Lub ntsuas hluav taws xob hluav taws xob yog lub ntsuas hluav taws xob siv los suav cov hluav taws xob siv hluav taws xob. Nws chav tsev yog "KW·h" (kilowatt teev), uas yog "degree" ntawm qhov hluav taws xob peb feem ntau hais. Lub zog ib txwm ntawm 1kW cov khoom siv hluav taws xob ua haujlwm Cov hluav taws xob siv rau 1h yog 1KW·h (kilowatt·hour), uas txhais tau tias 1 kilowatt-teev hluav taws xob siv.
Cov hluav taws xob hluav taws xob hluav taws xob feem ntau tau muab faib ua ib theem hluav taws xob ntsuas, peb-theem plaub-xaim lub zog hluav taws xob, peb-theem peb-xaim hluav taws xob hluav taws xob thiab cov ntsuas hluav taws xob reactive. Tam sim no muaj ob hom hluav taws xob ntsuas hluav taws xob siv nyob rau hauv kev ua lag luam: txhua yam thiab hluav taws xob.
Cov tshuab hluav taws xob hluav taws xob ntsuas hluav taws xob muaj qhov zoo ntawm qhov siab tshaj thiab tus nqi qis, tab sis tau yooj yim cuam tshuam los ntawm qhov kub, qhov hluav taws xob, zaus thiab lwm yam; hluav taws xob hluav taws xob hluav taws xob ntsuas hluav taws xob siv hluav taws xob sib xyaw ua ke los ua cov khoom siv hluav taws xob hluav taws xob sib txuas, uas muaj qhov tseeb siab, zoo linearity, thiab ua haujlwm. Qhov zoo xws li dav voltage.
Yog li ntawd, hluav taws xob watt-teev meters tau maj mam hloov txhua yam watt-teev meters. Nyob rau hauv lub neej yav tom ntej, hluav taws xob watt-teev meters yuav tsum nyiam thaum xaiv watt-teev meters.
Ib-theem 'meter' tsos thiab technical parameters
Cov tsos ntawm lub zog hluav taws xob ntsuas muaj qhov tsis zoo xws li ntsuas qhov ntsuas hluav taws xob, ntsuas tam sim no, ntsuas qhov ntsuas tam sim no ( ntsuas qhov siab tshaj plaws tam sim no), lub zog zaus, qhov tseeb, thiab lub zog ntsuas qhov tsis tu ncua.
Hluav taws xob ntsuas hluav taws xob zoo li thiab cov kev ntsuas tsis zoo
Piv txwv li, daim ntawv teev npe ntawm ib-theem hluav taws xob hluav taws xob ntsuas hluav taws xob tau cim nrog cov cim hauv qab no: 220V, 5 (20) A, 50Hz, 3200imp / KW·h, uas txhais tau hais tias lub zog ua haujlwm ntawm qhov ntsuas no yog 220V thiab Qhov ntsuas tam sim no yog 5A ( ntsuas qhov siab tshaj plaws tam sim no 20A), Lub zog zaus yog 50Hz, thiab qhov taw qhia hluav taws xob pulse flashes 3200 zaug rau txhua qib ntawm qhov ntsuas hluav taws xob.
5 (20) A tam sim no Tus nqi tam sim no "5" ua ntej cov hlua khi hu ua calibration tam sim no, uas yog siv los xam cov nqi tam sim no ntawm lub load. Qhov me me ntawm qhov ntsuas tam sim no, qhov me me ntawm qhov pib tam sim no ntawm lub 'meter', thiab qhov rhiab ntau lub 'meter'. Qhov pib tam sim no ntawm lub 'meter' yog 0.5 feem pua ntawm qhov ntsuas tam sim no. Yog tias qhov ntsuas tam sim no yog 5A 'meter', qhov tam sim no hauv Circuit Court yuav pib suav yog tias nws siab tshaj 0.025A, thiab lub ntsuas hluav taws xob yuav tsis suav hauv qab tus nqi no. Tam sim no "20" nyob rau hauv brackets yog hu ua qhov ntsuas siab tshaj plaws tam sim no, uas yog hais txog qhov siab tshaj plaws tam sim no tso cai los ntawm lub zog hluav taws xob ntsuas hluav taws xob ua haujlwm nyob rau hauv qhov kev ua yuam kev ntev. Lub ntsuas hluav taws xob hluav taws xob tuaj yeem ua haujlwm nyob rau hauv qhov ntsuas siab tshaj plaws tam sim no, tab sis nws yuav tsum tsis txhob tshaj qhov tam sim no rau kev siv mus ntev.
Cov mem tes tas li ntawm lub ntsuas hluav taws xob yog 3200imp / KW·h. Lub ntsuas pulse ntawm lub ntsuas hluav taws xob yuav flash thaum siv hluav taws xob. Thaum lub ntsuas pulse flashes 3200 zaug, tus lej ntawm tus lej ntawm lub txee yuav nce los ntawm ib qho, qhia tias 1KW·h (degree) tau siv. Hluav taws xob.
Qee lub sij hawm yog tias koj pom lub ntsuas hluav taws xob hauv tsev sai sai, nws txhais tau tias qhov kev siv tam sim no kuj loj heev. Thaum lub ntsuas pulse tseem ceeb thaum tsis muaj cov khoom siv hauv tsev, koj yuav tsum xyuas seb puas muaj hluav taws xob raug nyiag lawm.
Ib-theem meter txuas txoj kev
Ib-theem hluav taws xob ntsuas hluav taws xob kuj tau muab faib ua ncaj nraim-los ntawm kev sib txuas-inductance hom. Feem ntau, ib-theem hluav taws xob meters los yog ncaj-los ntawm meters yog ntau heev. Piv txwv li, peb cov ntsuas hluav taws xob hauv tsev niaj hnub yog txhua qhov ncaj-los ntawm ib-theem meters, thiab muaj cov xwm txheej tshwj xeeb uas tam sim no tshaj qhov ntsuas hluav taws xob. Kev ntsuas ntau yuav tsum tau yuav lub tshuab hluav taws xob hluav taws xob hluav taws xob ntsuas hluav taws xob.
Yog li yuav ua li cas xaim lub ntsuas ib-theem? Qhov tseeb, muaj cov kab kos duab ntawm lub npog ntawm txhua lub ntsuas hluav taws xob (tshwj xeeb tshaj yog daim duab kab hluav taws xob ntawm lub transformer hom hluav taws xob ntsuas hluav taws xob).
Kev sib txuas ib qho: kev sib txuas ncaj qha
(1) Kab 1 mus rau hauv, thiab kab 2 tawm mus.
(2) Kab 3 tawm mus, thiab kab 4 tawm mus.
Txoj kev sib txuas 2: Transformer hom thaiv
(1) No. 1 thiab No. 2 ports txuas nrog K1 thiab K2 ntawm lub transformer.
(2) Kab 3 txuas nrog rau kab, thiab kab 4 txuas nrog cov kab nruab nrab.
Qhov kev xaiv ntawm lub zog hluav taws xob ntsuas qhov muaj peev xwm tsis yog qhov loj dua qhov zoo dua, lossis qhov me dua qhov zoo dua, nws yuav tsum phim lub zog siv. Xaiv lub peev xwm loj dhau los yog tsawg dhau yuav ua rau qhov ntsuas tsis raug, tshwj xeeb tshaj yog thaum lub peev xwm ntawm lub ntsuas hluav taws xob hluav taws xob me me, lub ntsuas hluav taws xob hluav taws xob yog qhov yooj yim rau hlawv. Yog li ntawd, lub peev xwm tam sim no yuav tsum raug xam rau qhov siab tshaj plaws tam sim no ntawm tag nrho cov khoom siv hluav taws xob ua ke, thiab nws raug nquahu kom siv lub watt-teev meter nrog lub peev xwm loj dua.
