Daim duab kab hluav taws xob ib leeg yog tsim los ua kom nws nkag siab tias cov khoom tseem ceeb ntawm Circuit Court nyob li cas thiab qhov sib lawv liag ntawm lawv qhov kev sib txuas yog dab tsi. Nyob rau tib lub sijhawm, cov cim tseem ceeb thiab cov khoom siv hluav taws xob, lawv cov chaw tsim khoom thiab qee qhov kev ntsuas feem ntau tau cuam tshuam los ntawm cov kab kos ib kab.
Ib-kab hluav taws xob hluav taws xob muab hluav taws xob ua haujlwm rau kev pom meej thiab tso cai rau koj nkag siab txog cov ntsiab lus dav dav ntawm Circuit Court. Raws li txoj cai, cov txheej txheem zoo li no yog qhov tsim nyog ntawm thawj theem ntawm kev ua haujlwm nrog cov khoom siv.
Raws li GOST rau kev npaj cov ntaub ntawv tsim qauv rau kev teeb tsa thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob, txhua daim duab yuav tsum muaj lub thwj cim, thaum txhua lub switchgear muaj nws tus kheej tsis, uas yuav tsum tau qhia ntawm daim duab. Cov kev txwv no suav nrog: COS φ, hom cable siv, lub zog thiab tam sim no. Yog tias lub tswv yim tau ua nrog cov khoom siv hluav taws xob, tom qab ntawd lawv qhov chaw yuav tsum tau qhia rau ntawm ib kab kab kos, ntxiv rau, txhawm rau tswj cov khoom siv hluav taws xob niaj hnub hauv switchgear, niaj hnub no.tswj chaw taws teeb. Nws tuaj yeem tso tawm kom pom hauv cov tswj vaj huam sib luag lossis nyob ze rau ntawm tus tsav, thaum lub pob yog tso tawm cais tawm ntawm lub disconnector. Daim duab hluav taws xob ib leeg yuav tsum muaj kev cuam tshuam lawv qhov chaw.
Qhov ntev ntawm cov cables thiab cov txheej txheem ntawm lawv qhov kev teeb tsa tau cuam tshuam nrog qhov tseeb ntawm ib 'meter'. Yog li, tus neeg cog lus nkag siab txog daim duab loj thiab ntsuas cov haujlwm ua ntej.
Daim duab hluav taws xob yuav tsum muaj hom thiab qhov chaw ntawm cov cuab yeej ntsuas ntsuas, nrog rau qhov poob ntawm hluav taws xob thaum sib kis los ntawm cov kab hluav taws xob. Cov tswv yim thiab cov ntaub ntawv tau ruaj ntseg los ntawm kos npe ntawm tus engineer rau kev txhim kho cov ntaub ntawv no.
Ua ntej ib txoj kab hluav taws xob rau ib lub tsev nyob rau hauv kev tsim khoom, nws mus dhau ntawm kev pom zoo. Nyob rau tib lub sijhawm, tsuas yog tus kws tshaj lij uas muaj daim ntawv tso cai los ntawm SRO tuaj yeem sau nws. Lub tuam txhab rau kev tsim cov txheej txheem no yuav tsum yog tus tswv cuab ntawm SRO. Yog tias tus qauv ntsuas hluav taws xob raug tsim yam tsis muaj kev pom zoo tsim nyog, ces nws tsis tuaj yeem txiav txim siab los ntawm cov neeg muaj peev xwm.
Kev ua raws li daim duab kab ib kab yog ib kauj ruam tseem ceeb; nws yuav ua li cas nyob ntawm seb lub zog yuav siv nyiaj txiag li cas. Piv txwv li, nws paub tias tag nrho cov load yog inductive nyob rau hauv cov xwm, txij li thaum motors, fais fab mov thiab transformers feem ntau ua raws li cov neeg siv khoom. Yog li, COS φ txo qis, ua rau muaj kev siv hluav taws xob loj. Txhawm rau zam qhov no, ib txoj kab hluav taws xob ib leeg yog nqa tawm nrog lub txhab nyiaj capacitor. Yog liTxij li thaum lub reactance vectors ntawm lub kauj thiab capacitor yog oppositely qhia, lawv them ib leeg, yog li tsis suav nrog lawv lub hwj chim, COS φ nce, thiab ntau lawm txuag nyiaj.
Txawm li cas los xij, ib lub zog hluav taws xob ib leeg tuaj yeem suav nrog cov tsev txhab nyiaj capacitor thaum nws pom zoo. Piv txwv li, txhawm rau muab hluav taws xob rau cov cheeb tsam me me, txoj hauv kev no tsis yog qhov tsim nyog, txij li kev tiv thaiv kev ua haujlwm feem ntau yeej, tab sis yog tias muaj cov nroj tsuag loj, cov chaw tsim khoom lossis lwm yam hauv cheeb tsam, ces lub tsev txhab nyiaj capacitor tsuas yog tsim nyog.
Cov neeg tsim hluav taws xob yuav tsum ua tib zoo kawm qhov chaw uas hloov pauv ntawm lub zog hluav taws xob tau npaj tseg, thiab kos cov lus xaus.
