.0 qib, uas yog siv dav rau tam sim no, thiab qhov yuam kev me dua. Qhov yuam kev ntau ntawm induction watt-teev meter yog 0 86 feem pua ~ 5.7 feem pua . Tsis tas li ntawd, vim yog qhov tsis xws luag ntawm cov khoom siv kho tshuab, qhov induction watt-teev meter mus qeeb thiab qeeb, thiab qhov yuam kev kawg yuav loj dua thiab loj dua. Lub Xeev Grid tau ua qhov chaw kuaj xyuas ntawm induction meters, thiab pom tias tom qab ntau tshaj 50 feem pua ntawm induction meters tau siv rau tsib xyoos, lawv cov kev ua yuam kev ntau tshaj qhov tso cai.
3) Tshaj dhau thiab lub zog ntau zaus. Qhov ntau dhau ntawm cov ntsuas ntse ntse feem ntau tuaj yeem ncav cuag 6-8 zaug thiab muaj ntau yam. Tam sim no, 8-10 zaus 'meter' tau dhau los ua qhov kev xaiv ntawm ntau thiab ntau tus neeg siv, qee qhov tuaj yeem ncav cuag 20 npaug ntawm ntau yam. Kev khiav hauj lwm zaus kuj yog dav, xws li ntawm 40 txog 1000Hz. Lub overload multiples ntawm induction meters feem ntau tsuas yog 4 zaug, thiab kev khiav hauj lwm zaus tsuas yog 45-55 Hz.
4) Muaj nuj nqi. Vim yog cov cuab yeej siv hluav taws xob, cov ntsuas ntse ntse tuaj yeem sib txuas nrog cov khoos phis tawj los ntawm cov txheej txheem kev sib txuas lus, thiab cov khoom siv tuaj yeem tswj tau thiab tswj hwm los ntawm programming software. Yog li ntawd, cov ntsuas ntse tsis tsuas yog muaj cov yam ntxwv ntawm qhov me me, tab sis kuj muaj cov haujlwm ntawm cov chaw taws teeb tswj, ntau tus nqi, kev txheeb xyuas cov khoom tsis zoo, tiv thaiv tub sab, hluav taws xob them ua ntej thiab lwm yam. Ntxiv mus, lawv tuaj yeem ua tau raws li qhov sib txawv ntawm kev tswj hwm kev ua haujlwm los ntawm kev hloov kho qhov sib txawv hauv kev tswj software, uas yog qhov nyuaj lossis tsis tuaj yeem ua tiav rau ib txwm siv induction meters.
