Xaiv thiab txuas qhov hluav taws xob 'meter'

Electric 'meter' - hluav taws xob ntsuas ntsuas no yog npaj coj mus rau hauv tus account lub hluav taws xob noj ob AC thiab DC. Cov hluav taws xob hwj chim nyob rau hauv cov ntaub ntawv no yog ntsuas nyob rau hauv kilomatt / teev (kw / h). Qhov uas nws yog tsim nyog los tswj thiab saib xyuas tau ntawm hluav taws xob hwj chim rau tej yam lub sij hawm ntawm lub sij hawm, thiab koj yuav tsum txuas lub 'meter'.

Hluav taws xob meters yog ib theem thiab peb-theem. Kev twb kev txuas ntawm lub 'meter' ntawm lub xab transformer tam sim no (nyob rau hauv cov ntaub ntawv ntawm indirect kev twb kev txuas), tab sis yuav ua li cas yog tsis muaj lawv (nyob). Installation ntawm lub 'meter' nyob rau hauv lub network nrog ib tug voltage ntawm mus txog 380 volts yuav tsum tau ib tug ntaus ntawv rau ib tug hluav taws xob tam sim no ntawm ntawm 5 mus rau 25 A. Nws yog feem ntau yuav tsum tau. Xaiv yog nqa tawm nyob rau hauv view ntawm lub 'meter' hom. Tam sim no, muaj ob lub ntsiab - yog hluav taws xob thiab induction meters. Yuav kom teb tau cov nqe lus nug raws li uas yog zoo dua - los yog hluav taws xob induction - zoo nkauj yooj yim. Txhua yam nyob rau lub zog uas muab rau lawv.

Induction electrometer raws li nyob rau hauv lub hauv paus ntsiab lus ntawm magnetic rog ntawm lub inductor thiab cov voltage nrog ib tug sib nqus quab yuam txhuas disk. Raws li ib tug tshwm sim ntawm no sis lub xov tooj ntawm revolutions ntawm lub disk yuav muaj kev cuam tshuam thiab lub hwj chim noj. Yuav kom siv cov kev ceev summation counter mechanism. Cov txee yog cov tsis tshua yooj yim, tab sis twb outdated. Lawv yuav tsis pab txhawb multi-rate account thiab tsis muaj lub peev xwm mus rau kis readings remotely. Siv cov 'meter' khiav ntawm lub induction tswvyim - nws yog yooj yim, thiab nyob rau hauv Feem ntau tsis txawm yuav muaj kev tshwj xeeb kev txawj ntse.

Hauv meters yog raws li nyob rau hauv tej daim. Nyob rau hauv xws li tsis muaj feem mus, lawv tsuas hloov Pib ntsais koj teeb ntawm lub tsoov hais nyob rau hauv ib tug ncaj qha proportional npaum li cas. Tej hluav taws xob meters muaj siab ntseeg thiab cov neeg.

Thaum lub sij hawm tus txheej txheem no, raws li txuas lub 'meter', nws yog tsim nyog them sai sai mus ib co ntawm cov tsis muaj kiag li lawm. Nyob rau hauv pem hauv ntej sab yuav tsum tau yuav muab tej xov tooj ntawm disk rotations rau induction 'meter', los yog tus xov tooj ntawm pulses rau lub tshuab hluav taws xob meters, uas sib tau 1 kW / h.

Ib qho tseem ceeb parameter thiab yuav tsum hu mus rau lub chav kawm ntawv ntawm cov neeg ntawm lub fais 'meter'. Qhov no parameter qhia cov neeg kawm ntawv txoj kev ntsuas kev ua yuam kev. Tsis tas li ntawd, tus ntaus ntawv ntawm lub tariff yuav tsum tau hu ua lub tseem ceeb tshaj plaws parameter, thiab xyuam xim rau nws thaum xws li ib tug txheej txheem, cov kev twb kev txuas 'meter'. Kom txog rau thaum nyuam qhuav, yuav luag tag nrho cov txee uas yog siv nyob rau hauv lub neej txhua hnub, yog nruj me ntsis ib-rate. Niaj hnub nimno cov meters yuav kom cov ntaub ntawv thiab lub sij hawm ntawm lub hnub thiab txawm lub sij hawm ntawm lub xyoo.

Multirate xaiv yog pab rau cov neeg siv: ib tug system tsim rau tej hluav taws xob lub zog meters, tso cai rau koj yuav tau hloov tus nqi ntawm hnub los hmo ntuj (hmo ntuj tariff yog ho qis tshaj motivates cov neeg siv kom equalize lub hnub load nkhaus).
