Lub ntsuas hluav taws xob ntsuas hluav taws xob ntsuas hluav taws xob ntau npaum li cas tus neeg siv siv, thiab siv hluav taws xob ntau dua, nws suav ntau dua. Lub 'meter' nws tus kheej puas yuav siv hluav taws xob?
Lub induction meter yog qhov peb feem ntau hu ua turntable meter. Muaj ib qho txhuas turntable hauv lub 'meter'. Thaum muaj hluav taws xob muaj txiaj ntsig, lub turntable yuav tig. Lub txee txuas nrog lub turntable tuaj yeem suav cov kev siv hluav taws xob. Muaj pes tsawg. Nws cov qauv sab nrauv zoo li no:
Sab nraud qauv ntawm induction meter
Tus naj npawb ntawm cov kiv puag ncig qhia tias muaj pes tsawg lub kiv puag ncig ntawm lub tshuab hluav taws xob ua rau ib zaug, thiab qhov ntsuas ntawm lub txee nce los ntawm ib qho sib xws rau ib lub kiv puag ncig.
Nws cov qauv hauv thiab xaim zoo li no:
1 sawv cev rau cov tub ntxhais hlau ntawm lub zog hluav taws xob, 2 lub phaj txhuas ntawm lub ntsuas hluav taws xob, 3 sawv cev rau cov tub ntxhais hlau ntawm lub caij tam sim no, thiab R yog sib npaug rau cov khoom siv hluav taws xob.
Txij li thaum lub zog hluav taws xob hlau thiab cov tub ntxhais hlau tam sim no raug mob nrog cov xov hlau, thiab cov xov hlau muaj kev tiv thaiv, nws tau hais tias thaum twg cov khoom siv hluav taws xob siv hluav taws xob siv hluav taws xob, qee qhov hluav taws xob hluav taws xob tau noj hauv lub ntsuas. Kev noj ntau npaum li cas? Peb tuaj yeem kwv yees:
Raws li cov kev cai hauv lub tebchaws, lub zog poob ntawm qhov hluav taws xob hluav taws xob ntawm lub ntsuas hluav taws xob nrog qib 2 yuav tsum tsis pub tshaj 2 watts ib teev. Lub zog siv hluav taws xob ntawm lub ntsuas hluav taws xob ntawm lub ntsuas hluav taws xob dav dav yog nruab nrab ntawm 0.7 thiab 1.5, thiab cov kauj tam sim no yog kwv yees li 0.5 watts. . Siv tus nqi nruab nrab ntawm qhov voltage coil 1.1 watts los xam:
1.1 (Watts) × 24 (Hours) × 30 (Hnub)=792 (Watt teev). Txij li thaum 1 kilowatt teev hluav taws xob yog 1 kilowatt teev, nws yog 0.792 degrees;
Tam sim no kauj: {{0}}.5 (watts) × 24 (teev) × 30 (hnub)=360 (watt teev), uas yog 0.36 degrees;
Yog li tag nrho cov kev siv nyob rau hauv ib lub hlis yog 1.182 kWh. Yog li, ntxiv 1 kWh rau kev nyeem ntawv ntawm txhua tsev neeg yog tag nrho lub zog siv ntawm tsev neeg no.
