Yog tias koj tawm tsam kom txuag hluav taws xob, tab sis cov ntawv txais nyiaj tseem ceeb, nws yuav tsis yog koj qhov teeb meem. Koj lub txee tuaj yeem ua lub neej zais cia ntawm nws tus kheej.

Lub ntsuas hluav taws xob yog ib yam uas txhua tus yuav tsum tau ua. Thiab nws tsis muaj teeb meem yog tias koj yog techie lossis humanist, koj yuav tsum nkag siab txog lub cuab yeej. Nws nyob ntawm seb koj yuav tsum them nyiaj npaum li cas rau lub teeb thaum kawg ntawm lub hli. Yog tias koj tsuas paub txog lub ntsuas hluav taws xob uas nws dai qhov chaw ntawm txoj kev hauv tsev, thiab qee zaum cov neeg hauv txhua qhov tuaj yeem "sib nyeem", xav txog nws. Tej zaum nws tau ua haujlwm tsis raug rau lub sijhawm ntev thiab nws yog lub sijhawm los hloov nws?

Thaum twg yog lub sijhawm hloov lub ntsuas hluav taws xob

Raws li txoj cai tam sim no, lub ntsuas hluav taws xob raug txiav txim siab yog tias:

1. Kev ntsuas ntsuas tsis tshwm sim.
2. Muaj kev ua txhaum cai ntawm kev tswj cov ntsaws ruaj ruaj thiab (lossis) cov cim pov thawj.
3. Muaj kev puas tsuaj rau lub cuab yeej.
4. Qhov kev tso cai yuam kev ntawm cov lus qhia tau dhau lawm.
5. Lub sijhawm calibration ntawm lub cuab yeej tau tas sijhawm.

Cov txiaj ntsig ntsuas tsis tshwm sim / tsis muaj kev foob / muaj kev puas tsuaj rau cov tshuab

Ntsuas qhov pom ntawm koj lub 'meter'. Nws yog lub sijhawm los hloov nws yog tias:

1. Lub disc ntawm induction meter tsis tig los yog rotates jerkily.
2. Cov zaub lossis qhov taw qhia tsis ua haujlwm rau lub ntsuas hluav taws xob hluav taws xob.
3. Lub foob kev ruaj ntseg raug torn los yog cov ntawv nplaum tshwj xeeb puas lawm.
4. Qhov nruj ntawm lub meter lub cev yog tawg, muaj los ntawm qhov los yog tawg.
5. Pom iav puas los yog tawg.

Lub 'meter' tsis raug qhia txog cov hluav taws xob siv

Lub txee ua haujlwm thaum cov khoom siv hluav taws xob tua

Qhov tshwm sim no hu ua self-propelled. Txhawm rau tshem tawm nws, nws yog qhov txaus los ua qhov kev sim yooj yim: tua tag nrho cov keyboards ntawm lub vaj huam sib luag, tshwj tsis yog rau qhov hloov pauv (tsim rau lub ntsuas). Yog li, koj yuav de-energize lub tsev, tab sis tawm ntawm lub ntsuas hluav taws xob ua haujlwm. Thiab tam sim no koj yuav tsum ua tib zoo saib xyuas lub disk lossis qhov taw qhia lub teeb ntawm lub txee.

Tsis txhob mus rau hauv lub flap yam tsis muaj kev paub txog yam tsawg kawg nkaus ntawm txoj cai kev nyab xeeb: hluav taws xob tsis yog khoom ua si! Thiab tsis txhob hnov qab, ua ntej tua lub hwj chim rau lub tsev, txuag tag nrho cov ntaub ntawv ntawm lub computer thiab tua cov khoom siv complex.

Yog hais tias tsis muaj tus kheej-propelled ntaus ntawv nyob rau hauv lub ntaus ntawv, ces nyob rau hauv 15 feeb lub disk yuav ua tsis tau ntau tshaj ib tug ua tiav kiv puag ncig, thiab qhov taw qhia yuav ntsais tsis ntau tshaj ib zaug. Nws puas tshwm sim ntau zaus? Qhov no txhais tau hais tias lub ntsuas hluav taws xob ua rau cov ntawv nyeem nws tus kheej, thiab koj them nyiaj ntau dhau.

Cov chav kawm raug ntawm cov cuab yeej tsis ua raws li kev cai tswj hwm

Txhua lub ntsuas hluav taws xob muaj nws cov chav kawm raug. Nws qhia txog qhov tso cai ntsuas qhov yuam kev. Cov chav kawm raug ntawm lub txee yog qhia ntawm lub dial hauv ib lub voj voog:

Raws li txoj cai tam sim no, tsuas yog ntsuas cov khoom siv nrog cov chav kawm raug ntawm 2, 0 thiab siab dua (uas yog, 1, 5 lossis 1) tuaj yeem siv. Qhov no txhais tau hais tias xws li ib tug ntaus ntawv yuav tso saib lub expended 100 watts nrog ib tug yuam kev ntawm ib tug ntau ntawm 2%: los ntawm 98 mus rau 102 watts.

Yog tias koj lub ntsuas ntsuas muaj qhov tseeb ntawm 2, 5, lub cuab yeej yuav tsum tau hloov. Txij li thaum nyob rau hauv rooj plaub no, lub tuam txhab muab hluav taws xob tuaj yeem raug cai tsis lees txais nws cov ntawv nyeem rau kev suav thiab thov kom them nyiaj rau lub teeb raws li cov qauv tsim nyog. Thiab lawv tej zaum yuav siab dua koj qib noj.

Qhov kev ntsuas yuam kev yog ntau dua li qhov tau hais tseg

Txawm hais tias chav kawm raug raug raug, lub cuab yeej yuav tsis raug suav nrog kev siv hluav taws xob. Txawm hais tias overestimate (uas ua rau peb them nyiaj ntau dhau), lossis qis dua qhov kev nyeem ntawv (thiab rau qhov no, lub koom haum muab hluav taws xob tuaj yeem nqa cov lus foob tawm tsam koj). Nws yog ib qho yooj yim mus kuaj xyuas kev noj qab haus huv ntawm lub 'meter'.

1. Tua txhua yam khoom siv hluav taws xob hauv tsev.
2. Cov ntsuas ntsuas yuav tsum tsis txhob hloov tom qab ntawd: sau los yog nco ntsoov lawv.
3. Hloov ntawm ib qho khoom siv nrog kev paub siv hluav taws xob. Piv txwv li, ib lub teeb 100 watt.
4. Txheeb xyuas qhov ntsuas ntsuas tom qab ib teev. Lawv yuav tsum tau nce raws nraim los ntawm theem ntawm kev siv hluav taws xob ntawm cov khoom siv hloov pauv. Nyob rau hauv cov ntaub ntawv ntawm lub teeb, nyeem ntawv yuav tsum hloov los ntawm 0.1 kW.
5. Yog tias qhov ntsuas ntsuas qhov sib txawv, lawv yuav tsum sib txawv ntawm qhov xav tau los ntawm qhov yuam kev muab los ntawm nws cov chav kawm raug, uas yog, los ntawm qhov siab tshaj ntawm 2%.
6. Yog tias qhov kev tso cai yuam kev dhau lawm, nws yog lub sijhawm los hloov lub ntsuas.

Lub sijhawm calibration ntawm lub cuab yeej tau tas sij hawm

Lub sijhawm calibration yog lub sij hawm thaum lub sijhawm ua haujlwm ntawm ib lub cuab yeej tshwj xeeb yog lav. Nws yog ntsia los ntawm cov chaw tsim khoom, qhia nyob rau hauv cov ntaub ntawv nrog rau lub 'meter' thiab feem ntau yog 6-16 xyoo. Thaum lub sijhawm no xaus, lub ntsuas hluav taws xob yuav tsum tau kuaj xyuas. Qhov no tuaj yeem ua tiav los ntawm kev xa daim ntawv thov mus rau lub chaw pabcuam ntawm lub koom haum muab hluav taws xob.

Saib hauv daim ntawv qhia cov ntaub ntawv ntawm koj lub ntsuas ntsuas. Yog hais tias lub sij hawm calibration tau tas sij hawm ntev dhau los, lub meter yuav tsum tau hloov.

Los ntawm txoj kev, yog tias koj tseem siv lub ntsuas hluav taws xob los ntawm xyoo 1950-1980s, thiab koj lub tsev muaj cov khoom siv niaj hnub no, nws yog lub sijhawm los suab lub tswb. Cov meters ntawm lub xyoo pua xeem tsis yog tsim los ua haujlwm nrog cov khoom siv hluav taws xob hauv tsev. Kev phom sij hluav taws tuaj yeem tshwm sim vim yog overcurrent loading.

Yuav ua li cas xaiv lub ntsuas hluav taws xob tshiab

Cov cuab yeej hluav taws xob ntsuas hluav taws xob yuav tsum tau xaiv tsis yog hauv cov tsos thiab tus nqi, tab sis kuj raws li kev xav tau.

Cov txee yog ib qho thiab peb theem. Txhawm rau xaiv qhov raug, txiav txim siab pes tsawg theem koj lub network muaj. Qhov no tuaj yeem ua tau ntau txoj hauv kev:

1. Saib cov kab twg yog qhov tsim nyog rau lub tshuab nkag thiab ntsuas. Yog hais tias nws muaj ob lub conductors (theem thiab xoom), koj yuav tsum tau ib lub meter ib-theem. Yog hais tias muaj plaub cores (peb theem thiab xoom), yuav tsum muaj ib qho multiphase.
2. Saib cov qhab nia ntawm lub txee qub. Yog tias tsuas yog ib tus lej qhia rau nws (220 lossis 230 V), muaj ib theem hauv lub network. Yog tias muaj ob peb (220/380 lossis 230/400 V) - peb.

Tus naj npawb ntawm cov khoom siv hluav taws xob

Ib qho tseem ceeb rau kev xaiv ib lub 'meter' yog qhov siab tshaj plaws tam sim no uas tuaj yeem dhau los ntawm nws. Rau cov neeg siv hluav taws xob zoo tib yam, tus nqi ntawm 40-60 A yuav txaus, txawm li cas los xij, yog tias koj chav tsev tau ntim nrog cov khoom siv niaj hnub, nws yog qhov zoo dua los xaiv ib lub 'meter' nrog cov npoo. Yog tias qhov kev khiav hauj lwm tam sim no ntau dua qhov siab tshaj plaws, lub 'meter' yuav hlawv tawm.

tariff txoj kev npaj

Xyuas seb koj them tus nqi li cas rau lub teeb: dav dav (ib nqi ib kW) lossis "hnub-hmo" (thaum tsaus ntuj, tus nqi ntawm kW qis dua). Xaiv lub txee nyob ntawm qhov no. Nyob rau hauv ntau qhov system, nws yuav muaj peev xwm saib tus neeg nyeem ntawv raws sijhawm ntawm hnub.

Mounting txoj kev

Cov 'meter' sib txawv yog ntsia nrog bolts lossis ntawm ib qho kev tsheb ciav hlau tshwj xeeb. Saib ntawm lub mount ntawm cov cuab yeej qub thiab xaiv cov qauv tsim nyog. Txhawm rau kom tsis txhob muaj teeb meem nrog lub mount, nqa ib daim duab ntawm lub vaj huam sib luag hluav taws xob thiab qhia rau tus kws pab tswv yim hauv khw.

Ntaus ntawv tso tawm hnub

Them mloog mus rau lub hnub nyoog ntawm lub 'meter'. Ib theem yuav tsum tau tso tawm tsis pub ntau tshaj ob xyoos dhau los, thiab peb theem - tsis pub ntau tshaj ib xyoos. Txwv tsis pub, ua ntej kev teeb tsa, koj yuav tsum tau ua cov txheej txheem pov thawj ntawm lub 'meter'. Hnub tim ntawm qhov teeb meem yog qhia rau ntawm lub vaj huam sib luag ntawm lub ntsuas hluav taws xob lossis hauv phau ntawv hla tebchaws ntawm lub cuab yeej.

Muaj nuj nqi ntxiv

Ntawm no koj tuaj yeem taug kev. Tam sim no lawv tsim cov txee nrog lub teeb pom kev zoo, lub sijhawm thiab hnub tim zaub, lub cim xeeb sab hauv thiab ua-hauv GSM modems. Tag nrho cov no tsis yog qhov tsim nyog los ntsuas qhov tseeb ntawm cov khoom siv hluav taws xob, tab sis nws tuaj yeem pab tau rau koj.

Yuav hloov lub ntsuas hluav taws xob li cas

Yuav ib lub 'meter' tshiab thiab thov kev hloov pauv rau lub tuam txhab hluav taws xob lub tuam txhab cov neeg siv khoom. Tus kws tshaj lij uas tau tso cai los ua cov haujlwm no thiab muaj txoj cai tsim nyog yuav tshem tawm cov qub thiab nruab ib lub cuab yeej tshiab, kaw lub ntsuas thiab sau tag nrho cov ntawv nyeem uas tsim nyog.

Tsis txhob sim hloov lub ntsuas hluav taws xob ntawm koj tus kheej. Nws yog kev hem thawj rau lub neej thiab tsis raug cai.
