Nyob rau hnub no thiab hnub nyoog, tej zaum koj yuav tsis muaj lub moos, tab sis koj yuav tsum muaj lub ntsuas hluav taws xob hauv koj lub tsev. Raws li kev ntsuas ntsuas cuam tshuam nrog tib neeg txoj kev ua neej, lub ntsuas hluav taws xob yog ib qho tseem ceeb rau kev ntsuas hluav taws xob thiab kev them nqi hluav taws xob.
1. Los ntawm qhov pom ntawm lub ntsuas hluav taws xob, lub ntsuas hluav taws xob zoo li cas yog lub ntsuas hluav taws xob hluav taws xob uas ua tau raws li kev cai lij choj?
Lub npe ntawm lub ntsuas hluav taws xob yuav tsum muaj tsawg kawg yog cov ntaub ntawv hauv qab no: lub npe, qauv, tus lej lej, qib raug, qhov tsis tu ncua ntawm lub zog hluav taws xob ntsuas, siv zaus, siv hluav taws xob, siv tam sim no thiab siab tshaj tam sim no, cov khoom lag luam tus qauv raws li kev tsim khoom. Lub tuam txhab lub npe lossis cov cim lag luam, hnub tsim khoom, chav ntsuas, tus lej ntawm tus lej lej lossis ntau tus nqi qhia. Tsis tas li ntawd, lub ntsuas hluav taws xob tsim nyog yuav tsum muaj cov cim hauv qab no:
(1) Daim ntawv teev npe ntawm lub ntsuas hluav taws xob yuav tsum muaj lub teb chaws ntsuas thiab tsim daim ntawv tso cai (CMC) lub logo thiab daim ntawv tso cai naj npawb;
(2) Lub plhaub ntawm lub ntsuas hluav taws xob hluav taws xob yuav tsum tau txuas nrog daim ntawv pov thawj ntawm lub koom haum pov thawj thiab cim nrog lub sijhawm siv tau;
2. Lub ntsiab lus ntawm lub npe ntawm lub ntsuas hluav taws xob hluav taws xob yog dab tsi?
Ntawm daim ntawv teev npe ntawm lub ntsuas hluav taws xob hluav taws xob, peb tuaj yeem pom cov ntsiab lus hauv qab no: ib-theem, peb-theem, active, reactive, thiab lwm yam. Lub nameplate kuj tau cim nrog cov qauv sau npe: xws li DDS × × ×, thawj D stands rau "electric zog meter", qhov thib ob D stands rau "ib-theem", thiab S yog lub prefix ntawm "static type (feem ntau hu ua electronic type)" hauv lus Askiv. . "×××" sawv cev rau cov meters sib txawv uas tsim los ntawm cov tuam txhab sib txawv. Hauv kuv lub tebchaws, qhov hluav taws xob ntawm 220V tau txais yuav, thiab qhov zaus ntawm kev hloov tam sim no yog 50Hz. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov cim tam sim no: piv txwv li, 5 (20) A txhais tau tias qhov tam sim no yooj yim yog 5A thiab qhov siab tshaj plaws tam sim no yog 20A.
3. Vim li cas lub teeb liab ua kom ci thaum lub ntsuas hluav taws xob siv?
Yuav muaj lub teeb liab liab ntawm txhua lub 'meter' - lub teeb mem tes, lub ntsuas pulse ntawm lub ntsuas yuav flash thaum siv hluav taws xob. "1600imp / kWh" cim nyob rau hauv lub meter nameplate yog mem tes tas li, mem tes tas li yog tus naj npawb ntawm pulses ib kWh, uas txhais tau hais tias cov neeg siv khoom siv 1 kWh ntawm hluav taws xob, thiab lub teeb mem tes flashes 1600 zaug. Lub flashing zaus ntawm lub teeb mem tes sib txawv nrog lub zog load. Lub zog loj dua, qhov kev siv hluav taws xob sai dua yuav raug, thiab lub teeb mem tes nrawm dua yuav flash.
4. Yuav ua li cas kom nkag siab txog cov lus qhia tam sim no ntawm lub ntsuas hluav taws xob hluav taws xob?
Lub peev xwm ntawm lub ntsuas hluav taws xob hluav taws xob yog sawv cev los ntawm qhov siab tshaj plaws tam sim no. Piv txwv li, qhov parameter ntawm qee yam hluav taws xob ntsuas hluav taws xob yog 220V, 5 (20) A, uas txhais tau hais tias qhov ntsuas hluav taws xob ntsuas hluav taws xob yog 220V, qhov tam sim no yooj yim yog 5A, thiab qhov ntsuas siab tshaj plaws tam sim no yog 20A. Yog tias qhov load tshaj qhov siab tshaj plaws tam sim no ntawm lub ntsuas hluav taws xob, lub ntsuas hluav taws xob hluav taws xob tuaj yeem kub hnyiab lossis ua rau hluav taws kub.
5. Vim li cas lub ntsuas hluav taws xob yuav tsum tau tig ib ntus?
Nrog rau lub sijhawm ntev ntawm kev siv lub zog hluav taws xob ntsuas hluav taws xob, cov khoom siv hluav taws xob los yog kev laus ntawm cov khoom siv hluav taws xob yuav tshwm sim, uas feem ntau ua rau kev ntsuas qhov yuam kev dhau qhov kev txwv thoob ntiaj teb tso cai yuam kev. Txhawm rau txhawm rau txhawm rau ntsuas qhov tseeb ntawm lub ntsuas hluav taws xob hluav taws xob, nws yog ib qho tsim nyog yuav tsum tshem tawm lub ntsuas hluav taws xob hluav taws xob rau kev txheeb xyuas raws sij hawm raws li cov kev cai ntawm lub xeev.
6. Puas yog cov ntsuas ntsuas ntse mus nrawm dua li cov ntsuas ntsuas?
Cov ntsuas ntse yog qhov rhiab tshaj li cov ntsuas ntsuas. Siv cov khoom siv hluav taws xob ntawm ob peb watts lossis txawm tias ob peb feem kaum ntawm watts, cov khoom siv hluav taws xob ib txwm tig qeeb qeeb lossis tsis tig txhua, tab sis ntse ntsuas ntsuas tau raug, thiab txhua qhov me me tam sim no yuav ua rau lub ntsuas ntsuas tig.
Tsis tas li ntawd, cov ntsuas hluav taws xob ib txwm siv feem ntau yog "inductive hluav taws xob ntsuas" uas lub disc tig nrog hluav taws xob noj. Lub disc yog txhawb los ntawm ib tug bearing. Sij hawm dhau mus, cov kabmob maj mam muaj hnub nyoog, kev sib txhuam nce, thiab kev sib hloov ceev yuav qeeb qeeb, them nyiaj ntau dua qhov kev siv tiag tiag. Nrog tsawg zog, ntse meters yuav tsis muaj qhov ntawd.
Kev txuag hluav taws xob txhawb nqa los ntawm cov ntsuas ntse ntse yog qhov tseem ceeb tshaj plaws los txhawb cov neeg siv kom hloov lawv txoj kev ua neej nyob ntawm kev siv hluav taws xob thiab txhim kho txoj kev siv hluav taws xob. Ua tib zoo saib xyuas cov ntsiab lus ntawm kev siv hluav taws xob.
