Raws li cov khoom siv tseem ceeb rau kev ntsuas hluav taws xob hauv cov khoom siv fais fab, lub chaw tsim hluav taws xob ncaj qha rau nws cov kev ntsuas hluav taws xob ncaj qha, muaj kev ntseeg siab, thiab kev txawj ntse. Niaj hnub nimno me me meters feem ntau muaj ntau cov kev ua haujlwm ntau yam ua haujlwm ua haujlwm ua haujlwm ua ke los sau, txheej txheem, thiab xa cov ntaub ntawv siv zog. Kab lus no yuav qhia meej cov qauv qauv theem pib thiab cov khoom tseem ceeb ntawm lub tshuab hluav taws xob ntawm ob lub tshuab siv hluav taws xob thiab hluav taws xob kev xav.
Cov qauv ntawm cov tshuab ntsuas hluav taws xob
Kev siv hluav taws xob ib txwm muaj meters (xws li induction meters) feem ntau cia siab rau lub hauv paus ntsiab lus ntawm hluav taws xob. Lawv cov qauv qauv tseem ceeb suav nrog cov hauv qab no:
1.Drive lub caij
Lub tsav tsheb muaj lub voltage coil thiab ib tug tam sim no coil. Lub voltage coil txuas nrog rau hauv parallel nrog lub nra, thaum lub kauj tam sim no txuas nrog hauv cov kab nrog lub nra. Thaum energized, no ob coils tsim ib qho kev sib nqus sib nqus, uas ua rau ntawm txhuas turttable, ua rau nws tig.
2.Trotating caij
Lub caij sib hloov feem ntau muaj cov txhuas turntable thiab tus ncej. Lub sib nqus daim teb tsim los ntawm cov tsav lub zog tig tig cov txhuas turttable ntawm lub zog nrawm rau lub zog siv los ntawm lub nra.
3.braking lub caij
Cov hlau nplaum nres tsim cov braking torque nyob rau hauv kev coj rov qab ntawm lub turntable hloov pauv, ua kom nrawm nrawm thiab yog li ntsuas ruaj khov kho.
4. Txee
Lub txee txuas nrog rau txoj kab sib hloov ntawm lub tsheb ciav hlau iav. Nws sau cov naj npawb ntawm cov kev hloov pauv ntawm hu thiab hloov qhov no mus rau hauv kilowatt {}}}}})).
Cov neeg kho tshuab meters yog yooj yim thiab pheej yig, tab sis lawv raug kev txom nyem los ntawm cov kev txwv xws li qhov tseeb uas tau sib txuas lus remotely. Lawv tau maj mam hloov los ntawm cov metronic meters.
Tus qauv ntawm hluav taws xob meters
Electronic Meters siv cov khoom siv tshuab digital thiab microprocessorecess technology, muab cov ntsuas kev ntsuas siab yog thiab nthuav dav ua haujlwm. Lawv lub qauv tseem ceeb suav nrog:
1. Volfage thiab cov qauv tam sim no
Electronic meters khaws voltage thiab tam sim no cov paib uas siv cov tshuab hluav taws xob lossis hloov pauv mus rau hauv qis {- tam sim no tsim nyog rau kev ua.
2. Analog - rau - hack digital (ADC)
Cov cim ntsuas pom tau hloov dua tshiab los ntawm ADC rau hauv cov cim digital rau lub microprocessor rau txuas ntxiv kev siv hluav taws xob.
3. Microprocessor (MCU)
Lub microprocessor yog "lub hlwb" ntawm hluav taws xob hauv hluav taws xob, lub luag haujlwm rau cov ntaub ntawv ua, kev ntsuas hluav taws xob, cia, thiab tswj kev tswj hwm. Nws tuaj yeem ua cov lej ntau ntxiv raws li qhov xav tau, xws li muaj zog thiab voltage Riamkas Rhais Pleev.
4.DISPlay module
Cov hluav taws xob hluav taws xob metres feem ntau yog siv cov kua siv lead ua kua (LCD) lossis LED zaub kom pom cov ntaub ntawv xws li kev noj hluav taws xob, hluav taws xob, thiab tam sim no. Qee qhov siab -}}}}}}} {- kab kab.
5.Umunication module
Niaj hnub nimno ntse meters sib txuas lus sib txuas lus xws li Rs -, txhawb nqa cov chaw taws teeb nyeem, thauj khoom, tswj hwm.
6.Memory chav tsev
Electronic meters tau ua - hauv tsis {}} lub cim xeeb, thiab cov ntaub ntawv hloov kho, kom cov ntaub ntawv tsis muaj txiaj ntsig thaum lub sijhawm hluav taws xob.
7.Power Mov Ntawv Module
Kev siv hluav taws xob metronic me me Feem ntau siv cov hluav taws xob pab hluav taws xob (xws li lub transformer lossis hloov fais fab). Qee cov qauv tuaj yeem kos lub zog ncaj qha los ntawm txoj kab ntsuas kom ntseeg tau tias kev ua haujlwm yooj yim thaum lub sijhawm ua haujlwm hluav taws xob.
Cov qauv tshwj xeeb ntawm cov hluav taws xob tshwj xeeb meters
1.prepaid meters
Raws li cov tshuab hluav taws xob me me, cov meters sib xyaw I IC daim npav lossis xov tooj cua ntsuas (RF) kev siv hluav taws xob ua ntej siv thiab siv encryption los tiv thaiv kev nyiag khoom hluav taws xob.
2.Multi - Txoj haujlwm meters
Ntxiv rau kev siv hluav taws xob yooj yim, cov meters no tseem muaj kev txheeb xyuas lub siab, thiab cov txhaum txiav, ua rau cov neeg siv khoom lag luam.
3.Qhov meters
Smart Meters yog ib qho kev hloov kho tshiab ntawm cov hluav taws xob meters, ua ke {{} {}}}}}}}}} Kev sib txuas lus tus nqi teb, thiab kev tswj hwm tsheb sib tshooj.
Lub ntsiab
Cov txheej txheem kev tsim hluav taws xob metres tau hloov zuj zus nrog cov txheej txheem thev naus laus zis, los ntawm cov tshuab rau hauv tshuab rau cov ntse meters. Lawv cov ntsiab cai tseem ceeb ib txwm muaj kev ntsuas kev siv tau, kev ua haujlwm txhim khu kev qha, thiab kev tswj hwm kev txawj ntse. Yav tom ntej, nrog kev txhim kho ntawm lub zog internet, hluav taws xob meters yuav txuas ntxiv ua ke txawj ntse thiab cov ntaub ntawv tseem ceeb, ua cov kab ke tseem ceeb hauv cov kab ke ntse. Nkag siab txog cov qauv hluav taws xob meters tsis tsuas yog pab txhawb kev txij nkawm thiab daws teeb meem tab sis kuj lays lub hauv paus rau kev tsim kho cov tshuab hluav taws xob tshiab.
