Meter siv los ntsuas hluav taws xob
Lub ntsuas hluav taws xob hluav taws xob yog ib qho cuab yeej siv los ntsuas lub zog hluav taws xob, tseem hu ua watt-teev meter, hluav taws kub ntsuas, thiab kilowatt-teev meter, uas yog hais txog cov cuab yeej ntsuas hluav taws xob ntau ntau.
Thaum siv lub ntsuas hluav taws xob hluav taws xob, xyuam xim rau qhov ntawd, yog tias qhov hluav taws xob tsawg (tsis ntau tshaj 500 volts) thiab tam sim no me me (tsawg amperes), lub ntsuas hluav taws xob hluav taws xob tuaj yeem txuas ncaj qha rau hauv Circuit Court rau kev ntsuas. Nyob rau hauv cov ntaub ntawv ntawm high voltage los yog siab tam sim no, lub zog hluav taws xob ntsuas tsis tuaj yeem txuas ncaj qha rau cov kab, thiab yuav tsum siv lub tshuab hluav taws xob los yog tam sim no transformer.
txhim kho
Nrog rau txoj kev loj hlob sai ntawm kuv lub teb chaws kev lag luam, qhov kev thov rau hluav taws xob los ntawm txhua qhov chaw ntawm lub neej yog nce, thiab kev siv hluav taws xob tsis sib xws ntawm cov sij hawm sib txawv kuj tseem hnyav dua. Txhawm rau txo qhov kev tsis sib haum xeeb ntawm cov khoom siv hluav taws xob thiab kev xav tau hauv kuv lub teb chaws, kho qhov nkhaus load, thiab txhim kho qhov tsis sib xws ntawm kev siv hluav taws xob, ua kom tag nrho lub ncov, tiaj tus, thiab hav lub sijhawm siv hluav taws xob, "txiav ncov thiab sau hav", thiab txhim kho lub teb chaws txoj kev siv hluav taws xob thiab tsim nyog Siv cov khoom siv hluav taws xob, lub zog hluav taws xob hauv qee lub xeev thiab lub nroog hauv Suav teb tau pib maj mam qhia ntau tus nqi hluav taws xob hluav taws xob ntsuas kom them cov neeg siv hluav taws xob siv sijhawm sib koom.
Thaum lub Plaub Hlis 1995, National Planning Commission, Lub Xeev Economic thiab Trade Commission, thiab Ministry of Electric Fais Fab Kev Lag Luam tau sib koom ua kev txiav txim siab ntawm National Electricity Planning Work Conference hauv Shanghai. Nws yuav siv sij hawm 3 mus rau 4 xyoo los npaj thiab ua ib kauj ruam hauv txhua daim phiaj hluav taws xob loj thoob plaws lub tebchaws. Ua tib zoo siv lub peak-valley lub sij hawm-ntawm-siv tus nqi. Lub hom phiaj tag nrho yog hloov pauv 10 feem pua mus rau 15 feem pua ntawm lub zog siab tshaj plaws los ntawm txhua lub network, thiab ua tiav kev hloov pauv ntawm 10-20 lab kilowatts ntawm lub zog siab tshaj plaws thoob plaws lub tebchaws. Lub peev txheej ntawm kev siv tsis yog rau cov neeg siv khoom lag luam thiab kev lag luam nkaus xwb, tab sis kuj yog kev siv hluav taws xob tsis yog kev lag luam thiab kev ua liaj ua teb. Nyob rau hauv cov cheeb tsam uas tej yam kev mob tso cai, uas yog, nyob rau hauv lub cheeb tsam ntawm hluav taws xob hluav taws xob cov cheeb tsam uas tau siv ib tsev neeg, ib 'meter', kuj tseem yuav tau npaj kev txhim kho ntawm cov hluav taws xob siv hluav taws xob tsawg thiab kev siv lub ncov thiab hav hluav taws xob nqi kom nce tus nqi siv hluav taws xob thiab txhim kho kev siv hluav taws xob zoo ntawm cov neeg nyob hauv. Siv lub sijhawm sib txawv thiab cov qauv them nqi sib txawv rau cov neeg siv hluav taws xob. Txhawb kom siv hluav taws xob thaum lub sij hawm qis.
Xyoo 1980, Henan Xeev tau npaj siab los ntsuas lub zog hluav taws xob raws li lub sijhawm ncov thiab hav dej, thiab txhawb nqa kev siv hluav taws xob tsim nyog, sib npaug thiab kev tshawb fawb los ntawm kev lag luam, thiab tom qab ntawd pib ua cov haujlwm sim. Los ntawm kev xyaum, qee qhov kev paub tseem ceeb tau pib tshawb nrhiav. . Tom qab ntawd, Shanxi Xeev tau ua tiav kev sib koom ua haujlwm ua haujlwm hauv qee cov neeg siv hluav taws xob siv cov khoom siv yooj yim.
Los ntawm 1982 txog 1985, ntau lub xeev, nroog thiab cheeb tsam thoob plaws lub tebchaws kuj tau ua tiav kev siv lub sijhawm siv hluav taws xob ntsuas hluav taws xob thiab lub tshuab them nyiaj tshiab hloov kho rau qhov no, thiab ua tiav cov txiaj ntsig zoo. Qee lub tuam txhab hluav taws xob loj loj kuj tseem suav tias yog cov ntsiab lus tseem ceeb ntawm kev txhim kho thev naus laus zis thiab yog ib qho tseem ceeb rau kev tsim hluav taws xob siv hluav taws xob. Txog tam sim no, peb lub teb chaws tau nce mus rau qib ntawm cov teb chaws uas siv ntau yam ntawm cov nqi hluav taws xob raws li kev tswj hwm kev pabcuam thiab tswj cov khoom siv hluav taws xob.
Thawj-tiam quartz moos-tswj lub sij hawm sib koom watt-teev meter yog tsim nyob rau hauv thaum ntxov hnub. Hom hluav taws xob hluav taws xob ntsuas hluav taws xob no tsav lub ncov thiab hav hluav taws xob cov txee los ntawm cov xaim txuas nrog lub moos quartz hauv ntau lub sijhawm sib txawv, thiab feem ntau qhia txog lub ncov thiab hav lub zog thiab tag nrho lub zog. Lub ncov thiab hav lub zog yog rho tawm los ntawm tag nrho lub zog kom tau txais lub zog lub sijhawm ib txwm muaj. Vim qhov kev ntseeg tsis zoo ntawm lub sijhawm sib koom meter. Lub sij hawm segmentation raug yog tsawg dhau (qhov tsawg kawg nkaus segmentation yog 5min), nws raug cuam tshuam los cuam tshuam, lub sijhawm hloov kho kuj muaj teeb meem ntau dua, kev siv ua haujlwm yog ib leeg, thiab nws tsis tuaj yeem ua tau raws li qee qhov tshwj xeeb hauv kev sib koom them nqi. Nws tau raug tshem tawm thiab ua tsis taus.
Qhov thib ob tiam ntawm lub sij hawm sib koom watt-teev meter nrog mechatronics qauv. Hom hluav taws xob ntsuas hluav taws xob no txais yuav 1.0-theem induction system hluav taws xob ntsuas hluav taws xob txav raws li lub hauv paus, txais yuav infrared photoelectric converter, pulse output thiab central processing unit (CPU), single-chip circuit, thiab siv cov keyboard txuas programming lossis infrared wireless keyboard kom ua tiav ntau yam kev xav tau. Cov kev teeb tsa ntawm, moos, lub sijhawm, thiab hnub so tuaj yeem tiv thaiv cov zaub thiab khaws cia ntawm qhov xav tau siab tshaj plaws ntawm lub hlis no, qhov kev thov siab tshaj plaws ntawm lub hli dhau los, thiab lub ncov, tiaj tus, thiab hav qhov xav tau siab tshaj plaws ntawm lub hlis no. Nrog rau cov zis mem tes thiab RS-232 serial kev sib txuas lus chaw nres nkoj, nws yooj yim rau cov ntaub ntawv xa mus thiab saib xyuas cov chaw taws teeb. Qhov kev ua tau zoo ntawm cov cuab yeej yog qhov tseeb dua thiab txhim khu kev qha, thiab cov haujlwm tuaj yeem ua tau raws li cov kev xav tau ntawm lub sijhawm tam sim no ntawm peb lub teb chaws. Cov txheej txheem ntau lawm yog tus paub tab thiab tus nqi sib tw. Nws yog cov khoom siv ntau tshaj plaws nyob rau hauv Suav teb. Tab sis yoov nyob rau hauv cov tshuaj pleev yog tias txhua lub chaw tsim khoom tsim nws tus kheej siab microcontroller, uas muaj qhov tsis zoo ntawm cov khoom tsis zoo sib xws thiab kev saib xyuas nyuaj. Feem ntau siv hauv cov khoom lag luam no yog DF68, DF93, DTF33, DF86, DSF20, DIF2, DF32, DTF864, MRZ, DSD66, thiab lwm yam.
