Nyob rau hauv lub hnub nyoog ntawm cov thev naus laus zis thev naus laus zis, ntse meters tau tawm los ua kev tswj hwm lub zog rau kev tswj hwm lub zog. Cov khoom siv no tsis yog tsuas yog siv hluav taws xob kev siv hluav taws xob tab sis kuj tau muab cov ntaub ntawv tiag tiag rau ob cov neeg siv khoom thiab cov khoom siv hluav taws xob. Nkag siab rau cov tib yam ntawm cov ntsuas ntse ntse yog qhov tseem ceeb rau kev nkag siab seb lawv muaj nuj nqi li cas thiab cov txiaj ntsig lawv tau txais. Ib qho kev ntsuas ntse ntse feem ntau muaj li ntawm peb ntu: hloov, ntsuas, thiab kev sib dhos. Hauv cov pawg no, ob peb tus tseem ceeb ua si lub luag haujlwm tseem ceeb, suav nrog cov sib nqus latching relay, tam sim no hloov, thiab manganin shunt.
1. Tus hloov pauv: Sib Nqus Latching Relay
Ntawm lub plawv ntawm lub ntsej muag ntse lub luag haujlwm yog qhov hloov, uas feem ntau yog pab txhawb nqa los ntawm aSib Nqus Latching Relay(MLR). Qhov kev tivthaiv no yog qhov tseem ceeb rau kev tswj hwm kev ntws ntawm hluav taws xob mus thiab los ntawm lub ntsuas. Tsis zoo li kev sib cais ib txwm muaj, uas yuav tsum muaj zog txuas ntxiv kom tswj tau lawv lub xeev, Latching Latching Relays rov qab los tuav lawv txoj haujlwm. Cov yeeb yaj kiab no tso cai rau lawv haus lub zog tsawg dua, ua rau lawv xaiv qhov zoo tshaj plaws rau ntse meters.
Lub MLR tuaj yeem hloov ntawm thiab tawm lub xeev yam tsis tas yuav muaj lub zog siv hluav taws xob tas li rau kev ua tau zoo. Lub peev xwm no tsis yog txo qis tag nrho hluav taws xob tau noj ntawm lub xov tooj ntse ntse tab sis kuj pab tau nws txoj kev ntseeg tau. Nyob rau hauv qhov kev tshwm sim ntawm lub zog hluav taws xob, MLR tuaj yeem tswj hwm nws lub xeev, kom lub xeev, kom cov meter txuas ntxiv ua haujlwm kom raug ib zaug fais fab tau rov qab los.
2. Qhov kev ntsuas: hloov pauv tam sim no thiab manganin shunt
Qhov ntsuas tivthaiv ntawm lub ntsuas ntsuas ntse yog qhov tseem ceeb rau kev siv gauging yog qhov tseeb. Ob lub tseem ceeb ntawm cov txheej txheem no yog qhov hloov pauv tam sim no (CT) thiab Manganin Shunt.
Tus hloov pauv tam sim no yog qhov tseem ceeb ntawm kev tso cai rau lub ntsuas ntsuas ntse los ntsuas qhov tam sim no ntws los ntawm hluav taws xob hluav taws xob. Nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm indectromagnetic induction, qhov chaw ua haujlwm tseem ceeb tshaj plaws uas yog cov khoom sib nqus uas ua rau muaj kev sib nqus tam sim no hauv kev hloov pauv theem nrab ntawm lub transformer. Qhov kev hloov pauv no tso cai rau kev nyab xeeb thiab raug ntsuas ntawm cov dej siab uas tsis tas yuav muaj kev sib txuas hluav taws xob.
CTS yog qhov tshwj xeeb hauv Smart Meters vim tias lawv tuaj yeem muab cov ntaub ntawv tiag tiag ntawm kev siv hluav taws xob, ua kom cov neeg siv txoj kev siv. Cov ntaub ntawv no tuaj yeem tsis tau rau ob tus neeg tau txais kev pab thiab cov khoom siv hluav taws xob, vim nws tso cai rau kev tswj lub zog zoo dua qub thiab kev kwv yees.
MANAGIN SHUNT
Lwm qhov kev ntsuas qhov tseem ceeb yog qhovMANAGIN SHUNTCov. Cov cuab yeej no yog siv los ntsuas qhov voltage poob thoob plaws ib tug paub kuj, cia cov meter 'ntse los laij cov ntws tam sim no los ntawm Circuit Court. MANAGIN, ib qho alloy ntawm tooj liab, manganese, thiab npib tsib xee, yog xaiv rau nws qhov kev kub kub tsawg, uas ua kom muaj kev ntsuas siab tau zoo.
Lub manganin shunt yog qhov tshwj xeeb tshaj yog nyob rau hauv ntse meters vim tias nws tuaj yeem ua kom muaj zog thaum tswj kev ruaj khov thiab precision. Qhov tseeb no yog qhov tseem ceeb rau muab cov ntaub ntawv siv nrog cov ntaub ntawv txhim khu
3. Cov sib dhos: kev sib xyaw ua ke ntawm cov khoom siv
Lub rooj sib txoos ntawm lub tshuab nthuav dav yog kev sib koom ua ke, ntsuas hluav taws xob, thiab cov hluav taws xob ntxiv uas ua rau kev sib txuas lus thiab kev ua haujlwm. Lub rooj sib txoos no tau tsim los xyuas kom meej tias txhua feem ua haujlwm ua haujlwm sib xyaw ua ke los muab cov ntaub ntawv raug thiab raws sijhawm.
Kev sib xyaw ua ke ntawm cov khoom sib xyaw no tso cai rau cov tuam txhab hluav taws xob nrog cov khoom siv hluav taws xob. Qhov kev sib txuas lus no yog qhov kev nce qib tseem ceeb tshaj li cov meters, uas xav tau kev nyeem ntawv. Nrog ntse meters, cov ntaub ntawv tuaj yeem kis tau nyob rau hauv lub sijhawm tiag tiag, ua rau kev siv hluav taws xob los saib xyuas hluav taws xob kev siv hluav taws xob.
Ntxiv mus, cov rooj sib txoos ntawm cov ntse meters feem ntau suav cov ntsiab lus siab xws li nrhiav tau TAMPER nrhiav tau, uas cov nqi hluav taws xob tsis txaus ntseeg rau kev dag ntxias lossis siv tsis tau kev dag ntxias. Qhov no ntxiv txheej ntawm kev ruaj ntseg yog qhov tseem ceeb rau kev tswj hwm kev ncaj ncees ntawm lub zog faib tawm.
Tag
Hauv cov ntsiab lus, cov ntsuas xov tooj ntse muaj ntawm peb qhov tseem ceeb: hloov, ntsuas, thiab kev sib dhos. Cov sib nqus latching relay ua haujlwm raws li tus hloov, muab kev tswj hwm tau zoo dua cov hluav taws xob ntws. Cov kev ntsuas cheebtsam, suav nrog tus hloov pauv tam sim no thiab mananin shunt, kom paub tseeb tias kev soj ntsuam muaj zog. Thaum kawg, cov kev sib sau ua ke nrog cov khoom siv no, ua kom cov kev sib txuas lus thiab cov ntaub ntawv ua haujlwm uas txhim kho kev tswj hwm kev siv hluav taws xob.
Raws li lub ntiaj teb txav ntawm ntau lub zog muaj zog siv zog, ntse metres yuav ua txoj haujlwm tseem ceeb tshaj plaws hauv kev pab cov tuam txhab thiab cov khoom siv hluav taws xob ua kom zoo. To taub cov khoom siv uas tsim cov khoom siv no yog qhov tseem ceeb rau kev txaus siab lawv qhov kev cuam tshuam rau kev ua haujlwm ruaj khov thiab kev tswj hwm. Nrog kev nce qib hauv thev naus laus zis, lub neej yav tom ntej ntawm cov ntse meters zoo li kev cog lus, paving txoj hauv kev rau smarter zog daws.
